Abstract
An organic light emitting display apparatus includes an organic light emitting display panel including a display area, including a transparent area and an opaque area, and a non-display area, a gate driver sequentially supplying a gate pulse to a plurality of gate lines included in the organic light emitting display panel, and an initialization unit transferring gate pulses and/or initialization control signals, output from the gate driver, to a plurality of transparent area gate lines. A camera photographing a region in a forward direction with respect to the organic light emitting display panel is provided in the transparent area of a rear surface of the organic light emitting display panel. A first pixel driving circuit provided in the transparent area includes two transistors, and a second pixel driving circuit provided in the opaque area includes at least three transistors.
