Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in efficiently managing multiple display areas and electrical paths to optimize screen control and user experience during state transitions.
Innovation Solution
The electronic device employs a flexible display with multiple display areas and utilizes distinct electrical paths for each area, controlled by a processor to manage screen display across different states, including rolling and unfolding configurations, with output selection circuitry to activate or deactivate paths as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display with multiple display areas is used to support extended display functionality, then the adaptability and versatility of the device is improved, but the device complexity increases due to multiple electrical paths and state management requirements
Solution Approach 1:
The flexible display is divided into multiple independent display areas (first display area and second display area) that can be independently controlled through separate electrical paths. This segmentation allows each area to be managed independently, reducing the complexity of managing the entire display system as a single unit while maintaining versatility.
Solution Approach 2:
The display system dynamically switches between different operational states (first state with rolled configuration and second state with extended configuration) by activating or deactivating specific electrical paths based on the current physical state of the flexible display. This dynamic adaptation allows the system to optimize performance for each state without requiring permanent complex wiring for all possible configurations.
2Ease of operation
If distinct electrical paths are used for each display area to enable independent control, then the ease of operation is improved, but the device complexity increases due to additional circuitry and control logic
Solution Approach 1:
The processor is designed to handle multiple functions through a unified control architecture that manages both the first electrical path and second electrical path. This multi-functional design allows the same processing unit to control different display areas independently without requiring separate control units, thereby improving ease of operation while limiting the increase in device complexity.
3Volume of moving object
If the flexible display is rolled into the housing to reduce visible area, then the compactness is improved, but the area of moving object decreases reducing display functionality
Solution Approach 1:
The flexible display system dynamically changes its physical configuration between rolled and extended states, allowing it to adapt between compact storage and expanded functionality. The system can switch between these states as needed, providing both compactness when rolled and extended display functionality when unfolded, thereby resolving the contradiction between volume and adaptability.
