Specifically, referring to fig. 4, the display panel 10 includes a driving signal line 230, and the driving signal line 230 is electrically connected to the driving circuit 200 and provides a corresponding driving signal to the driving circuit 200. For example, the driving signal line 230 may include a high potential (VGH) driving signal line, a low potential (VGL) driving signal line, a first clock driving signal line (CK), and a second clock driving signal line (XCK), and the driving circuit 200 may generate a scan control signal or a light emission control signal to the pixel circuits in the display area according to the driving signal supplied from the driving signal line 230, so that the pixel circuits supply driving currents to the corresponding light emitting elements according to the scan control signal or the light emission control signal, thereby realizing a normal display function of the display area.

Specifically, the driving circuit 200 may include a scan driving circuit and a light emission control driving circuit, and the display panel 10 may be provided with a plurality of driving circuits according to different pixel circuits in the sub-pixels. If the pixel circuit includes a transistor whose low level is controlled to be on, the effective enabling level provided by the driving circuit 200 connected thereto is low, and if the pixel circuit includes a transistor whose high level is controlled to be on, the effective enabling level provided by the driving circuit 200 connected thereto is high, and the type of the driving circuit 200 can be adaptively adjusted according to the type of the transistor in the pixel circuit.

Further, the setting relationship between the driving unit and the pixel circuit may be a "one-drive-multiple" or "one-drive-one" mode. The "one-drive-multiple" means that one driving unit is electrically connected with the plurality of rows of pixel circuits, i.e. one driving unit drives the plurality of rows of pixel circuits; and "a drive" means that one driving unit is electrically connected to one row of pixel circuits, i.e., one driving unit drives one row of pixel circuits. I.e. the driving means of the driving unit has a variety of driving modes.

Further, the driving circuit 200 may be disposed on one side of the sub-pixel, or may be disposed on two sides of the sub-pixel, that is, the driving circuit 200 may be driven on one side or two sides, and in the case of two sides driving, may be driven in a cross manner, that is, the flexibility of the setting position of the driving circuit 200 is reflected. Meanwhile, the setting of the driving circuit 200 can be adaptively adjusted according to the region. For example, a single-sided drive may be employed in the first region 10A and a double-sided drive may be employed in the second region 10B.

Further, the driving signal line 230 includes a first signal line subsection 231 for providing a driving signal to the first driving unit 211, and the driving signal line 230 includes a second signal line subsection 232 for providing a driving signal to the second driving unit 221.

Further, referring to fig. 4, the projection length of the third signal line sub-section 233 in the second direction Y for connecting the first signal line sub-section 231 and the second signal line sub-section 232 is L1, since the first signal line sub-section 231 is located in the first area 10A, the second signal line sub-section 232 is located in the second area 10B, and the dimensions of the first area 10A and the second area 10B in the second direction Y are different, a certain length exists in the second direction Y of the third signal line sub-section 233, that is, the projection length of the third signal line sub-section 233 in the second direction Y is greater than zero, and the driving circuits of the areas with different dimensions and positions of the display panel 10 can all receive the driving signals, so as to ensure the display effect of the display panel 10.

It should be noted that, in fig. 4, taking the first signal line sub-segment 231 located in the first non-display sub-area 110A and the second signal line sub-segment 232 located in the fourth non-display sub-area 120A as an example, there is flexibility based on the arrangement positions of the first driving circuit 210 and the second driving circuit 220, and thus, there is flexibility in the arrangement of the driving signal lines 230 electrically connected to the driving circuit 220. For example, the first signal line sub-section may also be located in the third non-display sub-section 110C, and the second signal line sub-section may also be located in the fifth non-display sub-section, which arrangement is described in the following embodiments.

It should be noted that, in fig. 4, only one trace is used to represent the driving signal lines 230, and there are a plurality of actual driving signal lines 230 of the display panel 10, and the number of driving signal lines 230 is not particularly limited in the embodiment of the present invention.

It should be noted that the driving signal line may be located on a side of the driving circuit away from the display area of the display panel, that is, closer to a boundary of the non-display area than the driving circuit (not shown). Or, in order to reduce the area of the non-display area, the driving signal line and the driving circuit may be disposed in a stacked manner on the film layer (as shown in fig. 4), that is, in the thickness direction of the display panel, or in the light emitting direction of the display panel, the orthographic projection of the driving signal line on the substrate of the display panel and the orthographic projection of the driving circuit on the substrate at least partially overlap, so that the area of the non-display area can be reduced, the occupation ratio of the display area can be improved, and the display effect of the display panel can be improved. The embodiment of the present invention is not limited to the relative positional relationship between the driving signal line and the driving circuit, and fig. 4 only illustrates an example in which the driving signal line and the driving circuit are stacked on the film layer.

Further, the driving circuit 200 may also be disposed in the sixth non-display sub-area 120C, which represents a flexible arrangement of the driving circuit 200.

Alternatively, referring to fig. 5, the third signal line sub-section 233 may be disposed in the second display area 121, that is, while the driving signal line 230 is guaranteed to provide the driving signals for the first driving circuit 210 and the second driving circuit 220, the sixth non-display area 120C may not be required to be disposed in the second non-display area 120, which is equivalent to increasing the display area of the second display area 121, and improving the user experience.

It should be noted that the first non-display sub-area 110A and the fourth non-display sub-area 120A are located on the same side of the display panel 10, and it should be understood that, taking the entire display panel as an example, the first non-display sub-area 110A and the fourth non-display sub-area 120A are located on the same side of the display panel 10, and fig. 4 and 5 each illustrate that the first non-display sub-area 110A and the fourth non-display sub-area 120A are located on the left side of the display panel 10.

Fig. 6 is a schematic structural view of another display panel according to an embodiment of the present invention, fig. 7 is a schematic structural view of another display panel according to an embodiment of the present invention, fig. 8 is a schematic structural view of another display panel according to an embodiment of the present invention, and referring to fig. 6 to 8, the first driving circuit 210 is at least partially located in the third non-display sub-area 110C, the second driving circuit 220 is at least partially located in the fifth non-display sub-area 120B, and the third non-display sub-area 110C and the fifth non-display sub-area 120B are located on the same side of the display panel; the first signal line subsection 231 is at least partially located in the third non-display sub-area 110C; the second signal line subsection 232 is at least partially located in the fifth non-display sub-area 120B.

Further, the first driving circuit 210 disposed in the third non-display sub-area 110C provides driving signals through the first signal line sub-section 231, i.e. the first signal line sub-section 231 is at least partially disposed in the third non-display sub-area 110C, and the second driving circuit 220 disposed in the fifth non-display sub-area 120B provides driving signals through the second signal line sub-section 232, i.e. the second signal line sub-section 232 is at least partially disposed in the fifth non-display sub-area 120B. The projection length of the third signal line sub-segment 233, which connects the first signal line sub-segment 231 and the second signal line sub-segment 232, in the second direction Y is greater than zero, so that the driving circuits of the areas of different sizes and positions of the display panel 10 can all receive the driving signals.

Specifically, taking the projection overlap of the driving signal line 230 and the driving circuit 200 in the light emitting direction of the display panel as shown in fig. 6 as an example, since the same driving signal line 230 is electrically connected with the same transistor in different driving units and the area of the first driving unit 211 is smaller than the area of the second driving unit 221, the straight line where the first signal line sub-section 231 is located in the straight line where the second signal line sub-section 232 is located is staggered in the second direction, so that the projection length of the third signal line sub-section 233 connecting the first signal line sub-section 231 and the second signal line sub-section 232 in the second direction Y is larger than zero, and the driving circuits in the areas with different sizes and positions of the display panel 10 can be guaranteed to receive the driving signals. It is to be noted that the same transistor mentioned above refers to two transistors having the same function in different driving units, e.g. an output transistor in a driving unit.
