Vehicular Display Panel Control Around Door Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving vehicles, the display effect of a vehicular display device is compromised due to movable parts like doors and windows, which obstruct the view of the displayed image, and the image may not be recognizable from varying distances or positions, especially for viewers with low luminance or contrast.
Innovation Solution
A vehicular display device with multiple display panels and a control unit that adjusts the image display based on the operation of movable parts and viewer position, using low and high-resolution panels to ensure image visibility and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
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 panel movable rather than fixed. The display panel is configured to move between a first position (when the door is closed) and a second position (when the door is open), allowing it to adapt its position based on the door state to maintain both display effect and visual recognition
Solution Approach 2:
The patent segments the display system into multiple positions for the display panel. By dividing the display panel's operational space into distinct positions (first position for closed door, second position for open door), the system can optimize display performance for each specific door state
2Measurement precision
If an image with large size is displayed, then distant viewers can visually recognize the image, but the resolution of the display panel is reduced
Solution Approach 1:
The patent applies dynamics by enabling the display panel to change its position dynamically. By moving the display panel to different positions based on door state and viewer distance, the system can optimize the balance between image size for distant visibility and resolution quality without requiring a permanently low-resolution panel
Solution Approach 2:
The patent solves the resolution vs. size contradiction by introducing a spatial dimension - moving the display panel to different positions in space. This allows the same high-resolution panel to effectively display large images for distant viewers by positioning it optimally, rather than sacrificing resolution

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.
