高密度定向显示器可以通过使用定向射线投影大量定向图像来产生自然的三维（3-D）图像。当定向光线的角度间距为0.2度（类似于0.4度）时，通过3D空间中的点的多于两个的定向光线同时进入观看者的眼睛，使得观看者的眼睛可以聚焦在该点上。在会聚功能和调节功能之间没有出现差异，从而显示器不会引起视觉疲劳。提出了两种不同的系统配置：投影配置和薄配置。一个原型显示的投影配置的基础上构建。原型显示器显示64个定向图像，其中定向射线具有0.34度的水平角间距。屏幕尺寸为9.2英寸。初步实验结果表明，观众可以专注于原型显示器产生的3D图像。
A high-density directional display can produce natural three-dimensional (3-D) images by projecting a large number of directional images using directional rays. When the angle pitch of the directional rays is 0.2 degrees similar to 0.4 degrees, more than two directional rays passing through a point in 3-D space enter the viewer's eye simultaneously so that the viewer's eye can focus on that point. No discrepancy appears between the convergence function and the accommodation function so that the display does not induce visual fatigue. Two different system configurations are presented: a projection configuration and a thin configuration. A prototype display based on the projection configuration was constructed. The prototype display displayed 64 directional images with directional rays having a horizontal angle pitch of 0.34 degrees. The screen size was 9.2 in. The preliminary experimental results showed that a viewer could focus on 3-D images produced by the prototype display.
