LCD LCD Screen Connection Performance And Reliability

1.Life span

Liquid crystal display devices, whether in theory or in practice, have a long life, tens of thousands of hours of no problem, the common portable computer monitor if not man-made damage, generally is the backlight aging, brightness decline. Replace a backlight tube to rejuvenate. Compared with other displays, whether PDP, OLED, FED, VFD life is not as good as liquid crystal display. The material purification of OLED is difficult to solve, which affects its life, and the life of PDP is restricted by the aging of phosphor and the change of air pressure in the tube.

The only thing that can match the life of a liquid crystal display is an inorganic LED. But it is difficult to make a flat panel display device.

2.Connection performance

The difficulty of connecting the external leads of flat panel display devices lies in the high density, and some are still non-metallic materials, such as ITO. Liquid crystal display is such, so with the development of liquid crystal display has developed a series of connection technology, such as COB, COF, COG and so on. Can meet the requirements of use.

Other types of flat panel display connection, generally use the liquid crystal connection technology, according to their own characteristics to be transformed, such as PDP connection, must consider voltage resistance, anti-breakdown; OLED must ensure that the connection resistance is as small as possible. In short, the external connection of the liquid crystal display device working by low voltage is relatively easy to solve, and the external connection of the luminous display device with high voltage and large current is relatively difficult

3.Reliability

The reliability of the liquid crystal is the highest, as long as it does not fall, damage, ten years free maintenance can be. While PDP is a high-voltage device, OLED is a current-type device, and their reliability is not as good as liquid crystal display.
