Optical Film Alignment for Non-Linear Display Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing display units fail to effectively align panels with non-linear layouts and optical films, as they rely on rectangular alignment techniques that are not suitable for layouts including non-linear lines.
Innovation Solution
A method involving the formation of alignment marks on the optical film and panel, followed by cutting a cut-out line corresponding to a predetermined closed curve layout on the optical film, allowing for precise alignment and lamination of the optical film onto the panel, even when both have non-linear layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rectangular alignment techniques are used to align panels and optical films, then the alignment process is simple and straightforward, but it cannot properly align panels and optical films with non-linear layouts
Solution Approach 1:
The patent divides the alignment process into two independent stages: first forming alignment marks on the optical film, then using those marks to guide the cutting process. This segmentation allows the alignment marks to be created independently of the final cut shape, enabling the system to handle non-linear layouts while maintaining simple alignment operations.
Solution Approach 2:
The patent applies preliminary action by forming alignment marks on the optical film before performing the cutting process. These pre-formed alignment marks serve as reference points that guide the subsequent cutting operation, allowing the system to accommodate non-linear layouts while maintaining precise alignment through a simplified two-step process.
2Manufacturing precision
If alignment marks are formed on the optical film before cutting, then precise alignment can be achieved for non-linear layouts, but the process complexity increases
Solution Approach 1:
The patent segments the manufacturing process into distinct steps: first forming alignment marks, then using those marks to guide cutting. This segmentation isolates the precision requirement to a specific step (mark formation) while the cutting step can use simpler guidance based on those pre-formed marks, thereby achieving high precision without proportionally increasing overall process complexity.
Solution Approach 2:
The alignment marks serve as an intermediary element between the optical film and the cutting process. By introducing these intermediate reference points, the system achieves precise alignment for non-linear layouts without requiring complex real-time alignment systems during cutting, thus managing process complexity while improving precision.
3Manufacturing precision
If the optical film is cut into a closed curve layout corresponding to the panel shape, then the display unit layout can be accurately formed, but the cutting process becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-forming alignment marks on the optical film before cutting. These pre-formed marks serve as reference points that guide the cutting process, enabling accurate formation of closed curve layouts corresponding to non-linear panel shapes while simplifying the cutting operation through predetermined reference guidance rather than requiring complex real-time positioning systems.

AI summary
A method of manufacturing a display unit including: preparing an optical film; forming a first alignment mark on the optical film; forming a cut-out line, corresponding to a predetermined closed curve layout, on the optical film based on a position of the first alignment mark; preparing a panel having a second alignment mark; aligning the optical film and the panel based on the positions of the first alignment mark and the second alignment mark; and laminating the optical film, after the processing of forming the cut-out line, on the panel.
