Claim 9:
10. A display device, comprising:
a display panel, comprising:
a plurality of data lines;
a plurality of gate lines; and
a plurality of pixel circuits under test, coupled to the plurality of data lines and the plurality of gate lines respectively; and
a detecting signal source, coupled to each of the plurality of pixel circuits under test and the plurality of data lines of the display panel, and configured to generate a first detecting signal to each of the plurality of pixel circuits under test so that each of the plurality of pixel circuits under test generates a detection result signal to the plurality of data lines according to the first detecting signal and a second detecting signal, wherein the detecting signal source is configured to determine whether each of the plurality of pixel circuits under test is abnormal according to the detection result signal, wherein if each of the plurality of pixel circuits under test is abnormal, the detecting signal source is configured to lock the at least one of the plurality of pixel circuits under test which is abnormal according to a plurality of positioning points of the plurality of data lines and the plurality of gate lines.
