Vehicle Display Image Switching at Monocular-Binocular Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices experience reduced visibility and discomfort due to differences in image perception between the left and right eyes when images are displayed across the boundary of single-eye and both-eye recognition regions.
Innovation Solution
A vehicle display device with a control unit that switches between first and second images based on the display position, where the first image is displayed in a region visually recognized by both eyes and the second image, featuring a pattern different from the first, with combined low and high luminance portions, to minimize visibility issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an image is displayed at a boundary between a display region visually recognized with only one eye and a display region visually recognized with both eyes, then the entire display surface can be utilized, but the visibility of the image is reduced and the driver may feel uncomfortable
Solution Approach 1:
The patent applies local quality by displaying different image patterns in different regions of the display surface. Specifically, a first image pattern is displayed in the first region (visually recognized by both eyes) and a second image pattern is displayed in the second region (visually recognized by only one eye). This allows each region to be optimized for its specific visual characteristics, improving overall visibility while utilizing the entire display surface.
2Area of stationary object
If an image is displayed at a boundary between regions recognized by one eye and both eyes, then the display range is expanded, but the image shape differs between eyes causing driver discomfort
Solution Approach 1:
The patent implements local quality by using different image patterns in different display regions. The first image pattern is used in the binocular region while the second image pattern is used in the monocular region, creating a display strategy adapted to local visual characteristics and reducing driver discomfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces discomfort and enhances visibility by making boundary lines less noticeable through controlled luminance distribution and image pattern adjustments.
Implementation Method 1
an optical system that projects display light of the image toward a reflection surface in front of a driver

AI summary
A vehicle display device includes an image display device having a display surface that displays an image, an optical system that projects display light of the image toward a reflection surface in front of a driver, and a control unit, wherein the display surface includes a first region and a second region, wherein the control unit causes the image display device to display a first image when a display position of the image is in the first region, and causes the image display device to display a second image when a display position of the image is in a boundary between the first region and the second region, and wherein the second image is an image having a pattern different from a pattern of the first image, and has a configuration in which a low luminance portion and a high luminance portion are combined.
