多视差图像的阶梯屏障技术克服了传统视差屏障系统仅在水平方向上每幅图像的图像质量恶化的问题。阶梯屏障将分辨率问题分配到水平和垂直方向。该系统结构简单，由平板显示器和台阶屏障组成。阶梯屏障的孔径不是条纹，而是呈阶梯状排列的微小矩形，并且每个图像的子像素具有相同的排列。并提出了适用于计算机图形学和真实图像的系统的三种图像处理方法。随后，开发了两种类型的3D显示器：22英寸型号和50英寸型号。 22英寸型号采用3840 x 2400像素的超高清液晶显示屏。视差图像数量为7个，一幅图像的分辨率为1646 x 800。50英寸型号在1280 x 768像素的等离子显示面板上有四个观察点。它可以提供立体动画，一幅图像的分辨率为960 x 256像素。此外，还开发了结构或电气2D 3D兼容系统。
The step barrier technology with multiple parallax images has overcome the problem of conventional parallax barrier system that the image quality of each image deteriorates only in the horizontal direction. The step barrier distributes the resolution problem both to the horizontal and the vertical directions. The system has a simple structure, which consists of a flat-panel display and a step barrier. The apertures of the step barrier are not stripes but tiny rectangles that are arranged in the shape of stairs, and the sub-pixels of each image have the same arrangement. And three image processes for the system applicable to computer graphics and real image have been proposed. Then, two types of 3-D displays were developed, 22-inch model and 50-inch model. The 22-inch model employs a very high-definition liquid crystal display of 3840 x 2400 pixels. The number of parallax images is seven and the resolution of one image is 1646 x 800. The 50-inch model has four viewing points on the plasma display panel of 1280 x 768 pixels. It can provide stereoscopic animations and the resolution of one image is 960 x 256 pixels. Moreover, the structural or electric 2-D 3-D compatible system was developed.
