Abstract

This study discloses a novel application of Ink-Jet printing technology on manufacturing color filter for LCD. With the special inks invested by ITRI (Industrial Technology Research Institute, Taiwan), by using this system with OES self developed head, a strip-type color filter (pixel size 113 μm * 339 μm, with 20 μm black matrix width) made by ink-jet printing method is achieved. The results show that the accuracy of motion and printing are satisfactory. However, the innate characteristics of satellite drop problem by ink-jet method reduce the yield rate. In this study, a driving waveform control method is provided to modulate the ink discharging condition; the preheating and inter-cooling function are elaborate to improve the printing quality. Experimental observation shows a significant reduction in satellite drop and its position deviation, and the dots circularity is acceptable.
