Abstract: The display device includes a plurality of pixels, a data driver, and a timing controller. The plurality of pixels are connected to a plurality of scan lines and a plurality of data lines. The data driver supplies a data voltage to the plurality of data lines in a light-emitting mode and supplies a neural network input voltage to the plurality of data lines in an artificial neural network mode. The timing controller is in an artificial neural network mode, and supplies a weight value control signal for performing a deep learning operation by using at least one of the plurality of pixels to the data driver. The weight value control signal is generated based on a predetermined weight value.

Abstract: A display device includes a display panel, a memory, a dithering processor, and a panel driver. The display panel includes a display surface, and the memory stores dither patterns with respect to at least one spot area included in the display surface. The dithering processor selects a dither pattern among the dither patterns in a predetermined time unit and outputs a compensation image signal corresponding to the dither pattern. The panel driver outputs a data signal corresponding to the spot area based on the compensation image signal. Each of the dither patterns includes a first grayscale area having a first grayscale value higher than a first target grayscale value of the spot area and a second grayscale area having a second grayscale value lower than the first target grayscale value.

Abstract: A display device includes a display panel including a plurality of pixels respectively connected to a plurality of data lines and a plurality of scan lines, a data driving circuit for driving the plurality of data lines, a scan driving circuit for driving the plurality of scan lines, and a driving controller for receiving a control signal and an image signal and controlling the data driving circuit and the scan driving circuit such that an image is displayed on the display panel. The driving controller identifies a first region and a second region of an image to be displayed on the display panel based on the image signal and provides the data driving circuit with an image data signal obtained by compensating for the image signal to be provided to pixels adjacent to the second region among pixels corresponding to the first region as a compensation value.
