Inkjet printing system

Abstract

An ink jet printing system may have a printing section and a maintenance section. The ink jet printing system may include at least one first alignment mark disposed in the printing section along a first direction, an ink jet head for discharging chemical liquid onto a substrate, at least one second alignment mark disposed in the maintenance section along a second direction perpendicular to the first direction, at least one first identification member disposed proximate to the ink jet head, the at least one first identification member identifying the at least one first alignment mark and the atleast one second alignment mark, a gantry extended from the printing section to the maintenance section, the gantry moving the ink jet head between the printing section and the maintenance section, at least one second identification member disposed proximate to the gantry, the at least one second identification member identifying discharging points of the chemical liquid in the maintenance 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 at least one second identification member identifies the discharging points in the maintenance section.

Description

[0001] This application enjoys the priority of Korean Patent Application No. 10-2019-0068423 filed with the Korean Intellectual Property Office on June 11, 2019. technical field [0002] Exemplary embodiments of the present invention relate to inkjet printing systems. More particularly, exemplary embodiments of the present invention relate to an inkjet printing system capable of accurately discharging a chemical liquid onto a pixel area of ​​a substrate. Background technique [0003] Recent display devices such as liquid crystal display devices or organic light emitting display devices require high resolution. In order to obtain such a display device with high resolution, the substrate used to manufacture the display device should have more pixel areas per unit area. On the other hand, it may be difficult to obtain a display device with high resolution if the liquid medicine is not accurately spit out onto the dense pixel area of ​​the substrate. Contents of the invention...
