Drive circuit for a LCD device |
摘要 |
A drive circuit for a LCD device has a plurality of drive sections corresponding to a plurality of data lines in a pixel matrix. Each drive section receives a corresponding portion of a video signal to deliver the signal portion to a corresponding data line. The output circuit of each drive section includes an nMOS transistor, first switch, second switch and a pMOS transistor connected in series between power source lines to output the signal portion through the output node connecting the first switch and the second switch together. The nMOS transistor and pMOS transistor operate alternately for delivering a a positive signal and negative signal, respectively, thereby making it unnecessary to reset the data line for reducing power dissipation.
