Rollable 3D Vehicle Display With Eye-Tracked Adaptive Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle displays, especially 2D displays, lack effective integration with real-world spatial contexts and provide poor interaction with the surrounding environment, particularly in terms of depth of view, and existing 3D holographic displays are costly and inefficient.
Innovation Solution
A virtual 3D display system featuring a flexible, rollable, and bendable substrate with an eye tracker and touch/gesture sensors, which adjusts 3D effects based on occupant eye location and movement, and reconfigures itself for different vehicle applications or driving conditions, using tracks on the cabin's floor and ceiling for deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 3D holographic displays are used, then depth of view and spatial context are improved, but cost and device complexity increase
Solution Approach 1:
The patent uses a flexible display that can be positioned at various locations and angles to create virtual 3D images, copying the visual information from the source display to multiple virtual viewing positions. This approach achieves 3D depth of view without the complexity of true holographic technology, as the flexible display acts as a movable copy that can be deployed to different spatial configurations.
Solution Approach 2:
The flexible display is designed to be dynamically reconfigurable, allowing it to change position, orientation, and shape within the vehicle cabin. This dynamic capability enables the system to adapt to different viewing requirements and spatial constraints, providing 3D depth of view through movement rather than through complex static holographic optics.
2Illumination intensity
If 3D holographic displays are used, then depth of view is improved, but cost increases
Solution Approach 1:
Instead of manufacturing expensive holographic display systems, the patent uses a flexible display that can be manufactured using standard flexible display technologies. The 3D effect is achieved through the flexible display's ability to be positioned at various locations, creating virtual images without requiring complex holographic manufacturing processes.
Solution Approach 2:
The system achieves 3D depth of view by changing the physical parameters of the flexible display (position, orientation, curvature) rather than through complex optical parameters. This approach allows standard flexible display manufacturing to be used, avoiding the high costs associated with holographic display manufacturing.
3Device complexity
If a fixed display is used, then device complexity is reduced, but adaptability to different vehicle applications and driving conditions decreases
Solution Approach 1:
The flexible display is designed to be dynamically reconfigurable, allowing it to change position, orientation, and shape in response to different vehicle applications and driving conditions. This dynamic capability provides adaptability without requiring multiple fixed display systems, maintaining relatively simple device complexity while achieving high versatility.
Solution Approach 2:
The flexible display serves multiple functions across different vehicle applications (manual driving, autonomous driving, passenger entertainment, driver assistance). By using a single flexible display that can be reconfigured for different purposes, the system achieves multi-functionality without the complexity of having separate dedicated displays for each function.
