Claim 11:
12. A method of driving a display device, the method comprising:
sensing a first current of at least one first pixel row of a display panel in a first frame period;
sensing a second current of the first pixel row in a second frame period after the first frame period when the first current is greater than or equal to a first threshold value;
determining whether the first pixel row is burnt;
stopping a supply of a power voltage to the display panel when the first pixel row is burnt;
sensing a third current of at least one second pixel row of the display panel adjacent to the first pixel row in a third frame period after the second frame period when the second current is greater than or equal to the first threshold value, and
wherein determining whether the first pixel row is burnt includes determining that the first pixel row is burnt when the third current is greater than a second threshold value.
