Problems solved by technology
However, this bonding method has the following defects: 1. It must be carried out in a vacuum environment, otherwise air will enter the bonding layer, and the air bubbles cannot be removed
2. The thickness of the ink on the cover glass must be strictly controlled, otherwise the solid optical glue cannot fill the steps between the ink and the glass, resulting in bubbles that cannot be removed
3. Once the cover glass, solid optical glue, and functional glass are bonded and defoamed, it will be difficult to disassemble and rework, and the material reuse rate is very low.
4. The production of solid optical glue has high requirements for a dust-free environment, and the cost of materials is relatively high

Embodiment Construction
[0014] The present invention will be further described below in conjunction with drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.
[0015] Please refer to figure 2 as shown, figure 2 It is a schematic structural diagram of a capacitive screen bonded with glue provided by an embodiment of the present invention.
[0016] In this embodiment, the capacitive screen bonded by glue includes a cover glass 201 , a double-sided glue 201 with a hole and a functional glass 203 . The slit-shaped double-sided adhesive tape 202 is pasted on the non-visible window area where the cover glass 201 and the functional glass 203 overlap.
[0017] Such as image 3 as shown, image 3 It is a flow ch...

The invention discloses a capacitive screen glued by using opening glue and a manufacturing process thereof. The capacitive screen comprises end cover glass, an opening-type double faced adhesive tape and functional sheet glass, wherein the opening-type double faced adhesive tape is stuck in a non-visual window region overlapped by the end cover glass and the functional sheet glass. According to the capacitive screen, the common opening-type double faced adhesive tape is used for replacing existing solid-state optical glue, a vacuum gluing manner does not need to be adopted, high-pressure de-foaming does not need to be carried out, the cost of materials is reduced and the gluing yield is improved; the capacitive screen is easy to detach and the utilization rate of reworking and detaching is improved.
Description
technical field [0001] The invention relates to the technical field of capacitive screen bonding, in particular to a capacitive screen bonded with glue and a manufacturing process thereof. Background technique [0002] In the touch screen industry, G+G (glass cover plate + glass functional sheet) capacitive screen product lamination process basically has two methods: solid optical adhesive (OCA) and liquid optical adhesive (LOCA). The main principle of these two processes is to use solid optical glue or liquid optical glue to paste the cover tempered glass and the sensor function sheet together. The yield rate is not high, and the ink thickness requirements for the cover glass are very high, and it is difficult to disassemble and rework after being made into a finished touch screen. The traditional solid-state optical glue bonding process is to paste a layer of solid-state optical glue on the cover glass or functional glass first, and then use the bonding equipment to carry...
