Abstract
A display device may include: a thin film transistor operatively associated with 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.

A display device comprising:
- a thin film transistor operatively associated with 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 configured to supply a data voltage corresponding to a data signal to the liquid crystal capacitor and the holding capacitor via at least the thin film transistor during an active period,
- wherein the controller is configured to identify whether a next data signal is received past a threshold time after a blank period begins, and
- the controller is configured to control the common electrode line to adjust the common voltage based on whether the next data signal is received past the threshold time after the blank period begins.
