Curved Display Bonding Surface for Delamination Control

The patent applies a hyperbolic cosine curve to the bearing surface of the structural component, creating a specific curved geometry that matches the natural deformation of the sheet. This curvature is designed to distribute adhesion forces uniformly across the bonding surface, preventing delamination while maintaining the immersive curved display effect. The curve is defined by y(x) = a·cosh(x/b) + c, where the parameters are optimized to match the sheet's elastic deformation characteristics.

The patent applies local quality by creating a non-uniform bearing surface geometry that specifically addresses the stress distribution pattern. The hyperbolic cosine curve provides different local curvatures along the bonding surface, with tighter curvature in regions where the sheet experiences higher stress and gentler curvature where stress is lower. This localized geometric variation ensures uniform adhesion forces throughout the entire bonding area.

The patent changes the geometric parameters of the bearing surface from a simple cylindrical shape to a hyperbolic cosine curve. This parameter change in the bearing surface geometry allows for optimized stress distribution that compensates for the reduced bonding surface area inherent in thin sheets. The curve parameters (a, b, c in y(x) = a·cosh(x/b) + c) are specifically selected to match the mechanical properties and thickness of the sheet, ensuring reliable bonding even with minimal material.
