Abstract

The present invention relates to an apparatus and method for repairing a display using conductive ink. The apparatus for repairing a display using conductive ink according to the present invention comprises: a pressure control unit for supplying the conductive ink by applying pressure to an ink storage unit in which the conductive link is stored; a nozzle for discharging the conductive ink; a stage on which a substrate to be coated with the discharged conductive ink is placed; and a voltage control unit for coating the conductive ink on the substrate in a line type by applying a direct current (DC) voltage to the nozzle, and coating, on the conductive ink coated in the line type, the conductive ink in a drop type by applying a pulse voltage to the nozzle.

Description

technical field [0001] Embodiments of the present invention relate to a display repair apparatus and method using conductive ink. [0002] This invention, as a development project of the Ministry of Industry of Korea (project number: 10048560), originates from the Advanced Technology Research Center (ATC) project implemented by COWINDST Co., Ltd. (2014.06.01-2019.04.30) [project name: for rollable OLED 1μm line width level EHD Direct repair technology development]) results. Background technique [0003] Generally, etching methods, screen printing methods, vacuum evaporation methods, etc. are mainly used as methods for forming conductive wiring in the field of electric and electronic parts. Recently, in the fields of displays such as FED, PDP, and LCD, various metal pastes are used to form internal electrodes. The metal used for the metal paste used in the conductive coating used in the existing electrode materials can use Au, Ag, Cu, Pt, Re, Al, Fe, Ni, etc., but due to th...
