Multi-Layered Display Device for Vehicles with Expanded Visual Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices have limited ability to make the display area appear larger due to restricted movement of ring-shaped display partition members, which hides part of the display area when moved.
Innovation Solution
A display device with a first display surface showing vehicle information and a second display surface that can switch between displayed and hidden states, featuring a drawing pattern that spans across and outside the first display surface, enhancing the visual effect of a larger display area by coordinating vehicle information and drawing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a ring-shaped display partition member is moved over the display area, then well-defined display with increased stereoscopic effect is realized, but part of the display area is hidden by the ring-shaped display partition member
Solution Approach 1:
The patent introduces a second display surface positioned in front of the first display surface, creating a multi-layered display structure. The drawing pattern on the second display surface extends beyond the boundaries of the first display area, utilizing the depth dimension to expand the visual display area without occupying additional lateral space that would block the first display surface.
Solution Approach 2:
The second display surface with the drawing pattern is positioned in front of the first display surface, creating a nested arrangement where the drawing pattern visually encompasses the first display area. This nested structure allows the display partition member to move within the first display area while the drawing pattern on the second surface extends beyond its boundaries, making the overall display area appear larger.
2Area of stationary object
If the display area is expanded, then more information can be displayed, but the device complexity increases
Solution Approach 1:
The second display surface serves multiple functions: it displays the drawing pattern that extends beyond the first display area, and it also allows light to pass through to the first display surface when the drawing pattern is not needed. This multi-functionality enables the expansion of display area without proportionally increasing device complexity, as the same structural element (second display surface) performs both functions.
Solution Approach 2:
The second display surface is implemented as a thin, transparent structure that can be positioned in front of the first display surface. This thin-film approach allows the drawing pattern to extend beyond the first display area while maintaining a compact overall device structure, avoiding the need for bulky additional components that would increase device complexity.
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 creates a visual effect that makes the display area appear larger by using a second display surface with a drawing pattern that can be displayed or hidden, allowing for a more expansive and unified display of vehicle information, improving visibility and design flexibility.
Implementation Method 1
a second display surface configured to be disposed facing the first display surface and to transmit light
Implementation Method 2
the second display surface includes an indentation part forming the drawing pattern and can switch to the displayed state in which the drawing pattern is displayed by light radiated from a light source

AI summary
A display device includes a first display surface displaying vehicle information; and a second display surface which is disposed facing the first display surface and transmits light, has a drawing pattern drawn across a display area and outside the display area of the first display surface when seen from a direction in which the second display surface is stacked on the first display surface, and can switch to a displayed state in which the drawing pattern is displayed and a hidden state in which the drawing pattern is hidden. The display device displays information by the first display surface and the second display surface. The display device can therefore realize a visual effect that makes the display area look relatively large.
