    Abstract: A compound of Formula I: wherein ring A is a 5-membered or 6-membered aromatic ring; wherein RA, RB, and RC each independently represent mono to the maximum allowable substitution, or no substitution; wherein Y1 is absent or present, and when present is selected from the group consisting of a direct bond, O, S, Se, CRR′, NR, SiRR′, and BR; wherein each X1-X3 is N or CR; wherein at least one of X1-X3 is N; wherein each A1-A5 is independently C or N; wherein the maximum number of N atoms that can connect to each other within each ring is two; wherein each R1, R2, R3, and R4 is independently selected from the group consisting of alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, aryl, heteroaryl, and combinations thereof; wherein each R, R′, RA, RB, and RC is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and wherein any two substituents may be joined or fused together to form a ring.

    Abstract: Heteroleptic compounds having a structure of Ir(LA)p(LB)q(LC)r, where LB and LC are different bidentate ligands, p is 1 or 2, q is 1 or 2, r is 0, 1, or 2, and ligand LA has a structure of Formula I, In Formula I, moiety B is a monocyclic or polycyclic fused ring system; each of X1 to X6 is C or N; each RA, RB, and RC is independently a hydrogen or a general substituent; at least one RB comprises a partially or fully deuterated alkyl or cycloalkyl group; if moiety B is phenyl, at least two adjacent RC substituents are fused to form a ring, with the proviso that at least one LB or LC is present and is not a phenylpyridine-based ligand. Formulations, OLEDs, and consumer products containing the same are also disclosed.

    IPC: H01L51/00

    Abstract: Embodiments of the disclosed subject matter provide a device having a substrate, and a plurality of unit areas of an organic light emitting diode (OLED) display disposed on the substrate. The unit areas may be repeating, area-filling subdivisions on the substrate that each have an anode and a cathode. The organic film may be disposed over portions of the device other than the unit areas. The device may include at least one pixel having a plurality of sub-pixels disposed within each of the plurality of unit areas. The cathode of at least one pixel of each of the plurality of unit areas may be a common cathode.

    Abstract: An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum.

    IPC: H01L27/32

    Abstract: This disclosure relates to reduced power consumption OLED displays at reduced cost for reduced information content applications, such as wearable displays. Image quality for wearable displays can be different than for high information content smart phone displays and TVs, where the wearable display has an architecture that in includes, for example, an all phosphorescent device and/or material system that may be fabricated at reduced cost. The reduced power consumption can facilitate wireless and solar charging.
