Abstract: Electronic devices that use desiccants for protection from moisture. The electronic devices comprise a substrate and an organic element disposed over the top surface of the substrate. The substrate has one or more voids which may store desiccants. The voids may penetrate partially or completely through the thickness of the substrate. An environmental barrier is disposed over the organic element and the voids. Also provided are methods for making electronic devices that use desiccants.

Abstract: Heteroleptic compounds containing phenylpyridine and phenylbenzimidazole are provided. The compounds may be used in organic light emitting devices, particularly as emissive dopants in the emissive layer of such devices.

Abstract: Novel compounds containing a triphenylene moiety linked to an ?? connected binaphthyl ring system are provided. These compounds have surprisingly good solubility in organic solvents and are useful as host compounds in red phosphorescent OLEDs.

Abstract: A single-step method of making tetradentate platinum or palladium complexes is disclosed. The method advantageously allows the formation of a platinum or palladium complex in a single step, even with sterically hindered ligands, without the use of highly reactive intermediates. The compounds made by the disclosed method are useful in OLED applications.

Abstract: The present invention provides organoselenium compounds comprising dibenzoselenophene, benzo[b]selenophene or benzo[c]selenophene and their uses in organic light emitting devices.

Abstract: Novel phosphorescent platinum complexes containing tetradentate ligands are provided. The disclosed compounds have three 6-membered metallocycle units in each tertadentate ligand. The disclosed compounds have desirable electronic properties that make them useful when incorporated into a variety of OLED devices.

Abstract: A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, it cathode and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material, that includes nanocrystals. The phosphorescent emissive dopant is bonded to the host material by a bridge moiety.

Abstract: A circuit for a pixel in a display device includes drive circuitry, an organic light emitting diode in electrical connection with the drive circuitry, and at least one resistive current path which is selected to be non-emissive in electrical connection with the drive circuitry and in parallel with the organic light emitting diode.

Abstract: The invention provides a light emitting device, comprising: a first electrode; a second electrode; a light emitting layer disposed between the first electrode and the second electrode, wherein the light emitting layer comprises an emitting material having a first triplet energy level (T1); and an exciton quenching layer disposed between the light emitting layer and the second electrode, wherein the exciton quenching layer comprises a non-emitting quenching material having a second triplet energy level (T1); wherein the exciton quenching layer is disposed adjacent to the light emitting layer; wherein the emitting material emits by phosphorescence or delayed fluorescence; and wherein the first triplet energy level (T1) is higher than the second triplet energy level (T1). Methods of making the same are also provided.
