by davoomac on April 16th, 2006 LCD (Liquid Crystal Display) LCD projection technology is the current leader of the pack, having captured the majority of the market share of all projectors sold. Most LCD projectors have three panels. Each panel is a prism that allows blue, red, or green light through its pixels. These separate colors are then converged and projected. Electrical signals turn on pixels within a set based on the resolution of the unit. LCDs are known to produce greater color definition, offering more shades or variations of color than single-chip DLP projectors. DLP projectors can sometimes burn definition out of the highlights and shadows with their vibrant colors. Newer LCD projectors include special optics enhancers like micro-lens array that minimize pixelization known as the “screen door effect.” New LCD projectors have contrast ratios as high as 800:1. By comparison, DLP projectors contrast ratios are as high as 3000:1. The portability and brightness of LCD projecto
