Bendable Display Panel Shape Control via Elastic Adjusting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bendable display panels face challenges in maintaining a consistent bent shape without external support, as existing technologies struggle to uniformly maintain both flat and bending states without deformation.
Innovation Solution
A display device featuring a flexible substrate with a bending adjusting member that can switch between flat and bending states using external forces, maintaining shape through an adhesive layer and concave recesses, allowing for controlled curvature and elasticity in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible substrate is used to enable bending, then the display panel can be bent, but the display panel cannot uniformly maintain its shape in both flat and bending states
Solution Approach 1:
The bending adjusting member is divided into multiple independent bending areas by concave recesses, allowing each segment to maintain uniform shape independently while enabling overall flexibility of the display panel
Solution Approach 2:
The bending adjusting member utilizes elastic deformation to change between flat and bending states, maintaining shape uniformity through controlled parameter changes in the material's physical state
2Stability of the object's composition
If external support is used to maintain bent shape, then the bent shape can be maintained, but the device complexity increases
Solution Approach 1:
The bending adjusting member is self-contained and integrated into the display panel structure, using internal elastic properties rather than external support structures to maintain bent shapes
Solution Approach 2:
The bending adjusting member combines the functions of structural support, shape maintenance, and flexibility control into a single integrated component fixed to the rear surface of the display panel

AI summary
A display device including a bendable display panel, and an operation method thereof. The display device includes a display panel including a flexible substrate and a display unit and a bending adjusting member fixed to a rear surface of the display panel, and changeable between a flat state and a bending state by external force. The bending adjusting member is bent in a width direction to form a curvature, has elasticity in the width direction and a longitudinal direction, and is maintained in any one state between the flat state and the bending state under a condition of non-application of external force.
