Flexible Display Support Plate With Regional Hole Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of electronic devices with flexible display screens is compromised due to the challenge of balancing bending performance and structural strength in support assemblies, particularly when subjected to impacts.
Innovation Solution
A support plate with targeted through-holes of varying sizes in different areas is used to balance bending performance and structural strength, with larger holes in areas requiring greater flexibility and smaller holes in areas needing more structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the support plate uses a uniform structure, then the manufacturing is simple, but the bending performance and structural strength cannot be balanced
Solution Approach 1:
The support plate employs through-holes of different sizes distributed in different regions to create local variations in structural properties. Larger through-holes are positioned in areas requiring greater flexibility, while smaller through-holes are placed in areas needing enhanced structural strength, thereby achieving spatially optimized bending performance and impact resistance without compromising manufacturing feasibility
2Ease of operation
If the support plate has larger through-holes, then the bending performance is improved, but the structural strength decreases
Solution Approach 1:
The support plate employs through-holes of different sizes distributed in different regions to create local variations in structural properties. Larger through-holes are positioned in areas requiring greater flexibility, while smaller through-holes are placed in areas needing enhanced structural strength, thereby achieving spatially optimized bending performance and impact resistance
Solution Approach 2:
The support plate is segmented into multiple regions with different through-hole configurations. This segmentation allows different parts of the support plate to have tailored mechanical properties, with some regions optimized for flexibility and others for strength, resolving the contradiction between overall bending performance and structural integrity
3Strength
If the support plate has smaller through-holes, then the structural strength is improved, but the bending performance decreases
Solution Approach 1:
The support plate employs through-holes of different sizes distributed in different regions to create local variations in structural properties. Larger through-holes are positioned in areas requiring greater flexibility, while smaller through-holes are placed in areas needing enhanced structural strength, thereby achieving spatially optimized bending performance and impact resistance
4Reliability
If the support plate uses through-holes of different sizes, then the impact resistance is improved, but the manufacturing complexity increases
Solution Approach 1:
The support plate employs through-holes of different sizes distributed in different regions to create local variations in structural properties. Larger through-holes are positioned in areas requiring greater flexibility, while smaller through-holes are placed in areas needing enhanced structural strength, thereby achieving spatially optimized bending performance and impact resistance
Solution Approach 2:
The invention varies the parameter of through-hole size across different regions of the support plate. This parameter change allows optimization of mechanical properties (impact resistance and bending performance) in different areas while maintaining a relatively simple manufacturing process through standardized hole patterns

AI summary
A display panel includes a flexible display screen and a support plate. The flexible display screen includes a flexible section and switches between at least a flat state and a deformed state through the flexible section. The support plate is located on a non-display output side of the display screen and includes a target section corresponding to the flexible section of the display screen. The target section includes a first area and a second area arranged along a first direction. The first area includes a first through-hole arranged along a second direction. The second area includes a second through-hole arranged along the second direction. the first through-hole and the second through-hole have different sizes. The second direction is different from the first direction.
