What is an LED video processor?

An LED video processor, often referred to as the “brain” of an LED display system, is a specialized hardware device designed to take video input signals, process them, and deliver them in a way that the LED display can properly interpret and display.

While LED screens can display a variety of resolutions, they often rely on video processors to ensure that the input video is compatible with the screen’s resolution, aspect ratio, and color settings.

What are the components of an LED video processor?

An LED video processor is composed of several key components, including an input interface module (for receiving various video signals), a signal processing chip (responsible for image processing and signal conversion), an output interface module (for transmitting the processed signal to the LED display), a control system (for managing display settings), and memory and power modules (to ensure stable system operation). These components work together to ensure that video signals are displayed on the LED screen with optimal quality.

How does an LED video processor work?

An LED video processor acts as an intermediary between the video source (e.g., a computer, camera, or media player) and the LED display. Here’s a step-by-step look at how the processor controls the LED screen:

Signal conversion

The LED video processor can receive input signals from different sources such as HDMI, DVI or VGA. The processor converts these signals into a format that the LED display can understand. Different displays may have different requirements, so this conversion process ensures that the screen works regardless of the signal source.

Scaling and resolution matching

One of the main functions of an video processor is to adjust the resolution of the input video to match the original resolution of the LED screen. For example, if the LED screen resolution is 1920×1080 and the input video is 1280×720, the processor will enlarge the video to fit the screen without losing quality. Correct scaling ensures that content is not distorted or pixelated.

Color correction and calibration

LED displays require precise color control to ensure that content is vibrant and accurate. LED video processors adjust parameters such as color range, brightness, and contrast to optimize image quality. This is especially important for large displays, where consistent color and brightness are essential.

Image processing

To further enhance video quality, video processors use a variety of image processing techniques. These techniques include deinterlacing, noise reduction, and motion compensation, which help eliminate visual imperfections and improve image clarity.

Multi-window and picture-in-picture (PIP) capabilities

Advanced LED video processors allow users to display multiple video sources simultaneously. This feature is useful for large events or digital signage, where multiple content can be displayed simultaneously. For example, you can display live videos, slideshows, and logos in different areas of the same screen.

Synchronization and latency reduction

LED video wall processors ensure that all parts of a large display remain in sync. Without synchronization, different screen areas may display different video frames, resulting in inconsistent images. Modern video processor also minimize latency, ensuring that the content displayed on the screen is as close to real-time as possible.

Edge blending and image stitching

For display settings using multiple LED panels, the video processor provides edge blending and image stitching capabilities. This helps create a seamless visual effect between different panels, ensuring smooth image transitions and a more harmonious overall display.

LED video processor control steps

Why are LED video processors essential?

Without a dedicated video processor, an LED display would not be able to efficiently handle input from various sources. Here are some reasons why LED video processors are indispensable:

Better image quality

Ensure that the video displayed on the LED screen is clear, vibrant, and aligned with the screen resolution.

Flexible input

Can connect and process multiple video sources, eliminating the need for multiple devices.

Synchronization

Ensure that the display of different panels remains synchronized, providing a smooth and consistent viewing experience.

Content management

It provides advanced content management capabilities such as multi-window display and real-time updates.

Video Processor

Conclusion

In conclusion, an LED video processor is a key component in any LED display system. By handling signal conversion, scaling, color correction, and synchronization, the video processor ensures that content is displayed on the screen in the best quality. Whether setting up a large outdoor LED screen or a small indoor LED display, choosing the right video processor can significantly impact the performance of the LED display.

Understanding how these processors work will not only help maintain a high-quality visual experience, but also ensure the efficient and reliable operation of LED display systems.

Composition of full-color LED screen

Introduction:

In a city, whether it is a large city or a small and medium-sized city, we can often see LED full color screens. Especially in urban commercial centers, whether in or outside shopping malls, tall LED full color screens are everywhere, and have even become a symbol of the city center. Because of this, more and more people want to know about full color LED screens, because it is crucial to choose what kind of media to promote their brand or service. Therefore, this article will introduce the composition of the full color LED screen in detail, and explain how its various components work together to create a colorful dynamic display effect.

Outdoor full color LED display

What is a full color LED screen?

The full color LED screen is made up of many individual modular LED displays. Since LED displays can be seamlessly spliced, the entire large screen looks like a whole, and each LED display is composed of LED modules, control systems, LED cabinets, power supplies, and electronic components. Cabinet materials include iron, aluminum, die casting aluminum, magnesium alloy, carbon fiber, etc. Among them, iron and die-cast aluminum are the most commonly used LED display cabinets. LED full color screens are widely used in advertising, stadiums, and stage events. Their high brightness, bright colors, and energy-saving characteristics make them ideal for indoor and outdoor use.

Modular LED displays

Composition of a full color LED screen

The composition of a full color LED screen can be divided into several key components:

LED module

Each LED module consists of multiple pixels, which are usually arranged in a grid. Each pixel contains three LED diodes – red, green, and blue. By mixing the three main colors of light with different brightness, a full color display is achieved. The resolution of the LED screen depends on the size and number of pixels in each module, which also affects the sharpness and quality of the image.

LED display cabinet

Control system

The control system is the heart of an LED display. It receives input from a video source such as a computer, media player or camera and processes the data to determine the color and brightness that each pixel should display. Advanced control systems are usually divided into synchronous control and asynchronous control, which can enable real-time adjustments and dynamic content updates.

Power supply

LED screens require constant power supply to maintain brightness and performance. High-quality power supply units (PSUs) are essential for stable operation and energy efficiency. PSUs convert the input voltage to the specific requirements of LED modules.

LED display cabinets

The LED modules are installed in the LED display cabinet, which acts as a structural frame to hold multiple modules together and protect the modules and wiring from environmental factors for easy maintenance. For larger LED displays, multiple cabinets can be spliced together into a seamless display.

Heat dissipation system

LED displays generate heat during continuous operation, so an effective heat dissipation system is important to prevent overheating, which can affect the display and shorten the lifespan of components. Many high-performance screens are equipped with fans or heaters to keep the system cool.

How to generate color on LED screens

The full-color LED screen produces colors through additive color mixing. Each pixel combines red, green, and blue LEDs at varying intensities to create a specific color. For example:

RGB full color LED screen

When all three LEDs are at full brightness, they produce white light.

When only red and green are illuminated, the pixel appears yellow.

By adjusting the brightness of each LED diode, any color in the visible spectrum can be achieved.

Advantages of full color LED screen

Full-color LED screens offer many advantages:

Brightness and Visibility: These screens are bright enough for outdoor use, even in direct sunlight.

High Contrast and Color Quality: LED technology provides vivid colors and sharp contrast.

Long Lifespan and Durability: LED displays are energy-efficient and durable, with a longer operational lifespan than many traditional display technologies.

Full color LED display applications

Due to its versatility and influence, the full color LED screen is widely used in a variety of applications, including:

Advertising billboards: Large LED screens attract attention with high resolution visuals, ideal for outdoor advertising.

Stadiums and arenas: LED screens display live action shots and scores in real time.

Stage and Event Backgrounds: Concerts and events use LED screens to create dynamic, immersive backgrounds.

Conclusion

Under the current economic conditions, the application field of full color LED screen is extremely broad. According to its application field, it can be divided the into outdoor LED full color dispaly and indoor LED full color display.

Outdoor full color LED display: Due to the long distance of outdoor viewing, LED displays with a large pixel pitch (e.g. P10, P8, P6, P5, etc.) are usually selected, so that there is no grainy feeling when viewing.

Indoor full color LED display: In general, indoor viewing distances are relatively close and the size is relatively small, so it is more appropriate to choose a small-pitch LED display.

By knowing the details above about full-color LED screens, we can gain insight into why they are so popular in today’s industries. Whether in advertising, entertainment or public information, these screens continue to change the way we experience digital content.

Regarding Programmed DOOH

The outdoor advertising industry has existed for more than a decade. From the age of billboard advertising to digital out-of-home today, the industry has been evolving constantly to tackle ever-changing consumer behaviours. One of the latest innovations in the industry is the programmatic DOOH or pDOOH. But what exactly is it?

In this beginner guide, we will dive into some important topics about programmatic DOOH. What is programmatic DOOH? What are the benefits of using it? And how does it work?

Programmatic DOOH

What is DOOH?

To explain what exactly programmatic DOOH is, we will have to look at what is DOOH first.

DOOH or digital out-of-home is a form of outdoor advertising which uses digital technology to deliver content to people in public places.

Unlike traditional out-of-home (OOH) advertising which uses static billboards and displays, DOOH advertising utilizes digital screens such as digital billboards, digital signages, video walls, and digital kiosks.

The usage of digital screens allows a more flexible content delivery which supports a wide range of digital media formats such as videos, images, texts, and animations.

The biggest difference between traditional OOH and DOOH is that OOH is used to display only a static advertisement at one time, whereas DOOH can be used to display multiple advertisements.

In short, DOOH makes both ads rotating and scheduling possible. Advertisers are no longer needed to run their ads 24/7. Instead, they can now reach their target audiences more effectively by running ads at the most suitable time periods.

Programmatic DOOH for Digital Billboard

What is Programmatic DOOH?

Programmatic DOOH (pDOOH) is an upgraded form of DOOH advertising where the process of media purchasing is becoming more convenient.

For both OOH and DOOH, advertisers or business owners will need to contact the billboard owners directly to purchase any media spaces. Besides, many other details such as content delivery, content schedule, and content formats are needed to be discussed and arranged personally with the billboard owners.

The purchasing process can become tedious especially when the advertiser has a huge number of advertisements or campaigns to run. Things can get complicated too if there are too many different locations and media owners involved.

Programmatic DOOH provides a single online platform where the buying and selling of digital ad spaces are automated. Besides, advertisers can also buy spaces only when their specified conditions are met. For example, a workshop that sells weatherproof tyres will want to display its advertisements only when there are rains in the targeted locations.

How Programmatic DOOH Works?

Programmatic DOOH provides high flexibility in running your outdoor campaign. The very first thing you need to do is to look for a reliable and trustworthy programmatic DOOH platform.

The programmatic platform acts as a middleman in the media purchasing process. It helps to connect media owners and media buyers conveniently.

Media buyers do not need to get in touch directly with the media owners. Instead, buyers only need to bid, upload content, and set up what they want to do or buy via the platform’s user interface. This is what we called a Demand Side Platform (DSP).

Demand Side Platform is a platform where media buyers can specify the number of spaces, the targeting locations, the desired publish date or time, and other unique conditions such as weather conditions and foot traffic.

Once the media buyers have placed their bids, the platform will then communicate to a Supply Side Platform (SSP). SSP is a platform where media owners manage their advertising inventories or ad spaces from all kinds of digital screens.

When there is any advertising slot that meets the requirements of the media buyer, a transaction will be made if the bid is won. The media buyer’s advertisements will be then published automatically.

Benefits of Using Programmatic DOOH

Programmatic DOOH makes everything looks so easy and convenient. It offers some benefits to businesses and advertisers that other platforms or channels cannot offer.

Some of the mentionable benefits of using programmatic DOOH are

  1. Run your campaign faster.
  2. Data-driven campaign.
  3. Flexible platform.
  4. Reduce human error.
  5. Transparent and competitive pricing.

Run Your Campaign Faster

Running an outdoor campaign is so much easier with programmatic DOOH. Unlike traditional outdoor advertising which could take up to days or months to deal with the media owner and to wait for available spaces, securing ad slots is so much faster with pDOOH.

As long as you have a laptop, a computer or a smartphone with an internet connection, you can run your campaign with just a few clicks. Uploading and updating content can be done easily too.

Data-driven Campaign

Data is extremely important for any business. Same goes to the outdoor advertising campaign. You will want to run your campaign with some specified goals. You will want to achieve the best possible outcome by making the correct decision.

To make correct decisions, using external data in your campaign is a great idea. Data analysis can be hard to implement in traditional advertising campaigns. However, since programmatic DOOH uses various digital technologies to gather audience data and demographics, it is possible to offer highly personalized and engaging experiences to your target audience.

Some of the external data that can be utilized are traffic volume count, age, gender, dwell times, temperature, and weather conditions. All these data can be collected by the DOOH networks via sensors, cameras, and mobile location data.

For example, if you are promoting cosmetic products, you might want to find an ad space that is located in a crowded area where there are more women than men.

Programmatic DOOH uses a data-driven approach to help businesses to do better with their targeting. Besides, pDOOH can also help to measure campaigns’ performance by collecting data such as impressions, footfall traffic, and dwell time.

DOOH Data Advertising

Flexible Platform

Programmatic DOOH is highly flexible in many areas. Technically, advertisers are free to set any criteria or requirements to target their audiences more effectively. The advertisements will only get triggered when their specified requirements are met.

Besides, pDOOH has pushed location-based advertising to its next level. There are many digital screens in multiple locations in a city, and pDOOH makes all of them easily accessible. No matter who are the media owners behind all these digital screens, ad space purchasing of different locations can be done within one single online platform.

In addition to the two flexible areas mentioned above, programmatic DOOH also offers flexibility in terms of cancellation policy. You can always pause, update or stop your campaign anytime you want. Advertisers are not tied to complicated contracts when they buy ad spaces via pDOOH.

Reduce Human Error

Programmatic DOOH helps to automate many tasks online. From choosing ad space to online payment, not much manual work is involved. When there is less manual work or fewer parties involved, human error can be reduced greatly. In short, pDOOH helps businesses to deliver content effectively with utmost accuracy.

Transparent and Competitive Pricing

The programmatic DOOH platform is an exchange where media buyers and owners gather together. To attract media buyers or advertisers, media owners will have to display their best prices on the platform.

This level of transparency is definitely one of the biggest advantages to media buyers. Buyers can now compare different pricing plans and make the most suitable decisions.

The transparent and competitive environment also encourages media owners to focus on providing the best services, which will ultimately benefit the media buyers in the end.

The trend of outdoor LED display screens

Technology keeps changing and evolving, and the same goes to consumer’s expectations. As with any digital display, consumers are looking for sharper, brighter, lighter, higher quality and cheaper-to-maintain LED screen display for outdoor applications. We have studied and gather 7 key trends of outdoor LED screen display.

Outdoor LED Billboard

1. Higher Screen Display Resolution

Outdoor LED screen usually has a large pixel pitch of 10mm above. However, with matured manufacturing processes and extensive R&D budget, we are getting fine pixel pitch as narrow as 2.5mm which is in the realm of indoor LED display territory. This enables outdoor LED screen to be visually sharper and have more detailed images. Such high-density outdoor LED screen provides new applications in areas with close viewing distance while requiring the robustness and waterproofing capability of outdoor LED screen.

2. 3D Outdoor LED Screen

3D LED screen is a display technology that combines the use of 3D rendered animated videos and specially shaped LED screen display to create the illusion of three-dimensional images, all without the use of professional 3D glasses. The most popular shape employed for 3D LED screen is an L-shape, where there will be two sides of rectangular outdoor LED screens join together at around 90 degrees angle. Several key landmarks and malls around the world have employed such design for the outdoor LED screen. Normal 3D Outdoor LED screen uses flat module design with a right-angle joint that resulted in a black line that separates both sides of the display. Nowadays, new technology enables seamless outdoor LED screen by using a special design outdoor LED cabinet panel that wrap around the corner smoothly without any pixel loss.

Glasses-free 3D LED Screen

3. Fully Front Accessible

Generic outdoor LED screen typically requires a service platform at the rear for the ease of service and maintenance. It is a general perception that outdoor LED screen display is thick and bulky due to the rear service requirement. However, some applications call for front accessibility and slim display screen design.  In such cases, outdoor LED screen with fully front service capability is demanded. LED module, switching power supply unit and LED receiving card can be replaced from front by using simple tools in a true fully front accessible design of an outdoor LED screen. Therefore, the profile or the thickness of a front accessible outdoor LED screen can be as little as the LED cabinet panel thickness plus the single layer of mounting bracket. A fully front accessible outdoor LED screen can have a thickness ranging from 200-300mm, while a rear accessible outdoor LED screen have a thickness ranging from 750-900mm.

4. Lightweight Design

Traditional outdoor LED screen uses steel metal plate due to the ease of customization and low cost. The main drawback of using steel material is weight issue, which is a disadvantage for any weight sensitive application such as cantilever or hanging outdoor LED screen. A thicker and sturdier structure design is required to support a heavy outdoor LED screen, elevate the weight issue further. Therefore, one of the key trends of outdoor LED screen is to use lightweight material such as aluminium alloy, magnesium alloy or even carbon fibre. The most cost-effective option of the three options above is aluminium alloy, which allow for great weight saving over steel material and cheaper compared to magnesium alloy and carbon fibre.

5. Fan-less Operation

By using aluminium alloy extensively in the outdoor LED screen design, heat dissipation level increases over traditional steel material. This enables fan-less design, which reduces energy and noise level, and remove the inherited mechanical issue of ventilation fans. Hence, a fan-less outdoor LED screen is suitable for applications that require silent operation and green sustainability design. The only moving/mechanical part in an outdoor LED screen is ventilation fan, which has a definite lifespan and will breakdown over time. Fan-less outdoor LED screen eliminate this potential breakdown altogether.

6. Superior Weather Resistance

A traditional outdoor LED screen has an IP rating of IP65 for the front display area and IP43 for the rear area. The IP rating difference is because of the fact that traditional outdoor LED screen requires opening vents for the cooling ventilation fans to cool down the LED screen’s internals. The active ventilation design inherits another problem which is dust accumulation within the outdoor LED screen cabinet. Therefore, some manufacturers suggest to install an aluminium enclosure to the outdoor LED screen with air-conditioners to mitigate the problems above. This increases carbon footprint and operation costs because air-conditioners and fans require periodic service and maintenance. New outdoor LED screen such as Big Outdoor S series features all aluminium LED module design that enables IP66 rating on both front & rear surface of the outdoor LED screen without any mechanical part. The switching power supply unit and LED receiving card are also fully enclosed in an aluminium compartment with heatsink design. This enables the outdoor LED screen to be installed in any venues with harsh operating environments.

7. Lower Operation & Maintenance Costs

After years of LED screen development in the industry, a new LED driving method known as common-cathode has emerged to reduce the energy consumption by as much as 50%, compared to common-anode LED driving method. Common cathode refers to the method of supplying electricity to individual Red, Green and Blue chips of the LED screen. This is especially useful for outdoor LED screen where high power consumption is required for high brightness output for visible images under bright sunlight. Outdoor LED Screen such as MuenLED Outdoor S series can be specified with this common cathode LED driving method to reduce the energy consumption. Therefore, the operation & maintenance costs can be further lowered, improving the return of investment (ROI) and high screen uptime availability for advertisers.

Conclusion

Display technology of Outdoor LED screen keeps on evolving in accordance to market needs. Unlike indoor LED screen, outdoor LED screen design requires proper consideration of shape, resolution, front or rear accessibility, weight, energy consumption, operation and maintenance costs. Selection of a good outdoor LED screen product is essential to the success of a digital display investment. A properly designed product like Big Outdoor FPro series guarantees long lasting display performance with a peace of mind product ownership.

Skills for designing outdoor digital billboard LED display screen content

Digital billboard is a digital display that helps businesses in reaching a target audience effectively. While a digital billboard offers many advantages that most traditional displays cannot provide, the digital display itself does not guarantee a successful digital campaign automatically.

It is true that a digital billboard is a powerful tool. However, a powerful tool can turn useless if it is not being used wisely and skilfully. The content and the business strategy are more important than the tool.

Digital Billboard

Digital billboard is all about content. It is nothing more than a meaningless giant screen if the content is not legible or attractive enough.

In this article, we will look at the 10 tips on designing the most effective content for a digital billboard campaign.

  1. Use contrast colours.
  2. Highlight only one or two main messages.
  3. Use large bold, and easy-to-read typefaces.
  4. Use a limited amount of texts and elements.
  5. Use visual priority in your composition layout.
  6. Use visual cues to direct attention.
  7. Avoid white backgrounds.
  8. Use the right images.
  9. Play with creativity and imagination.
  10. Test your content.

1. Use contrast colours.

Digital billboard content is all about legibility. Legible content is content that is being clear enough to read from a far distance. Using contrast colours can help to make your content easier to read.

Using contrast colours is about achieving the best colour combinations. Normally, white can work well with dark colours while black can be used together with brighter colours. According to the modern colour theory, contrast can be achieved using complementary colours – the two colours which are on the opposite sides of the colour wheel.

Another reason for using contrast colours is to separate your main elements or artworks from the content background. If your artworks or texts are filled with non-contrasting colours, your elements will fail to stand out. As a result, the audience cannot focus on your main messages.

Color Combination for Digital Billboard Content

2. Highlight only one or two messages.

While digital billboards can display video content with a longer duration compared to images or static advertisements, you still want to aim to relay your message in the shortest possible time.

Attention span is getting shorter nowadays. It is always better to keep your audience informed and to understand your message with just a single glance. Another reason is that digital billboards are always targeting a moving audience outdoors. Your audience could be boarding a moving train or driving a car. They have only few seconds to notice and read your content while moving.

Whether it is an image or video content, you need to identify what is the most important message you want to deliver. What is your call to action? How can you include your call to action and message as simple as possible in your content?

For example, if you are displaying an advertisement on a digital billboard next to a highway, do you think it is a great idea to include a phone number in your content?

Always remember to keep things simple. Simplicity is the best way to deliver meaningful content.

Digital Billboard Content

3. Use large, bold and easy-to-read typefaces.

An easy-to-read typeface is one of the most important legibility factors. Your audience can be viewing your content from a very far distance. You should always use a text height of at least 20 inches for a headline. Body text can be kept at a height of 12 inches. However, never use any text height that is shorter than 4 inches. It is extremely hard to read small texts at a long distance.

Typography is a design principle that will determine whether your text is easy to read or not. An easy-to-read typeface depends greatly on its arrangement, styling, and spacing.

While we are not going to give a detailed lecture on typography here, there are some simple guidelines that you should follow when designing digital billboard content.

  1. Use bold fonts. Avoid thin and fine strokes as they will become less obvious at a long distance.
  2. Long sentences with all capital letters are hard to read.
  3. Close letterspacing is hard to read.
  4. Avoid using too many different types of fonts.
Typeface

4. Use a limited amount of texts and elements.

The audience has very limited time to read your content. Keep your content simple by using lesser texts and elements. A headline should be kept at 7 or fewer characters.

If you are displaying video content, each shot should be kept as simple as possible. Avoid cluttering your content with too many images or graphic elements.

For example, Apple used only a photo captured by its iPhone to highlight its core message. A single image is sufficient enough to tell the audience that its iPhone has a superior camera performance.

LED Digital Billboard

5. Use visual priority in your composition layout.

You could be using images, texts, and graphic elements in your content. However, if you are having too many elements within your content, the audience might have a hard time determining which element is the most important information. They do not know how to move their eyes across the content – where and which element to look at first.

Using visual priority can provide a sense of hierarchy in your content. Normally, you will want your most important message to appear as the largest element within your content. Less important elements such as terms and conditions should be kept smaller when compared to others.

Humans read and scan lines from top to bottom. Hence, always put the more important elements or messages on the top of your content.

6. Use visual cues to direct attention.

There are times when you need to disobey the visual priority rules and place your most important messages somewhere else due to some design factors. You can use visual cues in this situation.

Visual cues or directional cues are elements that can help to direct attention to important areas such as call-to-actions, products and main messages. Some of the most common cues are arrows, face or eye direction and colour contrasts.

Visual cues are important. If your design sucks, the audience can never pay attention to your message effectively even though you have the greatest content in the world.

Digital Billboard Content with directional cue

7. Avoid using white backgrounds.

Digital billboards are made up of multiple LED screen panels, and these LED screen panels contain many tiny LED bulbs or packages. Most LED bulbs or packages come in three colours – red, green and blue.

All red, green and blue LEDs need to be turned on to their maximum brightness levels to produce white lights. As a result, the power consumption of the digital billboard is increased greatly.

Besides, a full-white background can appear very bright especially at night. A bright background can make your content hard to read. Moreover, it can also distract road users.

8. Use the right images.

An image is powerful enough to tell a story. Some even agree that image is a lot more effective than texts and other elements in engaging audiences. Thanks to the vivid display screen of digital billboard, vibrant and colourful images can capture attention easily.

When using images in your content, always pick the images that can tell your message effectively. Avoid using images for decorative purposes. It is meaningless to clutter your content as audiences have very limited time reading your screen.

9. Play with creativity and imagination.

One of the reasons that businesses are switching to using digital billboards is the ability of the digital screen to display a wide range of digital media formats. Some of the supported media formats are videos, texts, images, and animated graphics.

Unlike traditional billboards which creativity can be limited, you can choose to display almost anything that you want by using the digital billboard. Find the best format that suits your business nature and engage your audience in the best possible way.

For example, businesses are now using digital billboards to display glasses-free 3D content. The content is usually targeting pedestrians in busy areas with heavy foot traffic. The 3D content can provide an exciting viewing experience, and it is so unique that pedestrians are willing to stop what they are doing to watch the content.

10. Test your content.

Buying an advertisement space or slot can be expensive. A poorly-planned content can ruin your digital billboard campaign.

Although you have followed all the basic guidelines and have been working hard to create the best ever content you can come out with, it is still crucial to test your content before launching your campaign.

Get some friends or outsiders. Show them your content and ask for their opinions. You can simulate the real-life situation by showing the content for not more than 5 seconds. Then, check with your friends how well they can understand your message.

Digital Billboard & Outdoor LED Display

Conclusion

Digital billboard is an effective tool in outdoor advertising or digital out-of-home (DOOH). The right tool is crucial in producing great work, but how you use the tool is important too. With the right digital billboard design and content, you can improve the effectiveness and ROI of your digital campaign.

What are the precautions for using LED display screens?

Introduction:

LED display is complex system engineering. It is not only necessary to strictly control the quality of the production and manufacturing process, but also to pay attention to many details in daily use to ensure its long-term stable operation and prolong its life. If these precautions are ignored, the LED display may not work properly, and may even cause major safety hazards, such as damage to parts or fire. This article will explain the precautions in the use of the LED digital screen in detail, from environmental requirements to power supply specifications, to cleaning and maintenance, so that your equipment can operate more safely and efficiently.

LED digital display

LED digital screen usage environmental considerations

The working environment temperature range of LED digital display screen is from -20℃ to 50℃, and the humidity range is from 10% to 90% RH, but you must avoid using it in high temperature, high humidity or corrosive environment. When placing and installing, keep the LED screen body away from flammable objects, dust and other dangerous sources, and avoid violent collisions or contact with sharp objects. When installing and using the screen, you must ensure that the LED screen body does not enter the internal water, iron powder and other conductive substances. If it accidentally enters the water, you must immediately disconnect the power supply and wait until it is completely dry before using it again. In addition, under poor heat dissipation conditions or high temperatures, it is recommended to avoid opening the screen for long periods to avoid damage to parts.

Outdoor advertising LED screen

LED digital screen power supply considerations

LED digital displays on the power supply requirements are very strict, the LED module must use DC+5V power supply (operating voltage 4.2~5.2V), and the polarity of the power supply ends can not be connected to the reverse, otherwise it will burn the equipment or even cause a fire. The power supply voltage should be maintained at 220V ± 10% and the frequency at 50hz ± 5%, and ensure that the ground contact is good, and avoid sharing the power supply with high-power equipment.

The power supply of the equipment should be carried out step by step so that the maximum power of the entire screen does not affect the power distribution system. When using the LED screen, it is recommended that you play dynamic video and avoid displaying an all-white screen with high brightness for long periods of time to avoid overheating the power cord or damaging the lamp bulbs.

Maintenance of LED display

Switching LED screen operation precautions

When switching on and off the LED screen operation, it should be carried out in the order of switching on the computer first and then switching on the screen, and switching off the screen first and then switching off the computer.
