[0080] Figure 4 FIG. 1 is a schematic diagram of a partial structure of the first frame region of a display substrate according to an embodiment of the present disclosure. Figure 4 As shown, the display substrate may further include at least one first connection line 12, at least a portion of which is located in the first border area B1. The first connection line 12 may include a first end and a second end that are oppositely disposed. The first end may be connected to a first power line 10, and the second end may be located on a side of the first end opposite to the second direction Y. For example, the display substrate may include multiple first connection lines 12, and the multiple first connection lines 12 may be arranged in pairs with the multiple first power lines 10.
[0081] like Figure 4 As shown, the first connecting line 12 may include a plurality of lines connected in sequence, and the plurality of lines may include a first line 12-1, a second line 12-2, and a third line 12-3. The first line 12-1 and the third line 12-3 may extend along the second direction Y, and the second line 12-2 may extend along the first direction X. The second line 12-2 and the third line 12-3 may both be located in the first frame area B1, a portion of the first line 12-1 is located in the first frame area B1, and the remaining portion of the first line 12-1 is located in the display area AA. Each line has a first end and a second end that are arranged opposite to each other. The first end of the first line 12-1 is connected to the first power line 10, and the second end of the first line 12-1 is located on a side opposite to the first end of the first line 12-1 along the second direction Y. The second end of the first line 12-1 is connected to the first end of the second line 12-2, and the second end of the second line 12-2 is located on a side opposite to the first end of the second line 12-2 along the first direction X. The first end of the third trace 12 - 3 is connected to the second end of the second trace 12 - 2 , and the second end of the third trace 12 - 3 is located on a side opposite to the first end of the third trace 12 - 3 along the second direction Y.
[0082] like Figure 4 As shown, along a direction perpendicular to the plane of the substrate, the first border area B1 of the display substrate may include a first conductive layer and a second conductive layer stacked together, and the first conductive layer is closer to the substrate than the second conductive layer. For example, the first conductive layer may be arranged in the same layer as the first source and drain metal layer, and the second conductive layer may be arranged in the same layer as the second source and drain metal layer. The first power line 10 may be located in the first conductive layer, and the first data signal line DL-1 and the second data signal line DL-2 may be located in the second conductive layer. The first power line 10 and the first data signal line DL-1 and the second data signal line DL-2 are arranged in layers to avoid problems such as short circuits between signals caused by overly dense signal line layout. The first trace 12-1 extends along the second direction Y and is located between adjacent first data signal lines DL-1 and second data signal lines DL-2. The orthographic projections of the first trace 12-1 and the second power bus 21 on the substrate plane at least partially overlap. The second power bus 21 is located in the first conductive layer, while the first trace 12-1 is located in the second conductive layer. By arranging the second power bus 21 and the first trace 12-1 on different conductive layers, a short circuit between the second power bus 21 and the first trace 12-1 can be avoided. The second trace 12-2 extends along the first direction X, and the orthographic projections of the second trace 12-2 on the substrate plane partially overlap with at least one data signal line. The second trace 12-2 is located in the first conductive layer, while the data signal line is located in the second conductive layer. This prevents a short circuit between the second trace 12-2 and the data signal line.
[0083] The display substrate may further include a plurality of multiplexing control lines, which may include at least a first multiplexing control line MUX1, a second multiplexing control line MUX2, a third multiplexing control line MUX3, and a fourth multiplexing control line MUX4. The third routing line 12-3 overlaps with the orthographic projection of at least one of the multiplexing control lines on the plane where the substrate is located. The third routing line 12-3 is located in the second conductive layer, and the multiplexing control lines are located in the first conductive layer. This arrangement can avoid signal coupling between the third routing line 12-3 and the multiplexing control lines, thereby improving the display quality of the display device. For example, the third routing line 12-3 overlaps with the orthographic projections of the first multiplexing control line MUX1, the second multiplexing control line MUX2, the third multiplexing control line MUX3, and the fourth multiplexing control line MUX4 on the plane where the substrate is located.
[0084] like Figure 4As shown, the display substrate may further include at least one second power bus branch line 21-1. The second power bus branch line 21-1 may be located in the first border region B1 and located in the first conductive layer. The second power bus branch line 21-1 may extend along a second direction Y. The second power bus branch line 21-1 may include a first end and a second end disposed opposite each other. The first end may be connected to the second power bus 21, and the second end may be located on a side opposite to the second direction Y of the first end.
[0085] like Figure 4 As shown, at least a portion of the second trace 12-2 is located between the multiplexing circuit 22 and the display area AA. For example, the entire second trace 12-2 is located between the multiplexing circuit 22 and the display area AA. At least a portion of the third trace 12-3 is located on one side of the multiplexing circuit 22 along the first direction X. For example, at least a portion of the third trace 12-3 is located on a side of the multiplexing circuit 22 opposite to the first direction X.
[0086] The multiplexing circuit 22 may include at least a plurality of multiplexing control transistors 22-1. For example, the multiplexing circuit 22 may include four multiplexing control transistors 22-1, and the four multiplexing control transistors 22-1 may be arranged sequentially along the first direction X. The multiplexing control transistor 22-1 may include at least a gate, a source, and a drain. The gate (not shown) of the multiplexing control transistor 22-1 may be connected to the multiplexing control line, one of the source and the drain of the multiplexing control transistor 22-1 may be connected to the data signal line, and the other of the source and the drain of the multiplexing control transistor 22-1 may be connected to the data transmission line 30. For example, the four multiplexing control transistors 22-1 may be connected to the same data transmission line 30.
[0087] The orthographic projection of the third trace 12 - 3 on the plane where the substrate is located can be located between the orthographic projection of the second power bus branch line 21 - 1 and the multiplexing circuit 22 on the plane where the substrate is located, thereby avoiding crosstalk between different signals.

As shown, Figure 5A As shown, the fourth wire 13-4 and the sixth wire 13-6 can be located in the second conductive layer, and the fifth wire 13-5 can be located in the first conductive layer. In the embodiments of the present disclosure, by arranging the second connection line, the low-voltage signals of the sub-pixels close to the first transition area and the sub-pixels close to the first frame area can be kept substantially consistent, which is beneficial to ensuring the uniformity of display.

The fourth trace 13-4 can be located in the second conductive layer, and the second power transmission line 21-2 can be located in the first conductive layer. By arranging the fourth trace 13-4 and the second power transmission line 21-2 in different conductive layers, signal crosstalk between the fourth trace 13-4 and the second power transmission line 21-2 can be avoided.

[0100] Figure 5B A partial structure schematic view of a first transition region of a display substrate of another embodiment of the present disclosure is shown in FIG. 6. As shown in FIG. 6, because the number of sub-pixels included in the sub-pixel columns close to the first transition region G1 in the display region AA are not all the same, for example, the number of sub-pixels included in the sub-pixel columns close to the first transition region G1 are all different, as shown in FIG. 6, the second connection line 13 can be bent at a position close to each sub-pixel column, that is, at least a portion of the second connection line 13 close to the side of the display region AA can be a step shape in the orthographic projection of the plane where the substrate is located, which can reduce the space occupied by the display substrate and achieve a narrow frame of the display device.

The display device can have a display side and a non-display side. The display side can be a side on which the display device can display an image. When the human eye is on the display side, the image displayed by the display device can be viewed. The non-display side is opposite the display side. The sensor can be disposed on the non-display side of the display device, and thus the sensor can be referred to as an under-screen sensor. Since the sensor needs to receive light signals transmitted through the display device from the outside, the display device needs to have a higher light transmittance in the area corresponding to the sensor.
[0108] As shown in Figure 8 The display substrate can include a substrate, a display region AA on the substrate, and a peripheral region BB on the substrate and surrounding the display region AA. The display region AA can include a first region AA1 and a second region AA2 that do not overlap each other. The first region AA1 can be referred to as a sensor non-corresponding area, and the second region AA2 can be referred to as a sensor corresponding area. The light transmittance of the second region AA2 is higher than that of the first region AA1. The orthographic projection of the sensor on the display substrate can at least partially overlap the second region AA2, so that more light can pass through the display substrate and be received by the sensor. For example, a part of the orthographic projection of the sensor on the display substrate is located within the second region AA2. Alternatively, the entire orthographic projection of the sensor on the display substrate is located within the second region AA2. The first region AA1 can be a region of the display region AA other than the second region AA2.

The first power transmission line 18 can be connected with the plurality of first power lines 10, which can improve the uniformity of the display area as a whole and avoid display dark areas. Figure 8 In some example embodiments, as shown in FIG. 1, the display substrate can further include a first power transmission line 18 configured to transmit a low-voltage signal. The first power transmission line 18 is located in the first area AA1 and surrounds at least part of the second area AA2. For example, the first power transmission line 18 can surround the entire second area AA2. The first power transmission line 18 can be connected with the plurality of first power lines 10, which can improve the uniformity of the display area as a whole and avoid display dark areas.
