摘要： Surface acoustic waves are propagated in a lower-left oblique direction and a lower-right oblique direction from an excitation element located on the upper side of a non-piezoelectric substrate and then received by receiving elements located on the left side and the right side, while surface acoustic waves are propagated in an upper-left oblique direction and an upper-right oblique direction from an excitation element located on the lower side of the non-piezoelectric substrate and then received by the receiving elements located on the left side and the right side. Based on the received results at the two receiving elements, a position of an object in contact with the non-piezoelectric substrate is detected. The sensitivity in a region near the diagonal, which is influenced largely by propagation loss of the surface acoustic waves, is improved by increasing the widths of the electrode fingers of the excitation elements and/or the receiving elements, the number of pairs of the electrode fingers, or the aperture width of comb-like electrodes, according to an increase in the propagation distances of the surface acoustic waves, i.e., toward the region near the diagonal.

摘要： Each of an excitation element for exciting surface acoustic waves in two directions and a receiving element for receiving surface acoustic waves from two directions is constructed by forming a comb-like electrode on the front surface of a piezoelectric body in the form of a thin film and a plate electrode on the rear surface thereof. The comb-like electrode on the front surface has one line of bus electrode, and a plurality of electrode fingers which are extended from the bus electrode and bent in V-shape in the middle. The voltage in the excitation element and in the receiving element is controlled by providing a terminal resistance for preventing reflection of an applied AC voltage at the terminal end, between the terminal end portion of the comb-like electrode and the plate electrode, or adjusting the resistance value of the bus electrode and/or the plate electrode, or adjusting the capacitance value between the electrode finger and the plate electrode.

摘要： The position of a light blocking object is detected not only within a display screen, but also outside the display screen. With the use of the function of detecting the position in a region outside the display screen, it becomes possible to provide virtual buttons in this region and detect dust around a light retro-reflector. Dirt on the light retro-reflector is detected based on the levels of light receiving signals of optical units.
