Problems solved by technology

like figure 2 The design of the polymer conductive film 212 formed on the transparent substrate 210 has better flexibility, and will not change the color tone of the image due to the yellowish color, and because the normal pressure coating process is adopted, the cost is relatively low. figure 1 The known design shown is low; however, the conductive polymer film 212 has inherently poor conductivity and high surface contact resistance, which will cause line drawing signal drift and poor reliability when applied to touch panel products The problem

Abstract

A touch panel is provided, comprising a first and a second electrode substrates opposite to one another and jointed by an adhesive to keep a gap. The first or second electrode substrate is provided with a composite transparent conductive layer having a polymeric conductive film and a non-polymeric conductive film bonded with each other to provide better flexibility and increase the drawable time of line, wherein the non-polymeric conductive film is capable of increasing the conductivity and reducing the surface contact impedance.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel with an improved structure of a transparent conductive film with good properties. Background technique [0002] figure 1 It is a schematic diagram showing a conventional touch panel 100 design. Such as figure 1 As shown, the touch panel 100 includes an upper electrode substrate 102 and a lower electrode substrate 104 oppositely arranged, the upper electrode substrate 102 includes a transparent substrate 110, an ITO conductive film 112 and a signal transmission line 114 formed on the transparent substrate 110, the lower The electrode substrate 104 includes a transparent substrate 120 , an ITO conductive film 122 and signal transmission lines 124 formed on the transparent substrate 120 , and the upper electrode substrate 102 and the lower electrode substrate 104 can be joined by an adhesive AH. [0003] Such as figure 1 According to the design, the ITO conductive films 112...
