Abstract: An n-th stage (wherein, n is an integer) of the stages of a gate driving circuit includes a pull-up part, a first variable mode part and a second variable mode part. At least one of the first and second variable mode parts includes a variable element. The variable element comprises a first thin-film transistor (TFT) turned on in response to a first level voltage of the first or second direction signal, a second TFT applying the first or second direction signal to a control part of the pull-up part in response to an output signal of a previous stage or an output signal of a next stage, and a third TFT connected to the second TFT through the first TFT.

Abstract: A method of driving a flat-panel display device divides a frame into areas and makes the boundary of each area inconspicuous, to properly show images on the display. The method prepares compensation data whose voltages are substantially equal to those of video data provided at the start of a horizontal scan period and supplies the compensation data to video bus lines in a blanking period of the preceding horizontal scan period.
