N2 - Color filter (CF), one of the key components for liquid crystal display (LCD), is costly to make from repeated lithography processes. The defects may be created during the repeated lithography processes. The recycling defect CF panels are environmental unfriendly and not cost-effective process. CF repairing is an important cost-effective technical process to improve product yield. In this study, a solvent-less repaired ink system was studied. The optimized formulas of red, green, blue, and black inks have passed the quality control, reliability, and life-time tests. The new solvent-free ink system possesses the balance characteristics in liquid fluidic, UV reactivity, and color saturation. The energy has been conserved without high temperature process for removing organic solvent. The new system exhibits the state-ofthe- art fabrication process without unnecessary energy waste. As a result, the solvent-less CF repair inks offer a promising result for contributing to a low carbon process in the near future.
