Quantification of Specular Image Distinction in Avionics Active Matrix Liquid Crystal Display (AMLCD) Applications

摘要

With the proliferation of liquid crystal displays as the primary instrumentation interface on aircraft flight decks, it becomes important to quantify and control the unique optical parameters, associated with AMLCDs, that affect readability in a critical environment. It has been discovered that image distinctness, in addition to reflected energy intensity, can be a significant detriment to display readability. Consequently, efforts are being made to establish measurement procedures and quantify distinctness-of-image to help control the detrimental effects of this characteristic. Two measurement methods will be discussed that are currently being considered for use in describing the degree of specular distinctness-of-image reflections on avionics AMLCDs.
