CD display is widely used in display products at present, such as large size LCD TV, LCD splicing screen, small size smart phone, tablet computer, etc. Previously, the old display technology such as plasma also had a certain market share, but with the development of LCD technology, other display products have gradually disappeared.

The English name of LCD is LiquidCrystalDisplay, which is a technology based on white light penetrating through multi-color filter equipment to produce different colors. After penetrating, white light will form basic colors such as red, yellow and blue, and can control the light transmittance of each pixel, so that different colors can be displayed.
However, LCD displays also have unavoidable defects. Because all images are generated by white light, it is very difficult to display black scenes. Because there are some light leaks, black is not otherwise dark when displaying night scenes.
LCD display screen is composed of many small pixels on the screen display. At present, its mainstream resolution has reached more than 200 pixels, and even 4K display technology has appeared in the market.
All LCD displays need some form of white backlight, such as CCFL backlight, LED backlight, etc. With the continuous progress of display technology, the purpose of backlight is to improve the brightness of the screen, distribute it more evenly, and the thickness of the overall product tends to be lighter and thinner.
With the advancement of various display technologies, each major has its own research direction, such as LG's IPS hard screen technology, Samsung's PLS hard screen technology, etc., which has improved the original LCD technology to a certain extent. For example, the viewing angle is more extensive, and 178 degrees of viewing range can be achieved both front and side, especially in the field of industrial LCD splicing screen, IPS technology has basically replaced LCD panel, and it is believed that this will also become the future development trend of large size LCD display.
