LCD MONITOR
Liquid Crystal Display (LCD) stands for Liquid Crystal Display. Liquid crystals are transparent substances exhibiting both sold and liquid matter properties. Light passing through liquid crystal follows the alignment of the molecules that make them up. Applying electricity changes their molecular alignment thus changing the way light passes through them, and by putting these individual displays together you can create a display screen which is tremendously smaller then our CRT (Cathode Ray Tube) monitors. There are two main principles applied in making LCD. The first principle consists of sandwiching liquid crystals between two finally grooved surfaces where the groves on one surface are perpendicular to the groves on the other. Since molecules on one surface are aligned north to south and the molecules on the other surface are aligned east to west. Then the molecules in between are forced into a twisted state of 90 degrees. Applying a voltage to the liquid crystal rearranges the molecules vertically allowing light to pass through. The second principle of the
