Light Field Display Tilting Units for Depth Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light field display technologies face limitations in displaying objects outside the original depth of field range due to restricted display pixel resources, leading to unclear images in certain depth sub-regions, which requires complex computations to adjust the display plane and focal length.
Innovation Solution
The method involves tilting display units with respect to the original plane of the display array based on the current depth of field range and depth distribution sub-regions to adjust the display image distance, allowing for improved clarity of objects outside the original depth of field range without complex computations, utilizing existing display pixel resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display units are tilted to improve clarity of objects outside the original depth of field range, then display quality is improved, but device complexity increases
Solution Approach 1:
The display array is divided into multiple independently controllable display units, each capable of being tilted at different angles. This segmentation allows selective adjustment of specific display units corresponding to objects in different depth sub-regions, improving display quality without requiring complex global adjustments.
Solution Approach 2:
The display units are designed with dynamic tilting capability, allowing their orientation to be adjusted in real-time based on the depth distribution of displayed objects. This dynamic adjustment enables the system to adapt to different depth of field requirements without physical reconfiguration.
2Manufacturing precision
If complex computations are performed to adjust display plane and focal length, then display quality is improved, but computing resources are consumed
Solution Approach 1:
Instead of performing complex computations to adjust the entire display plane and focal length, the system changes the orientation parameter of individual display units by tilting them. This parameter change approach simplifies the control process while achieving the same effect of improving display quality for objects outside the original depth of field range.
3Manufacturing precision
If display pixel resources are increased to improve clarity in all depth sub-regions, then display quality is improved, but device complexity increases
Solution Approach 1:
Rather than increasing pixel resources across the entire display array, the system applies tilting action to specific display units that correspond to objects outside the original depth of field range. This partial action approach maintains display quality improvement while avoiding the need for excessive pixel resources throughout the entire system.
