Abstract

The invention provides a driving circuit of a display panel and a display device. The driving circuit comprises a GOA circuit, the GOA circuit transmits a scanning driving signal to the display panel through a corresponding gate signal line, the driving circuit further comprises a pull-down module and a control bus, one end of the pull-down module is electrically connected with one end of the gate signal line correspondingly, and the other end of the pull-down module is electrically connected with the control bus, the pull-down module is started in a delayed mode when the gate drive signal descends so as to increase the potential descending speed of the pull-down module, then the charging time of the thin film transistor is prolonged, and the narrow-frame display panel is achieved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a driving circuit and a display device of a display panel. Background technique [0002] In recent years, with the continuous development of display technology, people have put forward higher requirements on the types, uses and functions of display panels. [0003] Among them, the narrow bezel display panel has gradually become a hot spot in the market, and the narrow bezel display panel has attracted people's attention because of its narrow bezel, high screen-to-body ratio, and large displayable area. Taking a thin film transistor (thin film transistor, TFT) liquid crystal display device as an example, it includes a liquid crystal display panel, a gate drive circuit (gate drive circuit) and a source drive circuit (source drive circuit). In the prior art, in order to achieve a narrow frame, the drive circuit (gate on source, GOA) outside the display area of ​​th...
