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: 2017-01-09

OLEDs containing a stacked hybrid architecture including a phosphorescent organic emissive unit and two fluorescent organic emissive units are disclosed. The stacked hybrid architecture includes a plurality of electrodes and a hybrid emissive stacked disposed between at least two of the electrodes. The stack contains at least three emissive units and at least two charge generation layers. At least one of the three emissive units is a phosphorescent organic emissive unit and at least two of the three emissive units are fluorescent organic emissive units. More specifically, the two fluorescent organic emissive units may be blue organic emissive units that emit light from the same or different color regions.

Patent
Universal Display Corporation | Date: 2017-05-31

A method for improving the operation of an OLED includes maximizing on-radiative transfer of excited state energy from the OLEDs organic emissive material to surface plasmon polaritons in an enhancement layer by providing the enhancement layer no more than a threshold distance away from the organic emissive layer; and emitting light into free space from the enhancement layer by scattering the energy from the surface plasmon polaritons through an outcoupling layer that is provided proximate to the enhancement layer but opposite from the organic emissive layer.
