| 20090191342 | METHOD FOR EDGE SEALING BARRIER FILMS - Methods of making an edge-sealed, encapsulated environmentally sensitive device. One method includes providing an environmentally sensitive device with a contact on a substrate; depositing a decoupling layer adjacent to the environmentally sensitive device, the decoupling layer having a discrete area and covering the environmentally sensitive device and not covering the contact, the decoupling layer deposited using a printing process; depositing a first barrier layer adjacent to the decoupling layer, the first barrier layer having a first area greater than the discrete area of the decoupling layer, and the first barrier layer having a second area covering the decoupling layer and the contact, the decoupling layer being sealed between the edges of the first barrier layer and the substrate or an optional second barrier layer; and removing the second area of the first barrier layer from the contact. | 07-30-2009 |
| 20090208754 | METHOD FOR EDGE SEALING BARRIER FILMS - A method of making an edge-sealed, encapsulated environmentally sensitive device. The method includes providing an environmentally sensitive device on a substrate; depositing a decoupling layer through one mask, the decoupling layer adjacent to the environmentally sensitive device, the decoupling layer having a discrete area and covering the environmentally sensitive device; increasing the distance between the one mask and the substrate; and depositing a first barrier layer through the one mask, the first barrier layer adjacent to the decoupling layer, the first barrier layer having an area greater than the discrete area of the decoupling layer and covering the decoupling layer, the decoupling layer being sealed between the edges of the first barrier layer and the substrate or an optional second barrier layer. | 08-20-2009 |
| 20090209760 | ORGANOMETALLIC COMPLEXES AS PHOSPHORESCENT EMITTERS IN ORGANIC LEDS - Organic light emitting devices are described wherein the emissive layer comprises a host material containing an emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes. The organic light emitting devices optionally contain an exciton blocking layer. Furthermore, improved electroluminescent efficiency in organic light emitting devices is obtained with an emitter layer comprising organometallic complexes of transition metals of formula L | 08-20-2009 |
| 20100187988 | TRANSPARENT CONTACTS FOR ORGANIC DEVICES - A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure. The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias. The devices are substantially transparent when de-energized, making them useful for heads-up display applications. | 07-29-2010 |
| 20100193468 | METHOD FOR EDGE SEALING BARRIER FILMS - An edge-sealed, encapsulated environmentally sensitive device. The device includes an environmentally sensitive device, and at least one edge-sealed barrier stack. The edge-sealed barrier stack includes a decoupling layer and at least two barrier layers. The environmentally sensitive device is sealed between an edge-sealed barrier stack and either a substrate or another edge-sealed barrier stack. A method of making the edge-sealed, encapsulated environmentally sensitive device is also disclosed. | 08-05-2010 |
| 20110059259 | Method and System for High-Throughput Deposition of Patterned Organic Thin Films - High-throughput OVJP systems and methods are provided that may use multiple flow paths having different conductances to enable deposition with relatively short lag times. A high-throughput OVJP system may include a flow tube having a cross-sectional area much larger than the diameter of one or more apertures through which source material may be expelled during deposition. Use of such a configuration may allow for deposition with reduced lag times. | 03-10-2011 |
| 20110062462 | Novel Device Structure - Organic light emitting devices are provided having multiple subpixels. An organic spacer layer is provided in at least one subpixel to protect the emissive layer of the at least one subpixel from overspray due to the deposition of a different emissive layer in a nearby subpixel. More generally, a first device is provided, where the first device comprises a multicolor organic light emitting device. The first device may be the multicolor organic device itself. Or, the first device may be a larger device, such as a consumer device, that includes one or many of the multicolor organic devices. The multicolor organic light emitting, device further comprises multiple subpixels. In the most general case, there are at least a first subpixel and a second subpixel. | 03-17-2011 |
