LCD Technology

 
LCD stands for Liquid Crystal Display. This technology has been around for a number of years but is finally able to deliver fast motion video quality displays. The thin and light form factor is attractive to consumers. While the panel (the set itself) looks thin, the technology inside is quite extensive.
 
    
1 pixel contains
3 sub pixels
     An LCD is made up of pixels (picture elements). Pixels are individual, distinct, points of light. Each pixel is made up of sub pixels consisting of red,green and blue. Together the red, green and blue sub pixes combine to form a single color picture element. A panel's resolution is determined in part by how many pixels there are. A display can have hundreds of thousands of points of light (pixels) to millions of points of light, depending on the resolution.
 
A simplified understanding of how an LCD works can be explained with four key areas that make up a panel. Light from a source at the back of the panel (A) passes through a thin film transistor (B), through the Liquid Crystal(C), and then through a color filter(D):
