Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing free-space 3D displays face issues such as limited view angle, low resolution, brightness, scene distortion, and high cost, which hinder their effectiveness in providing an immersive viewing experience for multiple users without the need for head-mounted displays.
Innovation Solution
A superstereoscopic display system incorporating a light source, parallax generator, and high-index optical volume, which enables angle-dependent viewing by using lenticular lenses and polarizers to create a continuous unbroken scene, enhancing off-angle separation and perceived depth, while also allowing for multiple perspectives and adaptive image processing based on viewer position and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free-space 3D displays are implemented without HMD, then multiple users can share the viewing experience, but the view angle is limited and scene distortion occurs
Solution Approach 1:
The display system segments the viewing space into multiple angular zones, each optimized for specific viewing angles. The parallax generator divides the light field into distinct directional components, allowing different users at different positions to see optimized images without mutual interference, thereby reducing scene distortion while maintaining multi-user capability
Solution Approach 2:
The patent transitions from traditional 2D display to 3D light field display by adding angular dimension. The high-index optical volume creates a three-dimensional light distribution space where light rays are directed at different angles to multiple users simultaneously, eliminating scene distortion through proper angular separation
2Measurement precision
If conventional stereoscopic displays are used, then depth perception is achieved, but off-angle separation is poor and view angle is limited
Solution Approach 1:
The patent applies local quality by optimizing optical properties at different angular positions. The high-index optical volume has spatially varying refractive properties that enhance off-angle separation specifically where needed, while maintaining good on-axis performance for accurate depth perception
Solution Approach 2:
The system changes optical parameters (refractive index, angular distribution) across different viewing zones. By varying these parameters locally, the display achieves both precise depth perception for on-axis viewers and enhanced off-angle separation for users at peripheral positions
3Stability of the object's composition
If high-index optical volume is introduced, then off-angle separation is enhanced, but device complexity increases
Solution Approach 1:
The patent merges the high-index optical volume with the existing parallax generator and display elements into an integrated optical system. This consolidation reduces overall device complexity by eliminating separate components while maintaining the off-angle separation enhancement benefits
