SUNLIGHT VIEWABLE ELECTROLUMINESCENT DISPLAYS MILITARY APPLICATION

A new advanced type of high ambient viewing AC Electroluminescent display has been developed incorporating a combination of high contrast and high brightness techniques. The improvement in the contrast is achieved by a black absorption layer within the thin film structure. Improvement in the brightness is attributed to increasing the refresh rate by an order of magnitude. This can only be accomplished by an order of magnitude decrease in front electrode impedance with the use of a new metalized structure to reinforce the ITO electrodes and lower their resistance.
