LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING SAME

Title:

LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING SAME

Document Type and Number:

WIPO Patent Application WO/2014/054331

Kind Code:

A1

Abstract:

Provided are: a liquid crystal display device configured so that degradation of display quality when pausing driving is performed by alternate current driving can be suppressed; and a method for driving the liquid crystal display device. As the gray scale level value of a previous frame and the gray scale level value of a current frame are different, an overshoot voltage having an absolute value greater than that of a signal voltage is applied to data signal lines. Next, in a second driving frame, normal driving is performed, whereby a signal voltage having the same polarity as that of the overshoot voltage is written in the data signal lines. Further, in a first driving frame of a third pausing driving period, as the gray scale level value of a previous frame and the gray scale level value of a current frame are equal to each other and the value thereof is equal to or greater than a boundary value, undershoot driving is performed. An undershoot voltage having an absolute value smaller than the signal voltage is applied to the data signal lines. Next, in a second driving frame, normal driving is performed, whereby a signal voltage having the same polarity as that of the undershoot voltage is written in the data signal lines.
