Abstract

The invention discloses a substrate and a method for determining the position of the alignment film boundary of the substrate. The substrate is used for determining the position of the alignment film boundary during the first time of substrate manufacturing. Multiple positioning units are arranged on the edge of the display area of the substrate. Each positioning unit comprises a plurality of positioning marks arranged in the direction perpendicular to the contour line of the substrate. The substrate and the method solve the problem that the position of the alignment film boundary of a newly-manufactured product produced for the first time needs to be manually measured, the open-line debugging time can be remarkably shortened, labor can be saved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of production and manufacture of liquid crystal displays, in particular to a substrate and a method for determining the position of the boundary of an alignment film of the substrate. Background technique [0002] Polyimide alignment film (ie, PI alignment film) is a polymer film structure that enables liquid crystal molecules to be aligned according to a fixed pretilt angle. Alignment films are arranged on the upper and lower substrates of the liquid crystal display, and are generally located between the transparent electrodes and the liquid crystal molecules. The alignment film can be formed by coating with a jet printing process (Inkjet). However, since the Inkjet process is non-contact, and the material used in jet printing is in the shape of droplets and has fluidity, in order to ensure that the generated alignment film meets the design requirements, it is necessary to form an alignment film during the process o...
