Flexible Display Sensor Feedback for Bend Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays in mobile terminals have a limited range of variation before being damaged, making it difficult for users to recognize and manage the extent of bending, which can lead to unintended damage.
Innovation Solution
Incorporating sensors on the flexible display to convert the flex state into electric signals, which are then used by a controller to determine and output visual effects indicating the bent extent, allowing users to be informed and enabling adaptive display configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is made more flexible to enable bending, then adaptability is improved, but the risk of damage increases when bent beyond the limited range
Solution Approach 1:
The patent implements a feedback mechanism by placing sensors on the flexible display to detect the bending degree and providing real-time feedback to the user through visual or haptic cues. This allows users to adjust their handling to avoid exceeding the safe bending range, thus preventing damage while maintaining flexibility.
Solution Approach 2:
The system performs preliminary detection of the flex state before damage can occur. By continuously monitoring the bending degree through sensors and providing advance warning to the user, the system prevents the harmful action of over-bending before it happens.
2Measurement precision
If sensors are added to detect flex state, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the flexible display into multiple segments by placing multiple sensors at different locations. Each sensor independently detects the flex state at its specific location, providing comprehensive coverage and precise measurement of the overall bending condition through distributed segmentation.
Solution Approach 2:
The sensors serve multiple functions: they detect the flex state, provide feedback to the user, and enable the controller to adjust display configurations. This multi-functionality reduces the need for separate components and justifies the added complexity by delivering multiple benefits from a single sensor system.
3Adaptability or versatility
If the display configuration is dynamically adjusted based on flex state, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic display configuration that automatically adjusts based on the real-time flex state detected by sensors. The display can change its operational mode, orientation, or content presentation dynamically in response to bending, providing adaptability without requiring manual user intervention or complex mechanical adjustments.
