Abstract
A touch panel including an upper substrate on which upper electrodes are formed; a lower substrate on which lower electrodes are formed to intersect the upper electrodes cross, the lower substrate being disposed to face the upper substrate; and a piezoelectric element disposed between the upper substrate and the lower substrate to detect an input position. Accordingly, an input position on the touch panel can be detected without a power supply unit.
Claims13
A touch panel to detect an input position corresponding to a certain location where application of force is applied, comprising:
- an upper substrate on which upper electrodes are formed;
- a lower substrate on which lower electrodes are formed to intersect said upper electrodes in a cross pattern, said lower substrate being disposed to face said upper substrate;
- and
- a piezoelectric element disposed between said upper substrate and said lower substrate to detect an input position corresponding to a certain location where force is applied.
A touch panel to detect an input position corresponding to a certain location where application of force is applied, comprising:
- an upper substrate;
- a lower substrate, said lower substrate being disposed to face said upper substrate;
- and
- a polarization element disposed between said upper substrate and said lower substrate to detect said input position based upon the application of force to a region of the upper substrate.
