Numerical simulation of the displayed image on the entire screen of autostereoscopic displays

Abstract

A three-dimensional simulation model calculating the optical intensity distribution for the entire screen of an autostereoscopic display at a given eye position was developed in this study. A parallax barrier array was used for the optical model and reverse ray tracing of light from the observer's eye to the subpixels through the slits of the barrier was performed based on reverse geometrical optics. By investigating the optical behavior of the displayed image for the nine-view design condition for various viewing distances, we found the inhomogeneous crosstalk from the unwanted views and predicted segmented images which were comprised of multiple images from different views on the entire display screen. From the results, our simulation model shows good potentiality for predicting the displayed image on the entire display screen of autostereoscopic displays for various positions of the observer's eye with sufficient calculation speed.

A Real-Time Super Multiview Rendering Pipeline for Wide Viewing-Angle and High-Resolution 3D Displays Based on a Hybrid Rendering Technique

“…The viewpoint mask as input data is a 2D buffer that records the viewpoint arrangement of the SMV 3D display. The relationship between the viewpoint number v kl and the subpixel index (k, l) can be represented by the following equation [39], [40]…”

P‐88: Numerical Simulation and Quantitative Evaluation for Motional Display Uniformity in a Directional Backlight Glasses‐free 3D Display

“…To quantify this display deterioration, a visualized simulation based on ray-tracing model is proposed in this article [2], [3] . The reverse ray tracing from observers' eyes to the backlight array through the optical element is performed based on the geometrical optics [4] . Then the optical intensity distribution on the screen is obtained after confirming the relation between backlight units and reverse rays.…”

Ground autostereoscopic display with new type non-uniform barrier

“…2 is the simulation result by the use of the reference [5] approach when the eye position is (0,0,2.5m). The table 1 is to show the simulation parameters which have the same physical meaning as in the reference [6]. As is depicted in Fig.…”

“…However, the displays devices can't be compatible with the traditional autostereoscopic display images [5]. So this paper presents a nine-view large size ground autostereoscopicdisplayand its associated barrier generating methods based on reverse ray tracing technique [6] [7].…”
