Description

[Technical Field]

[0001] This invention relates to the field of display technology, and more particularly to a display panel and display device. [Background Technology]

[0002] For display panels with camera functions, in order to increase the screen-to-body ratio, the component setting area for the corresponding camera is usually set inside the display area. This component setting area is used for both display and light transmission, so that ambient light can enter the camera.

[0003] However, the display performance and light transmission performance of the component setting area are mutually restrictive: if you want to increase the pixel density of the component setting area to improve its display performance, it will lead to a decrease in the light transmission of the component setting area. On the other hand, if you want to optimize the light transmission performance of the component setting area, you cannot set too many pixels in the component setting area, which will result in a poor display effect. [Summary of the Invention]

[0004] In view of this, embodiments of the present invention provide a display panel and a display device to enable the component mounting area to achieve both good display performance and light transmission performance.

[0005] On one hand, embodiments of the present invention provide a display panel, including:

[0006] A display area and a border area surrounding the display area, the display area including a main display area and a component setting area;

[0007] A shift register circuit located in the border area, the shift register circuit including a first shift register circuit, the first shift register circuit being close to the display area;

[0008] The first light-emitting unit located in the component setting area;

[0009] The first pixel circuit is located in the border area, the first pixel circuit is electrically connected to the first light-emitting unit, and at least a portion of the first pixel circuit is located on one side of the first shift register circuit.

[0010] On the other hand, embodiments of the present invention provide a display device including the above-described display panel.

[0011] One of the above technical solutions has the following beneficial effects:

[0012] In this embodiment of the invention, when designing the first pixel circuit electrically connected to the first light-emitting unit in the component setting area, it is not placed in the component setting area, but rather moved to the border area and positioned on the side closer to the first shift register circuit in the display area. This releases a portion of the light-transmitting area in the component setting area, which can be used to further improve the light transmittance of the component setting area and / or further increase the number of the first light-emitting units in the component setting area, so that the component setting area has both good light transmittance and display performance. For example, while ensuring a high light transmittance in the component setting area, the number of the first light-emitting units in the component setting area can be increased, making the density of its light-emitting units more consistent with the density of the light-emitting units in the main display area, thus weakening the display difference between the component setting area and the main display area.

[0013] Moreover, when the first pixel circuit is located on the side of the first shift register circuit, the first pixel circuit is closer to the display area, which can reduce the connection distance between the first pixel circuit and the first light-emitting unit, thereby reducing the attenuation of the driving signal provided by the first pixel circuit during transmission and further optimizing the display effect of the component setting area.

Detailed Implementation Methods

[0029] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0033] This invention provides a display panel, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention. The display panel includes a display area DA and a border area BA surrounding the display area DA. The display area DA includes a main display area MDA and a component placement area CA. The component placement area CA is a light-transmitting display area for corresponding optical components such as cameras. Ambient light passes through the component placement area CA and enters the camera so that the camera can collect the ambient light. In this embodiment of the present invention, the display area DA may include one or more component placement areas CA, and the component placement area CA can be any shape such as square, circular, or elliptical.

[0034] The display panel also includes a shift register circuit 1, located in the bezel area BA, which provides corresponding signals to the scan signal lines and light emission control signal lines in the display area DA. The shift register circuit 1 includes a first shift register circuit 4, which is located near the display area DA.

[0035] The display panel also includes a first light-emitting unit 2 and a first pixel circuit 3 electrically connected to the first light-emitting unit 2. The first light-emitting unit 2 is located in the component setting area CA, and can be an organic light-emitting diode (OLED) or a light-emitting diode (LED). The first pixel circuit 3 is located in the bezel area BA, and at least a portion of the first pixel circuit 3 is located on one side of the first shift register circuit 4.

[0036] In this embodiment of the invention, when designing the first pixel circuit 3, which is electrically connected to the first light-emitting unit 2 in the component setting area CA, it is not placed in the component setting area CA, but rather moved to the border area BA and positioned on the side close to the first shift register circuit 4 in the display area DA. This releases a portion of the light-transmitting area in the component setting area CA, which can be used to further improve the light transmittance of the component setting area CA and / or further increase the number of the first light-emitting units 2 in the component setting area CA, so that the component setting area CA has both good light transmittance and display performance. For example, while ensuring that the component setting area CA has high light transmittance, the number of the first light-emitting units 2 in the component setting area CA can be increased, making the density of its light-emitting units more consistent with the density of the light-emitting units in the main display area MDA, thus weakening the display difference between the component setting area CA and the main display area MDA.

[0037] Moreover, when the first pixel circuit 3 is located on one side of the first shift register circuit 4, the first pixel circuit 3 is closer to the display area DA, so the connection distance between the first pixel circuit 3 and the first light-emitting unit 2 can be reduced, thereby reducing the attenuation of the driving signal provided by the first pixel circuit 3 during transmission and further optimizing the display effect of the component setting area CA.

[0038] In one feasible implementation, see Figures 2-5 The first shift register circuit 4 includes a plurality of first shift units 5 cascaded together, wherein the plurality of first shift units 5 include a first sub-shift unit 6 and a second sub-shift unit 7, and the area of ​​the first sub-shift unit 6 is smaller than the area of ​​the second sub-shift unit 7.

[0039] In this embodiment of the invention, the area of ​​a portion of the first shift unit 5 in the first shift register circuit 4 is compressed to release some space near the first shift register circuit 4. In this way, the first pixel circuit 3 can be directly placed in this space. On the one hand, this avoids the need to increase the width of the border area BA to accommodate the first pixel circuit 3. On the other hand, when the purpose of placing the first pixel circuit 3 on one side of the first shift register circuit 4 is achieved, there is no need to change the layout design of other shift register circuits 1, and the impact on the layout design of the circuit in the border area BA is small.

[0040] Furthermore, it is understandable that the area of ​​the component setting area CA is usually much smaller than the area of ​​the main display area MDA, and therefore the number of first light-emitting units 2 set inside it is less, and correspondingly, the number of first pixel circuits 3 connected to it is also less. Therefore, in the above setting method, only the area of ​​some of the first shifting units 5 needs to be compressed to free up enough space to accommodate the first pixel circuits 3, while the other first shifting units 5 can retain their original design, and the overall impact on the first shift register circuit 4 is small.

[0041] In one feasible implementation, such as Figures 2-4 As shown, Figure 2 This is a partial structural diagram of a display panel provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of another partial structure of the display panel provided in an embodiment of the present invention. Figure 4 This is a partial structural diagram of a display panel provided in an embodiment of the present invention. At least a portion of the first sub-shifting unit 6 has a smaller dimension in the second direction y than the second sub-shifting unit 7 in the second direction y. The second direction y intersects the arrangement direction of the first shift register circuit 4 and the display area DA. At least a portion of the first pixel circuit 3 is located on one side of the first shift circuit in the second direction y.

[0042] In the above configuration, by compressing at least part of the size of the first sub-shift unit 6 in the second direction y, the size of the entire first shift register circuit 4 in the second direction y can be reduced. For example, in the conventional structure, the size of the shift register circuit 1 in the second direction y is equal to the size of the display area DA in the second direction y. After the above adjustment, the size of the first shift register circuit 4 in the second direction y can be compressed to be smaller than the size of the display area DA in the second direction y. This frees up some space on one side of the first shift register circuit 4 in the second direction y to accommodate the first pixel circuit 3.

[0043] It should be noted that in the above configuration, the first sub-shift unit 6 compressed in the second direction y can be any number of first shift units 5 in the first shift register circuit 4, and these first sub-shift units 6 can be arranged continuously or discontinuously. It is understood that regardless of which number of first shift units 5 are compressed in the second direction y, the purpose of compressing the size of the entire first shift register circuit 4 in the second direction y can be achieved. In one configuration shown in the embodiment of the present invention, the first sub-shift units 6 are arranged continuously, and the second sub-shift units 7 are arranged continuously.

[0044] In one feasible implementation, see Figures 3-5 , Figure 5 This is a partial structural diagram of a display panel provided in an embodiment of the present invention. The first sub-shifting unit 6 includes a first type of first sub-shifting unit 8. The size of the first type of first sub-shifting unit 8 in the first direction x is smaller than the size of the second sub-shifting unit 7 in the first direction x. The first direction x is the arrangement direction of the first shift register circuit 4 and the display area DA. At least a portion of the first pixel circuit 3 is located on the side of the first type of first sub-shifting unit 8 closest to the display area DA.

[0045] In the above configuration, by compressing the size of the first type of first sub-shifting unit 8 in the first direction x, a portion of space can be freed up on the side of the first type of first sub-shifting unit 8 near the display area DA to accommodate the first pixel circuit 3, thereby bringing the first pixel circuit 3 closer to the display area DA and reducing the connection distance between the first pixel circuit 3 and the first light-emitting unit 2 to a greater extent.

[0046] It should be noted that, in the embodiments of the present invention, the first shift register circuit 4 may include at least one of the following three types of first sub-shift units 6: First type of first sub-shift unit 6: compression is performed only in the first direction x, while the size remains unchanged or increases in the second direction y; Second type of first sub-shift unit 6: compression is performed only in the second direction y, while the size remains unchanged or increases in the first direction x; Third type of first sub-shift unit 6: compression is performed in both the first direction x and the second direction y.

[0047] For example, see Figure 2 The first shift register circuit 4 includes only the first sub-shift unit 6 that is compressed in the second direction y. In this case, in one configuration, all the first pixel circuits 3 are located on one side of the first shift register circuit 4 in the second direction y.

[0048] Or see Figure 5 The first shift register circuit 4 includes only the first sub-shift unit 6 that is compressed in the first direction x. In this case, in one configuration, all the first pixel circuits 3 can be located on the side of this part of the first sub-shift unit 6 that is close to the display area DA.

[0049] Or see Figure 3 The first shift register circuit 4 includes a first sub-shift unit 6 compressed in the second direction x, and also includes a first sub-shift unit 6 compressed in both the first direction x and the second direction y. In one configuration, a portion of the first pixel circuit 3 is located on one side of the first shift register circuit 4 in the second direction y, and a portion of the first pixel circuit 3 is located on the side of the first sub-shift unit 6 compressed in both the first direction x and the second direction y that is closer to the display area DA.

[0050] Or see Figure 4 The first shift register circuit 4 includes a first sub-shift unit 6 that is compressed only in the second direction x, and also includes a first sub-shift unit 6 that is compressed only in the first direction x. In this case, in one configuration, a portion of the first pixel circuit 3 is located on one side of the first shift register circuit 4 in the second direction y, and a portion of the first pixel circuit 3 is located on the side of the first sub-shift unit 6 that is compressed in the first direction x that is close to the display area DA.

[0051] In one feasible implementation, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the size of a transistor in the first shift unit 5 provided in an embodiment of the present invention. The first sub-shift unit 6 includes a plurality of first transistors M1, and the second sub-shift unit 7 includes a plurality of second transistors M2. At least some of the first transistors M1 are smaller than the size of the second transistors M2 that have the same connection relationship with them.

[0052] It should be noted that the circuit structures of each first shift unit 5 in the first shift register circuit 4 are identical. Therefore, each first transistor M1 in the first sub-shift unit 6 can find a second transistor M2 with the same connection relationship in the second sub-shift unit 7. For clarity, Figure 6 The first transistor M1 and the second transistor M2, which have the same connection relationship, are represented by reference numerals M1_i and M2_i, respectively.

[0053] In this configuration, by compressing the size of the first transistor M1 in the first sub-shift unit 6, the size of the first sub-shift unit 6 in the first direction x and / or the second direction y can be compressed, thereby freeing up some space on one side of the first shift register circuit 4 to accommodate the first pixel circuit 3.

[0054] In addition, it should be noted that, Figure 6 The diagram is merely a simplified illustration of the size comparison of transistors in different first shift units 5. The number of transistors and their connections are not intended to limit the number of transistors or their connections in the first shift unit 5. In this embodiment of the invention, the first shift unit 5 can employ various circuit structures.

[0055] In one feasible implementation, such as Figure 7 As shown, Figure 7 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The size of the first shift register circuit 4 in the second direction y is smaller than the size of the display area DA in the second direction y. Furthermore, the first shift register circuit 4 includes a plurality of cascaded first shift units 5, the plurality of first shift units 5 having equal size in the second direction y, and the second direction y intersects the arrangement direction of the first shift register circuit 4 and the display area DA. At least a portion of the first pixel circuits 3 are located on one side of the first shift register circuit 4 in the second direction y.

[0056] In the traditional structure, the size of the shift register circuit 1 in the second direction y is equal to the size of the display area DA in the second direction y. In the above configuration, the size of each first shift unit 5 in the first shift register circuit 4 in the second direction y is reduced to the same degree. For example, the size of each stage of the first shift unit 5 in the second direction y is reduced from 75μm to 70μm, thereby reducing the overall size of the first shift register circuit 4 in the second direction y. With this configuration, the areas of the different first shift units 5 in the first shift register circuit 4 are the same. Therefore, the size of the transistors in the different first shift units 5 can be set to be the same, making the device characteristics of the transistors in the different first shift units 5 more consistent, and thus the circuit characteristics of the different first shift units 5 more consistent.

[0057] In one feasible implementation, such as Figure 8 As shown, Figure 8This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The size of the first shift register circuit 4 in the second direction y is larger than the size of the display area DA in the second direction y. Furthermore, the first shift register circuit 4 includes a plurality of cascaded first shift units 5, the plurality of first shift units 5 having equal size in the second direction y, which intersects the arrangement direction of the first shift register circuit 4 and the display area DA. At least a portion of the first pixel circuits 3 are located on the side of the first shift register circuit 4 closer to the display area DA.

[0058] In the above configuration, the size of the first shift unit 5 in the first direction x is compressed by elongating it in the second direction y. This configuration results in a smaller adjustment range for the area of ​​a single first shift unit 5, thus reducing the difficulty of layout design for the first shift unit 5. Moreover, with this configuration, the areas of different first shift units 5 in the first shift register circuit 4 are the same. Therefore, the transistors in different first shift units 5 can be made to have the same size, making the device characteristics of the transistors in different first shift units 5 more consistent, and consequently, the circuit characteristics of different first shift units 5 more consistent.

[0059] Of course, in other optional embodiments of the present invention, such as Figure 9 As shown, Figure 9 This is another structural schematic diagram of the display panel provided in the embodiment of the present invention. After the dimensions of the multiple first shift units 5 in the first direction x are compressed, the dimensions of the first shift register circuit 4 in the second direction y can remain unchanged and are still equal to the dimensions of the display area DA in the first direction x. That is, this method only compresses the dimensions of the first shift units 5 in the first direction x, without stretching the dimensions of the first shift units 5 in the second direction y.

[0060] In one feasible implementation, such as Figure 10 As shown, Figure 10 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The shift register circuit 1 further includes a second shift register circuit 9. The second shift register circuit 9 is located on the side of the first shift register circuit 4 away from the display area DA. The size of the second shift register circuit 9 in the second direction y is smaller than the size of the display area DA in the second direction y. Part of the first pixel circuit 3 is located on the side of the second shift register circuit 9 in the second direction y. The second direction y intersects with the arrangement direction of the first shift register circuit 4 and the display area DA.

[0061] The above structure also compresses the size of the second shift register circuit 9 in the second direction y, so that a portion of the first pixel circuit 3 can also be accommodated on one side of the second shift register circuit 9 in the second direction y. Given a fixed number of first pixel circuits 3, the first pixel circuits 3 can be distributed on one side of the first shift register circuit 4 and the second shift register circuit 9. This reduces the compression of the first shift register circuit 4, lowers the layout design difficulty of the first shift register circuit 4, and also avoids overly dense routing of various traces in the first shift register circuit 4, reducing mutual interference between traces.

[0062] In one feasible implementation, see Figure 1 The display area DA includes a first edge 10 and a second edge 11 opposite each other in the second direction y. The second direction y intersects the arrangement direction of the first shift register circuit 4 and the display area DA. The component placement area CA is close to the first edge 10. The distance between the first pixel circuit 3 and the extension line of the first edge 10 is less than the distance between the first pixel circuit 3 and the extension line of the second edge 11, that is, the first pixel circuit 3 is closer to the side of the extension line of the first edge 10. For example, when the component placement area CA is close to the upper edge of the display area DA, the first pixel circuit 3 is also close to the side of the extension line of the upper edge. At this time, the first pixel circuit 3 and the first light-emitting unit 2 are located on the same side of the display panel. This facilitates the wiring design of the connection line between the first pixel circuit 3 and the first light-emitting unit 2, and reduces the extension length of this connection line, thereby reducing the voltage drop generated when the driving signal is transmitted on the connection line.

[0063] In one feasible implementation, such as Figure 11 As shown, Figure 11 This is another schematic diagram of the display panel provided in an embodiment of the present invention. The display area DA includes a third edge 12 and a fourth edge 13 opposite each other in the first direction x. The component setting area CA and the first pixel circuit 3 are both close to the third edge 12. The first direction x is the arrangement direction of the first shift register circuit 4 and the display area DA. For example, when the component setting area CA is close to the left edge of the display area DA, the first pixel circuit 3 is also close to the left edge of the display area DA; or, when the component setting area CA is close to the right edge of the display area DA, the first pixel circuit 3 is also close to the right edge of the display area DA. This arrangement also facilitates the wiring design of the connection line between the first pixel circuit 3 and the first light-emitting unit 2, and reduces the extension length of this connection line.

[0064] In one feasible implementation, such as Figure 12 As shown, Figure 12This is a partial structural diagram of a display panel provided in an embodiment of the present invention. The display area DA includes a first edge 10 and a second edge 11 opposite to each other in the second direction y, and the component setting area CA is close to the first edge 10.

[0065] The display panel includes a plurality of circuit groups 14 arranged along a second direction y on the same side of the display area DA. The circuit group 14 includes at least two first pixel circuits 3 arranged in a first direction x. The first direction x intersects with the second direction y. The first direction x is the arrangement direction of the first shift register circuit 4 and the display area DA.

[0066] In two adjacent circuit groups 14, the circuit group 14 near the extension line of the first edge 10 is the first circuit group 15, and the other circuit group 14 is the second circuit group 16. In some of the two adjacent circuit groups 14, the first light-emitting unit 2 electrically connected to the first circuit group 15 and the second circuit group 16 is arranged along the first direction x. In some of the two adjacent circuit groups 14, the first light-emitting unit 2 electrically connected to the first circuit group 15 is located on the side of the first light-emitting unit 2 electrically connected to the second circuit group 16 that is closer to the first edge 10.

[0067] When there are many first light-emitting units 2 arranged along the first direction x in the component setting area CA, and few first pixel circuits 3 arranged along the first direction x in the border area BA, the above connection method can connect the circuit group 14 to the first light-emitting unit 2 sequentially downwards, and the arrangement of the connection lines between the first light-emitting unit 2 and the first pixel circuit 3 is relatively neat and not too messy.

[0068] In one feasible implementation, such as Figure 13 As shown, Figure 13 This is a partial structural diagram of a display panel provided in an embodiment of the present invention. The display panel includes at least one circuit group 14. The circuit group 14 includes at least two first pixel circuits 3 that are staggered in a first direction x. The first direction x is the arrangement direction of the first shift register circuit 4 and the display area DA.

[0069] It is understandable that the position of the first via 17 in the first pixel circuit 3 for connecting to the first light-emitting unit 2 is fixed. When a circuit group 14 includes multiple first pixel circuits 3, by arranging these multiple first pixel circuits 3 in a staggered manner in the first direction x, the first vias 17 of these multiple first pixel circuits 3 can be staggered with each other in the first direction x. In this way, the connecting line led out from each first pixel circuit 3 can directly extend horizontally along the first direction x to the main display area MDA and then to the first light-emitting unit 2 connected to it. In the border area BA, the connecting line led out from each first pixel circuit 3 does not need to be designed with a bend to avoid the first vias 17 of other first pixel circuits 3. The connection method is simple and the connection distance is short.

[0070] In one feasible implementation, see again Figure 12 The border area BA includes a first sub-border area BA1. The arrangement direction of the first sub-border area BA1 intersects with that of the display area DA and the arrangement direction of the shift register circuit 1 with that of the display area DA. The component setting area CA is close to the first sub-border area BA1.

[0071] At least a portion of the first light-emitting unit 2 is electrically connected to the first pixel circuit 3 via the first connecting line 19, and a portion of the first connecting line 19 is located in the first sub-border area BA1.

[0072] In the above configuration, at least a portion of the connecting line between the first light-emitting unit 2 and the first pixel circuit 3 extends in the first sub-bezel area BA1, thereby reducing the interference between this portion of the connecting line and other signal lines in the display area DA. Moreover, since the component setting area CA is close to the first sub-bezel area BA1, even if this portion of the connecting line extends in the first sub-bezel area BA1, its extension length will not be too large.

[0073] Furthermore, see again Figure 12 The first light-emitting unit 2 includes a first sub-light-emitting unit 20 and a second sub-light-emitting unit 21. The first sub-light-emitting unit 20 is located on the side of the second sub-light-emitting unit 21 closer to the first sub-border area BA1. The first connecting line 19 is electrically connected to the first sub-light-emitting unit 20. That is, the first sub-light-emitting unit 20, which is closer to the first sub-border area BA1, is connected to the first connecting line 19. At this time, when the first connecting line 19 extends towards the first sub-border area BA1 in the component setting area CA, the extension distance is smaller, the degree of occlusion of the component setting area CA is smaller, and the extension distance of the first connecting line 19 is also shorter.

[0074] In one feasible implementation, see again Figure 12 The component setting area CA includes a fifth edge 22 extending along a first direction x, which is the arrangement direction of the first shift register circuit 4 and the display area DA. Multiple first pixel circuits 3 include first sub-pixel circuits 23, which are located on the side of the extension line of the fifth edge 22 facing away from the component setting area CA. The first sub-pixel circuits 23 are electrically connected to the first light-emitting unit 2 via a second connecting line 24. The second connecting line 24 includes a first line segment 25 and a second line segment 26. The second line segment 26 extends from the component setting area CA along a second direction y to the main display area MDA, where the second direction y intersects with the first direction x. The first line segment 25 is connected to the second line segment 26. The first line segment 25 is located on the side of the extension line of the fifth edge 22 facing away from the component setting area CA and extends along the first direction x at least in the main display area MDA.

[0075] Taking the fifth edge 22 as the lower edge of the component setting area CA as an example, when part of the first pixel circuit 3 is located below the extension line of the fifth edge 22, a second line segment 26 can be drawn down from the component setting area CA to extend to the main display area MDA, and then extended to the first pixel circuit 3 via the first line segment 25 extending along the first direction x. In this way, this part of the connecting line is directly drawn from the bottom of the component setting area CA, without occupying all the space on both sides of the component setting area CA in the first direction x. The arrangement of the connecting lines will not be too dense, and the arrangement is also relatively regular.

[0076] It should be noted that, to simplify the process and reduce costs, the first segment 25 can be placed on the same layer as any of the existing scan signal lines, reset signal lines, and light emission control signal lines in the display area DA, while the second segment 26 can be placed on the same layer as the existing data lines and power signal lines in the display area DA. Alternatively, the first segment 25 and the second segment 26 can also be placed on a separate metal layer or a transparent conductive layer, rather than on the same layer as the existing signal lines in the display panel.

[0077] In this embodiment of the invention, the first connecting line 19 and the second connecting line 24 may be formed of a metal material, or, in order to reduce the shading of the component setting area CA, the first connecting line 19 and the second connecting line 24 may also be formed of a light-transmitting conductive material.

[0078] In an embodiment of the present invention, the main display area MDA includes a second light-emitting unit and a second pixel circuit that are electrically connected. At least a portion of the second light-emitting unit and the second pixel circuit that are electrically connected thereto are superimposed, that is, in a direction perpendicular to the plane of the display panel, the orthographic projection of at least a portion of the second light-emitting unit and the orthographic projection of the second pixel circuit that are electrically connected thereto overlap.

[0079] In this embodiment of the invention, the shift register circuit 1 may include at least a scan shift register circuit and an emitter shift register circuit. The scan shift register circuit is electrically connected to the first pixel circuit 3 and the second pixel circuit via a scan signal line, and the emitter shift register circuit is electrically connected to the first pixel circuit 3 and the second pixel circuit via a light emission control signal line. Furthermore, the scan shift register circuit and the emitter shift register circuit can be driven on one side or both sides. The aforementioned first shift register circuit 4 can be either a scan shift register circuit or an emitter shift register circuit, depending on the positional relationship between the scan shift register circuit, the emitter shift register circuit, and the display area DA.

[0080] Furthermore, when the display area DA is provided with shift register circuits 1 on both sides in the first direction x, the first pixel circuits 3 can be distributed on both sides of the display area DA in the first direction x, so as to avoid the excessive number of first pixel circuits 3 arranged on one side and to compress the size of the first shift register circuit 4 on one side to a greater extent.

[0081] Based on the same inventive concept, embodiments of the present invention also provide a display device, such as... Figure 14 As shown, Figure 14 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device includes the aforementioned display panel 100.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
