New description: [New technical field] The present invention relates to a sensing structure of a touch panel, in particular to a sensing structure of a capacitive touch panel and a touch panel including the same . [Prior Art] ^ At present, various electronic devices use touch technology as their input method, so that users can read information or transmit information by simply pressing the display panel with a finger or a stylus. The processing can eliminate the buttons, keyboard or slider that must be configured on the traditional electronic device. Touch panels are mainly classified into resistive, capacitive, infrared, and ultrasonic based on their sensing principles. Infrared and ultrasonic touch panels are attached to one side of the X and Y axes of the screen. Set the infrared or ultrasonic emission source and install the receiving source on the other side. When the user touches the screen, the movement of the infrared or ultrasonic wave is disturbed. The measurement and confirmation are subject to φ, and the interference coordinate position is the touch input. . The resistive touch panel is formed by laminating two sets of indium tin oxide (ITO) conductive films. After the upper and lower electrodes are turned on by pressure, the position of the contact point is calculated by the controller detecting the voltage change of the panel. To enter. As for the capacitive touch panel, it is composed of transparent glass coated with oxidized metal on the surface, and the voltage is supplied from four corners thereof to form a uniform electric field on the surface of the glass, and the capacitance generated by the electrostatic reaction between the user's finger and the electric field is used. Change to detect the input coordinates. Capacitive touch panels have the advantages of dustproof, fireproof, scratch-resistant and high-resolution M344522. However, they are susceptible to static electricity or humidity, causing misjudgment of motion or touch position. Therefore, to improve the sensitivity of capacitive touch panels. It is difficult to design the structure and the corresponding circuit, so there is still a need to break through the cost. The sensing electrodes of the conventional capacitive touch panel are arrays formed by a plurality of sensing structures, wherein each of the sensing structures is designed with ITO as a unit having a regular shape (for example, diamond shape), and only A single wire is electrically connected. In such a design, it is easy to interrupt the electrical connection of the sensing structure due to the problem of the wire, thereby causing an open circuit; in addition, since the conventional sensing array is composed of a plurality of planar sensing structures, in addition to the electrode material, Reduce the light transmittance of the touch panel and affect its performance. For the sake of the job, the applicant has carefully tested and researched it and proposed the "sensing structure and touch panel of the capacitive touch panel" in this case. This design adopts the design of the novel sensing structure and cooperates with the double-guide & bridge connection to avoid circuit interruption caused by the single-wire fault of the sensing structure, and can reduce the resistance of the device and reduce the resistance, and improve the touch. The transparency of the board.
