Paper Abstract

BlackScreen rear-projection display screens, developed by Jenmar Visual Systems of Fremont California are well suited for cockpit avionics applications primarily because they exhibit both high image resolution and high ambient light rejection. These characteristics combine to produce a high- contrast image on these screens, even in very brightly lit viewing environments. On-screen optical noise commonly referred to as graininess or speckle, can often be a problem in rear-projection systems. These image artifacts appear as grainy patches in the image that move with the field-of-view of the observer and are most visible in the near field (i.e., approximately 12 to 24 inches from the screen). This paper will describe the methods we are using to characterize these artifacts in BlackScreen. Our testing uses a range of projection systems and characterization methods. We will also describe our approach to reduce these artifacts, and will illustrate that approach with engineering data.
