Curved Touch-Screen Panel Manufacturing via Intersecting Region Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of touch-screen panels with bent shapes often results in unwanted folds and cracks due to the bending process, which affects their durability and performance.
Innovation Solution
A method of manufacturing a curved touch-screen panel involves determining intersecting regions where axes intersect and removing these areas before bending the panel, allowing it to be shaped without unwanted folds or cracks, and maintaining consistent or varying transparent electrode patterns across different regions to ensure effective touch input sensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flat touch-screen panel is bent to create a curved shape, then the panel achieves a desired curved form factor, but unwanted folds and cracks occur during the bending process
Solution Approach 1:
The patent applies preliminary action by pre-defining and removing intersecting regions from the flat touch-screen panel before the bending process. These regions are identified based on the target curved shape's geometric parameters, and their removal in advance prevents the formation of folds and cracks that would otherwise occur during bending, thereby ensuring panel integrity while achieving the desired curved form factor.
2Reliability
If intersecting regions are removed from the touch-screen panel before bending, then unwanted folds and cracks are minimized, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the touch-screen panel into distinct regions: intersecting regions to be removed and non-intersecting regions to be retained. This segmentation is based on geometric parameters of the target curved shape, allowing precise identification and removal of only the necessary intersecting regions while preserving the functional areas, thus minimizing manufacturing complexity while ensuring panel integrity.
3Ease of manufacture
If the transparent electrode pattern is maintained consistently across all regions, then touch input sensing is simplified, but the bending process may cause misalignment or distortion
Solution Approach 1:
The patent applies local quality by differentiating the treatment of transparent electrode patterns in intersecting regions versus non-intersecting regions. In intersecting regions that are removed, the electrode patterns are correspondingly removed. In retained non-intersecting regions, the patterns are preserved with their original geometric parameters. This localized approach ensures that electrode patterns in the final curved panel remain properly aligned and undistorted, maintaining manufacturing precision while simplifying the overall manufacturing process.

AI summary
A touch-screen panel may include a first touch-screen portion, a second touch-screen portion, and a third touch-screen portion. The first portion may include a first transparent electrode set. The second portion may include a second transparent electrode set, may abut the first portion at a first boundary, and may be oriented at a first angle with respect to the first portion. The third portion may include a third transparent electrode set, may abut the first portion at a second boundary, and may be oriented at a second angle with respect to the first portion. A length of the second portion in a direction parallel to the first boundary may be less than a sum of a length of the first portion in the direction parallel to the first boundary and a width of the third portion in a direction perpendicular to second boundary.
