Static electricity often causes great damage to electronic products such as touch screens, causing the touch function to fail. Therefore, as a touch screen manufacturer, it is very necessary to improve the anti-static ability of the touch screen, especially the static electricity problem of the OGS structure with touch buttons. The structural design of static electricity protection is related to the quality, reliability and core competitiveness of the product. The BM used in OGS products is usually insulating photosensitive ink. It is very likely that the ink will be carbonized under the action of static electricity. After the ink is carbonized, it will become conductive, and the touch button TX and RX ITO channels are prone to short circuit. Utility Model Content
