Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat panel autostereoscopic display is used, then the manufacturing process is simple, but three-dimensional crosstalk increases and ghosting becomes obvious when users look at the sides of the display
Solution Approach 1:
The patent applies curvature to the display panel, transforming it from a flat surface to a curved surface. This curvature modifies the optical path and viewing geometry, thereby reducing three-dimensional crosstalk and ghosting effects when users view from angles, while still maintaining the autostereoscopic display functionality.
2Ease of manufacture
If a flat panel autostereoscopic display is used, then the manufacturing process is simple, but two-dimensional resolution is reduced due to geometric optics of the stereoscopic lenticular mirror
Solution Approach 1:
By curving the display panel, the patent modifies the optical geometry to improve two-dimensional resolution. The curvature compensates for the geometric optics limitations of the lenticular mirror, allowing users to achieve native two-dimensional display resolution while maintaining the autostereoscopic three-dimensional viewing capability.
3Object-affected harmful factors
If a curved autostereoscopic display is used to reduce three-dimensional crosstalk, then ghosting in three-dimensional images is reduced, but the design of curvature radius becomes complex and manufacturing difficulty increases
Solution Approach 1:
The patent provides specific parameter ranges and calculation methods for determining the optimal curvature radius. By establishing concrete design guidelines and formulas, the patent simplifies the curvature radius design process and makes it more accessible for manufacturing while achieving the desired reduction in ghosting.
4Ease of manufacture
If an inappropriate curvature radius is used, then manufacturing is easier, but three-dimensional crosstalk increases and image quality deteriorates
Solution Approach 1:
The patent establishes specific parameter ranges and calculation methods for determining the optimal curvature radius. By providing concrete design guidelines, the patent enables manufacturers to achieve both ease of manufacture and high image quality by following the prescribed parameter specifications.
