Specifically, a novel thin-film layer structure using vacuum deposition will demonstrate negligible moisture permeation (<5 x 10-7 g/m2/day) under 85 degrees C and 85% RH. The reduction in moisture permeation will significantly improve device life. It is generally agreed upon in the OLED community that OLEDs on flexible substrates or on roll-to-roll substrates require, at a minimum, moisture permeation rate of < 10-6 g/m2/day. A measurement of the permeation rate before demonstration on live OLED devices (to be conducted during the Phase I option) will significantly reduce cost and time in establishing the efficacy of the thin-film layer structures. Eliminating the dessicant materials and the additional process steps required by current sealant technologies will reduce manufacturing costs. Benefits: Potential applications include cockpit displays, command console displays, field-ready HMDs, camcorders and cameras, personal communications devices, windshield and automotive displays, and personal HMDs. A robust, highly transmissive thin-film encapsulation based on low-temperature, plasma enhanced chemical vapor deposition (PECVD), combined with other encapsulation techniques, will effectively preserve conformance while eliminating the porosity of the film. The design will require no desiccant. Such an encapsulation will improve the device lifetime by effectively eliminating moisture permeation through the seal. Since the encapsulation is based on thin-film deposition, the technique can be easily scalable to large substrate sizes and even to flexible substrates and roll-to-roll manufacturing. OLED displays with the advanced sealant technology will be manufacturable on existing production lines. The resultant displays can be used in both direct-view and near-to-eye head-mounted displays (HMDs). Return
