Compounds, and polymers thereof, useful dopants for light emitting diodes and light emitting display devices are disclosed. The compounds have the following structure Formula 1: wherein R, R, R, R, L, L, L, L, a, b, c and d are as defined herein. Light emitting diodes including compounds of Formula 1 (and polymers thereof, i.e., compounds of Formula 3), light emitting devices including the same as well as methods associated with preparation and use of such compounds, polymers and devices are also provided.

Organic compound, and light-emitting diode and light-emitting device including the same

An inorganic light emitting diode in which at least one energy control layer including an organometallic compound interacting with a hydroxyquinoline moiety is disposed between an emitting material layer and at least one charge transfer layer and an inorganic light emitting device including the diode are disclosed. An exciton recombination zone is formed at the central region in the EML, and inorganic luminescent particles have minimal surface defects by introducing the energy control layer. The inorganic light emitting diode and the inorganic light emitting device can improve their color purity and luminous efficiency.

Inorganic light emitting diode and inorganic light emitting device including the same

The present disclosure is directed to quantum dots comprising a core-shell structure and a novel arrangement of ligands thereon. Light emitting diodes including the quantum dots, light emitting devices including the same as well as methods associated with preparation and use of such compounds and devices are also provided.
