A method of compensating for changes in characteristics of a panel of a display device is disclosed. The panel includes subpixels, each of the subpixels including an organic light emitting diode. The method comprises: counting, by the display device, at least one on-time of at least one subpixel of the subpixels, the at least one on-time indicating a number of occurrences of light emitted by the at least one subpixel; transmitting, by the display device, the at least one on-time to a remote compensation server through a network; determining, by the remote compensation server, an organic light emitting diode compensation factor based on the at least one on-time; transmitting, by the remote compensation server, the organic light emitting diode compensation factor to the display device through the network; and driving, by the display device, the panel based on the organic light emitting diode compensation factor.
