Flexible Display Panel with Dual-Mode Pixels for Vehicle Pillar Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in simultaneously reducing blind spots created by vehicle pillars and providing adequate lighting for vehicle occupants when entering or exiting the vehicle, as these systems are typically independent and difficult to install together.
Innovation Solution
A flexible display apparatus with organic electroluminescent elements, including picture elements for image display and lighting, is attached to the vehicle pillar, utilizing active and passive matrix methods to emit red, green, and blue lights, and a separate element for enhanced lighting intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate display and lighting systems are installed on vehicle pillars, then both blind spot reduction and lighting functions can be achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent combines display and lighting functions into a single integrated system using a flexible display panel with dual-mode picture elements. Each picture element can operate in display mode (showing images) or lighting mode (providing illumination), eliminating the need for separate systems and reducing overall device complexity.
Solution Approach 2:
The flexible display panel is designed with multi-functional picture elements that can perform both display and lighting functions. This universal design allows the same component to serve multiple purposes: reducing blind spots through image display and providing illumination when needed, thereby increasing adaptability while maintaining simplicity.
2Adaptability or versatility
If multiple independent systems are installed on the pillar, then both image display and lighting functions are provided, but ease of installation deteriorates
Solution Approach 1:
By merging display and lighting functions into a single flexible panel, the patent reduces the number of installation steps and components. The integrated design allows for easier mounting on vehicle pillars compared to installing and aligning multiple independent systems.
Solution Approach 2:
The use of a flexible display panel enables the system to conform to the curved surface of vehicle pillars. This flexibility simplifies installation by eliminating the need for complex mounting structures and allows the panel to be easily attached to various pillar shapes and sizes.
3Stability of the object's composition
If a rigid display system is used on the pillar, then structural stability is maintained, but adaptability to different pillar shapes and ease of attachment deteriorate
Solution Approach 1:
The patent employs a flexible display panel that can be bent and shaped to match the contours of vehicle pillars. This flexibility allows the system to adapt to different pillar geometries while maintaining stable attachment through conformal contact, overcoming the limitations of rigid display systems.
