    摘要: A touch panel device includes an excitation transducer for exciting a surface acoustic wave upon application of a burst wave and a reception transducer for receiving the surface acoustic wave and converting the same into a reception signal that are arranged at a peripheral portion of a detection area so that a position of an object touching the detection area is detected in accordance with a change in the reception signal. A control method for eliminating noises in the touch panel device includes the steps of detecting a differential between a reception signal due to a burst wave and another reception signal due to another burst wave, deciding that there is a noise if the detected differential exceeds a preset threshold value, and performing a control operation so that the detection of an object based on the reception signal is not performed in accordance with the decision.

    摘要: A burst wave is applied to an excitation element of a touch panel main body from an oscillation section so as to excite surface acoustic waves, and the excited surface acoustic waves are received by a receiving element of the touch panel main body. The received signals are A/D converted by a receiving section, and a control section calculates the contact position and the contact width of the object in contact with the touch panel main body, based on time-series changes in the received strength. Based on the received strength of surface acoustic waves, the control section controls the wave number of the burst wave to be applied to the excitation element.

    摘要: A touch panel device is provided that can detect a touched position with sufficient resolution and accuracy without requiring high accuracy in process for forming a piezoelectric thin film. In the middle portion of the glass substrate, a substantially rectangular touch area is provided. In the periphery of the touch area, plural transmission comb electrodes arranged along one of the neighboring sides of the touch area and plural reception comb electrodes arranged along the other of the neighboring sides make pairs. Surface acoustic wave signals propagate from the transmission comb electrodes to the reception comb electrodes in a slanting direction with respect to four sides of the touch area. The inside edge of the piezoelectric thin film is formed linearly along the sides of the touch area. Each of the comb electrodes 13 and 14 are arranged so that the line along the electrode finger of the transmission comb electrode and the line along the electrode finger of the reception comb electrode are non-parallel with each other in accordance with an angle of refraction of the surface acoustic wave at the boundary between the piezoelectric thin film and the touch area.
