发明名称 APPARATUS AND METHOD FOR PROVIDING A GRAY SCALE IN LIQUID CRYSTAL FLAT PANEL DISPLAYS
摘要 A liquid crystal display is described that includes gray scale capability. Each pixel of the display is subdivided into a plurality of subpixels. Each subpixel has coupled thereto a thin film transistor, the thin film transistor coupled to the effective subpixel capacitor. The liquid crystal material is contained between the effective capacitor plates. The voltage applied to the effective capacitor resulting from current flowing through the thin film transistor controls the optical activity of the subpixel. By controlling parameters associated with the thin transistor and by controlling the voltage applied to the pixel (and the subpixel thin film transistors), the optical properties of the subpixel can be controlled as a result of the charge applied across the effective capacitor to provide an angular independent gray scale for the pixel.
