Photocurable Resin Lamination for Display Lifting Suppression

The patent changes the chemical composition parameters of the photocurable resin by incorporating specific ring structures (cyclic carbonates, cyclic carboxylic acids, or cyclic anhydrides) in controlled amounts (0.1-10 wt%). This compositional parameter change modifies the curing characteristics to achieve uniform curing throughout the resin layer while maintaining low elasticity, thereby preventing the lifting phenomenon without requiring high bonding pressure.

The patent creates a composite photocurable resin system by combining multiple components: the base photocurable resin, the ring structure compounds (0.1-10 wt%), and optionally other additives. This composite formulation synergistically achieves both low elasticity for reduced bonding pressure and uniform curing to prevent lifting, resolving the contradiction between these two requirements.

The patent modifies the chemical composition by adding ring structure compounds (cyclic carbonates, cyclic carboxylic acids, or cyclic anhydrides) in specific amounts (0.1-10 wt%). This compositional change alters the curing kinetics and network structure of the photocurable resin, enabling complete and uniform curing that prevents uncured components from permeating into cured regions, thereby eliminating swelling and wrinkles while maintaining adhesive strength.

The ring structure compounds act as intermediary substances that mediate the curing process. They facilitate uniform crosslinking throughout the resin layer, preventing the formation of uncured regions that would otherwise allow component permeation and subsequent swelling. This intermediary role resolves the contradiction between achieving sufficient adhesive strength and maintaining compositional stability.
