As is known, the structure of a general touch panel mainly includes two planar conductive films arranged to face each other with a gap of one. The conductive film above is usually arranged on the surface of a transparent transparent film. The lower conductive layer is provided on the surface of a transparent glass substrate with a hard material, and a plurality of bump-shaped spacers are provided between the two surfaces arranged opposite to each other, leaving a gap in the sighing area of the conductive film. 'And apply adhesive on the periphery of the ring in the Yanhai area to seal the two together. Usually, in the manufacturing process of the touch panel, square and mouth items will inevitably be added in the towel. The static electricity remaining on each layer of insulation sheet will cause interference to the signal transmission of the touch panel, and the input result will be incorrect if the interference is severe. (Mobile phone 4) When used in combination, it will cause annoying noise interference, which will affect the communication quality. In addition, the touch panel is installed in front of the display screen. During use, it is repeatedly affected by the photoelectric signal (radiation) of the display screen , Will lead the panel residual static electricity caused by electromagnetic interference (〖〖16 (3 meter square Magnetic Interference, referred ΕΜΙ) phenomenon; therefore how to prevent static electricity or just 1
