Driving circuit, gate driving circuit and display panel

Abstract

The invention discloses a driving circuit, a gate driving circuit and a display panel. The driving circuit comprises a first gate point, a pull-up circuit, an isolating switch circuit, a second gate point, a first output circuit, a second output circuit and a pull-down circuit, the pull-up circuit pulls up the first gate point when receiving an input signal; the isolation switch circuit electrically isolates the second gate point from the first gate point when the first gate point is at a low potential, and electrically connects the second gate point with the first gate point when the first gate point is at a high potential; the first output circuit outputs a first driving signal according to a first clock signal when the first gate point is at a high potential; the second output circuit outputs a second driving signal according to a second clock signal when the second gate point is at a high potential; when the pull-down circuit receives a pull-down control signal, the first grid electrode point, the output end of the first output circuit and the output end of the second output circuit are pulled down to low potential; when the first gate point is at a high potential, the pull-down is stopped. And the output signal is more stable.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving circuit, a gate driving circuit and a display panel. Background technique [0002] With the improvement of living standards, people also put forward higher requirements for liquid crystal display products, such as lower prices and narrower borders. [0003] In the manufacturing process of liquid crystal displays, GDL (Gate Driver less, less gate drive) circuit drive technology is usually used, which is to abandon the traditional gate drive chip and replace it with the gate drive circuit structure. On the glass substrate of the panel, there is no need to use chip drivers on both sides of the display panel, which greatly reduces the product cost. [0004] In order to achieve a smooth driving effect, the common GDL circuit usually precharges the common working node of the output circuit to achieve a higher voltage level, so that it can be coupled with the clock s...
