ACTIVE LINE REPAIR FOR THIN-FILM-TRANSISTOR LIQUID-CRYSTAL DISPLAYS

A new method for repairing line defects during panel fabrication is de scribed for high-resolution thin-film-transistor liquid crystal displa ys (TFT/LCDs), This approach uses electronic means in conjunction with physical rewiring to supply the appropriate data signal to the undriv en segment of an open data line. Active line repair is simple and inex pensive, with the capacity for repairing numerous line defects, We hav e successfully implemented this repair approach on 10,4-in.-diagonal, 157-dpi prototype TFT/LCDs, This method is particularly suited for low er-volume, large-area, high-resolution TFT/LCDs, which are difficult t o produce with high yield.
