Flexible Display Support Member for Sliding-Scrolling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sliding-scrolling mechanisms for flexible display panels lack adequate support when in a flattened state, leading to potential damage and poor user experience due to inadequate touch sensitivity.
Innovation Solution
A flexible display device is designed with a support member that includes rigid and flexible support plates, which are rolled on a sliding reel and configured to support the flexible display panel when expanded, ensuring proper alignment and reduced warpage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display panel is made thin and flexible for sliding-scrolling application, then the adaptability and portability are improved, but the structural strength and support capability deteriorate, causing the panel to be easily damaged when in flattened state
Solution Approach 1:
A support member is introduced as an intermediary component between the sliding reel and the flexible display panel. This support member provides mechanical reinforcement to the thin flexible panel when it is in the flattened state, preventing damage while maintaining the panel's flexibility and sliding-scrolling functionality. The support member acts as a mediator that enables the thin panel to withstand operational stresses.
2Ease of operation
If the flexible display panel is made thin for better flexibility, then the ease of operation is improved, but the touch sensitivity deteriorates due to inadequate support in flattened state
Solution Approach 1:
The support member serves as a mediator that provides adequate structural support to the thin flexible display panel, enabling it to maintain proper touch sensitivity while preserving its flexibility. Without this intermediary support, the thin panel would be too soft to provide accurate touch feedback.
3Strength
If a rigid support structure is added to support the flexible display panel in flattened state, then the strength and support capability are improved, but the device complexity increases
Solution Approach 1:
The support member is designed to be dynamically deployable rather than permanently fixed. It can be extended when needed to provide support and retracted when not needed, transforming the static complex structure into a dynamic one that only adds complexity when actually required for support.
Solution Approach 2:
The support member is nested within or integrated with the sliding reel mechanism, allowing it to be stored compactly when not in use. This nesting approach minimizes the space required and reduces the overall device complexity while maintaining the necessary support capability when deployed.
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 solution provides robust support to the flexible display panel in its expanded state, reducing the risk of damage and improving touch sensitivity, thus enhancing the overall user experience.
Implementation Method 1
a coil is wound outside the rigid support plate; and the flexible display panel includes a metal support layer which is located on a side of the flexible display panel attaching with the support member, the material of the metal support layer is magnetically conductive metal, and the metal support layer is able to be attached to the rigid support plate which is energized
