1Weight of moving object
If a flexible display is made bendable and foldable to enhance miniaturization and portability, then the device becomes thinner and lighter, but the ability to detect and utilize various flexion states for specific operations and user interface functionality is lost
Solution Approach 1:
The flexible display is divided into multiple sensing regions with bend sensors arranged in arrays across different locations. Each sensor segment detects local flexion independently, allowing the system to recognize various global flexion states (bending, folding, rolling, twisting) through coordinated signals from multiple segments, thereby enabling diverse functions while maintaining flexibility.
Solution Approach 2:
The system dynamically adapts its functionality based on real-time detection of flexion states. The controller interprets sensor signals to identify current deformation states and automatically adjusts operational modes, making the display's functional capabilities dynamic and responsive to user manipulation rather than static.
2Adaptability or versatility
If bend sensors are arranged in a predetermined form on the flexible display to detect flexion states, then specific operations and user interface functionality are enabled, but the device complexity increases
Solution Approach 1:
The bend sensor array serves multiple functions simultaneously: it detects bending direction, folding states, rolling程度, twisting angles, and touch interactions. This multi-functional sensor system eliminates the need for separate sensors for each function, reducing overall device complexity while enabling diverse user interface capabilities.
Solution Approach 2:
The flexible display structure itself serves as the mounting substrate for the bend sensors, utilizing the display's inherent flexibility and surface area. The sensors are integrated directly into the display layers, eliminating the need for separate sensor housings or additional structural components, thereby simplifying the overall device architecture.
