Display Optics for Peripheral Visual Field Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for improving human visual perception, such as those disclosed in Patent Literatures 1 and 2, do not adequately enhance the visibility of display images, particularly in peripheral visual fields.
Innovation Solution
A display apparatus that radiates light to regions outside the central visual field of the retina, including peripheral and binocular visual fields, with varying resolutions and content complexity to improve visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is radiated only to the central visual field (first region), then high resolution can be achieved in the central area, but visibility in peripheral visual fields remains insufficient
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics for different retinal regions. The central visual field (first region) receives high-resolution light radiation, while the peripheral visual field (second region) receives light radiation with appropriately adjusted resolution parameters. This matches the natural visual acuity distribution where the fovea centralis requires high resolution but peripheral regions function adequately with lower resolution, thereby improving overall visibility without wasting resources on uniformly high resolution across all regions.
2Illumination intensity
If light is radiated to extend beyond the central visual field to peripheral regions, then visibility in extended areas is improved, but the complexity of the display system increases
Solution Approach 1:
The patent segments the visual field into distinct regions: the central visual field (first region) corresponding to the fovea centralis, and the peripheral visual field (second region) corresponding to areas outside the fovea. The irradiation system is configured to radiate light to both regions with different parameters - high resolution for the first region and adjusted resolution for the second region. This segmentation approach simplifies the overall system design by matching display characteristics to the functional requirements of each retinal region rather than attempting uniform high-resolution coverage.
3Manufacturing precision
If high resolution is provided across the entire visual field including peripheral areas, then overall image clarity improves, but the energy consumption and system resources increase significantly
Solution Approach 1:
The patent changes the resolution parameter based on the target retinal region. The irradiation system radiates light with high resolution parameters to the first region (central visual field/fovea centralis) and with different, appropriately reduced resolution parameters to the second region (peripheral visual field). This parameter adaptation reduces the total number of light radiation operations required while maintaining perceptually adequate quality across the entire visual field, thereby reducing energy consumption and system resource utilization.
