The GOA circuit includes multiple GOA units cascaded. At present, each GOA unit of the GOA circuit is used to output a gate drive signal to control a row of pixel units of the display panel for display. Since the GOA circuit still uses a large number of thin film transistors , so it is not conducive to shrinking the lateral bezels of the display panel

Embodiment Construction
[0034] 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.
[0035] In all the embodiments of the present application, two electrodes other than the gate of the transistor are distinguished, one of which is called the source, and the other is called the drain. Since the source and drain of a transistor are symmetrical, its source and drain are interchangeable. According to the form in the accompanying drawings, it is stipulated that the middle terminal of the transistor is the gate, the signal input terminal is the source terminal, and th...

The invention provides a GOA circuit and a display panel. A forward and reverse scanning module and a first latch module of each GOA unit are shared. A second latch module comprises a plurality of NAND gate circuits which are connected in parallel; a buffer output module comprises a plurality of buffer output circuits connected in parallel, the plurality of NAND gate circuits are connected with the plurality of buffer output circuits in a one-to-one correspondence manner, and each buffer output circuit can output a gate scanning signal, so each stage of GOA unit can output a plurality of gatescanning signals. Each stage of GOA unit of the GOA circuit is equivalent to a plurality of cascaded GOA units in a traditional GOA circuit. According to the GOA circuit, a plurality of grid scanningsignals can be output in sequence according to the time sequence, so each stage of GOA unit can control a plurality of rows of pixel units of the display panel to display, the number of thin film transistors included in the GOA circuit is reduced, the wiring space of the GOA circuit is saved, and the frame size of the display panel is further reduced.
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 integrates the gate drive circuit of the display panel on the glass substrate to form a scan drive for the display panel. GOA technology can reduce the bonding process of external ICs, reduce product costs, and is more suitable for making display products with narrow borders or no borders. [0003] Because the GOA circuit is integrated on the glass substrate, it needs to occupy the areas on both sides of the display panel. With the continuous upgrading of consumption, the requirements for display products with narrow borders or no borders are also getting higher and higher. The GOA circuit includes a plurality of cascaded GOA units. At present, each GOA unit of the GOA circuit is used to output a gate drive signal to control a row of pixel units of the display panel ...
