Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices are prone to wrinkles and lack sufficient impact resistance, which affects surface quality and durability.
Innovation Solution
A display device with a support plate featuring distinct flat and folding parts, and a cover layer settled into a folding groove, providing enhanced structural integrity and impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display device uses a thin support plate to maintain flexibility, then the device can be bent and folded, but the impact resistance and surface quality deteriorate causing wrinkles and deformation
Solution Approach 1:
The cover layer is settled into an etched space within the support plate, creating a nested structure where one component is placed inside another. This allows the cover layer to be positioned within a recessed area of the support plate, providing impact resistance while maintaining the overall thin profile and flexibility of the display device.
Solution Approach 2:
The support plate features a localized etched space with different thickness characteristics compared to the rest of the plate. This local variation in structure provides enhanced protection and surface quality at the specific location where the cover layer is settled, without compromising the overall flexibility of the entire support plate.
2Ease of manufacture
If the support plate structure is simplified to reduce manufacturing complexity, then production becomes easier, but the ability to prevent foreign substance ingress and maintain surface quality deteriorates
Solution Approach 1:
The etched space creates a nested structure where the cover layer is settled within a recessed area of the support plate. This design prevents foreign substances from entering the openings while maintaining a relatively simple manufacturing process that involves etching the support plate to create the settling space.
3Strength
If a thicker support plate is used to improve impact resistance, then external impact protection increases, but the flexibility and ability to fold deteriorate
Solution Approach 1:
By settling the cover layer into an etched space within the support plate, the structure provides enhanced impact resistance through the nested configuration without requiring a significant increase in the overall thickness of the support plate. This maintains the flexibility needed for folding while providing improved protection.
Solution Approach 2:
The etched space creates a localized region with different structural properties that enhances impact resistance at specific areas without requiring the entire support plate to be thicker, thereby preserving the overall flexibility of the device.

AI summary
A display device includes a display panel and a support plate disposed below the display panel, the support plate including a first flat part, a second flat part, and a central or folding part disposed between the first and second flat parts. The folding part may have a thickness different than each of the first and second flat parts.
