New description: [New technology field] [0001] This creation is about a touch panel, especially a capacitive touch panel. [Prior Art] [00〇2] The touch panel was developed by the US military for military use in the 1970s. It was transferred to civilian use in the 1980s and developed into various uses. At the present stage, due to the rise of wireless networks, traditional input devices such as keyboards, mice, trackballs, etc. have not been able to meet the market demand. Touch panels have been characterized by simple operation and easy to use. Widely used in various consumer electronic terminal products, and from the role of the past supporting role, has become a key component. [0003] Currently, the common touch panels on the market can be divided into two types according to the physical principle of detecting touch points, namely a resistive screen and a capacitive screen. Resistive screen is the oldest, most versatile and cheapest touch panel. It is mainly made up of two layers of indium tin oxide (Indium Tin Oxide, ΙΤ0). It is lightly transmitted through the contact (styius). The upper and lower electrodes are turned on by the pressure generated on time, and the position of the contact point is measured by the controller to detect the voltage drop of the panel. Resistive screens are used in a wide variety of products, such as Mp3 players and smart phones, due to their low production cost. However, since the resistive type is difficult to be a two-layer structure, its thickness cannot be greatly reduced to be suitable for smart phones and (4) dispensers that are demanding in the market; in addition, in order to avoid pressure on the touch panel due to contact pressing Injury caused by the body, the curtain itself will be coated at least - layer protection "material, form number A0101 page 3 / a total of 19 pages 100 years October ί8 day nuclear page [0005] This system makes the screen's transparency lower . In order to solve the shortcomings of the resistive touch panel, the capacitive touch panel has become the focus of technology research and development. A capacitive touch panel is a capacitance change generated by electrostatic coupling between an array of electrodes and a human body (such as a finger) or a grounded contact. The induced current is detected from the generated induced current. 0006] Referring to the first and second figures, respectively, a cross-sectional view of a conventional capacitive touch panel and a plan view of the face.

The transparent cover 20 can be used to protect the touch module 10 from damage caused by pressure, and at the same time prevent moisture or fine dust from adhering to the circuit board 110, thereby causing the capacitive touch. The overall use form of the control panel 1 is A0101, page 9 / 19 pages, M418340, October 18, 100, the shuttle is being replaced - k life is shortened. [0028] Referring to the sixth figure, a rear view of the capacitive touch panel of the second embodiment of the present invention is shown. The capacitive touch panel 1a of the present embodiment is substantially the same as the first embodiment described above, except that the two conductive elements 128a of the embodiment are conductive films, and the two conductive elements 128a are respectively disposed on the two pads 126 and The circuit layers 115 (as shown in the fourth figure) are used to electrically connect the circuit layer 115 and the light emitting unit 130 disposed on the two pads 124 and electrically connected to the two pads 126. In the present embodiment, the conductive film is exemplified by a carbon film, and the actual implementation is not limited thereto. The conductive film can be disposed between the pad 124 and the circuit layer 11 5 through a printing process. [0029] Referring to the seventh figure, a rear view of the capacitive touch panel of the third embodiment of the present invention is shown. The capacitive touch panel lb of the present embodiment is substantially the same as the first embodiment described above, except that the two conductive elements 128b are respectively resistors, and preferably, zero ohm resistors, the two conductive elements 128b The two pads 126 and the circuit layer 115 (shown in FIG. 4 ) are respectively disposed to electrically connect the circuit layer 115 and the two pads 126 and are electrically connected to the two pads 126 . The light-emitting unit 130 is integrated with the sensing element 120 and the light-emitting unit 130 on the second surface 114 of the circuit board 110, as compared with the prior art. The circuit board with dual circuit layers can effectively reduce the manufacturing cost of the circuit board 110 and make the manufacturing process easier. In addition, the overall thickness of the capacitive touch panel can be effectively reduced to be suitable for Lightweight and demanding electronic devices. Form number A0101
