Problems solved by technology

[0005] The first purpose of the present invention is to provide a conductive film layer structure. In order to solve the problem of abnormal size due to the expansion and contraction of the screen, the actual position of the laser line directly hitting the conductive area is different from the actual position of the laser line on the CAD drawing. There are deviations, which may cause technical problems that may adversely affect the subsequent use of the manufactured touch screen

Embodiment 1

[0048] Such as Figure 1-4 As shown, the first embodiment provides a conductive film layer structure, including: a conductive film layer 100, the conductive film layer 100 includes a conductive area 200, a sensing area, and a plurality of test blocks used for laser line offset adjustment standards A plurality of test blocks are respectively arranged near the outer side of the conductive area 200; the test block adopts a structure adapted to the laser line, and the cooperation between the two can facilitate the adjustment of the relative offset between the two.

[0049] In this embodiment, the aforementioned "conductive material" can be conductive silver paste or be consistent with the material used in the sensing area; when conductive silver paste is used, the conductive area 200 can be referred to as a silver paste area.

[0050] In the conductive film layer structure, the conductive film layer 100 is provided with a plurality of test blocks for adjusting the reference of the laser...

Embodiment 2

[0064] The second embodiment provides a manufacturing method of the conductive film layer structure in the first embodiment, including the following steps:

[0065] (A) A conductive area 200 and a plurality of test blocks are printed on the upper or lower film of the conductive film layer 100, and a conductive material is printed in the conductive area 200;

[0066] (B) Make the laser line hit multiple test blocks, adjust the laser line and make the laser line align with each test block;

[0067] (C) The entire printed conductive material is etched.

[0068] It should be noted that in step (A), the test block and the conductive area 200 are printed at one time through a screen; in step (B), the laser device can make multiple laser lines hit the corresponding test at one time. Block position, the overall adjustment of the laser offset relative to the silver paste area.

[0069] Among them, the method of printing silver paste on the upper film and laser etching is similar to the method o...

Abstract

The invention provides an electric conduction film layer structure, a manufacture method thereof, and a touch screen, and relates to the technical field of touch display. The invention aims to solve the technical problems that adverse effects are generated in the subsequent use of the manufactured touch screen since a screen printing plate has harmomegathus, dimensions are abnormal and a practicalposition where a laser line is directly printed on an electric conduction area has a deviation with the practical position of the laser line on a CAD (Computer-Aided Design) drawing. The invention relates to the electric conduction layer structure, which comprises an electric conduction film layer, wherein the electric conduction film layer comprises an electric conduction area, an induction areaand a plurality of test blocks used for laser line deviation regulation criterions; a plurality of test blocks are respectively arranged on an outer side which is near the electric conduction area; the test blocks adopt a structure adaptive to the laser line; in addition, the test blocks and the laser line are cooperated to conveniently regulate a relative offset between the test blocks and the laser line. According to the electric conduction film layer structure, the manufacture method thereof and the touch screen, the deviation, which is relative to silver paste, of laser can be regulated.

Description

Technical field [0001] The present invention relates to the technical field of touch display, in particular to a conductive film layer structure, a manufacturing method thereof, and a touch screen. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. As a new type of computer input device, touch screen is currently the simplest, convenient and natural way of human-computer interaction. Nowadays, touch screens have a wide range of applications, and their main uses include: corporate meetings, commercial advertisements, education and teaching, smart queries, exhibitions, smart homes, smart games, etc. [0003] Currently, there are many types of touch screens. Among them, according to the working principle of the touch screen and the classification of the medium for transmitting information, the touch screen can be divided into four types, which are re...
