Plasma display device
First Claim
1. A plasma display device comprising:
- a plasma display panel (PDP) for displaying an image;
a chassis base attached to and supporting the PDP;
an infrared ray sensor at a front surface or a rear surface of the PDP for detecting a change in amount of infrared rays emitted from the PDP; and
a controller for receiving a detection signal and determining a position of the change in amount of infrared rays, the position of the change in amount of infrared rays defining a touch position.

Abstract
A plasma display device embodying a touch panel function utilizing infrared rays that are generated when displaying an image and that are emitted in a uniform distribution manner in a display area. The plasma display device includes: a plasma display panel (PDP) for displaying an image; a chassis base attached to and supporting the PDP; an infrared ray sensor at a front surface or a rear surface of the PDP for detecting a change in amount of infrared rays emitted from the PDP; and a controller for receiving a detection signal and determining a position of the change in amount of infrared rays, the position of the change in amount of infrared rays defining a touch position.
