Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polynomial regression algorithm is applied to derive optimal voltage values, then flicker phenomenon is minimized and image quality is improved, but device complexity increases
Solution Approach 1:
The patent applies polynomial regression algorithm in advance to derive optimal voltage values and generate compensation data before actual display operation. This preliminary computation creates lookup tables and compensation parameters that simplify real-time operation, resolving the contradiction by performing complex calculations beforehand rather than during operation.
Solution Approach 2:
The system uses the display device's own sampled basic data to generate its own compensation data through polynomial regression. The device self-calibrates by utilizing its own operational characteristics, eliminating the need for external calibration equipment or additional hardware components, thus improving image quality without proportionally increasing device complexity.
2Reliability
If polynomial regression algorithm is applied to minimize flicker phenomenon, then image quality is improved, but power consumption increases
Solution Approach 1:
The polynomial regression computation and optimal voltage derivation are performed in advance during initialization or calibration phases. The resulting compensation data is stored for reuse during normal operation, avoiding repeated power-intensive calculations during active display periods, thus minimizing ongoing power consumption while maintaining improved image quality.
Solution Approach 2:
The system applies polynomial regression selectively to derive compensation data rather than continuously computing during operation. By performing the computationally intensive algorithm only when necessary (initialization, parameter changes) and using the results for multiple operations, the patent achieves flicker minimization without proportionally increasing power consumption.
3Use of energy by moving object
If polynomial regression algorithm is applied to prevent leakage current, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The system utilizes its own sampled basic data and internal polynomial regression capability to generate compensation data that prevents leakage current. By using self-generated compensation parameters rather than external control systems or additional hardware, the patent achieves leakage current prevention with minimal increase in device complexity.
