Hardware/Software Functional Control Method of Microdisplay Modules for Personal Video-Projection Systems

Abstract

The hard and software functional control method of microdisplay modules for personal video projection systems is presented. The main part of the complex is Video Pattern Generator (VPG 170), which allows creating test image fields with different parameters and characteristics. As a microdisplay module, either an active matrix SVGA microdisplay made using LCoS technology or a test module of a light-emitting type based on a Schottky nanoporous Silicon / Aluminium was used, whose operation is controlled visually. A special optical system has been developed, including a polarizating cube with antiglare coatings and RGB backlit system operated by a controller. The control of the generator test VPG 170 signals is accomplished using a specially developed software installed in a PC using Windows XP operating system.
