Today, touch panels are mainly classified into resistive and capacitive according to their different sensing principles. Four types, such as electromagnetic type and optical type, the capacitive touch panel structure is widely used in dustproof, fireproof and high resolution. The principle of the capacitive touch panel is mainly based on the change of capacitance. To confirm the position of the contact point, a capacitive electrical change is made between the electrodes by using a touch object (such as a conductor such as a finger) to determine the coordinates of the contact point. Capacitive touch panels are gradually becoming the mainstream in touch technology and are used in various electronic information products, such as mobile phones, tablets, walkmans, handheld electronic devices (devices), various displays, monitors, etc. The electronic information products of the capacitive touch panels have the principle of sensing the change of the capacitance value formed by the weak current of the human body to achieve the purpose of the touch, thereby measuring the position change and the selection state of the finger, and achieving The purpose of manipulation. The general capacitive touch panel is mainly used as a double-layer touch panel, and the double-layer touch panel is mounted on each transparent conductive substrate for multi-screen printing process or yellow etching process. Indium Oxide 1012032774-0 Page 3 / 9 pages M437497 Tin (ITO) layer, the material of this type of transparent conductive substrate is mostly glass, because the transparent conductive substrate has a high unit price, it will repetitively consume more production materials during manufacturing. When a defective product is generated in the touch panel process, the entire touch panel must be scrapped and cannot be recycled, thereby causing waste of cost, and each transparent conductive substrate needs to have the indium tin oxide (ΙΤ0) layer separately. The multi-pass screen printing process or the yellow etching process is carried out and the manufacturing steps are cumbersome and the manufacturing cost is greatly increased at the same time. In addition, the above-mentioned yellow light micro-shadowing method not only requires expensive equipment, but also relatively increases the overall production cost, and the components and developing solutions used are chemical solutions harmful to the human body, which not only have a serious impact on the health of the operators on the site, but also It causes serious pollution to the environment and ecology; therefore, it has the following disadvantages: 1. The manufacturing steps are cumbersome; 2. The manufacturing cost is. Therefore, how to solve the above problems and shortcomings, that is, the creators of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.
