Flexible Display Support Plate Layout for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack sufficient impact resistance, particularly in flexible designs that undergo bending and folding operations, leading to potential damage and reduced durability.
Innovation Solution
A display device design featuring a support plate with a first area and a second area containing openings, along with a display panel comprising overlapping first and second display areas with varying pixel circuit and light emitting element configurations, and reinforced with a reinforcement member of lower elastic modulus, enhancing structural integrity and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device undergoes bending and folding operations, then adaptability and ease of operation are improved, but impact resistance and structural integrity deteriorate
Solution Approach 1:
The support plate is divided into a first area with a planar support surface and a second area with multiple openings. This segmentation allows different regions to serve different functions: the first area provides structural support while the second area with openings reduces weight and material usage, thereby improving flexibility without significantly compromising overall strength
Solution Approach 2:
The display device employs a composite structure combining a support plate with selective opening patterns and a display panel with varying pixel circuit configurations. This composite design optimizes the balance between flexibility and impact resistance by strategically placing structural elements and openings in different regions
2Weight of moving object
If the support plate includes multiple openings in the second area, then weight is reduced and flexibility is improved, but structural integrity and impact resistance worsen
Solution Approach 1:
The support plate features local quality variation with a first area having a planar support surface for structural integrity and a second area with multiple openings for weight reduction. The display panel similarly has different pixel circuit configurations in different regions, optimizing local properties to balance weight and strength
Solution Approach 2:
Dividing the support plate into regions with and without openings creates a segmented structure that reduces overall weight while maintaining necessary structural integrity in critical areas, thereby improving flexibility without excessive weight loss
3Measurement precision
If pixel circuits are disposed in both first and second display areas, then display resolution is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The display panel implements local quality by disposing pixel circuits in both the first display area (overlapping with planar support surface) and the second display area (overlapping with openings). This allows different regions to have optimized pixel densities and configurations, improving overall resolution while managing complexity through regional differentiation
