Little common sense about industrial LCD screens
Common Faults in Industrial LCD Screens Industrial LCD screens have several types of faults: white screen, flower screen, black screen, screen dark, yellow, white spots, bright lines, bright bands, dark lines, dark bands, and outer film scratches.
Relatively easy to repair these faults are screen, yellow, white spots, and outer membrane scratches. The screen is actually the aging of the lamp, and it can be replaced directly. Both yellowing and white spots are backlight problems, which can be solved by replacing the corresponding backlight or light guide. The outer film scratch is the damage of the polarizer covered by the surface of the liquid crystal glass, and it can be replaced by hand. Of course, these faults that can be solved by replacement also have a lot of precautions. The lamp should be installed in place to avoid light leakage. To handle the backlight, pay attention to dust, otherwise the dust will be spotted after the screen is lit. The replacement of the polarizing film should avoid crushing the screen when the film is torn, and the dust is even more taboo. Once the dust enters during the filming, bubbles will be generated, and it is basically necessary to scrap the film again.
The protective film of the screen, this protective film is recommended to be attached when not using the industrial LCD screen, and then removed when using the industrial LCD screen, which can effectively protect the chemical coating of the outer layer of the screen, so that the outermost layer The coating will not be oxidized prematurely.
Moisture can be said to be the "natural enemy" of industrial LCD screens. In addition to avoiding drinking beverages and eating fruits on industrial LCD screens, you should also be careful not to store the machine in a humid place. Serious moisture will damage the internal components of the LCD screen . It is particularly noteworthy that in winter and summer, when entering or exiting a room with heating or air conditioning, a large temperature difference will also cause “condensation”, and the user may electrify the LCD at this time, which may cause corrosion of the liquid crystal electrode, resulting in permanent Sexual damage. For this reason we also recommend that your ambient temperature change should not be greater than 10 ° C / 10 min. Once the screen is in the water, if it is only found that the surface of the screen is foggy before starting the machine, gently wipe it off with a soft cloth and turn it on. If moisture has entered the LCD, the LCD should be placed in a warmer place, such as under a desk lamp, to gradually evaporate the water inside.
