In an embodiment, fig. 3 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 3, the non-display area further includes a fifth non-display area BA5, the fifth non-display area BA5 being adjacent to the third display area AA3 in the first direction a; the display panel further includes a driving chip IC located in the fifth non-display area BA5, the driving chip IC including a plurality of pins J, wherein one second control signal line C2 is electrically connected to one pin J, and one third control signal line C3 is electrically connected to one pin J. The number of the pins J is only schematically shown in the figure, and the data lines in the display panel also need to be connected to the pins to realize that the driving chip provides signals to the data lines. Only one first control signal line C1, one second control signal line C2, and one third control signal line C3 are schematically shown. The third control signal line C3 controls the third shift register VSR3 in the third non-display area BA3 by directly outputting a signal from the driving chip IC. After the driving chip IC outputs a signal to the first control signal line C1, the driving chip IC can control the first shift register VSR1 in the first non-display area BA1 and the second shift register VSR2 in the second non-display area BA2, and the second shift register VSR2 can be controlled without winding in the gap non-display area BAK, which is beneficial to saving the space of the gap non-display area BAK.

The center O of the driving chip IC is the geometric center of the driving chip IC. That is, the driving chip is not disposed in the middle of the fifth non-display area but disposed near the first non-display area in this embodiment, such a design can ensure that the length of the trace connected to the third control signal line led out from the driving chip pin is greater than the length of the trace connected to the first control signal line led out from the driving chip pin, so that the load on the third control signal line can be increased. According to the invention, because the lengths of the first control signal line and the third control signal line, the numbers of the shift registers electrically connected with the first control signal line and the third control signal line respectively and the like are different, the loads on the first control signal line and the third control signal line are different, and the design scheme of the invention can reduce the load difference between the first control signal line and the third control signal line and improve the uniformity of display.
In an embodiment, fig. 4 is a schematic view of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 4, the width d3 of the third control signal line C3 is smaller than the width d4 of the first control signal line C1. The load on the first control signal line and the load on the third control signal line are different due to the difference of the lengths of the first control signal line and the third control signal line, the number of shift registers electrically connected with the first control signal line and the third control signal line, and the like. When the width of the third control signal line is reduced, the sectional area of the third control signal line is correspondingly reduced, so that the resistance of the third control signal line is increased, the load on the third control signal line can be increased, the load difference between the first control signal line and the third control signal line is reduced, and the uniformity of display is improved.
In an embodiment, fig. 5 is a schematic view of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 5, the display panel includes a plurality of signal lines H extending in the second direction b, and the signal line H positioned in the first display area AA1 is connected to the first shift register VSR1 positioned in the first non-display area BA 1. Fig. 5 illustrates an example in which only one first shift register is connected to one signal line. Alternatively, one first shift register may be connected to two or more signal lines. In this embodiment mode, the first shift register provided in the first non-display region is connected to the signal line provided in the first display region. The first display area adopts a single-side driving mode to realize display, and a shift register is not arranged in a notch non-display area adjacent to the first display area, so that the space of the notch non-display area can be saved. Meanwhile, a second control signal line connected with a second shift register in the second non-display area is connected to a first control signal line in the first non-display area through a connecting line, and a winding wire connected with the control signal line is not required to be arranged in the gap non-display area, so that the space of the gap non-display area can be further saved, and the narrowing of the gap non-display area is facilitated.
In an embodiment, fig. 6 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present disclosure. As shown in fig. 6, both ends of the signal line H positioned in the second display area AA2 are connected to the first shift register VSR1 and the second shift register VSR2, respectively; both ends of the signal line H positioned in the third display area AA3 are connected to the first shift register VSR1 and the third shift register VSR3, respectively.

The first display area adopts a unilateral driving mode to realize display, the second display area and the third display area both adopt a bilateral driving mode to realize control over the signal wire, and a shift register is not arranged in a gap non-display area adjacent to the first display area, so that the space of the gap non-display area can be saved. Meanwhile, a second control signal line connected with a second shift register in the second non-display area is connected to a first control signal line in the first non-display area through a connecting line, and a winding wire connected with the control signal line is not required to be arranged in the gap non-display area, so that the space of the gap non-display area can be further saved, and the narrowing of the gap non-display area is facilitated.
In some embodiments, at least two signal lines arranged in sequence in the first direction are connected to the same shift register. Fig. 7 is a schematic diagram of another alternative implementation of the display panel according to the embodiment of the present invention. As shown in fig. 7, only two signal lines H sequentially arranged in the first direction a are connected to the same shift register as an example.

Meanwhile, the second control signal line C2 connected to the second shift register VSR2 in the second non-display area BA2 is connected to the first control signal line C1 located in the first non-display area BA1 through the connection line L, and the BAK in the gap non-display area also does not need to be provided with a winding wire connected to the control signal line, so that the space of the gap non-display area BAK can be further saved, and the narrowing of the gap non-display area BAK is facilitated.
