The presentation deals with some applications of OLED displays in military optronic systems, which are
scheduled by SAGEM DS (Defence and Security).
SAGEM DS, one of the largest group in the defence and security market, is currently investigating OLED
Technologies for military programs. This technology is close from being chosen for optronic equipment such as
future infantry night vision goggles, rifle-sight, or, more generally, vision enhancement systems. Most of those
applications requires micro-display with an active matrix size below 1". Some others, such as, for instance,
ruggedized flat displays do have a need for higher active matrix size (1,5" to 15"). SAGEM DS takes advantages
of this flat, high luminance and emissive technology in highly integrated systems. In any case, many
requirements have to be fulfilled: ultra-low power consumption, wide viewing angle, good pixel to pixel
uniformity, and satisfactory behaviour in extreme environmental conditions....
Accurate measurements have been achieved at SAGEM DS on some micro display OLEDs and will be detailed:
luminance (over 2000 cd/m2 achieved), area uniformity and pixel to pixel uniformity, robustness at low and high
temperature (-40°C to +60°C), lifetime.
These results, which refer to military requirements, provide a valuable feedback representative of the state of the
art OLED performances.
