Problems solved by technology

[0004] figure 1 It is a structural schematic diagram of a bilaterally driven GOA circuit in the prior art, such as figure 1 As shown, the current bilateral drive GOA circuit is usually connected to the full-on module and the full-off module on the left and right sides of the display panel respectively, so as to realize the full-on function and the full-off function of the GOA circuit, which will make the GOA The structure of the circuit is complex and occupies a large area, which makes the width of the display panel larger, which is not conducive to the realization of a display panel with a narrow frame

Embodiment Construction

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0024] In all embodiments of the present application, in order to distinguish the two poles of the TFT except the gate, one pole is called the source, and the other pole is called the drain. Since the source and drain of a thin film transistor are symmetrical, their source and drain are interchangeable. According to the form in the attached drawing, it is stipulated that the middle terminal of the thin film transistor is the gate, the signal input terminal is the source, and the...

Abstract

The invention provides a GOA circuit and a display panel, and the GOA circuit is different from a conventional GOA circuit in which a full-open module and a full-close module need to be connected to the left side and the right side of the display panel respectively to achieve a full-open function and a full-close function. According to the GOA circuit, in GOA sub-circuits on the left side and theright side of a display panel, only one GOA unit in two GOA units on the same level is connected with a full-open module, and only one GOA unit is connected with a full-closed module, so that the number of the full-open modules and the number of the full-closed modules required by the GOA circuit are both reduced by half; when the GOA circuit is applied to a display panel of a bilateral driving line-by-line scanning framework, the area occupied by the GOA circuit on the display panel can be reduced on the premise of not influencing a full-on function and a full-off function, and the display panel with high resolution and a narrow frame can be realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a GOA circuit and a display panel. Background technique [0002] GOA (Gate Driver On Array) technology refers to integrating the gate driver circuit of the display panel on the glass substrate to realize the scanning drive of the display panel. GOA technology can reduce the bonding process of external ICs and reduce product costs. It is suitable for Make narrow bezel display products. [0003] The GOA circuit includes a plurality of cascaded GOA units, and each level of GOA units outputs scan signals through scan lines to drive the thin film transistors of a corresponding row of pixels to turn on or off. The GOA circuit has an All Gate on function and an All Gate off function. The All Gate function means that when the display panel is turned off or turned on, each level of GOA unit simultaneously outputs a high-potential scanning signal to Turn on the thin film trans...
