Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard compensation data is used for a display panel under a first dimming mode, then the compensation data can be obtained, but the compensation effect deteriorates when switching to a second dimming mode due to gamma value differences
Solution Approach 1:
The patent applies parameter changes by calculating a second adjustment coefficient based on the first adjustment coefficient and gamma values of different dimming modes. This coefficient transformation enables the compensation data to adapt to different gamma values without requiring separate compensation data for each dimming mode, thus resolving the contradiction between adaptability and precision.
Solution Approach 2:
The patent implements dynamics by making the compensation data adjustable and adaptable rather than fixed. The system dynamically calculates adjustment coefficients based on the current dimming mode and brightness value, allowing the compensation data to change adaptively across different operating conditions, thereby maintaining high compensation precision across modes.
2Manufacturing precision
If compensation data is generated for each dimming mode separately, then the compensation precision for each mode is improved, but the storage requirements and manufacturing complexity increase
Solution Approach 1:
The patent applies universality by creating a single compensation data set that can serve multiple dimming modes through mathematical transformation. The first adjustment coefficient serves as a universal basis that can be transformed into second adjustment coefficients for different dimming modes, eliminating the need for separate compensation data for each mode while maintaining high precision.
Solution Approach 2:
The patent uses parameter changes to reduce complexity by transforming compensation data through calculation rather than storing multiple versions. The system calculates adjustment coefficients on-demand based on gamma values, reducing storage requirements and simplifying the compensation system architecture while maintaining mode-specific precision.
3Manufacturing precision
If compensation data is adjusted for current display brightness value, then the compensation effect is improved, but the calculation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing adjustment coefficients for different brightness values during manufacturing. During actual operation, the system simply retrieves the pre-calculated coefficient corresponding to the current brightness value, avoiding complex real-time calculations while maintaining high compensation precision at each brightness level.
