Stretchable Display Panels With Elastic Fillers for Packaging Reliability

The patent applies local quality by introducing an elastic filling layer specifically within the perforated regions where weakness occurs, while maintaining the original perforated structure for flexibility. The elastic filling layer is placed locally at the inner side walls of perforated structures to provide reinforcement exactly where needed, without affecting the overall flexible nature of the display panel.

The patent uses composite materials by combining the rigid base structure with an elastic filling layer made of organic materials. This composite construction allows the display panel to maintain both the flexibility provided by the perforated structure and the packaging reliability provided by the elastic filling layer, resolving the contradiction between adaptability and reliability.

The patent applies beforehand cushioning by placing the elastic filling layer in advance within the perforated regions before the display panel undergoes stretching or bending. This pre-positioned elastic layer acts as a cushion that prevents rupture of the packaging layer during subsequent mechanical deformation, maintaining integrity while allowing stretchability.

The elastic filling layer serves as an intermediary between the rigid base structure and the packaging layer. It mediates the mechanical stresses during stretching and bending, absorbing and distributing forces to prevent direct transmission that would cause packaging layer rupture, thus maintaining integrity while preserving stretchability.

The patent applies local quality by reinforcing only the critical areas (inner side walls of perforated structures) with elastic filling layer, while keeping the packaging layer thin in other areas to maintain flexibility. This localized reinforcement provides anti-rupture capability exactly where stress concentrates, without adding unnecessary thickness that would reduce flexibility.

The elastic filling layer acts as an intermediary protective element between the thin packaging layer and the mechanical stresses it encounters. It provides the necessary support to prevent rupture of the thin packaging layer while allowing it to remain thin for flexibility, effectively decoupling the thickness from the strength requirement.
