Solution Overview
Problem
Naked-eye 3D display systems face issues with crosstalk and reduced resolution due to the physical propagation of light, leading to restricted depth of field and degraded image quality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a micro-lens array is used to refract interlaced image in different directions to provide 3D image, then 3D image can be viewed by naked eyes without glasses, but crosstalk effect occurs in adjacent pixels leading to degradation in resolution
Solution Approach 1:
The patent divides the display panel into multiple virtual pixel regions corresponding to different depth layers. By segmenting the pixel allocation based on depth information, the system assigns specific pixels to specific depth layers, reducing crosstalk between adjacent pixels displaying different depth information. This segmentation approach maintains naked eye 3D viewing while improving resolution by preventing overlapping of crosstalk effects.
Solution Approach 2:
The patent applies different pixel allocation strategies to different spatial locations and depth layers. Each depth layer has its own designated pixel regions, allowing the system to optimize pixel usage locally for each depth plane. This local quality approach ensures that pixels at different locations serve specific depth functions, reducing crosstalk while maintaining overall image quality and naked eye 3D capability.
2Ease of operation
If multi-view image is separated through refraction of lens, then 3D image can be displayed, but ray of light is diffused leading to interference in adjacent pixels and degradation in resolution
Solution Approach 1:
The patent segments the light propagation paths by assigning specific pixels to specific depth layers. Each depth layer's light rays are directed to designated regions, preventing diffusion-induced interference with adjacent pixels. This segmentation of light paths maintains 3D image display capability while resolving the resolution degradation caused by light diffusion.
Solution Approach 2:
The patent introduces a virtual pixel region assignment mechanism as an intermediary between the lens array and the final image display. This intermediary layer organizes pixel allocation according to depth layers, mediating the refraction process to prevent harmful interference while preserving the 3D display function.
3Device complexity
If regular pixels are used for 3D image display, then simple pixel arrangement is achieved, but crosstalk causes overlapping of 3D images and resolution degradation
Solution Approach 1:
The patent segments the regular pixel array into virtual pixel regions assigned to different depth layers. This segmentation transforms the simple but problematic regular pixel arrangement into a structured depth-layered allocation, reducing crosstalk while maintaining manufacturing simplicity. The segmentation is achieved through software-controlled pixel assignment rather than physical pixel restructuring.
Solution Approach 2:
The patent adds a depth layer dimension to the traditional 2D pixel arrangement. By organizing pixels into multiple depth layers along the Z-axis, the system transforms the flat pixel grid into a three-dimensional pixel space, enabling depth-aware pixel allocation that reduces crosstalk while maintaining simple regular pixel physics.
