Abstract

The invention provides a grid driving circuit and method, an array substrate row driving circuit and a display device. The grid driving circuit is connected with a row pixel unit, and the row pixel unit comprises a row pixel driving module and a light emitting element which are connected with each other. The row pixel driving module comprises a driving transistor, a driving module and a compensation module. A grid scanning signal is connected into the compensation module. A driving control signal and a driving level are connected into the driving module. The grid driving circuit comprises a row pixel control unit and a driving control unit, wherein the row pixel control unit is used for providing the grid scanning signal for the compensation module and providing the driving level for the driving module so as to control the compensation module to compensate for the threshold voltage of the driving transistor , and the driving control unit is used for providing a driving control signal for the driving module so as to control the driving module to drive the light emitting element. The pixel threshold voltage and the driving pixels can be compensated for at the same time, and thus the integration is improved.

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] There is no GOA (Gate on array, array substrate row drive) that can provide Vth (threshold voltage) compensation for OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel pixels. Array substrate) circuits, but only provide a pixel design with Vth compensation function or a single-pulse GOA circuit. [0003] Since the OLED pixel design mostly adopts the current control type, the Vth inhomogeneity in the entire OLED display panel and the Vth Shift (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 future development trend. However, the V...
