Claim 11:
12. The display apparatus of claim 11, wherein the specific voltage comprises a first specific voltage and a second specific voltage respectively applied to gate terminals of the first and second driving transistors in a constant current generator circuit sensing period, and a third specific voltage and a fourth specific voltage respectively applied to the gate terminals of the first and second driving transistors in a PWM circuit sensing period, and
wherein the sensing unit is configured to:
while the first transistor is turned on in the constant current generator circuit sensing period, sense a first current flowing in the first and second driving transistors based on the first and second specific voltages, and output first sensing data corresponding to the sensed first current, and
while the first transistor is turned on in the PWM circuit sensing period, sense a second current flowing in the first and second driving transistors based on the third and fourth specific voltages, and output second sensing data corresponding to the sensed second current.
