Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is designed to support both two-dimensional and three-dimensional displays, then the versatility and user experience are improved, but the device complexity increases
Solution Approach 1:
The grating layer is segmented into alternating light blocking portions and light transmitting portions, enabling different display modes through spatial segmentation of light paths
Solution Approach 2:
The liquid crystal layer provides dynamic control by rotating its optical axis under electric field control, allowing the display to switch between 2D and 3D modes through temporal changes in optical properties
2Illumination intensity
If a grating layer with alternating light blocking and transmitting portions is used, then the brightness and color fidelity are improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different regions of the grating layer have different optical properties (light blocking vs. light transmitting), with each region optimized for its specific function to enhance overall brightness and color fidelity
Solution Approach 2:
The grating structure introduces a spatial dimension pattern to the display layer, creating alternating regions that manipulate light in different ways to improve visual output
