Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereo image display apparatuses are unable to provide a natural viewing angle, especially at oblique angles, and suffer from poor image display quality, limiting their ability to create a vivid, three-dimensional effect.
Innovation Solution
A stereo image display apparatus incorporating a display device, a lens array layer with multiple lenses, and a directional structure that collimates light to reconstruct images for directional emission, allowing for improved viewing angles and enhanced image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stereo image display apparatuses use binocular vision fusion imaging technology, then they can display stereo images, but they cannot provide natural viewing angles at oblique positions and the image depth is limited
Solution Approach 1:
The display apparatus divides the display surface into multiple sub-pixels arranged in specific patterns, with each sub-pixel emitting light that is directed to different viewing angles through corresponding lens elements in the lens array, enabling simultaneous multi-angle viewing
Solution Approach 2:
The patent transitions from conventional planar 2D display to 3D立体 display by adding the lens array layer that redirects light in multiple directions, creating depth perception and allowing viewers at oblique angles to see the stereo image naturally
2Illumination intensity
If conventional display apparatuses emit light uniformly in all directions, then they can illuminate the display surface, but they cannot eliminate unwanted light orders and reduce image quality
Solution Approach 1:
The lens array is configured with lens elements that have specific focal lengths and positions corresponding to different sub-pixels, creating localized light redirection paths that direct light to specific viewing angles while blocking unwanted light orders
Solution Approach 2:
The lens array acts as an intermediary optical element between the display surface and the viewer, filtering and redirecting light to achieve directional emission and eliminate parasitic light orders that degrade image quality
