Abstract

The invention provides a shifting register and a grid driving circuit and a driving method thereof and a liquid crystal display device. The shifting register comprises a pull-up sub-circuit, a first output sub-circuit, a reset sub-circuit and a second output sub-circuit, wherein when a first input end receives first input signals, the pull-up sub-circuit sets the potential of a pull-up node as a wording potential; when the potential of the pull-up node is the working potential, the first output sub-circuit outputs grid driving signals at an output end according to first clock signals which are received by a first clock signal end; when reset signals are received by a reset end, the reset sub-circuit sets the potential of the pull-up node and the output end as reset potential; when second input signals are received by a second input end, the second output sub-circuit outputs the grid driving signals at the output end in the time bucket apart from the period of displaying a one frame picture.

Description

technical field [0001] The present disclosure relates to a shift register, a gate driving circuit and a driving method thereof, and a liquid crystal display. Background technique [0002] Liquid crystal displays display images by continuously deflecting liquid crystals. Liquid crystals generally have capacitance parameters, and the equivalent capacitance of liquid crystals is also called liquid crystal capacitance. In addition, a storage capacitor is usually provided between the pixel electrode and the common electrode to help maintain the voltage that deflects the liquid crystal. The liquid crystal is deflected according to the charge stored in the liquid crystal capacitor and the storage capacitor. [0003] In the process of displaying different pictures, the liquid crystal capacitor and the storage capacitor will be charged and discharged many times. As the refresh rate of the display device increases, the charging and discharging of the liquid crystal capacitor and th...
