The TEG test key of the array substrate includes a glass substrate, a multi-buffer layer, an active layer, a gate insulating layer, a gate electrode layer, an interlayer insulating layer, a source and drain electrode layer, and an organic planarization layer stacked in sequence. The TEG test key of the array substrate is defined with two test zones and a connecting zone, and each test zone is provided with a groove exposing the gate electrode layer. The gate electrode layer in the test zones is electrically connected to the source and drain electrode layer in the connecting zone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"TEG test key of array substrate and display panel","description":"A test element group (TEG) test key of an array substrate and a display panel thereof are provided.
