Abstract
A method of increasing image gray-scale response speed comprising the following steps: to divide plural driven gate lines of an LCD into plural areas; to divide the frame interval time relative to the plural areas into plural sub-intervals, and to sequentially activate each first gate line of these areas during a time period of synchronized signals, then to sequentially activate the next gate lines of these areas, the operation is repeated; to apply an advance voltage to at least a gate line to overdrive frames, and to apply an image data voltage to at least a gate line; to repeat the above steps until the end of the entire frame interval time and to enter the next frame interval. The LCD can be fast driven by dividing of time and space. The method suits for treatment of frames of displays of various LCD's and organic light emitting diodes (OLED's).
