Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed overdriving value is used, then the device complexity is reduced, but the display quality deteriorates when viewing angles vary
Solution Approach 1:
The patent implements dynamic overdriving value adjustment by calculating viewing angles through position detection and updating overdriving values in real-time. The system transitions from static fixed values to dynamic adaptive values that change based on user position, thereby maintaining optimal display quality across different viewing angles without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The patent changes the overdriving value parameter based on detected user position and calculated viewing angles. By establishing correspondence between position data, viewing angle calculations, and overdriving value adjustments, the system optimizes display performance for different viewing conditions. This parameter adaptation resolves the contradiction by enabling quality maintenance without fixed complexity.
2Manufacturing precision
If overdriving values are adjusted according to viewing angle, then the display quality is improved, but the device complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting user position, calculating viewing angles, and determining appropriate overdriving values without external intervention. The controller autonomously processes position data, applies calculation formulas, and updates display parameters, eliminating the need for complex manual control mechanisms while maintaining high display quality.
Solution Approach 2:
The patent implements a feedback loop where user position is continuously detected, viewing angles are calculated based on position changes, and overdriving values are adjusted accordingly. This closed-loop system ensures optimal display quality is maintained through continuous adaptation, managing complexity through automated feedback-driven adjustment rather than static configuration.
3Speed
If real-time overdriving value adjustment is implemented, then the response speed is improved, but the processing time increases
Solution Approach 1:
The patent pre-establishes the framework for real-time adjustment by detecting user position and calculating viewing angles continuously. By preparing position data and applying calculation formulas in advance, the system minimizes processing delays during actual display updates. The preliminary detection and calculation frameworks enable rapid overdriving value adjustment without significant processing overhead.
