Flexible Display Window With Segmented Rigid Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in protecting themselves from external impacts due to the use of soft materials that provide flexibility but lack sufficient resistance.
Innovation Solution
A flexible display device design incorporating a window with an elastic portion made of soft materials and rigid portions made of hard materials, arranged in patterns such as checkered or striped, which provides both flexibility and sheet resistance against external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the window is made of soft material to provide flexibility, then the flexibility of the display device is improved, but the resistance to external impact deteriorates
Solution Approach 1:
The window is constructed as a composite structure combining a soft elastic portion made of elastomer material with multiple hard rigid portions made of inorganic material. This composite design allows the window to simultaneously achieve flexibility from the elastic portion and impact resistance from the rigid portions, directly resolving the contradiction between flexibility and strength
Solution Approach 2:
The window surface is segmented into multiple rigid portions that are separated from each other and positioned on the elastic portion. This segmentation allows the rigid portions to be distributed across the window surface, providing localized protection while maintaining overall flexibility through the elastic portion that connects and supports these segments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combination of soft and hard materials in the window structure allows for flexibility while effectively resisting external impacts, ensuring the display device's protection and maintaining image resolution.
Implementation Method 1
The elastic portion may be made of a soft material having elastic characteristics
Implementation Method 2
The rigid portion may be made of a hard material

AI summary
A flexible display device includes a flexible display panel, a touch sensing layer on the flexible display panel, and a window on the touch sensing layer. The window may include an elastic portion and a plurality of rigid portions at a surface of the elastic portion and separated from each other. The elastic portion may be made of a soft material having elastic characteristics, and the rigid portion may be made of a hard material. The rigid portion may have a checkered pattern or a striped pattern at the surface of the elastic portion. The flexible display device may also include a barrier film at a surface of the flexible display panel. The barrier film may protect the flexible display panel and the touch sensing layer from external impacts.
