Title:
DISPLAY DEVICE AND DRIVE METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/042622
Kind Code:
A1
Abstract:
Provided are a display device capable of rapidly writing an image signal onto a pixel-forming unit, and a drive method therefor. A batch drive signal (VBD) for simultaneously bring a plurality of scanning signal lines into a selection state is simultaneously applied to the plurality of scanning signal lines in a blanking period, whereby a selection is made and a plurality of pixel-forming units are simultaneously pre-charged. Next, a plurality of scanning signal lines are selected in order, a plurality of image signals representing an image which should be displayed are generated as signals where the voltage polarity on each individual data signal line is inverted, and each are applied to the plurality of data signal lines. At this time, given that charging is started from a state in which a voltage close to the image signal voltage has been previously charged in each pixel-forming unit, it is possible to write the image signal rapidly onto the pixel forming unit.
