  • Patent number: 8558816
    Abstract: A plasma display device that enables a reduction of costs in implementing a touch panel function using infrared rays generated when displaying an image, which are emitted in a substantially uniform dispersion from a display area. One embodiment includes a plasma display panel (PDP) for displaying the image and a pair of infrared sensor cameras at two corners of the PDP. The infrared sensor cameras are either on the front or rear side of the PDP, and are utilized to detect changes in the amount of infrared rays emitted from the PDP. A controller determines a position where the amount of infrared rays is changed, which corresponds to a touch position, and transmits a detection signal indicating the location of the change in the amount of infrared rays. The infrared sensor camera has a lens with a view angle in the range of 90° to 180°.
