Patent ID: 7352350

Claim:
A display device comprising: a pixel array comprising a plurality of pixels; a plurality of gate lines; a plurality of video signal lines; a scanning driver outputting a plurality of scanning signals to the plurality of gate signal lines; and a data driver outputting a plurality of display signals to the plurality of video signal lines; wherein the pixel array displays images in a normally black mode, wherein the scanning driver outputs to the plurality of gate signal lines in a first pixel row selection step and in a second pixel row selection step, wherein the data driver outputs the plurality of display signals in response to the selection of respective pixel rows in the first pixel row selection step which is performed every frame period and outputs display signals which display the pixel array darker than the first selection step to respective selected pixel rows in the second selection step of the pixel row, and wherein the total period of the first pixel row selection step in one frame period is longer than the total period of the second pixel row selection step in one frame period.
