Subjective Image Quality Comparisons of AMLCD and CRT Implementations ofElectronic Flight Formats

摘要

This report discusses the methods and results of a study which compared theuseability of proposed electronic flight formats presented a Cathode Ray Tube (CRT) to the same formats presented on an Active Matnx Liquid Crystal Display (AMLCD). Eight subject pilots performed a series of flying tasks in two simulator sessions: one with a commercial grade CRT and the other with a commercial grade, prototype AMLCD. Subjective assessments were obtained via questionnaires that addressed image quality and useability issues. The results showed that the display formats that were developed and tested on a CRT could be implemented on the test AMLCD hardware with no significant degradation in image quality or useability. Some considerations for optimizing formats for AMLCD implementations are discussed.
