Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a substrate is used to support the liquid crystal layer, then the liquid crystal layer can be supported, but the thickness of the three-dimensional display increases
Solution Approach 1:
The patent removes the substrate from the liquid crystal display structure by using a liquid crystal layer directly on the color filter layer. This extraction of the substrate eliminates the thickness contribution while maintaining the support function through the color filter layer's structural integrity.
Solution Approach 2:
The color filter layer serves multiple functions: it acts as both the optical filter for color selection and the structural support for the liquid crystal layer. This multi-functionality eliminates the need for a separate substrate, reducing overall thickness while maintaining support capability.
2Manufacturing precision
If a substrate with zero phase retardation is used, then display quality is maintained, but manufacturing cost increases
Solution Approach 1:
The patent employs a inexpensive color filter layer made from organic compounds that can be deposited using standard semiconductor manufacturing techniques. This replaceable, cost-effective layer provides the necessary optical functions without requiring expensive zero-phase-retardation substrates.
Solution Approach 2:
The patent utilizes the inherent phase retardation properties of the color filter layer material itself, changing the optical parameter from requiring external zero-phase-retardation substrate to utilizing the natural optical properties of the color filter layer material, thereby reducing manufacturing costs while maintaining display quality.
