Abstract
An image device with improved chrominance quality includes a plurality of RGBW pixels, a plurality of RGBY pixels, and a plurality of RBGB pixels. Each RGBW pixel includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. Each RGBY pixel includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a yellow sub-pixel. Each RBGB pixel includes a red sub-pixel, a green sub-pixel, and two blue sub-pixels. At least one row or at least one column comprises sub-pixels of having a same first color. The RGBW pixels, RGBY pixels, and RBGB pixels are mixed in the image device. The image device can solve the problem of dark yellow in the conventional RGBW display while achieving a white balance status. As a result the chrominance quality is improved.
