    Abstract: A compound comprising a first ligand LA of Formula I or Formula II: wherein A1 and A2 are each independently C or Si; wherein each RA, and RB independently represents mono to the maximum allowable substitution, or no substitution; wherein each X1, X2, and X3 is independently C or N; wherein each R, R1, R2, R3, R4 and RA is independently a hydrogen or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, boryl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; wherein LA is complexed to a metal M; wherein M is optionally coordinated to one or more other ligands; wherein the ligand LA is optionally linked with the one or more other ligands to form a tridentate, tetradentate, pentadentate, or hexadentate ligand; and wherein any two substituents are optionally joined or fused together to form a ring.

    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.

    Abstract: A region of a device is provided that includes a first material and a second material. The first and second materials may be co-dopants of an emissive material or region. The first material may have an energy gap of not more than about 100 meV between the first excited singlet state and the first excited triplet state. Excitons that transition to the T1 state can be activated to the S1 state due to the relatively small energy gap. This thermal activation process is fast enough that non-radiative decay from the T1 state to the S0 state is minimal or negligible, thus allowing for sensitization up to and including 100%. The second material may be a phosphorescent-capable material, and may act as a sensitizer to the first material.

    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 translation: 公开了允许驱动三个或更少的四个或更多个子像素发射原始颜色信号的像素分量的布置。 可以将原始颜色信号的第一投影投影到两个子像素的颜色空间上。 然后可以将第一投影投影到对应于第三像素的颜色空间的第二投影上。 可以基于第二投影来驱动第三像素，可以基于被驱动的第三像素来驱动剩余的至少三个子像素中的两个。

    Abstract translation: 提供了包括第一材料和第二材料的装置的区域。 第一和第二材料可以是发光材料或区域的共掺杂剂。 第一材料可以具有在第一激发单态和第一激发三线态之间不超过约100meV的能隙。 由于相对较小的能量间隙，转变到T1状态的激子可以被激活到S1状态。 这种热激活过程足够快，使得从T1状态到S0状态的非辐射衰减是最小的或可忽略的，从而允许高达100％的敏化。 第二种材料可以是具有磷光的材料，并且可以充当第一材料的敏化剂。
