Abstract

Active Matrix Liquid Crystal Displays (AMLCDs) are being called upon to operate in environments which are increasingly harsh. The displays studied in this paper were originally designed for an environment from -55 to +85 degree(s)C. Open (bubble canopy) cockpits expose the displays to extremely high solar loads in some environments. This paper presents a summary of modeling techniques used to predict maximum AMLCD temperatures under F/A-18E/F aircraft storage conditions. Results from testing of displays and polarizer lamination test samples in these predicted environments are also presented. The development test process resulted in significant improvements and the identification of other issues which need to be resolved before AMLCDs can be guaranteed to be truly durable in these environments.
