Problems solved by technology

The whole set of gluing equipment is expensive, and liquid UV glue is used, because it is one-way extrusion flow, it is easy to produce thickness difference during the defoaming process, often there will be bubbles left, and the screen will appear dull phenomenon (similar to Moore pattern), and it is easy

Embodiment 1

[0018] Embodiment 1: A manufacturing process of a fully sealed touch liquid crystal integrated screen, which uses solid ultraviolet flexible glue to bond sequentially arranged components to each other to form a whole. The components include a touch screen group, a liquid crystal screen group, a plexiglass frame and Glass cover, the backlight module is embedded between the LCD screen group, the plexiglass frame and the glass cover; the process includes: 1) Attach a solid-state film with a thickness of 50 to 100 μm between any two adjacent components Ultraviolet flexible glue, the backlight module is directly embedded between the LCD screen group, the plexiglass frame and the glass cover; 2) Degassing: put the components attached with the solid ultraviolet flexible glue into the autoclave for 10~ 50min, control the pressure in the autoclave to 0.5kg~3kg, and the temperature to 30~40℃; 3) Curing: use a high-power UV lamp to irradiate the transparent glued body with strong light, l...

Embodiment 2-3

[0020] Embodiment 2-3: using the same preparation method as in Example 1, the difference is that the thickness, pressure and temperature in the pre-lamination and degassing steps listed in Table 1 are used to replace the corresponding values ​​​​used in Example 1, Get fully sealed touch LCD integrated screens of different sizes.

[0021] Table 1:

[0022]

[0023] In the embodiment, if the thickness of the solid ultraviolet flexible adhesive is less than 50 μm, the fluidity is not enough, and thickness difference is likely to occur. If the thickness is higher than 300 μm, the fluidity is too full and overflowing glue is likely to occur. If the temperature and pressure are lower than the limit value, the solid ultraviolet flexible adhesive will not be easily bonded to each component; during the defoaming process, the temperature is 30-65°C, the pressure is 0.5-10kg, and the defoaming time is 10-250 minutes. If the value is higher than the limit value, the The resin is easy ...

Abstract

The invention discloses a manufacturing technology of a full-sealed touch liquid crystal integrated screen. A solid ultraviolet flexible adhesive is adopted for attaching sequentially-arranged components to form a whole. The components include a touch screen set, a liquid crystal screen set, an organic glass frame and a glass cover plate. Backlight modules are embedded among the liquid crystal screen set, the organic glass frame and the glass cover plate. According to a transparent adhesive body produced by adopting the novel technology, no bubbles are likely to be generated, the distances between two adjacent adhesive bodies can be equal, no thickness concave-convex difference exists, no numbing phenomenon exists, and the novel adhesive touch display backlight integrated screen is not likely to squeeze out adhesives.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a fully sealed and anti-interference touch liquid crystal integrated screen and a manufacturing process thereof. Background technique [0002] Usually, the lamination of large-size transparent glass is to apply liquid UV ultraviolet photoresist on one glass surface, so that the photoresist flows and distributes evenly on the glass surface, and then another piece of uncoated transparent glass is glued from the head of the glued glass. Close to, use a roller on the surface of the uncoated glass to squeeze the gas and air bubbles in the liquid glue out of the bonded body, and finally use a high-power UV ultraviolet lamp on the top of the transparent bonded body to cure and bond. The whole set of gluing equipment is expensive, and liquid UV glue is used, because it is one-way extrusion flow, it is easy to produce thickness difference during the defoaming process, often there wi...
