That is, before the afterimage compensation, the display panel 150 needs to secure the cooling time during which the operation must be turned off.

If the supply of AC power to the OLED display apparatus 100 is maintained and the supply of DC power is interrupted, the processor 190 is in an enabled state, and thus, it is possible to measure the cooling time during which the display panel 150 is turned off.

In one embodiment, the processor 190 may use a timer to measure the time during which the display panel 150 has been turned off and determine whether the measured time satisfies the cooling time.

In another embodiment, if the supply of AC power is maintained and the supply of DC power is interrupted, the processor 190 may measure the cooling time of the display panel 150 by using the discharge circuit 130, which will be described below.

Meanwhile, even if the supply of AC power is interrupted, the processor 190 may check the cooling time of the display panel 150 by using the discharge circuit 130.

The processor 190 may measure the cooling time of the display panel 150 by checking the discharge amount of the capacitor which is measured by the discharge circuit 130.

The specific operation of the processor 190 will be described below in more detail.

FIG. 2 is a block diagram for describing the configuration of the discharge circuit according to an embodiment of the present disclosure, and FIG. 3 is a circuit diagram for describing the actual circuit configuration of the discharge circuit according to an embodiment of the present disclosure.
