A compound having a Formula of Ir(L A ) x (L B ) y (L C ) z , where each of x and y is independently 1 or 2, z is 0 or 1 or 2, and x+y+z=3. In Formula Ir(L A ) x (L B ) y (L C ) z , L A includes a structure of Formula I, L B includes a structure of Formula II, L C is a bidentate ligand; each of X 1 to X 25 is C or N; Y is a linking group; L o is a direct bond or a linking group; L is a direct bond or an organic linker; each of moieties A, D, and F is a monocyclic ring or a polycyclic fused ring system; and each substituent is independently H or a General Substituent defined herein. Formulations, OLEDs, and consumer products containing the compound are also provided.

Devices, pixel arrangements, and fabrication techniques thereof are provided for devices that include pixels having red, green, and blue sub-pixels, where the blue sub-pixel is shared among more than one pixel in the arrangement. The display includes fewer than three data lines per pixel and uses only three colors of sub-pixel.

A compound including a first ligand L A of Formula I, is disclosed. In Formula I, ring B is a 5- or 6-membered ring; X 1 , X 2 , and X 3 are each CR A or N; R is a 5- or 6-membered carbocyclic or heterocyclic ring, which can be further fused or substituted; and (1) when ring B is an unfused 6-membered ring, X 1 and X 2 are N, and X 3 is C; and (2) when ring B is a fused 6-membered ring, ring B has the structure of Formula II, In this structure, the wavy line indicates the point of connection to ring A; Q 1 to Q 6 are each C or N; and, when proviso (2) applies, (I) at least one of X 1 , X 2 , and X 3 is N; or (II) R is two or more fused or unfused 5- or 6-membered carbocyclic or heterocyclic rings, or (III) at least ring A or R is substituted with a partially or fully deuterated alkyl or partially or fully deuterated cycloalkyl group.

Organic electroluminescent devices are provided, including devices having an emissive layer in addition to an outcoupling layer with material having an emissive state. The material having an emissive state within the outcoupling layer converts the energy confined in the multipolar localized surface plasmon resonance modes to dipolar emissive modes, thereby increasing the light outcoupling efficiency of devices.

Organic emissive devices are provided that include host structures with electron and/or hole transporting components having specific energy levels that promote good charge balance and enhanced charge capture. The disclosed energy level structures provide host systems that reduce exciplex formation and thereby promote improved device internal quantum efficiency and stability, or which intentionally include exciplex formation so as to modify the average orientation of the dipole.

Provided are organometallic compounds having Formula I: Also provided are formulations including these organometallic compounds. Further provided are OLEDs and related consumer products that utilize these organometallic compounds.

Provided are compounds having a first ligand L A of Formula I Also provided are formulations comprising these compounds. Further provided are OLEDs and related consumer products that utilize these compounds.

Novel compounds comprising heteroleptic iridium complexes are provided. The compounds have a particular combination of ligands which includes a single pyridyl dibenzo-substituted ligand. The compounds may be used in organic light emitting devices, particularly as emitting dopants, to provide devices having improved efficiency, lifetime, and manufacturing.

A first device including a first organic light emitting device is provided. The first OLED includes an anode; a cathode; and a first emissive layer, disposed between the anode and the cathode, comprising a first emissive dopant that is a phosphorescent metal compound having an emission peak wavelength between 530 nm to 580 nm. The first device also includes a second emissive layer that includes a fluorescent compound, a phosphorescent compound, or both; and the first device is capable of emitting white light.
