Active Vehicle Window Display for Augmented Reality Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle window glass is passive and underutilized for presenting information, lacking the capability to display video, images, or text while maintaining transparency or opacity as needed.
Innovation Solution
Implementing active vehicle window glass that can present video, images, or text by using transparent or flexible OLED displays, and integrating cameras and processors to superimpose images onto the natural view, allowing for augmented reality experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If passive vehicle window glass is used, then the window maintains transparency and structural simplicity, but the window cannot present information such as video, images, or text
Solution Approach 1:
The patent merges the window glass structure with an active display system by integrating transparent OLED pixels, control circuits, and power management components directly into the window assembly. This combination enables the window to function both as a transparent barrier and as an information display device, resolving the contradiction between maintaining transparency and enabling information presentation.
Solution Approach 2:
The window is designed to perform multiple functions: it serves as a transparent protective barrier, an information display interface, and a controllable opaque screen when needed. The ability to switch between transparent and opaque states while presenting various types of information (video, images, text) makes the window a multi-functional component that addresses the information presentation need without sacrificing other window functions.
2Adaptability or versatility
If active display components are integrated into the window, then the window can present video, images, and text, but the manufacturing complexity and cost increase
Solution Approach 1:
The display surface is divided into individual controllable pixels or pixel regions, each capable of independent control. This segmentation allows for modular manufacturing approaches where display modules can be produced separately and then integrated into the window structure, reducing overall manufacturing complexity while maintaining high adaptability for different information display requirements.
Solution Approach 2:
The window's optical properties (transparency, opacity, brightness) are made dynamically changeable through electronic control of the OLED pixels. This parameter change capability allows the window to adapt its display characteristics based on viewing conditions, ambient light, and information type, providing versatility without requiring multiple physical window components.
3Illumination intensity
If the window switches between transparent and opaque states, then information can be displayed, but control and power management complexity increases
Solution Approach 1:
The window incorporates integrated power management circuits and control systems that automatically regulate power distribution to different pixel regions based on display requirements. The system can autonomously adjust transparency and opacity states without requiring complex external control mechanisms, reducing overall system complexity while maintaining effective illumination control for optimal display visibility.

AI summary
A camera on a vehicle captures an image of the surroundings, and the image is presented in a window of the vehicle that is established by a transparent display such as an OLED display or transparent LCD display. The image from the camera is presented on the display according to the angle of the camera with respect to the vehicle, such that an occupant of the vehicle sees the image on the window substantially in the same relative location with respect to the surroundings as the occupant would see looking at the objects in the image through the window. In other embodiments images from a database are presented on the window superimposed onto background objects seen through the window.
