A time-sequential autostereoscopic three-dimensional (3D) display using a set of cylindrical optical elements (COEs) as the backlight steering is proposed. The operation principle of the system and its detailed design are described. In our system, the COEs control the direction of the backlight for the proposed system of the user's right and left views. Additionally, the displayed images can be observed under ambient lighting by implementing the high density light-emitting diode (LED) arrays. Compared to the first-generation array display, the image resolution is greatly improved by the addition of the time multiplexing technique. A prototype system using a set of COEs, LED arrays, two linear Fresnel lenses, and an elliptical diffuser is constructed. Here, the directional backlight beams are synchronized with the right and left images alternately displayed on the liquid crystal display (LCD) screen, and two convergent viewing zones are formed alternately in front of the user's eyes; then 3D images are perceived because of persistence of the vision of human eye. The experimental results show that the proposed method is a potential technology for 3D applications such as 3D television.
提出了一种使用一组圆柱形光学元件（COE）作为背光转向的时间序列自动立体三维（3D）显示器。描述了该系统的工作原理及其详细设计。在我们的系统中，COE为用户的左右视图所提出的系统控制背光的方向。此外，通过实现高密度发光二极管（LED）阵列，可以在环境光下观察显示的图像。与第一代阵列显示器相比，通过添加时间复用技术，图像分辨率得到了极大提高。构建了一个使用一组COE、LED阵列、两个线性菲涅耳透镜和一个椭圆形漫射器的原型系统。在这里，定向背光束与交替显示在液晶显示器（LCD）屏幕上的左右图像同步，并且在用户眼前交替形成两个会聚观察区；然后由于人眼视觉暂留而感知到3D图像。实验结果表明，该方法是一种用于3D电视等3D应用的潜在技术。
