Transparent conductive film

Abstract

The invention discloses a transparent conductive film. The transparent conductive film comprises a transparent bearing layer and a plurality of conductive areas and a plurality of color matching areaswhich are alternately arranged on the transparent bearing layer, each conductive area comprises conductive grids which communicate with each other, each color matching area comprises color matching grids, and gaps are formed between the conductive grids and the color matching grids, and the conductive grids and the color matching grids are mutually insulated, wherein the widths of the grid linesof the color matching grids are larger than the widths of the grid lines of the conductive grids. Through arrangement of the widening of the grid lines of the color matching grids, the decreasing of the duty ratio of the color matching grids in the color matching area caused by gaps is compensated, the light transmittance of the conductive area and the color matching area is balanced, and the visual effect of the overall appearance of the transparent conductive film is guaranteed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a transparent conductive film. Background technique [0002] The 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 sensors, and electromagnetic shielding, and have an extremely broad market space. The material for preparing transparent conductive films is generally Indium Tin Oxide (ITO), but in most practical applications such as touch screens, the preparation of transparent conductive films requires patterning of ITO to form fixed conductive areas on the substrate surface and insulating areas. However, the patterning process of ITO often requires multiple processes such as exposure, imaging, etching, and cleaning, and the preparation process is relatively comp...

AI Technical Summary

Problems solved by technology

However, in general, in order to ensure the electrical insulation properties of the insulating area, gaps and intervals need to be set between the conductive area and the insulating area and between the grid lines of the insulating area, so that the light transmittance between the conductive area and the insulating area remains the same. There are subtle differences that affect the overall appearance of the transparent conductive film
