Abstract

A light-emitting drive circuit, which includes cascaded N light-emitting drive sub-circuits, and an n-th light-emitting drive sub-circuit, includes: a first pull-up control sub-circuit configured to pull up a potential of a first node to a first potential in a trigger phase; a first pull-down control sub-circuit configured to pull down the potential of the first node to a second potential in an output phase and pull up the potential of the first node to a third potential in a reset phase; a pull-up sub-circuit configured to pull up an n-th stage light-emitting drive signal to a high potential; a second pull-down control sub-circuit configured to pull up a potential of a second node to a fourth potential in the output phase; and a pull-down sub-circuit configured to pull down the n-th stage light-emitting drive signal to a low potential.
