Title: Ultrasonic touch panel
Inventor: KITAJIMA HIDEKI
IPC: G06F3/043
Filed: 2001-05-14
Abstract: PROBLEM TO BE SOLVED: To lower the cost of an ultrasonic touch panel and to reduce power consumption by small-sized and simple constitution. SOLUTION: For the ultrasonic touch panel 1, ultrasonic transducers 2a-2d for which an interdigital electrode Tn on a transmission side, an ultrasonic resonator Un and the interdigital electrode Rn on a reception side are formed on the surface of a piezoelectric ceramic thin plate are provided facing one of the surfaces of a non-piezoelectric substrate 3 and the propagation paths of surface acoustic waves are arrayed so as to cross each other. In the case that a finger 4 is in contact with the non-piezoelectric substrate, the attenuation of the surface acoustic waves is detected and the indicating position of the finger 4 is calculated on the basis of the delay time of the attenuation part and the position of the interdigital electrode Tn selected in a selection circuit.  Thus, the cost of the ultrasonic touch panel is lowered and the power consumption is reduced by the reduction of the number of the selection circuits.
