Transparent Dashboard Display Control for Visibility and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up displays in vehicles face issues with visibility in bright environments and comfort due to light projection, while digital side mirrors consume excessive power, leading to rapid battery depletion.
Innovation Solution
A vehicle equipped with a transparent LCD or OLED display on the dashboard that adjusts height and transparency based on driving mode, along with a control method that optimizes the display and side mirror operation to reduce power consumption and enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional head-up display projects light on a transparent screen, then an image can be formed on the screen, but the image may not be visible well when the external environment is bright
Solution Approach 1:
The patent employs a transparent display device with adjustable transparency parameters. The controller dynamically changes the transparency parameter of the display panel based on ambient light conditions, allowing the display to maintain visibility across varying brightness environments. This resolves the contradiction by making the transparency a variable parameter rather than a fixed property.
Solution Approach 2:
The display device transitions from a static transparency state to a dynamic one, where the transparency level can be adjusted in real-time. The controller receives ambient light information and automatically adjusts the display's transparency parameter accordingly, enabling the system to adapt to changing external conditions and maintain optimal image visibility.
2Reliability
If a digital side mirror always operates at the highest performance, then the rear lateral image can be clearly output, but power consumption increases and battery charge amount decreases rapidly
Solution Approach 1:
The patent implements a strategy where the digital side mirror operates at full performance only when necessary. The controller monitors driver behavior and ambient conditions, activating the high-performance mode selectively rather than continuously. This partial action approach maintains image quality when needed while significantly reducing overall power consumption during normal operation.
Solution Approach 2:
The system dynamically adjusts the operational parameters of the digital side mirror based on real-time conditions. When the driver is not observing the side mirror or when conditions permit, the system reduces its operational intensity, changing parameters such as camera activation state and display brightness to minimize power consumption while maintaining acceptable image quality when required.
3Ease of operation
If a transparent display is provided on the dashboard, then driver comfort and visibility can be improved, but the display height must be adjusted for different driving modes
Solution Approach 1:
The patent implements a movable display structure that can adjust its vertical position dynamically. The display mounting structure includes actuation mechanisms that allow the display panel to move between different height positions, enabling adaptation to various driving modes and driver preferences while maintaining optimal viewing comfort.
Solution Approach 2:
The display system is designed to serve multiple functions across different driving scenarios. By incorporating height adjustment capability, the single display unit can accommodate both manual and autonomous driving modes, as well as different driver seating positions, making it a universal solution that enhances comfort across diverse operational contexts.
