Patent ID: 8599176

Claim:
An image display device comprising: a display unit including pixels arranged in a matrix, a vertical driver that outputs a gate signal to the display unit, a horizontal driver that outputs multi-bit image data to signal lines of the display unit, wherein each pixel is comprised of: a memory part that holds the multi-bit image data; a plurality of sub-pixels fewer than a total number of bits for defining the multi-bit image data, and wherein area sizes of at least two of the plurality of sub-pixels are different and the pixel represents a grayscale corresponding to the input image data held in the memory part by time-division driving of said plurality of sub-pixels in accordance with each logic value corresponding to one of the bits of the input image held in the memory part, and further wherein each sub-pixel includes a memory element and drive circuit and a duration of a selection signal supplied to each drive circuit of a sub-pixel corresponds to the respective bits of the input image data of the sub-pixel.
