Abstract
The following paper presents a summary of flight demonstration results on dichroic liquid crystal displays (LCDs) subjected to over one year field use in harsh continental US fielded conditions. The LCD modules were subjected to actual solar loading to test for UV and mechanical damage that resulted in void formation in the liquid crystal. White spots or gas bubbles that appeared as white areas in the black background of a dichroic liquid crystal display were observed. This presentation is based on the original presentation of Electronic Liquid Crystal Display Environments and Military Applications for SPIE AeroSense '95, Cockpit Displays session. Conclusions form 1995 will be briefly reviewed and compared to results of fielded units as well as the results of the laboratory testing on samples utilizing LCD technologies. The time frame for the field demonstration data will include up to the date of the paper submission and will cover a minimum of 14 months of field use. The original concerns of the end user and the major results of the analysis of the dichroic LCDs after voids were found in less than one year of original deployment will be reviewed. The field demonstration took place in the weapons system that showed the highest incident of voids over that deployment period, and second weapon system under identical field use. Data was collected on equal numbers of units of original configuration and improved configuration LCD modules in weapons system deployment in the southwestern US.
