    Abstract: A light-emitting element of the present invention can have sufficiently high emission efficiency with a structure including a host material being able to remain chemically stable even if a phosphorescent compound having higher emission energy is used as a guest material. The relation between the relative emission intensity and the emission time of light emission obtained from the host material and the guest material contained in a light-emitting layer is represented by a multicomponent decay curve. The relative emission intensity of the slowest component of the multicomponent decay curve becomes 1/100 for a short time within a range where the slowest component is not interfered with by quenching of the host material (the emission time of the slowest component is preferably less than or equal to 15 ?sec); thus, sufficiently high emission efficiency can be obtained.

  • Patent number: 9812511
    Abstract: An electroluminescent display or lighting product incorporates a panel including a collection of distinct light-emitting elements formed on a substrate. A plurality of distinct local seals are formed below respective individual light-emitting elements or groups of light-emitting elements. Some embodiments combine a metal foil substrate and glass local seals in a flexible bottom-emitting product. The local seal may be used in conjunction with a continuous thin film encapsulation structure. Optical functions can be provided by each local seal, including refraction, filtering, color shifting, and scattering. Each local seal is formed by depositing a low melting temperature glass powder suspension or paste using inkjet technology, and fusing the glass powder using a scanning laser beam having a tailored beam profile. In other embodiments, a lower encapsulation substrate incorporating local window seals is wholly or partially pre-formed.

  • Patent number: 9812662
    Abstract: A light-emitting element of the present invention can have sufficiently high emission efficiency with a structure including a host material being able to remain chemically stable even if a phosphorescent compound having higher emission energy is used as a guest material. The relation between the relative emission intensity and the emission time of light emission obtained from the host material and the guest material contained in a light-emitting layer is represented by a multicomponent decay curve. The relative emission intensity of the slowest component of the multicomponent decay curve becomes 1/100 for a short time within a range where the slowest component is not interfered with by quenching of the host material (the emission time of the slowest component is preferably less than or equal to 15 ?sec); thus, sufficiently high emission efficiency can be obtained.

  • Patent number: 9805925
    Abstract: In electrodeless HID lamps the radio frequency (RF) source is separated from a lamp housing in which vessel containing plasma arc is mounted. This lamp housing is usually designed to maximize the amount of RF energy incident on the plasma arc. The plasma arc, however, cannot convert the entire amount of incident RF energy into light and a portion instead is released as propagating radiation or remains localized RF electromagnetic fields in the vicinity of lamp. In this invention, we introduce field suppression probes: Small, configurable structures that are made of conductive materials that mount directly to the lamp housing or alternately the lamp fixture that is able to suppress unused RF energy that is emanated from the lamp housing or plasma. These probes, when configured with the lamp, can substantially suppress the unused RF energy and prevent EMI emissions and reduce RF feedback that can adversely affect the lamp.
