Electronic liquid crystal display environments and military specifications

摘要

Abstract: The Liquid Crystal Display provides a necessary information interface to pilots from their aircraft and equipment. In order to successfully complete mission requirements, increased amounts of information are made available to pilots. The control of commercial and military air transports, weapons systems and ordinance that contain the highest technology electronics requires pilots to have instant access to large amounts of data. Mechanical dials and 'steam gauges' alone do not have the capability to provide that data. Operational readiness comes with a need for all display systems to have the utmost availability, reliability and maintainability. Original specifications developed from the initial use of smaller fixed format liquid crystal displays have been reproduced over the years with little specification maintenance or attention to actual environmental demands that may or may not have been apparent with mechanical dials (white paint on black dials). As the Liquid Crystal Display grows increasingly important in the aircraft, the need for improved reliability increases. The examples that follow will suggest that further definition is needed on exactly how and where the displays are to be used, and in what environments they will be required to survive. With cooperative efforts of among equipment designers, display designers, and specification writers, new and updated specifications targeted directly for liquid crystal display systems will help to achieve cost effective, high reliability information display systems for users.!23
