FLAT PANEL DISPLAY DEVICE
First Claim
1. A flat panel display device comprising:
- a first face;
a frame having a conductive face and supporting the first face;
a cushion member interposed between the first face and the conductive face and formed of a dielectric material, wherein a thickness of the cushion member varies depending on an externally applied pressure;
a conductive film interposed between the first face and the cushion member; and
a sensor unit electrically connected to the conductive face and the conductive film respectively, which calculates and senses a variation in capacitance of a capacitor comprising the conductive face, the cushion member, and the conductive film.

Abstract
A flat panel display device that can easily determine whether it has been touched or not by sensing a variation in capacitance by using a cushion member. The flat panel display device includes a first face; a frame having a conductive face and supporting the first face and having a conductive face; a cushion member interposed between the first face and the conductive face and formed of a dielectric material, wherein a thickness of the cushion member varies depending on an externally applied pressure, a conductive film interposed between the first face and the cushion member; and a sensor unit electrically connected to the conductive face and the conductive film respectively, which calculates and senses a variation in capacitance of a capacitor comprising the conductive face, the cushion member, and the conductive film.
