Patent ID: 7928929

Claim:
A driving method of a display device including a plurality of pixels each including m (m is an integer of m≧2) sub-pixels which are each provided with a light emitting element, comprising: setting an area ratio of the m sub-pixels to be 2 0 :2 1 :2 2 : . . . :2 m−3 :2 m−2 :2 m−1 ; providing one frame with k (k is an integer of k≧2) sub-frame groups including a plurality of sub-frames in a lighting period of each of the m sub-pixels, along with providing n (n is an integer of n≧2) sub-frames in each of the k sub-frame groups so that a ratio of lighting period lengths is 2 0 :2 m :2 2m : . . . :2 (n−3)m :2 (n−2)m :2 (n−1)m ; setting the sub-frames in the k sub-frame groups so that a same lighting pattern is repeated in each sub-frame group of the one frame, wherein the same lighting pattern being repeated in each sub-frame group comprises a same selection of sub-pixels being lit for a same amount of time in each sub-frame group of the one frame; and expressing a gray scale of the pixel by selecting a lighting state or a non-lighting state of the m sub-pixels in the sub-frames.
