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

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.
