True color LCD industrial screen in the normal use process, easy to encounter a variety of failure problems, especially the display installation is relatively low. Let's talk about how to deal with water in true color LCD industrial screen today.
1. Absorb a lot of water with a cloth or towel as soon as possible, and then dry it. Pay attention to power-off operation.
2. After drying the screen, continue to energize and aging. Specific operation steps are as follows.
Phased operation:
All-white brightness of 10%, power on aging time of 8-12 hours.
All-white brightness of 30%, time for 12 hours
All-white brightness of 60%, time for 12-24 hours
All-white brightness of 80%, time for 12-24 hours
All-white brightness is 100%, time for 8-12 hours
3. There is basically no problem after completing the above steps, but the following points should be noted in the operation process.
① When water enters the filter, corresponding measures should be taken in time without delay.
② Quickly dry the water inlet screen.
③ Do not put the flood screen into the air box, otherwise the LED bulb may be damaged.
④ Pay attention to whether there is water in the air box.
⑤ If the screen body after water inlet is not treated in time, it may affect the stability of the screen body, and the dead light may be found when power on aging.
⑥ Inflow into the true color LCD industrial screen if the body in the air box for more than 72 hours, there is basically no repair value. Please handle with care.
The above is the emergency treatment plan corresponding to the display into the water problem. Applicable to any LCD display.
Colleague true color LCD industrial screen starter polarizer is an important part of the optical system. The polarizer scratch will affect the display, and the internal colloid will show local yellow spot after aging.
How should LCD replace the polarizer?
The fastest way to remove the polarizer after the separation of the glass cover of a true color LCD industrial screen is to use a debonding agent to remove the polarizer directly. After pressing directly for 2 seconds, let the blade penetrate the LCD and then push slowly. However, another method is to use a form of soldering iron. One is to jam the blade in the soldering iron into the polarized light, press the LCD with one hand, lift the polarized light with two fingers, slowly cut the soldering iron blade left and right, and slowly shovel up the polarized light.
True color LCD industrial screen polarizer is very thin. If there are scratches, punctures and abrasions, they cannot be used in production, so use them with care.
