Abstract

The invention discloses a manufacturing method of a monolithic touch control screen. The manufacturing method of the monolithic touch control screen aims to solve the problem of stress release in the cutting process after tempering of a glass base plate in the OGS touch control screen production process in the prior art to improve the yield of single screen cutting and production efficiency. The method includes a step of forming a first film layer on a provided base plate, wherein the first film layer comprises at least one hollow-out area and a protection film around each hollow-out area; a step of conducting tempering processing on the base plate to achieve the tempering of the corresponding area of each hollow-out area on the base plate; a step of removing the protection film on the base plate. According to the manufacturing method, the protection film is arranged on the glass base plate, the protection film area is not tempered when the glass base plate is tempered, stress release can not be generated in the cutting process, the cutting yield is improved, the process step is simple, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of touch screen manufacturing, in particular to a method for preparing a single-chip touch screen. Background technique [0002] One Glass Solution (OGS) is a technology that directly forms ITO conductive film and sensors on the protective glass. In this technology, a single piece of glass acts as both a protective glass and a touch sensor. The OGS touch screen has the advantages of simple structure, thin overall thickness, light weight, and high light transmittance. At the same time, the production cost is reduced due to the saving of a glass substrate and the bonding process. [0003] At present, in the production process of OGS touch screen, the glass substrate is usually tempered first, and then cut according to the design specifications of the single screen. Since the position to be cut has been tempered, the stress release during the cutting process of the single screen will cause cutting. Cracks appear when c...
