LCD stands for Liquid Crystal Device and is a flat display device, which utilizes a small amount of the electric power.  LCD uses two techniques for producing the colors active matrix and passive matrix.  The LCD screens are used in the laptops, CD players, digital clocks, microwave ovens and watches. The application of the liquid crystal display technology is very wide. The LCD screens used in the laptops are backlit or transmissive.  If you want to purchase a LCD, the important features to consider before buying are resolution, matrix type, refresh rate, brightness, viewing angle, dot pitch, contrast ratio and aspect ratio.

In color LCD screens, each pixel is divided into the three colored cells such as red, green and blue. Each cell is controlled individually to produce the millions of the colors for that cell.  High resolution color display computer monitors use the active matrix structure.   

The active matrix technologies include the twisted nematic, in-plane switching and vertical alignment.   The top vendors of the LCD screens are Sony, Samsung, Toshiba, Sharp, Panasonic, LG, Sanyo, Acer, HP, Fujitsu, ViewSonic, Xerox and Vizio.
