VR Device Lens Spacing Regulation for Display Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VR devices face issues with displaying content fully on the visible area of the display screen, leading to blurry or invisible edges due to the size of the rendered image being larger than the visible area.
Innovation Solution
A regulation and control method for VR devices that adjusts the lens spacing and field of view to match the visible area on the display screen, using a sliding rheostat device to dynamically adjust the lens spacing and a processor to calculate the corresponding field of view and visible area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens spacing is adjusted to accommodate myopic users, then the adaptability of the VR device is improved, but the displayed content cannot be fully presented on the visible area, causing blurry or invisible edges
Solution Approach 1:
The patent implements dynamic adjustment of lens spacing through a sliding mechanism that allows the lens to move along an optical axis. This dynamic structure enables the VR device to adapt to different myopic degrees by adjusting the lens spacing, while simultaneously maintaining proper alignment between the display area and visible area through coordinated control of the rendering scene field of view and display screen visible area
Solution Approach 2:
The patent changes the lens spacing parameter to accommodate different myopic users. By adjusting this physical parameter, the device achieves adaptability for various users. Concurrently, the patent adjusts the field of view parameter of the rendering scene and the visible area parameter of the display screen to match the adjusted lens spacing, ensuring that the display area remains completely located within the visible area and preventing blurry or invisible edges
2Adaptability or versatility
If the rendered image size is increased to provide better viewing, then the field of view is improved, but the image exceeds the visible area, resulting in poor display performance
Solution Approach 1:
The patent establishes a feedback control mechanism where the lens spacing adjustment triggers corresponding adjustments in the rendering scene field of view and display screen visible area. The system monitors the lens spacing state and automatically coordinates the field of view and visible area parameters to ensure the display area remains completely within the visible area, preventing blurry or invisible edges and maintaining reliable display performance
Solution Approach 2:
The patent implements dynamic coordination between lens spacing, field of view, and visible area parameters. When the lens spacing is adjusted for myopic users, the system dynamically adjusts the rendering scene field of view and display screen visible area accordingly, ensuring that the display area remains completely located within the visible area while maintaining optimal field of view for the user
