Specifically, the first driving module 15 and the second driving module 16 are connected to a first frame start signal terminal STV1 and a second frame start signal terminal STV2, respectively. In other words, time points at which the first driving module 15 and the second driving module 16 start to output scan signals in each frame of picture can be controlled separately, that is, in a manner of driving non-simultaneously on both sides, which is different from the simultaneous driving in the related art in which the same signal is inputted simultaneously on the left and right sides. Moreover, the non-simultaneous driving on both sides requires only a small area for arranging a GOA circuit, thereby making it possible to meet the requirement of achieving the narrow frame design.
In this embodiment, arranging alternately the first and second scan lines in the column direction may refer to arranging alternately every one row of the first scan line and every one row of the second scan line in the column direction, or arranging alternately every two rows of the first scan lines and every two rows of the second scan lines in the column direction. For the arranging alternately every one row of the first scan line and every one row of the second scan line in the column direction, it refer to a case that the one or more first scan lines are arranged in either one or more odd-numbered or even-numbered rows, and the one or more second scan lines are correspondingly arranged in either one or more even-numbered or odd-numbered rows in the column direction. This also applies to the one or more third scan lines 13 and the one or more fourth scan lines 14. For example, the one or more first scan lines 11 are one or more scan lines in one or more odd-numbered rows of the regular-shaped display area 1, and the one or more second scan lines 12 are one or more scan lines in one or more even-numbered rows of the regular-shaped display area 1; and the one or more third scan lines 13 are one or more scan lines in one or more odd-numbered rows of the first irregular-shaped display area 2, and the one or more fourth scan lines 14 are one or more scan lines in one or more even-numbered rows of the first irregular-shaped display area 2. Alternatively, the one or more first scan lines 11 are one or more scan lines in one or more even-numbered rows of the regular-shaped display area 1, and the one or more second scan lines 12 are one or more scan lines in one or more odd-numbered rows of the regular-shaped display area 1; and the one or more third scan lines 13 are one or more scan lines in one or more even-numbered rows of the first irregular-shaped display area 2, and the one or more fourth scan lines 14 are one or more scan lines in one or more odd-numbered rows of the first irregular-shaped display area 2.
The gate driving circuit provided in this embodiment can allow for the manner of non-simultaneous driving on both sides of the regular-shaped display area to be applied to the driving of the first irregular-shaped display area, thereby achieving the full display of the irregular-shaped screen. Moreover, such a manner of driving non-simultaneously on both sides can meet the requirement of achieving the narrow frame design.
Below, two implementations of the irregular-shaped display panel, i.e., including one irregular-shaped display area and including two irregular-shaped display areas, are described in detail by way of examples, in which the one or more first scan lines 11 are one or more scan lines in one or more odd-numbered rows of the regular-shaped display area 1, and the one or more second lines 12 are one or more scan lines in one or more even-numbered rows of the regular-shaped display area 1, the one or more third scan lines 13 are one or more scan lines in one or more odd-numbered rows of the first irregular-shaped display area 2, and the one or more fourth scan lines 14 are one or more scan lines in one or more even-numbered rows of the first irregular-shaped display area 2.

For specific gate driving methods and operation processes, reference may be made to the foregoing embodiments of the gate driving circuit, and details are not described herein again.
According to another embodiment of the present disclosure, there is further provided an array substrate that includes the gate driving circuit as described in any of the above embodiments.
According to a further embodiment of the present disclosure, there is further provided a display device that includes the gate driving circuit as described in any of the above embodiments.
The present application provides the gate driving circuit and its driving method, the array substrate and the display device. The gate driving circuit is used for driving the irregular-shaped display panel which includes the regular-shaped display area and the first irregular-shaped display area. The regular-shaped display area includes the one or more first scan lines and the one or more second scan lines arranged alternately in the column direction. The first irregular-shaped display area includes the one or more third scan lines and the one or more fourth scan lines alternately arranged in the column direction. The gate driving circuit includes the first driving module and the second driving module. The first driving module is configured to drive the one or more first scan lines, and the second deriving module is configured to drive the one or more second scan lines. Moreover, the one or more third scan lines are driven by the first driving module or the second driving module, and the one or more fourth scan lines are driven by the first driving module or the second driving module. With this technical solution, it is possible to allow the manner of non-simultaneous driving on both sides of the regular-shaped display area to be applied to the driving of the first irregular-shaped display area, thereby achieving the full display of the irregular-shaped screen. Moreover, such a manner of driving non-simultaneously on both sides can meet the requirement of the narrow frame design.
The various embodiments in the present specification are described in a progressive manner, and each embodiment focuses on differences from other embodiments. Detailed description of the same or similar parts of the embodiment may be seen from the other embodiments.

Moreover, the terms “comprise”, “include” or any other variants thereof are intended to be not exclusive, in order that the process, method, item or device comprising a series of elements shall encompass not only elements described herein but also other elements that are not listed explicitly, or further encompass the inherent elements of this process, method, item or device. Without further limitation, an element defined by the phase “comprising a . . . ” does not exclude the presence of additional identical elements in a process, method, item or device that includes the element described herein.
The gate driving circuit and its driving method, the array substrate and the display device provided in the present disclosure have been described in detail. In the present application, the specific embodiments are provided to describe the principle and the implementations of the present application. The descriptions of the embodiments as above are used only to help understanding the methods and main concept of the present application; meanwhile, modifications may be made by an ordinary person skilled in the art according to the concept of the present application within the scope of specific embodiments and applications. Therefore, the contents of the specification should not be constructed as any limitation on the present application.
