Patterned transparent conductive film

Abstract

A patterned transparent conductive film is provided. The patterned transparent conductive film comprises a substrate, a first conductive layer and a second conductive layer; the first conductive layer includes a first conductive region and a first insulating region; the second conductive layer includes a second conductive region and a second insulating region; the first conductive region and the second conductive region both comprise a plurality of metal grids formed by metal wires, wherein the plurality of metal grids are embedded random metal grids with irregular shape; the probability density of the slope of the metal wires of the first conductive region being adjacent to a horizontal direction is larger than the probability density of the slope of the metal wires of the first conductive region being adjacent to a longitudinal direction; the probability density of the slope of the metal wires of the second conductive region being adjacent to a longitudinal direction is larger than the probability density of the slope of the metal wires of the second conductive region being adjacent to a horizontal direction; and the second conductive layer and the first conductive layer are stacked in the thickness direction of the substrate and are separated and insulated from each other, and stacked metal grids, which is formed after stacking, are evenly distributed in each angle. Light transmittance is increased with conductive performance unchanged, and the metal grids of the two layers of conductive films after the stacking are evenly distributed in each angle, and therefore, a moire fringe phenomenon can be eliminated.

Description

technical field [0001] The invention relates to the technical field of conductive films, in particular to a patterned transparent conductive film. Background technique [0002] Transparent conductive film is a kind of conductive film with good conductivity and high light transmittance in the visible light band. At present, transparent conductive films have been widely used in fields such as flat panel displays, photovoltaic devices, touch panels, and electromagnetic shielding, and have an extremely broad market space. [0003] In the traditional mobile phone touch screen, in order to reduce the thickness and weight of the mobile phone, a flexible patterned transparent conductive film is mostly used; in general touch screens, most of the touch screens need to use two transparent conductive films to form the upper and lower electrodes to complete the touch function. However, when two transparent conductive films are combined up and down, the light transmittance will be furthe...
