    摘要： A display apparatus time-divisionally expresses gradation values allocated to the sub-frames so that the gradation value of the single frame is expressed by a total of the gradation values of the sub-frames. Each of the plurality of sub-frames includes a plurality of weighted elements with different gradation values to express the gradation values by powers of two. A lighting controller performs control such that the weighted elements in at least one of the plurality of sub-frames in one frame are aligned in an order different from an order of the weighted elements in at least one of the plurality of sub-frames in another frame and, of the plurality of weighted elements in at least one of the plurality of sub-frames in the single frame, the weighted element at the end of the timeline turns OFF a corresponding one of the light emitting elements.

    摘要： A retention unit which retains input data, and a light emission control unit which compensates a value of a drive current that flows to a light emission element based on the input data which is retained in the retention unit, are provided in each pixel unit of a display device. While the light emission control unit displays input data of an image of an Nth frame during a light emission period TL (N) by driving the light emission element, input data of an image of an (N+1)th frame is written to the retention unit which becomes a pair together with the light emission control unit, as processing in a write processing period TS (N+1) of the (N+1)th frame.
