    Abstract: Emissive layer structures for organic emissive devices and emissive devices containing such structures are provided. The emissive layer includes one or more sub-layers or similar regions. A fluorescent emitter and two compounds that may form an exciplex are distributed within the sub-layers so as to enhance Forster transitions from the exciplex to the fluorescent acceptor and suppress undesirable Dexter transitions from the exciplex to the fluorescent acceptor.

    Abstract: Arrangements of pixel components that allow driving three or less of four or more sub-pixels to emit an original color signal are disclosed. A first projection of the original color signal may be projected onto the two sub-pixel's color space. The first projection may then be projected onto a second projection corresponding to the color space of a third pixel. The third pixel may be driven based on the second projection only two of the remaining at least three sub-pixels may be driven based on the third pixel being driven.

    Abstract: A compound that includes a ligand LA of Formula I, the ligand LA coordinated to a metal M wherein X1 to X11 are each independently selected from CRA or N; RA, RB, and RC independently represent mono to the maximum possible substitution, or no substitution; wherein at least one of RA, RB, or RC is selected from the group consisting of wherein X12, X13, X14, and X15 are independently selected from CRD or N, and two of X12, X13, X14, or X15 are N; with the proviso that R1 and R2, and R3 and R4, do not join to form a fused benzene ring; and wherein the metal M is selected from the group consisting of Ir, Rh, Re, Ru, Os, Pt, Au, Ag, and Cu, and ligand LA is optionally linked to another ligand to form a tridentate, tetradentate, pentadentate, or hexadentate ligand. A compound of Formula VI. The invention is also directed to an OLED that includes an organic layer that comprises a compound of Formula I or Formula VI, and a consumer product that includes the described OLED.
