Ink-jet printing method and apparatus for manufacturing color filters

摘要

An ink-jet printing method and apparatus for manufacturing color filters of the invention comprises an printing head module, a table, an air jet module, an optical system, and a controlling system. The table is used to support the filter substrate and move relative to the printing head module. The optical system is used for real-time calibration so the printing head module is able to precisely spray ink droplets to the substrate. An air jet head module is then used to accurately distribute ink droplets. The conventional absorb layer is not necessary. The precision of spraying and distribution of ink droplets are thus much improved over the conventional technique.
