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.

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： The present invention relates to a gamma data generation method of a display device. In the method, gamma data including red gamma data, green gamma data, and blue gamma data is determined. A target luminance and a target color coordinate of a first reference gray are determined. Then, an image is displayed on a display device based on red, green, and blue input image signals for a first reference gray, and a first luminance and a first color coordinate from the image are measured. Then, it is determined whether a coordinate difference between the first color coordinate and the target color coordinate and a luminance difference between the first luminance and the target luminance are in an allowable error range or not. The first luminance and the first color coordinate are converted to a first coordinate of a CIE XYZ coordinate system, and the target luminance and the target color coordinate are converted to a target coordinate of the CIE XYZ coordinate system if the coordinate difference and the luminance difference are not in the allowable error range. Finally, the red gamma data, the green gamma data, or the blue gamma data is corrected so that a red luminance, a green luminance, or a blue luminance of the image is changed according to a comparison of the first coordinate of the CIE XYZ coordinate system with the target coordinate of the CIE XYZ coordinate system.
