2, the liquid crystal display (LCD) display for a type of digital type watches and many portable computers. LCD displays use two sheets of polarizing material with a liquid crystal between Character LCD Module them is added. When current flows through the liquid causes the crystals to rearrange , so light can not through them . Therefore, each crystal like blinds , both allow light to pass through and can block the light. Liquid crystal display (LCD) technology information products are currently moving light, thin, short, small development goals , with a long history in the computer peripheral products in the display is certainly no exception. Under easy to carry and transport for the former title , such as traditional CRT display CRT monitors and LED display boards, etc. , are subject to too large or very huge power consumption and other factors , could not reach the actual needs of the user. And the development of LCD technology just to meet the current trend of information products , whether it is at right angles to the display , low power consumption , small size, excellent radiation or zero
