Problems solved by technology

[0004] In the above-mentioned GOA panel, there will be a thin-film transistor (Thin-Film Transistor, hereinafter referred to as TFT) threshold voltage drift phenomenon. At this time, in order to maintain the characteristics of the TFT, it is necessary to increase the size of the TFT. The load of the driving circuit increases, and the load of the GOA panel increases, thereby increasing the power consumption of the GOA panel

Abstract

The invention discloses a gate driving circuit, a display module and a displayer, which belong to the field of display and are designed for solving the problem of larger power consumption of the display module in the prior art. The gate driving circuit is used for driving a gate of a thin-film transistor corresponding to the connected a gate line. The gate driving circuit comprises at least two shifting registers which are connected in a step-by-step manner; each shifting register comprises a first output end and a second output end; the first output end is connected with an enabling signal input end of the next-step shifting register so as to output an enabling signal to the next-step shifting register; and the second output end is connected with the gate line so as to apply a gate driving signal of the thin-film transistor on the gate by the gate line.

Description

technical field [0001] The invention relates to the field of display, in particular to a gate drive circuit, a display module and a display. Background technique [0002] Liquid crystal displays have the advantages of light weight, thin thickness, and low power consumption, so they are widely used in electronic products such as televisions, mobile phones, and mobile phones. [0003] In an existing liquid crystal display, a gate drive circuit may be formed on an array substrate, thereby forming a panel of a gate drive on array substrate (Gate drive On Array, hereinafter referred to as GOA), that is, a GOA panel. Wherein, the gate drive circuit includes several cascaded shift registers, and the control signal will be attenuated between each stage of shift registers. [0004] In the above-mentioned GOA panel, there will be a thin-film transistor (Thin-Film Transistor, hereinafter referred to as TFT) threshold voltage drift phenomenon. At this time, in order to maintain the cha...
