  • Patent number: 10095456
    Abstract: A display apparatus includes an image sensor, a display panel, a timing controller, and a data driver. The image sensor senses a background image and generates background image data based on the background image. The display panel includes a first group of pixels disposed on a first area of the display panel and a second group of pixels disposed on a second area of the display panel. The timing controller extracts partial image data corresponding to the first area from input image data and partial background image data corresponding to the second area from the first background image data. The data driver generates first data voltages based on the partial image data, generates second data voltages based on the partial background image data, to output the first data voltages to the first group of pixels, and to output the second data voltages to the second group of pixels.
