Abstract:
1. A display device comprising: a controller configured to output a row rewriting control signal indicating whether there is a difference between successive two frames in at least one of a first pixel to an n-th pixel (n is a natural number of two or more) arranged in the same row, and a column rewriting control signal indicating whether there is a difference between the successive two frames in a k-th pixel (k is a natural number more than or equal to one and less than or equal to n); a first scan line electrically connected to the first pixel to the n-th pixel, the first scan line being operationally connected to the controller; a second scan line electrically connected to pixels arranged in the same column as the k-th pixel, the second scan line being operationally connected to the controller; a signal line electrically connected to the pixels arranged in the same column as the k-th pixel, the signal line being operationally connected to the controller, a first shift register for driving the first scan line, which is configured to sequentially output selection signals from output terminals in a first sampling period for driving the first scan line; a first latch for driving the first scan line, which is configured to retain the row rewriting control signal supplied when a selection signal is input, and output the row rewriting control signal in a vertical retrace period following the first sampling period for driving the first scan line; a second latch for driving the first scan line, which is configured to retain the row rewriting control signal input from the first latch for driving the first scan line, and output the row rewriting control signal in the vertical retrace period and a second sampling period for driving the first scan line following the vertical retrace period; and a first buffer configured to select, in accordance with the row rewriting control signal input from the second latch for driving the first scan line, whether a selection signal is supplied to the first scan line in a horizontal scan period included in the second sampling period for driving the first scan line, wherein the k-th pixel comprises:
