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.
