Head-Up Display Projection Layout for Wider Field-of-View Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems have a limited range for image display in the user's field of view, depending on the positions of the user's eyes and the size of the display panel, which restricts the ability to project a wider image.
Innovation Solution
A head-up display system comprising a first projection module, a second projection module, and a first reflective optical element, where the first projection module projects a first image and the second projection module projects a second image, with the first reflective optical element reflecting parts of both images, allowing for a wider range of image display by adjusting the position and orientation of the display panels and using a parallax optical element to create a 3D image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single projection module is used, then the device complexity is reduced, but the image display range in the user's field of view is limited
Solution Approach 1:
The system divides the projection function into multiple independent projection modules (first projection module with first display panel, second projection module with second display panel). Each module projects images to different regions of the reflective optical element, thereby expanding the overall image display range in the user's field of view while maintaining manageable complexity through modular design
Solution Approach 2:
The system utilizes the vertical dimension of the reflective optical element by projecting images from multiple display panels at different positions and orientations. The first and second display panels are arranged to project onto different vertical regions of the reflective optical element, effectively expanding the display area in the vertical direction within the user's field of view
2Area of stationary object
If the display panel size is increased, then the image display range is expanded, but the position and orientation adjustment capability is reduced
Solution Approach 1:
Instead of using one large adjustable display panel, the system segments the display function into multiple smaller display panels (first display panel, second display panel). Each panel can be independently positioned and oriented to project onto different regions of the reflective optical element, providing both adequate display area and flexibility in positioning
Solution Approach 2:
The system employs adjustable mounting structures that enable dynamic positioning and orientation adjustment of each display panel relative to the reflective optical element. This allows the panels to be configured at optimal angles and positions to maximize image display range while maintaining adaptability to different viewing conditions
3Area of stationary object
If multiple projection modules are used, then the image display range is expanded, but the device complexity increases
Solution Approach 1:
The system merges multiple projection modules onto a single reflective optical element, combining their output in a unified optical path. The first and second projection modules project onto different regions of the same reflective optical element, which then reflects both images to the user's field of view, achieving expanded display range while consolidating the optical architecture
Solution Approach 2:
The reflective optical element serves multiple functions: it reflects images from both the first and second projection modules, and can be positioned to direct these images to different regions of the user's field of view. This multi-functional component reduces overall system complexity by consolidating reflection and positioning functions
