Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If normal display output is provided under poor viewing conditions, then display function is maintained, but eye damage risk increases
Solution Approach 1:
The display output is dynamically adjusted based on real-time viewing condition recognition results and content classification. The system continuously monitors viewing conditions (distance, angle, ambient light) and adapts display parameters (brightness, contrast, color temperature, pixel arrangement) to protect eyes under varying conditions while maintaining normal display function when conditions are good.
Solution Approach 2:
The patent changes multiple display parameters simultaneously based on viewing conditions and content type: brightness adjustment, contrast modification, color temperature shifting, and pixel arrangement reconfiguration. These parameter changes enable the display to adapt its output characteristics to reduce eye strain while preserving display functionality across different viewing scenarios.
2Object-affected harmful factors
If display output is adjusted to protect eyes, then eye protection is improved, but display quality may deteriorate
Solution Approach 1:
The patent applies different adjustment strategies to different content types (text, image, video, gaming) and different viewing condition scenarios. Instead of uniform adjustment, the system tailors display parameter modifications to specific content characteristics and viewing conditions, preserving display quality for each content type while providing eye protection. For example, text content receives different adjustments compared to image content.
Solution Approach 2:
The system dynamically selects and applies appropriate adjustment algorithms based on real-time content classification and viewing condition assessment. This dynamic approach ensures that display quality is maintained by choosing the most suitable adjustment strategy for each specific scenario rather than applying fixed adjustments that would compromise quality.
3Measurement precision
If viewing condition recognition and content classification are performed, then eye protection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the processing system into distinct functional modules: viewing condition recognition circuit, content classification circuit, and display adjustment circuit. Each module performs a specific function, making the overall complex system manageable and maintainable. The segmentation allows independent optimization of each module while achieving high overall accuracy.
Solution Approach 2:
The processing circuits are designed to handle multiple functions: viewing condition detection, content type classification, and display parameter determination. This multi-functionality reduces the need for separate dedicated circuits for each function, thereby managing device complexity while maintaining high measurement and classification accuracy.

AI summary
A display control apparatus includes a viewing condition recognition circuit, a content classification circuit, and a display adjustment circuit. The viewing condition recognition circuit recognizes a viewing condition associated with a display device to generate a viewing condition recognition result. The content classification circuit analyzes an input frame to generate a content classification result of contents included in the input frame. The display adjustment circuit generates an output frame by performing image content adjustment according to the viewing condition recognition result and the content classification result, wherein the image content adjustment comprises at least content-adaptive adjustment applied to at least a portion of pixel positions of the input frame based on the content classification result.
