Foldable Display Support Structure With Differential Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly flexible and foldable ones, lack sufficient impact resistance, which can lead to damage during handling and use.
Innovation Solution
A display device design incorporating a panel support member with a differential pattern of spacers of varying heights and a barrier film to enhance impact resistance, including a buffer layer and adhesive layers for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid support structure is used to enhance impact resistance, then the impact resistance improves, but the flexibility and foldability of the display device deteriorates
Solution Approach 1:
The support member is divided into multiple regions with different spacer heights (first spacers with greater height, second spacers with lesser height), creating a segmented structure that provides varying degrees of support and flexibility in different areas, allowing the display device to resist impact while maintaining foldability
Solution Approach 2:
Different regions of the support member are assigned different structural properties through the differential spacer heights, with taller spacers providing stronger support in areas requiring impact resistance and shorter spacers allowing greater flexibility in areas requiring bendability,实现ing localized optimization of both strength and flexibility
2Strength
If the spacer height is increased to improve impact resistance, then the protection capability improves, but the uniformity of support and potential flexibility deteriorates
Solution Approach 1:
The support member features a differential pattern where first spacers have greater heights and second spacers have lesser heights, creating locally optimized support zones that provide enhanced impact resistance where needed while maintaining appropriate flexibility in other areas, resolving the contradiction between uniform support and localized protection
3Device complexity
If a simple single-layer support structure is used, then the device complexity is reduced, but the impact resistance and protection capability deteriorates
Solution Approach 1:
The support member is segmented into multiple functional zones with different spacer heights arranged in a differential pattern, creating a multi-functional structure that provides both impact resistance and flexibility control within a single integrated component, avoiding the need for multiple separate layers while achieving enhanced protection
Solution Approach 2:
The support member with differential spacer heights performs multiple functions simultaneously: it provides impact resistance through taller spacers, maintains flexibility through shorter spacers, and offers structural support across different regions, making a single component multi-functional and reducing overall device complexity
