Background
In recent years, the application range of touch panels is becoming wider, and more electronic products have been added to the touch panels to provide functions for users to directly perform operations or issue commands, and among them, the demand for flexible touch panels is increasing.
However, the copper metal mesh always has optical problems of too high yellowing index (b value) and light reflection, and the copper light reflection of the regular mesh pattern is easy to generate constructive interference to form a so-called moire (moire effect) problem, so that in order to avoid the optical problem generated by the copper metal mesh from affecting the light transmittance of the conductive film, the copper metal mesh is usually blackened to reduce the visibility of the conductive film, or the line width of the copper metal mesh is further reduced. However, the blackening process or the reduction of the line width of the grid increases the steps for preparing the conductive film and reduces the yield of the product, and the production cost also increases.
The nano silver wire has high conductivity and excellent flexibility, but if the nano silver wire is used to form the conductive layer, the nano silver can generate surface plasma resonance effect, so that the nano silver wire can absorb ultraviolet light in the wavelength range of 320nm to 420nm, and the conductive film prepared by the nano silver wire can be yellow, thereby affecting the color of the image output by the display panel.
Therefore, there is a need for a novel transparent conductive film and a touch panel comprising the same, so as to improve the optical defects of the flexible transparent conductive film prepared by using a copper metal mesh or a nano silver wire layer, improve the yield of the product, and provide excellent conductive characteristics.
