Stretchable Display Panel with Nested Coupling Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible and stretchable display devices lack the ability to dynamically change their shape and display configuration to provide a three-dimensional image experience while maintaining stability and image quality when stretched or curved.
Innovation Solution
A display device featuring a stretchable display panel with a frame that includes coupling parts allowing the panel to elongate vertically, creating a two-dimensional curved surface, providing a three-dimensional image effect and sense of immersion through the use of sub-frames and connecting rods for controlled movement and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is made flexible and stretchable to enable shape changing, then adaptability and versatility are improved, but structural stability and image quality maintenance deteriorate
Solution Approach 1:
The frame is divided into multiple sub-frames (first sub-frame, second sub-frame, etc.) that can move independently relative to each other. Each sub-frame supports a portion of the display panel, allowing the system to achieve shape changing through coordinated movement of segmented components while maintaining local structural stability for image quality
Solution Approach 2:
Connecting rods serve as intermediary elements between sub-frames, enabling controlled relative movement while maintaining structural coherence. These intermediaries transmit forces and constraints appropriately, allowing shape changing without compromising the overall structural integrity needed for stable image display
2Adaptability or versatility
If coupling parts are designed to allow vertical movement for elongation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The coupling parts are designed with nested ring structures where inner circumferential surfaces of one coupling part overlap with outer circumferential surfaces of another. This nesting allows vertical movement and elongation while using shared structural space, reducing overall complexity compared to separate independent coupling mechanisms
Solution Approach 2:
The coupling parts serve multiple functions: they connect display areas to the frame, enable vertical movement for elongation, provide structural support, and facilitate the shape changing mechanism. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity

AI summary
A display device includes a stretchable display panel including a first display area and a second display area, the second display area extending from the first display area in a horizontal direction substantially parallel to the first display area, and a frame including a first coupling part and a second coupling part spaced apart from the first coupling part in the horizontal direction, the second coupling part being moveable in a vertical direction normal to the horizontal direction, wherein the first and second display areas are respectively coupled to the first and second coupling parts, and the second display area is elongated in the vertical direction when the second coupling part moves in the vertical direction.
