Abstract
Official abstract text for this publication.
Provided is a shift register unit, a gate driving apparatus and a display device capable of increasing a lifespan of a shift register. The shift register unit according to the present disclosure includes: a first thin film field effect transistor, a drain thereof connected with a first signal terminal, a source thereof connected with the outputting node at the present stage, a gate thereof connected with a first node; a second thin film field effect transistor, a drain thereof connected with the first signal terminal, a source thereof connected with the pulling-up node, and a gate thereof connected with the first node; a third thin film field effect transistor, a drain thereof connected with a second signal terminal, a source thereof connected with the outputting node at the present stage, and a gate thereof connected with a second node; a fourth thin film field effect transistor, a drain thereof connected with the second signal terminal, a source thereof connected with the pulling-up node, and a gate thereof connected with the second node; and a node voltage control module, configured to control the first node and the second node to be in a high potential state alternatively when the shift register unit is in a pulling-down phase. The present disclosure increases the lifespan of the shift register.
First claim
Opening claim text (preview).
What is claimed is: 1. A shift register unit comprising a capacitor, wherein one terminal of the capacitor is connected with an outputting node at a present stage, and the other terminal of the capacitor is connected with a pulling-up node, and the shift register unit further comprises: a first thin film field effect transistor, a drain thereof connected with a first signal terminal, a source thereof connected with the outputting node at the present stage, a gate thereof connected…
