Device and method for fully bonding touch screen with display screen

Abstract

The invention discloses a device and a method for fully bonding a touch screen with a display screen. The device and the method can improve a display effect of the display screen effectively, reduce the thickness of a product, and eliminate dust and moisture pollution. The method comprises the steps that the display screen is placed in a lower cavity jig; a bonding face of the display screen faces upward; the display screen, the lower cavity jig and a lower part of a lower cavity form a lower part cavity body; the touch screen is placed in the lower cavity jig; a bonding face of the touch screen faces downward; an upper cavity is moved over the lower cavity; the upper cavity is moved downwards to the lower part of the upper cavity to form a middle cavity body with the upper part of the lower cavity; the lower part cavity body is vacuumized; the middle cavity body and an upper part cavity body at the upper part of the upper cavity are vacuumized simultaneously; when vacuum values in the middle cavity body and the upper part cavity body reach rated vacuum values, vacuum relief is conducted on the upper part cavity body; and compressed air is led in.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch screens, and in particular to a method and device for fully laminating a touch screen and a display screen. Background technique [0002] The touch screen is a set of transparent absolute positioning system, which is composed of touch detection parts and touch screen controller; The point coordinates are sent to the central processing unit, and at the same time, the commands sent by the central processing unit can be received and executed to realize human-computer interaction. At present, touch screens have been widely used in fields such as public information inquiry, industrial control, military command, electronic games, and multimedia teaching. [0003] At present, the traditional bonding process of touch screen and display screen simply uses double-sided adhesive tape to fix the touch module and the four sides of the display panel. This is also the bonding method adopted ...

Problems solved by technology

[0004] However, due to the air layer between the panel and the touch module, the display effect will be greatly reduced after the light is refracted, and because the surface is highly reflective, the reflected light affects the contrast, and the loss of light transmission is large, resulting in low brightness. The layer is easily polluted by dust and water vapor in the environment, which affects the use of the machine
