Title:
SCANNING-LINE DRIVE CIRCUIT AND DISPLAY DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2022/070404
Kind Code:
A1
Abstract:
This scanning-line drive circuit is configured such that a plurality of unit circuits are connected in multiple stages. Each of the unit circuits includes: a first transistor having a first conduction terminal to which a voltage of a first level is applied and a second conduction terminal connected to a first node; a second transistor having a second conduction terminal to which a voltage of a second level is applied; a third transistor having a first conduction terminal connected to the first node and a second conduction terminal connected to the first conduction terminal of the second transistor; a fourth transistor having a first conduction terminal connected to a control terminal of the third transistor, and a control terminal and a second conduction terminal to which the voltage of the second level is applied; and an output transistor having a control terminal connected to the first mode and a second conduction terminal connected to an output terminal.
