Abstract
An apparatus for driving a display panel includes a first memory which stores a frame image data, a second memory which stores overshooting information. The apparatus receives an image signal from an external system via a CPU interface process. The second memory stores a difference data between the frame image data and an overshooting data. The overshoot is then calculated from the difference data and the frame image data. The apparatus also includes a two-line memory which stores an image signal of an n-th frame in a line unit and an image signal of an n−1-th frame in another line. The two-line memory compares the consecutive two frame data, so that the apparatus extracts overshooting information from a look up table.
