Description

[Technical Field]

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

[0002] Light-emitting diode (LED) display panels are widely used in various display devices due to their advantages such as high brightness, good luminous efficiency, and low power consumption. However, current LED display panels suffer from problems such as difficulties in arranging connecting wires when connecting pixel circuits and light-emitting elements. [Summary of the Invention]

[0003] In view of this, embodiments of the present invention provide a display panel and display device, and a splicing display device, for optimizing the arrangement of connection lines between pixel circuits and light-emitting elements.

[0004] On one hand, embodiments of the present invention provide a display panel including a plurality of pixels, each pixel including a plurality of sub-pixels, each sub-pixel including an electrically connected pixel circuit and a light-emitting element;

[0005] In the pixel, the light-emitting elements of the plurality of sub-pixels are arranged along a first direction, and the pixel circuits of the plurality of sub-pixels are arranged along the first direction;

[0006] In at least one of the pixels, the arrangement order of the plurality of light-emitting elements is different from the arrangement order of the plurality of pixel circuits;

[0007] Alternatively, the arrangement order of multiple pixel circuits in at least two of the pixels is different;

[0008] Alternatively, the arrangement order of multiple light-emitting elements in at least two of the pixels may be different.

[0009] On the other hand, embodiments of the present invention provide a display device including the above-described display panel.

[0010] In another aspect, embodiments of the present invention provide a splicing display device, including the aforementioned display panel.

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

[0012] In this embodiment of the invention, the arrangement order of pixel circuits and / or light-emitting elements in at least a portion of pixels is adjusted. This adjustment can be specifically applied to pixels where the pixel circuits and light-emitting elements need to be connected by a first connecting portion, thereby making the arrangement design of the first connecting portion more flexible. For example, when the pixel circuits and light-emitting elements in a portion of pixels are far apart, compared to the conventional arrangement of pixel circuits and light-emitting elements in related technologies, this embodiment of the invention, after changing the arrangement order of the pixel circuits and / or light-emitting elements, allows the multiple first connecting portions corresponding to that pixel to avoid each other without the need for winding, thus preventing overlap.

[0013] Therefore, by adopting the technical solution provided by the embodiments of the present invention, the wiring of the first connection part corresponding to the pixel can be optimized: under the premise of avoiding the first connection part winding as much as possible, more first connection parts can adopt a single-layer design. On the one hand, it can simplify the design of the film layer of the first connection part itself, without the need to set up a bridge for line replacement. On the other hand, the first connection part occupies a small number of metal film layers. Since there is no need for winding, the wiring space in the metal film layer is also small. Therefore, it can effectively improve the problem of the difficulty in arranging the first connection part caused by the positional conflict between the first connection part and other traces in the same layer. Furthermore, the shorter length of the first connection part can also reduce its load and reduce the voltage drop of the signal transmitted on the first connection part. [Attached Image Description]

Detailed Implementation Methods

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] With the continuous development of display technology, the design of the relative positional relationship between pixel circuits and light-emitting elements in pixels has become more flexible.

[0065] like Figure 1 As shown, Figure 1 This is a schematic diagram of a display panel structure in related technologies. The display panel includes pixels 101, each pixel 101 including a plurality of sub-pixels 102, and each sub-pixel 102 including a pixel circuit 103 and a light-emitting element 104 electrically connected to each other. In at least some pixels 101, the pixel circuit 103 and its corresponding light-emitting element 104 are relatively far apart, and they need to be connected by a connecting line.

[0066] However, given the current panel structure, the arrangement of connecting wires is quite difficult and can easily lead to some problems.

[0067] like Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of a structure of a single pixel 101 in related technologies. Figure 3 This is another structural diagram of a single pixel 101 in the related technology. In pixel 101, when the connecting lines 105 led out from different pixel circuits 103 extend toward their respective corresponding light-emitting elements 104, multiple connecting lines 105 will overlap. In order to avoid short circuits, at least some of the connecting lines 105 need to be connected by a bridge 106 to switch lines.

[0068] However, this would result in a significant number of interconnects 105 requiring at least two metal film layers. This not only complicates the film layer design of these interconnects 105 themselves, but also affects the routing of many other traces on the same layer. For example, during layout design, consideration must be given to whether the interconnects 105 will conflict with other traces on these two metal film layers, leading to difficulties in routing the interconnects 105.

[0069] To avoid overlapping between connecting wires 105, such as Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of another structure for a single pixel 101 in related technologies. Figure 5In another structural diagram of a single pixel 101 in the related technology, the connecting lines 105 can only avoid each other by winding. However, although this allows the connecting lines 105 to adopt a single-layer design and simplify the design of the film layer itself, the extension method of the connecting lines 105 becomes very complex. Moreover, the winding method of the connecting lines 105 corresponding to different pixels 101 is also different, which makes the design of the connecting lines 105 very difficult. In addition, after the connecting lines 105 are wound, they still occupy a large wiring space in the metal film layer, thus still affecting the arrangement of many other wirings in the same layer. For example, when the connecting lines 105 are wound, there will be a long longitudinal segment extending in the y direction. This segment will crowd out the wiring space of other longitudinal wirings extending in the y direction in the metal film layer, causing film layer position conflicts between different wirings.

[0070] To address this, embodiments of the present invention provide a display panel, such as... Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 7 This is another structural schematic diagram of the display panel provided in an embodiment of the present invention. The display panel includes a plurality of pixels 1, and each pixel 1 includes a plurality of sub-pixels 2. The colors of the plurality of sub-pixels 2 can be different. Each sub-pixel 2 includes a pixel circuit 3 electrically connected to a light-emitting element 4. In this embodiment of the present invention, the light-emitting element 4 can be an LED, specifically a Micro LED, Mini LED, etc.

[0071] In pixel 1, the light-emitting elements 4 of multiple sub-pixels 2 are arranged along the first direction x, and the pixel circuits 3 of multiple sub-pixels 2 are arranged along the first direction x. Furthermore, in at least one pixel 1, the arrangement order of the multiple light-emitting elements 4 is different from the arrangement order of the multiple pixel circuits 3; or, the arrangement order of the multiple pixel circuits 3 is different in at least two pixels 1; or, the arrangement order of the multiple light-emitting elements 4 is different in at least two pixels 1.

[0072] In this embodiment of the invention, the arrangement order of the light-emitting elements 4 and the arrangement order of the pixel circuits 3 can both be represented by the color arrangement order. It is understood that a pixel 1 includes multiple sub-pixels 2 of different colors, meaning that the light-emitting elements 4 included in these multiple sub-pixels 2 emit different colors of light; that is, the multiple light-emitting elements 4 in pixel 1 will each correspond to multiple different colors. Correspondingly, the pixel circuits 3 included in the multiple sub-pixels 2 are electrically connected to the light-emitting elements 4 of different emitting colors to provide the driving current required for different color brightness. Therefore, the multiple pixel circuits 3 in pixel 1 will also each correspond to multiple different colors, and the color corresponding to the pixel circuit 3 is the same as the color corresponding to the light-emitting element 4 connected to it.

[0073] For example, see Figure 6 and Figure 7 Pixel 1 contains multiple sub-pixels 2, including a first sub-pixel 2-1, a second sub-pixel 2-2, and a third sub-pixel 2-3, which are of different colors. For ease of understanding, the following description of this embodiment will use the example of the first sub-pixel 2-1 being a red sub-pixel, the second sub-pixel 2-2 being a green sub-pixel, and the third sub-pixel 2-3 being a blue sub-pixel.

[0074] In the first sub-pixel 2-1, pixel circuit 3 is the first pixel circuit 3-1, and light-emitting element 4 is the first light-emitting element 4-1. Both the first light-emitting element 4-1 and the first pixel circuit 3-1 are red. In the second sub-pixel 2-2, pixel circuit 3 is the second pixel circuit 3-2, and light-emitting element 4 is the second light-emitting element 4-2. Both the second light-emitting element 4-2 and the second pixel circuit 3-2 are green. In the third sub-pixel 2-3, pixel circuit 3 is the third pixel circuit 3-3, and light-emitting element 4 is the third light-emitting element 4-3. Both the third light-emitting element 4-3 and the third pixel circuit 3-3 are blue.

[0075] It can be understood that when the first light-emitting element 4-1, the second light-emitting element 4-2, and the third light-emitting element 4-3 are arranged in different orders, each arrangement order will correspond to an arrangement order of multiple colors. Similarly, when the first pixel circuit 3-1, the second pixel circuit 3-2, and the third pixel circuit 3-3 are arranged in different orders, each arrangement order will also correspond to an arrangement order of multiple colors.

[0076] For example, when the first light-emitting element 4-1, the second light-emitting element 4-2, and the third light-emitting element 4-3 are arranged in sequence, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in pixel 1 is "red-green-blue"; when the second light-emitting element 4-2, the first light-emitting element 4-1, and the third light-emitting element 4-3 are arranged in sequence, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in pixel 1 is "green-red-blue".

[0077] When the first pixel circuit 3-1, the second pixel circuit 3-2, and the third pixel circuit 3-3 are arranged in sequence, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1 is "red-green-blue"; when the second pixel circuit 3-2, the first pixel circuit 3-1, and the third pixel circuit 3-3 are arranged in sequence, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1 is "green-red-blue".

[0078] It should be noted that the arrangement directions described in this invention are all arrangement directions with a definite direction. For example, combined with Figure 17 The display panel includes a first edge 7 and a second edge 8 that are opposite each other in a first direction x. The direction from the first edge 7 to the second edge 8 is a third direction x3. The arrangement order of the pixel circuit 3, the arrangement order of the light-emitting elements 4, and the arrangement order of the colors in the embodiments of the present invention are all arranged in a third direction x3.

[0079] Based on the above analysis, the aforementioned statement that "in at least one pixel 1, the arrangement order of the multiple light-emitting elements 4 is different from the arrangement order of the multiple pixel circuits 3" can also be expressed as "in at least one pixel 1, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is different from the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3". Based on this feature, in one configuration method, see... Figure 6 In pixel 1-1, the first light-emitting element 4-1, the second light-emitting element 4-2, and the third light-emitting element 4-3 are arranged in sequence, and the third pixel circuit 3-3, the second pixel circuit 3-2, and the first pixel circuit 3-1 are arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in pixel 1-1 is "red-green-blue", and the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 is "blue-green-red".

[0080] The aforementioned "at least two pixels 1 have multiple pixel circuits 3 corresponding to different color arrangements" can also be expressed as "at least two pixels 1 have multiple pixel circuits 3 corresponding to different color arrangements". Based on this feature, in one configuration method, see [reference needed]. Figure 6 In the image, pixels 1-1 and 1-2 are arranged as follows: in pixel 1-2, the first pixel circuit 3-1, the second pixel circuit 3-2, and the third pixel circuit 3-3 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1-2 is "red-green-blue". In pixel 1-1, the third pixel circuit 3-3, the second pixel circuit 3-2, and the first pixel circuit 3-1 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1-1 is "blue-green-red".

[0081] The aforementioned "at least two pixels 1 have multiple light-emitting elements 4 arranged in different orders" can also be expressed as "at least two pixels 1 have multiple light-emitting elements 4 corresponding to multiple colors arranged in different orders". Based on this feature, in one setting method, see [reference needed]. Figure 7In the image, pixels 1-3 and 1-2 are arranged as follows: in pixel 1-2, the first light-emitting element 4-1, the second light-emitting element 4-2, and the third light-emitting element 4-3 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in pixel 1-2 is "red-green-blue". In pixel 1-3, the third light-emitting element 4-3, the second light-emitting element 4-2, and the first light-emitting element 4-1 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in pixel 1-3 is "blue-green-red".

[0082] Furthermore, it should be noted that the pixel circuit corresponding to the red light-emitting element in this application may be temporarily referred to as the red pixel circuit, but this does not mean that the color of this pixel circuit is red, but rather that it controls the red light-emitting element to emit light. In the arrangement order of the pixel circuits mentioned in this application, where the color arrangement order differs, the color of the corresponding electrically connected light-emitting element is used to refer to the color of the pixel circuit.

[0083] In this embodiment of the invention, the arrangement order of pixel circuits 3 and / or light-emitting elements 4 in at least some pixels 1 is adjusted. This adjustment is specifically applicable to pixels 1 where the pixel circuits 3 and light-emitting elements 4 need to be connected via a first connecting portion 10, thereby allowing for greater flexibility in the arrangement of the first connecting portion 10. For example, when the pixel circuits 3 and light-emitting elements 4 are far apart in some pixels 1, compared to... Figure 2 , Figure 4 and Figure 6 Compared to the conventional arrangement of pixel circuit 3 and light-emitting element 4 in related technologies, the present invention, by changing the arrangement order of pixel circuit 3 and / or light-emitting element 4, allows the multiple first connection portions 10 corresponding to pixel 1 to avoid each other without winding, thus preventing overlap.

[0084] Therefore, by adopting the technical solution provided by the embodiments of the present invention, the wiring of the first connection part 10 corresponding to pixel 1 can be optimized: under the premise of avoiding the first connection part 10 winding as much as possible, more first connection parts 10 can adopt a single-layer design. On the one hand, it can simplify the design of the film layer of the first connection part 10 itself, without the need to set up a bridge for line replacement. On the other hand, the first connection part 10 occupies a small number of metal film layers. Since there is no need to wind, the wiring space in the metal film layer is also small. Therefore, it can effectively improve the problem of the difficulty in arranging the first connection part 10 caused by the positional conflict between the first connection part 10 and other traces in the same layer. Furthermore, the first connection part 10 is shorter in length, which can also reduce its load and reduce the voltage drop of the signal transmitted on the first connection part 10.

[0085] More specifically, in the embodiments of the present invention, combined with Figure 14 , Figure 16 ,as well as Figures 22-29 Pixel 1 includes a first type of pixel 11 and a second type of pixel 12. The distance between the pixel circuit 3 and its corresponding light-emitting element 4 in the first type of pixel 11 is greater than the distance between the pixel circuit 3 and its corresponding light-emitting element 4 in the second type of pixel 12.

[0086] The first type of pixel 11 includes a first pixel 13, in which the pixel circuit 3 and the corresponding light-emitting element 4 are connected by a first connecting part 10.

[0087] In the first pixel 13, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is different from the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3; or, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in the first pixel 13 and the second type of pixel 12 is different; or, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 in the first pixel 13 and the second type of pixel 12 is different.

[0088] Compared to the second type of pixel 12, by adjusting the arrangement order of the pixel circuit 3 and / or the arrangement order of the light-emitting element 4 in the first pixel 13, the design of the first connecting part 10 corresponding to the first pixel 13 can become relatively free. The first connecting parts 10 can avoid each other without winding, and the arrangement and film layer design of the first connecting parts 10 are better.

[0089] Regarding the connection of the light-emitting element 4, as follows: Figures 8-10 As shown, Figure 8 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 9 This is a cross-sectional structural diagram of a display panel provided in an embodiment of the present invention. Figure 10 This is a schematic diagram of another cross-sectional structure of the display panel provided in an embodiment of the present invention. The display panel further includes a first electrode 5, a second electrode 6, and a first power signal line. Figure 8 and Figure 9 (Not illustrated in the image). The first electrode 5 is electrically connected to the first electrode of both the pixel circuit 3 and the light-emitting element 4, and the second electrode 6 is electrically connected to both the first power signal line and the second electrode of the light-emitting element 4. Further details can be found in the following documentation. Figure 9 In some pixels, the corresponding first electrode 5 is directly electrically connected to the pixel circuit 3, see [reference]. Figure 10 In some pixels, the corresponding first electrode 5 is electrically connected to the pixel circuit 3 through the first connection part 10.

[0090] In this embodiment of the invention, the first power signal line can be disposed on the same layer as the first electrode 5 and the second electrode 6. In one configuration, such as... Figure 11 As shown, Figure 11This is a top view of the light-emitting element 4, the first electrode 5, the second electrode 6, and the first power signal line PVEE provided in an embodiment of the present invention. The first power signal line PVEE can be a mesh structure, in which case multiple second electrodes 6 are connected to the first power signal line PVEE. Alternatively, in another configuration, such as... Figure 12 As shown, Figure 12 This is another top view of the light-emitting element 4, the first electrode 5, the second electrode 6, and the first power signal line PVEE provided in the embodiment of the present invention. The first power signal line PVEE can also be a planar structure with a cutout 01. The first electrode 5 is located in the cutout 01 and is electrically insulated from the first power signal line PVEE. In this case, a portion of the first power signal line PVEE is reused as the second electrode 6.

[0091] In one feasible implementation, such as Figure 13 As shown, Figure 13 This is a schematic diagram of a pixel 1 provided in an embodiment of the present invention. The pixel 1 contains multiple sub-pixels 2, including a first sub-pixel 2-1, a second sub-pixel 2-2, and a third sub-pixel 2-3. In at least one pixel 1, the light-emitting elements 4 of the first sub-pixel 2-1 and the second sub-pixel 2-2 are arranged adjacently, and the pixel circuits 3 are arranged adjacently. Furthermore, the arrangement order of the light-emitting elements 4 in the first sub-pixel 2-1 and the second sub-pixel 2-2 is the opposite of the arrangement order of the pixel circuits 3; that is, the arrangement order of the two colors corresponding to the light-emitting elements 4 in the first sub-pixel 2-1 and the second sub-pixel 2-2 is the opposite of the arrangement order of the two colors corresponding to the pixel circuits 3.

[0092] For example, the first light-emitting element 4-1, the second light-emitting element 4-2 and the third light-emitting element 4-3 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is "red-green-blue". The second pixel circuit 3-2, the first pixel circuit 3-1 and the third pixel circuit 3-3 are arranged in sequence, and the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 is "green-red-blue".

[0093] contrast Figure 2 , Figure 4 and Figure 13 Compared to the conventional arrangement of pixel circuits 3 and light-emitting elements 4 in related technologies, the present invention reverses the arrangement order of pixel circuits 3 and / or light-emitting elements 4 in the first sub-pixel 2-1 and the second sub-pixel 2-2. In this pixel 1, at most, only the first connecting part 10 corresponding to the third pixel circuit 3-3 needs to be wound to ensure that the three first connecting parts 10 do not overlap at all, resulting in a more optimized arrangement of the first connecting parts 10.

[0094] For at least some pixels 1, when the arrangement order of the light-emitting elements 4 and pixel circuits 3 of at least two sub-pixels 2 in pixel 1 is inconsistent, in one configuration, the arrangement order of multiple light-emitting elements 4 in different pixels 1 can be kept the same, and only the arrangement order of multiple pixel circuits 3 in pixel 1 needs to be adjusted. This ensures that the light-emitting elements 4 of all pixels 1 follow a uniform arrangement order, preventing local display differences and resulting in a better display effect on the display panel.

[0095] Of course, in some optional embodiments of this application, for at least a portion of pixels 1, when the arrangement order of the light-emitting elements 4 and pixel circuits 3 of at least two sub-pixels 2 in pixel 1 is inconsistent, the light-emitting elements 4 and pixel circuits 3 in this portion of pixels 1 can also be designed in reverse order, so that the arrangement of the first connecting portion 10 will be more optimal. For example, see Figure 14 and Figure 15 The first pixel 13 shown contains a first light-emitting element 4-1, a second light-emitting element 4-2, and a third light-emitting element 4-3 arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is "red-green-blue". The third pixel circuit 3-3, the second pixel circuit 3-2, and the first pixel circuit 3-1 are arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 is "blue-green-red".

[0096] In one feasible implementation, such as Figure 14 As shown, Figure 14 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Pixel 1 includes a first type of pixel 11 and a second type of pixel 12. The distance between the pixel circuit 3 and its corresponding light-emitting element 4 in the first type of pixel 11 is greater than the distance between the pixel circuit 3 and its corresponding light-emitting element 4 in the second type of pixel 12.

[0097] At least in the same second type of pixel 12, the arrangement order of multiple light-emitting elements 4 is the same as the arrangement order of multiple pixel circuits 3, that is, the arrangement order of multiple colors corresponding to multiple light-emitting elements 4 is the same as the arrangement order of multiple colors corresponding to multiple pixel circuits 3.

[0098] For example, in the second type of pixel 12, the first light-emitting element 4-1, the second light-emitting element 4-2 and the third light-emitting element 4-3 are arranged in sequence, and the first pixel circuit 3-1, the second pixel circuit 3-2 and the third pixel circuit 3-3 are arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 and the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 are both "red-green-blue".

[0099] Among them, the second type of pixel 12 can be regarded as a regular pixel in the display panel. The pixel circuit 3 and the light-emitting element 4 in this type of pixel are still arranged in the original way.

[0100] The first type of pixel 11 includes a first pixel 13. At least in the same first pixel 13, the arrangement order of the multiple light-emitting elements 4 is different from the arrangement order of the multiple pixel circuits 3. That is, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is different from the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3.

[0101] For example, in the first pixel 13, the first light-emitting element 4-1, the second light-emitting element 4-2 and the third light-emitting element 4-3 are arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is "red-green-blue"; the third pixel circuit 3-3, the second pixel circuit 3-2 and the first pixel circuit 3-1 are arranged in sequence. At this time, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 is "blue-green-red".

[0102] For the second type of pixel 12, since the pixel circuit 3 and its corresponding light-emitting element 4 are relatively close, even if the pixel circuit 3 and light-emitting element 4 in this part of the pixel still follow the conventional arrangement order, the connection between the pixel circuit 3 and its corresponding light-emitting element 4 is also very simple, for example, see [reference needed]. Figure 20 and Figure 21 The pixel circuit 3 can be directly connected to the first electrode 5 and its corresponding light-emitting element 4, without the need for a connection between them.

[0103] For the first pixel 13, since the pixel circuit 3 and its corresponding light-emitting element 4 are far apart, the pixel circuit 3 and the light-emitting element 4 need to be connected by the first connecting part 10. By adjusting the arrangement order of the pixel circuit 3 and / or the arrangement order of the light-emitting element 4 in the first pixel 13, the design of the first connecting part 10 corresponding to the first pixel 13 can be made relatively free, so that the first connecting part 10 can avoid overlapping between different first connecting parts 10 while minimizing wire wrapping.

[0104] To further optimize the arrangement of the first connecting parts 10, so that the first connecting parts 10 corresponding to the first pixel 13 do not need to be wound, thus overcoming the overlap problem, such as... Figure 15 As shown, Figure 15 This is a schematic diagram of a structure of a first pixel 13 provided in an embodiment of the present invention. In at least a portion of the first pixel 13, the arrangement order of the plurality of light-emitting elements 4 is opposite to the arrangement order of the plurality of pixel circuits 3. That is, the arrangement order of the plurality of colors corresponding to the plurality of light-emitting elements 4 is opposite to the arrangement order of the plurality of colors corresponding to the plurality of pixel circuits 3.

[0105] In one feasible implementation, see Figure 14 In different first pixels 13, the arrangement order of multiple light-emitting elements 4 is the same, and the arrangement order of multiple pixel circuits 3 is the same. That is, the arrangement order of multiple colors corresponding to multiple light-emitting elements 4 is the same, and the arrangement order of multiple colors corresponding to multiple pixel circuits 3 is the same.

[0106] This arrangement unifies the arrangement order of the light-emitting elements 4 of different first pixels 13, and also unifies the arrangement order of the pixel circuits 3 of different first pixels 13. This makes the arrangement order of the pixel circuits 3 and light-emitting elements 4 of the first pixel 13 more regular. For example, see... Figure 14 The two first-type first pixels 25 shown in the diagram have the same arrangement order of light-emitting elements 4 and pixel circuit 3. Therefore, when designing the first connecting portions 10 corresponding to these two first-type first pixels 25, the extension methods of these two first connecting portions 10 are similar, which can reduce the layout design difficulty of the first connecting portions 10. Moreover, the light-emitting elements 4 in different first pixels 13 follow the same arrangement order, which can also reduce the display differences between different first pixels 13.

[0107] In one feasible implementation, see Figure 14 In the first pixel 13 and the second type of pixel 12, the arrangement order of the multiple light-emitting elements 4 is the same, that is, the arrangement order of the multiple colors corresponding to the multiple light-emitting elements 4 is the same.

[0108] This configuration does not change the original arrangement of the light-emitting elements 4 in the first pixel 13, but only changes the arrangement of the pixel circuits 3 in the first pixel 13 to make the arrangement of the light-emitting elements 4 different from that of the pixel circuits 3. Compared with adjusting the arrangement of the light-emitting elements 4 and the pixel circuits 3 at the same time, this method achieves the goal of optimizing the arrangement of the first connecting part 10 while making less modification to the original structure of the first pixel 13, thus reducing the design difficulty.

[0109] Furthermore, in the manufacturing process of LED display panels, the LEDs are first picked up from the growth substrate, then transferred to the driving backplane, and then bonded to the first electrode 5 and the second electrode 6. Since this arrangement does not change the original arrangement order of the light-emitting elements 4 in the first pixel 13, it will not affect the order of the light-emitting elements 4 grown on the growth substrate, or the picking and transfer of the light-emitting elements 4.

[0110] Alternatively, in another feasible implementation, such as Figure 16 As shown, Figure 16This is another structural schematic diagram of the display panel provided in an embodiment of the present invention. In the first pixel 13 and the second type of pixel 12, the arrangement order of the multiple pixel circuits 3 is the same, that is, the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 is the same.

[0111] This configuration does not change the original arrangement of the pixel circuits 3 in the first pixel 13, but only changes the arrangement of the light-emitting elements 4 in the first pixel 13 to make the arrangement of the light-emitting elements 4 different from that of the pixel circuits 3. Compared with adjusting the arrangement of the light-emitting elements 4 and the pixel circuits 3 at the same time, this method achieves the goal of optimizing the arrangement of the first connecting part 10 while making less modification to the original structure of the first pixel 13, thus reducing the difficulty of circuit design.

[0112] In one feasible implementation, combined with Figure 17 ,as well as Figures 22-29 The display panel includes a first outer edge 14 extending along a first direction x. The embodiment of the present invention is illustrated by taking the first outer edge 14 as the edge of the lower frame of the display panel.

[0113] In the first pixel 13, the pixel circuit 3 and the light-emitting element 4 are electrically connected through a first connecting portion 10. The first connecting portion 10 extends from the side of the pixel circuit 3 near the first outer edge 14 and is electrically connected to the light-emitting element 4 on the side of the light-emitting element 4 near the same first outer edge 14. Specifically, the first connecting portion 10 is connected to the light-emitting element 4 on the side of the light-emitting element 4 near the first outer edge 14 via a first electrode 5. That is, the first connecting portion 10 is connected to the first electrode 5 corresponding to the light-emitting element 4 on the side near the first outer edge 14.

[0114] In this structure, the first connection portions 10 corresponding to different first pixels 13 are all led out from the same side of the pixel circuit 3. That is, the output terminals of this part of the pixel circuit 3 are all designed on the same side. This eliminates the need for additional adjustments to the output terminals of different pixel circuits 3, keeping the layout design of this part of the pixel circuit 3 consistent and simplifying the layout design. Similarly, the first connection portions 10 corresponding to different first pixels 13 are also electrically connected to the light-emitting element 4 (first electrode 5) on the same side. Therefore, when designing the connection vias between the first electrode 5 and the first connection portions 10, the connection vias are also located on the same side of the first electrode 5, and the position of the connection vias is unified, which can further simplify the layout design.

[0115] In one feasible implementation, such as Figure 17 and Figure 18 As shown, Figure 17This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 18 This is another schematic diagram of the structure of the display panel provided in an embodiment of the present invention. The display panel further includes a display area 15, which includes a first area 16 and a second area 17. The first area 16 is located on the side of the second area 17 closer to the edge of the display panel. That is, the first area 16 is an edge display area closer to the outer edge of the display panel, and the second area 17 is a middle display area.

[0116] Wherein, the first type of pixel 11 is located in the first region 16, the second type of pixel 12 is located in the second region 17, and along the first direction x and / or the second direction y, the spacing between at least some adjacent pixel circuits 3 in the first type of pixel 11 is smaller than the spacing between adjacent pixel circuits 3 in the second type of pixel 12, wherein the second direction y intersects the first direction x.

[0117] Specifically, "the spacing between at least some adjacent pixel circuits 3 in the first type of pixel 11 is smaller than the spacing between adjacent pixel circuits 3 in the second type of pixel 12 along the first direction x and / or the second direction y" may include: see [link to relevant documentation] Figure 17 and Figure 18 The spacing d1 between at least two adjacent first-class pixels 11 in the first direction x is less than the spacing d2 between at least two adjacent second-class pixels 12 in the first direction x; and / or, see Figure 17 and Figure 18 The spacing d3 between at least two adjacent first-class pixels 11 in the second direction y is less than the spacing d4 between at least two adjacent second-class pixels 12 in the second direction y; and / or, see Figure 18 The spacing d5 between two adjacent pixel circuits 3 in at least a portion of the first type of pixels 11 is smaller than the spacing d6 between two adjacent pixel circuits 3 in at least a portion of the second type of pixels 12.

[0118] Or, in another way of expressing it, such as Figure 19 As shown, Figure 19 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Multiple pixel circuits 3 in pixel 1 constitute a circuit unit 18. The display area 15 includes multiple circuit rows 19 arranged along a second direction y, and each circuit row 19 includes multiple circuit units 18 arranged along a first direction x. The multiple circuit rows include a first circuit row 20 and a second circuit row 21. The first circuit row 20 is located on at least one side of the second circuit row 21 in the second direction y, that is, the first circuit row 20 is closer to the outer edge of the display panel. Furthermore, the distance between adjacent first circuit rows 20 is less than the distance between adjacent second circuit rows 21.

[0119] The display area 15 also includes a plurality of circuit columns 22 arranged along a first direction x, and each circuit column 22 includes a plurality of circuit units 18 arranged along a second direction y. The plurality of circuit columns 22 includes a first circuit column 23 and a second circuit column 24. The first circuit column 23 is located on at least one side of the second circuit column 24 in the first direction x, i.e., the first circuit column 23 is closer to the outer edge of the display panel. Furthermore, the distance between adjacent first circuit columns 23 is less than the distance between adjacent second circuit columns 24, and / or, the spacing between two adjacent pixel circuits 3 in the circuit units 18 of the first circuit column 23 is less than the spacing between two adjacent pixel circuits 3 in the circuit units 18 of the second circuit column 24.

[0120] In the first type of pixel 11, the pixel circuit 3 is located in the first circuit row 20 and the first circuit column 23, and in the second type of pixel 12, the pixel circuit 3 is located in the second circuit row 21 and the second circuit column 24.

[0121] The above structure involves recessing the pixel circuit 3 near the edge of the display panel towards the second region 17, thereby increasing the distance between this portion of the pixel circuit 3 and the outer edge of the display panel. This reduces the risk of transistor failure in this portion of the pixel circuit 3 when the edge of the display panel is cut using laser cutting technology.

[0122] This setup is more suitable for display panels with narrow bezels or no bezels. The bezel width of such display panels is very small, and the cutting edge of the display panel is closer to the pixel circuit 3 at the edge position. With the above design, the problem of transistor failure caused by cutting in such display panels can be effectively improved.

[0123] In one feasible implementation, see Figure 17 In a direction perpendicular to the plane of the display panel, at least some of the pixel circuits 3 and their corresponding light-emitting elements 4 in the first type of pixels 11 do not overlap, and the light-emitting elements 4 are closer to the outer edge of the display panel than the pixel circuits 3, so as to keep these pixel circuits 3 away from the outer edge of the display panel and reduce the risk of transistor failure caused by the cutting process.

[0124] In a direction perpendicular to the plane of the display panel, the pixel circuit 3 and its corresponding light-emitting element 4 in the second type of pixel 12 overlap. Specifically, as shown... Figure 20 and Figure 21 As shown, Figure 20 This is a schematic diagram of a structure of the second type of pixel 12 provided in an embodiment of the present invention. Figure 21This is a schematic diagram of a film structure of a second type of pixel 12 provided in an embodiment of the present invention. The pixel circuit 3 and its corresponding light-emitting element 4 in the second type of pixel 12 are very close to each other. This part of the pixel circuit 3 can be connected to the light-emitting element 4 only through the first electrode 5.

[0125] Furthermore, the relative positional relationship between the pixel circuit 3 and the light-emitting element 4 in the first type of pixel 11 is different at different locations, and correspondingly, the wiring method of the first connecting part 10 is also different. The wiring method of the first connecting part 10 corresponding to different first pixels 13 will be described in detail below.

[0126] In pixel 1, multiple light-emitting elements 4 constitute a light-emitting unit 29, and multiple pixel circuits 3 constitute a circuit unit 18.

[0127] In one feasible implementation, combined with Figure 16 and Figure 17 ,like Figure 22 and Figure 23 As shown, Figure 22 This is a schematic diagram of a structure of the first pixel 25 provided in an embodiment of the present invention. Figure 23 This is a schematic diagram of a film structure of a first pixel 25 provided in an embodiment of the present invention. The first pixel 13 includes the first pixel 25.

[0128] In the first type of first pixel 25, the orthographic projection of the light-emitting unit 29 on the plane of the display panel and the orthographic projection of the circuit unit 18 on the plane of the display panel do not overlap in the first direction x and the second direction y, while the second direction y intersects the first direction x. Furthermore, in the first type of first pixel 25, the arrangement order of the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of pixel circuits 3; that is, the arrangement order of the various colors corresponding to the plurality of light-emitting elements 4 is the opposite of the arrangement order of the various colors corresponding to the plurality of pixel circuits 3.

[0129] Among them, combined Figure 17 , Figure 22 The four first-type first pixels 25 shown can be regarded as the first-type first pixels 25 at the four top corners of the display panel.

[0130] See Figure 22 In the two first-type first pixels 25 above: In at least part of the first-type first pixels 25, the distance between the circuit unit 18 and the first outer edge 14 is less than the distance between the light-emitting unit 29 and the first outer edge, and the first connection part 10 corresponding to this part of the first-type first pixel 25 is led out from the side of the pixel circuit 3 near the first outer edge 14, and extended from the side of the circuit unit 18 near the light-emitting unit 29 in the first direction x to the side of the light-emitting element 4 near the same first outer edge 14 and electrically connected to the light-emitting element 4.

[0131] And / or, see Figure 22 The following two first-type first pixels 25: In at least part of the first-type first pixels 25, the distance between the circuit unit 18 and the first outer edge 14 is greater than the distance between the circuit unit 18 and the first outer edge 14, and the first connection portion 10 corresponding to the first-type first pixel 25 is led out from the side of the pixel circuit 3 near the first outer edge 14, and extended by the light-emitting unit 29 in the first direction x near the side of the circuit unit 18 to the side of the light-emitting element 4 near the first outer edge 14 and electrically connected to the light-emitting element 4.

[0132] In comparison with related technologies Figure 2 and Figure 4 For the first type of first pixel 25 where the light-emitting unit 29 and the circuit unit 18 do not overlap in the first direction x and the second direction y, based on the above setting, the multiple first connecting portions 10 corresponding to this first type of first pixel 25 can achieve non-overlapping without winding, and the film layer design of the first connecting portion 10 is more optimized.

[0133] Furthermore, when the light-emitting unit 29 and the circuit unit 18 do not overlap in either the first direction x or the second direction y, taking the first type of first pixel 25, which is closer to the first outer edge 14 of the circuit unit 18, as an example, by making the first connecting portion 10 corresponding to this first type of first pixel 25 extend from the side of the circuit unit 18 closer to the light-emitting unit 29 in the first direction x, the wiring length of the first connecting portion 10 can be further reduced. This not only further reduces the wiring space of the first connecting portion 10 and reduces positional conflicts with other traces on the same layer, but also further reduces its load.

[0134] Furthermore, in the above configuration, the first connection portions 10 corresponding to different first-type first pixels 25 are all led out on the same side of the pixel circuit 3, and are also electrically connected to the light-emitting element 4 (first electrode 5) on the same side. This allows the output terminals of the pixel circuit 3 in the first-type first pixel 25 to be designed on the same side, and the connection vias between the first electrode 5 and the first connection portion 10 corresponding to the first-type first pixel 25 are also designed on the same side of the first electrode 5, which can further simplify the layout design.

[0135] In one feasible implementation, combined with Figure 16 and Figure 17 ,like Figure 24 and Figure 25 As shown, Figure 24 This is a schematic diagram of a second type of first pixel 26 provided in an embodiment of the present invention. Figure 25This is a schematic diagram of a film structure for a second type of first pixel 26 provided in an embodiment of the present invention. The first pixel 13 includes the second type of first pixel 26.

[0136] In the second type of first pixel 26, the orthographic projection of the light-emitting unit 29 on the plane of the display panel and the orthographic projection of the circuit unit 18 on the plane of the display panel do not overlap in the first direction x, but overlap in the second direction y. Furthermore, at least some of the orthographic projections of the pixel circuits 3 on the plane of the display panel and their corresponding light-emitting elements 4 on the plane of the display panel do not overlap. The second direction y intersects the first direction x. In addition, in the second type of first pixel 26, the arrangement order of the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of pixel circuits 3; that is, the arrangement order of the various colors corresponding to the plurality of light-emitting elements 4 is the opposite of the arrangement order of the various colors corresponding to the plurality of pixel circuits 3.

[0137] Among them, combined Figure 17 , Figure 24 The four second type first pixels 26 shown can be regarded as the second type first pixels 26 at the four top corners of the display panel.

[0138] See Figure 24 The two second-type first pixels 26 above: In at least some of the second-type first pixels 26, the distance between the circuit unit 18 and the first outer edge 14 is less than the distance between the light-emitting unit 29 and the first outer edge 14, and the first connection portion 10 corresponding to the second-type first pixel 26 is led out from the side of the pixel circuit 3 near the first outer edge 14, and extends from the side of the circuit unit 18 in the first direction x to the side of the light-emitting element 4 near the first outer edge 14 and is electrically connected to the light-emitting element 4.

[0139] And / or, see Figure 24 The following two second-type first pixels 26: In at least some of the second-type first pixels 26, the distance between the circuit unit 18 and the first outer edge 14 is greater than the distance between the circuit unit 18 and the first outer edge 14, and the first connection portion 10 corresponding to the second-type first pixel 26 is led out from the side of the pixel circuit 3 near the first outer edge 14, and extends from the side of the light-emitting unit 29 in the first direction x to the side of the light-emitting element 4 near the first outer edge 14 and is electrically connected to the light-emitting element 4.

[0140] In comparison with related technologies Figure 3 and Figure 5 For the second type of first pixel 26 where the light-emitting unit 29 and the circuit unit 18 overlap in the first direction x but do not overlap in the second direction y, based on the above configuration, the multiple first connecting portions 10 corresponding to this second type of first pixel 26 can achieve non-overlapping without complex winding, and the film layer design of the first connecting portion 10 is better.

[0141] Moreover, based on the above configuration, although the light-emitting unit 29 and the circuit unit 18 overlap in the second direction y in this type of pixel, by extending the corresponding first connection portion 10 from one side of the circuit unit 18 or the light-emitting unit 29 to the light-emitting element 4, the overlap between the first connection portion 10 and the pixel circuit 3 can be avoided, thereby reducing the crosstalk between the signals transmitted by the internal wiring of the first connection portion 10 and the pixel circuit 3.

[0142] Furthermore, in the above configuration, the first connection portions 10 corresponding to the different second-type first pixels 26 are all led out on the same side of the pixel circuit 3, and are also electrically connected to the light-emitting element 4 (first electrode 5) on the same side. This allows the output terminals of the pixel circuit 3 in the second-type first pixels 26 to be designed on the same side, and the connection vias between the first electrode 5 and the first connection portion 10 corresponding to the second-type first pixels 26 are also designed on the same side of the first electrode 5, which can further simplify the layout design.

[0143] In one feasible implementation, combined with Figure 16 and Figure 17 ,like Figure 26 and Figure 27 As shown, Figure 26 This is a schematic diagram of a third type of first pixel 27 provided in an embodiment of the present invention. Figure 27 This is a schematic diagram of a film structure for a third type of first pixel 27 provided in an embodiment of the present invention. The first pixel 13 includes the third type of first pixel 27.

[0144] In the third type of first pixel 27, the light-emitting unit 29 and the circuit unit 18 are arranged along the first direction x. Furthermore, in the third type of first pixel 27, the arrangement order of the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of pixel circuits 3, that is, the arrangement order of the plurality of colors corresponding to the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of colors corresponding to the plurality of pixel circuits 3.

[0145] The first connection portion 10 corresponding to the third type of first pixel 27 is led out from the side of pixel circuit 3 near the first outer edge 14 and extends to the side of light-emitting element 4 near the first outer edge 14 and is electrically connected to light-emitting element 4.

[0146] Among them, combined Figure 17 , Figure 26 The two third-type first pixels 27 shown can be regarded as third-type first pixels 27 that are close to the first edge 7 and the second edge 8 respectively.

[0147] For the third type of first pixel 27, where the light-emitting unit 29 and the circuit unit 18 are arranged along the first direction x, the above-described arrangement allows the multiple first connection portions 10 corresponding to the third type of first pixel 27 to avoid overlapping without winding, resulting in a better film layer design for the first connection portions 10. Furthermore, in the above-described arrangement, the first connection portions 10 corresponding to different third types of first pixels 27 are all led out from the same side of the pixel circuit 3 and are electrically connected to the light-emitting element 4 (first electrode 5) on the same side. This simplifies the layout design and further reduces the extension length of the first connection portions 10, thus lowering their load.

[0148] In one feasible implementation, combined with Figure 16 and Figure 17 ,like Figure 28 and Figure 29 As shown, Figure 28 This is a schematic diagram of a fourth type of first pixel 28 provided in an embodiment of the present invention. Figure 29 This is a schematic diagram of a film structure of a fourth type of first pixel 28 provided in an embodiment of the present invention. The first pixel 13 includes the fourth type of first pixel 28.

[0149] In the fourth type of first pixel 28, in a direction perpendicular to the plane of the display panel, the light-emitting unit 29 overlaps with the circuit unit 18, and at least some of the pixel circuits 3 and their corresponding light-emitting elements 4 do not overlap. Furthermore, in the fourth type of first pixel 28, the arrangement order of the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of pixel circuits 3, that is, the arrangement order of the plurality of colors corresponding to the plurality of light-emitting elements 4 is the opposite of the arrangement order of the plurality of colors corresponding to the plurality of pixel circuits 3.

[0150] The first connection portion 10 corresponding to the fourth first pixel 28 is led out from the side of the pixel circuit 3 near the first outer edge 14 and extends to the side of the light-emitting element 4 near the first outer edge 14 and is electrically connected to the light-emitting element 4.

[0151] Among them, combined Figure 17 , Figure 28 The two fourth type of first pixel 28 shown can be regarded as the fourth type of first pixel 28 that are close to the first edge 7 and the second edge 8 respectively.

[0152] For the fourth type of first pixel 28 where the light-emitting unit 29 overlaps with the circuit unit 18, the above-described arrangement allows the multiple first connection portions 10 corresponding to the fourth type of first pixel 28 to avoid overlapping without needing to be wound, resulting in a better film layer design for the first connection portions 10. Furthermore, in the above arrangement, the first connection portions 10 corresponding to different fourth types of first pixels 28 are all led out from the same side of the pixel circuit 3 and are electrically connected to the light-emitting element 4 (first electrode 5) on the same side. This simplifies the layout design and further reduces the extension length of the first connection portions 10, thus lowering their load.

[0153] In one feasible implementation, such as Figures 30-32 As shown, Figure 30 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Figure 31 This is a schematic diagram of a structure of the second pixel 30 provided in an embodiment of the present invention. Figure 32 This is a schematic diagram of a film structure of the second pixel 30 provided in an embodiment of the present invention. The first type of pixel 11 also includes the second pixel 30.

[0154] In at least a portion of the second pixel 30, the orthographic projection of the light-emitting unit 29 on the plane of the display panel does not overlap with the orthographic projection of the circuit unit 18 on the plane of the display panel in the first direction x. Furthermore, in the same second pixel 30, the arrangement order of the plurality of light-emitting elements 4 is the same as the arrangement order of the plurality of pixel circuits 3, that is, the arrangement order of the plurality of colors corresponding to the plurality of light-emitting elements 4 is the same as the arrangement order of the plurality of colors corresponding to the plurality of pixel circuits 3.

[0155] In the second pixel 30, the pixel circuit 3 and the light-emitting element 4 are electrically connected through the second connection part 31. The second connection part 31 is led out from the side of the pixel circuit 3 near the light-emitting unit 29 in the second direction y, and is electrically connected to the light-emitting element 4 on the side of the light-emitting element 4 near the circuit unit 18 in the second direction y. The second direction y intersects with the first direction x.

[0156] For the pixels where the light-emitting unit 29 and the circuit unit 18 do not overlap in the first direction x, the output terminals of the pixel circuit 3 in at least some pixels can be reversed so that the pixel circuit 3 is led out from the side of the pixel circuit 3 closer to the light-emitting unit 29 in the second direction y. In this way, without changing the arrangement order of the pixel circuit 3 and the light-emitting element 4, the second connection part 31 can avoid each other without complicated winding.

[0157] Furthermore, such as Figure 33 As shown, Figure 33This is a schematic diagram of a film layer structure of a display panel provided in an embodiment of the present invention. At least a portion of the pixel circuits 3 in the second pixels 30, after being flipped about a first direction x-axis, have the same pattern as the pixel circuits 3 in the second type of pixels 12. Specifically, at least a portion of the pixel circuits 3 in the second pixels 30, after being rotated 180° about a first direction x-axis on the plane of the display panel, have the same pattern as the pixel circuits 3 in the second type of pixels 12.

[0158] This method involves flipping the pattern of at least a portion of the pixel circuit 3 in the second pixel 30, thereby moving the output terminal A of the pixel circuit 3, which is electrically connected to the first connection portion 10, to the side closer to the light-emitting unit 29 in the second direction y. In this way, the pattern design of the second pixel 30 and the pixel circuit 3 in the second type of pixel 12 remains the same, which simplifies the layout design.

[0159] Further, see Figure 30 In the second pixel 30, the side of the pixel circuit 3 closest to the light-emitting unit 29 in the second direction y is the side of the pixel circuit 3 closest to the edge of the display panel in the second direction y, thereby enabling this part of the pixel circuit 3 to achieve an inward design.

[0160] In one feasible implementation, such as Figure 34 As shown, Figure 34 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. Multiple pixel circuits 3 in pixel 1 constitute a circuit unit 18, and multiple circuit units 18 arranged along the second direction y constitute a circuit column 22. The second direction y intersects with the first direction x.

[0161] The display panel also includes multiple first data line groups 32, each first data line group 32 corresponding to a circuit column 22, and the first data line group 32 is located on one side of the corresponding circuit column 22 in the first direction x. The first data line group 32 includes multiple first data lines Data1 arranged along the first direction x, and the multiple pixel circuits 3 of each circuit unit 18 in the circuit column 22 are electrically connected to the multiple first data lines Data1 of their corresponding first data line group 32.

[0162] Typically, the spacing between two adjacent circuit units 18 is greater than the distance between two adjacent pixel circuits 3 in the circuit unit 18. Therefore, by placing the first data line group 32 on one side of the circuit unit 18 in the first direction x, the space between adjacent circuit units 18 can be reasonably utilized, avoiding the first data line Data1 from crowding out the space between two adjacent pixel circuits 3 in the circuit unit 18 and affecting the arrangement of other same-layer traces in that space.

[0163] In one feasible implementation, see again Figure 34The same first data line Data1 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2. The arrangement order of the multiple first data lines Data1 in the first data line group 32 is the same as the arrangement order of the multiple pixel circuits 3 in the second type of pixel 12.

[0164] It should be noted that since the same first data line Data1 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2, each first data line Data1 will also correspond to a color, and the color corresponding to the first data line Data1 is the same as the color corresponding to the pixel circuit 3 it is connected to. Therefore, the arrangement order of multiple first data lines Data1 in the first data line group 32 can also be represented by the arrangement order of colors.

[0165] For example, see Figure 34 The first data line group 32 includes multiple first data lines Data1, including a first sub-data line Data1-1, a second sub-data line Data1-2, and a third sub-data line Data1-3. The first sub-data line Data1-1 is electrically connected to the first pixel circuit 3-1 and its corresponding color is red; the second sub-data line Data1-2 is electrically connected to the second pixel circuit 3-2 and its corresponding color is green; the third sub-data line Data1-3 is electrically connected to the third pixel circuit 3-3 and its corresponding color is blue.

[0166] In the second type of pixel 12, the first pixel circuit 3-1, the second pixel circuit 3-2, and the third pixel circuit 3-3 are arranged sequentially, and the corresponding arrangement order of the various colors is "red-green-blue". In the first data line group 32, the first sub-data line Data1-1, the second sub-data line Data1-2, and the third sub-data line Data1-3 are arranged sequentially, and the corresponding arrangement order of the various colors is also "red-green-blue".

[0167] That is, "the arrangement order of multiple first data lines Data1 in the first data line group 32 is the same as the arrangement order of multiple pixel circuits 3 in the second type of pixel 12" can also be expressed as "the arrangement order of multiple colors corresponding to multiple first data lines Data1 in the first data line group 32 is the same as the arrangement order of multiple colors corresponding to multiple pixel circuits 3 in the second type of pixel 12, wherein the color corresponding to the first data line Data1 is the same as the color corresponding to the pixel circuit 3 connected to it.

[0168] With this configuration, the arrangement order of multiple first data lines Data1 in different first data line groups 32 is consistent, and the connection order of multiple first data lines Data1 in different first data line groups 32 with the original interface in the driver chip is consistent, so there is no need to match different interface orders for different first data line groups 32.

[0169] Alternatively, in another feasible implementation, combined with Figure 19 ,like Figure 35 As shown, Figure 35 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The circuit column 22 includes a first circuit column 23 and a second circuit column 24.

[0170] The same first data line Data1 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2.

[0171] The first data line group 32 includes a first type of first data line group 33 electrically connected to the first circuit column 23 and a second type of first data line group 34 electrically connected to the second circuit column 24.

[0172] The arrangement order of the multiple first data lines Data1 in the first data line group 33 of the first type is different from the arrangement order of the multiple first data lines Data1 in the second data line group 34. In conjunction with the foregoing analysis, that is, the arrangement order of the various colors corresponding to the multiple first data lines Data1 in the first data line group 33 of the first type is different from the arrangement order of the various colors corresponding to the multiple first data lines Data1 in the second data line group 34, wherein the color corresponding to the first data line Data1 is the same as the color corresponding to the pixel circuit 3 connected to it.

[0173] Under this structure, the arrangement order of the first data line Data1 in the first data line group 32 is more flexible, which makes it easier to optimize the arrangement of the first connection traces 35 between the pixel circuit 3 and the first data line Data1 in different circuit columns 22.

[0174] For example, see again Figure 35 The arrangement order of the multiple pixel circuits 3 in the first pixel 13 is different from the arrangement order of the multiple pixel circuits 3 in the second type of pixel 12. Furthermore, the arrangement order of the multiple pixel circuits 3 in different first pixels 13 can be the same.

[0175] The first circuit column 23 includes pixel circuit 3 in the first pixel 13, for example, it only includes pixel circuit 3 in the first pixel 13. The second circuit column 24 includes at least pixel circuit 3 in the second type of pixel 12, for example, it includes pixel circuit 3 in both the first pixel 13 and the second type of pixel 12.

[0176] In this configuration, the arrangement order of the multiple first data lines Data1 in the first data line group 33 is the same as the arrangement order of the multiple pixel circuits 3 in the first pixel 13. That is, the arrangement order of the multiple colors corresponding to the multiple first data lines Data1 in the first data line group 33 is the same as the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in the first pixel 13.

[0177] The arrangement order of the multiple first data lines Data1 in the second type of first data line group 34 is the same as the arrangement order of the multiple pixel circuits 3 in the second type of pixel 12. That is, the arrangement order of the multiple colors corresponding to the multiple first data lines Data1 in the second type of first data line group 34 is the same as the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in the second type of pixel 12.

[0178] After adjusting the arrangement order of pixel circuits 3 in the first pixel 13, the arrangement order of multiple first data lines Data1 in the first data line group 33 of the first type is further adjusted to make the order the same. This makes the routing method of the first connection trace 35 between pixel circuits 3 in the first pixel 13 and the first data lines Data1 in the first data line group 33 of the first type the same as the routing method of the first connection trace 35 between pixel circuits 3 in the second type pixel 12 and the first data lines Data1 in the second data line group 34 of the second type, simplifying the layout design of this part of the first connection trace 35.

[0179] In one feasible implementation, such as Figure 36 and Figure 37 As shown, Figure 36 This is a schematic diagram of a film layer structure of a display panel provided in an embodiment of the present invention. Figure 37 for Figure 36 In a cross-sectional view along the A1-A2 direction, the pixel circuit 3 is electrically connected to the first data line Data1 via a first connecting trace 35. The first connecting trace 35 is located on one side of the pixel circuit 3 in the second direction y, and the first connecting trace 35 and the first data line Data1 are disposed on different layers. In this way, the first connecting trace 35 will not short-circuit with other first data lines Data1 when connected to its corresponding first data line Data1.

[0180] In addition, see Figure 36 and Figure 38 , Figure 38 This is a schematic diagram of another film layer structure of the display panel provided in an embodiment of the present invention. For the connected pixel 1 and the first data line group 32, regardless of whether the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1 is the same as or different from the arrangement order of the multiple colors corresponding to the multiple first data lines Data1 in the first data line group 32, when the pixel circuit 3 is connected to the corresponding first data line Data1 through the first connection trace 35, there will be no positional conflict between the multiple first connection traces 35, and the wiring of the first connection trace 35 is relatively flexible.

[0181] In one feasible implementation, such as Figure 39 As shown, Figure 39This is another structural schematic diagram of the display panel provided in an embodiment of the present invention. The display panel further includes a plurality of second data line groups 37. Each second data line group 37 corresponds to a circuit column 22. Each second data line group 37 includes a plurality of second data lines Data2 arranged along a first direction x. The plurality of pixel circuits 3 of each circuit unit 18 in the circuit column 22 are electrically connected to the plurality of second data lines Data2 of the corresponding second data line group 37.

[0182] For the first data line group 32 and the second data line group 37 connected to the same circuit column 22, the first data line group 32 and the second data line group 37 are located on opposite sides of the circuit column 22, and the first data line group 32 and the second data line group 37 are arranged alternately in the first direction x.

[0183] On the one hand, placing the second data line group 37 on one side of the circuit column 22 can prevent the second data line Data2 from crowding the space between two adjacent pixel circuits 3 in the circuit unit 18 and affecting the arrangement of other traces on the same layer in that space. On the other hand, the first data line group 32 and the second data line group 37 are located on opposite sides of the circuit column 22, and the connection distance between the pixel circuit 3 and the first data line Data1 and the second data line Data2 is approximately equal, which can reduce the attenuation difference between the two data voltages during transmission.

[0184] Furthermore, see again Figure 39 The same first data line Data1 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2, and the same second data line Data2 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2.

[0185] For the first data line group 32 and the second data line group 37 connected to the same circuit column 22, the arrangement order of the multiple second data lines Data2 in the second data line group 37 is the same as the arrangement order of the multiple first data lines Data1 in the first data line group 32.

[0186] Similar to "first data line Data1", when the same second data line Data2 is electrically connected to the pixel circuit 3 in the same color sub-pixel 2, each second data line Data2 will also correspond to a color, and the color corresponding to the second data line Data2 is the same as the color corresponding to the pixel circuit 3 it is connected to. Therefore, the arrangement order of multiple second data lines Data2 in the second data line group 37 can also be represented by the color arrangement order.

[0187] For example, see Figure 39The second data line group 37 contains multiple second data lines Data2, including a fourth sub-data line Data2-1, a fifth sub-data line Data2-2, and a third sub-data line Data2-3. The fourth sub-data line Data2-1 is electrically connected to the first pixel circuit 3-1 and corresponds to the color red; the fifth sub-data line Data2-2 is electrically connected to the second pixel circuit 3-2 and corresponds to the color green; and the sixth sub-data line Data2-3 is electrically connected to the third pixel circuit 3-3 and corresponds to the color blue.

[0188] That is, "for the first data line group 32 and the second data line group 37 connected to the same circuit column 22, the arrangement order of multiple second data lines Data2 in the second data line group 37 is the same as the arrangement order of multiple first data lines Data1 in the first data line group 32" can also be expressed as "for the first data line group 32 and the second data line group 37 connected to the same circuit column 22, the arrangement order of multiple colors corresponding to multiple second data lines Data2 in the second data line group 37 is the same as the arrangement order of multiple colors corresponding to multiple first data lines Data1 in the first data line group 32. Among them, the color corresponding to the first data line Data1 is the same as the color corresponding to the pixel circuit 3 connected to it, and the color corresponding to the second data line Data2 is the same as the color corresponding to the pixel circuit 3 connected to it."

[0189] In the above configuration, the first data line Data1 in the first data line group 32 and the second data line Data2 in the second data line group 37 follow the same arrangement order, making the arrangement of the data lines more regular and simplifying the design of the connection lines between the pixel circuit 3 and the data lines.

[0190] Of course, in other embodiments of the present invention, for the first data line group 32 and the second data line group 37 connected to the same circuit column 22, the arrangement order of the multiple colors corresponding to the multiple second data lines Data2 in the second data line group 37 may also be different from the arrangement order of the multiple colors corresponding to the multiple first data lines Data1 in the first data line group 32.

[0191] In addition, see Figure 36 and Figure 38 The pixel circuit 3 is electrically connected to the second data line Data2 through the second connection trace 40. The second connection trace 40 and the first connection trace 35 are located on opposite sides of the pixel circuit 3 in the second direction y, and the second connection trace 40 can be set on the same layer as the first connection trace 35.

[0192] However, it should be noted that, see Figure 36 and Figure 38For the connected pixel 1 and the second data line group 37, regardless of whether the arrangement order of the multiple colors corresponding to the multiple pixel circuits 3 in pixel 1 is the same as or different from the arrangement order of the multiple colors corresponding to the multiple second data lines Data2 in the second data line group 37, when the pixel circuit 3 is connected to the corresponding second data line Data2 through the second connection trace 40, there will be no positional conflict between the multiple second data lines Data2, and the routing of the second data lines Data2 is relatively flexible.

[0193] In one feasible implementation, such as Figure 40 As shown, Figure 40 This is a schematic diagram of a circuit structure for the pixel circuit 3 provided in an embodiment of the present invention. Figure 41 This is a schematic diagram of a film structure for a pixel circuit 3 provided in an embodiment of the present invention. The pixel circuit 3 includes a pulse width modulation module (PWM) and an amplitude adjustment module (PAM). The first data line Data1 in the first data line group 32 is electrically connected to one of the PWM module and the PAM module. This invention is illustrated using the example of the first data line Data1 being electrically connected to the amplitude adjustment module PAM.

[0194] Among them, the pulse width modulation module PWM is used to adjust the light emission duty cycle of the light-emitting element 4, that is, the light emission period of the light-emitting element 4, and the amplitude adjustment module PAM is used to control the amplitude of the drive current. The combined effect of the pulse width modulation module PWM and the amplitude adjustment module PAM is to adjust the grayscale or brightness displayed by the light-emitting element 4.

[0195] The following embodiments of the present invention are used as examples. Figure 40 Taking the pixel circuit 3 as an example, one circuit structure will be described.

[0196] The pulse width modulation (PWM) module may include:

[0197] First driving transistor M1.

[0198] The first gate reset transistor M2 has its gate electrically connected to the first scan line PWM-S1, its first terminal electrically connected to the first reset signal line PAWM-REF, and its second terminal electrically connected to the gate of the first drive transistor M1.

[0203] The first light-emitting control transistor M6 has its gate electrically connected to the first light-emitting control signal line PWM-EM, its first terminal electrically connected to the first fixed potential signal line PWM-vdd, and its second terminal electrically connected to the first terminal of the first driving transistor M1.

[0204] The gate of the second light-emitting control transistor M7 is electrically connected to the first light-emitting control signal line PWM-EM, and the first terminal is electrically connected to the second terminal of the first driving transistor M1.

[0205] The amplitude adjustment module (PAM) may include:

[0206] The first plate of the second capacitor C2 is electrically connected to the second electrode of the second light-emitting control transistor M7.

[0207] The gate of the second driving transistor M8 is electrically connected to the second plate of the second capacitor C2.

[0208] The second gate reset transistor M9 has its gate electrically connected to the third scan line PAM-S1, its first terminal electrically connected to the second reset signal line PAM-REF, and its second terminal electrically connected to the gate of the second drive transistor M8.

[0209] The second data writing transistor M10 has its gate electrically connected to the fourth scan line PAM-S2, its first terminal electrically connected to the amplitude adjustment data line PAM-Data, and its second terminal electrically connected to the first terminal of the second driving transistor M8.

[0210] The second compensation transistor M11 has its gate electrically connected to the fourth scan line PAM-S2, its first terminal electrically connected to the second terminal of the second driving transistor M8, and its second terminal electrically connected to the gate of the second driving transistor M8.

[0211] The anode reset transistor M12 has its gate electrically connected to the fourth scan line PAM-S2, its first electrode electrically connected to the first power signal line PVEE, and its second electrode electrically connected to the light-emitting element 4.

[0212] The third light-emitting control transistor M13 has its gate electrically connected to the second light-emitting control transistor PAM-EM, its first terminal electrically connected to the second fixed potential signal line PAM-vdd, and its second terminal electrically connected to the first terminal of the second driving transistor M8.

[0213] The fourth light-emitting control transistor M14 has its gate electrically connected to the second light-emitting control transistor PAM-EM, its first electrode electrically connected to the second electrode of the second driving transistor M8, and its second electrode electrically connected to the light-emitting element 4.

[0214] Among them, the first data line Data1 can be the amplitude adjustment data line PAM-Data, and the second data line Data2 can be the pulse width modulation data line PWM-Data.

[0215] In one feasible implementation, such as Figure 42 As shown, Figure 42 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The pixel circuit 3 includes a first driving module 38, which is a pulse width modulation module (PWM) and / or an amplitude adjustment module (PAM). This embodiment of the present invention illustrates an example where the first driving module 38 is an amplitude adjustment module (PAM).

[0216] In the first pixel 13, the pixel circuit 3 is electrically connected to the light-emitting element 4 through the first connection part 10. The first connection part 10 is led out from the first driving module 38, and the sequence of the pixel circuit 3 is the same as the sequence of the first driving module 38.

[0217] The first driving module 38 is a module in the pixel circuit 3 that is electrically connected to the light-emitting element 4. Therefore, using the order of the first driving module 38 to characterize the order of the pixel circuit 3 can better reflect the influence of the arrangement order of the pixel circuit 3 on the wiring method of the first connection part 10.

[0218] The order of pixel circuit 3 and the order of the first driving module 38 can both be represented by the order of their corresponding colors. For example, see... Figure 42In the first pixel circuit 3-1, the amplitude adjustment module PAM is the first amplitude adjustment module PAM-1 and the pulse width modulation module PWM is the first pulse width modulation module PWM-1; in the second pixel circuit 3-2, the amplitude adjustment module PAM is the second amplitude adjustment module PAM-2 and the pulse width modulation module PWM is the second pulse width modulation module PWM-2; in the third pixel circuit 3-3, the amplitude adjustment module PAM is the third amplitude adjustment module PAM-3 and the pulse width modulation module PWM is the third pulse width modulation module PWM-3.

[0219] When the first driving module 38 is the amplitude adjustment module PAM, the first pixel circuit 3-1, the second pixel circuit 3-2 and the third pixel circuit 3-3 are arranged in sequence, which means that the first amplitude adjustment module PAM-1, the second amplitude adjustment module PAM-2 and the third amplitude adjustment module PAM-3 are arranged in sequence.

[0220] In one feasible implementation, such as Figure 43 As shown, Figure 43 This is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The pixel circuit 3 includes a first driving module 38 and a second driving module 39, wherein the first driving module 38 and the second driving module 39 are respectively one of a pulse width modulation module (PWM) and an amplitude adjustment module (PAM). This embodiment of the present invention is illustrated by taking the first driving module 38 as the amplitude adjustment module (PAM) and the second driving module 39 as the pulse width modulation module (PWM).

[0221] At least in the first pixel 13, the arrangement order of the plurality of first driving modules 38 is different from the arrangement order of the plurality of second driving modules 39. That is, at least in the first pixel 13, the arrangement order of the various colors corresponding to the plurality of first driving modules 38 is different from the arrangement order of the various colors corresponding to the plurality of second driving modules 39. The color corresponding to the first driving module 38 is the same as the color corresponding to the light-emitting element 4 connected to it, and the color corresponding to the second driving module 39 is the same as the color corresponding to the light-emitting element 4 coupled to it.

[0222] In the first pixel 13, the pixel circuit 3 is electrically connected to the light-emitting element 4 through the first connection part 10. The first connection part 10 is led out from the first driving module 38, and the sequence of the pixel circuit 3 is the same as the sequence of the first driving module 38.

[0223] The first driving module 38 is the module in the pixel circuit 3 that is electrically connected to the light-emitting element 4. Therefore, using the order of the first driving module 38 to represent the order of the pixel circuit 3 better reflects the influence of adjusting the arrangement order of the pixel circuit 3 on the wiring method of the first connection part 10. As for the second driving module 39, the second driving module 39 can be arranged in a different order than the first driving module 38 to make the design more flexible.

[0224] Alternatively, in another feasible implementation, see [link to relevant documentation]. Figure 43 At least in the first pixel 13, the arrangement order of the multiple colors corresponding to the multiple first driving modules 38 and the arrangement order of the multiple colors corresponding to the multiple second driving modules 39 can also be the same.
