    摘要: In a method of driving a display device and a driving circuit using the driving method, when a current needed to display an image corresponding to one frame is calculated based on a data signal, a second vertical start signal delayed by a first time interval more than a first vertical start signal based on the calculated current. A first gate signal is sequentially output in response to the first vertical start signal, and a display data voltage obtained from the data signal is output during a high period of the first gate signal. A second gate signal is sequentially output in response to the second vertical start signal, and a black data voltage is output during a high period of a second gate signal. Thus, the current applied to a display part is controlled, thereby reducing power consumption and improving moving image.

    摘要: In a display device, a signal controller compensates for luminance of an input image signal that corresponds to each of a plurality of pixels in accordance with a luminance compensation coefficient depending on a position of each pixel, and generates a compensation image signal. A data driver generates data signals that correspond to the plurality of pixels in accordance with the compensation image signal, and supplies the data signals to the corresponding pixels, respectively. The luminance compensation coefficient may depend on a magnitude of the input image signal.
