Multi-View Display with Blocking Layer for Independent Interior Exterior Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems in vehicles face challenges in providing distinct visual experiences for occupants inside and outside the vehicle, as existing display technologies do not efficiently allow for simultaneous and independent pattern generation on interior and exterior surfaces.
Innovation Solution
A multi-view display system with laminated layers, including polymer films with fluorescent materials and ultraviolet-blocking layers, is integrated into vehicles, allowing for the simultaneous display of different patterns on interior and exterior surfaces using separate energy sources, with rigid layers ensuring transparency and energy control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display screen is used for both interior and exterior views, then device complexity is reduced, but the ability to display distinct patterns independently on each side is lost
Solution Approach 1:
The display system is segmented into two independent display screens (first display screen for interior, second display screen for exterior) separated by a blocking layer. Each screen can display distinct patterns independently while sharing a common structural framework, resolving the contradiction between independent display capability and system complexity.
Solution Approach 2:
The first and second display screens are nested within a shared laminated structure containing rigid layers, polymer films, and blocking layers. This nested arrangement allows two independent display functions to coexist within a single integrated assembly, achieving independent pattern display without proportionally increasing overall system complexity.
2Illumination intensity
If transparent rigid layers are used to maintain visibility, then exterior view transparency is improved, but energy control and pattern visibility are compromised
Solution Approach 1:
A blocking layer is introduced as an intermediary element between the first and second display screens. This blocking layer selectively prevents energy (light) from passing through from one side to the other, eliminating harmful energy interference while allowing each display to maintain its required transparency and illumination characteristics independently.
Solution Approach 2:
The system uses composite laminated structures combining transparent rigid layers with blocking layers and fluorescent polymer films. These composite materials enable simultaneous achievement of transparency for exterior views and selective energy blocking for independent pattern display, resolving the contradiction between transparency and energy control.
3Illumination intensity
If fluorescent polymer films are used for display, then color emission capability is improved, but energy consumption increases
Solution Approach 1:
The system replaces traditional high-energy display mechanisms with fluorescent polymer films that convert ultraviolet energy to visible light through photoluminescence. This substitution provides superior color emission capability while reducing overall energy consumption, as the fluorescent materials efficiently convert energy across the visible spectrum.
Solution Approach 2:
The display system utilizes fluorescent polymer films with adjustable fluorescent materials that can be tuned to emit specific colors and wavelengths. By changing the parameters of the fluorescent materials, the system achieves optimal color emission capability while minimizing energy consumption for each display requirement.

Function Achieved in This Case
Enables the simultaneous display of distinct images or patterns inside and outside the vehicle, enhancing occupant experience while providing a visible exterior display, optimizing viewing experiences for both interior and exterior viewers.
Implementation Method 1
The first display screen includes a first polymer film provided with fluorescent material... generating a first pattern by emission of energy from the first source to a portion of the first polymer film
Implementation Method 2
The second display screen includes a second polymer film provided with fluorescent material... generating a second pattern by emission of energy from the second source to a portion of the second polymer film
Implementation Method 3
The blocking layer is configured to selectively inhibit energy transmission from the first side to the second side... an ultraviolet-blocking layer disposed between the first polymer film and the second polymer film

AI summary
An automotive vehicle includes a cabin, a controller, and a multi-view display. The multi-view display has a first side facing the cabin and a second side facing the exterior of the vehicle. The multi-view display has a first-side display screen, a second-side display screen, and a blocking layer disposed between the first-side display screen and the second-side display screen. The first-side display screen and the second-side display screen are in communication with the controller and operable to display a first pattern on the first-side display screen and a second pattern, distinct from the first pattern, on the second-side display screen.
