Patent ID: 11192356

Abstract:
The ink jet printing system may have a printing section and a testing section. The ink jet printing system may include a first alignment mark disposed in the printing section along a first direction, a second alignment mark disposed in the testing section along a second direction perpendicular to the first direction, an ink jet head for providing chemical liquid onto a substrate, a first identification member proximate to the ink jet head, the first identification member identifying the first alignment mark and the second alignment mark, a gantry for moving the ink jet head between the printing section and the testing section, a second identification member proximate to the gantry, the second identification member identifying discharging points of the chemical liquid in the testing section, and a control member for correcting discharging points of the chemical liquid discharged from the ink jet head onto the substrate in the printing section based on a result that the second identification member identifies the discharging points of the chemical liquid in the testing section. The testing section may be arranged in substantially parallel with the printing section along the first direction.
