Multi-Screen Display with Light Transmission for Stereo Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices can only clearly show an object at a single fixation point, failing to provide a clear stereo image of objects at different depths, leading to a limited viewing experience and potential dizziness.
Innovation Solution
A display device with multiple screens and a light transmission portion that adjusts image plane distances and resolutions based on eye tracking data to create a stereo image effect by positioning the fixation point on one screen with higher resolution and surrounding areas with lower resolution, using convex lenses and transflective mirrors to direct image light to the eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display screen is used to show objects at different depths, then the device complexity is low, but the ability to present clear stereo images at multiple depths is insufficient
Solution Approach 1:
The patent divides a single display screen into multiple virtual image planes at different depths. By using a light transmission portion with optical elements (convex lenses and transflective mirrors), the system segments the display content into multiple depth layers that can be independently focused, allowing clear presentation of stereo images at multiple depths while maintaining a single physical display device.
Solution Approach 2:
The patent adds the depth dimension to the traditional two-dimensional display by creating multiple image planes at different distances from the display screen. Through optical manipulation, objects are rendered at various depths along the optical axis, transforming the display from a flat 2D surface to a multi-layered 3D spatial presentation.
2Measurement precision
If multiple display screens are used to show objects at different depths, then the stereo image clarity is improved, but the device complexity increases
Solution Approach 1:
The patent makes a single display screen perform multiple functions by simultaneously presenting multiple image planes at different depths. The light transmission portion enables one display screen to serve as multiple virtual displays at various depths, achieving the stereo image clarity of multiple screens without the physical complexity of actually using multiple display devices.
Solution Approach 2:
The light transmission portion acts as an intermediary between the single display screen and the viewer's eye. This intermediary component with convex lenses and transflective mirrors creates multiple virtual image planes from a single physical screen, enabling clear stereo imaging without requiring multiple physical display screens.
3Ease of operation
If high display resolution is applied to the entire image plane, then the overall image quality is high, but the ability to focus attention on the fixation point is reduced
Solution Approach 1:
The patent applies different display resolutions to different regions of the image plane based on the fixation point position. The area around the fixation point maintains high display resolution for clear focus, while surrounding areas use lower resolution. This local quality differentiation optimizes visual attention on the fixation point while reducing overall system complexity.
4Adaptability or versatility
If the light beam diameter is fixed, then the optical system is simple, but the adaptability to different pupil sizes is poor
Solution Approach 1:
The patent introduces a light beam adjuster that can dynamically change the light beam diameter to match different pupil sizes. This dynamic adjustment capability allows the optical system to adapt to various viewing conditions and user characteristics without requiring multiple fixed optical configurations, maintaining versatility while controlling complexity.

Function Achieved in This Case
This solution enables clear perception of stereo images in different depths, reducing visual fatigue and improving the viewing experience by aligning image planes with the eye's foveal region and blurring surrounding areas, thus enhancing the realism of the stereo effect.
