Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] The transistors used in all the embodiments of the present invention can be thin film transistors or field effect transistors or other devices with the same characteristics. In this embodiment, the connection mode of the drain and the source of each transistor can be interchanged, therefore, there is actually no difference between the drain and the source of each transistor in the embodiment of the present invention. Here, only to distinguish the two po...

Abstract

The invention discloses a shift register output control unit, a shift register and a drive method thereof and a grid drive device. The output control unit comprises N pull-up units, N pull-down units and N signal output ends. The nth pull-up unit is connected with a pull-up node, a high voltage source, an nth clock signal input end and the nth pull-down unit. The nth pull-down unit is connected with a pull-down node and a low voltage source. The connecting point of the nth pull-up unit and the nth pull-down unit is also connected with the nth signal output end. The output control unit is configured in a way that clock signals from N clock signal input ends are provided for the N signal output ends respectively under the control of voltage of the pull-up node and level of the output signals of the N signal output ends is pulled down under the control of the signals provided by the pull-down node, wherein N is an integer, and 2<=N<=4 and 1<=n<=N. Multiple rows of grid lines can be driven, and a situation that no interference exists among all outputs can be guaranteed.

Description

technical field [0001] The present disclosure relates to an output control unit of a shift register, a shift register, a driving method thereof, and a gate driving device. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) is widely used in various fields of production and life. When displaying, TFT-LCD drives each pixel in the display panel to display through a driving circuit. The driving circuit of TFT-LCD mainly includes gate driving circuit and data driving circuit. Wherein, the data driving circuit is used for sequentially latching the input data according to the timing of the clock signal and converting the latched data into analog signals to be input to the data lines of the display panel. The gate driving circuit is usually realized by a shift register, and the shift register converts the clock signal into an on / off voltage, which is respectively output to each gate line of the display panel. A gate line on the display panel is usu...
