The 峨 unit 41() has a plurality of first wires 412 and a plurality of second wires 414, and the first wires 412 and the second wires 414 are stacked and electrically isolated from each other. A plurality of electrical conductors 416 are respectively disposed around the corresponding first and second wires 412 and 412, and are respectively located around a plurality of mutual coupling points of the first and second wires 412 and 414. The detailed structure will be explained later. When there are two touches 込 and p2 on the touch sensitive unit 410, the Pi or 匕 and the other two mutual coupling points 01 and 造成2 cause a current or voltage change at the touch, from the capacitance value image 420 thereof. Further, the difference between the capacitance value of the touch point 匕^^, γ4) and the other two mutual coupling points g/Χ, γ6), g2 (X3, Υ4), the difference between the image wave GM and GA They are 屯, d7; touch point ρ2(χ3, γ6) 12 201015413 The capacitance value image wave captures the capacitance value image wave GlW2 of the other two mutual coupling points Gi (X" Y6), G2 (X3, γ4) The difference between G2w2 is 屯, ^, respectively, but it can be clearly seen here that the difference ^ is also much larger than the difference between the two figures, ^, 屯, and Shan. Because the conventional current or voltage change is borrowed. The single mutual capacitance variation between the first wire 412 and the second wire 414 is sensed, and in the present embodiment, the current or voltage change is made by the first wire 412 and the second wire, and the first wire is still electrically conductive. Sensing and the second wire seem to be sensed by three mutual capacitance complex changes between the electrical conductor 416 and the like, so that the mutual capacitance of the three mutual capacitances is obviously changed. It is larger than the single mutual capacitance variation, so that the true touches Ρι, P2 and the false touches Gi, G2 can be clearly distinguished. The inventor hereby emphasizes that this embodiment only has two touches, However, the two touches are on the top; the brothers who have the usual knowledge in this skill can be pushed up according to the teachings of this embodiment, so in no case will they be described. In other words, any two touches can become a virtual parallel S-shape. One of the diagonals (such as a rectangle or a diamond) is true to the vertex, such as P1, p2, ❹ Conversely, the other diagonal of the virtual parallelogram is - for a false vertex, such as G1" G2 fit conductor 4丨6 is enlarged The amount of signal difference between the adjacent tilde and the false vertices. In addition, the size of the electrical conductor 216 determines the amount of signal difference between the adjacent mutual coupling point of the real vertex and the adjacent mutual coupling point of the false vertex. For example, in the case where the thread thread does not change, the electrical conductor 416 is larger. The greater the difference in signal between the real vertices and the false vertices, the smaller the difference between the signals. Those skilled in the art will appreciate that the size of the electrical conductor 416 is adjacent to the true apex of the mutual mutual coupling point and the false apex. 13 201015413 The amount of signal difference between the mutual coupling points is not necessarily linear. In addition, based on the fact that the true vertices and the false imaginary are different from the neighboring clocks, the number of overlaps of the mutual capacitance of the occupational students will be different, and the number of overlaps of each other may be one or more. Mutual capacitance composite variation. For the sake of clarity and simplification of the illustration, in the example of the fourth figure, each vertex generates a mutual capacitance composite change amount only by one adjacent mutual overlap point, and the transfer limit is reduced (4), and in the other examples of the present invention The term is based on the distance between the adjacent mutual coupling points, and the number of adjacent mutual coupling points that generate the © mutual electric valley composite variation may be one or more. The inventor hereby prepares, because the sensing system of three mutual capacitance composite variations is easy (greater than, obvious) sensing of a single mutual capacitance variation, all embodiments of the present invention can reduce the number of guide wires. The resolution similar to the known technique 'is similar, but the amount of wire is reduced. And because of the information on the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ For example, the touch object is a finger or a soft material, and has a flexible arc surface. The greater the force of pressing down to the touch sensitive unit 410, the larger the area of the touch object contacting the touch sensitive unit 41. The larger the amount of change, the more the pressure can be used to estimate the magnitude of the pressure, the amount of change, and the change in the momentum, and the gestures associated with the pressure or pressure change can be identified, for example. By judging whether the pressure is getting bigger or smaller to judge the approach or departure of the finger, it is also possible to judge and track the movement of the finger by judging the finger-side enlargement and the other-side fade. 14 201015413 Therefore, when the above-mentioned touch-sensitive unit no contains a plurality of electrical conductors f, which should cross the mutual overlap, then the size of the electrical conductors 416 will be read as the second and fourth. With the fifth door sand limit. Shiming refers to the first figure, which is a preferred embodiment of the touch sensitive unit of the present invention. Structure 77 is not intended.

In this embodiment, the relative positions of the electrical conductors 552 can also be adjusted between the first and second wires 512, 532 or below the first and second wires 512, 532.
