Flexible touch control mother board, manufacturing method thereof, flexible touch control board and touch control panel

Abstract

The embodiments of the present invention provide a flexible touch control mother board, a manufacturing method thereof, a flexible touch control board and a touch control panel, relating to the technical field of display, able to reduce the square resistance and improve the stress of a film layer at the same time, to prevent the poor bubbling and to improve the product quality rate. The preparation method includes: patterning a first transparent conductive layer formed on a flexible film to form first and second electrodes; and forming a first transparent conductive layer by a plurality of deposited first transparent conductive films, wherein the deposited first transparent conductive film of the first layer has a thickness of 15-45 nm, and the total thickness of the plurality of the first transparent conductive films is 120-200 nm.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a flexible touch mother board and a preparation method, a flexible touch substrate, and a touch panel. Background technique [0002] With the gradual development of flexible touch display products with narrow bezels and no bezels, the space for flexible touch electrodes (i.e. Sensors) to be wired at the edges of the bezels will be further reduced. The preparation process of the Sensors is required to achieve a better display area (i.e. Low channel impedance to reduce surface resistance (or square resistance). The symbol of square resistance is Rs, and the expression is Rs=ρ / t; where ρ is the resistivity of the electrode material, and t is the thickness of the electrode. [0003] Sensors are usually made of ITO (Indium Tin Oxide, indium tin oxide) transparent conductive materials. At present, the ITO square resistance commonly used in the industry is 100Ω / □ (symbol "□" means sq...
