Correction system and method for alignment film printing plate

Abstract

Disclosed is a correction system for an alignment film printing plate, including: a roller and a printing plate mounted as a sleeve outside of the roller, wherein a first end portion of the printing plate is provided thereon with a plurality of columns of buckle groups, and a second end portion of the printing plate is provided thereon with a plurality of columns of slot groups engaged with the buckle groups. The correction system for the alignment film printing plate further includes an image controller used for measuring a deviation value between an actual position and a preset position for printing of an alignment film on a substrate. The correcting system of the alignment film printing plate has a simple structure and is capable of realizing different stretching degrees of an alignment film pattern at different positions on the printing plate, so as to improve a correction effect of the printing plate. As a result, deviation can be reduced between an actual position and a preset position for printing of the alignment film on the substrate, without significant increase in costs.
