Touch screen manufacturing technology capable of improving etch marks

Abstract

The invention discloses a touch screen manufacturing technology capable of improving etch marks. The technology comprises the steps that a composite screen composited by a polyester mesh located at the periphery and a steel wire mesh located in the middle is manufactured; acid-resisting ink TPER-5200 is adopted to cooperate with the composite screen to form shielding layers with the interval of 0.07-0.15 mm through a screen printing process; and then etching is conducted to form electrode patterns with the corresponding interval. The etching marks with the width are difficult to be detected bynaked eyes, therefore, a shadow elimination effect is achieved on the condition that a shadow elimination coating is not needed, the problems of transmittance and chromatic aberration which are brought by the shadow elimination coating are avoided, and compared with a shadow elimination base material, the material cost of the method is reduced by 60%-70%; and compared with a yellow light manufacturing process, the technology is short in production cycle, low in manufacturing cost, capable of achieving the same manufacturing precision as the yellow light manufacturing process, economical, practical and suitable for application and popularization.

Description

technical field [0001] The invention relates to a touch screen manufacturing technology, in particular to a touch screen manufacturing process 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 st...

AI Technical Summary

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
