Abstract: A method includes setting a first reference voltage, a second reference voltage lower than the first reference voltage and higher than a panel default voltage, and a reference current, applying the first reference voltage to the pixels, obtaining a first measurement current by measuring a current of the display panel generated in response to the first reference voltage, comparing the first measurement current with the reference current, obtaining a second measurement current by measuring a current of the display panel generated in response to the second reference voltage when the first measurement current is greater than the reference current, comparing the second measurement current with the reference current, and obtaining a panel setting voltage based on the first reference voltage and the second reference voltage when the second measurement current is less than or equal to the reference current.
