New Description: [New Technology Field] This creation relates to the field of capacitive touch screen/touchpad technology, especially to the field of contact positioning technology of capacitive touch screen/touchpad. [Prior Art] The capacitive touch screen/touchpad works by the current sensing of the human body. The conventional capacitive touch screen/touchpad has a substrate with X/Y upper and lower layers of IT〇 (transparent conductive material). line. The working principle is to detect the change amount of the contact capacitance value of the χ γ axis of the upper and lower layers, and determine the position of the finger touch in the 方向 axis direction after the touch 1C processing, thereby determining the touch point of the touch screen on the touch screen/touch panel. Point coordinates. Since the existing capacitive touch screen/touch panel needs to be provided with Χ/Υ two layers of ΙΤ〇 (transparent conductive material) lines, the manufacturing process is high, the production cost is high, and the price is far more than the current large-scale resistive touch screen/touch pad. Expensive, not conducive to the large-scale promotion and application of capacitive touch screen / touchpad. [New content] The purpose of this creation is to provide a one-dimensional contact positioning capacitive touch screen/touch panel for the shortcomings of the prior art, which has the characteristics of less manufacturing process and low production cost. For the above purposes, the one-dimensional contact positioning capacitive touch screen/touch panel of the present invention comprises a substrate, a metal layer, and a touch 1C, wherein the substrate is provided with a single layer of germanium. Each of the turns of the line, the tantalum line has a determined capacitance value and forms an alternating cross-arrangement, but not electrically connected patterns. 3 W W-shaped pattern (4) and B1 to B4); the rib lines shown in Fig. 3 form solid rectangular patterns (A1 to A4 and B1 to B4); the ITO lines shown in Fig. 4 form a plurality of --angle patterns (A1) ~A4, and B1~B4, C1C4, D1~D4)'. The ITO lines touched by the hand are generally between three and six. Now the finger touches the point of the towel and the silk shows that the center of the sugar center is determined by two lines of ιτ〇: Firstly, the position in the γ-axis direction is determined. This position is determined by whether the capacitance of the touch c changes according to the capacitance values on the two turns; after the position of the x-axis is determined, the two twist lines are determined. The position of the touch on the X-axis; assuming that the total capacitance of the two turns generated by the finger touch is Ca+b, regardless of the position of the two wires touched, the total value of the capacitance CA+B is a fine value. As the position of the two ITO lines is driven by the finger on the x-axis, the capacitance values CA and Q on the two rib lines are changed. The touch IC 30 determines the ratio of the capacitance values of the two ITO lines to the total capacitance value. The finger touches the position of the center of gravity of the contact in the X-axis direction, so that the touch of the contact can be determined by the touch of the determined χγ axis. It should be noted that the principle of this creation applies to all capacitive touch positioning.
