Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting and display systems in vehicles do not provide a backplane that is configured for both high efficiency lighting and displaying videos and/or photos effectively.
Innovation Solution
A lighting and display backplane is designed with a substrate that integrates a non-matrix driving circuit layer for high efficiency lighting and a matrix driving circuit layer for image generation, separated by an insulator layer to prevent electrical interference, and includes multi-purpose LEDs for both functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single backplane is used for both lighting and display functions, then device complexity is reduced, but electrical interference between circuit layers occurs
Solution Approach 1:
An insulator layer is introduced as an intermediary between the non-matrix driving circuit layer and the matrix driving circuit layer. This insulator layer acts as a mediator that prevents electrical interference between the two circuit layers while allowing both lighting and display functions to operate on the same backplane, thus resolving the contradiction between device complexity and electrical interference.
2Use of energy by moving object
If non-matrix driving circuit is used for lighting, then lighting efficiency is improved, but display functionality is compromised
Solution Approach 1:
The backplane is segmented into two distinct circuit layers: a non-matrix driving circuit layer for high-efficiency lighting control and a matrix driving circuit layer for image and video display. This segmentation allows each layer to be optimized for its specific function while coexisting on the same backplane, resolving the contradiction between lighting efficiency and display capability.
Solution Approach 2:
The backplane is designed with multi-functionality by integrating both non-matrix and matrix driving circuit layers, enabling it to perform both lighting and display functions simultaneously. This universal design allows the same backplane structure to support diverse functions without compromising either lighting efficiency or display capability.
3Manufacturing precision
If matrix driving circuit is used for display, then image quality is improved, but lighting efficiency is reduced
Solution Approach 1:
The driving circuits are segmented into two separate layers with distinct functions: the matrix driving circuit layer handles display functions with high image quality, while the non-matrix driving circuit layer handles lighting functions with high efficiency. This functional segmentation resolves the contradiction between image quality and lighting efficiency by assigning each function to the most suitable circuit type.
