preparation example Construction

[0034] As an aspect of the present invention, the preparation method of the patterned circuit structure includes:

[0035] (1) forming a transparent conductive material layer at least in the first set area on the surface of the substrate;

[0036] (2) forming an insulating material layer in a second set area on the surface of the substrate;

[0037] (3) Forming a circuit routing structure on the surface of the insulating material layer, and electrically connecting the circuit routing structure to the transparent conductive material layer, preferably, electrically connecting the circuit routing structure to the edge of the transparent conductive material layer.

[0038] In some specific application schemes, the second set area is arranged around the first set area, and at least the inner edge of the insulating material layer is joined to the outer edge of the transparent conductive material layer.

[0039] As one of the more preferred embodiments, the preparation method may al...

Embodiment 1

[0058] This embodiment firstly provides a transparent conductive film of carbon nanotubes with a 4.3-inch rhombic pattern covered on a substrate as a transparent conductive electrode. Continuous etching is carried out around the visible area, and the etching depth should reach the surface of the substrate or go deep into the interior of the substrate, so as to completely isolate the transparent conductive electrode in the visible area from the non-visible area. Through precise positioning, use flexographic printing to print epoxy resin outside the diamond pattern frame (that is, the visible area) and in the area where the silver line is printed (that is, the non-visible area), and dry it with hot air in an oven at 80°C. Screen printing prints silver paste on the surface of the cured epoxy resin to form circuit traces connected to the edge of the electrode material, and dries with hot air at 130°C to obtain a sensor for capacitive touch screens.

Embodiment 2

[0060] This embodiment firstly provides a transparent conductive film of silver nanowires with a 4.3-inch diamond pattern covered on a substrate as a transparent conductive electrode. Continuous etching is carried out around the visible area, and the etching depth should reach the surface of the substrate or go deep into the interior of the substrate, so as to completely isolate the transparent conductive electrode in the visible area from the non-visible area. Through precise positioning, use flexographic printing method to print silicone resin outside the rhombus pattern frame (that is, the visible area) and in the area where the silver line is printed (that is, the non-visible area), and dry it with hot air in an oven at 120 ° C. Screen printing prints silver paste on the surface of the cured silicone resin to form circuit traces connected to the edge of the electrode material, and dries with hot air at 130°C to obtain a sensor for capacitive touch screens.

Abstract

The invention discloses a graphical circuit structure, a manufacturing method thereof and application thereof. The technical scheme is that an insulation material layer is arranged in a covered mode in a zone outside a visible zone which is used for arranging of a transparent conducting electrode, especially in a zone for forming of a circuit routing structure, the circuit routing structure is formed on the surface of the insulation material layer, and the problems that patterning of a transparent conducting material in the zone for forming the circuit routing structure is not complete or has residual so that internal short circuit fault of the circuit routing structure happens and the like are avoided. Technology is simple, cost is low, large-scale implementation is easy, product performance can be effectively improved, product yield can be improved, and the graphical circuit structure can be widely used in photoelectricity devices and electronic equipment.

Description

technical field [0001] The invention particularly relates to a patterned circuit structure, its preparation method and application. Background technique [0002] With the popularity of smart phones, touch technology has become an important means to improve the efficiency of man-machine dialogue. Among many touch technologies, capacitive touch has been used in smart phones, notebooks, handheld computers, etc. Applications have been made on a range of terminals. [0003] As far as the structure of the capacitive touch screen is concerned, the patterned transparent conductive layer in the visible area and the connecting circuit in the non-visible area constitute the core of the entire touch circuit. In the design of the touch screen, the space occupied by the connecting circuit has a direct relationship with the frame width of the touch screen screen. Under the current requirement for a narrower touch screen design, that is, the smaller the frame design, the better, it is nec...
