Abstract
An overdriving apparatus including a memory unit, a position unit and an overdriving unit is provided. The memory unit stores a present frame received and outputs a previous frame stored in the memory unit. The position unit generates pixel position information according to a display control signal of the present frame. The overdriving unit determines a corresponding relationship between several pixel grey values of the present frame and several display areas of a display panel according to the pixel position information, so as to select a corresponding specific table group of each of the pixel grey values from a plurality of overdriving tables. The overdriving unit further generates an overdriving frame by looking up the corresponding specific table group of each of the pixel grey values.
