OLED display packaging method for harsh military environment extremes

Organic light emitting diode (OLED) technology for improved panel displays (e.g. navigation, integrated bridge systems, etc.) is widely recognizing as the brighter, thinner, lighter, lower power, more water tight, less expensive, and faster than the active matrix liquid crystal display (AM-LCD). In order to realize OLED, significant advancements have to be made in display device efficiency and packaging technology to withstand the maritime environment extremes such as shock, vibration, salt, water, high and low temperatures. New Span Opto-technology Inc. proposes a novel white light emitting OLED display having partially conjugated poly(phenylenevinylene) (PPV) polymer and polydimethylsiloxane (PDMS) encapsulation system to endure the harsh environmental conditions. Our innovative packaging idea using PDMS encapsulation will overcome the harsh marine environmental barriers including shock, vibration, temperature extremes, and salt water and will be compatible with requirements for Night Vision Imaging System such as sunlight readable, low power consumption, and wide view angle. Total system weight and fabrication cost of this novel OLED display device would be dramatically reduced when compared to conventional AM-LCD displays or currently used hermetic sealed OLED displays. We will demonstrate a bright single-layer white OLED device and test its reliability to meet military standard environmental specification (MIL-STD-810D) requirements.
