[0002] Liquid crystal display (LCD) is a type of display used in digital clocks and many portable computers. LCD displays use two polarized materials with a liquid crystal solution between them. When an electric current passes through the liquid, the crystals are rearranged so that light cannot pass through them. Therefore, each crystal is like a shutter, which can both allow light to pass through and block light. Liquid crystal display (LCD) Currently, scientific and technological information products are developing towards the goal of being light, thin, short and small, and display products with a long history in computer peripherals are of course no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels, etc., are all subject to factors such as large size or huge 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, it can allow users to enjoy the best visual environment.
