Abstract: An organic light diode (OLED) and an organic light emitting device comprising the OLED (e.g., a display device or a lighting device) are described. The OLED can comprise at least one emitting material layer including a first compound where an alkyl group is substituted to a specific position of an electron donor moiety and a second compound of a boron-based fluorescent material. Luminous properties in the OLED and the device can be improved as excitons generated at the first compound are transferred efficiently to the second compound.

Abstract: Embodiments relate to a quantum rod composition, a quantum rod film, a display device with a quantum rod film, and a method of forming a quantum rod film. The quantum rod film includes a plurality of quantum rods and a polymer with a dipole side chain. Responsive to an external electric field, the major axis of the quantum rods and an axis of the dipole side chain arranges in the same direction. The display device includes a plurality of pixel and common electrodes for generating an electric field, and a backlight unit positioned under a first substrate. Responsive to receiving light from the backlight unit, the quantum rod film emits light polarized in a direction parallel to the major axis of the quantum rods.
