Abstract
A detecting apparatus and method, repairing apparatus and method, and repairing system of AMOLED display device are provided. The detecting apparatus includes: an illuminating device for sequentially illuminating a plurality of detection regions of a screen of the AMOLED display device, the screen being divided into the plurality of detection regions, each of the detection regions including at least one light-emitting unit; a current detecting device for acquiring a detection current which is a sum of driving currents of the light-emitting unit in the detection region being illuminated; and a judging device for judging whether the detection region corresponding to the detection current is a defective region according to the detection current. The apparatus can detect luminance uniformity of the AMOLED display device. The detection efficiency is high, the detection standard is unified and the detection accuracy is high.
