Flexible OLED Cabin Displays for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-distance flights can be monotonous due to limited and heavy entertainment systems in aircraft, with conventional monitors being small and not providing an optimal viewing experience for all passengers, and they contribute to weight and space issues in aircraft design.
Innovation Solution
A visualisation system using translucent flexible displays made of organic light emitting diodes (OLEDs) integrated into the cabin lining panels, which can be applied directly or on a flexible substrate, offering a wide angle of view and eliminating the need for background illumination, allowing for immersive graphic presentations and illumination scenarios without compromising the aesthetic surface quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional flat-panel monitors are arranged in the cabin, then passengers can access entertainment and information, but the monitors are heavy and occupy significant space
Solution Approach 1:
The patent applies flexible display technology that can be conformally mounted on cabin surfaces, replacing heavy rigid monitors with lightweight flexible OLED panels that maintain functionality while significantly reducing weight and space occupation
Solution Approach 2:
The patent replaces traditional mechanical monitor structures with a flexible display system that uses organic light-emitting diodes, eliminating the need for heavy housing and mounting mechanisms while maintaining display functionality
2Ease of operation
If small flat-panel monitors are installed in backrests, then individual passengers can view content, but the viewing experience is limited due to small size
Solution Approach 1:
The patent transitions from small individual displays to large-scale immersive displays by utilizing the three-dimensional cabin space, creating wraparound or ceiling-mounted displays that provide expansive viewing areas while maintaining accessibility for passengers
3Adaptability or versatility
If distributed monitors are arranged in the cabin, then entertainment can be provided, but only a few passengers have unrestricted view of the monitors
Solution Approach 1:
The patent creates a universal display system where flexible displays are strategically positioned throughout the cabin (on ceilings, walls, and curved surfaces) to serve all passengers regardless of seat location, ensuring that every passenger has access to the entertainment and information content
4Adaptability or versatility
If lining panels are coated with displays, then aesthetic surface quality may be compromised, but the display functionality is enhanced
Solution Approach 1:
The patent uses flexible OLED display films that can be conformally mounted on curved or flat lining panels, allowing the display to integrate with the existing aesthetic design of the cabin interior while maintaining full display functionality, as the flexible nature of the OLED allows it to follow the contour of the surface without creating visible disruptions
Solution Approach 2:
The patent utilizes the ability of OLED displays to control light emission and transparency, allowing the display to blend with or enhance the aesthetic qualities of the lining panel surface while providing full display functionality when activated
