We describe a device which has the potential to be used both as a virtual image display and as a backlight. The pupil of the emitted light fills the device approximately to its periphery and the collimated emission can be scanned both horizontally and vertically in the manner needed to illuminate an eye in any position. The aim is to reduce the power needed to illuminate a liquid crystal panel but also to enable a smooth transition from 3D to a virtual image as the user nears the screen.
我们描述了一种既可用作虚拟图像显示器又可用作背光源的设备。所发射光的光瞳大致充满该设备直至其周边，并且准直发射光可以按照照亮处于任何位置的眼睛所需的方式进行水平和垂直扫描。目的是降低照亮液晶面板所需的功率，同时当用户靠近屏幕时能够实现从3D到虚拟图像的平滑过渡。
