摘要： PROBLEM TO BE SOLVED: To provide a highly durable capacitive coupling touch panel with high visible light transmittance that responds to a finger input as well as a touch by a non-conductive input means.
SOLUTION: There are provided coordinate detection electrodes for detecting XY position coordinates, and a transparent Z electrode. The Z electrode is arranged at a certain distance with a spacer interposed therebetween. An elastic layer is deformed along the spacer due to compression by the touch to depress the Z electrode. The distance between the Z and X electrodes and that between the Z and a Y electrodes are reduced, and capacitance is increased, thereby enabling change detection in capacitance among the X, Y, and Z electrodes (where a distance between the electrodes is changed due to depression) even by the non-conductive input means to detect the coordinates of the touch position.

摘要： PROBLEM TO BE SOLVED: To provide a technique which can determine input points in spite of a state wherein detection signals of input points overlap greatly, in a multi-touch sensor.
SOLUTION: The conventional multi-touch sensor can detect only coordinates of one input point as shown in 704 of Fig.7(g) in a state wherein detection signals of input points overlap greatly as shown in Fig.7(a). The multi-touch sensor performs peak analysis processing 705 of determining a condition for separating spatial distribution of signal intensities obtained by capacity detection 711 into a plurality of regions, on the basis of the spatial distribution signal intensities. Accordingly, the spatial distribution can be divided into two groups as shown in Fig.7(d) even in the state wherein detection signals of input points overlap greatly as shown in Fig.7(a), so that coordinates of two input points can be detected as shown in 702 and 703 of Fig.7(e).

摘要： PROBLEM TO BE SOLVED: To detect a touch position with high accuracy even if a touch area protrudes from an electrode area. SOLUTION: A shape of the touch area is assumed to be a circle, for example. In regard to an overlapped area of the touch area circle with an electrode area 6, a width in an X-direction (overlapped width X46) and a width in a Y-direction (overlapped width Y47) are obtained from sensor measurement values. When the overlapped width X46 differs from the overlapped width Y47, it is decided that the touch area protrudes from the electrode area, and calculation is made by regarding a center position of the touch area circle as a touch position.
