Naked-Eye 3D Display Refraction Structures for Multi-Angle Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing naked-eye 3D display technologies are limited by the restriction of two specific viewing areas, which severely limits user mobility and viewing freedom, as users must be positioned exactly in these areas to experience stereoscopic effects.
Innovation Solution
A display device with multiple sub-pixels arranged in an array, each corresponding to a specific viewing area, and equipped with refraction structures that refract light from sub-pixels to their respective viewing areas, allowing for more than two viewing areas and enhanced user mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a grating is set outside the display panel to refract light to two viewing areas, then stereoscopic display is achieved, but the viewing angle and position are greatly restricted
Solution Approach 1:
The patent divides the display area into multiple independent display units, each with its own refraction structure. Each display unit corresponds to a specific viewing area, creating multiple discrete viewing zones rather than a single restricted area. This segmentation allows different users to view from different positions simultaneously, resolving the contradiction between maintaining stereoscopic effect and improving viewing freedom.
Solution Approach 2:
The patent extends the viewing solution from a single-plane two-area configuration to a multi-dimensional array of display units with corresponding refraction structures. By arranging display units and refraction structures in spatial arrays with specific geometric relationships, the system creates multiple viewing areas in different spatial positions, transforming the viewing experience from restricted 2D to expanded 3D space.
2Device complexity
If only two viewing areas are formed, then the grating structure is simple, but user mobility and viewing freedom are severely limited
Solution Approach 1:
The patent segments the display system into multiple independent display units, each with its own refraction structure. This modular segmentation allows the system to provide multiple viewing areas while maintaining the simplicity of individual unit structures. Each unit remains relatively simple, but the collective array provides enhanced viewing freedom without requiring complex individual components.
Solution Approach 2:
The patent creates a dynamic viewing experience by forming multiple viewing areas that can accommodate user movement. The array of display units and refraction structures is configured to provide viewing coverage across different positions, allowing users to move freely within the viewing zone while maintaining access to stereoscopic display functionality.
3Adaptability or versatility
If multiple sub-pixels are arranged in an array with refraction structures, then multiple viewing areas are enabled, but the device complexity increases
Solution Approach 1:
The patent divides the display into multiple display units, each comprising sub-pixels and a corresponding refraction structure. This segmentation strategy manages complexity by creating repeatable modular units rather than a monolithic complex structure. Each unit can be independently designed and manufactured, then assembled into arrays that provide multiple viewing areas, balancing versatility with manageable complexity.
Solution Approach 2:
The patent designs display units with universal characteristics where each unit can serve multiple viewing functions. The refraction structures are configured to direct light to specific viewing areas based on their position in the array, allowing the same basic unit design to fulfill different viewing roles depending on its location, thereby reducing overall system complexity while maintaining versatility.
