Abstract
A method and device for detecting a defect of a display panel, the method comprises steps of: connecting at least one electrical test pad on the display panel to a first detecting terminal, and connecting another at least one electrical test pad on the display panel to a second detecting terminal; providing a preset voltage between the first detecting terminal and the second detecting terminal; and, detecting whether magnitudes of currents passing through the first detecting terminal and the second detecting terminal within a predetermined time are less than a preset current threshold, and if not, then determining there is a defect on the display panel. The present disclosure can implement effective detection and interception of a progressive defect or badness in the display panel.
