Flexible Screen Support Assembly for Curved Display Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with curved screens, such as waterfall screens, face issues with inaccessible content at the edge of the screen due to curvature, leading to viewing inconveniences, edge reflection problems, and mistouch during full-screen operations.
Innovation Solution
A support assembly is disposed on the back side of the flexible screen portion, allowing it to switch between a curved and a flat state. This adjustment facilitates different use scenarios and user groups by ensuring convenient viewing and function triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the screen uses a curved structure to improve display aesthetics and hand feel, then the visual display effect and hand feel are improved, but the accessibility of content at the edge of the screen deteriorates due to curvature and light propagation
Solution Approach 1:
The patent applies the dynamics principle by enabling the screen to switch between curved and flat states. The support assembly can change its shape to transition the flexible screen portion from a curved configuration to a flat configuration, allowing the screen to adapt its geometry based on operational requirements. This resolves the contradiction by providing a flat state for optimal edge content accessibility when needed, while maintaining the curved state for aesthetic purposes and hand feel during other scenarios.
2Shape
If the screen maintains a curved structure for aesthetic design, then the visual display effect is improved, but light reflection at the edge of the screen deteriorates due to the curvature
Solution Approach 1:
The patent resolves the reflection problem by implementing a dynamic support assembly that can flatten the flexible screen portion when needed. In flat state, the screen surface becomes perpendicular to the viewing angle, eliminating the curved surface reflection that causes harmful light propagation. This allows the system to maintain aesthetic curved design during display scenarios while eliminating reflection interference during operations requiring precise light control.
3Area of stationary object
If the screen uses a curved structure for full-screen operation, then the display area is maximized, but function triggering on the curved part becomes inconvenient and leads to mistouch
Solution Approach 1:
The patent applies dynamics by enabling the flexible screen portion to transition to a flat state during operations that require precise touch input. When the support assembly is in the second state, the flexible screen portion becomes flat, providing a stable surface for accurate finger placement and touch triggering. This eliminates the mistouch problem associated with curved surfaces while preserving the full-screen display area when the support assembly is in the first state.
4Device complexity
If the screen is designed as a single-state curved structure, then the manufacturing complexity is reduced, but the adaptability to different use environments deteriorates
Solution Approach 1:
The patent resolves the adaptability contradiction by implementing a support assembly with multiple states (first state for curved configuration, second state for flat configuration). This allows the electronic device to adapt to different use environments - maintaining the curved state for aesthetic display scenarios and switching to the flat state for operational scenarios requiring precision. The dynamic capability adds versatility without excessive complexity, as the support assembly integrates with the existing flexible screen structure.
