PLAN VIEW DISPLAY (PVD) BACKGROUND LIGHTING

Controllers at air route traffic control centers (ARTCC's) have complained that display information on plan view displays (PVD's) causes eyestrain and headaches after a prolonged period of controlling traffic. The controllers indicated that background brightness level similar to the type previously experienced for raster-scanned displays might be a remedy. Therefore, an investigation and evaluation of several methods of generating a uniform background brightness on the PVD were conducted. Results show that the defocused raster method is the most effective and practical type of background brightness generation to be considered for field evaluation. The etched-surface cathode-ray tube also tended to produce a more uniform background illumination than most techniques investigated. This report is a survey of several methods to generate a uniform background brightness on the face of a plan view display (PVD) in an air route traffic control center (ARTCC). The background brightness is intended to offset the undesirable PVD characteristics of high contrast and front surface reflections, which is annoying to the vision of the air traffic controlers.
