Abstract

This invention provides an LCD display device without color filter thereon. A set of at least RGB LED chips, packaged inside one assembly housing, can be driven independently and provide backlight to a zone of a LCD display panel. The LCD panel includes a lower plate with TFT thereon, an upper plate with a transparent electrode thereon, and a liquid crystal layer between the lower and upper plates. Each pixel includes one TFT only, and the image can be displayed by using zone image display method. Polarizer plates can be a whole plate, zonewise or small pieces paste on the lower plate.
