Touchscreen Display Enhancements for Flight Deck Applications

Touchscreen displays are of growing interest to the aerospace community and are having a significant impact on how pilots interact with avionics. With the right hardware construction and software algorithm, a touchscreen display can manage and present information and controls to the pilot in an intuitive manner. This paper describes a hardware touchscreen rationale, primarily focusing on the lighting performance of a touchscreen display modified for flight deck applications. Specifically, we describe a durable glass-on-film-on-glass resistive touchscreen display with improved high ambient contrast ratio (HACR) properties and a low friction, lipophobic textured front-surface that disrupts the distinctiveness of reflective images.
