Motor Vehicle Display Transparency Control With Segmented Backlighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies for motor vehicles face limitations in achieving high transparency and contrast, with existing switchable foils and displays only offering partial transparency and resolution, which affects the visibility and spatial perception of graphical elements.
Innovation Solution
A display device with a sight protection element that adjusts transparency for subareas of a display screen unit, combined with a back lighting module that illuminates specific areas, allowing for enhanced perceived transparency and contrast by controlling the degree of opacity and illumination independently for each subarea.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If switchable foils or films are used to control transparency, then the degree of transparency can be adjusted, but the perceived transparency and contrast are reduced due to multiple layers and limited transparency percentages
Solution Approach 1:
The patent extracts the backlighting function from the display structure by placing illumination elements behind the display screen unit, separate from the sight protection element. This allows independent control of illumination and transparency, eliminating the need for complex multi-layer integrated structures while achieving high perceived transparency.
Solution Approach 2:
The display screen unit is divided into multiple subareas with independently controllable sight protection elements and illumination elements. This segmentation allows different transparency levels and illumination intensities for different regions, optimizing both perceived transparency and contrast without requiring a single complex uniform structure.
2Illumination intensity
If the display screen unit is made more transparent, then visibility of graphical elements is improved, but contrast is reduced making graphical elements harder to distinguish
Solution Approach 1:
The patent applies different transparency and illumination characteristics to different subareas of the display screen unit. Each subarea can be independently optimized with specific sight protection element transparency and illumination intensity, allowing high contrast in graphical element regions while maintaining high overall transparency where needed.
Solution Approach 2:
The sight protection elements and illumination elements are dynamically controllable, allowing real-time adjustment of transparency and illumination levels. This enables adaptive optimization of contrast and visibility based on display content and environmental conditions, maintaining high perceived transparency while preserving graphical element distinguishability.
3Illumination intensity
If uniform transparency is applied across the entire display screen unit, then manufacturing is simplified, but spatial perception and visibility are reduced due to inability to optimize specific areas
Solution Approach 1:
The display screen unit is divided into multiple subareas, each with independently controllable sight protection and illumination elements. This segmentation enables localized optimization of transparency and illumination for different functional regions, enhancing spatial perception and visibility without requiring entirely complex custom structures.
Solution Approach 2:
The modular subarea structure with independent sight protection and illumination control provides multi-functionality, allowing the same basic structure to serve different purposes in different regions (e.g., high transparency for viewing areas, high contrast for display areas). This universal modular approach balances complexity with performance.

AI summary
A display screen unit of a display device includes a display surface having a plurality of subareas, and a sight protection element configured to set a degree of transparency for each of the plurality of subareas. The display device further includes a back lighting module having at least one illumination element directed to the display screen unit, and a controller configured to set the display screen unit in a display mode, in which the sight protection element sets the degree of transparency for each of the plurality of subareas. The controller may be configured to provide a back light by controlling the back lighting module based on a movement of the display screen unit from a stowed position to a deployed position.
