Patent attributes
A test method of a display panel and a test device are disclosed. The test method includes outputting a data signal of a preset test image to the display panel to cause plural light emitting elements to emit light according to the preset test image; outputting a starting signal to a scan circuit in the display panel to cause the scan circuit to output an active level of a switching circuit to the plural rows of first scan lines as connected, successively, according to a preset timing sequence; receiving a sensing signal from a sensor circuit, including voltage value information of a first terminal of every light emitting element; comparing the voltage value information of the first terminal of every light emitting element with the preset test image to obtain a test result. The test method solves the problem of missing detection of Mura.
