Composite Panel Fastening Structure for Ultra-Thin Displays

The patent applies composite materials by constructing the composite panel with multiple layers including front and rear skins made of different materials (e.g., metal and polymer) combined with a core layer. This composite structure provides both the thinness required for ultra-thin displays and the structural rigidity needed to support large screens, resolving the contradiction between reduced thickness and maintained strength.

The patent applies segmentation by dividing the composite panel into distinct layers (front skin, rear skin, core) with each layer having specific functions. The fastening hole is strategically positioned to pass through all layers, allowing the fastening member to anchor securely across the entire composite structure. This segmented approach maintains manufacturing simplicity while ensuring durable coupling through multi-layer engagement.

The patent applies local quality by providing different structural characteristics at different locations of the composite panel. The fastening member features a head with specific geometric properties (e.g., inclined surfaces, engagement portions) localized at the insertion point, while the rest of the panel maintains uniform thinness. This localized structural enhancement improves frame flatness and stability without requiring complex coupling structures throughout the entire device.
