Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate ambient light sensors are used to detect brightness and color temperature, then detection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple detection functions (brightness detection and color temperature detection) into a single integrated detection module. The detection module includes first detection units for brightness detection and second detection units for color temperature detection, all integrated within the same display panel structure. This merging eliminates the need for separate sensors, reducing manufacturing costs while maintaining detection accuracy through the coordinated work of multiple detection units within the integrated module.
2Adaptability or versatility
If complex detection systems are implemented to adjust display settings, then display adaptability is improved, but device complexity increases
Solution Approach 1:
The detection module is designed with multi-functionality, where the same integrated module performs both brightness detection and color temperature detection. The first detection units detect ambient light brightness to determine first display settings, while the second detection units detect color temperature to determine second display settings. This universal detection module handles multiple detection tasks, providing comprehensive display adaptability without requiring separate complex detection systems for each function.
3Reliability
If multiple separate sensors are installed for brightness and color temperature detection, then detection reliability is improved, but power consumption increases
Solution Approach 1:
The patent merges the brightness detection function and color temperature detection function into a single integrated detection module that operates as a unified system. Instead of running separate sensors independently, the integrated module coordinates the first detection units and second detection units to work together, sharing common circuitry and processing resources. This reduces redundant power consumption while maintaining the reliability of detection through the combined functionality of multiple detection units within the same operational framework.
