Description
Technical Field

Background
Liquid Crystal Displays (LCDs) are one type of display for digital watches and many portable computers. LCD displays use two sheets of polarizing material with a liquid crystal solution in between. When an electric current is passed through the liquid, the crystals rearrange so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through it and blocking it. Liquid Crystal Displays (LCDs) are currently being developed towards light, thin, short, small targets, and display products with a long history around the computer are certainly no exception. Under the premise of convenient carrying and transporting, the conventional display modes such as CRT kinescope display and LED display panel are subject to the factors of overlarge volume or huge power consumption, and cannot meet the actual demands of users. The development of the liquid crystal display technology is exactly suitable for the trend of the current information products, and the user can enjoy the best visual environment no matter the advantages of right angle display, low power consumption, small volume, zero radiation and the like. However, the side of the lcd will have light leakage.
