Dual Liquid Crystal Flat Panel Display

There are a growing number of scenarios where remote equipment and vehicles must be operated in environments unsafe for human presence. Ideally the remote vision system should mimic physical presence as much as possible. Steadily, the demand for stereoscopic (3D) viewing increases, in order to preserve depth of field information, and to ‘immerse’ the operator as much as possible in the scenario. In Phase II several 3D displays, based on Phase I designs, will be produced. The 3D display uses two liquid crystal display (LCD) panels stacked on top of one another. On the first panel two stereo images are superposed. The second panel encodes the two images in polarization. Finally the viewer’s polarized glasses decode the images to produce a stereoscopic view. The 3D displays constructed in Phase II will be fully integrated. A small custom electronics and image processing board will be developed in Phase II to take 2 video inputs and convert them to the drive signals for the two LCD panels. All the components for the 3D display will be integrated into a single attractive and rugged housing that accepts two video inputs and is driven with a 12 or 24 V power source.
