Abstract
The invention provides a silicone liquid optical adhesive and a method for using the same, including frame glue and surface glue; wherein, according to the standard GB / T 614‑2006 general method for measuring the refractive index of chemical reagents for testing, the frame glue and surface glue The refractive index difference is ≤0.005. The refractive index difference between the frame glue and the surface glue in the organic silicon liquid optical glue provided by the invention is extremely small, and the chemical compatibility is strong, which can ensure that there is no trace at the interface between the frame glue and the surface glue after lamination; and, the present invention Frame glue and surface glue have excellent anti-aging and anti-yellowing properties.
Description
technical field [0001] The invention belongs to the technical field of adhesives, and relates to a liquid organic silicon optical adhesive and a use method thereof. Background technique [0002] Full lamination refers to the use of liquid optical glue to seamlessly bond the display module with the touch panel / cover to reduce light loss and glare, increase contrast, and improve display effects. It is also dustproof, waterproof, and stress buffering. technology with many effects. At present, the full-fit liquid optical adhesives on the market all adopt the form of "frame glue + surface glue", and the joint use of frame glue and surface glue has brought new interface problems. Due to the poor compatibility between the frame glue and the surface glue, the interface is obvious, which affects the display effect of the lamination; at the same time, due to the difference in refractive index between the frame glue and the surface glue, the cured screen is in the gap between the fram...
