Today's cockpit integrator, whether for state of the art military fast jet, or piston powered general
aviation, is striving to utilize all available panel space for AMLCD based displays to enhance
situational awareness and increase safety. The benefits of a glass cockpit have been well studied and
documented. The technology used to create these glass cockpits, however, is driven by commercial
AMLCD demand which far outstrips the combined worldwide avionics requirements. In order to
satisfy the wide variety of human factors and environmental requirements, large area displays have
been developed to maximize the usable display area while also providing necessary redundancy in case
of failure. The AMLCD has been optimized for extremely wide viewing angles driven by the flat
panel TV market. In some cockpit applications, wide viewing cones are desired. In bubble canopy
cockpits, however, narrow viewing cones are desired to reduce canopy reflections. American Panel
Corporation has developed AMLCD displays that maximize viewing area, provide redundancy, while
also providing a very narrow viewing cone even though commercial AMLCD technology is employed
suitable for high performance AMLCD Displays. This paper investigates both the large area display
architecture with several available options to solve redundancy as well as beam steering techniques to
also limit canopy reflections.

American Panel Corporation (APC) designs and delivers customized AMLCD products for aircraft cockpits and rugged ground vehicles. APC specifies AMLCD's to be designed and manufactured, based on an exclusive relationship, with both LG.Philips LCD, in South Korea and BOE Hydis, in South Korea. This paper addresses the Fringe Field Switching (FFS) technology developed by BOE Hydis and APC's customization of this technology into both high end avionics display products as well as consumer display products. FFS technology optimizes all optical and electrical performance qualities into a single product. APC offers the high temperature FFS products for all applications.
American Panel Corporation (APC) is the world's leader of customized AMLCD's for use in all rugged applications including aircraft, and ground vehicles. Previously, the AMLCD that has been designed and manufactured to APC specification by LG.Philips LCD in South Korea required the addition of a heater, EMI shield, and temperature sensors in order to meet the demands of the cockpit and tank. APC now introduces the first AMLCD products in which the heater, EMI shield, and temperature sensors are integrated into the AMLCD itself.
American Panel Corporation in Alpharetta Georgia and LG-Philips-LCD in Seoul South Korea have a strategic alliance for the design and manufacture of custom AMLCD products targeted for the military vehicle and avionics sector. As part of this relationship, new innovations in AMLCD technology specifically aimed at the rugged and avionics applications have been developed and are now brought to the marketplace
The APC- LG-LCD relationship continues to expand with new products developed specifically for APC applications and also LG-LCD products developed for the consumer market, but adapted using APC enhancements for applications in the rugged world. Our delivery performance has proven that a superior, cost effective product can only be produced by incorporating product enhancements at the point of AMLCD manufacture. Further adaptations for specific applications can be simplified by utilizing the same part number panel for multiple platform uses. The manufacturing environment must be flexible enough to run multiple part numbers on a weekly basis. As such, manufacturing automation implemented at APC continues to strengthen our position as the world leader in custom AMLCD display modules. These automation initiatives are the direct result of APC learning the LG-LCD manufacturing method and applying these principals to our particular processes. The APC - LG-LCD relationship affords availability guarantees for display modules for a period of 10 years, thereby reducing procurement risk and minimizing costs associated with redesign when using consumer driven panels. This guarantee redefines the game rules for procurement of AMLCD's. We also offer a very quick turn for those customers who prefer to perform a lifetime buy of product. Typically, thousands of panels can be delivered within six months of a production go ahead. The APC -LC-LCD team remains successful due to the many years spent working together to develop and manufacture products that this niche market demands. The mutual respect for the technical and manufacturing operations at APC and LG-LCD continues to foster a relationship that time and again deliver superior, cost effective products to the market.
