Description of the invention: [Technical field of the invention] The present invention relates to the field of touch panels, the single-contact position of the board is virtual multi-touch ... about the function of a resistive touch surface Sensing method. [Prior Art] The input system of the electronic device is based on a keyboard and an intuitive method. After the beginning of the molybdenum ~ two", but after the human f-style, the touch panel has been widely used in various types of large and small electronic «talker can hand or stylus and other objects hit the panel on the side of t The contact wheel person is placed in the touch wheel, and the residual device set under the touch panel senses the purpose of the touch control electronic device. According to the sensing mechanism of the anvil, the touch panel can be classified into a resistive, capacitive=, acoustic, optical and electromagnetic touch panel; the type of the touch panel; Classification of touchpads, etc. ~ Recently, the emergence of a technology with multiple contacts acting on the touch panel to enable function input has made it easier for users to use electronic devices with touch panels. For the touch panel, the sensing method of the upper-contact position is performed in conjunction with the schematic description of the first figure. In the first figure, the sensing of the resistive touch panel includes a transparent substrate. U, a γ transparent conductive layer 12, a spacer layer, 3, - X transparent conductive layer 14 and - difficult to control 15. The transparent substrate u can be a glass panel '4 and ¥ transparent conductive layer 14, 12 and The transparent substrate η is formed in the same shape and is divided into materials such as indium tin oxide (ITO), indium oxide (ITO), and antimony oxide oxide (ΑΤΟ), and has a (four) resistance value on the entire surface thereof. In addition, the '5 Hz spacer layer 13 is sandwiched between the X and Υ transparent conductive layer 14 Between 12, 200928936 is used to make the X and γ transparent guides @ i 4 〇 month ¥ electric layer 14, 12 are insulated from each other. In actual operation, the X and Υ transparent conductive layers 14, 12 - The γ-to-side sides are alternately electrically connected through the external wires 15 to be externally connected to the ground, and the external side is connected to the ground, whereby the source = £ source 16 is formed on the 乂 and the transparent conductive layer. And the direction gradient on the potential gradient is reversed, and there is a current 〖produces a drop of 1/(, at this time χ and Υ transparent conductive layer, 12 - not electrical _ to external power (four), 16 of the two X Or Ο 电 is electrically connected to the controller 15 through the through-external lead 16. J° In detail, it is assumed that the user of the curry acts on the position of the resistor 1. When the user is at the contact Τ4Τ(4) On the electric (4) touch panel, the transparent conductive layer 12 at the contact 稍微 is slightly concave and is in contact with the transparent transparent snow Μ. At this time, the contact X is closest to the two X and the Υ The touch can be imagined as a virtual wire train 18 and a virtual wire row 9 , and the virtual wire row 18 on the gamma transparent layer 12 has a gap between the contacts Etc. = R1 and R2' and the contact ρ on the X transparent conductive layer 14 separates the dummy wires into two impedances R3 and R4. At this time, the equivalent impedances t and R4 on the transparent conductive layer 14 are electrically transferred. Connected to the controller 15, and the equivalent impedance and the impedance of the virtual conductor string 18 are large due to the transmission of the (four) conductors 16 and the control 15 electrical _, and no current flows through. Since the γ transparent conductive layer 12 The resistance system is evenly distributed, so the controller 丨5 can know the position of the ρ axis of the contact ρ on the γ transparent conductive layer 12 by comparing the two impedances R 丨 and R 2 . Similarly, the Υ transparent conductive layer 12 When the controller 15 is electrically coupled to the external voltage source π, the controller 15 obtains the parallel position of the contact P on the X transparent conductive layer 14 by the equivalent impedance illusion and the R4 on the virtual wire array 18. However, the resistive touch panel is not suitable for multi-contact function input. 6 200928936 Now the second picture shows the sound, heart '°. Assume that the two input points P1(xl, yi) and P2(x2, y2) are applied to the resistive touch panel, ^ π n± ,. There is another point of knowledge P3 (xl, y2) and P4 (x2, yl When the virtual P2° and the Ρ·Γ皮 act on the resistive touch panel, the two sets of input points P1 ', 2 and P3 and p4 are subtracted to 丨丨 v v, so the two sets of inputs - P = two Block _~2, ... For the above reasons n' is the controller 15 respectively. Spotted touch ± Μ to sense the position of the single contact on the resistive touch panel and the eve contact - force energy _ financial method (four) mention (four) necessary.
