Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate sensors are included for automatic display calibration, then display calibration precision is improved, but device size increases
Solution Approach 1:
The flexible display panel serves dual functions: as a display device and as a sensor for detecting external light and displayed images. When bent, the display panel can sense the adjustment image and external light conditions, eliminating the need for separate calibration sensors and maintaining compact device size while achieving automatic calibration
Solution Approach 2:
The display panel performs self-calibration by using its own bending state to trigger the calibration process. The system automatically detects when the display is bent, captures the adjustment image, and processes calibration data without requiring external sensors or manual user intervention
2Device complexity
If manual display calibration adjustment is performed, then device complexity is reduced, but calibration precision deteriorates
Solution Approach 1:
The system performs automatic calibration by detecting when the display is bent and automatically capturing adjustment images and processing calibration data, eliminating the need for manual user adjustment while achieving precise calibration results through automated image processing
3Loss of time
If automatic display calibration is implemented, then calibration time is reduced, but device complexity increases
Solution Approach 1:
The display panel automatically initiates calibration when bent by the user, eliminating the need for separate calibration triggers or complex calibration interfaces. The system self-manages the entire calibration process from detection to execution, reducing both time and complexity
Solution Approach 2:
Instead of using separate sensors to detect calibration needs, the system inverts the approach by using the display panel itself as the sensor. The bending action that deforms the display also triggers the calibration process, combining the trigger mechanism with the display function
