摘要： An organic light emitting display apparatus includes an organic light emitting display panel including a display area having a transparent area and an opaque area, and a non-display area. A gate driver is configured to sequentially supply a gate pulse to a plurality of gate lines included in the organic light emitting display panel. An initialization circuit is configured to transfer gate pulses or initialization control signals, output from the gate driver, to a plurality of transparent area gate lines. A camera is configured to photograph a region in a forward direction with respect to the organic light emitting display panel, and the camera may be 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 may differ from a second pixel driving circuit provided in the opaque area.
