The graph of FIG. 10 is divided into a plurality of periods. The plurality of periods may include a pre-compensation activation period H1, an Off-RS compensation period H2, a cooling time period H3, an afterimage compensation period H4, and a post-compensation activation period H5.

The pre-compensation activation period H1 and the post-compensation activation period H5 may be periods in which AC power is supplied to the display panel 150 and thus the image is driven on the display panel 150.

The Off-RS compensation period H2 may be a period in which the compensation for the voltage of the display panel 150 is performed without regard to the temperature of the display panel 150 (that is, the cooling time is not needed).

The Off-RS compensation period H2 may be a period of a standby state in which AC power is supplied, but DC power is not supplied.

The cooling time period H3 may be a period that turns off the screen of the display panel 150 before the afterimage compensation.

The afterimage compensation period H4 is a period that compensates for the deterioration of pixels constituting the display panel 150 after the cooling time period H3.

If the afterimage compensation is performed in a state in which the cooling time of the display panel 150 is not satisfied, a pixel deterioration compensation rate may be reduced.

This will be described with reference to the accompanying drawings.
