Patent ID: 7768604

Claim:
A method for improving viewing quality of a transflective liquid crystal display having a first side, an opposing second side, and a liquid crystal layer disposed between the first and second sides, the display comprising a plurality of pixels, at least some of the pixels comprising a plurality of color sub-pixels, each color sub-pixels adapted for displaying a single color, each sub-pixel comprising a transmissive electrode and a first reflective electrode, the transmissive electrode disposed adjacent to the second side for allowing light entering the sub-pixel from the second side to be transmitted through the transmissive electrode and the liquid crystal layer and then through the first side, the first reflective electrode disposed adjacent to the second side spaced from the transmissive electrode for allowing a part of light entering the sub-pixel from the first side through the liquid crystal layer to be reflected by the first reflective electrode through the liquid crystal layer back to the first side, and wherein the liquid crystal display is operable in a first voltage mode and in a second voltage mode for controlling optical behavior of the liquid crystal layer, said method comprising the steps of: electrically connecting at least one second reflective electrode to the transmissive electrode, the second reflective electrode disposed adjacent to the second side spaced from the first reflective electrode, allowing a further part of the light entering the sub-pixel from the first side through the liquid crystal layer to be reflected by the second reflective electrode through the liquid crystal layer back to the first side; operating the first reflective electrode at the first voltage mode; and operating the transmissive electrode and said at least one second reflective electrode at the second voltage mode.
