    Abstract: A display apparatus includes a substrate including a display area, a peripheral area surrounding the display area, a function-adding area, of which at least a portion is surrounded by the display area, and a detour area disposed between tine display area and the function-adding area. The display apparatus includes a plurality of pixel circuits disposed in the display area. A plurality of driving lines are electrically connected to the pixel circuits and extend in a direction in the display area. A first detour line is disposed in the detour area and is electrically connected to a first driving line. A second detour line is disposed in the detour area. The second detour line is electrically connected to a second driving line and is disposed in a different layer from the first detour line.

    Abstract: An organic light emitting display device includes pixel driving circuits to control pixels which include organic light emitting diodes. The pixel driving circuits include a first pixel driving circuit and a second pixel driving circuit, and the organic light emitting diodes include a first organic light emitting diode. The first organic light emitting diode emits light at a first brightness based on a driving current from the first pixel driving circuit in a first frame, and emits light at a second brightness based on a driving current from the second pixel driving circuit in a second frame.
