Advantages of Flexible LED Screens

In the past, all the LED displays we were familiar with were rigid. It seemed impossible to combine the word “soft” with electronic displays, but the emergence of flexible LED screens broke this perception. Unlike traditional LED displays that use rigid PCB boards such as glass fiber materials, LED flexible screens use flexible FPC circuit boards, and use rubber materials to make masks and bottom shells, and cooperate with a series of special designs such as special locks and link devices, to ensure the degree of flexibility of the LED display to complete the bending shape that other ordinary screens cannot achieve.

 

 

Advantages of LED flexible screens

In addition, in the past, the traditional LED display screen was fixed with screws and frames, and other large-scale installation methods, while the installation method of the LED flexible screen is as simple as sticking a piece of paper on the wall. Due to its very light weight, LED flexible screens are mostly installed by magnet adsorption and pasting methods, which simplifies the installation and disassembly process, allowing customers to easily complete the installation work by themselves, which greatly reduces the burden of use.

Such characteristics make it easier to use LED flexible screens when facing some irregular and special positions such as curved walls and columns, which are difficult for traditional LED displays to fit perfectly. If the usual LED display is to be installed on a curved wall, there are generally three methods: make the cabinet into a vertical strip and install it spliced; make the cabinet into a curved one and then splice it; make a special unit, and the screen steel structure also needs to be made into a curved shape. These three methods are undoubtedly very troublesome in production and installation, while LED flexible screens are more convenient in comparison. In view of the above characteristics.

Common application scenarios

The common application fields of LED flexible screens are also places with special shapes, such as shopping mall columns, bars, stages and so on.

In addition to the above, flexible LED screens have more advantages such as single-point maintenance, seamless splicing, and high efficiency and energy saving, which are not available in traditional LED displays.

Although the current LED flexible screen is still not perfect, we have reason to believe that with the development and improvement of technology and technology, the technical problems of LED flexible screen will be overcome, and the market “blue ocean” of LED flexible screen will become very impressive.

Functions and features of automotive LED displays

The vehicle-mounted LED display screen is a product that uses LED technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, vehicle-mounted electronic technology, etc. to display information on mobile cars. Because it is based on mobile buses as a medium, it can be widely circulated in many places, bringing great advertising and promotion effects, and is widely accepted. It is different from ordinary LED displays installed in fixed places. The reason is in-car and advertising.

Features of car LED display:

High stability and reliability

The car is always moving, and every time it brakes, starts to turn, there will be some weak pulling force, so the vehicle-mounted LED display has high requirements for the stability and reliability of electronic products.

Stable power system support

The power supply in the car is powered by the battery. Similarly, when the car starts, brakes, and stops, the power supply voltage will be temporarily unstable. If the power supply system is not good, the display screen will be burned.

Wide operating temperature range

In the north, cars are usually placed outdoors. The temperature may reach -40°C in winter and 60°C in summer, which requires power supply and display components to work in a wide range of temperatures.

 

 

Good anti-static measures

Cars are prone to generate static electricity during operation, especially in autumn. The static electricity high voltage can reach thousands of volts. If there are no good anti-static measures, sparks can easily damage ICs and LED lights.

Suitable brightness

Appropriate brightness. If the LED display screen is not bright enough, it will not be visible during the day and the meaning of installing the display screen will be lost; if it is too bright, it will affect driving.

LED brightness attenuation

This is a common feature of LED products. LED attenuation characteristics: LED brightness is attenuated, with a 10-70% attenuation rate in a year. If the quality is poor, the brightness will be reduced by half in half a year, making it impossible to see the display content clearly.

Good promotion

Buses and other means of transportation can be said to be everywhere in the city, so their advertising effect can also affect the entire city, thus bringing great publicity effects to products and services.

How are indoor LED displays installed?

To install an indoor LED display, the commonly used method is to buy frames, modules, cables, power supplies, control cards and other materials to assemble the LED display by yourself, so how to assemble the modules into a whole large LED screen , and use it normally? The installation steps are explained in detail below.

Indoor LED Display

Let’s take the 4800mm*1920mm LED display as an example

First calculate the size:

The size of the full-color modules used in the unit board is 320*160mm, 15 pieces long and 12 pieces high. This color screen shares 180 modules. 320*15=4800mm, 160*12=1920mm,

The net area is 4800mm*1920mm plus 10mm extra head (2mm is used to remove the stainless steel package, and the joint between the board and the frame is 5-8mm. The upper and lower heads can be left on the top and cannot be seen from the front), frame size It is 4810mm*1930mm.

1. Make the border

Make a structure based on an example of an existing small screen that is being produced. Buy 4 pieces of 4*4 square steel and 4 pieces of 2*2 (6 meters long) from the market, first use 4*4 square steel to make a field frame (can be customized according to your own situation), the size of the large frame is 4850mm*1970mm, because the size inside the small frame is the size of the screen, and the square steel is 40mm, so it is this size.

When welding, use a steel square to weld a 90-degree angle as much as possible. The size in the middle doesn’t matter. After the cross-shaped frame is completed, start to weld small square steel on it. The internal size of the small square steel is 4810mm*1930mm. The four corners and the middle part are cut into small pieces with the remaining 4*4 square steel and welded on to facilitate the cladding of stainless steel.

After the small connecting frame is completed, start to weld the back strips. Use the plate to measure and weld the first two pieces. After finding the size, you can weld all the way down. The back bar is 40mm wide and about 1980mm in length, just weld both ends. The welded frame (the back is pictured) can be installed in the hall. Make two angle steel hooks on the top of the wall.

2. Install power supply, control card and module

After the shelf is hung, leave a gap of about 10mm around, because the indoor screen cannot be made into a box frame with a fan, and only the gap of 10mm can be used for simple ventilation. When installing the power supply, first connect the two finished power cables. The positive and negative poles of the 5V output must be optimistic, otherwise the power cable, module and control card will be burned. Each finished power cord has two connectors, so that each power supply can carry four modules. Then the power supply is connected by 220V. Use 2.5 square annealed copper wires to string each row together. Finally, a set of 220V power cables is connected to the open terminal of the power distribution cabinet. The cables from the power distribution room to the LED display power distribution cabinet must be arranged before the screen is installed. After the power supply is connected, the control card is installed. The control card here uses a synchronous receiving card. For the layout of the entire power supply and control card, the LED display has a “Power Supply and System Wiring Diagram” before leaving the factory. As long as the wiring diagram is strictly followed, there will be no mistakes. General engineers themselves can also estimate the wiring method based on the number of power supplies and cards.

3. Connection between receiving card and module

Here, each card has three columns of modules, a total of 36 boards, so that one card is installed in every three columns, and the card is powered by 5V from the nearest power supply. Pay attention to the positive and negative poles, and then connect the five cards with a network cable. , the network port next to the power connector is the input port, the right is the first card, which is also the head card, the input is connected to the Gigabit network card of the computer, and the output network port is connected to the input port of the second card, the second card The output port of the card is connected to the input port of the third card, so until the last card, the fifth card, the input is connected to the output of the fourth card. The output port is empty.

4. Stainless steel edging

Stainless steel edging is required before installing the module. This is just for good looks. Some customers also require it to be installed. When doing stainless steel edging, increase 5mm according to the size of the steel structure. The purpose is to facilitate the installation of stainless steel edging and prevent it from being stuck. Stainless steel edging. Here, because the size of the screen is small, we installed the stainless steel edging in advance, and sometimes the stainless steel edging can be installed after the screen is installed, but it should be noted that the first row at the bottom must be level.

5. Install the module

After buckling the stainless steel side, start to install the module. The normal sequence of module installation: install from the bottom to the top or from the middle to both sides. There are also many controversies about this installation method. The main purpose of installing from the bottom is to keep the horizontal and vertical within the normal control range, especially when the screen area is large, it is easier to get out of control, especially the requirements for small spacing are higher, and there is a little gap If the requirements are not met, fine adjustments are required. Engineers who have installed small pitches know that even if the precision mold comes out of the module or box, there are still errors. The misalignment of a few wires will lead to the misalignment of the entire row.

Secondly, the installation from the middle to both sides can be divided into two groups or even four groups of people to divide the work and save installation time. Even if there is a problem of installation dislocation, it will basically not affect the progress of the other group of personnel.

If there is any problem, solve it in time, because if you install another set, it will cover this card and cannot be tested. In addition, if you continue to install, you will not be able to find the problem in time. If all are installed Then, to find the problem, and remove the installed modules, the amount of work will be much larger.

There is a test button on the control card. You can use this method to test first when the power is on.
