摘要： A display device includes a display panel, a gray scale converter, and a scale factor generator. The display panel includes a plurality of pixels. The gray scale converter is for converting gray levels of pixel data signals of a current frame by multiplying the pixel data signals of the current frame by a scale factor of the current frame. The scale factor generator is for comparing a conversion current value with an overcurrent prevention current value to generate the scale factor of the current frame.

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.
