  • Patent number: 8242993
    Abstract: A display device includes a display panel, a timing controller, a data driver and a scan driver. The display panel includes pixels respectively electrically connected to scan lines and data lines. The timing controller calculates the statistic numbers of pixels whose gray level variations between previous and current frames cross the gray-scale level of the gray point according to scan-line-signal refresh times and high-low gray-scale lookup tables, and thus selects one of the scan-line-signal refresh times and one of the lookup tables corresponding to the lowest statistic number. The scan driver outputs scan line signals to the pixels according to the selected scan-line-signal refresh time. The data driver generates pixel data according to the selected lookup table.

  • Patent number: 7978211
    Abstract: In a liquid crystal display (LCD) device, a plurality of pixels is driven to display a first frame and a second frame in sequence. A gray-scale difference between the first frame and the second frame is detected to determine a driving mode variation between the first frame and the second frame. The number of pixels driven by a dynamic mode and a static mode in the second frame is adjusted according to the driving mode variation. Gray-scale data corresponding to the pixels in the second frame is output.
