Foldable Display Support Plate Lattice for Impact-Resistant Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices are prone to damage from external impacts due to their folding areas having flexible characteristics, necessitating improved impact resistance.
Innovation Solution
A display device design incorporating a support plate with specific openings in its folding part, featuring varying lengths and depths in different directions, and varying widths that gradually decrease, enhancing structural integrity and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the folding area is made flexible to enable folding operations, then the adaptability and portability are improved, but the impact resistance and durability deteriorate
Solution Approach 1:
The support plate is designed with non-uniform opening structures: the first openings have different sizes, shapes, or orientations than the second openings. This creates local variations in mechanical properties across the folding area, providing enhanced impact resistance in specific regions while maintaining overall flexibility for folding operations.
Solution Approach 2:
The support plate is divided into multiple regions with different opening patterns - a first region with first openings and a second region with second openings. This segmentation allows different parts of the folding area to have different mechanical characteristics, balancing flexibility and impact resistance across the structure.
2Ease of operation
If openings are added to the support plate to maintain flexibility, then the ease of operation is improved, but the structural strength deteriorates
Solution Approach 1:
Different regions of the support plate have different opening characteristics - the first openings in the first region provide flexibility for folding operations, while the second openings in the second region are designed to maintain structural strength and prevent excessive deformation during use.
Solution Approach 2:
The first openings and second openings are designed with asymmetric characteristics - they differ in size, shape, orientation, or distribution patterns. This asymmetry allows the support plate to exhibit different mechanical behaviors in different directions and regions, optimizing both flexibility and strength.

AI summary
Disclosed is a display device which includes a display module including a non-folding area and a folding area arranged in a first direction and a support plate including a folding part that overlaps the folding area. An opening extending in a second direction crossing the first direction is defined in the folding part, and the opening includes a first opening defined in a lower surface of the folding part and a second opening defined above the first opening. In the second direction, a first length of the first opening and a second length of the second opening are different from each other.
