Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light field display technology sacrifices spatial resolution for flexible display properties, resulting in lower image quality compared to conventional displays, and existing methods struggle to meet diverse user requirements for different regions of an image.

Adjusting the display pixel density distribution of a light field display device to create non-uniform distributions, followed by sampling processing based on the actual locations of display pixels, allowing for differentiated spatial resolutions in different regions of the image, thereby optimizing the use of existing pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light field display technology uses uniform pixel distribution, then the display structure is simple, but the spatial resolution is low and image quality deteriorates
Solution Approach 1:
The patent applies local quality by transitioning from uniform pixel distribution to non-uniform pixel distribution, where different regions of the display have different pixel densities. Specifically, the center region has higher pixel density while peripheral regions have lower pixel density, optimizing spatial resolution where it matters most while reducing overall complexity
Solution Approach 2:
The patent changes the pixel density parameter from a constant uniform value to a variable non-uniform distribution pattern. This parameter change allows the system to achieve higher effective spatial resolution in critical viewing areas while maintaining manageable device complexity through controlled distribution patterns
2Adaptability or versatility
If light field display uses all pixels uniformly, then pixel utilization is complete, but the display cannot meet diverse user requirements for different image regions
Solution Approach 1:
The patent enables different regions of the display to have different pixel densities tailored to specific viewing requirements. The center region uses higher pixel density for critical content, while peripheral regions use lower density for less critical content, making the display adaptable to diverse viewing scenarios
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the pixel density distribution to be adjusted based on viewing conditions and content requirements, transitioning from a static uniform distribution to a dynamic non-uniform distribution that can be optimized for different use cases
3Adaptability or versatility
If light field display sacrifices spatial resolution for flexible display properties, then display flexibility is improved, but image quality deteriorates
Solution Approach 1:
The patent resolves this contradiction by applying different pixel densities to different regions - the center region maintains high pixel density for high image quality, while peripheral regions use lower pixel density to support flexible display properties, achieving both goals simultaneously in their respective zones

AI summary
The present application discloses a light field display control method and apparatus. The techniques of this disclosure provide a differentiated spatial resolution of different regions of a light field display image. The display pixel density distribution of the display of the light field display device is adjusted from original uniform distribution of display pixels to adjusted non-uniform distribution. The adjusted display pixels of the display includes non-uniform differentiated distribution. Sampling processing is then performed on a to-be-displayed light field image according to actual locations of the display pixels of the display, such that the light field image undergone the sampling processing corresponds to the actual locations of the display pixels of the display. The adjusted display displays the light field image that includes non-uniform differentiated distribution of pixels.
