Abstract: An electroluminescent display device includes a display panel including pixels, a storage circuit, a luminance compensation circuit and a data driver. The storage circuit stores information on a leakage curve indicating a luminance change value of a target pixel according to a change of an input pixel value of a neighboring pixel, the plurality of pixels including the target pixel and the neighboring pixel. The luminance compensation circuit receives input pixel values corresponding to the pixels and generates compensated pixel values respectively corresponding to the pixels by compensating for lateral leakage based on the leakage curve, where the lateral leakage is caused by leakage currents through a common conduction layer of the pixels. The data driver drives the pixels based on the compensated pixel values. The exact (or close) luminance of the input image is realized by compensating for the luminance distortion.

Abstract: A display device is provided. The display device may include pixels arranged in rows and columns, gate drivers connected to the rows of the pixels through gate lines, source drivers connected to the columns of the pixels through source lines, and a timing controller configured to control the gate drivers and the source drivers. The source driver associated with the specific pixel among the source drives may first supply an overdrive voltage corresponding to a final overdrive value to a source line connected to the specific pixel and then supply a source line voltage corresponding to a current value of the specific pixel to the source line. The overdrive controller may change weight values of at least two overdrive values based on a position of the specific pixel and interpolate the at least two overdrive values.
