Embodiment Construction

[0025] Further description will be given below in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0026] The manufacturing method of this ultra-thin capacitive touch screen comprises the following steps:

[0027] (1) if Figure 1-a As shown, a peeling glue 2 is coated on the carrier 1, and the peeling glue 2 is an ultraviolet decomposing glue, such as a glue mixed with an acrylic resin with a reactive group and a multifunctional photosensitive resin.

[0028] (2) if Figure 1-b As shown, the thin glass sheet 3 is attached on the carrier plate 1 through the peeling glue 2;

[0029] (3) if Figure 1-c As shown, the touch circuit layer 4 is made on the thin glass sheet 3, and a protective layer can be further coated on the touch circuit layer 4, only the external port of the touch circuit layer 4 is exposed, and the protective layer can be transparent. The photosensitive resin coating can also be a non-transparent insulating lay...

Abstract

The invention discloses a manufacturing method for an ultrathin capacitive touch screen. The method comprises the steps of coating a carrier plate with stripping glue; attaching a thin glass sheet tothe carrier plate through the stripping glue; making a touch circuit layer on the thin glass sheet; performing lacerating and precision carving on a combined body of the carrier plate and the thin glass sheet; and soaking lacerated units in an etching chemical liquid for performing chemical polishing. Through cooperation of two aspects of reducing the probability of generating thin and small cracks and controlling a spreading trend of the thin and small cracks, the breakage probability of the thin glass sheet is greatly reduced in the thin glass sheet making process, so that the manufacturingyield of the capacitive touch screen is greatly increased.

Description

technical field [0001] The invention relates to a method for manufacturing a capacitive touch screen, in particular to a method for manufacturing an ultra-thin capacitive touch screen. Background technique [0002] The ultra-thin capacitive touch screen has a low thickness and a certain degree of flexibility, and can be applied to some electronic devices that require high thinness and lightness. [0003] Ultra-thin capacitive touch screens generally manufacture the touch circuit layer on an ultra-thin glass substrate with a thickness of 0.1-0.3 mm. [0004] In order to use general capacitive touch screen manufacturing equipment to make this ultra-thin capacitive touch screen, it is generally necessary to attach an ultra-thin glass substrate to a platform, then make a touch circuit layer on it, and then slit and process the ultra-thin glass substrate For each small unit, and finally each unit is peeled off from the platform. [0005] During the peeling process, the ultra-th...
