Segmented Digitizer Support Layout for Foldable Display Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices face challenges in seamlessly integrating a digitizer that can be easily folded or bent without overlapping the folding areas, which affects user convenience and structural integrity.
Innovation Solution
A display device design featuring multiple support plates and digitizers arranged in a specific configuration, allowing the digitizer to extend and overlap only in non-folding areas, enabling easy folding or bending without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the digitizer is disposed below the non-folding areas of the display module, then the folding area is not blocked and the display device can be easily folded, but the digitizer area is reduced and cannot cover the entire display area
Solution Approach 1:
The display module is divided into a folding area and non-folding areas, and the digitizer is correspondingly divided into multiple portions. The first digitizer is disposed below the first non-folding area, the second digitizer is disposed below the second non-folding area, and these digitizer portions are connected through a folding part that can be folded along with the folding area. This segmentation allows each digitizer portion to be positioned in non-folding areas while maintaining complete digitizer coverage through the connected folding part.
Solution Approach 2:
The digitizer structure extends into the third dimension by including a folding part that can be folded along with the folding area of the display module. This allows the digitizer to maintain its functional area across the entire display surface while accommodating the folding motion, effectively solving the contradiction between maintaining full digitizer coverage and enabling easy folding.
2Area of stationary object
If the digitizer overlaps the folding area, then the digitizer area is maximized to cover the entire display area, but the folding operation becomes difficult and structural integrity is compromised
Solution Approach 1:
The digitizer is segmented into multiple portions corresponding to different areas of the display module. The folding part is specifically designed to be disposed at the folding area and can be folded along with the display module, while other digitizer portions are disposed below non-folding areas. This segmentation prevents the main digitizer body from blocking the folding area while maintaining complete digitizer coverage.
Solution Approach 2:
The folding part acts as an intermediary element between the digitizer and the folding area of the display module. It is specifically designed to accommodate the folding motion, allowing the digitizer to maintain its area across the entire display surface while enabling smooth folding operations without structural compromise.
3Area of stationary object
If a single digitizer is used to cover the entire display area, then complete input functionality is achieved, but the structure becomes complex and difficult to fold
Solution Approach 1:
The digitizer is divided into multiple portions (first digitizer, second digitizer, and folding part) that are disposed at different locations and have different functions. This segmentation simplifies the overall structure by allowing each portion to be optimized for its specific location, while still achieving complete digitizer coverage when all portions are combined.
Solution Approach 2:
Different portions of the digitizer are disposed at different locations with different structural characteristics. The folding part is specifically designed for the folding area with foldable properties, while other portions are disposed below non-folding areas with stable support. This local quality optimization reduces overall structural complexity while maintaining complete functionality.

AI summary
A display device includes a display module, a first support plate disposed below the display module, a first digitizer disposed below the first support plate, a second digitizer disposed below the first support plate and spaced apart from the first digitizer in a first direction, a second-1 support plate disposed below the first digitizer, and a second-2 support plate disposed below the second digitizer, the second digitizer extends between the first support plate and the second-1 support plate to overlap the second-1 support plate.
