OGS captive touch panel and method for manufacturing same
The present invention provides an OGS capacitive touch panel, including a substrate, a touch control unit, an insulating layer, a conductor and a trace of the touch control unit, wherein the touch control unit and the insulating layer are arranged on a first surface of the substrate and the former is in the active area and the latter on the periphery of the capacitive touch panel; the trace of the touch control unit extends from the touch control unit on the first surface; on the periphery of the capacitive touch panel, the insulating layer partly covers the trace of the touch control unit, and the conductor is electrically connected to the trace of the touch control unit on the part of the trace of the touch control unit which is uncovered by the insulating layer. The method for manufacturing the OGS capacitive touch panel of the invention arranges the process of forming the insulating layer after the process of forming the touch control units and the traces of the touch control units. In the invention, the problem of color changing and insulativity deteriorating of the insulating layer, which is formed by general colored ink, gloss varnish or colored photo-sensitive resist, aroused by the poor high-temperature resistance is solved, and the difficulty in coating process and traces having to get over a step are avoided. The OGS capacitive touch panel of the invention is simple structured and reliable; its manufacturing method has less processes and is easy to carry on.
