Claim 0:
1. A light-emitting display device comprising:
a controller operating in a display mode and a sensing mode;
a display panel including a plurality of pixels each including a driving transistor and an organic light-emitting diode and displaying at least one sensing image in the sensing mode; and
a sensing unit configured to sense an electrical physical quantity for each panel or for each region in the display panel when the at least one sensing image is displayed on the display panel,
wherein the sensing unit includes a voltage/current converter for converting a high potential power voltage into a high potential current, and
wherein the sensing unit supplies the high potential power voltage to a high potential power voltage line of the display panel in the display mode, and the high potential current to the high potential power voltage line of the display panel in the sensing mode.
