14. A driving method for a display device, the driving method comprising:
a capacitor voltage charging step of charging a storage capacitor included in a subpixel with a predetermined voltage;
a charging ratio sensing unit initializing step of initializing a charging ratio sensing unit electrically connected to the subpixel;
a charged voltage tracking step of tracking the predetermined voltage charged in the storage capacitor using the charging ratio sensing unit; and
a charged voltage sampling step of sampling the predetermined voltage tracked by the charging ratio sensing unit,
wherein the capacitor voltage charging step, the charging ratio sensing unit initializing step, the charged voltage tracking step, and the charged voltage sampling step are included in a subpixel charging ratio sensing step, and
wherein the subpixel charging ratio sensing step includes a first subpixel charging ratio sensing step for a first subpixel that is the subpixel and a second subpixel charging ratio sensing step for a second subpixel.
