Background

Liquid Crystal Displays (LCDs) are used in digital watches and one type of display for many portable computers. The LCD display uses two sheets of polarized material with a liquid crystal solution between them. When current is passed through the liquid, the crystals will rearrange so that light cannot pass through them. Thus, each crystal acts like a louver, both allowing light to pass through and blocking light. Liquid Crystal Display (LCD) technology information products are now developed toward the goals of being light, thin, short, and small, and it is certainly no exception to display products having a long history in the computer periphery. Under the precondition of easy carrying and transportation, the conventional display methods such as CRT video display and LED display are all limited by the factors of too large volume or huge power consumption, which cannot meet the practical requirements of users.
