Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the ambient light detection module is used to detect ambient light, then the display screen brightness can be adjusted, but the detection data is inaccurate due to interference from the display module's light
Solution Approach 1:
The patent extracts and removes the harmful light interference from the detection data by calculating the light contribution from each pixel of the first display module and subtracting it from the ambient light detection value, thereby eliminating the interference effect and improving detection accuracy
Solution Approach 2:
The patent introduces an intermediary processing step that calculates the light contribution from display pixels and uses this intermediate information to adjust the detection data, serving as a mediator between the raw detection data and the final accurate ambient light value
