Abstract

The polyplanar optical display (POD) is a unique display screen which can be used with any projection source. The prototype ten inch display is two inches thick and has a matte black face which allows for high contrast images. The prototype being developed is a form, fit and functional replacement display for the B-52 aircraft which uses a monochrome ten-inch display. In order to achieve a long lifetime, the new display uses a 100 milliwatt green solid- state laser at 532 nm as its light source. To produce real- time video, the laser light is being modulated by a digital light processing (DLP) chip manufactured by Texas Instruments. In order to use the solid-state laser as the light source and also fit within the constraints of the B-52 display, the digital micromirror device (DMD) circuit board is removed from the Texas Instruments DLP light engine assembly. Due to the compact architecture of the projection system within the display chassis, the DMD chip is operated remotely from the Texas Instruments circuit board. We discuss the operation of the DMD divorced from the light engine and the interfacing of the DMD board with various video formats including the format specific to the B-52 aircraft. A brief discussion of the electronics required to drive the laser is also presented.
