Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display panel is increased, then the visual quality is improved, but the manufacturing cost increases due to more sub-pixels required
Solution Approach 1:
The patent uses sub-pixel rendering to create virtual sub-pixels through software algorithms, copying the visual effect of having more physical sub-pixels without actually manufacturing them. The system renders images at a lower resolution and uses sub-pixel level control to simulate higher resolution display, thereby achieving high visual quality without increasing manufacturing cost
Solution Approach 2:
The patent changes the parameter of sub-pixel arrangement configuration between different modes (e.g., RGB, BGR, GRB, RBG). By dynamically switching between multiple sub-pixel arrangement parameters, the system can adapt to different display requirements and achieve versatile display capabilities without requiring physical hardware changes, thus avoiding increased manufacturing cost
2Measurement precision
If the resolution of the display panel is increased, then the visual quality is improved, but the data processing complexity increases
Solution Approach 1:
The patent segments the image data processing into multiple stages: full-resolution image processing, sub-pixel rendering conversion, and arrangement-specific optimization. By dividing the complex high-resolution data processing into manageable segments, the system reduces the computational burden at each stage while maintaining overall visual quality
Solution Approach 2:
The patent dynamically changes data processing parameters based on the selected sub-pixel arrangement mode. By pre-configuring conversion algorithms for different arrangement patterns (RGB, BGR, GRB, RBG), the system avoids complex real-time calculations and reduces data processing complexity through parameter-based adaptation
3Adaptability or versatility
If different sub-pixel rendering arrangements are supported, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal conversion apparatus that can handle multiple sub-pixel arrangement types (RGB, BGR, GRB, RBG) through a single integrated system. The conversion circuit is designed with multi-functionality to support various arrangement patterns, eliminating the need for separate dedicated circuits for each pattern and thereby reducing overall device complexity
Solution Approach 2:
The patent uses parameter-based configuration to support different sub-pixel arrangements. By changing operational parameters rather than physical structure, the system achieves adaptability across multiple arrangements without increasing hardware complexity. The conversion circuit responds to control signals that define the target arrangement pattern, enabling flexible adaptation
