Abstract

A color LCD panel in which a plurality of OLED are formed on the upper surface of the lower panel of the color LCD panel to be the back light source of the color LCD panel is disclosed in the invention. Each individual OLED corresponds to a pixel of the LCD panel in order to be the independent self-emitting light source of the pixel. Each OLED is always on and ready to emit one of the three primary colors, red, green, or blue. Thus, every pixel of the color LCD panel has its independent self-emitting light source. Therefore, the back light module and color filter in conventional color LCD panels are not needed.
