Abstract
A display panel with GOA circuit invalid detection is provided. A plurality of cascading gate-driver-on-array (GOA) circuit units are disposed in the display panel. The GOA circuit units are divided into a plurality of groups of GOA circuit units. The last stage of the GOA circuit units in each group of GOA circuit units is connected to a test line. One group of GOA circuit units is treated as a unit to detect whether any GOA circuit unit in each group is invalid. This improves accuracy in GOA circuit invalid detection.
