Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional liquid crystal displays are used in AR technology with multiple optical film layers, then the display structure can be achieved, but interference light is generated at large angles affecting display quality
Solution Approach 1:
The patent extracts and removes the problematic optical film layers that cause interference light in conventional AR displays. By eliminating these layers and replacing them with the micro-lens array structure, the source of interference is removed while maintaining the necessary display functionality.
Solution Approach 2:
The patent changes the optical parameters by introducing micro-lens structures with specific refractive indices and curvature radii. These parameter changes enable the micro-lenses to converge large-angle light into smaller angles, fundamentally altering how light propagates through the display structure.
2Ease of manufacture
If optical film layers are added to achieve AR display structure, then the display can be formed, but display quality deteriorates due to interference light
Solution Approach 1:
The patent converts the harmful large-angle light that causes interference into a beneficial resource. By using micro-lens structures, the large-angle light is converged and redirected, transforming what was previously harmful interference into useful light that contributes to display quality.
3Object-affected harmful factors
If micro-lens array is introduced to converge light, then interference light is reduced, but device complexity increases
Solution Approach 1:
The patent merges the optical layer with either the array substrate or color filter substrate, integrating the micro-lens array structure into existing display components. This consolidation reduces the number of separate layers and simplifies the overall device structure while maintaining the light-converging functionality.
4Manufacturing precision
If optical layer is added to converge light, then display quality is improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the optical layer directly into the array substrate or color filter substrate manufacturing process. By forming the micro-lens array structure during existing manufacturing steps rather than as a separate addition, the patent avoids increasing manufacturing complexity while achieving improved display quality.
