Embodiment 1

[0037] The embodiment of the present invention provides a method for preparing a flexible touch mother board, such as figure 2 As shown, the preparation method includes:

[0038] Step S01: Perform a patterning process on the first transparent conductive layer formed on the flexible film to form a plurality of intersecting first electrodes and second electrodes in the display area; wherein the first transparent conductive layer is deposited multiple times The thickness of the first transparent conductive film deposited is 15-45nm, and the total thickness of the first transparent conductive film is 120-200nm.

[0039] It should be noted that, first, the above-mentioned flexible touch mother board provided by the embodiment of the present invention includes a plurality of display areas, which can be divided into multiple small pieces, that is, a single flexible touch substrate is formed. Each touch substrate includes a display area, so that mass production of flexible touch substrates...

Embodiment 2

[0088] Further, an embodiment of the present invention also provides a flexible touch mother board, which is made by the above-mentioned preparation method. It can obtain a relatively flat surface while having a lower electrode channel impedance, and is the first in the industry to realize the Roll to Sheet low square resistance process.

Embodiment 3

[0090] Further, an embodiment of the present invention also provides a flexible touch substrate, which is any one of a plurality of sub-substrates cut from the above-mentioned flexible touch mother board.

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...
