The present invention provides an array substrate and a detecting method therefor, a display panel and a display device. The array substrate comprises a plurality of data lines, a plurality of short circuit rings respectively provided at ends of the plurality of data lines, and a common wire connecting the plurality of short circuit rings in series, wherein, a switch unit is provided between the end of each data line and the corresponding short circuit ring, and the switch unit is configured to disconnect the data line with the corresponding short circuit ring in a testing stage. The present invention can improve the detection rate and accuracy rate in an array test.

Array substrate and detecting method therefore, display panel, and display device for improved detection rate and accuracy of an array test

An array substrate comprising an electrical connection block exposed to its surface. By manufacturing a passivation layer via hole in a passivation layer, a drain electrode or a pixel electrode of a thin-film transistor is exposed, so that the electrical connection block fills the passivation layer via hole and is provided in contact with the drain electrode or the pixel electrode. Thereby, when the electrical characteristic value of a TFT is measured, the pixel probe of a measuring apparatus may be electrically connected with the drain electrode or the pixel electrode by directly contacting the electrical connection block, so that the measuring of the electrical characteristics of the TFT may be realized.
