Abstract: A data driver includes a receiver, a transition minimization coding (“TMC”) decoder, a dithering adder and a voltage generator. The receiver receives a clock signal and first image data which is generating by removing a dithering from a dithered original image data and performing a TMC. The TMC decoder removes the TMC from the first image data to generate second image data. The dithering adder restores the removed dithering based on the clock signal and the second image data to generate third image data. The voltage generator generates a plurality of data voltages based on the third image data.

Abstract: A display panel driving apparatus includes a data driving part, a data driving part and an off voltage controlling part. The data driving part is configured to output a data signal to a data line of a display panel. The gate driving part is configured to output a gate signal to a gate line of the display panel. The off voltage controlling part is configured to receive a first off voltage and a second off voltage applied to the gate driving part to generate the gate signal, measure a leakage current of the gate driving part, and control the first off voltage based on the leakage current. Thus, display quality of a display apparatus including the gate driving part may be improved.
