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 timing controller resetting circuit including: a resistor connected to an output node from which a reset signal is output and a first voltage source which supplies a first voltage; a capacitor connected to the output node and a second voltage source which supplies a second voltage that is lower than the first voltage; a reference voltage source configured to generate a reference voltage that is lower than the first voltage and higher than the second voltage; a comparator including a first input terminal which receives the first voltage, a second input terminal which receives the reference voltage, and an output terminal which outputs a comparison result signal generated by comparing the first voltage with the reference voltage; and a transistor including a first terminal which is connected to the output node, a second terminal which receives the second voltage, and a gate terminal which receives the comparison result signal.

Abstract: A method of driving a display apparatus includes determining a duration of a blank interval between a first frame and a second frame, wherein the second frame is subsequent to the first frame, and modulating a common voltage during the blank interval when the duration is longer than a first reference time, wherein an average of the common voltage is fixed during the blank interval.
