Patent ID: 7719504

Claim:
A liquid crystal display, comprising: a first substrate comprising a common electrode; a second substrate, which comprises: at least one data line comprising a first data line; a plurality of scanning lines comprising a first scanning line and a second scanning line; and a pixel array coupled to the at least one data line and the scanning lines, wherein the pixel array comprises a first pixel and a second pixel, the first pixel is coupled to the first data line and the first scanning line, the second pixel is coupled to the first data line and the second scanning line, the first pixel has a first storage capacitor and a first pixel electrode, and the second pixel has a second storage capacitor and a second pixel electrode; a liquid crystal layer disposed between the first substrate and the second substrate, wherein the common electrode, the first pixel electrode and the liquid crystal layer form a first liquid crystal capacitor, and the common electrode, the second pixel electrode and the liquid crystal layer form a second liquid crystal capacitor; at least one first color light source and a second color light source; and a gate driver for driving the pixel array through the scanning lines within a frame period, the frame period comprises a first sub-frame period comprising a first data writing interval, and a second sub-frame period comprising a second data writing interval, wherein: in the first data writing interval, a first data voltage and a second data voltage are respectively transmitted to the first pixel and the second pixel; after the first data writing interval, the first color light source illuminates the first pixel and the second pixel; in the second data writing interval, a third data voltage and a fourth data voltage are respectively transmitted to the first pixel and the second pixel; after the second data writing interval, the second color light source illuminates the first pixel and the second pixel; and in a first pulse cycle between the first data writing interval and the second data writing interval, the first scanning line and the second scanning line are simultaneously enabled, and a predetermined voltage is simultaneously inputted to the first pixel and the second pixel so that voltages of the first liquid crystal capacitor and the second liquid crystal capacitor are simultaneously changed.
