An inkjet printing process for color filter fabrication is one of key technologies for next generation processes. To prevent ink overflow from the black matrices (BM) bank, two effective surface pre-treatments were introduced in this study. The contact angle of chemical treatment and CFx plasma treatment can be increased from 12 to 52 degrees and 12 to 27 for red ink, respectively.

A novel ink jet printing process without additional photolithography process for large area color filter fabrication has been developed in this study. A 100x100 mm(2) model of 32" color filters was fabricated for evaluation. New developed RGB inks were able to achieve 73% NTSC standard with the thickness of R, G, and B films at 1.80, 1.90, and 1.80 pm, respectively. The overflow issue can be solved by surface pretreatments, and color inks formulation.

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%.
