摘要： Each of transducers of a touch panel device includes a piezoelectric thin film, a plate electrode disposed at one surface of the piezoelectric thin film and a comb-like electrode disposed at the other surface of the piezoelectric thin film. The comb-like electrode has a plurality of comb-like electrode fingers and a linear bus electrode to which one end of each of the plural comb-like electrode fingers is connected. A plurality of wiring electrodes is provided at the outer side of any of the transducers in parallel with the bus electrode of the transducer and is connected to the bus electrode and the plate electrode of any of the transducers. Each of the wiring electrodes includes an electrode base portion formed by printing silver paste containing fine particles on the substrate and an electrode main body formed by printing silver paste containing large particles and fine particles in a mixed manner on the electrode base portion.

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.

摘要： Surface acoustic waves are excited in two diagonal directions from each of IDTs (excitation elements) disposed on the upper side and the lower side of a non-piezoelectric substrate, and the surface acoustic waves propagated on a detection region are received by IDTs (receiving elements) disposed on the left side and right side of the non-piezoelectric substrate so that a position of an object touching the non-piezoelectric substrate is detected based on the reception results. In each IDT, comb-like electrode fingers are joined to two facing electrode bases (signal electrode and ground electrode) in such a manner that the comb-like electrode fingers are inclined from a facing direction of the electrode bases.

摘要： A surface acoustic waves is excited from an excitation element disposed on a substrate, the surface acoustic wave propagated on the substrate is received by a receiving element positioned on the substrate so as to face the excitation element, and the position of an object touching the substrate is detected based on the reception result. The wave number of a burst wave applied to excite the excitation element is made equal to the number of the comb-like electrode fingers of an IDT of the excitation element.
