DISPLAY DEVICE AND DRIVING METHOD OF DISPLAY DEVICE

摘要

It is an object of the present invention to reduce a cause of pseudo contour when display is performed with a time gray scale method. According to the present invention, one pixel is divided into m sub-pixels so that an area ratio of each sub-pixel becomes 2⁰:2¹:2²: . . . :2^m-3:2^m-2:2^m-1 (m is an integer number of m>=2), and one frame is divided into n sub-frames so that a ratio of a lighting period in each sub-frame becomes 2⁰:2^m:2^2m: . . . :2^(n-3)m:2^(n-2)m:2^(n-1)m (n is an integer number of n>=2). Then, a gray scale is expressed by controlling a manner of lighting in each of the m sub-pixels in each of the n sub-frames.
