描述了一种用于视频电话的眼睛接触显示器和摄像机系统，其中摄像机通过传统的有源矩阵LC显示器观看。通过从显示器移除后偏振器，相机可以透过显示器观看，而看不到显示器上的信息。显示器/摄像机多路复用和颜色通过偏振投影照明系统实现。三色组通过LCD投射到PDLC快门上，该快门充当可切换屏幕。
An eye-contact display and camera system for video telephony is described in which a video camera looks through a conventional active matrix LC display. By removing the rear polarizer from the display, the camera can look through the display without seeing the information on the display. Display/camera multiplexing and color are achieved via a polarized projection illumination system. Color triads are projected through the LCD onto a PDLC shutter that acts as a switchable screen.
