Vehicular Display Panel Switching for Door-Obscured Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving vehicles, display panels on vehicle bodies can be obscured by movable parts like doors or windows, reducing visibility and display effectiveness, and high-resolution panels increase costs.
Innovation Solution
The vehicular display device includes multiple panels with varying resolutions, and an image control unit adjusts display forms based on the operation of doors or windows, ensuring images are displayed on visible panels, and images are transferred or resized as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel is provided on the vehicle body, then the display effect is enhanced, but the image cannot be visually recognized due to opening and closing of the door
Solution Approach 1:
The patent applies dynamics by making the display system adaptive to door movement states. The control unit detects door opening/closing operations and dynamically switches between the first display panel (on vehicle body) and the second display panel (on door) to ensure continuous image visibility. This resolves the contradiction by making the display system flexible rather than static, allowing it to adapt its configuration based on real-time door position.
Solution Approach 2:
The control unit acts as an intermediary that manages the transition of image display between the first display panel and the second display panel. When the door opens, the control unit transfers the image from the vehicle body panel to the door panel, ensuring seamless continuity. This intermediary mechanism resolves the visibility issue by coordinating between multiple display components.
2Manufacturing precision
If a high-resolution display panel is used, then the image quality is improved, but the cost increases
Solution Approach 1:
The patent applies local quality by assigning different resolution requirements to different display panels based on their specific functions and viewing conditions. The first display panel (on vehicle body) and the second display panel (on door) can have different resolutions, with each optimized for its particular use case. This allows the system to achieve overall high image quality without requiring all panels to be high-resolution, thereby reducing costs.
3Area of stationary object
If the display panel is arranged on the vehicle body including window, then the display surface area is increased, but the image is obscured by the window
Solution Approach 1:
The patent segments the display system into multiple independent display panels: a first display panel arranged on the vehicle body (including window areas) and a second display panel arranged on the door. This segmentation allows the system to maintain large total display area while ensuring that images can be displayed on visible portions. When the window obscures part of the display, the system can switch to or supplement with the door-mounted panel.

AI summary
A vehicular display device includes at least one display panel arranged on a vehicle body of a vehicle and configured to display an image, and a display control unit configured to control display of the image. The display panel includes a movable portion provided on the vehicle body, and the display control unit includes an image control unit configured to control a display form of an image when the movable portion is operated. An image displayed on a display panel in a state where the display is hidden due to the operation of the movable portion is displayed on the display panel of the movable portion.
