Auxiliary Shaded Layer for Transparent Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent display devices used in XR technology struggle to effectively separate virtual objects from real-world backgrounds, leading to degraded visibility and realism of virtual objects due to their transparent nature, which hinders the adoption and popularity of XR technologies.
Innovation Solution
A wearable display device incorporating a transparent display unit and an auxiliary transparent display unit that generates a shaded area matching the size and position of the virtual object, preventing light from the real-world background from penetrating the virtual object, thereby enhancing its visibility and realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent display device is used to display virtual objects, then the device allows users to see through the display to the real-world background, but the virtual objects overlap with the real-world background reducing visibility and realism
Solution Approach 1:
The display system is segmented into multiple independent display layers. The first transparent display layer displays the virtual object, while the second transparent display layer displays the real-world background. This segmentation allows independent control of each layer's transparency and brightness, enabling the virtual object to be clearly distinguished from the background without sacrificing the transparent display capability.
Solution Approach 2:
The solution transitions from a single-layer display to a multi-layer display architecture. By adding the dimension of depth (multiple layers), the system can separate virtual objects from the real-world background in the vertical dimension, allowing users to perceive depth and improve visibility while maintaining transparency.
2Adaptability or versatility
If a transparent display device is used to display virtual objects, then the device maintains transparency to show real-world backgrounds, but the virtual objects lack realism due to overlap with background elements
Solution Approach 1:
Different regions of the display system are assigned different quality characteristics. The first display layer is optimized for displaying virtual objects with appropriate brightness and transparency, while the second display layer is optimized for displaying the real-world background. This local quality differentiation ensures that virtual objects appear realistic and distinct from the background while maintaining overall transparent display functionality.
Solution Approach 2:
The display system uses a composite structure combining multiple transparent display layers with different optical properties. Each layer can be independently tuned to have specific transparency, brightness, and contrast characteristics, creating a composite display system that simultaneously achieves high virtual object realism and maintains transparent background visibility.
3Device complexity
If a single transparent display layer is used, then the device structure remains simple, but the visibility and separation of virtual objects from the background deteriorates
Solution Approach 1:
The display system is divided into multiple independent display layers, each responsible for displaying specific content. The first layer displays virtual objects while the second layer displays the real-world background. This segmentation improves virtual object-background separation by allowing independent optimization of each layer's display parameters without increasing overall structural complexity significantly.
Solution Approach 2:
The system transitions from a single-layer to a multi-layer architecture, adding the vertical dimension to the display structure. This dimensional change enables better separation of virtual objects from the background by placing them on different layers, improving visibility while the modular design keeps the structural complexity manageable.

AI summary
The virtual object visibility improvement device includes an auxiliary transparent display unit that displays a shaded area matching the size of the virtual object behind the transparent display unit that displays the virtual object, and when viewed by the human eye, the virtual object is displayed on the real space actual object in the transparent display unit, and the light of the real space actual object is not transmitted to the virtual object due to the shaded area, so that the virtual object is not visible to be overlapped with the real space actual object.
