Single Projector Multiple View Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems require multiple projectors to display different images at various locations, which increases costs and complexity, while also limiting the ability to achieve high width-to-height aspect ratios.
Innovation Solution
A multiple view display system that uses a single projector to time-multiplex and control the projection of different images to multiple locations through an image propagation control means, allowing each image to be projected during a distinct time period and directed along specific pathways using mirrors and shutters.

Engineering Contradiction Analysis
1Area of stationary object
If multiple projectors are used to display different images at various locations, then the display coverage and image quality are improved, but the cost and system complexity increase
Solution Approach 1:
The patent employs time-multiplexing where a single projector alternates between projecting different images to different locations in periodic time slots. The display controller switches the projector's output between multiple destinations sequentially, creating the effect of multiple simultaneous displays using one projector. This periodic switching resolves the contradiction by achieving multi-location coverage without requiring multiple projectors, thus reducing system complexity and cost.
Solution Approach 2:
The single projector is designed to perform multiple functions by projecting different images to different locations at different times. The display controller enables the projector to serve multiple display purposes sequentially, making one device fulfill the role of multiple projectors. This multi-functionality approach reduces the number of components needed while maintaining comprehensive display coverage.

If multiple projectors are used to achieve high width over height aspect ratios, then the display aspect ratio is improved, but the cost increases
Solution Approach 1:
The patent extends the display in the temporal dimension by using time-multiplexing to project different portions of a wide-aspect-ratio image to different locations sequentially. Instead of requiring multiple projectors arranged spatially to achieve a wide aspect ratio, the system uses a single projector that switches between different projection targets over time, effectively creating a wide display area through temporal rather than spatial arrangement.
3Device complexity
If a single projector is used to project images to multiple locations, then the cost is reduced, but the ability to display different images simultaneously at multiple locations is limited
Solution Approach 1:
The display controller implements periodic switching that allocates different time slots to different projection destinations. During each time slot, the projector displays a specific image to a specific location. This periodic action creates the functional equivalent of simultaneous multi-location displays using a single projector, maintaining high productivity despite the lower hardware cost.
