Solution Overview
Problem
Current 3D display technologies, especially glasses-free types, face limitations due to the lack of 3D film sources and require processing of 2D sources, which restricts their application range and user comfort.
Innovation Solution
A 3D display panel comprising a 2D display panel, an image separation device, a polarizing structure, an image isolation structure, a lens assembly, and a shielding component, which separates and processes 2D images into left-eye and right-eye images without gaps, using lenticular prism lenses and light-shielding layers to create parallax and 3D image pairs, allowing glasses-free 3D display without producing 3D film sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If glasses-free 3D display technology is implemented, then user comfort and application range are improved, but the technology requires processing of 2D sources and lacks 3D film sources which limits its effectiveness
Solution Approach 1:
The patent introduces an image separation device as an intermediary component that processes 2D film sources and separates them into left-eye and right-eye images. This mediator enables the system to work with standard 2D sources while producing 3D effects, bridging the gap between available 2D content and desired 3D output without requiring specialized 3D film sources
Solution Approach 2:
The patent replaces the need for mechanical 3D film sources with an optical processing system consisting of image separation devices, polarizing structures, and lens assemblies. This substitution allows the system to generate 3D effects through optical manipulation of 2D images rather than requiring physical 3D film inputs
2Reliability
If 3D film sources are produced and 2D sources are processed to achieve glasses-free 3D display, then 3D effect is achieved, but the process requires complex processing and image chips to support operations
Solution Approach 1:
The patent extracts the 3D processing functionality from complex image chips and software operations and implements it through dedicated optical components - image separation devices, polarizing structures, and lens assemblies. This extraction moves the complexity from electronic processing to optical hardware, simplifying the overall system architecture while maintaining reliable 3D effect generation
3Ease of operation
If lenticular prism lenses are used to separate pixels into adjacent image pixels, then glasses-free 3D display is enabled, but the structure becomes more complex with multiple components including polarizing structures and shielding components
Solution Approach 1:
The patent merges multiple functional components - image separation device, polarizing structure, and shielding component - into an integrated optical assembly that works together as a unified system. This merging reduces the number of separate elements the user must interact with while maintaining the complex functionality needed for glasses-free 3D display
