Abstract

Provided is a gate drive circuit, wherein the gate drive circuit is connected to a row pixel unit and the row pixel unit comprises a row pixel drive module and a light-emitting element that are mutually connected. The row pixel drive module comprises a drive transistor (T1), a drive module and a compensation module. The compensation module connects in a gate scanning signal and the drive module connects in a drive level. The gate drive circuit also comprises a row pixel control unit, which is used for providing the gate scanning signal for the compensation module and providing the drive level for the drive module so as to control the compensation module to compensate a threshold voltage of the drive transistor (T1) and control the drive module to drive the light-emitting element. Also provided are a gate drive method, a gate on array circuit and a display apparatus.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate drive circuit, a method, an array substrate row drive circuit and a display device. Background technique [0002] In the prior art, there is no GOA (Gateonarray, array substrate row drive, directly fabricating the gate drive circuit on the array substrate) that can provide Vth (threshold voltage) compensation for OLED (Organic Light-Emitting Diode) display panel pixels. circuit, but only provides a pixel design or a single-pulse GOA circuit with pure Vth compensation function. [0003] Since the OLED pixel design mostly adopts the current control type, the Vth inhomogeneity in the entire OLED display panel and the VthShift (drift) generated after long-term operation will reduce the display uniformity of the OLED display panel. In order to improve the process integration of OLED display panels while reducing costs, the use of integrated gate drive technology is a ...
