Abstract
A light emitting device package includes a first light emitting diode pixel, the first light emitting diode pixel including first light emitting diode chips that each emit light, and a first pixel driving integrated circuit under the first light emitting diode chips of the first light emitting diode pixel, the first pixel driving integrated circuit configured to drive the first light emitting diode chips based on an active matrix scheme, in which each of the first light emitting diode chips is driven using an entire one frame interval, and based on a pulse width modulation scheme, in which a time during which each of first driving currents is applied to a respective one of the first light emitting diode chips is controlled within the entire one frame interval.
