Claim 5:
6. A driving method of a display device including pixels connected to a scan line, a control line, a data line, and a sensing line, the display device being driven to include a display period for displaying an image and a sensing period for sensing characteristics of a driving transistor included in each of the pixels, comprising: supplying a sensing data signal to the data line and an initialization voltage to the sensing line during the sensing period, wherein, in supplying the initialization voltage, preset first and second reference initialization voltages among the initialization voltage are supplied to the pixels; obtaining a sensing current value from at least one of the pixels through the sensing line, wherein, in the obtaining the sensing current value, first and second reference sensing current values respectively corresponding to the preset first and second reference initialization voltages are obtained; storing the first reference sensing current value and the second reference sensing current value; performing deep learning using an artificial neural network model so that a reference image data corresponding to the first reference sensing current value and the second reference sensing current value is output from each of the pixels; and generating compensation image data according to a sensing pixel current value among the sensing current value using the artificial neural network model learned to output the reference image data.
