Rib-free ink-jet printing device fabrication on hetrogeneous surfaces opens a new possibility for greener processes. The integrity of ink droplets was maintained with less than 3 degrees contact angle differences on the heterogeneous surfaces after surface treatment. The breaking of color lines and color mixing were avoided by accelerating solvent evaporation. The inks were greatly conserved without the need for additional lithography process for rib structure.

A 4 "color filter panel was successfully prepared by rib-less ink jet printing process. The smeared ink issue can be controlled by surface treatment on both Cr and glass with similar contact angle. The color line formation can be prepared by either two-step printing process at room temperature or one-step printing at elevated temperature. The thickness of red, green and blue films were about 1.2 mu m, 1.0 mu m and 1.0 mu m, respectively. The panel's NTSC value was estimated at 53.5 +/- 0.7%.
