The data lines receive data signals and control the driving voltage of each sub-pixel, so that the rotation angle of the liquid crystal is controlled, and different light transmittance is realized. The scanning signal is provided by the gate driving device. The grid driving device generates a plurality of scanning signals and transmits the scanning signals to the scanning lines according to a certain sequence so as to sequentially start the thin film transistor elements.

Further, the non-display region BB includes a normal non-display region BB0 and a shaped non-display region BB1, wherein a portion of the non-display region BB located between the first boundary L11 and the first edge L21, and a portion located between the second boundary L12 and the second edge L22 are a normal non-display region BB 0; the portion of the non-display region BB located between the shaped boundary L13 and the shaped edge L23 is a shaped non-display region BB 1.
In this embodiment, the array substrate 01 has a rounded rectangle, or the display area AA of the array substrate 01 has a rounded rectangle. The array substrate 01 comprises an upper end and a lower end which are positioned in the column direction D1, and a left side and a right side which are positioned in the row direction D2, wherein the regular non-display regions BB0 of the array substrate 01 are respectively positioned at the left side, the right side, the upper end and the lower end of the array substrate 01, and the irregular non-display regions BB1 are arranged adjacent to four cutting angles of the array substrate 01 and are respectively positioned between two adjacent regular non-display regions BB 0.
The array substrate 01 further includes a pixel array disposed in the display area AA, wherein the pixel array includes a plurality of data lines DL and a plurality of scan lines GL, the data lines DL and the scan lines GL are arranged in parallel to define a plurality of pixels, each pixel includes a display driving switch (not shown), for example, a thin film transistor having three terminals, i.e., a gate terminal, a source terminal and a drain terminal, and a pixel electrode (not shown), and the pixel electrode is connected to the source terminal (or the drain terminal) of the thin film transistor. The pixel array may include, for example, a plurality of rows and a plurality of columns of pixels, the drain (or source) of the thin film transistor in each column of pixels may be connected to, for example, the same data line DL, from which the data signal is provided to the pixels in the corresponding column, and the gate of the thin film transistor in each row of pixels may be connected to, for example, the same scan line GL, from which the scan signal is provided to the pixels in the corresponding row.
In the present embodiment, each data line DL extends in the column direction D1 and is arranged in the row direction D2, and each scan line GL is arranged in the column direction D1 and extends in the row direction D2. The gate driving circuit 10 is located in the non-display area BB on one side of the array substrate 01, and each of the scanning lines GL is electrically connected to a corresponding interface in the gate driving circuit 10. As to the specific structure of the gate driving circuit 10, please refer to fig. 2 and 3, which can be, for example: the gate driving circuit 10 includes a plurality of shift registers including a plurality of normal shift registers 11 and at least one dummy shift register Dum ASG, wherein each normal shift register 11 is connected to one row of scanning lines GL, so that scanning signals can be sequentially input to the scanning lines GL to realize progressive scanning of the scanning lines GL.
Unlike the conventional shift register 11, the dummy shift register Dum ASG does not connect the scan lines GL of the display area AA and does not supply the scan signals to the scan lines GL of the display area AA. In the gate driving circuit 10, a plurality of shift registers are electrically connected to each other, and in the present embodiment, the plurality of conventional shift registers 11 include a plurality of stages of shift registers, for example: ASG 1 is the first stage shift register, ASG 2 is the second stage shift register, ASG 3 is the third stage shift register, ASG 4 is the fourth stage shift register, and so on. The first stage shift register ASG 1 is electrically connected to the dummy shift register Dum ASG, and receives the signal transmitted from the dummy shift register Dum ASG, and the first stage shift register ASG 1 is electrically connected to the second stage shift register ASG 2, and transmits the signal to the second stage shift register ASG 2. When a termination signal is given to the dummy shift register Dum ASG, the second shift register ASG 2 receives the signal sent from the first shift register ASG 1, transmits the signal to the next shift register (i.e., the third shift register ASG 3), and gives a termination signal to the previous shift register (i.e., the first shift register ASG 1), and so on.
In an embodiment of the present invention, two dummy shift registers Dum ASG, which are the first dummy shift register 111 and the second dummy shift register 112, respectively, may be included. The input end of the first dummy shift register 111 is connected to an integrated driving circuit (not shown in the figure) and receives a start pulse signal transmitted from the integrated driving circuit, the output end of the first dummy shift register 111 is connected to one end of the first stage shift register G1, and the output end of the second dummy shift register 112 is connected to one end of the nth stage shift register. For example, if there are N shift registers in the gate driving circuit 10, the end of the gate driving circuit 10 is connected as shown in fig. 3, and one end of the gate driving circuit 10 is connected to the output end of the second dummy shift register. In fig. 3, two nth stage shift registers (ASG N and ASG N-1) are connected to the output terminal of the second dummy shift register 112, and the output terminal of the second dummy shift register 112 is connected to the driving ic for receiving the start pulse signal transmitted from the driving ic. This way can compromise the forward scanning and the reverse scanning of array substrate.
In general, the plurality of scan lines GL connected to the gate driving circuit 10 are uniformly distributed in the entire display area AA, the lengths of the plurality of scan lines GL are substantially equal, and the number of pixels connected to each scan line GL is substantially equal, so that the resistances and coupling capacitances of the plurality of scan lines GL are substantially equal, the loads of the regular shift registers 11 in the gate driving circuit 10 are also substantially equal, and in order to match the loads of the dummy shift registers Dum ASG with the loads of the regular shift registers 11, in this embodiment, the array substrate 01 further includes at least one dummy scan line Dum G connected to the corresponding dummy shift register Dum ASG.
In the embodiment of the invention, the gate driving circuit 10 is located in the non-display area BB on one side of the array substrate 01, the dummy shift register Dum ASG and the dummy scan line Dum G are all located in the special-shaped non-display area BB1, and the dummy scan line Dum G is located between the display area AA and the dummy shift register Dum ASG.
The dummy scan lines Dum G may be configured as S-shaped traces as shown in fig. 4, for example, so that all the traces may be routed in the special-shaped non-display area BB1 without extending into the normal non-display area BB0 at the upper and lower ends of the array substrate 01 under the condition that the traces have a sufficient length or sufficient resistance and coupling capacitance, so as to reduce the area of the non-display areas BB at the upper and lower ends of the array substrate 01, which is beneficial for implementing a narrow bezel design. The S-shaped wiring comprises a plurality of sections of wiring which are connected with each other, the length of each section of wiring can be set according to the shape of the special-shaped non-display area BB1, or can be set according to the boundary shape of the display area AA, which is adjacent to the special-shaped non-display area BB1, so that the space of the special-shaped non-display area BB1 is fully utilized, the space area occupied by the dummy scanning line Dum G is reduced, and the narrow frame is facilitated.
Taking the second dummy shift register 112 as an example, in the present embodiment, the second dummy shift register 112 is routed in an S-shape and is entirely located in the irregular non-display area BB1 at the lower left corner of the array substrate 01. Further, the array substrate 01 further includes a plurality of data signal leads Dx located in the non-display area, and respectively electrically connected to the plurality of data lines DL in a one-to-one correspondence, and providing data signals to the data lines DL. The plurality of data signal leads Dx1, which pass through the non-display BB1 and are electrically connected to the data driving circuit, are provided. The dummy scan line Dum G is disposed to be insulated and overlapped with at least a portion of the first data signal lead Dx1, and a coupling capacitance is generated between the dummy scan line Dum G and the first data signal lead Dx1 overlapped therewith. By increasing the length of the dummy scan line Dum G, the resistance of the dummy scan line Dum G can be increased, and the overlapping area between the dummy scan line Dum G and the data signal lead Dx can be increased, thereby increasing the coupling capacitance between the dummy scan line Dum G and the data signal lead Dx. Since the load is proportional to the resistance and the coupling capacitance, the load of the dummy scan line Dum G increases accordingly. Since the dummy scan line Dum G is connected to the dummy shift register, increasing the load of the dummy scan line Dum G is equivalent to increasing the load of the dummy shift register, so that the load of the dummy shift register matches the load of the conventional shift register. The charging state of the pixels in the display area of the data line can be ensured to be consistent, and the display effect is improved.
In an embodiment of the invention, the array substrate 01 includes a first metal layer M1 and a second metal layer M2 stacked in sequence, wherein the dummy scan lines Dum G and GL are formed on the first metal layer M1, and the data signal leads Dx and DL are formed on the second metal layer M2.
Fig. 5 is another routing manner of the dummy scan lines according to an embodiment of the present invention, in this embodiment, each dummy scan line Dum G includes a second portion Dum Gy close to the display area AA and a first portion Dum Gx far away from the display area AA, and the second portion Dum Gy is connected to the corresponding dummy shift register Dum ASG through the first portion Dum Gx. The second portion Dum Gy is disposed to be insulated and overlapped with at least a portion of the first data signal lead Dx1, and the width of the second portion Dum Gy in the column direction D1 is greater than the width of the first portion Dum Gx in the column direction.
By increasing the width of the portion of the dummy scan line Dum G overlapping the data signal lead Dx, the overlapping area between the dummy scan line Dum G and the data signal lead Dx can be increased, and the coupling capacitance between the dummy scan line Dum G and the data signal lead Dx is increased, so that the load of the dummy scan line Dum G is correspondingly increased. Because the dummy scanning line Dum G is connected with the dummy shift register, the load of the dummy scanning line Dum G is increased, which is equivalent to the increase of the load of the dummy shift register, so that the load of the dummy shift register is consistent with the load of the conventional shift register, the charging state of the data line to the pixels in the display area can be further ensured to be consistent, and the display effect is improved.
Fig. 6 is another routing manner of the dummy scan line according to the embodiment of the present invention, in this embodiment, the dummy scan line Dum G includes a second portion Dum Gy close to the display area AA and a first portion Dum Gx far away from the display area AA, and the second portion Dum Gy is electrically connected to the corresponding dummy shift register through the first portion Dum Gx. Wherein the second portion Dum Gy is disposed to be insulated and overlapped with at least a portion of the first data signal lead Dx1, wherein the second portion Dum Gy includes a plurality of branches extending in the row direction D2, and one end of all the branches is electrically connected to one end of the first portion Dum Gx away from the dummy shift register. Therefore, the length of the dummy scan line Dum G and the overlapping area between the dummy scan line Dum G and the data signal lead Dx can be increased, and the resistance of the dummy scan line Dum G and the coupling capacitance between the dummy scan line Dum G and the data signal lead Dx are increased, which is equivalent to increasing the load of the dummy shift register, so that the load of the dummy shift register is matched with the load of the conventional shift register.
Alternatively, the gate driving circuit 10 may include at least two shift register groups, each shift register group includes a plurality of shift registers electrically connected to each other, and the array substrate includes at least two dummy scan lines electrically connected to the at least two shift register groups, respectively. The at least two dummy scan lines are all located in the irregular non-display area BB1 of the array substrate 01. For example, when the gate driving circuit is a multiphase shift register, all the dummy scan lines connected to a plurality of required dummy shift registers are located in the irregular non-display area BB1, which can greatly reduce the area of the non-display area and is beneficial to narrow the frame compared with a conventional non-display area where all the dummy scan lines penetrate through the upper and lower ends of the array substrate.
Alternatively, as shown in fig. 7, two shift register groups (a first shift register group 101 and a second shift register group 102) of the gate driving circuit 10 are located on the left and right sides of the display area AA in the row direction D2, and the number of shift registers in the two shift register groups (the first shift register group 101 and the second shift register group 102) is equal, which may be: the gate driving circuit 10 is located at the left and right sides of the display area AA in the row direction D2, and each side includes a plurality of shift register sets. Optionally, the shift register groups on the same side are connected to the same dummy shift register Dum ASG, the shift register groups on different sides are connected to different dummy shift registers Dum ASGs, and the dummy scan lines connected to the two different dummy shift registers Dum ASGs are respectively located in the irregular non-display areas BB1 on both sides of the array substrate. The dummy scanning lines can be completely wired in the special-shaped non-display area without extending to the conventional non-display areas at the upper end and the lower end of the array substrate under the condition that the dummy shift register is ensured to have enough load, so that the area of the non-display areas at the upper end and the lower end of the array substrate can be reduced, and the narrow-frame design is favorably realized.
Secondly, the invention further provides a display panel comprising the array substrate provided by any one of the embodiments. The display panel may be a liquid crystal display panel, an OLED or electrophoretic display panel, or the like. Taking the liquid crystal display panel as an example, when the display panel is a liquid crystal display panel, the display panel further includes a color film substrate arranged opposite to the array substrate, and a liquid crystal layer sealed between the array substrate and the color film substrate, and the array substrate and the color film substrate are sealed into a box by a frame sealing adhesive arranged in the peripheral non-display area.
In addition, an embodiment of the present invention further provides a display device, including any one of the display panels provided in the above embodiments. Referring to fig. 8, fig. 8 is a schematic diagram of a display device according to an embodiment of the present invention, and the display device 100 includes any one of the display panels according to the embodiment of the present invention. The display device 100 provided by the embodiment of the invention can be any electronic product with a display function, including but not limited to the following categories: the mobile terminal comprises a television, a notebook computer, a desktop display, a tablet computer, a digital camera, a mobile phone, an intelligent bracelet, intelligent glasses, a vehicle-mounted display, medical equipment, industrial control equipment, a touch interaction terminal and the like.
By the embodiment, the display panel and the display device provided by the embodiment of the invention have the following beneficial effects: the array substrate comprises a display area and a non-display area surrounding the display area, wherein the non-display area comprises a special-shaped non-display area and is positioned between a special-shaped boundary of the display area and a special-shaped edge of the array substrate; the dummy scanning lines of the array substrate are positioned in the special-shaped non-display area, so that the occupied space of the dummy scanning lines in the non-display area can be reduced, the area of the non-display area of the array substrate is reduced, and the narrow frame of the display device is facilitated.
