Color display panel and its driving method

Abstract

Abstract PURPOSE:To attain a full-color display which has the same resolution as a monochromatic display and with the same number of picture elements by providing a translucent liquid crystal display panel and a back light source which emits the rays of light of the primary colors selectively, and selecting the light emission colors of this back light source in synchronism with the transmission and nontransmission of the translucent liquid crystal display panel. CONSTITUTION:The translucent liquid crystal display panel 1 and the back light source 3 which emits the rays of light of the primary colors selectively are provided and the light emission colors of the back light source are selected in synchronism with the transmission and nontransmission of picture elements 1a of the translucent liquid crystal display panel 1. A fluorescent display tube which is used as the back light source 3 is a plane light emitting element which emits light selectively in the primary colors, i.e. complete red, green, and blue, its response speed is sufficiently fast, and characteristics which satisfy even the display speed of a moving picture like a television screen are obtained. A light dispersing filter 2 receives the light source light from the back light source 3 and guides uniform plane light source light to the translucent type liquid crystal panel 1. Consequently, the same resolution with a monochromatic display is obtained and while thin structure is held, a color display is realized.
