Ultra-Wide Head-Up Display Dynamic Information Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-display head-up systems for vehicles are not designed for flat and elongated areas, leading to inefficient use of the statutorily acceptable display region and limited functionality, particularly in complex driving conditions where multiple types of information need to be displayed simultaneously.
Innovation Solution
An ultra-wide head-up display system that includes a display apparatus and a control apparatus, dynamically switching information types and adjusting display positions based on vehicle usage status, utilizing a display region with a width-to-length ratio greater than or equal to 3, and forming outer frames by regions not displaying images, to provide an augmented reality experience with improved image quality and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a common display ratio (16:9 or 4:3) is applied to the statutorily acceptable elongated region, then the display device can be manufactured with standard specifications, but only a portion of the elongated region can be utilized for display
Solution Approach 1:
The display region is segmented into multiple independent display areas, each with its own outer frame. The control apparatus divides the ultra-wide display region into multiple zones that can independently display different types of information (vehicle status, navigation, entertainment, etc.), allowing full utilization of the elongated region while maintaining manageable complexity through modular information presentation
Solution Approach 2:
The system transitions from traditional single-display or multi-display configurations to an ultra-wide single-display configuration with aspect ratio ≥3:1. This dimensional change in the display region allows multiple information types to be presented simultaneously across the extended horizontal space, maximizing area utilization without requiring multiple separate display devices
2Device complexity
If a single-display HUD is used, then the device structure is simple, but it cannot display multiple types of driving information simultaneously in complex driving conditions
Solution Approach 1:
The control apparatus dynamically adjusts the display content, outer frame configurations, and information types based on real-time driving conditions and vehicle usage status. The system can switch between different display modes (ultra-wide image, augmented reality image, or combination) and adaptively allocate display regions to different information types, providing versatility while maintaining a single physical display device
Solution Approach 2:
The single display apparatus is designed to perform multiple functions by displaying various types of information simultaneously across different regions. The ultra-wide display region can present navigation, vehicle status, entertainment, safety warnings, and augmented reality overlays all at once, making one device universally capable of handling diverse driving information needs
3Area of stationary object
If the display region is expanded to ultra-wide aspect ratio, then more information can be displayed, but the image quality and pixel density may be compromised
Solution Approach 1:
The control apparatus applies different image processing parameters and pixel density allocations to different regions of the ultra-wide display. Critical information areas receive higher effective resolution through selective scaling and rendering optimization, while less critical areas use appropriate lower densities, maintaining overall image quality across the expanded display region
Solution Approach 2:
The system dynamically adjusts display parameters including pixel density, aspect ratio, and rendering resolution based on the selected display mode (ultra-wide vs. augmented reality). The control apparatus modifies these parameters in real-time to optimize image quality for the current usage status, ensuring high precision is maintained where needed while accommodating the ultra-wide format
