That is, the three insulating wires are electrically separated from each other by applying a transparent insulating film 500 between the X-axis wire 410 and the Y-axis wire 420, and between the Y-axis wire 420 and the Z-axis wire 430, respectively.

Since the signal conducting wires 400 (410, 420, and 430) cannot be made transparent, a problem occurs in that the width of the signal conducting wires 400 (410, 420, 430) is hidden so that the screen (pad) screen disposed below the user is conspicuous. Therefore, it is preferable to form the signal transmission conductors 400 (410, 420, 430) so thin that they are invisible to the user without using the magnifying glass by using the characteristic of having a very high conductivity, in the embodiment of the present invention.

- Capacitors can basically function only when the counter electrode is opposite to each other, and thus the capacitor does not have a function in the structure shown in FIG. 6.
- FIG. 7 is a conceptual view illustrating a state in which the capacitor is not operated as a capacitor in FIG. 6, even when a charge pulse is applied to the Y-axis unit cell pad 320 through the Y-axis lead wire 420 in the control board.

- FIG. 8 is a conceptual diagram illustrating a state in which a user's finger contacts the other side of the transparent base plate 100 on which unit cell pads are formed
- FIG. 9 is a conceptual diagram illustrating the equivalent circuit of FIG. 8.
- the other surface of the transparent base plate 100 serves as an electrode opposite to the unit cell pad. This is because the user's body acts as a branch line (ground) 350 due to the large charge capacity, so that "mutual capacitance" occurs between these electrodes.

For example, if two coordinates x1 and x2 are detected on the X axis and y1 and y2 coordinates on the Y axis, the combination of coordinates is (x1, y1), (x1, y2), (x2, y1), (x2). , four points of y2) occur. Of these, two points are actual touch points and two points are virtual points.
- FIG. 10 is a conceptual diagram illustrating coordinates when three touch points are shown.
- FIG. 11 is a flowchart illustrating a process of identifying an actual touch point shown in FIG. 10.
- the virtual image points related thereto are (x1, y2), (x1, Six of y3), (x2, y1), (x2, y2), (x3, y1), and (x3, y3) are formed.
- the method of identifying the actual points and the virtual points is performed through the process of FIG. 11.
- Steps S310 and S320 First, as described above with reference to FIGS. 6 to 9, X-axis, Y-axis, and Z-axis coordinates of the unit cell 300 generated according to the user's touch are detected (S310), and the detected X is detected. Creates a set of coordinates that can occur by combining axes and Y-axis coordinates. As shown in FIG. 6, in the case of three actual touch points, a total of nine coordinate bundles are generated.
- Step S330 After generating a bundle of X-axis and Y-axis coordinates that can occur through the above process, the Z-axis coordinates passing through the generated X-axis and Y-axis coordinate bundles are calculated.
- the Z-axis coordinates passing through the X- and Y-axis coordinate bundles may be calculated according to a predetermined relationship of X, Y, and Z.
- Step S340 The Z-axis coordinates measured in step S310 are searched and compared with the Z-axis coordinates calculated in step S330.
- Steps S350, S360, and S370 If there is a Z-axis coordinate in which the Z-axis coordinates calculated from the X-axis and Y-axis coordinate bundles and the measured Z-axis coordinates coincide (S350), the X-axis and Y-axis coordinate bundles are actual. It is recognized as a touch point (S360). If the Z-axis coordinates calculated from the X-axis and Y-axis coordinate bundles and the measured Z-axis coordinates do not exist, the coordinate bundles are recognized as representing virtual images (S370). In FIG. 6, the X-axis, Y-axis coordinates, and Z-axis coordinates are also shown. Actual touch points indicate that the Z-axis signal is generated, but the virtual images do not have a Z-axis signal. Thus, by reading the Z-axis signal, three actual touch points can be identified from nine combinations of X and Y coordinates.
- the user can recognize and grasp the multiple touch points.
- the identification procedure becomes more complicated, and in some cases, the multiple points Complex problems can arise such that they have the same Z axis coordinates.
- the W axis which is a separate inclination axis, may be added to the X, Y, and Z axes to enhance the identification ability in complex cases. Can be.
