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.

Electronic devices and operating methods of electronic devices

A display device includes a display panel including an under display camera (UDC) region and a non-UDC region, the UDC region including a plurality of sub-regions, and processing circuitry configured to, receive image data, select at least one first filter from a plurality of filters based on a spatial coordinate value of the received image data, the plurality of filters corresponding to a respective sub-region of the plurality of sub-regions, and perform first pixel rendering for the UDC region based on the at least one first filter and the image data, and the at least one first filter is generated based on a pixel arrangement pattern of the UDC region.

Display device and operating method of display device

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.

Display device predicting noise for touch sensor and computing system

A display driving circuit for driving a display panel, including a first memory configured to store main image data received from outside of the display driving circuit; a second memory configured to store first additional image data in a normal mode, and to store second additional image data in an Always On Display (AOD) mode having lower power consumption than the normal mode; a normal mode controller configured to operate in the normal mode according to the first additional image data stored in the second memory; and an AOD mode controller configured to operate in the AOD mode according to the main image data stored in the first memory and the second additional image data stored in the second memory.

Display driving circuit

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.

Display driving circuit, display device including the same, and method of operating the display driving circuit

A display driving device includes an encoding unit and a frame memory. The encoding unit is configured to generate final mode information and a compressed bit stream based on a macro block and a first reference pixel, and generate a final bit stream using the final mode information and the compressed bit stream. The frame memory is configured to store and provide the stored final bit stream to a decoding unit. The final mode information includes mode information and a reconstruction reference value. The mode information indicates a selected mode from a plurality of modes, each of the plurality of modes indicating selection pixels and non-selection pixels in the macro block. The selection pixels are pixels in the macro block selected for undergoing a compression operation, the non-selection pixels are pixels not selected for undergoing the compression operation, and the reconstruction reference value indicates encoding information for the non-selection pixels.
