Vehicle Display Apparatus with Segmented Numerical and Drawing Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face challenges in maintaining visibility of non-enlarged information when an image representing specific information, such as vehicle speed, is enlarged on the display panel, leading to decreased recognition of other essential information like vehicle speed due to reduced display area and difficulty in distinguishing multiple information items displayed side by side.
Innovation Solution
The vehicle display apparatus employs a dual-display area system where a first area constantly displays numerical information like vehicle speed, and a second area displays changing information, with the second area's content overlapping partially with the first. A control unit adjusts the display to ensure the numerical information remains visible and recognizable by shrinking the drawing image when the second information is enlarged, maintaining priority on the first information's visibility.

1Illumination intensity
If the second display area is enlarged to display specific information (e.g., obstacle image), then the visibility of the second information is improved, but the display area for the first information is reduced, causing the first information to be obscured or hard to recognize
Solution Approach 1:
The display panel is segmented into a first display area for constantly displaying numerical information (e.g., vehicle speed) and a second display area for displaying changing information (e.g., obstacle images). The first display area is further divided into a numerical value display region and a drawing image display region. This segmentation allows the second display area to be enlarged for improved visibility of specific information while the first display area maintains its functionality for essential numerical information, resolving the contradiction between visibility improvement and display area reduction.
2Measurement precision
If the second display area is enlarged to improve visibility of specific information, then recognition of the second information is improved, but the drawing image in the first display area overlaps with the enlarged second information, causing difficulty in distinguishing multiple information items
Solution Approach 1:
The first display area is segmented into distinct functional regions: a numerical value display region that constantly displays numerical information and a drawing image display region that displays graphical representations. When the second display area is enlarged, the drawing image in the first display area is positioned in an outer peripheral portion adjacent to the numerical display image, ensuring that the numerical information remains clearly visible and distinguishable from the enlarged second information, thus resolving the information distinction complexity.
Solution Approach 2:
Different regions of the first display area are assigned different display qualities and functions. The numerical value display region maintains constant visibility with high contrast and clear positioning, while the drawing image display region is positioned in the outer peripheral portion and can be adjusted or shrunk when the second display area is enlarged. This local quality differentiation ensures that essential numerical information remains easily distinguishable even when the second information is enlarged.
