Abstract: The present disclosure relates to an organic light emitting diode and an organic light emitting device including the same. The organic light emitting diode includes a first electrode; a second electrode facing the first electrode; and a first blue emitting material layer including a first compound and a second compound and positioned between the first and second electrodes, wherein the first compound is represented by Formula 1, and the second compound is represented by Formula 3. According to an aspect of the present disclosure, it is allowed to provide an OLED and an organic light emitting device having high emitting efficiency and/or improved lifespan.

Abstract: An electronic device and method for providing sound user interface is provided. The electronic device includes a display circuit configured to display at least one object, an audio circuit configured to reproduce sound, and a processor electrically connected to the display circuit and the audio circuit. The processor is configured to configure virtual space coordinates for the at least one object, match a sound source to the at least one object, set a sound effect for the sound source based on the virtual space coordinates, and reproduce the sound source using the set sound effect.
