Description
Technical field
The utility model relates to technical field of liquid crystal display, specifically be a kind of anti-watermark foam glue frame mould group.
Background technique
With the continuous development of society, field of liquid crystal display is developed rapidly, and capacitive touch screen production process relates to
And to attaching process crucial together, it is divided into full fitting and frame patch, and cover board (transparent glass) and liquid crystal display are bonded process
In be typically used for is frame patch technique, laminated material is generally foam rubber, and foam rubber is usually and is punched in the prior art
A frame shape it is whole, cover board is connect with liquid crystal display by foam glue frame, the ground that cover board does not have foam glue frame to connect with liquid crystal display
Side is disconnected from each other, therefore a cavity is enclosed between cover board, foam glue frame and liquid crystal display, when carrying out touch-control by cover clamp
When liquid crystal display, under the effect of external force, the air in cavity is discharged and is temporarily forming vacuum state, and cover board generates deformation and and liquid
Crystalline substance screen fitting, when external force disappears, cover board keeps fit-state with liquid crystal display under the action of vacuum, slowly enters sky to air
After intracavitary, cover board is slowly separated with liquid crystal display, this process cover plate and liquid crystal display (surface is smooth) will appear incomplete contact between；When
When the object incomplete contact between of two glossy clears, contact place and discontiguous place will cause human eye see two kinds it is different
Visual effect, the region of full contact is known as watermark, therefore during cover board is slowly separated with liquid crystal display, meeting on screen
Watermark is generated, and these watermarks can seriously affect the usage experience of user.
Utility model content
