Light Beam Deflection for Wider Multi-Viewer Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses face a challenge in increasing the viewing area without enlarging their volume, as larger apertures lead to increased space occupation, limiting the size of the viewing area.
Innovation Solution
A display apparatus utilizing an image source module and a light beam deflection module to transmit and deflect image source light beams to multiple viewing areas in periodicities, effectively expanding the viewing area without increasing the apparatus' volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the aperture of the lens is increased to increase the viewing area, then the viewing area size is improved, but the volume of the display apparatus increases
Solution Approach 1:
The patent divides a single large viewing area into multiple smaller viewing areas (first viewing area, second viewing area, etc.) that can be selectively activated. This segmentation allows the system to provide multiple viewing positions without requiring a single large aperture lens, thus resolving the contradiction between viewing area size and apparatus volume.
Solution Approach 2:
The patent employs periodic switching between different light beam deflection states to direct light to different viewing areas. By alternating between deflection states in different periodicities, the system creates multiple effective viewing areas over time without requiring all areas to be simultaneously accessible through a large aperture, thereby maintaining compact volume while expanding total viewing capacity.
2Adaptability or versatility
If multiple viewing areas are provided to support simultaneous viewing by multiple viewers, then the viewing capability is improved, but the device complexity increases
Solution Approach 1:
The patent uses a dynamically controllable light beam deflection module that can switch between different deflection states. This dynamic control allows a single optical path to serve multiple viewing areas sequentially, avoiding the need for multiple static optical paths and reducing overall system complexity while maintaining multi-viewer capability.
Solution Approach 2:
The light beam deflection module is designed to perform multiple functions by switching between different deflection states. The same module serves all viewing areas at different times, making it a universal component that replaces what would otherwise require multiple separate optical systems, thereby reducing device complexity.

AI summary
In an imaging method, an image source transmits N image source light beams to a light beam deflector in K periodicities, where N is a positive integer greater than or equal to 2, and K is a positive integer greater than or equal to 1. The light beam deflector deflects transmission directions of the N image source light beams to a plurality of viewing areas, where the N image source light beams transmitted to the plurality of viewing areas are respectively imaged in a plurality of display areas.
