20110065282 | APPARATUS AND METHODS TO FORM A PATTERNED COATING ON AN OLED SUBSTRATE - An apparatus for applying a patterned coating to an OLED substrate in a continuous roll-to-roll vapor based deposition process is provided comprising a vapor deposition source, a processing drum, a drive roller, and a shadow mask wherein the shadow mask comprises a mask line feature that selectively prevents deposition of the coating onto the substrate. Also presented is a method for applying the coating. | 03-17-2011 |
20110086183 | BARRIER COATING WITH REDUCED PROCESS TIME - The present techniques provide systems and methods for protecting electronic devices such as organic light emitting devices (OLEDs) from adverse environmental effects using a thin film encapsulation with reduced process time. In some embodiments, the process time of forming a graded barrier over the OLED structure may take less than 5 minutes, and may result in substantially similar barrier properties as those of metal and epoxy sealants and/or typical thin film encapsulations. The process time of forming the barrier may be reduced by increasing deposition rates for organic and/or inorganic materials, reducing the thicknesses of organic and/or inorganic layers, and/or varying the number of zones in the barrier. | 04-14-2011 |
20110151200 | EDGE SEALING METHOD USING BARRIER COATINGS - The present techniques provide systems and methods for protecting electronic devices, such as organic light emitting devices (OLEDs) from adverse environmental effects. The edges of the devices may also be protected by a edge protection coating to reduce the adverse affects of a lateral ingress of adverse environmental conditions. In some embodiments, inorganic materials, or a combination of inorganic and organic materials, are deposited over the device to form a edge protection coating which extends approximately 3 millimeter or less beyond the edges of the device. In other embodiments, the device may be encapsulated with an organic region, and with an inorganic region, or the device may be encapsulated with inorganic materials, which may form the edge protection coating and may be combined with ultra high barrier technology. The coatings formed over the device may extend beyond the edges of the device to ensure lateral protection. | 06-23-2011 |
