Light Field Display Pixel Density Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light field display technologies sacrifice spatial resolution to achieve flexible display effects, leading to lower image quality and inefficient pixel utilization, as they often require uniform pixel density across all image regions, which does not align with users' varying levels of interest in different parts of an image.
Innovation Solution
A light field display control method that samples source images based on interest level distribution information and adjusts display pixel density distribution accordingly, allowing for differential spatial resolution in different regions of the image, thereby optimizing pixel usage and improving display efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform pixel density is used across all image regions in light field display, then flexible display effects are achieved, but spatial resolution is sacrificed and image quality deteriorates
Solution Approach 1:
The patent applies local quality by dividing the display area into multiple regions with different pixel densities. High-density regions are allocated to areas requiring fine detail (such as central viewing zones), while low-density regions are used for peripheral areas. This non-uniform pixel distribution maintains flexible light field display effects while preserving spatial resolution where it matters most, resolving the contradiction between adaptability and manufacturing precision.
2Device complexity
If uniform pixel density is used across all image regions, then hardware structure simplicity is maintained, but pixel utilization efficiency decreases
Solution Approach 1:
The patent implements dynamic pixel density adjustment where the display system can adaptively modify pixel activation patterns based on content requirements and viewing conditions. By dynamically controlling which pixels are active in different regions, the system improves pixel utilization efficiency without requiring permanent hardware modifications, thus maintaining hardware simplicity while enhancing productivity.
3Manufacturing precision
If high spatial resolution is maintained uniformly across the display, then image quality is preserved, but pixel resources are wasted in low-interest regions
Solution Approach 1:
The patent applies local quality by allocating high pixel density only to regions of interest where high spatial resolution is necessary for image quality, while using lower pixel density in regions where users are less likely to focus attention. This selective resource allocation maintains perceived image quality while significantly reducing the total number of pixels required, thereby reducing energy consumption and eliminating pixel resource waste.
