Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autostereoscopic 3D image display devices have limited viewing angles and suffer from jitter due to non-continuous adjustments in spectroscopic devices and gray values when users move, restricting user positioning and display performance.
Innovation Solution
A method and system that track user positions to dynamically adjust the display units' gray values based on calculated distances and widths, using a combination of tracking, determination, calculation, and display control modules to ensure continuous adjustment and smooth 3D image rendering across wider angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tracking technology is used in combination with dynamic adjustable spectroscopic devices to expand display angle, then viewing angle is improved, but device complexity and hardware requirements increase
Solution Approach 1:
The patent replaces dynamic mechanical adjustment of spectroscopic devices with a computational approach. Image processing algorithms dynamically adjust gray values of display units based on tracked user position, eliminating the need for mechanically adjustable spectroscopic components while achieving the same wide-angle autostereoscopic effect
Solution Approach 2:
The patent changes the operational parameters of fixed display units by dynamically adjusting gray values in response to user position. This parameter-based control achieves adaptive viewing angle expansion without requiring physical reconfiguration of spectroscopic devices
2Stability of the object's composition
If spectroscopic device and gray value are adjusted continuously in real-time based on user position, then jitter is reduced, but processing complexity increases
Solution Approach 1:
The patent implements continuous adjustment of gray values for display units as the user moves within the viewing zone. This continuous modification of display parameters ensures smooth transitions and eliminates jitter without requiring complex mechanical systems
Solution Approach 2:
The system uses real-time user position tracking feedback to dynamically adjust gray values. This closed-loop control ensures the display remains stable and jitter-free by continuously adapting to user movement
3Device complexity
If fixed gray values are used in autostereoscopic 3D display, then device complexity is reduced, but viewing angle remains limited and jitter occurs when user moves
Solution Approach 1:
The patent transforms the static gray value configuration into a dynamic system where gray values are continuously adjusted based on user position. This dynamic approach enables wide-angle viewing and eliminates jitter while maintaining relatively simple hardware

AI summary
A wide-angle autostereoscopic three-dimensional (3D) image display method is provided. The method includes tracking a user in an autostereoscopic 3D image viewing state with respect to a display panel including a plurality of display units, obtaining a first distance between the display panel and a spectroscopic unit array including a plurality of spectroscopic units and a first width associated with each spectroscopic unit, and determining a second distance between a viewing position of the user and the display panel. The method also includes determining a width of a display unit combination corresponding to the second distance. Further, the method includes calculating a gray value of each display unit based on the width of the display unit combination and a reference value of the distance between each display unit and an edge of the display unit combination and displaying the 3D image on the display panel.
