Guide: LED display: LED is light emitting diode, the English abbreviation of LED, referred to as LED. It is a display method by controlling a semiconductor light-emitting diode, which is roughly composed of a plurality of light-emitting diodes, usually red, which are displayed by the light being turned off. A display screen for displaying various information such as text, graphics, images, animations, videos, and video signals. Since it is used to display text, etc., there are several types of LED displays for texts, graphics, etc. Let me introduce to you what classification of LED display by display performance and what are the precautions for LED display?
What is the classification of LED display by display performance:
Video display: generally full color display
Text display: generally single color display
Graphic display: generally dual-color display
What are the precautions for LED display:
Switch note:
1. LED display switch sequence: When opening the screen: first boot, then open.
When closing the screen: first turn off the screen, then turn off the screen.
(The computer does not turn off the LED display first, which will cause the screen to appear bright, burning the lamp, the consequences are serious.)
2. When switching the LED display, the interval time is greater than 5 minutes.
3. After the computer enters the engineering control software, the LED display can be turned on.
4. Avoid opening the LED display in the full white screen state, because the system has the largest inrush current.
5. Avoid opening the LED display in the out of control state, because the system has the largest inrush current.
A computer does not enter the control software and other programs;
B The computer is not powered on;
C Control section power is not turned on.
6. When the ambient temperature is too high or the heat dissipation conditions are not good, care should be taken not to open the LED display for a long time.
7. When a part of the LED display body appears very bright, you should pay attention to turning off the LED display in time. In this state, it is not appropriate to open the LED display for a long time.
8. The power switch of the LED display often trips. Check the screen or replace the power switch.
9. Regularly check the tightness of the hook. If there is looseness, pay attention to timely adjustment, re-reinforce or update the hanger.
10. According to the environment of the display body and control part, avoid insect bites and place anti-rat medicine if necessary.
Control part considerations
1. The power cord of the computer and control part is zero and the fire cannot be reversed. It should be inserted exactly in the original position. If there are peripherals, after the connection is completed, the chassis should be tested for power.
2. When moving the computer and other control equipment, first check the connection line and the control board for looseness before power-on.
3. The position and length of the communication line and flat connection line cannot be changed at will.
4. If abnormalities such as short circuit, tripping, burning line, and smoke are found after moving, the LED display should not be tested repeatedly. It should be found in time.
