Abstract

In the modern computer industry the Laptop computer has become an exciting and revolutionary product. While some engineers work to make computers bigger, faster and more powerful, others are striving to make them possible. Due to the obvious size and power constraints it is necessary to use Liquid Crystal Devices (LCD) in Laptop Computers. These displays consist of matrices of individual LCD cells. These individual cells form the pixels of the screen. It is thus possible to display a complex pattern on the screen by controlling the state of these individual pixels. In the Apple Computer PowerBook^TM Laptop computer each pixel is 0.5 mm square and on the display there is a total of 640*480 pixels.
