Four-color transflective color liquid crystal display
The pixel in a transflective color LCD panel of the present invention has an additional sub-pixel area. The pixel is divided into three or more color sub-pixels in R, G, B and at least one sub-pixel M. Each of the color sub-pixels is divided into a transmission area and a reflection area to display color image data. The sub-pixel M can be entirely reflective or partially reflective for displaying a further image data. Two or more algorithms are used to compute the further image data based on the color image data. A selector is used to select one of the algorithms for displaying the further image data. The algorithm selection can be used by a user or automatically selected according to the brightness of ambient light. The transflective LCD panel can be used in a reflective mode when the ambient light reaches a brightness level.
