Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication devices, such as smartphones and tablets, primarily display two-dimensional images, which are less immersive than three-dimensional images, and existing 3D technologies require complex setups like 3D glasses or multiple projectors, making it difficult to achieve widespread use, especially for multiple users viewing from different perspectives.
Innovation Solution
A stereoscopic image display system that includes an autostereoscopic display coupled with a computing platform, user tracking unit, and sensor network, which tracks user positions and renders three-dimensional images using a rotating autostereoscopic display to provide immersive 3D experiences for single or multiple users without the need for additional equipment like 3D glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional 3D display technologies are used, then 3D imaging capability is achieved, but device complexity increases due to requirements for multiple projectors, AR headgear, or 3D glasses
Solution Approach 1:
The patent extracts and removes the need for external 3D viewing equipment (glasses, headgear) by integrating the 3D display functionality directly into the screen itself through electrophoretic liquid crystal technology, allowing the screen to present different images to different eyes without additional components
Solution Approach 2:
The electrophoretic liquid crystal display serves multiple functions: it can display 2D images, autostereoscopic 3D images, and dynamically adjust between different viewing perspectives, eliminating the need for separate devices for different display modes
2Adaptability or versatility
If multiple users view from different perspectives simultaneously, then viewing flexibility is improved, but system complexity increases due to need for multiple projectors or complex tracking systems
Solution Approach 1:
The display system dynamically adjusts the electrophoretic liquid crystal orientation in real-time based on detected user positions and eye locations, allowing multiple users to view from different angles simultaneously without fixed viewing zones or complex mechanical adjustments
Solution Approach 2:
The system uses sensors to detect user positions and eye locations, then feeds this information back to the display controller which adjusts the liquid crystal orientation accordingly, creating a closed-loop system that adapts to multiple users automatically
3Ease of operation
If 3D images are projected without specialized equipment, then ease of operation is improved, but image quality and immersion deteriorate compared to systems with multiple projectors or AR headgear
Solution Approach 1:
The patent replaces complex mechanical projection systems (multiple projectors, moving mirrors) with an electrophoretic liquid crystal display that uses electrical fields to control light orientation, achieving 3D display without mechanical moving parts while maintaining high image quality
Solution Approach 2:
The system changes the optical parameters of the liquid crystal molecules through electrical control, adjusting their orientation to direct light at different angles for different eyes, thereby creating stereoscopic depth perception without additional optical components

AI summary
According to one implementation, a stereoscopic image display system includes a computing platform having one or more hardware processor(s), a system memory storing a software code, an autostereoscopic display, and a user tracking unit controlled by the hardware processor(s). The hardware processor(s) execute the software code to utilize the user tracking unit to detect a left eye location and a right eye location of a user of the stereoscopic image display system, and to determine a left eye image and a right eye image corresponding to an output image of a content being played out by the stereoscopic image display system based on the respective left eye location and right eye location of the user. The hardware processor(s) further execute the software code to render the left eye image and the right eye image using the autostereoscopic display to generate a three-dimensional (3D) image of the output image.
