Description of the Invention [Technical Fields of the Invention] Panel The present invention relates to a touch panel, and more particularly to a capacitive touch panel. [Prior Art] A capacitive touch panel has an intuitive human-machine mutual purity. And a variety of light touch design features, used to be used in the public information line and instrument external input; I ©, to reduce the time required to establish a learning curve between the human-machine interface. In recent years, the somatosensory trend brought by Wii and iPh〇ne has made the intuitive and simple operation demand focus on the design elements of consumer products. The muscles use the capacitive touch panel to attract more people. Touch (multi_t_h) operation mode, which breaks away from the traditional single 彳 a _ mode, provides users with multiple control and natural gesture operation 'can be combined with software design for a variety of interactive operations, its powerful touch and perception The entertainment effect makes the capacitive touch panel help to spread rapidly in consumption, which has become the ultimate goal in the consumer market. In multi-touch operation mode +, multi-point recognition (multip〇im Cong Bu (4)) and tracing (tracking) two detection technologies are indispensable for multi-touch operation. Use the multi-point recognition technology to restore the two- or more-point touch target. T-trace technology can be used to analyze the multi-finger continuous movement trajectory to judge various operation gestures and perform their corresponding functions. With the multi-point identification and tracing detection technology, the connection between the electric valley touch panel and the user is more intuitive, and it also means that the multi-touch function will bring more interactive modes to the user interface. on. The electric valley touch panel utilizes a plurality of electrodes for generating an electric field, and the touch point is restored by detecting a change in the electric field by the finger when touched. The capacitive touch panel has a surface capacitive and a projected capacitive type 201140409 (projected capacitive), wherein the surface capacitive type refers to an electric field generated by the electrode that is flat on the surface of the touch panel. It means that the shape of the electric field is a three-dimensional space, which can be induced with the electric field without direct contact, so the future development has more potential than the surface capacitance type. Referring to FIG. 1 , the electrode design of the current projection type capacitive touch panel is illustrated, and the design includes a plurality of X-axis electrode serials Xi_X3 and a plurality of γ-axis electrode serials Y1-Y4. Each X-axis electrode train χι_χ3 includes a plurality of y-axis electrodes 10. Each of the x-axis electrode trains Υ1_Υ4 includes a plurality of γ-axis electrodes 2〇. The X-axis electrode 10 and the x-axis electrode 20 are formed in a rhombic shape by indium tin oxide (IT0). The wires 12, 22 are used to connect adjacent X-axis electrodes 10 and adjacent γ-axis electrodes 2A in the same series. According to the process technology, the X-axis electrode 1〇 and the γ-axis electrode 2〇 can be fabricated on the upper and lower layers, respectively, or in the same layer to maintain the single-layer structure design. The structure is simple and the application is widely used as the advantage of the XY-axis projection type capacitive touch panel. However, when the touch point is greater than or equal to two (four), the coordinates of the control point cannot be correctly restored. A corresponding virtual point is generated at the opposite corner of the touch point, so that the back-end system cannot determine the actual touch point, which is called a ghost point (gh〇st p〇int) phenomenon. Please refer to FIG. 2, which is a schematic diagram of the χ-γ-axis projection type capacitive touch panel using the χ_γ axis intersection point single-finger operation, and the back-end system can correctly restore the positioning touch point by the X-axis and the Υ-axis coordinate Α There will be no problems. Please refer to Figure 3 again, which shows the X-axis projection type capacitive touch panel using the χ_γ axis intersection point two-finger operation = schematic diagram. After adding the touch point 8, the back-end system uses the χ-axis and the γ-axis seat. '' σ is the original touch point A, Β, will also be combined into the other two non-touch virtual point A, 'so can not restore the correct touch point A, B position, can not be The touch operation performs multi-point tracing operation, which causes the multi-finger gesture function to be limited, and cannot use the multi-dimensional gesture operation to communicate with the product system ditch 201140409. Therefore, it is necessary to propose a solution to the above-mentioned capacitive touch panel that cannot achieve multi-point identification and tracing function due to ghost phenomenon.
