Display device and driving method thereof

摘要

A display device has centers of three sub-pixels arranged to form a triangle together and one side of the triangle is orientated in the same direction as a vertical direction of a displayed image. When a black or white vertical line is displayed, image signal data of left and right pixels adjacent to the black or white vertical line are converted into cyan-biased or magenta-biased image signal data, thereby enhancing the visibility and readability of displayed characters.
