Protection Panel Cutout Segmentation for Bubble-Free Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing occupancy of displays in electronic devices due to miniaturization of driving components and the need for a structure that can be curved from a flat state poses challenges in protection and adhesion, particularly in preventing bubble formation during attachment of protection panels to display panels.
Innovation Solution
A protection panel comprising a first panel member with a cutout portion and a bridge portion, along with a second panel member with a higher adhesive force, is used in conjunction with a cover member, film member, and adhesive layers to ensure uniform coupling and prevent bubble formation, enhancing the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a protection panel is attached to a display panel with high adhesive force, then strong adhesion is achieved, but bubble formation occurs during attachment
Solution Approach 1:
The protection panel is divided into multiple regions through cutout portions that extend from edges toward the center. These cutout portions create separate attachment zones that can be bonded independently, allowing air to be expelled during the attachment process and preventing bubble formation while maintaining strong overall adhesion.
Solution Approach 2:
Different regions of the protection panel have different structures - edges have cutout portions for bubble prevention while the center maintains full adhesive coverage for strong bonding. This local differentiation allows each region to fulfill its specific function optimally.
2Reliability
If the protection panel structure is made complex with cutout portions and bridge portions, then bubble formation is prevented, but manufacturing complexity increases
Solution Approach 1:
The panel is segmented into cutout portions and bridge portions, where bridge portions connect adjacent cutout portions. This segmentation approach systematically prevents bubbles while maintaining a structured, manufacturable design pattern that can be replicated.
Solution Approach 2:
The bridge portions serve multiple functions: they maintain structural integrity of the protection panel, provide pathways for adhesive application, and allow controlled expansion/contraction during attachment. This multi-functionality reduces the need for additional components.
3Area of stationary object
If display occupancy is increased due to miniaturization, then device size is reduced, but protection and adhesion challenges increase
Solution Approach 1:
By segmenting the protection panel into cutout portions, the adhesive bonding is distributed across multiple separate zones rather than one large continuous zone. This distribution maintains reliable adhesion even as the overall display area becomes smaller and more constrained.
Solution Approach 2:
The protection panel uses a thin film structure with cutout portions that can conform to the display panel surface during attachment. This flexibility ensures reliable adhesion in miniaturized devices where rigid protection panels would be difficult to attach without bubbles.

AI summary
A protection panel includes a first panel member, a film member, and a cover member. The first panel member includes a first panel member body portion, and a first adhesive portion on the first panel member body portion, the film member is on the first panel member, and the cover member is on the first adhesive portion. A portion of at least one selected from the first panel member body portion and the first adhesive portion of the first panel member includes a cutout portion which separates adjacent portions thereto from each other.
