Abstract: An overdrive accuracy adjustment device and method for use in liquid crystal display panel is presented. According to a current grayscale value of a pixel in an awaiting to be displayed image and a previous grayscale value of the corresponding pixel in an already-displayed image, the corresponding overdrive grayscale value is found from the look-up table. In order to more efficiently use the limited storage capacity of the look-up table as well as improving the accuracy of the overdrive, in accordance to the physical characteristics of the liquid crystal display panel in particular (in particular to the grayscale values which often required the overdrive), the gap size between the current grayscale values and/or the previous grayscale values with each other should be adjusted in the look-up table, without having to increase the quantity of the overdrive grayscale values stored in the look-up table.

Abstract: The present invention relates a time-sharing multiplexing driving method and framework for image signals. By means of a plurality of wiring paths, the turned-on orders of the signal switches of the pixel units in a liquid crystal panel (LCD) are sequentially controlled so that the pixel units of two adjacent phases in the panel can have the same turned-on order. This not only can avoid the situation where the switch control signal serial connecting path in the panel is so long that the control signal of the end switch will be seriously distorted for the excessively great load, but also make the variation amounts of the adjacent pixel data voltages the same. Therefore, the objective of the invention can be achieved. Namely, no joint space is generated during the image signal time-sharing multiplexing driving.

Abstract: A double-frame-rate method for reducing the time lapse of a LCD pixel between its two consecutive scans within a frame is provided. The method horizontally partitions the scan lines into (k) non-overlapping regions, each containing m1, m2, . . . , mk scan lines. The method then scans each of the regions twice before continuing to the next region and, as such, completes two passes of scanning of the entire frame. For a pixel in a region (j), the time lapse between the pixel's two consecutive scans during the frame's frame time is (mj/n) of the time lapse of conventional double-frame-rate methods.
