Abstract:
1. The drive method for a display of grid array pixels is comprised of the following steps: writing image data provided with a grayscale code range containing multiple continuously distributed grayscale codes into pixel rows, wherein at least one row is divided into frame time and black picture time; setting up an adjusted range containing multiple grayscale codes; corresponding each grayscale code within the grayscale range to that within the adjusted grayscale range; having the grayscale codes within the adjust range to drive the display without changing a corresponded gamma voltage; overdriving the pixels to present the luminance desired by the current image; having the responsive time of the pixels shorter than the frame tine in relation to the grayscale code within the corresponding grayscale range; and writing the black picture data into the pixel row within the black picture time; inputting image data to an image comparison module of the display to judge if the image is a still or dynamic picture; setting up an adjusted range containing multiple grayscale codes; in case of a dynamic picture, mapping each grayscale code within the grayscale code range to that in the adjusted range; driving the display with the grayscale code within the adjusted range; overdriving at least one pixel row to present the luminance as desired by the current image, and writing simultaneously or synchronously within a display time data of a black picture into at least one pixel row of the display; wherein the image comparison module contains a frame memory unit to store the preceding image; an image comparator, an OD reference list process unit to process OD drive voltage, and a multiplexer to pass image data; the image comparator receives image input and compares it with the data of the preceding image stored in the frame memory unit to judge if the current image relates to a still or a dynamic picture.
