Abstract: An organic light emitting device (OLED) comprises an anode; a cathode; and a light emitting layer, disposed between the anode and the cathode; wherein the light emitting layer comprises at least one luminescent compound; and wherein the transition dipole moment of the at least one luminescent compound is oriented parallel to the surface of the light emitting layer. A method of fabricating a light emitting layer, comprises the steps of providing a substrate; depositing less than 2 nm of a template material on the substrate; and depositing a composition comprising at least one light emitting compound on the template material.

Abstract: Disclosed are methods, designs and materials for extending the device operational lifetime of the phosphorescent organic light emitting devices (OLEDs) such as thermally activated delayed fluorescence (TADF) OLEDs. Applying a graded cohost or co-doped emission layer (EML) in the organic layers, both charge transport and charge balance can be precisely engineered to generate a uniform exciton/exciplex profile, preventing the early deaths due to the dense hot-excited states in the device. This invention is aimed at the short lifetime problem of the high efficient phosphorescent OLEDs and TADF OLEDs, especially in the white, blue and deep blue applications.

Abstract: A semi-freestanding drapery extension beam comprising (i) two vertical side supports each having a ground-engaging end and a ceiling-engaging end; (ii) a top beam having its ends connected between the ceiling-engaging ends of the side supports; and (iii) a drapery slot extending along the length of said top beam. Additionally, support brackets can be implemented between the top beam and each vertical side support to hold the top beam in position and help it support a vertical load. A sheer clip and tie back hooks can also be implemented to increase the aesthetic beauty of the drapes hung from the inventive beam. Finally, the beam is easily folded for storage or transport. In another embodiment of the present invention, the two vertical side supports are used without a transverse top beam. Again, this allows the use of vertically adjustable tie back hooks without damaging the surrounding walls.
