Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum laminating technologies are inadequate for lamination of glass cover plates with large radii and flexible OLED panels, leading to incomplete lamination, defects such as bubbles and cracks, and inability to effectively profile the flexible panel for large-radian applications.
Innovation Solution
A curved-surface laminating device featuring a flexible profiling jig with a shape-matched laminating surface, a bearing film attached to the flexible panel, and tensioning devices that profile the panel to match the curved-surface cover plate, allowing for effective lamination of both flat and bent areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vacuum laminating technology is used, then lamination of glass cover plate with small radian (30°-40°) and display panel can be achieved, but it cannot meet lamination requirements for glass cover plate with large radian and display panel
Solution Approach 1:
The patent employs a flexible profiling jig that can dynamically adjust its curvature to match different radian requirements (30°-40° small radian and larger radian configurations). The jig's flexibility allows it to adapt its shape during the lamination process, enabling precise profiling of the flexible panel regardless of the target radian, thereby resolving the contradiction between adaptability and manufacturing precision.
Solution Approach 2:
The invention changes the key parameter of the profiling jig from fixed curvature to variable curvature. By adjusting the radian of the profiling jig to match different glass cover plate curvatures, the system can achieve complete lamination across various radian ranges without compromising on lamination quality or producing defects.
2Ease of manufacture
If existing vacuum laminating technology is used for large radian applications, then the process is simple, but lamination is incomplete and defects such as bubbles and cracks occur
Solution Approach 1:
The patent implements preliminary profiling of the flexible panel using the flexible profiling jig before the actual vacuum lamination process. This preliminary action ensures that the flexible panel is pre-shaped to match the glass cover plate curvature, preventing incomplete lamination and defects during the subsequent vacuum lamination step, thereby maintaining reliability without significantly complicating the overall process.
3Device complexity
If the flexible panel is not profiled before lamination, then the manufacturing process is simpler, but bubbles and cracks occur during lamination
Solution Approach 1:
The flexible profiling jig acts as an intermediary tool between the flexible panel and the glass cover plate. It temporarily assumes the role of shaping the flexible panel to the correct curvature before lamination, eliminating the need for complex in-situ profiling mechanisms during lamination itself. This intermediary approach prevents bubbles and cracks while keeping the overall device complexity manageable.
