Solution Overview

Problem

Current display apparatuses in motor vehicles obstruct the driver's view and create a perceived loss of space due to their size, distracting the driver and reducing the feeling of personal space, especially with increasing autonomous driving features that require more display area.

Innovation Solution

A display panel with adjustable sections of light transmittance, allowing parts to be transparent or opaque based on user needs, integrated with a control device that sets light transmittance levels to minimize obstruction and enhance visibility of the environment, while prioritizing important information and reducing distraction during different driving modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display apparatus is made larger to provide more display area for autonomous driving functions, then the display capability is improved, but the visual obstruction to the driver and perceived loss of space increases

Engineering Contradiction:
Improvedisplay areaVSAvoidvisual obstruction
Core Design Contradiction:
Area of moving objectVSObject-affected harmful factors

Solution Approach 1:

The display panel dynamically changes its light transmittance properties based on driving modes and environmental conditions. During autonomous driving mode, the panel can become more transparent to reduce visual obstruction, while during manual mode it can be more opaque to enhance display visibility. This dynamic adaptation resolves the contradiction between display area and visual obstruction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the optical parameters of the display panel by adjusting light transmittance levels. The control device modifies the transmittance parameter according to different operating conditions, allowing the same physical display area to provide different levels of visual obstruction, thus resolving the contradiction between needing large display area and minimizing visual obstruction.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If the display apparatus is made more opaque to improve display visibility, then the display clarity is improved, but the perceived space and environmental visibility deteriorates

Engineering Contradiction:
Improvedisplay visibilityVSAvoidperceived space
Core Design Contradiction:
Illumination intensityVSVolume of stationary object

Solution Approach 1:

The display panel dynamically adjusts its opacity level based on driving conditions. During autonomous driving, the panel becomes more transparent to maintain perceived space and environmental visibility. During manual driving or when display information is critical, it becomes more opaque to enhance display visibility. This dynamic behavior resolves the contradiction between display visibility and perceived space.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If the display apparatus obstructs the driver's view to present more information, then the information display capability is improved, but the driver distraction and safety risk increases

Engineering Contradiction:
Improveinformation display capabilityVSAvoiddriver distraction
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts light transmittance based on driving mode detection. When autonomous driving mode is detected, the display panel increases transparency to minimize driver distraction while still providing information. When manual mode is detected, it increases opacity to enhance display visibility. This resolves the contradiction between information display capability and driver distraction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control device receives feedback about the driving mode (manual or autonomous) and automatically adjusts the display panel's light transmittance accordingly. This feedback mechanism ensures that the display adapts to current operational conditions, minimizing distraction when autonomous driving is active while maintaining information display capability when manual driving is active.

Inventive Principle:
Principle #23Feedback

AI summary

A display panel for displaying at least one graphical display object and a control device are part of a display apparatus in a motor vehicle. The display panel is freestanding in a space and has a multiplicity of predetermined sections, each having a settable degree of light transmittance. As a result, an environment of the display panel may be visible in the display panel, depending on the degree of light transmittance. The control device is configured to individually set a respective light transmittance to a predetermined degree for each of the multiplicity of predetermined sections of the display panel.
