Double-sided patterned transparent conductive film and method for manufacturing the same
A double-sided patterned transparent conductive film includes an upper surface conductive layer ( 12 ) and a lower surface conductive layer ( 12 ). The upper surface conductive layer is a patterned trench network; the lower surface conductive layer is a full-surface trench network. A trench of the upper surface conductive layer is filled with conductive material ( 13 ), and a trench of the lower surface conductive layer is intermittently filled with conductive material ( 13 ). The double-sided patterned transparent conductive film has a high resolution, transmittance, independently adjustable square resistance and many other advantages, such that the transparent conductive film saves a cost of PET. According to the manufacturing method, the alignment is not needed for double-sided imprinting of a single flexible substrate, thus the process is simple, low cost, advantageous for industrial production.
