Abstract: A display device includes a display panel, a touch sensor, a display driver and a touch controller. The display driver drives the display panel based on input image data, and generates predicted noise data corresponding to the input image data by using an artificial neural network. The touch controller receives a touch sensing signal from the touch sensor by driving the touch sensor, converts the touch sensing signal that is an analog signal into touch sensing data that are digital data, and compensates the touch sensing data based on the predicted noise data.

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.
