Fig. 3 is a schematic structural diagram of a flexible display substrate according to an embodiment of the present invention, as shown in fig. 3, the flexible display substrate according to the embodiment of the present invention includes a display area 21 and a peripheral circuit area 22, where the peripheral circuit area 22 includes a bending area 23 located on one side of the display area 21 and a binding area 24 located on one side of the bending area 23 away from the display area 21;
further comprising:
a base substrate 25;
a plurality of signal transmission lines 26 formed on the substrate 25, at least two signal transmission lines 26 are electrically connected to form a signal transmission unit 27 in the bending region 23, each signal transmission unit 27 at least comprises a first signal transmission line 261 and a second signal transmission line 262, a first through hole 263 is formed on the first signal transmission line 261, and a second through hole 264 is formed on the second signal transmission line 262.
In the embodiment of the present invention, as shown in fig. 3, each signal transmission unit 27 at least includes a first signal transmission line 261 and a second signal transmission line 262, and a first through hole 263 is formed on the first signal transmission line 261, and a second through hole 264 is formed on the second signal transmission line 262, and by providing the through holes on the signal transmission line 26, not only can the stress applied to the first signal transmission line 261 and the second signal transmission line 262 during the bending process be reduced, but also the possibility that the first signal transmission line 261 and the second signal transmission line 262 are broken during the bending process is reduced; meanwhile, at least two signal transmission lines 26 are arranged to be electrically connected to form a signal transmission unit 27, so that even if one signal transmission line 26 is broken in the bending process, the whole signal transmission unit 27 can still normally transmit signals, the signals can be ensured to be normally transmitted to the display area 21, and the flexible display substrate can normally display and normally work; moreover, the first signal transmission line 261 and the second signal transmission line 262 are electrically connected to form the signal transmission unit 27, so that the resistance of the whole signal transmission unit 27 can be reduced, the power consumption can be reduced, the signal loss on the signal transmission unit 27 can be reduced, and the display effect of the flexible display panel can be improved. It should be noted that fig. 3 only illustrates that the signal transmission unit 27 includes the first signal transmission line 261 and the second signal transmission line 262, and it is understood that the signal transmission unit 27 provided in the embodiment of the present invention may further include a plurality of signal transmission lines 26, which is not limited in this embodiment of the present invention.
Alternatively, the substrate base 25 may include various suitable materials having flexible or bendable characteristics. For example, the substrate base plate 25 may include a polymer resin such as polyether sulfone (PES), polypropylene resin (PAR), polyether imide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, Polyimide (PI), Polycarbonate (PC), and/or Cellulose Acetate Propionate (CAP).
With reference to fig. 3, in the flexible display substrate according to the embodiment of the present invention, the first signal transmission line 261 is electrically connected to the second signal transmission line 262, and specifically, the first signal transmission line 261 and the second signal transmission line 262 may be electrically connected through a first connection line 281 disposed at two ends of the first signal transmission line 261 and the second signal transmission line 262 and a second connection line 282 disposed between the first signal transmission line 261 and the second signal transmission line 262. As shown in fig. 3, the first signal transmission line 261 and the second signal transmission line 262 are electrically connected through the first connection line 281 and the second connection line 282, so that the connection area between the first signal transmission line 261 and the second signal transmission line 262 can be increased, the resistance of the whole signal transmission unit 27 is further reduced, the loss of the transmission signal on the signal transmission unit 27 is ensured to be small, and the flexible display substrate is ensured to have a good display effect.
Optionally, along the extending direction of the first edge 251 of the substrate base 25, for example, the Y direction shown in the figure, the distance between two adjacent second connecting lines 282 is L1, wherein 10 μm is less than or equal to L1 μm is less than or equal to 200 μm, and further, 20 μm is less than or equal to L1 is less than or equal to 50 μm, the distance L1 between two adjacent second connecting lines 282 is reasonably set, which not only can ensure that the connecting area between the first signal transmission line 261 and the second signal transmission line 262 is increased through the plurality of second connecting lines 282, reduce the resistance of the signal transmission unit 27, ensure that the loss of the transmission signal on the signal transmission unit 27 is small, but also can ensure that the length of L1 matches the length of the signal transmission line 26 in the bending region 23 in the conventional flexible display base.
It should be noted that fig. 3 only illustrates that the distance L1 between two adjacent second connection lines 282 on two signal transmission units 27 is the same, and it is understood that the distance L1 between two adjacent second connection lines 282 on different signal transmission units 27 may be different, or the distance L1 between two adjacent second connection lines 282 at different positions of the same signal transmission unit 27 may be different (not shown in the drawings), the distance L1 between two adjacent second connection lines 282 on different signal transmission units 27 is set to be different, or the distance L1 between two adjacent second connection lines 282 at different positions of the same signal transmission unit 27 is different, the resistances of different signal transmission units 27 may be flexibly adjusted, the resistances of different signal transmission units 27 are ensured to be the same or similar, the signal difference caused by the resistance difference between two adjacent second connection lines 282 on the bending region 23 is reduced, for example, in the signal transmission region 23, when the signal transmission line length of a signal transmission unit 27 is larger, the signal transmission unit 27 may be set to have the same resistance difference between two adjacent second connection lines 27, and thus the signal transmission unit 27 has smaller area, and the signal transmission unit 27 has smaller signal transmission loss, and thus the signal transmission unit 27 area is ensured to be more uniform.
Optionally, with continued reference to fig. 3, along the extending direction of the first edge 251 of the substrate base plate 25, such as the X direction shown in the figure, the extending direction of the first through hole 263 is staggered from the extending direction of the second through hole 264 by a preset distance; meanwhile, the second connection line 282 may include a first end 2821 connected with the first signal transmission line 261 and a second end 2822 connected with the second signal transmission line 262; along the extending direction of the first edge 251 of the substrate base plate 25, the first end 2821 has an overlapping area with the first through hole 263, and the second end 2822 has an overlapping area with the gap between two adjacent second through holes 264; alternatively, in the extending direction of the first edge 251 of the substrate base plate 25, there is an overlapping area between the first end 2821 and the two adjacent first through holes 263, and there is an overlapping area between the second end 2822 and the second through hole 264. Fig. 3 only illustrates that, along the extending direction of the first edge 251 of the substrate base 25, the first end 2821 and the first through hole 263 have an overlapping area, and the second end 2822 and the gap between two adjacent second through holes 264 have an overlapping area.
It is understood that when the flexible display substrate is bent at the bending region 23, the bending trace is generally along the extending direction of the first edge 251 of the substrate base 25, i.e. the X direction in the figure, and the bending trace is shown by the dotted line in the figure. In the embodiment of the present invention, the extending direction of the first through hole 263 and the extending direction of the second through hole 264 are staggered by a predetermined distance along the extending direction of the first edge 251 of the substrate base plate 25, for example, as shown in fig. 3, along the extending direction of the first edge 251 of the substrate base plate 25, there is an overlapping region between the first through hole 263 and two adjacent second through holes 264, and there is an overlapping region between the second through hole 264 and two adjacent first through holes 263; the second connection line 282 connects the first signal transmission line 261 and the second signal transmission line 262, an overlapping region exists between the first end 2821 of the second connection line 282 and the first through hole 263, and an overlapping region exists between the second end 2822 and a gap between two adjacent second through holes 264, so that the bending trace does not completely penetrate through the signal transmission unit 27, the signal transmission unit 27 can still continue to transmit signals, and normal display of the flexible display substrate is ensured. For example, as shown in fig. 3, the bending trace penetrates through the first signal transmission line 261, and the first signal transmission line 261 may be broken, but the bending trace simultaneously corresponds to the second through hole 264 of the second signal transmission line 262, and the second through hole 264 may interrupt the bending trace, so as to ensure that the bending trace cannot penetrate through the second signal transmission line 262, and the signal may be transmitted through the second signal transmission line 262.
Optionally, a plurality of sets of signal transmission units 27 are disposed in the bending region 23, and in each set of signal transmission units 27, the number of the first through holes 263 disposed in the first signal transmission line 261 may be the same or different; similarly, the number of the second vias 264 disposed in the second signal transmission line 262 may be the same or different, which is not limited in the embodiment of the present invention, and fig. 3 only illustrates that the number of the first vias 263 in the two sets of signal transmission units 27 is the same, and the number of the second vias 264 is the same. It can be understood that it is only necessary to ensure that the first through holes 263 are uniformly disposed on the first signal transmission line 261 and the second through holes 264 are uniformly disposed on the second signal transmission line 262, and that the through holes are randomly and uniformly distributed on the signal transmission line 26 along the extending direction of the first edge 251 of the substrate base 25, so as to ensure that the signal transmission units 27 have uniform stress distribution in the extending direction of the first edge 251 of the substrate base 25.
With continued reference to fig. 3, the second connecting line 282 may be a straight line, which ensures simple arrangement and manufacturing method of the second connecting line 282.
Fig. 4 is a schematic structural diagram of another flexible display substrate according to an embodiment of the invention, and as shown in fig. 4, the second connection line 282 may also be a bending line. The first end 2821 of the second connection line 282 is electrically connected to the first signal transmission line 261, and the second end 2822 is electrically connected to the second signal transmission line 262, and fig. 4 illustrates an example where the first end 2821 and the first through hole 263 have an overlapping region, and the second end 2822 and a gap between two adjacent second through holes 264 have an overlapping region. Set up second connecting wire 282 for the bending line, second connecting wire 282 itself does not extend along same direction, when bending district 23 and buckling the flexible display base plate, the extending direction of the first edge 251 of substrate base plate 25 is generally followed to the vestige of buckling, i.e. the X direction in the figure, the vestige of buckling can't run through the first end 2821 and the second end 2822 of second connecting wire 282 simultaneously, guarantee that the first signal transmission line 261 and the second signal transmission line 262 of second connecting wire 282 both sides can not break simultaneously, whole signal transmission unit 27 can not break promptly, guarantee that the signal can normally transmit through signal transmission unit 27, do not influence flexible display base plate and show. Alternatively, the shape of the second connection line 282 may be at least one of a zigzag shape, a U-word line, a V-shape, and a zigzag shape, and fig. 4 illustrates only the shape of the second connection line 282 as a zigzag shape. When the second connecting lines 282 are bending lines, the distance between two adjacent second connecting lines 282 may be the distance between the center lines of two adjacent second connecting lines 282 (not shown in the figure).
Fig. 5 is a schematic structural diagram of another flexible display substrate according to an embodiment of the present invention, as shown in fig. 5, along an extending direction of the first edge 251 of the substrate base 25, such as an X direction shown in the figure, the extending direction of the first through hole 263 is staggered from the extending direction of the second through hole 264 by a predetermined distance; in the extending direction of the first edge 251 of the substrate base 25, the first end 2821 and the first through hole 263 have an overlapping region, and the second end 2822 and the second through hole 264 have an overlapping region.
For example, as shown in fig. 5, an extending direction of the first through hole 263 is staggered from an extending direction of the second through hole 264 by a predetermined distance, for example, an overlapping area exists between the first through hole 263 and a gap between two adjacent second through holes 264 along the extending direction of the first edge 251 of the substrate base plate 25, since a bending trace generally extends along the extending direction of the first edge 251 of the substrate base plate 25, i.e., the X direction in the drawing, the extending direction of the first through hole 263 is staggered from the extending direction of the second through hole 264 by the predetermined distance, the extending direction of the bending trace can be ensured, the first signal transmission line 261 and the second signal transmission line 262 are not broken at the same time, the whole signal transmission unit 27 is ensured not to be broken, the signal transmission unit 27 can still transmit signals, and the normal display of the flexible display base plate is ensured. Meanwhile, along the extending direction of the first edge 251 of the substrate base plate 25, there is an overlapping area between the first end 2821 of the second connecting line 282 and the first through hole 263, and there is an overlapping area between the second end 2822 and the second through hole 264, when the second connecting line 282 is a straight line, because the extending direction of the second connecting line 282 is different from the extending direction of the bending trace, the bending trace cannot simultaneously penetrate through the first end 2821 and the second end 2822 of the second connecting line 282, that is, the bending trace cannot simultaneously penetrate through the first signal transmission line 261 and the second signal transmission line 262, the possibility that the first signal transmission line 261 and the second signal transmission line 262 are simultaneously broken is small, the signal can still be transmitted to the display area 21, and the normal display of the flexible display base plate is ensured; when the second connecting line 282 is a bending line, the second connecting line 282 itself does not extend along the same direction, the bending trace cannot simultaneously penetrate through the first end 2821 and the second end 2822 of the second connecting line 282, it is ensured that the first signal transmission line 261 and the second signal transmission line 262 on both sides of the second connecting line 282 cannot simultaneously break, that is, the whole signal transmission unit 27 cannot break, it is ensured that the signal can be normally transmitted through the signal transmission unit 27, and display is not affected on the flexible display substrate. Fig. 5 illustrates the second connection line 282 as a straight line.
It should be noted that, in the different signal transmission units 27 in fig. 5, the second connection line 282 connects the first through hole 263 and the second through hole 264, which are located closest to each other in the first signal transmission line 261 and the second signal transmission line 262, so that the second connection line 282 has the same extension length in the different signal transmission units 27. It is understood that the extension lengths of the second signal connection lines 282 on different signal transmission units 27 may be different, or the extension lengths of the second signal connection lines 282 at different positions of the same signal transmission unit 27 may be different (not shown in the figure). The extension lengths of the second signal connection lines 282 on different signal transmission units 27 are different, or the extension lengths of the second signal connection lines 282 at different positions of the same signal transmission unit 27 are different, so that the resistances of different signal transmission units 27 can be flexibly adjusted, the resistances of different signal transmission units 27 are the same or similar, the signal difference caused by the resistance difference caused by the different lengths of the signal transmission lines of the signal transmission unit 27 in the bending area 23 is reduced, and the display uniformity of the flexible display substrate is ensured.
Fig. 6 is a schematic structural diagram of another flexible display substrate according to an embodiment of the present invention, as shown in fig. 6, along an extending direction of the first edge 251 of the substrate base 25, as shown in the X direction in the figure, the extending direction of the first through hole 263 is the same as the extending direction of the second through hole 264; meanwhile, in the extending direction of the first edge 254 of the substrate base plate 25, the first end 2821 and the first through hole 263 have an overlapping region, and the second end 2822 and the second through hole 264 have an overlapping region.
Illustratively, when the second connection line 282 is a straight line, since the extending direction of the first through hole 263 is the same as the extending direction of the second through hole 264, the extending direction of the second connection line 282 may be the same as the extending direction of the bending trace, but due to the effects of the first through hole 263 and the second through hole 264, the bending trace may be interrupted by the first through hole 263 and the second through hole 264, the bending trace cannot simultaneously penetrate through the first signal transmission line 261 and the second signal transmission line 262, the possibility that the first signal transmission line 261 and the second signal transmission line 262 are simultaneously broken is low, and the signal can still be transmitted to the display area 21, thereby ensuring normal display of the flexible display substrate. When the second connection line 282 is a bending line, the second connection line 282 itself does not extend along the same direction, and the bending trace cannot simultaneously penetrate through the first end 2821 and the second end 2822 of the second connection line 282, so as to ensure that the bending trace cannot simultaneously penetrate through the first signal transmission line 261 and the second signal transmission line 262; meanwhile, due to the action of the first through hole 263 and the second through hole 264, the bending traces of the first through hole 263 and the second through hole 264 can be interrupted, the first signal transmission line 261 and the second signal transmission line 262 on two sides of the second connection line 282 cannot be broken simultaneously, the whole signal transmission unit 27 cannot be broken, the signals can be normally transmitted through the signal transmission unit 27, and the flexible display substrate is not affected to display. Fig. 6 illustrates the second connection line 282 as a straight line.
Fig. 7 is a schematic structural diagram of another flexible display substrate according to an embodiment of the present invention, as shown in fig. 7, along an extending direction of the first edge 251 of the substrate base 25, as shown in an X direction in the figure, an extending direction of the first through hole 263 is the same as an extending direction of the second through hole 264; meanwhile, in the extending direction of the first edge 254 of the substrate base plate 25, there is an overlapping area between the first end 2821 and the first through hole 263, and there is an overlapping area between the second end 2822 and the gap between two adjacent second through holes 264; alternatively, in the extending direction of the first edge 254 of the substrate base plate 25, there is an overlapping area between the first end 2821 and the two adjacent first through holes 263, and there is an overlapping area between the second end 2822 and the second through hole 264.
Exemplarily, since the extending direction of the first through hole 263 is the same as the extending direction of the second through hole 264 along the extending direction of the first edge 251 of the substrate base plate 25, and the first end 2821 and the first through hole 263 have an overlapping area and the second end 2822 and the two adjacent second through holes 264 have an overlapping area along the extending direction of the first edge 254 of the substrate base plate 25, the second connection line 282 is a bending line, as shown in fig. 7, fig. 7 exemplifies that the first end 2821 and the first through hole 263 have an overlapping area and the second end 2822 and the two adjacent second through holes 264 have an overlapping area. Because the second connection line 282 is a bending line, the second connection line 282 itself does not extend along the same direction, and the bending trace cannot simultaneously penetrate through the first end 2821 and the second end 2822 of the second connection line 282, it is ensured that the bending trace cannot simultaneously penetrate through the first signal transmission line 261 and the second signal transmission line 262; meanwhile, due to the action of the first through hole 263 and the second through hole 264, the bending trace of the first through hole 263 or the second through hole 264 can be interrupted, the first signal transmission line 261 and the second signal transmission line 262 on two sides of the second connection line 282 cannot be broken simultaneously, the whole signal transmission unit 27 cannot be broken, the signal can be normally transmitted through the signal transmission unit 27, and the flexible display substrate is not affected to display.

the shapes of the first boundary line 2611, the second boundary line 2612, the third boundary line 2621, and the fourth boundary line 2622 may be straight lines. Thus, the first signal transmission line 261 and the second signal transmission line 262 are simple in arrangement mode, and the manufacturing method is simple.
