Universal Display Corporation is a leader in developing and delivering organic light emitting diodes technologies, materials and services to the display and lighting industries. It is also an OLED research company, and one of the field's pioneers. Founded in 1994, the company currently owns or has exclusive, co-exclusive or sole license rights with respect to more than 3,000 issued and pending patents worldwide for the commercialization of phosphorescent based OLEDs and also flexible, transparent and stacked OLEDs - for both display and lighting applications. Based in Ewing, New Jersey, with international offices in Ireland, South Korea, Hong Kong, Japan and Taiwan, Universal Display works and partners with a network of organizations, including Princeton University, the University of Southern California, the University of Michigan, and PPG Industries, Inc. Its phosphorescent OLED technologies and materials are licensed and supplied to companies such as Samsung, LG, AU Optronics CMEL, Pioneer, Panasonic Idemitsu OLED lighting and Konica Minolta. UDC is working with many other companies, including Sony, DuPont and Novaled. Back in 2009 UDC claimed that "virtually All AMOLEDs on the market use our technology".Popular Tech site 'Gizmodo' writer Andrew Tarantola says "I have seen the future of high definition displays and lo, it is glorious. Not to mention rollable, foldable, and clearly superior to LCD/LED—really every other panel technology available today." Wikipedia.

Patent
Universal Display Corporation | Date: 2017-01-04

The present invention is directed to a compound comprising a triphenylene core of Formula F:._(1) is a non-fused aryl group, having one or more substituents R_(a), wherein each substituent R_(a) is selected from a non-fused aryl or heteroaryl, a branched or straight chain of non-fused aryls or heteroaryls, and alkyl substituted aryl or heteroaryl group.


Patent
Universal Display Corporation | Date: 2017-03-22

The present invention is directed to a device comprising a first organic light emitting device that emits light having a peak wavelength in the visible spectrum of 600 - 700 nm, further comprising a first emissive layer having a first emissive material, wherein the first emissive material is phosphorescent; a second organic light emitting device that emits light having a peak wavelength in the visible spectrum of 500 - 600 nm, further comprising a second emissive layer having a second emissive material, wherein the second emissive material is phosphorescent; a third organic light emitting device that emits light having a peak wavelength in the visible spectrum of 400 - 500 nm, further comprising a third emissive layer having a third emissive material, wherein the third emissive material is phosphorescent; and a fourth organic light emitting device that emits light having a peak wavelength in the visible spectrum of 400 to 500 nm, further comprising a fourth emissive layer having a fourth emissive material, wherein the fourth emissive material is phosphorescent; wherein the peak wavelength in the visible spectrum of light emitted by the fourth organic light emitting device is at least 4 nm less than the peak wavelength in the visible spectrum of light emitted by the third organic light emitting device.


Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.


Patent
Universal Display Corporation | Date: 2016-06-22

This invention discloses heteroleptic iridium complexes containing two tridentate ligands with three five- and one six-cyclometalated rings, showing desired device performance properties.


Patent
Universal Display Corporation | Date: 2016-06-03

Devices, components and fabrication methods are provided for improving the efficiency of OLED displays. An outcoupling component such as a microlens array (MLA) is attached to an OLED, with a relatively small distance between the MLA and the OLED. Cross-talk and back scattering are reduced by the use of colored lenses, focusing layers, and other methods.


Patent
