Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed layout period is used for pixel units, then the device structure is simple, but crosstalk occurs between adjacent layout units at different viewing distances and angles
Solution Approach 1:
The patent applies dynamics by making the layout period variable instead of fixed. The controller dynamically adjusts the layout period of pixel units based on the viewing distance and angle, allowing the system to adapt to different observation conditions and eliminate crosstalk that occurs with fixed periodic arrangements.
Solution Approach 2:
The patent changes the parameter of layout period from a constant value to a variable that depends on viewing distance and angle. By adjusting this parameter according to observation conditions, the system maintains optimal display quality across different viewing scenarios without requiring complex structural modifications.
2Reliability
If the layout period is adjusted for different viewing conditions, then crosstalk is reduced, but the control system becomes more complex
Solution Approach 1:
The system implements self-service by automatically calculating and adjusting the layout period based on detected viewing conditions. The controller receives input about viewing distance and angle, then autonomously determines the appropriate layout period without requiring manual intervention, simplifying operation while maintaining effective crosstalk elimination.
Solution Approach 2:
The patent employs feedback mechanisms where the controller continuously monitors viewing conditions and adjusts the layout period accordingly. This closed-loop control ensures that the display adapts to changing observation parameters, maintaining optimal performance while the system handles the complexity of adjustments automatically.
3Manufacturing precision
If pixel units are arranged with small spacing to increase resolution, then display detail is improved, but crosstalk between adjacent units increases
Solution Approach 1:
The patent applies local quality by making the layout period position-dependent rather than uniform throughout the display. Different regions of the pixel array use different layout periods optimized for their specific viewing characteristics, allowing high resolution in critical areas while maintaining adequate spacing to prevent crosstalk where needed.
