Problems solved by technology

However, since the clock signal is carried out according to a certain timing, there is a certain time delay between the multiple transmission signals and scanning signals output by one GOA unit, which leads to poor accuracy of scanning signal output and poor picture display effect

Abstract

The embodiment of the invention discloses a scanning driving circuit capable of accurately outputting scanning signals, which comprises n scanning driving units which are sequentially arranged and cascaded, and each scanning driving unit is used for outputting two scanning signals at an interval of preset time. Each scanning driving unit comprises two pull-down time adjusting modules which are used for adjusting the time of the scanning signal output end from the time of outputting the scanning signal to the time of stopping outputting the scanning signal to be the same. By adjusting the voltage drop time of the two scanning signals output by each scanning driving unit, the ghosting phenomenon during image display is reduced, and the image display effect is improved. The embodiment of the invention further discloses an array substrate comprising the scanning driving circuit and a display terminal.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a scan driving circuit, an array substrate and a display terminal applied to a display panel. Background technique [0002] At present, most liquid crystal display panels adopt the gate driver on array (Gate Driver on Array, GOA) technology. The GOA technology uses the thin film transistor (Thin Film Transistor, TFT) liquid crystal display array process to manufacture the gate scanning drive circuit on the thin film transistor array. On the substrate, to realize the driving technology of progressive scanning, which has the advantages of reducing the production cost and realizing the narrow frame of the panel. [0003] Currently, among the cascaded GOA units, one GOA unit can output two or more cascading signals and scanning signals under the control of a clock signal (Clock, CLK). However, since the clock signal is carried out according to a certain timing, there is a...
