Vehicle Window Module With Non-Emissive Display Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window modules for vehicles that integrate information display screens often compromise aesthetics and violate light pollution regulations due to the presence of emissive screens that emit light, obstructing visibility and altering the module's appearance.
Innovation Solution
A non-emissive, backlight-free information display screen is integrated into the window module, fixed to the glass wall with a screen printing that opacifies part of the glass, allowing information to be viewed through designated windows while maintaining transparency or translucency, and the screen's perimeter is covered by screen printing or overmolding to enhance aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an emissive display screen with backlighting is used, then information visibility is improved, but light pollution increases and aesthetics deteriorate
Solution Approach 1:
The patent changes the fundamental parameter of the display screen from emissive to non-emissive, eliminating light emission while maintaining information visibility through reflective technology that uses ambient light instead of generating light
Solution Approach 2:
The patent converts the limitation of non-emissive screens (requiring ambient light) into a benefit by using the vehicle's existing lighting environments to illuminate the display, thereby eliminating light pollution while maintaining visibility
2Loss of information
If an emissive display screen is used, then information visibility is improved, but the module aesthetics are altered
Solution Approach 1:
The patent changes the display technology parameter from emissive to non-emissive, which fundamentally alters how the screen interacts with light and allows it to blend with the surrounding glass wall appearance when not in use
Solution Approach 2:
The patent applies different optical properties to different areas: the display screen area remains visually integrated with the glass wall through matching refractive indices and non-emissive properties, while the screen printing areas provide contrast and definition, creating local visual quality variations that enhance overall aesthetics
3Loss of information
If the screen size is increased for better readability, then information visibility is improved, but the window module aesthetics are compromised
Solution Approach 1:
The patent changes the optical parameter of the display screen to be non-emissive and match the refractive index of the glass wall, allowing the screen to become visually imperceptible when not displaying information, thereby eliminating the need for large screen areas to maintain aesthetics
4Shape
If screen printing covers the entire glass wall for aesthetics, then module appearance is improved, but display area visibility is blocked
Solution Approach 1:
The patent segments the glass wall into distinct functional zones: areas with screen printing for aesthetic definition and structural identification, and clear areas without screen printing that serve as the display region, allowing both aesthetics and visibility to coexist
Solution Approach 2:
The patent applies screen printing selectively to specific areas of the glass wall while leaving the display area clear, creating local quality differences that serve different functions: aesthetic definition in printed areas and optical clarity in the display area
5Object-generated harmful factors
If a non-emissive screen without backlighting is used, then light pollution is reduced and aesthetics are improved, but information visibility requires careful design
Solution Approach 1:
The patent changes the display screen parameter from emissive to non-emissive and eliminates backlighting, fundamentally altering the visibility mechanism to rely on ambient light reflection while maintaining readability through optimized optical properties
Solution Approach 2:
The patent introduces ambient light as an intermediary that enables display visibility without requiring active light emission from the screen itself, using environmental light sources to illuminate the reflective display surface
