Optimization of the polyplanar optical display electronics for a monochrome B-52 display
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 new 200 mW green solid-state laser (10,000 hr. life) at 532 nm as its light source. To produce real-time video, the laser light is being modulated by a Digital Light Processing (DLP{trademark}) chip manufactured by Texas Instruments (TI). 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{trademark}) chip is operated remotely from the Texas Instruments circuit board. In order to achieve increased brightness a monochrome digitizing interface was investigated. The operation of the DMD{trademark} divorced from the light engine and the interfacing of the DMD{trademark} board with the RS-170 video format specific to the B-52 aircraft will be discussed, including the increased brightness of the monochrome digitizing interface. A brief description of the electronics required to drive the new 200 mW laser is also presented.
