LCD liquid crystal display is a liquid crystal display device used in most electrical appliances. LCD liquid crystal display has many years of history and experience in the display industry. It can be well combined with various electrical appliances. At the same time, LCD liquid crystal display The screen also has a lot of LCD display screens, also called LCD screens. The English name is LCD Crystal Display, which is a kind of flat panel display. Screen display for TVs and computers. The advantages of the lcd display are low power consumption, small size, and low radiation. The lcd liquid crystal display uses two electrodes to contain a three-layer structure of liquid crystal molecular solution, so that when the current passes through the liquid, the molecules are rearranged for imaging purposes. The lcd display uses two sheets of polarized material with a liquid solution between them. When the current passes through the liquid, the molecules are rearranged so that light cannot pass through them. Therefore, liquid crystal molecules allow both light to pass through and block light. At present, liquid crystal display (LCD) products are moving toward light, thin, short and small targets.
What is the LCD display
Traditional display methods, such as CRT image tube displays and LED display boards, are subject to factors such as high volume and power consumption, and cannot meet actual needs. The development of liquid crystal display technology is in line with the current trend of information products. LCD LCD display has the advantages of right angle display, low power consumption, small size, zero radiation, etc., so that users have the best visual environment.
At present, liquid crystal display technology is mainly divided into three technologies: TN, STN, and TFT. The TN type liquid crystal display technology is the most basic technology of liquid crystal display, and then other types of liquid crystal display can be said to be improved by using the TN type as the origin. The TFT type liquid crystal display is relatively complicated, and the main components include a fluorescent tube, a light guide plate, a polarizing plate, a filter plate, a glass liquid crystal display glass substrate, an alignment film, a liquid crystal material, a thin mode transistor, and the like.
Lcd LCD display advantages
One, thin, does not occupy the place.
Second, no radiation, good for health.
Third, no flicker, good for the eyes.
Fourth, low energy consumption and energy conservation.
Five, completely flat, no visual distortion.
Lcd LCD display shortcomings
First, there is a viewing angle limit.
Second, there is a response speed, which will produce a picture smear.
Third, the degree of color reproduction and realism can also be improved.
Fourth, the brightness is limited.
