Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for virtual and augmented reality require high display resolution and frame rates to produce natural three-dimensional images, which is resource-intensive and not efficiently achievable.
Innovation Solution
A display system comprising a pixel array, a shutter array, and a variable focus lens that outputs shuttered images based on depth information, allowing for the sequential presentation of images with varying focal lengths to create a natural 3D effect at lower frame rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high display resolution and high frame rate are used to reproduce natural 3D images, then image quality is improved, but resource consumption increases
Solution Approach 1:
The pixel array is divided into multiple areas, and the shutter array sequentially outputs shuttered images for each area. This segmentation allows the system to display high-resolution 3D content by presenting different portions of the image at different times, reducing the need for simultaneously high frame rates across the entire display
Solution Approach 2:
The variable focus lens dynamically changes its focal length based on depth information corresponding to different shuttered images. This dynamic adjustment enables natural 3D perception by matching focal length to depth, allowing high-quality 3D reproduction without requiring excessively high frame rates
2Productivity
If high display frame rate is used to output natural 3D images, then image quality is improved, but device complexity increases
Solution Approach 1:
The display frame is segmented into multiple shuttered images corresponding to different areas of the pixel array. By sequentially displaying these segmented frames rather than requiring a single high-frame-rate display, the system achieves natural 3D reproduction with reduced overall frame rate requirements
Solution Approach 2:
The shutter array acts as an intermediary between the display and the variable focus lens, selectively passing light from different areas at different times. This intermediary component enables the coordination between spatial segmentation and temporal sequencing, achieving natural 3D effects without requiring the display itself to operate at extremely high frame rates
