Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate driving systems are used to display the same images on both panels, then the display reliability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges two separate driving systems into one shared driving system that controls both liquid crystal panels. The first data driver and second data driver are integrated into a single driving system, reducing device complexity and cost while maintaining display functionality through shared control resources.
Solution Approach 2:
The driving system is designed with universal functionality to control both the first liquid crystal panel and the second liquid crystal panel. The data drivers can drive multiple panels simultaneously, making the driving system multi-functional and adaptable to different display configurations.
2Manufacturing precision
If two separate driving systems are used for each panel, then the display control precision is improved, but the weight and thickness increase
Solution Approach 1:
The patent combines two separate driving systems into one shared driving system, directly reducing the overall weight of the device. By eliminating redundant driving components for the second panel, the total weight is reduced while maintaining display control precision through the shared driving architecture.
3Manufacturing precision
If two separate driving systems are used, then the display control precision is improved, but the device thickness increases
Solution Approach 1:
The patent merges two separate driving systems into one shared driving system, reducing the overall thickness of the device. By consolidating the driving components and eliminating redundant layers for the second panel, the device achieves a thinner profile while maintaining precise display control.
4Adaptability or versatility
If multiple signal input devices and sources are used, then the display versatility is improved, but the device complexity increases
Solution Approach 1:
The driving system is designed with universal functionality to handle multiple signal input devices and sources. The data drivers can accept signals from various sources and distribute them to both panels, providing versatility without requiring separate dedicated input devices for each panel.
