Problems solved by technology

The yellow light process needs to make a corresponding photomask, and make a corresponding photoresist pattern through steps such as exposure and development. The process is complicated, and the manufacturing cost and mold opening cost are high.
[0005] The above problems lead to high production costs of high-quality touch screens, so that the cost of terminal products equipped with corresponding touch screens remains high, which greatly restricts the development of the industry

Embodiment Construction

[0024] The present invention will be further specifically described below in conjunction with the accompanying drawings and embodiments.

[0025] A method for manufacturing a touch screen for improving etching marks comprises the following steps:

[0026] Step 1: Provide a composite screen, the mesh area of ​​the composite screen is composed of a polyester mesh on the periphery and a steel wire mesh in the middle, wherein the mesh of the polyester mesh is 80-200 mesh, and the wire The diameter is 15-25 μm; the mesh number of the steel wire mesh is 420-520 mesh, the wire diameter is 12-20 μm, and the opening angle is 45°; the steel wire mesh area has several coatings arranged in strips and arranged in parallel at intervals area, the gap between adjacent coating areas forms a slurry leakage area, wherein the width of the coating area is 0.07-0.15 mm; the area ratio of the polyester mesh to the steel wire mesh is 1-5:1;

[0027] Step 2: Provide a touch screen substrate, the touc...

Abstract

The invention discloses a touch screen manufacturing method for improving etching traces. It is to make a composite screen composed of a polyester mesh located on the periphery and a steel wire mesh located in the middle, and then use acid-resistant ink TPER‑5200 to cooperate with the composite screen to print through the screen. The process forms a shielding layer with a gap of 0.07-0.15 mm, and then etches to form an electrode pattern with a corresponding gap. Etching traces of this width are difficult to be detected by the naked eye, thus realizing the shadow removal effect without the shadow removal coating, avoiding the problems of light transmittance and chromatic aberration caused by the shadow removal coating, and compared with the shadow removal substrate , the material cost is reduced by 60-70%; compared with the yellow light process, the production cycle is shorter, the manufacturing cost is low, and the same manufacturing precision as the yellow light process can be achieved, economical and practical, suitable for popularization and application.

Description

technical field [0001] The invention relates to a touch screen manufacturing technology, in particular to a touch screen manufacturing method for improving etching traces. Background technique [0002] The touch screen pattern is usually an array structure formed by the first electrode strips arranged along the first direction and the second electrode strips arranged along the second direction. It is formed by etching the entire surface or double-sided electrode materials. The industry standard gap is normally about 0.3mm. Due to the difference in electrode material and substrate reflectivity, the etching traces of this wide gap will be captured by the human eye, that is, the naked eye will see the touch screen graphics, and the visual experience is poor. [0003] In order to reduce the visual contrast and achieve the effect of shadow elimination, the conventional method is to perform shadow elimination coating treatment, especially for the case where the first electrode str...
