LCD screens are a type of display used in digital timepieces and many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When the current passes through the liquid, the crystals are rearranged so that light cannot pass through them. Therefore, each crystal is like a blind, allowing both light to pass through and block light. Liquid crystal displays (LCD screens) At present, scientific and technological information products are developing toward light, thin, short, and small targets. Display products with a long history in the periphery of computers are no exception. Under the premise of portability and portability, traditional display methods such as CRT image tube displays and LED display boards are subject to excessive volume or power consumption, and cannot meet the actual needs of users. The development of liquid crystal display technology is in line with the current trend of information products. Whether it is right angle display, low power consumption, small size, or zero radiation, users can enjoy the best visual environment.
