Curable Silicone Composition for Optical Displays

The patent changes the chemical parameters of the catalyst system by selecting specific platinum complexes with ligands (such as phosphine ligands or N-heterocyclic carbene ligands) that enable fast curing at room temperature without causing discoloration. This parameter change in catalyst structure and composition allows achieving high curing rate while maintaining the transparency required for optical display applications.

The patent modifies the catalyst system parameters to achieve room temperature curing with fast curing rate. By using specific platinum-based catalysts with appropriate ligands, the reaction activation energy is reduced, enabling the curing reaction to proceed rapidly at low temperatures without requiring external heating or UV irradiation.

The patent replaces the UV irradiation mechanism with a chemical catalyst mechanism. Instead of using external energy input (UV light) to drive the curing reaction, the system uses a platinum-based catalyst that enables the hydrosilylation reaction to proceed spontaneously at room temperature, allowing complete curing throughout the adhesive layer including decorative portions that block UV transmission.
