Detailed Description
In order to make the technical problems, the adopted technical solutions and the achieved technical effects of the present invention clearer, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, when the conventional capacitive screen is used for a 0-touch complete machine, an insulating layer 1 'needs to be additionally attached, that is, the structure is that the insulating layer 1', a first bonding layer 2', a first conductive film 3', a second bonding layer 4', a second conductive film 5', a third bonding layer 6 'and a cover plate 7' are stacked. Wherein the insulation layer 1' may be selected from an AG film or a PC film. When the insulating layer 1' is made of a PC film, the liquid crystal display panel needs to have a frosted effect because the surface of the PC film is smooth, and if the liquid crystal display panel is also smooth, water ripples, newton's rings and the like are generated when the two smooth surfaces are in contact with each other, which will interfere with the display effect, while when the insulating layer 1' is made of an AG film, the liquid crystal display panel can be freely selected. However, whether the AG film or the PC film is selected for the insulating layer 1', an adhesive layer three 6' needs to be provided on the conductive film two 5 'to perform adhesion of the insulating layer 1', which not only increases the process and material consumption, resulting in an increase in cost, but also increases the risk of defective processing.
In order to solve the problem, as shown in fig. 2 and fig. 3, the present invention provides a capacitive screen, which includes a first conductive film 1, a first adhesive layer 2, a second conductive film 3, a second adhesive layer 4 and a glass cover plate 5 laminated together. Different from the conventional capacitive screen, the first conductive film 1 includes a first substrate 12, one surface of the first substrate 12 is provided with a first conductive circuit 11, the other surface is provided with an AG frosting layer 13, the AG frosting layer 13 is located on one surface of the first substrate 12 away from the first adhesive layer 2, and a hardening layer (not shown in the figure) is further disposed on one surface of the AG frosting layer 13 away from the first substrate 12. By enabling the first conductive film 1 to have the AG frosting effect, the process of adhering the AG film to the other surface of the first conductive film 1 by using the adhesive layer can be omitted, the purchase cost is reduced, the bad risk in the processing process is reduced, and the assembly requirement of the whole display panel is reduced. The hardness of the first conductive film 1 can be enhanced by the hardened layer, the surface of the first conductive film 1 is not easy to be scratched by a manufacturing process, and in the assembling process, even if the first conductive film is extruded by a sharp object, functional obstacles are not easy to occur on the built-in conductive circuit.

And for the first conducting layer of the panel black frame area of the capacitive screen, a peripheral conducting circuit can be formed through processing of a laser etching process. Because the AG frosted layer 13 is damaged synchronously if the laser etching process is selected for the visible area, thereby affecting the optical and visual effects, and the signal line of the visible area is etched by using the etching paste process, the acid-resistant process or the yellow light process, the AG frosted layer 13 on the other side of the first conductive film 1 can be effectively protected from being damaged, and the AG frosted layer 13 on the back side of the silver line does not need to be controlled because the silver line is not in the visible area when the panel black frame area is processed by using the laser etching process.

Optionally, the manufacturing process of the first conductive film 1 is to process the other surface of the first conductive film 1 to form an AG frosted layer 13, then attach and protect the processed AG frosted layer 13 through a protective film, and further process the first conductive line 11 on one surface of the first substrate 12.
