Abstract: A display panel driving apparatus includes a data processor configured to receive N-th line data of image data. N is a natural number not less than 2. The data processor is further configured to perform a first line delay on the N-th line data to output (N−1)-th line data, to output (N−1)-th line substitution data which is obtained by N-th line substitution data, which is based on the N-th line data and the (N−1)-th line data, and to compensate the N-th line data based on the N-th line data and the (N−1)-th line substitution data to output compensation image data. The display panel driving apparatus further includes a data driver and a gate driver.

Abstract: A display device includes a display panel and a display panel driver. The display panel driver includes an over-driver which selects an over-driving data from an over-driving pattern which moves to a predetermined direction, generates a reference line based on a first polynomial expression generated based on the over-driving data, and generates an over-driving data lookup table by moving the reference line, a data driver which outputs a data signal generated based on the over-driving data lookup table to the data line of the display panel, and a gate driver which outputs a gate signal to the gate line of the display panel.
