An organic light emitting display can be integrated with a touch screen panel, in which control lines arranged in the touch screen panel are used as driving electrodes of a mutual capacitive touch screen panel, and a signal applied to the control lines in a touch recognition operation is input in synchronization with the signal applied to a display panel without having influence on the display. The control lines used as driving electrodes of the touch screen panel can be electrically connected to auxiliary lines arranged close to sensing electrodes of the touch screen panel, thereby improving touch recognition sensitivity.
