Vehicular Display Half Mirror Decorative Member Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular display apparatuses face issues where decorative members obstruct the screen during image display, and attempting to display these members using liquid crystal displays results in insufficient three-dimensional representation and a decreased appearance.
Innovation Solution
A vehicular display apparatus incorporating a liquid crystal display, a half mirror, a first decorative member, and a light emitting member that projects light onto the decorative member, allowing it to appear as a virtual three-dimensional element when illuminated and preventing obstruction by making it invisible when not lit, while maintaining a good appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decorative member is provided on the front of the liquid crystal display, then a three-dimensional appearance can be achieved, but the decorative member becomes an obstacle and obstructs the display
Solution Approach 1:
The decorative member's visibility is made dynamic through lighting control. When the light emitting member illuminates the decorative member, it becomes visible and provides three-dimensional appearance. When not illuminated, it becomes invisible and does not obstruct the display. This dynamic visibility resolution allows the system to switch between the two conflicting states.
Solution Approach 2:
The decorative member's visual presence is controlled through lighting effects. The light emitting member changes the visual state of the decorative member from invisible to visible by projecting light onto it, thereby controlling its appearance without physical movement or structural change.
2Object-affected harmful factors
If the decorative member is displayed by the liquid crystal display, then display obstruction is prevented, but representation of the third dimension becomes insufficient and appearance decreases
Solution Approach 1:
The display system is segmented into two functional parts: the liquid crystal display handles two-dimensional image information, while the physical decorative member handled by the light emitting member provides three-dimensional appearance. This segmentation allows each component to excel at its specific function without compromising the other.
Solution Approach 2:
The light emitting member acts as an intermediary between the liquid crystal display and the decorative member. It projects light onto the decorative member to create a virtual three-dimensional image that complements the two-dimensional display, thereby enhancing the overall three-dimensional appearance without obstructing the display content.
3Object-affected harmful factors
If a light emitting member is added to control decorative member visibility, then display obstruction is prevented while maintaining appearance, but device complexity increases
Solution Approach 1:
The light emitting member serves multiple functions: it illuminates the decorative member to create three-dimensional appearance, controls the visibility of the decorative member to prevent display obstruction, and can potentially provide ambient lighting. This multi-functionality justifies the addition of the component by providing multiple benefits from a single element.
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 prevents decorative members from obstructing the screen while maintaining a three-dimensional appearance, enhancing the display's aesthetics and functionality by dynamically controlling the visibility of the decorative elements based on lighting conditions.
Implementation Method 1
a half mirror that is provided on a back side of the vehicle with respect to the liquid crystal display, transmits an image from the liquid crystal display to the back of the vehicle, and reflects light from a direction intersecting with a front-back direction of the vehicle to the back of the vehicle

AI summary
A vehicular display apparatus can be provided on a vehicular instrument panel and the apparatus provides a display for a vehicular crew. The apparatus can include; a half mirror located at a back side of the vehicle with respect to the liquid crystal display, the half mirror configured to transmit an image from the liquid crystal display to the back of the vehicle, and to reflect light from a direction intersecting with a front-back direction of the vehicle to the back of the vehicle, a first decorative member located at a side of the intersecting direction, and a light emitting member configured to irradiate light at least one of from and towards the first decorative member.
