Abstract: According to embodiments of the present disclosure, there may be provided a controller, a display device and a driving method. In consideration of that a hysteresis by an image data voltage supplied to a subpixel during an active time may exert an influence on a real-time sensing process, by correcting a reference sensing driving data voltage on the basis of an offset voltage, it is possible to correct the influence of a hysteresis exerted on sensing of the characteristic value of a driving transistor.
