AI Technical Summary
Technical Problem
Existing liquid crystal display panel sealants face a trade-off between adhesive strength and moisture resistance, with the addition of inorganic fillers like alumina compromising flexibility and adhesion.
Method used
A liquid crystal sealant comprising a curing compound, a thermosetting agent, a photopolymerization initiator, and aluminum oxide with an α-oxidation rate of less than 80%, along with specific particle size and aspect ratio, to enhance both moisture resistance and adhesion strength.
Benefits of technology
The sealant achieves high moisture resistance and adhesion strength to the substrate, balancing flexibility and adhesion without compromising the integrity of the sealing member.
