Vehicle Display Color Coordination for Navigation Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices face challenges in maintaining visibility and balance of information display, particularly when navigation and meter data are presented together, as the navigation display can overpower warning indicators and hinder the driver's attention to critical information due to color conflicts and cumbersome operation.
Innovation Solution
A display device with dynamically adjustable areas for vehicle travel information, using a color changing unit to maintain color balance and emphasize critical information by converting display colors to enhance visibility and recognition, implemented through a program that can be easily updated, allowing for flexible design and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If navigation display is made bright and large to improve visibility, then navigation information becomes more visible, but warning indicators and critical meter information become less recognizable due to color conflicts
Solution Approach 1:
The patent applies local quality by assigning different color characteristics to different display regions. The navigation display area uses one set of color properties while the meter and warning indicator areas use another set, allowing each region to optimize its visibility without interfering with others. This is achieved through separate color setting mechanisms for different display zones.
Solution Approach 2:
The display is segmented into distinct functional areas (navigation display area and meter/warning area) with independent color control. This segmentation allows the navigation display to be made bright and large while simultaneously maintaining the recognizability of warning indicators through separate color management for each segment.
2Illumination intensity
If specific meter is displayed in scale-up mode or with eye-catching color to enhance visibility, then that specific information becomes more visible, but overall display balance is degraded
Solution Approach 1:
The patent implements dynamic color adjustment where the display system automatically adapts color settings based on the current display state. When certain meters are enlarged or emphasized, the system dynamically adjusts the colors of surrounding elements to maintain overall balance, preventing any single element from overpowering the others.
Solution Approach 2:
The system changes color parameters dynamically based on the display configuration. When a specific meter is displayed in scale-up mode or with eye-catching color, the system automatically adjusts other color parameters to compensate, thereby enhancing the specific meter's visibility while preserving the overall display balance.
3Quantity of substance
If navigation and meter data are displayed together to provide comprehensive information, then information completeness is improved, but color conflicts arise that reduce critical information recognition
Solution Approach 1:
The patent applies local quality by assigning different color characteristics to different display regions. The navigation display area uses one set of color properties while the meter and warning indicator areas use another set, allowing each region to optimize its visibility without interfering with others. This is achieved through separate color setting mechanisms for different display zones.
4Adaptability or versatility
If user can change navigation display design to conform with meter design, then customization flexibility is improved, but operation becomes cumbersome
Solution Approach 1:
The patent implements self-service by enabling the navigation display to automatically adapt its color scheme to match the meter display style. Instead of requiring users to manually configure both displays to be compatible, the system automatically performs the coordination, thereby maintaining design flexibility while eliminating the need for complex user operations.

AI summary
A display device for a vehicle has a display unit that has a meter display area and a navigation display area. The meter display area displays vehicle operation condition, and the navigation display area displays travel route guidance. When a display color changes in the travel route guidance in the navigation display area, color of the vehicle operation condition in the meter display area is also changed so that the color of the travel route guidance becomes more eye-catching than the vehicle operation condition.
