At present, with the increasing consumption level of Chinese people, LED lighting has gradually been used in daily life of families. LED electronic displays not only enhance the image of the city, but also enrich people's cultural life. The development speed is so fast. While we enjoy the economic benefits of LED electronic screens, some businesses with LED electronic screens do not fully understand the precautions of LED electronic screen operation and use, which leads to shortening the life of LED electronic screens. Here, analyze the precautions for the operation and use of LED electronic displays to ensure the safe and normal operation of the LED display system! The development of LED display industry continues to increase, and the large LED screens on the streets of major cities are gradually increasing. .

First, matters needing attention when switching LED electronic display:

1. Switch sequence:

When opening the screen: power on first, then open the screen.

When turning off the screen: turn off the screen first, then turn off the screen

(Turn off the computer without turning off the display first, it will cause the screen body to appear bright spots and burn the lamp, with serious consequences.)

2. The interval between switching the screen should be greater than 5 minutes;

3. After the computer enters the engineering control software, the screen can be turned on.

4. Avoid opening the screen when the screen is completely white, because the system's inrush current is the largest at this time.

5. Avoid opening the screen when it is out of control, because the inrush current of the system is the largest at this time.

6. When the ambient temperature is too high or the heat dissipation conditions are not good, be careful not to open the screen for a long time.

7. When a line appears on a part of the electronic display, the screen should be turned off in time. In this state, it should not be turned on for a long time.

8. The power switch of the display screen often trips. Check the screen body or replace the power switch in time.

9. Regularly check the firmness of the joint. If there is looseness, pay attention to timely adjustment, re-reinforce or update the hanging pieces.

10． According to the environment of the large-screen display screen body and the control part, to avoid insect bites, rodent repellent should be placed if necessary.

Second, the control section changes, changes to note

1. The power cords of the computer and the control part should not be connected in the reverse direction. They should be plugged in strictly according to their original positions. If there are peripherals, test whether the case is live after connecting.

2. When moving control equipment such as a computer, check the connection wires and control board for looseness before turning on the power.

3． The position and length of communication lines and flat connecting lines cannot be changed at will.

4． If abnormalities such as short circuit, trip, wire burn, and smoke appear after moving, the power-on test should not be repeated and the problem should be found in time.

Three software operation and use precautions

1. Software backup: WIN2003, WINXP, applications, software installation programs, databases, etc. It is recommended to use 'one-click restore' software for easy operation.

2. Familiar with installation method, original data recovery and backup.

3.Master the setting of control parameters and modification of basic data presets

4. Skilled in using programs, operations and editing.

5. Regularly check for viruses and delete irrelevant data

6. Non-full-time personnel, please do not operate the software system.

As the development time of LED display screens increases and the application fields become wider, people's understanding and awareness of LED display screens will also deepen, and those who did not understand the problems before gradually show up. From a technical perspective, currently China's LED display technology mainly has the following problems:

First, the problem of insufficient brightness

The main advantage of the LED display is its strong adaptability to the changing and complex outdoor environment. The characteristics of the outdoor environment require that the LED display be adequate on sunny, cloudy, rainy and snowy weather, long distances and multiple viewing angles. Brightness is used to convey information, so brightness is particularly important. Due to the lack of LED brightness, LEDs can currently only play a supporting role in the lighting industry, mainly for decoration. This is a huge challenge for the comprehensive use of tens of thousands of LEDs.

Second, it is the problem of LED color difference

In the application of a single LED, there is basically no problem of color difference, but if a large number of LEDs are used comprehensively, the problem of color difference will become prominent. Although there are existing technologies to improve this problem, due to domestic technology and production levels, there are still differences in the same batch of LEDs in the same color area, and this difference is difficult to escape the discernment of the naked eye, and it is difficult to ensure the color of the LED display. Reductive and realistic.

LED display control chip

True color high-resolution LED electronic display as a new display medium, with its clear images and high-performance playback capabilities, is getting more and more attention. As for the LED display unit, the three primary color LED dies are its core devices, so high-quality dies with small wavelength differences and good consistency of luminous intensity should be used. This technology is mainly in the hands of world-renowned large companies, such as Japan's Nichia, etc.

Fourth, heat dissipation

Due to the great changes in outdoor ambient temperature, coupled with the display screen itself must generate a certain amount of heat, if the ambient temperature is too high coupled with poor heat dissipation, it will likely cause the integrated circuit to work abnormally, or even be burned, making the display system impossible normal work.

Therefore, we must make a comprehensive trade-off of various performances from a system perspective, grasp the order of various processing, and increase the depth of signal processing in order to make the LED full-color display display a colorful and colorful world.
