Abstract
A touch sensor system using vibration at touch point is provided, which includes a first sensor bar having a piezoelectric grid formed on a side surface thereof, a second sensor unit having a piezoelectric grid formed on a side surface thereof, and connected at one end to an end of the first sensor bar in a perpendicular relation, a signal processing unit connected to the first and second sensor units to receive an electric signal, and a touch point calculating unit which calculates a location of touch with respect to a screen through which the touch is inputted, based on the electric signal received at the signal processing unit.

A touch sensor system using touch point vibration, the touch sensor system comprising:
- a first sensor bar which comprises a grid made from a piezoelectric material formed on one side surface thereof;
- a second sensor bar which comprises a grid made from a piezoelectric material formed on one side surface thereof;
- a touch plate having the first and second sensor bars respectively coupled to transversal (X) and longitudinal (Y) side surfaces thereof, and wherein the touch plate is patterned with a trench pattern in a matrix form that directly corresponds to the grid of the first sensor bar and the grid of the second sensor bar;
- a signal processing unit connected to the first and second sensor bars to receive an electric signal;
- and
- a touch point calculating unit which calculates a location of touch with respect to the touch plate and the trench pattern based on the electric signal received at the signal processing unit.
