Abstract
The invention provides an apparatus and a method for rubbing the alignment layer in the LCD substrate. The rubbing apparatus of the present invention further includes a conditioning roller, in addition to the rubbing roller, to rejuvenate the rubbing roller in real time so as to lengthen the roller lifetime in the rubbing process and increase the rubbing rate. By employing the conditioning roller along with the rubbing roller, the rubbing process includes an extra conditioning step for conditioning the rubbing roller, thus shortening the production cycle time and increasing the throughput.
