Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro-LED transparent displays face challenges in blending physical and virtual images due to focus adjustments, causing blurring of physical images when viewed alongside virtual ones, leading to a poor user experience.
Innovation Solution
A three-dimensional display system with a parallax optical module, featuring staggered light-emitting elements arranged in a checkerboard format, uses optical correction layers and microstructure units to output stereoscopic images at different depth positions, allowing clear viewing of both physical and virtual images by adjusting the projection direction and depth perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent display is used to display virtual images, then the see-through characteristic allows users to see the physical scene behind the display, but the virtual image and physical image are at different distances causing the physical image to appear blurred when viewed simultaneously
Solution Approach 1:
The display screen is segmented into multiple depth layers (first depth display units and second depth display units) arranged in a checkerboard pattern. Each depth layer displays images at specific depth positions, allowing the system to provide clear visual information at multiple depths simultaneously, thereby resolving the blurring problem when viewing both virtual and physical images
Solution Approach 2:
The invention transitions from a traditional two-dimensional display to a three-dimensional depth-resolved display by adding the depth dimension. Light-emitting elements are arranged at different depth positions along the optical axis, enabling the display to output images at multiple depth layers, which allows users to clearly perceive both near and far images without mutual interference
2Manufacturing precision
If light-emitting elements are arranged at different depth positions to output stereoscopic images, then clear viewing at multiple depths is achieved, but the device structure becomes more complex
Solution Approach 1:
The invention merges the display function with the optical guiding function into a single integrated structure. The display screen itself serves as both the light emission source and the optical path guidance medium, eliminating the need for separate optical components. This integration reduces device complexity while maintaining the capability to display clear stereoscopic images at multiple depths
Solution Approach 2:
The display screen is designed to perform multiple functions simultaneously: it serves as the light emission source, the structural support, and the optical path guidance medium. This multi-functionality reduces the number of separate components needed, thereby simplifying the overall device structure while achieving complex stereoscopic display capabilities

AI summary
A stereoscopic three-dimensional display and manufacturing method thereof includes a three-dimensional display and a depth sensor. The three-dimensional display includes a three-dimensional display module and a parallax optical module that corresponds to a plurality of first depth display portions and a plurality of second depth display portions and a first parallax optical portion and a second parallax optical portion. The depth sensor is electrically connected to the stereoscopic display module, and detects the distance between the user and the stereoscopic display, and selects whether all of the first depth display parts jointly output the first parallax image, or all of the second depth display parts jointly output the second parallax image, so that the user can view the stereoscopic imaging through the first parallax optical unit or the second parallax optical unit at different positions.
