Problems solved by technology
However, the use of frame glue also brings new interface problems: because of the difference in composition and refractive index between the frame glue and the surface glue, there is a clear boundary between the two after lamination, which affects the display effect of the component; and long-term use After that, the traces of the interface will become more and more obvious, resulting in a very large negative visual effect
However, the combination of this frame glue with silicone LOCA cannot avoid the bonding boundary, and the frame glue is heat-cured, which greatly reduces production efficiency when it is matched with UV-cured surface glue

Abstract
The invention provides a borderless full-fit frame glue, a borderless full-fit surface glue and a display panel. The borderless full-fit frame glue includes: 30-55% of modified (meth)acrylate oligomers, 30-60% of plasticizers, 5-20% of (meth)acrylate monomers, poly Functional chain transfer agent 0.1‑5%, photoinitiator 0.1‑8% and viscosity modifier 0.5‑5%; unbounded full-fit surface adhesive includes: modified (meth)acrylate oligomer 30‑55%, Plasticizer 30‑60%, (meth)acrylate monomer 5‑20%, multifunctional chain transfer agent 0.1‑5% and photoinitiator 0.1‑8%; multifunctional chain transfer agent includes difunctional ester-free thiols and thiols with a functionality of 3 or more. The borderless full-fit frame glue and the borderless full-fit surface glue provided by the present invention are used to bond the display panel, which can eliminate the interface between the frame glue and the surface glue, and achieve the effect of seamless bonding.
Description
A borderless full-fit frame glue, a borderless full-fit surface glue and a display panel technical field The invention belongs to the technical field of liquid optical glue, be specifically related to a kind of unbounded line full-fit sealant, unbounded line full-stick Adhesive and display panel. Background technique [0002] Full lamination refers to the use of liquid optical glue to seamlessly attach the display module and the touch panel or cover to achieve Reduce light loss and glare, increase contrast, improve display effects, and have many effects such as dust and water resistance and stress buffering Technology. [0003] The liquid optical adhesive for full lamination includes a frame glue and a surface glue. The surface glue is used to bond the display module and the touch surface The optical glue of the board or cover is coated on the display surface of the display module according to a certain pattern. Production of liquid crystals in existing industries ...
