Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a fully laminated liquid crystal display screen capable of controlling glue overflow. Background Art

When there is a lot of optical glue, it will cause the optical glue to overflow in many places, and the overflow amount is large. In addition, some areas may not be filled with enough optical glue, resulting in a waste of optical glue and increasing the difficulty of manual wiping. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to control the overflow of optical glue during full bonding, so that the overflow of optical glue is controlled within a smaller range or the glue does not overflow, thereby reducing the waste of optical glue and reducing the difficulty of manual wiping.
