Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] The under-screen camera technology is to set a light-transmitting area on the display panel, and set the camera opposite to the light-transmitting area to achieve full-screen display. In the related art, in order to improve the transmittance of the light-transmitting area, usually only a light-emitting unit is set in the light-transmitting area, and a transition display area is set on both sides of the row direction of the light-transmitting area, and a pixel driving circuit for driving the light-emitting unit is set in the transition display area. The data line located in the same sub-pixel column as the light-emitting unit in the light-transmitting area needs to be connected to the pixel driving circuit located in the transition display area by winding. However, when the light-transmitting area is surrounded by the main display area, the main display area is also set on both sides of the transition display area in the column direction, and the data line in the main display area on one side of the transition display area needs to pass through the transition display area to extend to the main display area on the other side of the transition display area. However, the data line running through the transition display area is prone to crosstalk with the data line connected to the transition display area by winding.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0049] like Figure 1 , 2 As shown, Figure 1 is a structural schematic diagram of a display panel in the related art, Figure 2 for Figure 1 The enlarged view of the dotted box A in the figure. Figure 1 , 2 As shown, the display panel includes a main display area 01, a light-transmitting area 03, and a transitional display area 02. Figure 2 As shown, only the light-emitting unit A is arranged in the light-transmitting area 03 of the display panel, and the sub-pixel P with the light-emitting unit and the pixel driving circuit D without the light-emitting unit are arranged in the transition display area 02 of the display panel. The display panel can provide a driving current to the light-emitting unit A located in the light-transmitting area 03 through the pixel driving circuit D located in the transition display area 02. Since the pixel driving circuit is not arranged in the light-transmitting area 03, the light-transmitting area has a high light transmittance. Figure 2 As shown, in order to achieve normal driving, the data line d8 located in the same sub-pixel column as the light-emitting unit A needs to be connected to the pixel driving circuit D that provides driving current to the light-emitting unit A. In the related art, the method of connecting the data line d8 to the pixel driving circuit D in the transition display area 02 can be as follows Figure 2 As shown, the data line d8 bypasses the collection area B, and is connected to the data line d7 in the transition display area 02 through the gate line g in the edge routing area, wherein the data line d7 is connected to the pixel driving circuit D in the transition display area 02. When the side of the transition display area 02 away from the main display area 01 also needs to be set with a main display area, such as Figure 2As shown, the data line d2 located in the main display area 01 needs to pass through the transition display area 02 to connect to the main display area on the other side of the transition display area 02. However, the data line d7 and part of the data line d2 are located in the same sub-pixel column, and the data line d7 and the data line d2 located in the same sub-pixel column are prone to signal crosstalk.

[0050] Based on this, the present exemplary embodiment provides a display panel such as Figure 3 The figure is a schematic diagram of the structure of an exemplary embodiment of the display panel of the present disclosure. The display panel may include a light-transmitting area 1, a first transitional display area 2, a first wiring area 3, a first main display area 41, and a second main display area 42; the first transitional display area 2 is located on both sides of the light-transmitting area 1 in the row direction Y, and the first wiring area 3 is located on the side of the first transitional display area 2 away from the light-transmitting area 1; the first main display area 41 is located on one side of the light-transmitting area 1, the first transitional display area 2, and the first wiring area 3 in the column direction X, and the second main display area 42 is located on the other side of the light-transmitting area 1, the first transitional display area 2, and the first wiring area 3 in the column direction X. The display panel also includes: a first light-emitting unit A1, a first pixel driving circuit D1, a first signal line d1, a second signal line d2, and a third signal line g3. The first light-emitting unit A1 may be located in the light-transmitting area 1; the first pixel driving circuit D1 may be located in the first transitional display area 2, and the first pixel driving circuit D1 may be used to provide a driving current to the first light-emitting unit A1. The first signal line d1 may extend along the column direction X, and at least a portion of the first signal line d1 is located in the first main display area 41, and is used to provide a driving signal to a pixel driving circuit located in the same sub-pixel column as the first pixel driving circuit D1; the second signal line d2 may extend along the column direction X, and at least a portion of the second signal line d2 is located in the second main display area 42, and is used to provide a driving signal to a pixel driving circuit located in the same sub-pixel column as the first pixel driving circuit D1; at least a portion of the third signal line g3 may be located in the first routing area 3, and the third signal line d3 may be connected to the first signal line d1 and the second signal line d2 through the via 81, respectively. The first signal line d1 and the second signal line d2 may be data signal lines. The third signal line g3 may be located in a different conductive layer from the first signal line d1, and the third signal line g3 may be located in a different conductive layer from the second signal line d2.

[0051] This exemplary embodiment connects the first signal line d1 and the second signal line d2 via the third signal line g3 located in the first wiring area 3, thereby avoiding the appearance of two data lines in the sub-pixel column where the first pixel driving circuit D1 is located in the first transition display area 2, thereby avoiding signal crosstalk between the two data lines with a close spacing.

[0052] It should be noted that, in this exemplary embodiment, the description of “the first area is located on one side of the second area in the column direction” can be understood as the area through which the first area moves in the column direction covers the second area.

[0053] In this exemplary embodiment, Figure 3 As shown, the display panel may further include a signal line d7 and a signal line d8, wherein at least a portion of the signal line d7 may be located in the first transition display area 2, and the signal line d7 may be used to connect to the first pixel driving circuit D1, and at least a portion of the signal line d8 may be located in the second main display area 42, and the signal line d8 may be used to provide a driving signal (e.g., a data signal) to a sub-pixel unit located in the same sub-pixel column as the first light-emitting unit A1.

Figure 2 The signal line d7 and the signal line d8 have the same connection structure, and the signal line d7 and the signal line d8 in this exemplary embodiment can be connected through a gate line g. The gate line g can be located between the first main display area 41 and the light-transmitting area 1. The gate line g can be located in a different conductive layer from the signal line d7, and the gate line g can be located in a different conductive layer from the signal line d8.

[0054] like Figure 4 FIG. 2 is a schematic diagram of another exemplary embodiment of the display panel of the present disclosure. In this exemplary embodiment, the gate line g can also be formed in the first transition display area 2, and at least part of the sub-pixel rows in the first transition display area 2 can be correspondingly provided with a gate line g.

[0055] In this exemplary embodiment, the third signal line g3 may also be located in other areas. Figure 5 FIG. 2 is a schematic diagram of the structure of another exemplary embodiment of the display panel of the present disclosure. In this exemplary embodiment, the display panel may not be provided with a first routing area, and at least a portion of the third signal line g3 may be located in the first transition display area 2. The signal line d7 may be located in the same conductive layer as the first signal line d1 and the second signal line d2. At the same time, since the third signal line g3 and the first signal line d1 are located in different conductive layers, and the third signal line g3 and the second signal line d2 are located in different conductive layers, the third signal line g3 and the signal line d7 are located in different conductive layers, so that this setting can also reduce the signal crosstalk between the third signal line g3 and the signal line d7.

[0056] like Figure 6, which is a schematic diagram of the structure of another exemplary embodiment of the display panel of the present disclosure. The display panel may further include: a second light-emitting unit A2, a second pixel driving circuit D2, a fourth signal line d4, a fifth signal line d5, and a sixth signal line g6.

The fourth signal line d4 may extend along the column direction X, and at least a portion of the fourth signal line d4 may be located in the first main display area 41, and may be used to provide a driving signal to a pixel driving circuit located in the same sub-pixel column as the second pixel driving circuit D2; the fifth signal line d5 may extend along the column direction, and at least a portion of the fifth signal line d5 may be located in the second main display area 42, and may be used to provide a driving signal to a pixel driving circuit located in the same sub-pixel column as the second pixel driving circuit D2; at least a portion of the sixth signal line g6 may be located in the first wiring area 3, and the sixth signal line g6 may be connected to the fourth signal line d4 and the fifth signal line d5 through vias, respectively. The fourth signal line d4 and the fifth signal line d5 may be data lines, the sixth signal line g6 may be located in a different conductive layer from the fourth signal line d4, the sixth signal line g6 may be located in a different conductive layer from the fifth signal line d5, and the fourth signal line d4 and the fifth signal line d5 may be located in the same conductive layer. It should be understood that in other exemplary embodiments, the sixth signal line g6 may also be located in the first transition display area 2, and the sixth signal line g6 may extend along the column direction X to directly connect the fourth signal line d4 and the fifth signal line d5.

[0057] In this exemplary embodiment, only the second light-emitting unit may be arranged in the first wiring area, and no pixel driving circuit may be arranged, and the display panel drives the second light-emitting unit A2 through the second pixel driving circuit D2 located in the first transition display area 2. The display panel can ensure that the first wiring area 3 emits light normally without affecting the normal routing of the third signal line g3 and the sixth signal line g6 in the first wiring area 3.

[0058] In this exemplary embodiment, Figure 6As shown, the first transition display area 2 may include a first sub-transition display area 201 and a second sub-transition display area 202, and the second sub-transition display area 202 may be located between the first sub-transition display area 201 and the first wiring area 3; the first pixel driving circuit D1 may be located in the first sub-transition display area 201, and the second pixel driving circuit D2 may be located in the second sub-transition display area 202. This arrangement allows the first light-emitting unit A1 to be connected to the pixel driving circuit in the first sub-transition display area 201 that is closer to it, thereby reducing the voltage drop caused by the resistance of the conductive line between the first light-emitting unit A1 and the first pixel driving circuit D1, and at the same time, this arrangement allows the second light-emitting unit A2 to be connected to the pixel driving circuit in the second sub-transition display area 202 that is closer to it, thereby reducing the voltage drop caused by the resistance of the conductive line between the second light-emitting unit A2 and the second pixel driving circuit D2.

[0059] In this exemplary embodiment, Figure 3-6 As shown, the display panel may further include a third sub-pixel P3, the third sub-pixel P3 may be located in the first transition display area 2, the third sub-pixel P3 may include a third light-emitting unit and a third pixel driving circuit, and the third pixel driving circuit may be used to provide a driving current to the third light-emitting unit.

The third sub-pixel may be located in a different sub-pixel column from the first pixel driving circuit and the second pixel driving circuit. This setting may enable the data line d6 used to connect the third sub-pixel P3 to be located in a different sub-pixel column from the data line used to connect the first pixel driving circuit D1 and the data line used to connect the second pixel driving circuit D2, thereby avoiding multiple data lines being located in the same sub-pixel column.

[0060] In this exemplary embodiment, Figure 3-6As shown, both the first light-emitting unit A1 and the first pixel driving circuit D1 can be multiple, the first pixel driving circuit D1 and the first light-emitting unit A1 connected thereto can be located in the same row, and each of the first pixel driving circuits D1 can be spaced apart from the first light-emitting unit A1 connected thereto by the same sub-pixel column in the row direction. That is, each of the first pixel driving circuits D1 and the first light-emitting unit A1 connected thereto can be spaced apart by the same distance in the row direction. This arrangement can make the second connecting wires 72 used to connect the first pixel driving circuit D1 and the first light-emitting unit A1 have the same length, that is, each connecting wire has the same voltage drop under the same voltage, so that the display panel can have better display uniformity.
