Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices require a large number of light sources and optical elements to display multiple viewpoint images, leading to increased device size and cost due to the need for high position accuracy of lenses and lasers across a wide range.
Innovation Solution
An image display device that uses a single image source to generate a two-dimensional projection image, which is divided into multiple area images and deflected at different angles onto a screen with anisotropic diffusion properties, allowing partial overlap to create multiple viewpoint images without the need for multiple light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple light sources and optical elements are used to display multiple viewpoint images, then the quality of multi-view display is improved, but the device size and cost increase
Solution Approach 1:
The patent merges multiple viewpoint images into a single projection image that is then divided into multiple areas. Instead of using separate light sources for each viewpoint, one light source projects an image that is spatially divided and deflected to create multiple viewpoint images on the screen, reducing device complexity while maintaining multi-view functionality
Solution Approach 2:
The projection image is divided into multiple area images corresponding to different viewpoints. The image deflection section divides the single projection image into multiple areas in the horizontal direction, with each area being deflected at different angles to form distinct viewpoint images on the screen
2Reliability
If multiple light sources and optical elements are used to display multiple viewpoint images, then the quality of multi-view display is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the functions of multiple light sources and optical elements into a single light source with an image deflection section. This consolidation reduces the number of components that need to be manufactured and assembled, thereby reducing manufacturing cost while achieving the same multi-view display effect
Solution Approach 2:
The image deflection section serves multiple functions: it divides the projection image into multiple areas, deflects each area at different angles, and creates multiple viewpoint images simultaneously. This multi-functional component replaces what would traditionally require multiple specialized optical elements, reducing overall system cost
3Manufacturing precision
If high position accuracy of lenses and lasers is maintained across a wide range, then the image display precision is improved, but the device size and cost increase
Solution Approach 1:
The image deflection section acts as an intermediary that handles the complex task of spatial division and angular deflection. This allows the light source to operate at a fixed position with standard accuracy, while the image deflection section performs the precise spatial manipulation needed to create multiple viewpoints, reducing the overall system's position accuracy requirements
