Patent number: 11844230Abstract: An OLED lighting device comprising: a blue light-emitting unit with a blue-light fluorescent, phosphorescent or TADF emitter; a yellow light-emitting electroluminescent unit comprising a green phosphorescent emitter, a red phosphorescent emitter and at least one non-emitting host; wherein the blue light-emitting unit and the yellow light-emitting unit are separated by a mixed interlayer with two non-emitting charge-carrier materials. Desirably, the yellow-light emitting unit essentially consists of a green phosphorescent emitter, a red phosphorescent emitter and a single non-emitting host. The mixed interlayer desirably has more than 50% of a hole-transporting material and an electron-transporting material. The Triplet Energy of both materials in the mixed interlayer can be higher than the Triplet Energies of the R and G phosphorescent dopants.Type: GrantFiled: February 10, 2021Date of Patent: December 12, 2023Assignee: OLEDWorks LLCInventors: Jeffrey Spindler, Marina Kondakova

Patent number: 10923689Abstract: A method for making an OLED lighting panel is disclosed. A patterned inorganic insulating layer is used to enclose an area over a first electrode layer leaving portions of the first electrode layer and substrate adjacent to the outside of the enclosure exposed. After uniform deposition of the organic layer(s), the organic layer(s) are selectively removed over the inorganic insulating layer and an adjacent portion of the substrate to form a sealing region. After uniform deposition of the second electrode, the enclosed area is encapsulated and any overlying layers over the first and second electrodes outside the enclosed area are removed resulting in an OLED within the enclosed area with electrode contact pads outside the enclosed area. The OLED can be manufactured at low cost with no or limited use of shadow masking and is suitable for roll-to-roll processes.Type: GrantFiled: January 18, 2019Date of Patent: February 16, 2021Assignee: OLEDWorks LLCInventors: John Hamer, Jeffrey Spindler
