Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current volumetric 3D display simulation methods using ideal stereo pixel points fail to accurately replicate the real display effect, making it difficult to achieve a realistic simulation and efficiently debug manufacturing parameters for volumetric 3D display devices.
Innovation Solution
The method involves acquiring display variables for a virtual 3D display screen with stereo pixels that include voxel parameters in three directions, determining display state parameters based on structure and display data, and simulating the display by considering the size, rotation, and phase plane attributes of the stereo pixels, which allows for a more realistic simulation by incorporating actual pixel sizes and dynamic display timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ideal stereo pixel points are used for simulation, then the simulation model is simple, but the display effect accuracy deteriorates
Solution Approach 1:
The patent changes the parameters of stereo pixels from ideal point coordinates to actual volumetric pixels with specific sizes in three directions (width, height, depth). By modifying these geometric parameters, the simulation transitions from a simplified point-based model to a realistic volume-based model that accounts for the physical dimensions of display pixels, thereby improving display effect accuracy while maintaining manageable model complexity
Solution Approach 2:
The patent creates a virtual display screen that copies the actual physical structure of the volumetric 3D display device, including the true sizes and spatial arrangements of stereo pixels. This virtual copy incorporates real manufacturing parameters and pixel geometries, allowing the simulation to replicate actual display effects including grainy phenomena, rather than using idealized point representations
2Measurement precision
If actual pixel sizes and dynamic display timing are incorporated, then the simulation accuracy improves, but the computational complexity increases
Solution Approach 1:
The patent transitions from two-dimensional point coordinates to three-dimensional volumetric pixels with dimensions in width, height, and depth directions. This dimensional expansion allows the simulation to account for the actual physical size of pixels and their spatial occupation, improving accuracy by modeling how pixels of finite size interact with displayed objects in 3D space
Solution Approach 2:
The patent incorporates dynamic display timing parameters including display duration ratios and phase plane transition timings. These dynamic parameters allow the simulation to model the temporal aspects of volumetric display operation, such as how long pixels remain active and how phase planes transition, making the simulation more representative of actual device behavior without requiring overly complex computational models
