    Abstract: A patterned roller, and a method of making the patterned roller, is provided. A patterned roller may be made by first forming a first mold having a negative pattern by etching pits in a flat mold surface with an etching process. Then, a second mold is formed having a positive pattern, by pouring a first curable material into the first mold, curing the first curable material, and removing the first curable material from the first mold. Then the patterned roller having the negative pattern is formed by coating a roller with a layer of a second curable material, pre-curing the second curable material to provide a viscous but not hardened surface, and rolling the roller over the second mold to create the negative pattern in the second curable material. The second curable material is then cured. Any of the curable materials may be coated after curing, preferably with metal, to reduce sticking in subsequent steps. The patterned roller may be used to create a pattern of microlenses in a third curable material. A substrate is coated with the third curable material. The patterned roller is rolled over the third curable material to transfer the pattern to the third curable material. The third curable material may then be cured.

    Abstract translation: 提供了图案化辊，以及制造图案辊的方法。 可以通过用蚀刻工艺在平坦模具表面中蚀刻凹坑来首先形成具有负图案的第一模具来制造图案化辊。 然后，通过将第一可固化材料倒入第一模具中，固化第一可固化材料，并从第一模具中除去第一可固化材料，形成具有正图案的第二模具。 然后，具有负图案的图案辊通过用一层第二可固化材料涂覆辊来形成，预先固化第二可固化材料以提供粘性但不硬化的表面，以及将辊滚动到第二模上以产生 第二可固化材料中的负图案。 然后固化第二可固化材料。 任何可固化材料可以在固化之后，优选用金属涂覆，以减少后续步骤中的粘附。 图案化辊可用于在第三可固化材料中产生微透镜图案。 用第三可固化材料涂覆基材。 图案化辊在第三可固化材料上滚动以将图案转移到第三可固化材料。 然后可以固化第三可固化材料。

    Abstract: An OLED may include regions of a mineral having a refractive index less than that of the substrate, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED.

    Abstract: A method of fabricating an organic film is provided. A non-reactive carrier gas is used to transport an organic vapor. The organic vapor is ejected through a nozzle block onto a cooled substrate, to form a patterned organic film. A device for carrying out the method is also provided. The device includes a source of organic vapors, a source of carrier gas and a vacuum chamber. A heated nozzle block attached to the source of organic vapors and the source of carrier gas has at least one nozzle adapted to eject carrier gas and organic vapors onto a cooled substrate disposed within the vacuum chamber.
