Touch screen and manufacturing method thereof

Abstract

The invention provides a touch screen and a manufacturing method thereof. A touch screen, defining a central bonding area and a peripheral area surrounding the central bonding area, the touch screen includes a touch module and a display module, the touch module and the display module The groups are bonded to each other in the central bonding area, and there is a gap between the touch module and the display module in the peripheral area, and the gap is filled with a colloid layer. A method for manufacturing a touch screen, comprising the steps of: bonding a touch module and a display module to each other through an adhesive layer in the central bonding area of ​​the touch screen; and filling a colloid layer in the peripheral area of ​​the touch screen There is a gap between the touch module and the display module, wherein the peripheral area surrounds the central bonding area. The colloidal layer ensures that the display module will not be deformed by pressing when the edge of the touch module is pressed, and eliminates water ripples on the edge.

Description

technical field [0001] The invention relates to a touch technology, in particular to a touch screen and a manufacturing method thereof. Background technique [0002] In recent years, touch panels have been widely used. A touch screen using a touch panel is also called a touch screen, which is an inductive display device capable of receiving touch operations to generate input signals. [0003] A general touch screen includes a touch module and a display module. There are many ways to integrate the touch module and the display module, such as snapping and fixing with auxiliary devices, and glue bonding. Among them, there is a bonding method called full bonding in the method of glue bonding, that is, laying an entire surface of optical glue on one surface of the touch module or display module, and then bonding the two. In this method, since the surface of the display module for bonding is not completely flat, that is, the peripheral area with a frame is higher than the middle ...

AI Technical Summary

Problems solved by technology

Since the colloid has a certain thickness, in a display module without a frame, the thickness of the colloid itself will cause a gap between the display module and the touch module in the peripheral area; in a display module with a frame, the thickness of the colloid The thickness is greater than the height of the frame, so there will be a gap between the display module and the touch module in the peripheral area. During the user's use, if the user presses the peripheral area, the display module will be deformed due to pressure, thereby Phenomena such as water streaks are generated, which seriously affect the display effect of the display module
