Abstract

The invention provides a grid electrode driving circuit. The grid electrode driving circuit comprises cascaded shifting registers in multiple stages, wherein each shifting register comprises an input module, a first reset module, a second reset module, an energy storage module, an output module and a pull-down node potential generating module, and at least two shifting registers share one pull-down node potential generating module. The invention also provides a display panel comprising the grid electrode driving circuit and a method used for driving the grid electrode driving circuit.

Description

technical field [0001] The present invention generally relates to the field of display technology, and more particularly relates to a gate driving circuit, a driving method for the gate driving circuit, and a display panel including the gate driving circuit. Background technique [0002] With the development of display technology, the application of liquid crystal display devices is also becoming more and more extensive. A liquid crystal display generally includes a color filter substrate and an array substrate oppositely arranged, and a liquid crystal is arranged between the color filter substrate and the array substrate. Wherein, a source driving circuit and a gate driving circuit (GOA) are arranged on the array substrate, and both the source driving circuit and the gate driving circuit are located at the edge of the array substrate. Since the gate driving circuit is usually arranged at the edge of the array substrate, how to reduce the space occupied by the gate driving ...
