Embodiment Construction

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0038] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the description in the accompanying drawings directions for the example described above. It will be appreciated that if the illustrated device is turned over so that i...

Abstract

The invention relates to the technical field of display, and provides a grid driving circuit and a driving method, an array substrate and a display device. The gate driving circuit includes a 4n-levelshift register unit and an n-level inversion unit. An inversion unit is provided for each adjacent quadrupole shift register unit, An (n+1) th stage inversion unit is arrange between that two shift register unit for inversely outputting the gate driving signals output by the two shift register unit in the reload picture stage and for inversely outputting the gate driving signals output by the twoshift register units in the normal picture stage. The two shift register units are a 4n +1 th stage shift register unit and a 4n +2 th stage shift register unit, or the 4n +2 th and 4n +3 th shift register units, or the 4n +3 th and 4n +4 th shift register units, or the 4n +1 th and 4n +4 th shift register units. The gate drive circuit can reduce the power of the source driver during the reload picture phase.

Description

technical field [0001] The present disclosure relates to the technical field of displays, and in particular to a gate drive circuit and a drive method, an array substrate, and a display device. Background technique [0002] Currently, the most commonly used liquid crystal display is a thin film transistor (Thin Film Transistor, TFT) liquid crystal display. The TFT liquid crystal display adopts a source driver (Source Driver) to provide a driving voltage corresponding to an image to be displayed to the data line, so as to drive the display panel to display images. [0003] In the related art, the display stage of the liquid crystal display generally includes a reload image stage and a normal image stage. In the phase of heavy image loading, the refresh rate of the liquid crystal display is high, so the load on the source driver is relatively large, which easily causes the temperature of the source driver to be too high. [0004] It should be noted that the information discl...
