Abstract: A display device may include a display panel, N receiving antennas integrated with the display panel, where N is an integer greater than 2, a communication module, and a display driver. The communication module receives a video communication signal using a subset of receiving antennas of the N receiving antennas and an audio communication signal using at least one receiving antenna of the N receiving antennas that is different from the subset of receiving antennas and generates original video data based on the video communication signal and audio data based on the audio communication signal. The display driver receives the original video data from the communication module and drives the display panel based on the original video data.
