Abstract:
Disclosed is a display device. The display device comprises: a thin film transistor formed at the intersection of a gate line and a data line; a common electrode line for providing a common voltage to a liquid crystal capacitor and a holding capacitor; and a controller for supplying a data voltage corresponding to a data signal to the liquid crystal capacitor and the holding capacitor through the thin film transistor during an active period, wherein the controller identifies whether a blank period begins and a next data signal is received after a threshold time, and controls the common electrode line to adjust the common voltage on the basis of the identification result.
