Abstract

The embodiment of the invention discloses a scanning driving circuit which comprises n scanning driving units and two virtual scanning driving units which are sequentially arranged and cascaded, and each scanning driving unit is used for outputting two scanning driving signals at an interval of preset time. The two virtual scanning driving units are respectively connected with the (n-1) th scanning driving unit and the nth scanning driving unit, and respectively output a first level transmission signal to the (n-1) th scanning driving unit and the nth scanning driving unit; the nth scanning driving unit and the (n-1) th scanning driving unit are controlled to respectively output stage transmission signals for driving other scanning driving units, and due to the fact that one virtual scanning driving unit can control output of two stage transmission signals at the same time, the number and occupied space of the virtual scanning driving units are effectively reduced. 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 G Driver on Array (GOA) technology of the array substrate. 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, a dummy GOA unit (Dummy GOA) is generally used to be cascaded after the last GOA unit to pull down the high-level signal in the last GOA unit. However, the virtual GOA unit used in this method occupies a large space, compresses the wire on array...
