Display apparatus for extracting background and image data and method of driving the same

A display apparatus comprising:

• a first image sensor configured to generate first background image data by capturing a first background image of a rear side of the display apparatus;
• a first display panel comprising a plurality of first pixels arranged in a first matrix, the plurality of first pixels including a first group of pixels disposed on a first area of the first display panel and a second group of pixels disposed on a second area of the first display panel;
• a first timing controller configured to extract first partial image data corresponding to the first area from input image data received from an external device, and to extract first partial background image data corresponding to the second area from the first background image data;
• and
• a data driver configured to generate first data voltages based on the first partial image data, to generate second data voltages based on the first 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 such that the first display panel displays a composite image of the first partial image data and the first partial background image data.
