Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated circuits are used for HDR processing and data conversion, then image quality and resolution capabilities are improved, but power consumption increases
Solution Approach 1:
The patent extracts the data conversion and HDR processing functions from dedicated circuits and relocates them to be performed within the pixel circuit itself. By integrating these functions into the pixel-level circuitry, the system eliminates the need for separate dedicated conversion circuits, thereby reducing overall power consumption while maintaining high image quality and resolution capabilities.
Solution Approach 2:
The pixel circuit is designed to perform its own data conversion and HDR processing operations autonomously. Each pixel circuit includes components that can independently handle gamma correction, luminance adjustment, and resolution conversion without requiring external dedicated processing circuits, enabling the system to serve itself and reduce power consumption.
2Adaptability or versatility
If data conversion is performed for resolution transitions, then display adaptability is improved, but device complexity increases
Solution Approach 1:
The patent divides the data conversion and processing functions into individual pixel circuit modules. Each pixel circuit is segmented to handle specific conversion tasks independently, allowing the system to achieve high display adaptability across different resolutions without requiring a single complex centralized processing unit. This modular segmentation reduces overall device complexity.
Solution Approach 2:
The pixel circuit is designed with universal components that can perform multiple functions including gamma correction, luminance adjustment, and resolution conversion. This multi-functional design allows a single pixel circuit structure to adapt to various display requirements without adding dedicated circuits for each function, thereby reducing device complexity while maintaining high adaptability.
