Vehicle Display Layout With Offset Control Board for Thin Dash Integration
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 is mounted on the back face side of the display panel, facing 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
1Volume of moving object
If various components are disposed on the back side of the display screen, then the display device can be made more compact, but the thickness increases causing protrusion from the instrument panel
Solution Approach 1:
The patent divides the control circuit into two separate substrates: a control substrate containing the control circuit and an indicator substrate containing the light source component. This segmentation allows the control substrate to be positioned away from the display screen area, reducing the thickness at the protruding portion while maintaining all necessary functional components within the display device structure.
2Device complexity
If the control circuit is integrated on the back side of the display screen, then the device structure is simplified, but the thickness increases
Solution Approach 1:
The control substrate is positioned in a different spatial dimension relative to the display screen, specifically arranged to not face the display screen. This dimensional repositioning allows the control circuit to be separated from the thick back-side integration while maintaining functional connectivity, thus reducing the thickness at the front protruding portion.

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.
