Vehicle Display Layout With Separated Substrates for Thin Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices installed on vehicles tend to protrude from the instrument panel due to their thickness, particularly because the components on the back side of the display screen contribute to a bulky appearance.
Innovation Solution
A display device design where the indicator substrate with light sources is mounted on the back face side to face the indicator region but not the display screen, and a separate control substrate is positioned to not face any part of the display screen or indicator substrate, allowing for a thinner profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are disposed on the back side of the display screen, then functionality is improved, but thickness increases
Solution Approach 1:
The patent divides the back-side components into separate functional substrates: an indicator substrate for light sources and a control substrate for control circuits. This segmentation allows each substrate to be independently positioned and optimized, reducing the overall thickness while maintaining all necessary functions.
Solution Approach 2:
The patent arranges components in different spatial dimensions rather than stacking them all in one location. The indicator substrate faces the indicator region while the control substrate is positioned to face neither the display screen nor the indicator substrate, creating a multi-dimensional layout that reduces thickness.
2Adaptability or versatility
If the display device protrudes from the instrument panel, then installation flexibility is improved, but appearance is worsened
Solution Approach 1:
The patent applies different spatial arrangements to different regions of the device. The indicator substrate is positioned to face the indicator region for local functionality, while the control substrate is positioned in a region that does not face either the display screen or indicator substrate, creating localized optimizations that collectively improve appearance.
Solution Approach 2:
By arranging substrates in different spatial dimensions and orientations, the patent reduces the overall protrusion of the display device from the instrument panel while maintaining installation flexibility.

AI summary
A display device includes a display panel in which a display screen and an indicator region are two-dimensionally arranged, an indicator substrate which is mounted with a light source component and which is arranged on a back face side of the display panel so as to face the indicator region but not to face the display screen, and a control substrate which is a separate part from the indicator substrate and on which a control circuit for the display screen is formed. The control substrate is arranged on the back face side of the display panel and arranged distant from the display panel than the indicator substrate, and the control substrate is arranged so as not to face at least a portion of each of the display screen and the indicator substrate.
