Dual-View Display With Micro-Lens Steering for Multi-Occupant Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems struggle to efficiently provide different types of data to multiple occupants without interference, occupying a single display size and location, especially when one occupant requires dynamic data and another static data.
Innovation Solution
A dual view display system using a micro-lens array and parallax barrier with addressable LED zones, allowing simultaneous projection of two different images at varying viewing angles, one as a heads-up display and the other as a direct display, by alternating LED zone luminance and micro-lens orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single display is used to provide data to multiple occupants, then device complexity is reduced, but it becomes difficult to provide different types of data (dynamic and static) to different occupants without interference
Solution Approach 1:
The display is segmented into multiple independently controllable LED zones, where each zone can display different data types (dynamic or static) simultaneously. This segmentation allows the display to serve multiple occupants with different data needs without requiring separate display devices, thus reducing overall system complexity while maintaining high adaptability.
2Adaptability or versatility
If different LED zones are energized at different luminances to create dual view display, then adaptability is improved, but energy consumption increases
Solution Approach 1:
The display employs time-division multiplexing where different LED zones are energized alternately at different luminances to create the dual view effect. By switching between displaying dynamic data at high luminance and static data at low luminance in periodic cycles, the system achieves adaptability while managing energy consumption more efficiently than continuous high-luminance operation would require.

Data Source
AI summary
A first image is generated at a first viewing angle during a first time by energizing a first LED zone to a first luminance. A second image is generated at a second viewing angle during a second time by energizing a second LED zone to a second luminance. The first luminance is directed at the first viewing angle by a first micro-lens disposed over the first LED zone and a parallax barrier. The second luminance is directed at a second viewing angle by a second micro-lens disposed over the second LED zone and the parallax barrier.
