Vehicle Display Surfaces for Switching Off 3D Virtual Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices with virtual image capabilities can cause visual fatigue and unwanted reflections, especially during nighttime driving, as they often rely on three-dimensional effects that may not be desirable for all situations.
Innovation Solution
A vehicle display device with discrete semi-transparent and digital display surfaces, allowing for a second mode where all information is displayed on a two-dimensional plane without the display source's illumination, eliminating three-dimensional effects and reflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display source with illumination is used to create a virtual image on a semi-transparent display surface, then three-dimensional visual effects are achieved, but visual fatigue and unwanted reflections increase especially during nighttime driving
Solution Approach 1:
The display device dynamically switches between two display modes: a first mode using a display source with illumination to create a virtual image on a semi-transparent display surface for three-dimensional visual effects, and a second mode using a display surface without illumination to provide a two-dimensional flat display. This dynamic adaptation allows the system to adjust to different driving conditions, particularly reducing visual fatigue during nighttime driving by eliminating unwanted reflections when the display source is not illuminated.
2Loss of information
If a display source is illuminated to produce a virtual image, then information is displayed with three-dimensional effects, but reflections and visual fatigue are caused
Solution Approach 1:
The display device is segmented into two distinct display surfaces: a first display surface that is semi-transparent and designed to create a virtual image obtained by reflection of an image produced by a display source, and a second display surface that is visible through the first display surface. This segmentation allows the system to display all information on the second display surface in a two-dimensional plane when the display source is switched off, thereby eliminating reflections while maintaining complete information display.
3Adaptability or versatility
If a semi-transparent display surface is used to create virtual images, then three-dimensional visual effects are achieved, but the display complexity increases
Solution Approach 1:
The display device integrates multiple functions into a single system: it can operate in a first display mode where the display source is illuminated to create a virtual image on the semi-transparent first display surface for three-dimensional effects, and in a second display mode where the display source is switched off and all information is displayed on the second display surface in a two-dimensional plane. This multi-functionality allows the system to adapt to different user needs and driving conditions without requiring separate display devices.
