Paper Abstract

A light valve has been developed that is suitable for high performance video projection display applications. This device uses a chalcogenide photoconductor in a resistive mode switching configuration. Resolutions of greater than 1000 lines and video rate response times have been shown. Optical isolation of greater than 107 and contrast ratios of 75:1 have been achieved. This paper also addresses the application of the light valve to a projector.
