Description of the Invention: [Technical Field] The present invention relates to a resistive touch panel, and more particularly to a touch panel having an electrostatic protection design. [Previous technology] Touch panels have been widely used in electronic devices such as Point of Sales (P0S), large-scale video games, and handheld electronic products. In particular, the end point sales system is more common in large-scale Stores, department stores, restaurants and other places. Static electricity (ESD, Electrostat Statie Discharge) also causes static electricity to accumulate in the touch panel. The presence of static electricity can cause some problems in the touch panel. Take the endpoint sales system as an example. If the touch screen has static electricity accumulation, it may accelerate the touch panel's mean time between failures (MTBF, Mean Time Between FaUures). Aging, it is also easy to cause the machine to crash in the use of the system, resulting in inconvenient use, and even more risk of data loss. In addition, if excessive static electricity is stored on the touch panel, the user may be shocked during operation. However, the touch panel on the market does not provide protection against static electricity problems, so the existing touch panel still has room for improvement. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a touch panel having an electrostatic protection design. Another object of the present invention is to provide an electronic device of the 200901013 having the aforementioned touch panel.

The touch panel may further include a flexible circuit board having a plurality of pins, and one of the pins is electrically connected to the first electrostatic protection path to transfer the static electricity to the touch panel. The touch panel can further include a conductive bezel disposed on an edge of the transparent substrate and electrically connected to the second electrostatic protection path. The electronic device of the present invention comprises a touch panel, a control circuit having a grounding line, and a grounding surface, wherein the end of the I-pin of the flexible circuit board is electrically connected to the first-electrostatic protection path, and The end is electrically connected to the grounding line of the control circuit, and the grounding line is electrically connected to the grounding circuit of the power source to conduct static electricity out of the touch panel; in addition, the material power frame is electrically connected to the grounding surface, and the static electricity is also Conducting the touch panel. [Embodiment] The foregoing and other technical contents, features and advantages of the present invention will be described in the following detailed description of the preferred embodiments of the drawings. Θ 200901013 Referring to FIG. 1 ' FIG. 2 and FIG. 3 ′′, a preferred embodiment of the touch panel having the electrostatic protection design of the present invention, the touch panel 10 includes a transparent substrate 1 , a vapor permeable film 2 , and a plurality of spacers 3 . A flexible circuit board 4, a conductive edge 8 and a second electrostatic protection path 92. The transparent substrate 1 has a glass base layer 12 and a conductive layer 11 coated on the glass base layer U. In the present embodiment, the conductive layer u is an oxidized samarium (yttrium) film layer. The transparent film 2 has a polyethylene terephthalate (PET) base layer 22 and a conductive layer 21 (oxidized tin-bismuth layer) coated on the pET base layer. A circuit diagram f 5 is formed on the conductive layer U, including an original signal path 51 and an insulating line 52 disposed on the periphery of the original signal path 51. A first electrostatic protection path 91 is disposed on the periphery of the insulated circuit 52. The first electrostatic protection path 91 can be formed by printing silver paste. After the circuit pattern 5 and the first static electricity protection path 91 are formed, the spacer 3, the silver paste 61, the insulating glue 62 and the sealant 63 are sequentially printed on the conductive layer u, and on the other hand, the conductive layer of the transparent film 2 is also formed. 21 is also sequentially printed with silver glue 61, insulating glue 62 and frame glue 63. After the frame glue 63 is printed, the transparent substrate 1 and the transparent sheet 2 are aligned, and the flexible circuit board 4 is adhered to the transparent layer. Between the substrate 1 and the transparent film 2. The flexible circuit board 4 is provided with six pins (pm) 41 to 46, and generally only five of the pins 41 to 45 are used, and the functions of the pins 41 to 45 are well known to those skilled in the art. This is not described in detail, and the present invention utilizes generally unused pins 46 to form an electrical connection with the first electrostatic protection path 91 for conducting static electricity. Referring to FIG. 1, FIG. 3 and FIG. 4, a second electrostatic protection path 92 is formed on the surface 13 on the other side of the glass base layer 12.

The static electricity on the surface 13 of the glass substrate 12 can be quickly conducted to the metal bead 81 & conductive foam 82 by the second electrostatic protection path 92. The metal bead 81 and the conductive foam 82 can conduct static electricity to the grounding surface of the electronic device 7 (not shown), and the grounding surface can be a metal casing or a frame, so that static electricity can be conducted out of the touch panel 1 .

The electrical connection is such that the static electricity on the transparent substrate 1 on the side of the conductive layer ii can be conducted out of the touch panel 10 via the first electrostatic protection path 91, the pin 46, the ground line of the control circuit, and the ground return of the power source. The second electrostatic protection path can be electrically connected to the ground plane of the electronic device 7 in which the touch panel 1G is assembled, so that the second static protection path 92 forms a return path and is transparent. Substrate! The static electricity on the glass substrate η surface 13 can be conducted to the ground plane by the second static electricity protection path 92, and the static electricity is conducted out of the touch panel 1G.
