  • Patent number: 9548031
    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.
