  • Patent number: 8922596
    Abstract: A liquid crystal display (LCD) overdriving method, an LCD overdriving device and an LCD are disclosed. The LCD overdriving method improves displaying quality and a response speed of the LCD comprising the following steps of: receiving by a scaling controller, a previous frame image grayscale value stored into a frame buffer of the scaling controller; receiving a next frame image grayscale value by the scaling controller and sending the previous frame image grayscale value and the next frame image grayscale value to a time schedule controller so that the time schedule controller looks up a lookup table and outputs an overdriving grayscale value. The present disclosure can effectively save the cost by eliminating the need of providing an additional frame buffer in the time schedule controller. Furthermore, as image grayscale values of only two pixels need to be stored in the time schedule controller, it can save more memory spaces.
