Title:
METHOD FOR POWERING LCD DEVICE AND AUXILIARY CAPACITY LINE
Document Type and Number:
WIPO Patent Application WO/2013/018596
Kind Code:
A1
Abstract:
Provided is a CS-drive lcd device that reduces power consumption. A CS driver (500) is configured from a CS shift register (510) and a CS output unit (520). The CS shift register (510) outputs control signals (COUT(1)-COUT(m)) on the basis of a CS clock signal (CCK). The CS output unit (520) respectively outputs auxiliary capacity signals (CSS(1)-CSS(m)) on the basis of the control signals (COUT(1)-COUT(m)). A scanning period (T1) is followed by an idle period (T2). During the idle period (T2), the CS driver (500) operates on the basis of the CS clock signal (CCK) of the idle period CS frequency (fcck2). The idle period CS frequency (fcck2) is lower than the scanning period CS frequency (fcck1).
