Transparent Windscreen Head-Up Display Using Luminescent Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up displays for vehicles that project information directly onto the windscreen require coatings that reduce transparency, limiting their application to specific regions and hindering the ability to provide comprehensive information to drivers effectively.
Innovation Solution
A substantially transparent windscreen head-up display utilizing light-emitting particles or microstructures that allow for luminescent displays while maintaining visibility, enabling the projection of graphical information such as preferred driving distances based on vehicle speed, determined by monitoring and processing various sensor inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light is projected directly upon the windscreen to create a head-up display, then information can be displayed to the driver, but the transparency of the windscreen is significantly decreased
Solution Approach 1:
The windscreen is divided into a display region and a transparent region. The display region contains the head-up display information while the transparent region maintains full visibility. This spatial separation allows the display function to be localized without compromising the overall transparency of the windscreen.
2Adaptability or versatility
If a coating is applied to the windscreen to enable light projection, then head-up display functionality is achieved, but the application is restricted to limited regions
Solution Approach 1:
The windscreen is segmented into distinct functional zones: a display region with coating for head-up information and a transparent region without coating for unobstructed vision. This segmentation enables the head-up display to be implemented while preserving large areas of transparency, effectively resolving the conflict between display functionality and visible area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the display of critical driving information on a fully transparent windscreen, enhancing driver awareness without compromising visibility, and allowing for the projection of graphical data like preferred driving distances, thereby improving safety and operational efficiency.
Implementation Method 1
light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen
Data Source
AI summary
A substantially transparent windscreen head up display includes one of light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen. A method to display a graphic upon a substantially transparent windscreen head up display of a host vehicle describing a preferred driving distance for the host vehicle includes monitoring a speed of the host vehicle, determining a preferred driving distance for the host vehicle based upon the speed of the host vehicle, determining a graphic describing the preferred driving distance for display upon the substantially transparent windscreen head up display, and displaying the graphic upon the substantially transparent windscreen head up display.
