MULTIUSER PERSONALLY DISTRIBUTING LC DISPLAY AND PROJECTION DEVICE WITH A CONTROLLED REFRACTION OF THE LIGHT BEAM ON THE BASIS OF LIQUID CRYSTALS WITH INHOMOGENEOUS DISTRIBUTION OF THE DIRECTOR

Abstract

The task of an indicator LCD device (display) is solved, which allows a significant number of users to simultaneously view individually different visuals on the same display surface. Viewers, adjusting the parameters of an individual video stream interactively, can be users of a multi-user computer with a single visual information surface instead of a set of individual displays. The device can be used in cockpits of airplanes with a multi-crew, displaying for the crew members individually different information. Similarly, the device can be employed in other multi-local control systems, as well as in information acquisition and processing systems. A projection device in which the number of controlled optical elements is two orders of magnitude smaller than the number of pixels in the (projected) image is developed, which reduces the cost of the equipment. Design solutions for a battery projector with improved energy efficiency of projection are proposed.
