This paper describes the system tradeoffs related to display type, resolution, and pixel structure, taking examples from the development of binary and grayscale high resolution AMLCDs. Performance is related to the match achieved between the Human Visual System (HVS), the display system and the task assigned, The Active Matrix Liquid Crystal Display (AMLCD) is compared to other technologies at the high acuity levels achieved in a 282 Dots per Inch (DPI) monochrome grayscale and a 141 Color Groups per inch (CGI) color grayscale AMLCD. The potential benefits to military aviators of very high resolution displays are outlined as well as the challenges to implement these systems.
