1.LED display screens belong to semiconductor devices, so they require the best working mechanism when the ambient temperature is around 25 ℃. However, in reality, it is difficult for us to achieve this. In the summer, the temperature is 40 ℃, and in the winter, it is -30 ℃. At this point, the efficiency and performance of LED display screens will be inconsistent, because the brightness attenuation and decrease of the red, green, and blue lights are different under different temperature conditions. At 25 ℃, their white balance is normal.
2 switch sequence. When turning on the display screen, first turn on the computer and then turn on the screen. When turning off the display screen: turn off the screen first, then turn off the computer (turning off the computer first without turning off the display screen can cause high bright spots on the screen, burn out the light tubes, and have serious consequences.) The time interval between turning on and off the screen should be more than 5 minutes. After the computer enters the engineering control software, the screen can be opened and powered on. Avoid turning on the screen in full white mode, as the system's surge current is at its maximum. Avoid turning on the screen in a state of loss of control, as the system's surge current is at its maximum. When the ambient temperature is too high or the heat dissipation conditions are poor, attention should be paid not to turn on the screen for a long time. When a very bright line appears on a part of the electronic display screen, attention should be paid to turning off the screen in a timely manner, and it is not advisable to turn on the screen for a long time in this state. The power switch of the display screen often trips, and the LED unit board screen should be checked or the power switch should be replaced in a timely manner. Regularly check the firmness of the connectors. If there is any looseness, please adjust it in a timely manner, reinforce or update the suspension components. According to the environment of the large screen display screen and control part, avoid insect bites and place rodent repellent if necessary.
The power supply is also very important. Due to its different working stability, output voltage value, and load capacity under different temperature conditions, the power supply plays a logistical role, so its support ability directly affects the quality of the screen.
Regularly check for viruses and delete irrelevant data. Master the setting of control parameters, modification of basic data presets, proficient in installation methods, original data recovery, and backup. Proficient in using programs, operations, and editing. Software backup: WIN2003, WINXP, applications, software installation programs, databases, etc. It is recommended to use "one click restore" software for easy operation. Non dedicated personnel, please do not operate software systems.
