Abstract: A display driving circuit for driving a display panel includes a control logic that adjusts brightness of a first partial area by adjusting pixel data values included in partial image data to be displayed on the first partial area of the display panel based on received brightness control information, and a data driver that generates image signals by digital-analog conversion of pixel data values provided from the control logic, the data driver providing the image signals to the display panel.

Abstract: An electronic device includes a display panel that includes a first region including first pixel groups and a second region including second pixel groups, and a compensation circuit. The compensation circuit may receive first image data. The compensation circuit may compensate to generate second image data in response to a determination that the first image data corresponds to at least one of one or more particular first pixel groups that are adjacent to a boundary between the first region and the second region or one or more particular second pixel groups that are adjacent to the boundary. The compensation circuit outputs the second image data to the display panel.

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.
