Disclosed is an electroluminescent display device integrated with image sensors, including: a display panel having a plurality of pixels; a display panel driving circuit configured to write data of an input image into the pixels during a display mode so as to display the input image with the pixels; and a sensor processing circuit configured to apply a reverse bias to Organic Light Emitting Diodes (OLEDs) disposed in at least some of the pixels during a sensor mode so as to process sensor signals received from the pixels.
