Abstract: A coating method for liquid crystal alignment film of TFT-LCD, at least two different sized nozzles are used to perform N nested hollow rectangular coatings, the N nested hollow rectangles are ordered based on 1, 2 to N measurements sequentially from the smallest to the biggest, and a smaller sized nozzle is employed for the Nth nested hollow rectangular coating on an edge.

Abstract: A coating method for liquid crystal alignment film of TFT-LCD including: forming a layer of hydrophobic film on a TFT/CF substrate corresponding to a non-display area, the hydrophobic film separates the TFT/CF substrate into a plurality of rectangular opened areas which are separated from each other, each of the rectangular opened areas corresponds to a display area and its outer frame is formed by the hydrophobic film; and coating of a liquid of a material of an alignment film along a boundary of the rectangular opened area. Accordingly, edge waves caused by spreading of drips of the material of the alignment film can be reduced, so that a precision of printing of the alignment film can be controlled effectively.
