Claim:
1. A patterning apparatus, comprising: a plurality of liquid jet units arranged in one or more columns and configured to jet an anti-etching liquid onto a surface of a substrate, wherein each liquid jet unit comprises a jet nozzle and an anti-etching liquid cell connecting with the jet nozzle, and in each column the liquid jet units are arranged such that: the jet nozzles are aligned along a central line of the column while adjacent two anti-etching liquid cells are located on opposite sides of the central line of the column each jet nozzle corresponds to a single anti-etching liquid cell, and the anti-etching liquid cells are disposed on alternating sides of the consecutive jet nozzles along the central line; a plurality of exposure units configured to expose light on the anti-etching liquid jetted on the surface of the substrate to heat and cure the jetted anti-etching liquid to form anti-etching patterns on the surface of the substrate; and a control module configured to control motion status and jetting status of the plurality of liquid jet units and to control motion status and exposure status of the plurality of exposure units, so as to form the anti-etching patterns at a predetermined line width and thickness.
