Stretchable Display Panel With Orthogonal Through-Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies, such as flat panel displays, lack the ability to expand their display area effectively, limiting their functionality and user experience, especially in foldable and stretchable applications.
Innovation Solution
A display panel design featuring a substrate with a first and second display area, where the second area is stretchable and includes through-parts extending in different directions, allowing for expansion and contraction, integrated with a circuit structure and light emitting diodes, enabling the display device to function as both foldable and stretchable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional flat panel display structure is used, then the display area is fixed and stable, but the display area cannot be expanded or adapted to different configurations
Solution Approach 1:
The display panel is divided into a first display area and a second display area, where the second display area includes through-parts that enable independent stretching and expansion. This segmentation allows different regions to have different functionalities - the first area remains stable while the second area can be expanded, resolving the contradiction between adaptability and stability.
Solution Approach 2:
The second display area is designed with through-parts that allow it to dynamically change its configuration by stretching in specific directions. This dynamic capability enables the display area to be expanded when needed while the first display area maintains its stable, fixed configuration, thus resolving the contradiction between expandability and stability.
2Adaptability or versatility
If the display panel is made flexible and foldable, then the display area can be configured differently, but the structural complexity increases
Solution Approach 1:
The substrate is segmented into different display areas with distinct characteristics - the first display area uses a traditional stable substrate structure, while the second display area incorporates through-parts for flexibility. This segmentation allows foldable functionality to be added only where needed, rather than making the entire substrate complex.
Solution Approach 2:
Different regions of the display panel have different structural qualities - the first display area maintains a simple, stable substrate structure, while the second display area locally incorporates through-parts to enable folding and stretching. This local differentiation adds foldable capability without increasing the overall structural complexity of the entire display panel.
3Area of moving object
If the second display area is stretched to expand the display, then the display area increases, but the alignment with circuit structures becomes misaligned
Solution Approach 1:
The second display area is designed as a dynamic region with through-parts that allow controlled stretching. When stretched, this area expands to increase the display area while the through-parts maintain the structural integrity and alignment relationships with underlying circuit structures, resolving the contradiction between area expansion and alignment precision.
