Solution Overview
Problem
The existing methods for manufacturing curved OLED hard display panels result in increased overall thickness, making it difficult to achieve a desired bending curvature, which limits their application.
Innovation Solution
An attachment apparatus and method that allows for the direct attachment of a flexible display layer onto a pre-bent cover glass by adjusting the curvature radius, using a holding component, a supporting component with movable parts, and a servo motor to control the attachment process, ensuring the flexible display layer matches the desired curvature of the cover glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If planar bonding is used to attach the flexible display layer to the cover glass, then the bonding strength is improved, but the overall thickness increases making it difficult to achieve desired bending curvature
Solution Approach 1:
The cover glass is pre-bent to the desired curvature before bonding with the flexible display layer. This preliminary shaping allows the final bonded structure to maintain the target curvature without requiring excessive thickness for structural integrity, thus achieving both strong bonding and desired bending curvature.
Solution Approach 2:
The patent employs a dynamic bonding process where the supporting component can adjust its curvature to match the cover glass during bonding. This dynamic adaptation ensures optimal contact and bonding strength across the entire surface while maintaining the thin profile needed for flexibility.
2Stability of the object's composition
If the overall thickness is increased to improve structural stability, then the stability is improved, but the bending stress increases making it difficult to achieve desired curvature
Solution Approach 1:
The cover glass is pre-formed to the exact desired curvature before assembly. This preliminary action ensures that the final structure achieves the target shape without requiring increased thickness for stability, as the curvature is built-in rather than forced after assembly.
Solution Approach 2:
The patent changes the physical state and geometric parameters of the cover glass by pre-bending it to the target curvature. This parameter change allows the structure to achieve both stability and flexibility, as the pre-formed curvature distributes stresses more effectively than a flat structure forced into curvature after assembly.
3Ease of manufacture
If direct planar bonding is used, then the manufacturing process is simplified, but the ability to achieve pre-determined bending curvature is reduced
Solution Approach 1:
The cover glass is pre-bent to the desired curvature before bonding, which maintains manufacturing simplicity while achieving precise curvature control. This preliminary shaping of the cover glass allows the flexible display layer to conform to the exact desired shape without complex post-bonding forming operations.
Solution Approach 2:
The supporting component acts as an intermediary tool that temporarily provides the target curvature during bonding. This mediator enables precise curvature control during the bonding process while keeping the overall manufacturing process relatively simple, as the supporting component can be removed after bonding completes.
