Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-screen display devices with two independent display panels are costly and difficult to design due to high design requirements, and the auxiliary display panel typically has limited content variety as it is usually an ink screen.
Innovation Solution
A display device featuring a flexible display panel that bends around a middle frame to create a main display panel region, an auxiliary display panel region, and a bending region, with both regions being color screens and driven by a single driver circuit, reducing costs and design complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent display panels are used to achieve dual-screen functionality, then the display capability is improved, but the device complexity and cost increase
Solution Approach 1:
The single flexible display panel is segmented into two functional regions: a main display panel region and an auxiliary display panel region. This segmentation allows the panel to serve multiple purposes (dual-screen functionality) while physically remaining as one integrated component, thereby reducing device complexity and cost while maintaining adaptability.
Solution Approach 2:
The single flexible display panel is designed to perform multiple functions by creating distinct display regions. The same physical panel can function as both a main display and an auxiliary display, eliminating the need for separate independent display panels and reducing overall device complexity.
2Adaptability or versatility
If two independent display panels are used, then dual-screen functionality is achieved, but manufacturing cost increases
Solution Approach 1:
Two display functions are merged into a single flexible display panel. By combining the main display and auxiliary display into one physical panel with distinct regions, the manufacturing process is simplified and material costs are reduced compared to producing and assembling two separate independent display panels.
Solution Approach 2:
The single flexible display panel is designed to perform multiple functions (main display and auxiliary display) simultaneously. This multi-functionality approach reduces the total number of components needed, thereby lowering manufacturing costs while maintaining dual-screen capability.
3Device complexity
If a single flexible display panel is bent around a middle frame to create dual-screen functionality, then device complexity is reduced, but the bending region requires special structural design
Solution Approach 1:
The flexible display panel is bent into a curved configuration around the middle frame, creating a bending region with a specific arc shape. This curvature allows the panel to wrap around the frame structure, enabling dual-screen functionality while managing the structural requirements of the bending region through controlled geometric design.
4Ease of manufacture
If the flexible display panel is bent around the middle frame, then dual-screen functionality is achieved with lower cost, but the opening in the middle frame requires precise dimensional matching
Solution Approach 1:
The middle frame is designed with a localized opening feature that precisely matches the bending region of the flexible display panel. This local quality approach focuses precision requirements on the specific interface area (the opening and bending region) rather than the entire structure, enabling cost-effective manufacturing while maintaining necessary dimensional accuracy at the critical interface.
