Abstract: A display device capable of driving at low speed is disclosed. Pixels connected to a first data line on odd-numbered display lines of a display panel are positioned on one side of the left and right sides of the first data line, and pixels connected to the first data line on even-numbered display lines of the display panel are positioned on the other side of the first data line based on a Z-inversion scheme. When a mode conversion control signal for switching to an interlaced low speed driving mode is input during a normal drive, in which a length of one frame is set to P, a timing controller expands a length of one frame for a low speed drive to (n×P), where n is a positive integer equal to or greater than 2 and assigns a length P to each of n sub-frames of the one frame.

Abstract: A display device includes an image signal processor generating modulation data of each pixel region corresponding to a display period of each frame based on an image signal and predetermined modulation value tables which are preset to different gains. The image signal processor includes a block divider and at least two data modulators. The block divider divides the display region into at least two block regions along a second direction. The at least two data modulators correspond to the at least two block regions, modulate gray scale data of each of pixel regions included in each block region based on a modulation value table, and generate modulation data of the pixel regions included in each block region. As a result, a difference in the charge amount caused by line resistance can be compensated according to the overdriving scheme, resulting in prevention of image quality deterioration.
