Abstract: In a method of driving a display apparatus, an outside illuminance is sensed by an illuminance sensor. At least one first color subpixel of a plurality of first color subpixels is disabled. Remaining first color subpixels are enabled based on the sensed outside illuminance. The first color subpixels corresponding to a first color are arranged along a first direction and a second direction crossing the first direction. An image is displayed on the remaining enabled first color subpixels.

Abstract: A light emitting device may include a first electrode, a first light emitting stack disposed on the first electrode, a charge generation layer disposed on the first light emitting stack, a second light emitting stack disposed on the charge generation layer, and a second electrode disposed on the second light emitting stack. Each of the first light emitting stack and the second light emitting stack includes a hole transport layer. A hole mobility of the charge generation layer is lower than a hole mobility of the hole transport layer.
