What Is an LED Display?

LED display (LED display) is a flat-panel display, consisting of small LED module panels, used to display text, images, video and other information equipment. ^[1]

The LED display is an electronic display composed of LED dot matrix. The display content such as text, animation, pictures, and video are changed in time by changing the traffic light beads on and off, and the component display is controlled through a modular structure. It is mainly divided into display module, control system and power system. The display module is a dot matrix of LED lights that constitutes the screen to emit light; the control system is to regulate the light on and off in the area to convert the content displayed on the screen; the power system is to convert the input voltage and current to meet the needs of the display screen. ^[3]

LED display is a new type of information display media, which uses light emitting diode dot matrix

There are various types of LED display screens, which are roughly classified according to the following methods:

(1) Press

(1) High

(1) Equipped with a full-color display, the introduction of higher-quality imported LED cores, making the screen image high-definition, uniform color, less power consumption, light screen body, thin screen layer, wide area

1. Switch sequence:

When opening the screen: power on first, then open the screen. ^[1]

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 display body to have bright spots, and the led will burn the lamp, with serious consequences.)

2. The interval between switching the screen should be more 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. ^[1]

6. 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.

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

8. Regularly check the firmness of the joint. If there is looseness, pay attention to timely adjustment, re-reinforce or update the hanging pieces. ^[1]

9. When the ambient temperature is too high or the heat dissipation conditions are not good, LED lighting should be careful not to open the screen for a long time. ^[1]
