Claim 13:
14. A light-emitting display device comprising:
a display panel including a first potential power voltage line, a second potential power voltage line and a plurality of pixels each including a driving transistor and an organic light-emitting diode; a controller configured to generate at least one sensing image in a sensing mode; and a sensing unit configured to sense a voltage or current of the first potential power voltage line for each panel or for each region in the display panel in a state in which 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 a display mode, and the high potential current to the high potential power voltage line of the display panel in the sensing mode.
