Fig. 1 is a schematic diagram of an exemplary liquid crystal display using Gate Driver on array (GOA) technology, in which a Gate Driver circuit 170 replaces a conventional Gate Driver chip, and one-sided Gate Driver circuits 170 are mainly used to drive scan lines in a display area 120 of the display panel 110, as shown in fig. 2, each Gate Driver circuit 170 includes a plurality of Gate Driver circuit units, each GOA unit has a positive phase clock signal Input terminal CLK, a negative phase clock signal Input terminal CLKB, and a low voltage signal Input terminal Vss, and each GOA unit further has an Input terminal Input, an Output terminal Output, and a Reset terminal Reset. The output of each row of GOA units is used as the input of the next row of GOA units and as the reset terminal of the previous row of GOA units, and the Start Vertical (STV) signal is used as the input for the first row of GOA units.
As shown in fig. 3, which is a schematic diagram of an exemplary dual-side driving display panel, when a large-sized product is driven by using GOA, since the load of the gate driving circuit 170 is large, a dual-side driving mode is mostly used, and two gate driving circuits are disposed on two sides of one display panel. However, as the size is further increased, the dual-edge drive may not meet the demand.
Based on a bilateral driving mode, in an unpublished scheme, a scheme of splicing screens exists to realize large size, namely, a plurality of display screens are spliced together after being respectively packaged, and linkage display among the plurality of display screens is realized through an external grid driving circuit.
However, the single screen package must have a frame that is difficult to reduce to a small enough width due to mechanical structure, so even if the package is good, there are very visible black stripes between the tiled screens.
The invention is described in detail below with reference to the figures and alternative embodiments.
Fig. 4 is a schematic diagram of a display panel including a plurality of display regions according to the present invention, and referring to fig. 4, the present invention discloses a display panel 110, including: a plurality of display regions 120, the plurality of display regions 120 being arranged M × N and formed on the same substrate 160; and a first gate driving module 130 disposed between two adjacent display regions 120 to drive the two adjacent display regions 120; wherein M is the number of the display regions 120 in each column in the first direction, N is the number of the display regions 120 in each row in the second direction, the first direction and the second direction are perpendicular, M is a positive integer greater than or equal to 1, and N is a positive integer greater than or equal to 2. The value of M N is a positive integer greater than or equal to 2, namely, at least two display areas are provided.
The first direction refers to an extending direction of the data lines in the display region, but may be a direction of the scan lines in the display region.
Compared with the scheme that the scanning lines are driven by using the gate driving module from the side edge of the display panel, the first gate driving module 130 is arranged between the two adjacent display areas, so that the distance from the far end part of the scanning line in the display area 120 to the first gate driving module is greatly shortened, the load of the first gate driving module 130 is also greatly reduced, the scanning waveform of the end part of the scanning line far away from the first gate driving module is improved, the problem that the switching action cannot be well completed due to the poor scanning waveform of the end part is avoided, and the size of the display panel is further increased; in addition, compared with a plurality of display screens, each display screen needs to be packaged independently and then spliced to form the display panel, as each display area is formed on the same substrate, the distance between two different display areas can be reduced as much as possible, and the width of a black frame or a black stripe of the two display areas can be reduced.
The first gate driving module is formed on the display panel by using a GOA (gate driver on array) technology, so that the width of a black frame or a black stripe can be further reduced while materials are saved, the manufacturing process is reduced, the production cost is reduced.

The separate driving means that the display of the first display region 121 and the second display region 122 can be controlled separately, and of course, when the signals of the two are linked or shared, the first gate driving module 130 drives the first display region 121 and the second display region 122 simultaneously.
The first gate driving module 130 may adopt the exemplary GOA circuit shown in fig. 2 and 3, or may adopt a bidirectional gate driving unit capable of simultaneously driving the display regions on both sides; if the bidirectional gate driving unit is adopted, an output line on one side is reserved, if a proper mode is adopted, the output line reserved by the bidirectional gate driving unit can be connected to the corresponding scanning line in an assembling and splicing mode, and meanwhile, the size of the display panel is further increased.

In this embodiment, the input signals are common, that is, the corresponding input signals are common in wiring, which can reduce the space required for wiring, thereby reducing the width of the non-display area between the first display area and the second display area.
The display panel is provided with a group of input signals including a normal phase clock signal CLK, a reverse phase clock signal CLKB, a power supply signal Vss and a frame start signal STV corresponding to the bidirectional gate driving unit, and comprises two groups of scanning signals to drive scanning lines of a first display area and a second display area respectively; the first display area and the second display area are driven by the same frame starting signal STV, so that the driving synchronism can be ensured; the corresponding bidirectional gate driving unit includes a normal phase clock signal Input terminal CLK for receiving the normal phase clock signal CLK, the inverted phase clock signal CLKB, the power supply signal Vss and the frame start signal STV, an inverted phase clock signal Input terminal CLKB and a power supply Input terminal Vss, and further includes a first Output terminal Output L, a first Reset terminal Reset L and a first Input terminal Input L corresponding to the first display region, and a first Output terminal Output R, a first Reset terminal Reset R and a second Input terminal Input R corresponding to the second display region, wherein the first Input terminal Input L and the second Input terminal Input R are used for receiving the frame start signal STV.
Of course, the present invention may also share a set of positive phase clock signal CLK, negative phase clock signal CLKB, and power signal Vss in the bidirectional gate driving units of the two display regions, and then set the first frame start signal STV1 corresponding to the first display region, and set the second frame start signal STV2 corresponding to the second display region, so as to select the first display region and the second display region to display a picture together, or display different pictures respectively, or even control only one of the display regions to display a picture.
In one embodiment, the scanning lines of the first display area and the second display area are communicated; the first grid driving module comprises a bidirectional grid driving unit, the bidirectional grid driving unit receives a group of input signals and outputs a group of scanning signals to drive scanning lines of the first display area and the second display area simultaneously; and the access position of the output end of the bidirectional gate driving unit is positioned at the connection position of the scanning lines of the first display area and the second display area. In this embodiment, the scan lines in the adjacent display regions may be connected, and the bidirectional gate driving unit accesses the scan lines at the connection of the first display region and the second display region to input the frame start signal from a position between both ends of the scan lines, thereby realizing bidirectional driving in the case of only one set of scan signals, i.e., achieving the purpose of simultaneously driving the first display region and the second display region.
In one embodiment, the scanning lines of the first display area and the second display area are not communicated; the first gate driving module comprises a first unidirectional gate driving unit and a second unidirectional gate driving unit, the first unidirectional gate driving unit receives a group of input signals and outputs a group of scanning signals to drive the first display area, and the second unidirectional gate driving unit receives another group of input signals and outputs another group of scanning signals to drive the second display area. In this embodiment, the first gate driving module may also adopt a GOA circuit as shown in fig. 2, each group of input signals corresponds to a group of scan signals to drive the first display area or the second display area, and one gate driving unit corresponds to a scan line of one display area, so as to ensure sufficient driving capability and achieve better driving effect.
As shown in fig. 10, N display regions arranged in each row of the display panel in the second direction are, from one end to the other end, a first display region 123, a second display region … …, and an nth display region 124; n-1 first grid driving modules are arranged in each row in the second direction and are respectively and correspondingly arranged between two adjacent display areas; the display panel further includes two second gate driving modules 140, two of the second gate driving modules 140 are disposed in each row in the second direction, and are respectively disposed on the side of the first display region far from the nth display region, and the side of the nth display region far from the first display region.

Of course, the second gate driving module may be longer than a single display region in the first direction, for example, the second gate driving module may be disposed corresponding to two adjacent display regions in the first direction, or even the second gate driving module corresponding to the side length of the display panel may be disposed to drive all the display regions on one side of the display panel.
All the display areas and the first gate driving module are formed on the same substrate through a common process. The first gate driving module is formed between the two adjacent display areas in a GOA circuit mode, and the routing corresponding to the gate driving module and the routing in the display areas are formed through a common manufacturing process, so that the manufacturing process can be saved, the production efficiency is improved, and the material waste is reduced; moreover, the production cost is reduced, and the narrow frame is realized.

The display panel comprises two display areas, a first grid driving module is arranged between the two display areas, meanwhile, a second grid driving module is respectively arranged on the side edges, far away from the opposite side, of the two display areas, certainly, the value of N can be 1, and the value of M can be 2.
