Flexible Supporting Board for Bubble-Free Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laminating methods for flexible screens and curved cover plates often result in bubbles due to uneven pressure distribution, leading to poor adhesion and low yield in full-screen applications.
Innovation Solution
A laminating device with an elastic support assembly and flexible supporting board that deforms from a ridge shape to a flattened state under pressure, allowing for gradual pressure distribution from the center to the sides, effectively eliminating bubbles and improving adhesion between the flexible screen and the curved cover plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a silicone pad is used to press the flexible screen to the inner side of the curved cover plate, then the flexible screen can be laminated to the cover plate, but bubbles are prone to appear in the bending area due to insufficient laminating pressure
Solution Approach 1:
The support board is designed to be deformable, transitioning from a first state with a ridge shape to a second state that is substantially planar under pressing force. This dynamic deformation allows the support board to adapt to the curved cover plate's geometry, ensuring uniform pressure distribution across the bending area and eliminating bubbles during lamination.
Solution Approach 2:
The support board's physical state is changed from rigid to deformable, allowing it to change shape in response to applied pressure. This parameter change enables the board to conform to the curved surface, maintaining consistent contact and pressure throughout the lamination process, thereby preventing bubble formation.
2Ease of operation
If uniform pressure is applied during lamination, then the process is simple, but the bending area receives insufficient pressure leading to poor adhesion
Solution Approach 1:
The support board dynamically changes its shape from a ridge configuration to a planar configuration under applied pressure. This dynamic adaptation allows the system to maintain operational simplicity while automatically achieving uniform pressure distribution across the bending area, resolving the contradiction between ease of operation and manufacturing precision.
3Stability of the object's composition
If the support board is rigid, then it provides stable support, but it cannot adapt to the curved surface leading to uneven pressure distribution
Solution Approach 1:
The support board transitions from a rigid structure to a deformable one that can dynamically adjust its shape. In the first state, it provides stable ridge support; under pressure, it deforms to conform to the curved surface, ensuring both stability and adaptability throughout the lamination process.
Solution Approach 2:
The physical state of the support board is changed from rigid to deformable, allowing it to alter its shape parameter in response to applied force. This enables the board to maintain stability in its initial state while adapting to the curved surface during lamination, resolving the contradiction between stability and adaptability.

Function Achieved in This Case
The solution effectively reduces bubble formation and enhances the yield of the laminating process by ensuring consistent contact between the flexible screen and the curved cover plate, improving the overall quality of the lamination.
Implementation Method 1
The elastic support assembly is arranged to be deformable in the pressing direction of the curved cover plate so that the flexible supporting board is deformed from a first state to a second state under the pressing effect of the curved cover plate

AI summary
A laminating device adapted for laminating a curved cover plate and a flexible screen. The laminating device includes at least one elastic support assembly and a flexible supporting board for supporting the flexible screen. The flexible supporting board includes a top wall having a central spine portion and loading portions; The elastic support assembly is deformable so that the flexible supporting board can be deformed from a first state to a second state under a pressing effect of the curved cover plate; in the first state, the flexible supporting board is in a shape of a ridge and one of the loading portions is obliquely connected between the central spine portion and one of the side walls, so that in the process of the flexible supporting board being deformed from the first state to the second state, the inclination of the loading portion gradually decreases.
