Abstract

The invention provides a grid driving circuit, a grid driving method, an array substrate row driving circuit and a display device. The grid driving circuit is connected with a row pixel unit, the row pixel unit comprises a row pixel driving module and a light emitting component which are mutually connected, wherein the row pixel driving module comprises a driving transistor, a driving module and a compensation module, the compensation module is connected with the first row scanning signal, the driving module is connected with the second row scanning signal and a driving level, the grid driving circuit further comprises a row pixel control unit used for providing the first row scanning signal for the compensation module and used for providing the second row scanning signal and the driving level for the driving module, so the compensation module is controlled to compensate threshold voltage of the driving transistor, and the driving module is controlled to drive the light emitting component. The grid driving circuit can compensate the pixel threshold voltage and a driving pixel and improves an integration level.

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...
