KEY IR PCB

Light leakage:

In the black screen and dark environment of the integrated display screen of the touch screen, the display area of ??the display area has obvious paleness, color cast, and light transmission through the gap.

 

cause:

If the touch screen displays, the leakage of light from one machine mainly occurs on the panel. This is because some panels have problems or poor quality during transportation and cause more serious leakage. In addition, it may be because the liquid crystal on the screen is not closely related to the picture, which causes the light bulb to directly emit light.

 

Solution:

When purchasing a touch screen, the monitor should check the quality from five colors: red, green, blue, white, and black. This will not only help you understand some basic parameters of the product, but also effectively avoid unnecessary troubles such as dead pixels, bright spots, dark spots, light leakage, etc. in the purchase of the product.
