On 18 September 1998, Optical Imaging Systems (OIS) of Northville, MI ceased production of Active Matrix Liquid Crystal Display (AMLCD) modules due to financial losses and the lack of a clear and immediate path to making the company profitable. Lack of OIS AMLCD modules has threatened to delay production delivery of aircraft to the US Air Force, Navy and Army. Other vendors make similar modules, but in most cases there is no interchangeable module immediately available. Consequently, military Program Offices and their contractors are working to overcome the present shortage. This paper discusses the non-standard parts/diminishing manufacturing sources problem and assesses various strategies that might be needed to prevent programs from being so dependent on unique sole-source devices in the future. It also suggests a list of display sizes and types that are good candidates for wide application and are thus less sensitive to events like the closing of one component manufacturer.
