Foldable Display Support Plate Openings for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices, particularly foldable ones, are prone to damage from external impacts due to their folding areas having weak impact resistance.
Innovation Solution
The display device incorporates a support plate with strategically designed openings in its folding part, featuring varying lengths and depths in different directions, and 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 operation, then the display device achieves foldability and compactness, but the impact resistance of the folding area deteriorates
Solution Approach 1:
The support plate is divided into multiple regions with different opening configurations: a first region with a first opening and a second region with a second opening. This segmentation allows different parts of the support plate to have different structural characteristics - the first region provides flexibility for folding while the second region provides strength for impact resistance.
Solution Approach 2:
Different regions of the support plate are given different local qualities through varying opening designs. The first opening in the first region has different dimensions and characteristics compared to the second opening in the second region, allowing each area to optimize its properties for specific functions - flexibility where needed and strength where needed.
2Ease of operation
If openings are designed in the folding part to improve flexibility, then the folding operation becomes easier, but the impact resistance deteriorates
Solution Approach 1:
The support plate is divided into multiple regions with different opening configurations: a first region with a first opening and a second region with a second opening. This segmentation allows different parts of the support plate to have different structural characteristics - the first region provides flexibility for folding while the second region provides strength for impact resistance.
Solution Approach 2:
The first opening and second opening are designed with asymmetric characteristics - different sizes, shapes, and positions. This asymmetry allows the openings to serve different functional purposes: the first opening facilitates folding operation while the second opening maintains structural strength and impact resistance.
3Device complexity
If the support plate structure is simplified to reduce manufacturing complexity, then the manufacturing cost decreases, but the impact resistance of the folding area deteriorates
Solution Approach 1:
The support plate is divided into multiple regions with different opening configurations: a first region with a first opening and a second region with a second opening. This segmentation allows different parts of the support plate to have different structural characteristics - the first region provides flexibility for folding while the second region provides strength for impact resistance.

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.
