Abstract

In this paper, we present an autostereoscopic display system with wide-dynamic-range view zone, high brightness and switchable 2D/3D. For this purpose, we propose a novel directional backlight system inspired by an optical splitter. Combined with eye tracking technique and LED-lit matrix, we expand the viewing zone and achieve 2D/3D switchable properties. And the design of direct illumination-type LED backlight improves the brightness significantly. The mathematical analysis and logic principle of the system is provided in this paper. And also, we build an autostereoscopic display prototype by the directional backlight system, and demonstrate experimentally that our system gives the viewer freedom both of viewing position and viewing environment with images of high quality.

具有宽动态视野区、高亮度和可切换2D/3D的定向背光3D显示系统

本文提出了一种具有宽动态范围视场、高亮度和可切换2D/3D的自动立体显示系统。为此，我们提出了一种受分光器启发的新型定向背光系统。结合眼动追踪技术和LED照明矩阵，我们扩展了观看区域，实现了2D/3D可切换特性。直接照明型LED背光的设计使亮度得到显著提高。本文给出了系统的数学分析和逻辑原理。此外，我们还通过定向背光系统构建了一个自动立体显示器原型，并通过实验证明，我们的系统为观看者提供了观看位置和观看环境的自由度，并提供了高质量的图像。
