Vehicle Virtual Image Display Switching to Reduce Night Reflections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices with virtual image capabilities can cause visual fatigue and unwanted reflections, especially during night driving, as they require three-dimensional effects that may not be desirable for all situations.
Innovation Solution
A display device with a semi-transparent first surface creating a virtual image and a second visible surface, offering a second mode where all information is displayed on a two-dimensional plane without the three-dimensional lighting effects, allowing users to opt out of virtual image display when desired.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual image display mode is used with a semi-transparent display surface and display source, then the three-dimensional visual effect and information presentation capability are improved, but visual fatigue and unwanted reflections increase especially during night driving
Solution Approach 1:
The display device dynamically switches between two display modes: a first mode using a semi-transparent display surface with a display source to create a virtual three-dimensional image, and a second mode using an opaque display surface without the display source to show a two-dimensional image. This dynamic adaptation allows the system to adjust to different driving conditions (e.g., night driving vs. daytime) to reduce visual fatigue while maintaining versatile display capabilities.
Solution Approach 2:
The system changes the optical parameters of the display surface by switching between a semi-transparent state (first display surface) and an opaque state (second display surface). This parameter change allows the display device to eliminate unwanted reflections and visual fatigue during night driving by transitioning to the opaque mode, while maintaining the ability to provide three-dimensional visual effects when conditions are favorable.

3Object-affected harmful factors
If all information is displayed on a two-dimensional plane without three-dimensional effects, then visual fatigue is reduced and reflections are minimized, but the information presentation capability and ergonomics are worsened
Solution Approach 1:
The display device dynamically switches between two display modes: a first mode using a semi-transparent display surface with a display source to create a virtual three-dimensional image, and a second mode using an opaque display surface without the display source to show a two-dimensional image. This dynamic adaptation allows the system to adjust to different driving conditions (e.g., night driving vs. daytime) to reduce visual fatigue while maintaining versatile display capabilities.
Solution Approach 2:
The display device is designed to perform multiple functions through two display modes: the first mode provides enhanced three-dimensional visual presentation for better information comprehension during daytime, while the second mode provides a reflection-free two-dimensional display during night driving. This multi-functionality ensures the device adapts to different operational requirements, maintaining ease of operation across various conditions.
4Adaptability or versatility
If a first display surface and second display surface are used separately, then the versatility of information display is improved, but the device complexity is increased
Solution Approach 1:
The display device combines a first display surface (semi-transparent) and a second display surface (opaque) into a single integrated structure. The control unit coordinates both surfaces to display information in two different modes: a first mode using only the first display surface with a display source to create a virtual three-dimensional image, and a second mode using only the second display surface without the display source to show a two-dimensional image. This merging approach maintains versatility while managing device complexity through unified control.
