Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display panel uses preset color reproduction features, then the display structure is simple, but the color reproduction accuracy varies under different environmental light states
Solution Approach 1:
The controller pre-stores multiple color reproduction feature sets (including color temperature and gamma values) corresponding to different environmental light states. Before displaying an image, the controller determines the current environmental light state and selects the appropriate pre-stored color reproduction features, avoiding real-time complex calculations and maintaining simple display structure while achieving accurate color reproduction.
Solution Approach 2:
The patent changes the color reproduction parameters (color temperature and gamma values) based on the determined environmental light state. By adjusting these parameters dynamically according to ambient lighting conditions, the display achieves accurate color reproduction across different environments without requiring complex structural modifications.
2Measurement precision
If the display adjusts color distribution dynamically, then the color reproduction accuracy improves, but the processing complexity increases
Solution Approach 1:
The controller pre-calculates and stores multiple sets of color reproduction features corresponding to different environmental light states. This preliminary preparation eliminates the need for complex real-time calculations during image display, reducing processing complexity while maintaining high color reproduction accuracy through dynamic selection of pre-computed parameters.
Solution Approach 2:
The patent dynamically changes color distribution parameters (color temperature and gamma values) based on the determined environmental light state. This parameter adjustment approach achieves accurate color reproduction by selecting from pre-defined parameter sets rather than performing complex real-time optimization, thereby reducing processing complexity.
3Object-affected harmful factors
If the display maintains consistent color temperature across frames, then viewer fatigue is reduced, but the adaptability to different image characteristics decreases
Solution Approach 1:
The controller pre-stores multiple color reproduction feature sets corresponding to different environmental light states and image characteristics. By determining the current environmental light state and selecting the appropriate pre-stored features, the system maintains consistent color temperature within each environmental context, reducing viewer fatigue while adapting to different imaging conditions through the availability of multiple pre-configured feature sets.
Solution Approach 2:
The patent adjusts color temperature parameters based on the determined environmental light state and image characteristics. By changing parameters dynamically according to environmental conditions while maintaining consistency within each condition, the display reduces viewer fatigue associated with color fluctuations while remaining adaptable to different imaging scenarios.
