| description | The present invention provides an apparatus and a method for repairing defects of a micro LED display, the apparatus for repairing a micro LED display of the present invention comprising: a stage for accommodating a micro LED display, the micro LED display comprising a micro LED chip and a circuit pattern for driving the micro LED chip; the laser source is used for providing laser to remove a defect part of the micro LED display; and an optical module which changes the path of the laser light generated from the laser light source and irradiates the laser light to remove a preset specific area so as to repair the defective part of the micro LED display, the optical module removes the predetermined specific area to a depth at which a lower circuit pattern of the micro LED display, which provides power required for operation to the micro LED chip, is exposed. According to the structure, the effect of repairing the defects, which cannot be repaired through a traditional repairing method, in the micro LED display |
