Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto-multiscopic 3D display systems with concave mirror arrays are limited in their ability to maintain efficient light focusing due to fixed structural configurations, which restricts their functionality when the arrangement of transparent spots or lines on the parallax barrier changes.
Innovation Solution
An auto-multiscopic 3D display system with adjustable light-focusing capability using an electromechanical system with pivotably mounted and controllable mirrors that reflect light towards clear spots or lines on an image source layer, allowing the system to maintain efficient light exit even when the arrangement of transparent spots or lines on the parallax barrier changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed concave mirror array is used in the display system, then the structural configuration is simple and stable, but the light focusing capability cannot be adjusted when the arrangement of transparent spots or lines on the parallax barrier changes
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed concave mirror array with an electromechanical system of pivotably mounted mirrors that can be dynamically controlled to change their orientation and position. This allows the mirror system to adapt to different arrangements of transparent spots or lines on the parallax barrier, providing adjustable light focusing capability while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the arrangement of transparent spots or lines on the parallax barrier is changed to improve display flexibility, then the adaptability of the display system is improved, but the fixed mirror array cannot maintain efficient light focusing
Solution Approach 1:
The patent implements feedback by controlling the electromechanical mirror system based on the arrangement of transparent spots or lines on the parallax barrier. The system can detect or receive information about the transparent spot/line configuration and adjust the mirror positions and orientations accordingly to maintain efficient light focusing, ensuring that light is correctly directed through the dynamically arranged transparent elements.
3Adaptability or versatility
If an electromechanical system with pivotable mirrors is used to provide adjustable light focusing, then the adaptability to changing parallax barrier configurations is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the mirror system into multiple individually controllable mirror elements within the electromechanical system. Each mirror can be independently positioned and oriented, allowing flexible light focusing for different transparent spot/line arrangements while keeping each individual mirror component relatively simple. This modular segmented approach reduces overall system complexity compared to a single complex adjustable mirror.

Function Achieved in This Case
Enables efficient focusing and emission of light, maintaining 3D image quality and allowing for dynamic adjustments in the display system's configuration, such as altering the size, shape, and location of transparent spots or lines, resulting in a thin form factor and enhanced display capabilities.
Implementation Method 1
The electromechanical system includes a mirror that is pivotably mounted and controllable to reflect light sent to the mirror from the image source layer towards the clear spot
Data Source
AI summary
An apparatus for displaying auto-multiscopic 3D images includes a parallax barrier; an image source layer with a first side facing the rear surface of the parallax barrier; and an electromechanical system facing the second side of the image source layer. The parallax barrier comprises an array of transparent spots. The image source layer comprises at least one clear spot and is configured to emit light away from the parallax barrier. The electromechanical system comprises one or more mirrors pivotably mounted and controllable to reflect light towards the at least one clear spot in the image source layer.
