Title:
DRIVING CIRCUIT, DRIVING METHOD, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/051204
Kind Code:
A1
Abstract:
A driving circuit, a driving method, and a display panel. The driving method comprises: after a first thin-film transistor (T1) is turned on and the voltage at a first node (A) is controlled to be an initialization voltage (Vref), controlling the voltage at a second node (B) to be a threshold voltage on the basis of the initialization voltage (Vref) and respective voltage differences of a second thin-film transistor (T2) and a fourth thin-film transistor (T4), which are turned on; turning on a third thin-film transistor (T3) and compensating for the threshold voltage to obtain a driving voltage; turning on a fifth thin-film transistor (T5) by means of the driving voltage to input a driving current; and controlling the driving current to flow through a sixth thin-film transistor (T6), which is turned on, so as to drive a light-emitting diode (D1).
