Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed scanning order (top-down or bottom-up) is used for gate-driver control signals, then the control circuit is simple, but power consumption increases for special images like Horizontal Stripes
Solution Approach 1:
The patent applies dynamics by making the scanning order adjustable rather than fixed. The gate driver control circuit can dynamically change the scanning sequence based on image characteristics, transitioning from a static top-down or bottom-up scan to an adaptive scan pattern that reduces power consumption for specific images like Horizontal Stripes while maintaining simplicity in the control circuit design
Solution Approach 2:
The patent changes the parameter of scanning order from fixed to variable. By allowing the scanning sequence to be reconfigured based on image data, the system optimizes power consumption without significantly increasing circuit complexity. The control circuit can modify scan parameters dynamically to match different display requirements
2Device complexity
If fixed scanning order is used for all images, then the control circuit is simple, but power consumption cannot be optimized for special images
Solution Approach 1:
The system introduces dynamic adaptability to the scanning order based on image characteristics. For special images like Horizontal Stripes, the control circuit can switch to an optimized scanning sequence that reduces unnecessary transitions and lowers power consumption, while maintaining a simple overall circuit design that handles both fixed and variable scanning modes
3Use of energy by moving object
If scanning order is changed dynamically based on image data, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent implements dynamic scanning order adjustment with minimal increase in control circuit complexity. The gate driver control circuit incorporates mechanisms to detect image characteristics and automatically adjust scan sequences, achieving power optimization without requiring a completely complex redesign of the control architecture
Solution Approach 2:
The system optimizes power consumption by changing scan parameters dynamically while keeping the control circuit relatively simple. The patent demonstrates that parameter adjustment in the scanning order can be achieved through moderate circuit modifications rather than complete redesign, balancing power efficiency with circuit complexity
