Display device and method for driving the same
Abstract:
There is provided a display device capable of suppressing brightness change which can occur at the time of image update in intermission driving. A display control circuit (20) includes a frame memory (101), a coercive refreshing determination section (104), a refreshing circuit (105), and an undershoot circuit (106). The coercive refreshing determination section (104) outputs an active coercive refreshing signal and an active correction instruction signal upon determining that an image is updated. The refreshing circuit (105) receives the active coercive refreshing signal, and then outputs an active output control signal. The frame memory (101) receives the active output control signal, and then outputs an image data. The undershoot circuit (106) performs, if in reception of the active correction instruction signal, a correction by making a subtracting operation to the image data received from the frame memory (101), and then outputs corrected image data.
