摘要： A display panel driving and scanning system includes a timing controller to divide one frame period into first to third time periods. In the first time period, an image processing device calculates an overdriving signal for a current frame based on the current frame and a previous frame. In the second time period, the image processing device outputs the current frame, and a source driver charges the capacitors of the pixels in the liquid crystal display panel based on the current frame. In the third time period, the timing controller drives a backlight driving circuit to turn on a backlight source of the liquid crystal display panel for displaying the current frame.

摘要： The present invention discloses an over-driving compensation method to shorten the response time of a passive matrix liquid crystal display, wherein N frames are arranged into a super-frame; the data of the current frame is compared with the data of the previous frame; once the data of the current frame is different from the data of the previous frame, the pictures are determined to be moving pictures; and when the pictures are determined to be moving pictures, an over-driving voltage, which is higher/lower than the traditional high-level driving voltage/the traditional low-level driving voltage, is assigned to each of from the ith frame to the jth frame of each super-frame. Thereby, the liquid crystal can faster approach or reach the specified target brightness. So the blurring of moving pictures will be greatly reduced.
