10 ways to recognise the quality of an LED screen

How to Identify the quality of LED screen？

With the development and progress of science and technology in the society, the application range of LED screen is getting wider and wider. At the same time, the number of LED display suppliers is also increasing. This also means that the quality of LED screen varies greatly, and accidents of poor quality LED display screen often occur. So, when we are buying LED display, how do we judge its quality? This article will provide 10 methods for your reference.

1. Brightness and viewing angle

Generally speaking, the brightness of indoor full-colour LED screen is around 800-1200nits, and the brightness of outdoor full-colour LED screen is around 4000-6000nits. Such brightness range is suitable for the brightness of the display in different environments. However, for the LED display screen, not the higher the brightness adjustment the better. Display brightness is too high will not only cause discomfort to the human eye, but also reduce the service life of LED lamp beads. The viewing angle is mainly determined by the encapsulation of the wick module. The size of the viewing angle directly determines the audience of the display, so the bigger the better.

2. Contrast ratio of LED screen

LED display screen contrast ratio measures brightness contrast between brightest and darkest areas, indicating the screen’s ability to produce varying levels of brightness and darkness and reflect depth of field and picture level details. A whitish grey screen with low transparency signals a low contrast ratio. Contrast ratio is typically expressed as a ratio, such as 1000:1 or 5000:1. Higher contrast ratio results in clearer images and brighter colours, while lower contrast ratio results in blurrier images and more muted colours.

3. White balance and colour temperature

White balance and color temperature are crucial parameters in the adjustment of LED screens, which directly affect the accuracy and authenticity of the display effect. The correct white balance can ensure that the displayed white is not biased, pure, and consistent under different brightness. In LED screens, the tone and atmosphere of the overall display screen can be changed by adjusting the color temperature.

4. Uniformity of LED screen

Uniformity refers to whether the LED screen is clean and free of pits and mosaics, and is mainly related to the consistency of LED light brightness and colour. Improving uniformity helps to improve the overall visual impact and viewing experience. Commonly used technical measures include point-by-point correction and backlight uniformity design.

5. Refresh rate of LED display

Refresh rate refers to the number of times per second the LED screen updates the screen, the unit is Hertz (Hz). A high refresh rate can make the dynamic image smoother and reduce drag and blur. Generally speaking, the refresh rate of high-end LED display can reach 1920Hz or even higher.

6. Whether there is a colour block

LED screen colour block refers to the module display and the normal area there is a significant colour difference. The colour transition is based on the module. The phenomenon of colour block is mainly caused by the poor quality of the display circuit board, the poor quality of the IC chip and the unqualified welding process.

7. Square power consumption

The square power consumption refers to the power consumption generated by the LED screen with an area of 1 square meter. The unit is watts. We usually say that the unit of electricity is W/H. The power consumption of LED displays generally has two indicators, one is the maximum power consumption and the other is the power consumption. The maximum power consumption refers to the power consumption of the LED screen at the maximum brightness. The power consumption refers to the power consumption when playing advertising videos, text and pictures. Lower power consumption means lower cost of use and less heat. The generation of heat depends on the current, which directly affects the service life and stability of the display.

8. Reliability of LED display

Reliability refers to the ability of an LED screen to maintain normal operation during long-term use. Methods to improve reliability include using high-quality LED chips and driver circuits, optimizing heat dissipation design, etc. Generally, you can determine the number of times the screen appears during aging by asking the manufacturer for aging records.

9. Packaging and transport

LED screens are valuable items, both in value and weight. The packaging method used by the manufacturer is very important. In general, the box is packed in a single box, and each side of the box should have a protector to cushion. There is little room for movement inside the box during transport. The outer box must be clearly labelled.

10. Safety of LED screen

LED screen consists of multiple modules. Each LED module must be equipped with external grounding protection, and the grounding resistance should be less than 3 ohms. Can withstand 1500V high voltage without breakdown for 1min. Warning signs and slogans should be installed at the high voltage input port and high voltage wiring of the power supply.

conclusion

In summary, through the above 10 aspects, we can identify the quality of LED displays. When we look at apiece of LED display, we will know from which aspects to identify its quality level, so as to achieve the purpose of choosing cost-effective products that suit you.

It is a technology widely used in the electronics manufacturing industry to package integrated circuit chips or other electronic components for direct mounting on the surface of a PCB (printed circuit board).

Main features of SMD Packaging:

Small size

SMD-packaged components are small in size, allowing high-density integration, which is conducive to the design of miniaturized and lightweight electronic products.

Lightweight

Since SMD package components do not require pins, the overall structure is lightweight and suitable for applications requiring light weight.

Good high-frequency characteristics

The short pins and short connection paths of SMD packaged components help to reduce inductance and resistance and improve high-frequency performance.

Easy to automate production

SMD packaging components are suitable for the production of automated placing machines, improving production efficiency and quality stability.

Good thermal performance

SMD package components are in direct contact with the PCB surface, which is conducive to heat dissipation and enhances the thermal performance of components.

Easy to repair and maintain

The surface mount of SMD package components makes it easier to repair and replace components.

Package Types

There are various types of SMD packages, including SOIC, QFN, BGA, LGA, etc. Each package type has its own specific advantages and application scenarios.

Technology Development

Since its introduction, SMD packaging technology has developed into one of the mainstream packaging technologies in the electronics manufacturing industry. With the advancement of technology and market demand, SMD packaging technology is also evolving to meet the needs of higher performance, smaller size, and lower cost.

COB (Chip on Board) Packaging

COB packaging technology, the full name of Chip on Board, is a kind of packaging technology that sells the chip directly to the PCB (Printed Circuit Board). This technology is mainly used to solve the problem of LED heat dissipation and realize the tight integration of the chip and circuit board.

Technical principle

COB packaging is to attach the bare chip to the interconnect substrate with conductive or non-conductive glue, and then perform wire bonding to achieve its electrical connection. During the packaging process, if the bare chip is directly exposed to the air, it is vulnerable to pollution or man-made damage, so the chip and bonding leads are usually wrapped with glue to form a so-called “soft package”.

Compact packaging

By combining the packaging and PCB, the chip size can be greatly reduced, the degree of integration can be improved, and the circuit design can be optimized to reduce circuit complexity and improve system stability.

Good stability

The chip is soldered directly to the PCB, so it has good vibration and impact resistance. It can also maintain stability in harsh environments such as high temperature and humidity, prolonging product life.

Good thermal conductivity

Using a thermally conductive adhesive between the chip and the PCB can effectively improve the heat dissipation effect, reduce the impact of heat on the chip, and improve the service life of the chip.

Low manufacturing cost

no pins are required, eliminating some complex connectors and pins processes in the manufacturing process, reducing preparation costs. At the same time, automated production can be realized, reducing labor costs and improving manufacturing efficiency.

Notes:

Maintenance difficulties

Due to the direct sale of the chip and PCB, it is impossible to disassemble or replace the chip separately, generally requiring the replacement of the entire PCB, which increases the cost and difficulty of maintenance.

Reliability dilemma

The chip is embedded in the adhesive, and the digestion process can easily damage the micro-dismantling frame, which may cause the lack of pads and affect the tendency to produce.

The environmental requirements are high

COB packaging does not allow dust, static electricity and other pollution factors in the workshop environment, otherwise it is easy to increase the failure rate.

In general, COB packaging technology is a cost-effective and excellent technology with broad application potential in the field of intelligent electronics. With the further improvement of technology and the expansion of application scenarios, COB packaging technology will continue to play an important role.

What are the differences between SMD and COB technology?

Visual experience

COB LED display, with its surface light source characteristics, brings a more delicate and uniform visual experience to the audience. Compared to SMD point light sources, COB has brighter color performance and better detail processing, making it more suitable for long-term close-up viewing.

Stability and maintainability

Although the SMD display is convenient for on-site maintenance, its overall protection is weak and easily affected by the external environment. The COB display has a higher level of protection due to its overall packaging design, with better waterproof and dustproof performance. However, it should be noted that in the event of a failure, the COB display usually needs to be returned to the factory for repair.

Power consumption and energy efficiency

Since COB uses an unobstructed flip-chip process, its light source is more efficient and consumes less power at the same brightness, saving users electricity bills.

Cost and development

SMD packaging technology is widely used in the market due to its high maturity and low production cost. Although COB technology is theoretically cheaper, the actual cost is still relatively high due to its complex production process and low yield. However, with the continuous advancement of technology and the expansion of production capacity, COB costs are expected to be further reduced.

Conclusion

Nowadays, in the commercial display market, COB and SMD packaging technology have their own strengths and weaknesses. With the continuous growth of high definition display demand, Micro LED display products with higher pixel density are gradually favored by the market. And COB technology has become one of the key technologies to achieve the high pixel density of Micro LED due to its high integrated packaging characteristics. At the same time, with the continuous narrowing of LED screen pitch, the cost advantage of COB technology has become increasingly prominent.
