Several applications for inkjet technology are being developed based on the concept of a micro-liquid process. First, activematrix thin-film diode liquid-crystal displays (TFD-LCDs) equipped with color filters are manufactured by using pigmented inkjet printing. Fundamental technologies have been optimized, including pigment-dispersed solvent inks, bank materials deposited on a metallic black matrix, a piezoelectric drop-on-demand inkjet head, an original inkjet machine, a drying process for color layers, and the fabrication of LCD panels. Applications in organic light emitting diodes (OLEDs), organic thin film transistors (TFTs), micro-lenses, metal wiring processes and other areas are planned, and visionary industrial inkjet applications for the future are presented.
