Description

Technical Field

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

[0002] Organic light-emitting diodes (OLEDs) are a new type of display technology with many advantages that other display technologies cannot match, such as wide viewing angle, high contrast, fast response, low power consumption and foldability, making them highly competitive in the next generation of displays.

[0003] With the continuous development of display technology and public demand, the pursuit of high screen-to-body ratios and even full-screen display panels for superior visual experience has become a trend in the mobile electronic device market in recent years. However, due to the presence of essential components on the front panel of mobile electronic devices, such as cameras, infrared sensors, and iris cameras, perforations are required in the screen. Currently, the industry commonly uses under-display camera (CUP) technology, which can significantly improve the screen-to-body ratio. However, existing CUP technologies still face many constraints, such as structural design. For example, to ensure sufficient light transmission, the camera area is often designed with a low pixel density (Pixels Per Inch, PPI), which can lead to poor display quality when the camera area is used as a display. On the other hand, to ensure a sufficiently high pixel density, the light transmission in that area must be sacrificed. In other words, insufficient light transmission will not meet the camera's shooting requirements and will affect image quality.

[0004] Furthermore, with the development of display technology, transparent display technology has emerged. A transparent display typically refers to a display screen where users can see objects behind it through the display surface. Transparent displays can be used for novel applications such as shop windows, conference rooms, or signage. A transparent display generally includes a light-transmitting area and an opaque area for mounting elements. The opaque area houses the pixel elements to display the content, while the light-transmitting area allows light to pass through, thus combining transparency and display characteristics. Currently, in transparent displays, improper pixel placement in the opaque area often leads to wasted space, hindering the improvement of pixel density and ensuring display quality. Therefore, how to increase pixel density to maintain display quality while simultaneously ensuring a sufficiently large light-transmitting area to enhance transparency is a hot research topic in this field.

[0005] Therefore, providing a display panel and display device that can meet the light transmittance requirements while also having a high PPI to ensure display quality, thereby improving light transmittance and maximizing display effect, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a display panel and a display device to solve the problem that the display effect and light transmission performance cannot be well balanced in existing displays using under-display camera technology or existing transparent displays.

[0007] This invention discloses a display panel, comprising: a first display area; the first display area includes multiple pixel units and multiple light-transmitting areas, the multiple pixel units are arranged along a first direction to form a pixel unit row, and the multiple pixel units are arranged along a second direction to form a pixel unit column, wherein the first direction and the second direction intersect; each pixel unit includes at least a first sub-pixel, a second sub-pixel, and a third sub-pixel of different colors; in a pixel unit, the first sub-pixel includes a first side and a second side, the first side and the second side having an intersection point; the second sub-pixel is disposed adjacent to the first sub-pixel on one side of the first side, and the third sub-pixel is disposed adjacent to the first sub-pixel on one side of the second side; four pixel units form a repeating unit, the first display area includes multiple repeating units arranged in an array, at least four repeating units are disposed around a light-transmitting area; the four pixel units of a repeating unit include a first pixel unit, a second pixel unit, a third pixel unit, and a fourth pixel unit; wherein the first pixel unit and the second pixel unit are located in the same pixel unit row. The third and fourth pixel units are located in the same pixel unit row; the first and third pixel units are located in the same pixel unit column, and the second and fourth pixel units are located in the same pixel unit column; in the four pixel units of a repeating unit, along the first direction, the first sub-pixel of the first pixel unit is adjacent to the first sub-pixel of the second pixel unit, the first sub-pixel of the third pixel unit is adjacent to the first sub-pixel of the fourth pixel unit, the second sub-pixel of the first pixel unit is adjacent to the second sub-pixel of the second pixel unit, and the second sub-pixel of the third pixel unit is adjacent to the second sub-pixel of the fourth pixel unit; along the second direction, the first sub-pixel of the first pixel unit is adjacent to the first sub-pixel of the third pixel unit, the first sub-pixel of the second pixel unit is adjacent to the first sub-pixel of the fourth pixel unit, the third sub-pixel of the first pixel unit is adjacent to the third sub-pixel of the third pixel unit, and the third sub-pixel of the second pixel unit is adjacent to the third sub-pixel of the fourth pixel unit.

[0008] Based on the same inventive concept, the present invention also discloses a display device, which includes a photosensitive device and the aforementioned display panel, wherein the photosensitive device is located in a first display area.

[0009] Compared with the prior art, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0010] The sub-pixel arrangement in the first display area of ​​the display panel provided by this invention not only ensures a sufficiently large light-transmitting area, improving the light transmittance of the first display area, but also allows each repeating unit in the first display area to include four pixel units, resulting in higher pixel density and better display quality. This not only further enhances display quality but also ensures image quality when the first display area is used as a camera area. Because the sub-pixel arrangement in the first display area provided by this invention allows four adjacent first sub-pixels of the same color to share an opening in a metal mask for vapor deposition within a repeating unit, two adjacent second sub-pixels of the same color to share an opening in a metal mask for vapor deposition, and two adjacent third sub-pixels of the same color to share an opening in a metal mask for vapor deposition, this not only reduces the number of openings in the metal mask used in the manufacturing process, preventing the metal mask from becoming weak due to excessive number and small size of openings, thus improving the strength of the metal mask, but also achieves a high pixel density pixel arrangement structure with fewer openings, improving the display quality of the resulting display panel.

[0011] Of course, any product implementing this invention need not necessarily achieve all of the technical effects described above at the same time.

Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of a planar structure of a display panel provided in an embodiment of the present invention. Figure 2 yes Figure 1 A partially enlarged structural diagram of the first display area in the middle.Figure 3 yes Figure 2 A schematic diagram of the structure of a repeating unit. The display panel 000 provided in this embodiment includes: a first display area AA1;

[0044] The first display area AA1 includes multiple pixel units 00 and multiple light-transmitting areas 01. The multiple pixel units 00 are arranged along the first direction X to form a pixel unit row 00H, and the multiple pixel units 00 are arranged along the second direction Y to form a pixel unit column 00L, wherein the first direction X and the second direction Y intersect.

[0045] Each pixel unit 00 includes at least a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30 of different colors; in a pixel unit 00, the first sub-pixel 10 includes a first side 10A and a second side 10B, and the first side 10A and the second side 10B have an intersection point O; the second sub-pixel 20 is disposed adjacent to the first sub-pixel 10 on one side of the first side 10A, and the third sub-pixel 30 is disposed adjacent to the first sub-pixel 10 on one side of the second side 10B;

[0046] Four pixel units 00 form a repeating unit Q. The first display area AA1 includes multiple repeating units Q arranged in an array. At least four repeating units Q are arranged around a light-transmitting area 01.

[0047] A repeating unit Q comprises four pixel units 00, including a first pixel unit 001, a second pixel unit 002, a third pixel unit 003, and a fourth pixel unit 004; wherein the first pixel unit 001 and the second pixel unit 002 are located in the same pixel unit row 00H, and the third pixel unit 003 and the fourth pixel unit 003 are located in the same pixel unit row 00H; the first pixel unit 001 and the third pixel unit 003 are located in the same pixel unit column 00L, and the second pixel unit 002 and the fourth pixel unit 004 are located in the same pixel unit column 00L;

[0048] In a repeating unit Q, among the four pixel units 00, along the first direction X, the first sub-pixel 10 of the first pixel unit 001 is adjacent to the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003 is adjacent to the first sub-pixel 10 of the fourth pixel unit 004, the second sub-pixel 20 of the first pixel unit 001 is adjacent to the second sub-pixel 20 of the second pixel unit 002, and the second sub-pixel 20 of the third pixel unit 003 is adjacent to the second sub-pixel 20 of the fourth pixel unit 004; along the second direction Y, the first sub-pixel 10 of the first pixel unit 001 is adjacent to the first sub-pixel 10 of the third pixel unit 003, the first sub-pixel 10 of the second pixel unit 002 is adjacent to the first sub-pixel 10 of the fourth pixel unit 004, the third sub-pixel 30 of the first pixel unit 001 is adjacent to the third sub-pixel 30 of the third pixel unit 003, and the third sub-pixel 30 of the second pixel unit 002 is adjacent to the third sub-pixel 30 of the fourth pixel unit 004.

[0049] Specifically, the display panel 000 provided in this embodiment can be a transparent display panel using organic light-emitting diode (OLED) display technology, or it can be a display panel using OLED display technology that can accommodate photosensitive devices such as under-display cameras. The display panel 000 provided in this embodiment includes a first display area AA1, which includes multiple pixel units 00 and multiple light-transmitting areas 01. Optionally, when the display panel 000 is a transparent display panel, the area where the multiple pixel units 00 of the first display area AA1 are located can be used to set up pixel structures to display the image to be displayed using the pixel units 00, while the multiple light-transmitting areas 01 of the first display area AA1 allow light to pass through, thus achieving the dual characteristics of transparency and display in the display panel 000. Optionally, when the display panel 000 is a display panel capable of housing photosensitive devices such as an under-display camera, the first display area AA1 can be used as a camera setting area. The area where the multiple pixel units 00 of the first display area AA1 are located can be used to set the pixel structure. When the display panel 000 is in display mode, the first display area AA1 can perform its normal display function. When the display panel 000 is in shooting mode, the multiple light-transmitting areas 01 of the first display area AA1 can allow ambient light to pass through, thereby capturing images of the outside world. It is understood that in this embodiment... Figure 1 and Figure 2 The illustrated display panels are all examples of display panels that use organic light-emitting diode (OLED) display technology and can accommodate photosensitive devices such as under-display cameras. In specific implementations, the display panel provided in this embodiment can also be a transparent display panel using organic light-emitting diode (OLED) display technology, which will not be elaborated here.

[0050] In this embodiment, the first display area AA1 of the display panel 000 includes multiple pixel units 00 and multiple light-transmitting areas 01. The multiple pixel units 00 are arranged along a first direction X to form a pixel unit row 00H, and the multiple pixel units 00 are arranged along a second direction Y to form a pixel unit column 00L. The multiple pixel unit rows 00H can be arranged sequentially along the second direction Y, and the multiple pixel unit columns 00L can be arranged sequentially along the first direction X; wherein, the first direction X and the second direction Y intersect; optionally, the first direction X and the second direction Y can be two directions parallel to the light-emitting surface of the display panel 000 that intersect or are perpendicular to each other. Figure 1 The example is given by taking the first direction X and the second direction Y as being perpendicular to each other in a direction parallel to the light-emitting surface of the display panel 000.

[0051] Each pixel unit 00 in this embodiment includes at least a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30 of different colors; that is, at least three different colors of sub-pixels form a pixel unit 00. Optionally, for example, if the first sub-pixel 10 is a green sub-pixel, then the second sub-pixel 20 can be a red sub-pixel, and the third sub-pixel 30 can be a blue sub-pixel; or if the first sub-pixel 10 is a red sub-pixel, then the second sub-pixel 20 can be a blue sub-pixel, and the third sub-pixel 30 can be a green sub-pixel; or if the first sub-pixel 10 is a blue sub-pixel, then the second sub-pixel 20 can be a green sub-pixel, and the third sub-pixel 30 can be a red sub-pixel. This embodiment does not impose specific limitations. Figure 2 and Figure 3 Different subpixels of different colors are distinguished by different fill patterns.

[0052] In a pixel unit 00 composed of sub-pixels of different colors, the first sub-pixel 10 includes a first side 10A and a second side 10B connected together, that is, the first side 10A and the second side 10B have an intersection point O. The second sub-pixel 20 is set on one side of the first side 10A and adjacent to the first sub-pixel 10, while the third sub-pixel 30 is set on one side of the second side 10B and adjacent to the first sub-pixel 10. It can be understood that in this embodiment, "adjacent" means that no other sub-pixels are set between two adjacent sub-pixels; thus, these two sub-pixels can be understood as adjacent sub-pixels. That is, the two sub-pixels of a pixel unit 00 are respectively located on one side of the two connected sides of another sub-pixel, such as... Figure 2 and Figure 3As shown, taking the square shape of the orthographic projection of the first sub-pixel 10 on the light-emitting surface of the display panel 000 as an example, the first side 10A and the second side 10B of the first sub-pixel 10 with the square orthographic projection shape are the two connected sides of the square. The second sub-pixel 20 and the third sub-pixel 30 are respectively disposed on one side of the two connected sides, forming a structure in which the second sub-pixel 20 and the third sub-pixel 30 partially surround the first sub-pixel 10. The four pixel units 00 shown above form a repeating unit Q in the first display area AA1 of this embodiment. Multiple repeating units Q are arranged in an array within the first display area AA1, such that at least four repeating units Q are arranged around a light-transmitting area 01. Thus, the display panel of this embodiment includes multiple repeating units Q formed by four pixel units 00. The repeating units Q formed by the four pixel units 00 can realize the normal display function of the first display area AA1 when the display panel 000 is in the display state. The light-transmitting area 01 formed by at least four repeating units Q, excluding sub-pixels, is used for light transmission. When the display panel 000 is in the shooting state, ambient light is allowed to pass through, realizing the shooting of the outside scene. Optionally, when the display panel 000 is a transparent display panel, the light-transmitting area 01 can be used only for the transmission of light to achieve the transparency effect of the display panel 000, and the object behind the display panel 000 can be seen through the light-transmitting area 01.

[0053] In this embodiment, four pixel units 00 form a repeating unit Q in the first display area AA1. Specifically, the four pixel units 00 of a repeating unit Q are arranged around a center point, that is, the first pixel unit 001 and the second pixel unit 002 are located in the same pixel unit row 00H, and the third pixel unit 003 and the fourth pixel unit 003 are located in the same pixel unit row 00H; the first pixel unit 001 and the third pixel unit 003 are located in the same pixel unit column 00L, and the second pixel unit 002 and the fourth pixel unit 004 are located in the same pixel unit column 00L. Furthermore, along the first direction X, the sub-pixels of the same color in two adjacent pixel units 00 (first pixel unit 001 and second pixel unit 002, third pixel unit 003 and fourth pixel unit 003) are mirror symmetrical. Along the second direction Y, the sub-pixels of the same color in two adjacent pixel units 00 (first pixel unit 001 and third pixel unit 003, second pixel unit 002 and fourth pixel unit 004) are also mirror symmetrical. Figure 2 and Figure 3As shown, the final arrangement of the different color sub-pixels of the four pixel units 00 in a repeating unit Q is as follows: along the first direction X, the first sub-pixel 10 of the first pixel unit 001 is adjacent to the first sub-pixel 10 of the second pixel unit 002; the first sub-pixel 10 of the third pixel unit 003 is adjacent to the first sub-pixel 10 of the fourth pixel unit 004; the second sub-pixel 20 of the first pixel unit 001 is adjacent to the second sub-pixel 20 of the second pixel unit 002; the second sub-pixel 20 of the third pixel unit 003 is adjacent to the first sub-pixel 10 of the fourth pixel unit 004; the second sub-pixel 20 of the first pixel unit 001 is adjacent to the second sub-pixel 20 of the second pixel unit 002; and the second sub-pixel 20 of the third pixel unit 003 is adjacent to the first sub-pixel 10 of the fourth pixel unit 004. The second sub-pixel 20 of pixel unit 004 is arranged adjacent to each other; along the second direction Y, the first sub-pixel 10 of the first pixel unit 001 is arranged adjacent to the first sub-pixel 10 of the third pixel unit 003, the first sub-pixel 10 of the second pixel unit 002 is arranged adjacent to the first sub-pixel 10 of the fourth pixel unit 004, the third sub-pixel 30 of the first pixel unit 001 is arranged adjacent to the third sub-pixel 30 of the third pixel unit 003, and the third sub-pixel 30 of the second pixel unit 002 is arranged adjacent to the third sub-pixel 30 of the fourth pixel unit 004.

[0054] The arrangement of sub-pixels in the first display area AA1 in this embodiment not only ensures that the light-transmitting area 01 has a sufficiently large area, improving the light transmittance of the first display area AA1, but also allows each repeating unit Q in the first display area AA1 to include four pixel units 00, such as... Figure 4 As shown, Figure 4 It refers to the arrangement structure of different color subpixels in two repeating units within the display area in related technologies, compared to commonly used structures in related technologies such as... Figure 4 The arrangement of different color sub-pixels in a repeating unit Q' shown in this embodiment can increase the pixel density of the first display area AA1. Figure 4 In the illustrated related technology, a repeating unit Q' can only include two pixel units 00', while in this embodiment, a repeating unit Q can include four pixel units 00. Figure 2 and Figure 4 Based on having the same size light-transmitting area 01, so that both have the same sufficient amount of light transmission, Figure 2 and Figure 4 When the area of ​​a repeating unit is the same, the sub-pixel arrangement method provided in this embodiment can result in higher pixel density and better display quality, which is beneficial to further improve the display quality while also ensuring the imaging quality when the first display area AA1 is used as a camera area.

[0055] It is understood that in this embodiment Figure 4This is merely an illustration of a common subpixel arrangement in the prior art. In specific implementations, the subpixel arrangement in the prior art can also be other, but the number of pixel units included in a repeating unit is still relatively small. That is, the pixel arrangement of the first display area AA1 provided in this embodiment presents a higher pixel density. The specific pixel arrangement in the prior art will not be described in detail here.

[0056] Optional, such as Figure 2 and Figure 3 As shown, in this embodiment, in a repeating unit Q formed by four pixel units 00, four first sub-pixels 10 of the same color are close together, two second sub-pixels 20 of the same color are close together, and two third sub-pixels 30 of the same color are close together. In the manufacturing process of the display panel 000 using organic light-emitting diode display technology, the film formation technology of organic light-emitting materials is mainly based on vacuum evaporation. During the evaporation process, a high-precision metal mask (FMM) is used to limit the evaporation area of ​​different color light-emitting materials. Therefore, the sub-pixel arrangement of the first display area AA1 provided in this embodiment allows four adjacent first sub-pixels 10 of the same color to be deposited together through an opening of a metal mask in a repeating unit Q, two adjacent second sub-pixels 20 of the same color to be deposited together through an opening of a metal mask, and two adjacent third sub-pixels 30 of the same color to be deposited together through an opening of a metal mask. This not only reduces the number of openings in the metal mask used in the manufacturing process, avoiding a decrease in the strength of the metal mask due to an excessive number of openings or an excessively small size, thus improving the strength of the metal mask, but also achieves a high pixel density pixel arrangement structure with a metal mask with fewer openings, thereby improving the display quality of the manufactured display panel 000.

[0057] It should be noted that in this embodiment... Figures 1-3 The structure of the display panel is shown only as an example. In actual implementation, the structure of the display panel 000 includes, but is not limited to, this. It may also include other structures, such as the film layer structure, pixel circuit, driving circuit, packaging structure, etc. of the display panel 000. This embodiment will not elaborate on these details. For a more detailed understanding, please refer to the structure of organic light-emitting diode display panels in related technologies.

[0058] It should be further explained that in this embodiment... Figure 1 The image only illustrates the area and shape of the first display area AA1. In actual implementation, the area and shape of the first display area AA1 in the display panel 000 include, but are not limited to, [specific examples]. Figure 1As shown, the first display area AA1 can also be of other sizes and shapes, which are not limited in this embodiment. The figures in this embodiment only illustrate the size and shape of pixel unit 00 and the first sub-pixel 10, second sub-pixel 20, and third sub-pixel 30 in pixel unit 00. In specific implementation, the size and shape of pixel unit 00 and the first sub-pixel 10, second sub-pixel 20, and third sub-pixel 30 in pixel unit 00 include, but are not limited to, those of other types. Figure 2 and Figure 3 As shown, other sizes and shapes are also possible, but this embodiment does not limit them.

[0059] Optionally, in this embodiment, the first sub-pixel 10 can be a green sub-pixel, the second sub-pixel 20 can be a red sub-pixel, and the third sub-pixel 30 can be a blue sub-pixel. Since the luminous efficiency and lifespan of the blue organic light-emitting material used to make the blue sub-pixel are usually the lowest, the required light-emitting area needs to be correspondingly larger. The luminous efficiency and lifespan of the green organic light-emitting material used in the green sub-pixel are the next highest. Therefore, in this embodiment, the projected area of ​​the third sub-pixel 30 on the light-emitting surface of the display panel 000 can be larger than that of the first sub-pixel 10 on the light-emitting surface of the display panel 000. The projected area of ​​the glossy surface is such that the projected area of ​​the third sub-pixel 30 on the glossy surface of the display panel 000 can be larger than the projected area of ​​the second sub-pixel 20 on the glossy surface of the display panel 000, in order to compensate for the attenuation of the blue sub-pixel. The projected area of ​​the first sub-pixel 10 on the glossy surface of the display panel 000 is larger than the projected area of ​​the second sub-pixel 20 on the glossy surface of the display panel 000, in order to compensate for the attenuation of the green sub-pixel. This can improve the luminous efficiency and lifespan of the entire display panel 000, and help ensure the display quality of the first display area AA1 of the display panel 000.

[0060] In some alternative embodiments, please refer to the references. Figure 5 and Figure 6 In this embodiment, Figure 5 This is a schematic diagram of another planar structure of the display panel provided in an embodiment of the present invention. Figure 6 yes Figure 5 The diagram shows a partial enlarged view of the second display area. In this embodiment, the display panel 000 also includes a second display area AA2. At least a portion of the second display area AA2 is arranged adjacent to the first display area AA1. The transmittance of the first display area AA1 is greater than that of the second display area AA2.

[0061] This embodiment explains that the display panel 000 may further include a second display area AA2, at least a portion of which is arranged adjacent to the first display area AA1. Optionally, the second display area AA2 may be arranged around the first display area AA1 (e.g., Figure 5As shown in the figure), or the second display area AA2 can be partially set around the first display area AA1 (not shown in the figure). The transmittance of the first display area AA1 is greater than that of the second display area AA2, that is, the light transmittance of the first display area AA1 is greater than that of the second display area AA2. This allows the first display area AA1 to perform the display function, and can also be reused as a setting area for light-sensing elements (such as cameras). That is, the display panel 000 can set up light-sensing elements such as under-screen cameras within the range of the first display area AA1. Optionally, the light transmittance of the first display area AA1 can be greater than that of the second display area AA2 by setting the PPI (Pixels Per Inch, representing the number of pixels per inch of the display panel) in the first display area AA1 to be less than that in the second display area AA2, or by having a light-transmitting area 01 that the second display area AA2 does not have. This embodiment does not limit the structure of the display panel in the first display area AA1. In specific implementations, it can also be configured with other structures that can achieve a greater light transmittance in the first display area AA1 than in the second display area AA2. When the under-display camera or other photosensitive elements within the first display area AA1 are not working, the sub-pixels of different colors in the pixel 00 units within the first display area AA1 work together, allowing the second display area AA2 and the first display area AA1 to display the image together, achieving a full-screen display effect for the display panel 000. Furthermore, in this embodiment, the first display area AA1... Figure 2 The illustrated subpixel arrangement structure can further improve the display quality of the first display area AA1 by increasing the pixel density. When the under-display camera and other photosensitive elements within the first display area AA1 are working, the light-transmitting area 01 within the first display area AA1 allows the first display area AA1 to have a high light transmittance. The under-display camera and other photosensitive elements within the first display area AA1 can receive external light passing through the first display area AA1 to achieve setting functions (such as camera function). Thus, while realizing the display function of the first display area AA1, increasing the screen ratio, and achieving full-screen display, it can also provide conditions for the operation of photosensitive elements with high light transmittance, and realize the setting functions of the under-display camera and other photosensitive elements.

[0062] It is understood that this embodiment does not specifically limit the arrangement structure of the sub-pixels in the second display area AA2, as long as the display effect can be achieved. For details, please refer to the structure of organic light-emitting diode display panels in related technologies.

[0063] Optional, such as Figure 5 and Figure 6As shown, in the display panel 000 provided in this embodiment, the display panel 000 of the second display area AA2 includes a plurality of fourth sub-pixels 40, a plurality of fifth sub-pixels 50, and a plurality of sixth sub-pixels 60;

[0064] The arrangement of multiple fourth sub-pixels 40, multiple fifth sub-pixels 50, and multiple sixth sub-pixels 60 in the second display area AA2 is the same as the arrangement of multiple first sub-pixels 10, multiple second sub-pixels 20, and multiple third sub-pixels 30 in the first display area AA1. For example... Figure 6 As shown, the color of the fourth sub-pixel 40 can be the same as the color of the first sub-pixel 10, the color of the fifth sub-pixel 50 can be the same as the color of the second sub-pixel 20, and the color of the sixth sub-pixel 60 can be the same as the color of the third sub-pixel 30. That is, the arrangement of sub-pixels in the first display area AA1 and the second display area AA2 of the display panel 000 in this embodiment can be the same. The difference between the two display areas is that the first display area AA1 includes multiple light-transmitting areas 01, while the second display area AA2 does not have light-transmitting areas. This allows the transmittance of the first display area AA1 to be greater than that of the second display area AA2. At the same time, by having the same arrangement of sub-pixels as the first display area AA1, the number of openings in the metal mask used in the display panel manufacturing process of the second display area AA2 can be reduced, the strength of the metal mask can be increased, and the overall display quality of the resulting display panel 000 can be improved.

[0065] It is understood that, in this embodiment, the areas of the same color sub-pixels in the second display area AA2 and the first display area AA1 can be set to be different; or the areas of the same color sub-pixels in the second display area AA2 and the first display area AA1 can be set to be the same. This embodiment does not limit this, and the setting can be selected according to actual needs during specific implementation.

[0066] Optional, such as Figure 5 and Figure 7 As shown, Figure 7 yes Figure 5 Another partially enlarged structural diagram of the second display area. In this embodiment, the display panel 000 of the second display area AA2 includes a plurality of fourth sub-pixels 40, a plurality of fifth sub-pixels 50, and a plurality of sixth sub-pixels 60; the fourth sub-pixels 40, fifth sub-pixels 50, and sixth sub-pixels 60 are arranged alternately along the second direction Y to form a sub-pixel column 000L;

[0067] The display panel 000 of the second display area AA2 includes multiple repeating pixel columns QL, which are arranged along the first direction X; each repeating pixel column QL includes two sub-pixel columns 000L, which are the first sub-pixel column 000L1 and the second sub-pixel column 000L2, respectively.

[0068] In the first direction X, the fourth sub-pixel 40 of the first sub-pixel column 000L1 is located between the fifth sub-pixel 50 and the sixth sub-pixel 60 of the second sub-pixel column 000L2; the fifth sub-pixel 50 of the first sub-pixel column 000L1 is located between the fourth sub-pixel 40 and the sixth sub-pixel 60 of the second sub-pixel column 000L2; the sixth sub-pixel 60 of the first sub-pixel column 000L1 is located between the fourth sub-pixel 40 and the fifth sub-pixel 50 of the second sub-pixel column 000L2.

[0069] This embodiment explains that the arrangement of multiple fourth sub-pixels 40, multiple fifth sub-pixels 50, and multiple sixth sub-pixels 60 in the second display area AA2 may be different from the arrangement of multiple first sub-pixels 10, multiple second sub-pixels 20, and multiple third sub-pixels 30 in the first display area AA1. Specifically: the fourth sub-pixel 40, the fifth sub-pixel 50, and the sixth sub-pixel 60 are alternately arranged along the second direction Y to form a sub-pixel column 000L. The display panel 000 of the second display area AA2 may include multiple repeating pixel columns QL, and the multiple repeating pixel columns QL are arranged along the first direction X. Each repeating pixel column QL includes two sub-pixel columns 000L, namely the first sub-pixel column 000L1 and the second sub-pixel column 000L2. So that in the first direction X, the fourth sub-pixel 40 of the first sub-pixel column 000L1 is located between the fifth sub-pixel 50 and the sixth sub-pixel 60 of the second sub-pixel column 000L2; the fifth sub-pixel 50 of the first sub-pixel column 000L1 is located between the fourth sub-pixel 40 and the sixth sub-pixel 60 of the second sub-pixel column 000L2; the sixth sub-pixel 60 of the first sub-pixel column 000L1 is located between the fourth sub-pixel 40 and the fifth sub-pixel 50 of the second sub-pixel column 000L2. The arrangement of the fourth sub-pixel 40, the fifth sub-pixel 50, and the sixth sub-pixel 60 in the second display area AA2 of this embodiment can make a fourth sub-pixel 40, a fifth sub-pixel 50, and a sixth sub-pixel 60 of the same pixel unit 00P in the second display area AA2 arranged in a "pin" shape or an inverted "pin" shape or approximately in a "pin" shape. And the arrangement structure of the pixel unit 00P formed by a fourth sub-pixel 40, a fifth sub-pixel 50, and a sixth sub-pixel 60 after being flipped left and right (flipped left and right by itself) along the first direction X is the same as the arrangement structure of the adjacent pixel unit 00P in the same column. Furthermore, it can make the pixel arrangement in the second display area AA2 more compact, which is beneficial to reducing the distance between each sub-pixel directly, improving the PPI of the second display area AA2, and is beneficial to improving the display effect of the second display area AA2.

[0070] And the arrangement of the fourth sub-pixel 40, the fifth sub-pixel 50, and the sixth sub-pixel 60 in the second display area AA2 of this embodiment can avoid, in the second direction Y, two adjacent pixel units 00P in the same column (such as Figure 7Subpixels of the same color in pixel units 00P1 and 00P2 (e.g.) Figure 7 The fourth sub-pixel 40 of pixel unit 00P1 and the fourth sub-pixel 40 of pixel unit 00P2, or as... Figure 7 The fifth sub-pixel 50 of pixel unit 00P1 and the fifth sub-pixel 50 of pixel unit 00P2, or as... Figure 7 The sixth sub-pixel 60 of pixel unit 00P1 and the sixth sub-pixel 60 of pixel unit 00P2 are arranged in a straight line, and the vapor deposition openings on the vapor deposition mask used to form sub-pixels of the same color are also staggered, which can reduce the difficulty of vapor deposition mask manufacturing process and vapor deposition process.

[0071] Optional, such as Figure 5 and Figure 8 As shown, Figure 8 yes Figure 5 Another partially enlarged structural diagram of the second display area. In this embodiment, the display panel 000 of the second display area AA2 includes a plurality of fourth sub-pixels 40, a plurality of fifth sub-pixels 50, and a plurality of sixth sub-pixels 60; wherein the fifth sub-pixels 50 are located in the second display area AA2. Figure 8 The diagram shows the center position of the first dashed square J1 and the four corner positions of the first dashed square J1. The sixth sub-pixel 60 is located at the center position of the side of the first dashed square J1 in the second display area AA2. The fourth sub-pixel 40 is located at... Figure 8 The schematic diagram shows a second dashed square J2, which is formed by connecting two sixth sub-pixels 60 located at the center of two adjacent sides of the first dashed square J1, and a fifth sub-pixel 50 located at the center and a vertices of the first dashed square J1, respectively, adjacent to the two sixth sub-pixels 60. Four second dashed squares J2 can form one first dashed square J1. The arrangement structure of the fourth sub-pixel 40, fifth sub-pixel 50, and sixth sub-pixel 60 provided in this embodiment allows the fourth sub-pixel 40, fifth sub-pixel 50, and sixth sub-pixel 60 of the same pixel unit 0OP to be closely arranged. This maximizes the area of ​​a single sub-pixel while maintaining the minimum pixel spacing, thereby reducing the driving current of the display panel and increasing its lifespan.

[0072] Further optional, the above Figures 5-8The fourth sub-pixel 40 shown in the diagram can be a green sub-pixel, the fifth sub-pixel 50 can be a red sub-pixel, and the sixth sub-pixel 60 can be a blue sub-pixel. Since the luminous efficiency and lifespan of the blue organic light-emitting material used to make the blue sub-pixel are usually the lowest, the required light-emitting area is correspondingly larger. The luminous efficiency and lifespan of the green organic light-emitting material used to make the green sub-pixel are the next highest. Therefore, in this embodiment, the projected area of ​​the sixth sub-pixel 60 on the light-emitting surface of the display panel 000 can be larger than that of the fourth sub-pixel 40 on the light-emitting surface of the display panel 000, and the projected area of ​​the sixth sub-pixel 60 on the light-emitting surface of the display panel 000 can be larger than that of the fifth sub-pixel 50 on the light-emitting surface of the display panel 000. This is to compensate for the attenuation of the blue sub-pixel, and the projected area of ​​the fourth sub-pixel 40 on the light-emitting surface of the display panel 000 can be larger than that of the fifth sub-pixel 50 on the light-emitting surface of the display panel 000, in order to compensate for the attenuation of the green sub-pixel. This can improve the luminous efficiency and lifespan of the entire display panel 000, which is beneficial to ensuring the display quality of the second display area AA2 of the display panel 000.

[0073] It is understood that in this embodiment Figure 7 and Figure 8 This is merely an example drawing of the shape and size of each sub-pixel in the second display area AA2. In actual implementation, the shapes of the fourth sub-pixel 40, the fifth sub-pixel 50, and the sixth sub-pixel 60 are not limited to these dimensions. Figure 7 and Figure 8 The rectangle shown can also be any other quadrilateral besides a rectangle, or one or any combination of polygons such as triangles, pentagons, hexagons, and octagons. This embodiment does not limit this.

[0074] It should be noted that this embodiment is only an example to illustrate the arrangement structure of sub-pixels in the second display area AA2 of the display panel 000. In specific implementation, the pixel arrangement structure of the second display area AA2 of the display panel 000 includes, but is not limited to, this, and may also be other arrangement structures, which will not be elaborated here.

[0075] In some alternative embodiments, please continue to refer to the references. Figures 1-3 In this embodiment, in the first display area AA1 of the warrior panel 000, two adjacent pixel units 00 are mirror-symmetrical along the first direction X; and two adjacent pixel units 00 are mirror-symmetrical along the second direction Y.

[0076] This embodiment explains that the pixel arrangement in the first display area AA1 of the display panel 000 can be a structure in which two adjacent pixel units 00 are mirror-symmetrical in the first direction X, such as... Figure 2As shown, in a repeating unit Q, the sub-pixels of different colors in the first pixel unit 001 and the second pixel unit 002 of two adjacent pixel units 00 are mirror-symmetrical about the axis of symmetry M1. That is, the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the second pixel unit 002 are mirror-symmetrical about the axis of symmetry M1, the second sub-pixel 20 of the first pixel unit 001 and the second sub-pixel 20 of the second pixel unit 002 are mirror-symmetrical about the axis of symmetry M1, and the third sub-pixel 30 of the first pixel unit 001 and the third sub-pixel 30 of the second pixel unit 002 are mirror-symmetrical about the axis of symmetry M1. The pixels are mirror-symmetric; the sub-pixels of different colors in the third pixel unit 003 and the fourth pixel unit 004 of two adjacent pixel units 00 are mirror-symmetric about the axis of symmetry M1. That is, the first sub-pixel 10 of the third pixel unit 003 and the first sub-pixel 10 of the fourth pixel unit 004 are mirror-symmetric about the axis of symmetry M1, the second sub-pixel 20 of the third pixel unit 003 and the second sub-pixel 20 of the fourth pixel unit 004 are mirror-symmetric about the axis of symmetry M1, and the third sub-pixel 30 of the third pixel unit 003 and the third sub-pixel 30 of the fourth pixel unit 004 are mirror-symmetric about the axis of symmetry M1. Optionally, the pixel arrangement in the first display area AA1 of the display panel 000 can also be a structure in which two adjacent pixel units 00 are mirror-symmetric in the second direction Y, such as... Figure 2 As shown, in a repeating unit Q, the sub-pixels of different colors in the first pixel unit 001 and the third pixel unit 003 of two adjacent pixel units 00 are mirror-symmetrical about the axis of symmetry M2. That is, the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the third pixel unit 003 are mirror-symmetrical about the axis of symmetry M1, the second sub-pixel 20 of the first pixel unit 001 and the second sub-pixel 20 of the third pixel unit 003 are mirror-symmetrical about the axis of symmetry M2, and the third sub-pixel 30 of the first pixel unit 001 and the third sub-pixel 30 of the third pixel unit 003 are mirror-symmetrical about the axis of symmetry M2. 1. Mirror symmetry: The sub-pixels of different colors in the second pixel unit 002 and the fourth pixel unit 004 of two adjacent pixel units 00 are mirror symmetric about the axis of symmetry M2. That is, the first sub-pixel 10 of the second pixel unit 002 and the first sub-pixel 10 of the fourth pixel unit 004 are mirror symmetric about the axis of symmetry M1, the second sub-pixel 20 of the second pixel unit 002 and the second sub-pixel 20 of the fourth pixel unit 004 are mirror symmetric about the axis of symmetry M1, and the third sub-pixel 30 of the second pixel unit 002 and the third sub-pixel 30 of the fourth pixel unit 004 are mirror symmetric about the axis of symmetry M1. Optionally, adjacent pixel units 00 in different repeating units Q can also have a mirror symmetric structure in the first direction X, such as... Figure 2As shown, along the first direction X, the second pixel unit 002 in one repeating unit Q can be mirror-symmetric with the first pixel unit 001 in another repeating unit Q about the axis of symmetry M3. Optionally, two adjacent pixel units 00 in different repeating units Q can also have a mirror-symmetric structure in the second direction Y, such as... Figure 2 As shown, along the second direction Y, the third pixel unit 003 in one repeating unit Q can be mirror-symmetrical to the first pixel unit 001 in another repeating unit Q about the axis of symmetry M4. The pixel arrangement in this embodiment can increase the pixel density in the first display area AA1 while also allowing as many sub-pixels of the same color as possible to be clustered together. For example, the third sub-pixels 30 of two adjacent pixel units 00 in the first direction X can be close together, the second sub-pixels 20 of two adjacent pixel units 00 in the first direction X can be close together, the second sub-pixels 20 of two adjacent pixel units 00 in the second direction Y can be close together, and the third sub-pixels 30 of two adjacent pixel units 00 in the second direction Y can be close together. This allows sub-pixels of the same color in different pixel units 00 to share the same opening of a metal mask for vapor deposition, which helps to reduce the number of openings in the metal mask used in the process and avoids the metal mask from reducing its strength due to too many openings or too small openings, thereby improving the strength of the metal mask.

[0077] In some alternative embodiments, please continue to refer to the references. Figures 1-3 In this embodiment, in the first display area AA1 of the warrior panel 000, the shape of the first sub-pixel 10 projected onto the light-emitting surface of the display panel 000 is square.

[0078] In a repeating unit Q, the line connecting the geometric center points P1 of the four first sub-pixels 10 forms a square.

[0079] This embodiment explains that the pixel arrangement in the first display area AA1 of the display panel 000 can be such that when the shape of the first sub-pixel 10 projected onto the light-emitting surface of the display panel 000 is square, the line connecting the geometric center points P1 of the four first sub-pixels 10 in a repeating unit Q is square, that is, the four first sub-pixels 10 in a repeating unit Q can surround each other. Since the square first sub-pixel 10 includes a connected first side 10A and a second side 10B, and the first side 10A and the second side 10B have an intersection point O, this embodiment sets the second sub-pixel 20 to be on one side of the first side 10A and adjacent to the first sub-pixel 10, and the third sub-pixel 30 to be on one side of the second side 10B and adjacent to the first sub-pixel 10, that is, no other sub-pixels are set between the two adjacent sub-pixels, forming a structure in which the second sub-pixel 20 and the third sub-pixel 30 partially surround the first sub-pixel 10, thereby enabling more... When multiple pixel units 00 are arranged along the first direction X to form a pixel unit row 00H, sub-pixels of the same color in different pixel units 00 can be placed together, and there are no other sub-pixels of the same color in different pixel units 00 before them. When multiple pixel units 00 are arranged along the second direction Y to form a pixel unit column 00L, sub-pixels of the same color in different pixel units 00 can be placed together, and there are no other sub-pixels of the same color in different pixel units 00 before them. This allows sub-pixels of the same color in different pixel units 00 to share an opening of a metal mask for vapor deposition, which helps to reduce the number of openings in the metal mask used in the process. This avoids the metal mask from losing its strength due to too many openings or too small openings. In this way, the strength of the metal mask can be improved, and the pixel density of the first display area AA1 can also be increased, which helps to ensure the display quality of the first display area AA1.

[0080] In some alternative embodiments, please refer to the references. Figures 1-2 , Figure 9 and Figure 10 , Figure 9 yes Figure 2 Another structural diagram of a repeating unit. Figure 10 yes Figure 9 A cross-sectional structural diagram along line A-A'. In this embodiment, the display panel 000 also includes multiple pixel circuits 70. Optionally, each pixel circuit 70 corresponds to at least one sub-pixel.

[0081] In a repeating unit Q, among the four pixel units 00, at least two of the first sub-pixels 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 share a pixel circuit 70; and / or,

[0082] The second sub-pixel 20 of the first pixel unit 001 and the second sub-pixel 20 of the second pixel unit 002 share a pixel circuit 70; the second sub-pixel 20 of the third pixel unit 003 and the second sub-pixel 20 of the fourth pixel unit 004 share a pixel circuit 70; and / or,

[0083] The third sub-pixel 30 of the first pixel unit 001 and the third sub-pixel 30 of the third pixel unit 003 share a pixel circuit 70; the third sub-pixel 30 of the second pixel unit 002 and the third sub-pixel 30 of the fourth pixel unit 004 share a pixel circuit 70.

[0084] This embodiment explains that the film structure of the display panel 000 may include at least a substrate E1 (not filled in the figure), a driving circuit layer E2, an anode layer E3, a pixel definition layer E4, an organic light-emitting layer E5, a cathode layer E6, and a thin film encapsulation layer E7. The driving circuit layer E2 can be used to set multiple pixel circuits 70 of the display panel 000. Each pixel circuit 70 corresponds to at least one sub-pixel, that is, each pixel circuit 70 is electrically connected to at least one sub-pixel to provide a driving signal for at least one sub-pixel. The anode layer E3 can be formed into multiple anode blocks E31 through a patterning process. Each pixel circuit 70 may include multiple thin film transistors T. At least one thin film transistor T is used to be electrically connected to the anode block E31 of at least one sub-pixel to transmit the driving signal of the pixel circuit 70 to the anode block E31. Optionally, the anode layer E3 can be formed from various conductive materials. For example, the anode layer E3 can be formed as a transparent anode or a reflective anode depending on its intended use. When the anode block E31 is formed as a transparent anode, the material of the anode layer E3 may include indium tin oxide (ITO), indium zinc oxide (IZO), etc.; when the anode block E31 is formed as a reflective anode, the material of the anode layer E3 may include silver, magnesium, aluminum, or other metal mixtures, and this embodiment does not specifically limit this. The pixel definition layer E4 includes multiple openings E4K, and the organic light-emitting layer E5 includes multiple light-emitting parts E51. The orthographic projection of the openings E4K onto the substrate E1 overlaps with the orthographic projection of the anode block E31 onto the substrate E1. The openings E4K expose at least a portion of the anode block E31 of the anode layer E3. The light-emitting parts E51 are formed within the openings E4K. The pixel definition layer E4 is used to prevent color mixing or cross-coloring between two adjacent light-emitting parts E51. That is, the openings E4K of the pixel definition layer E4 are used to define the light-emitting parts E51 of adjacent organic light-emitting materials, so as to separate the light-emitting parts E51 of different colors into relatively independent structures. A sub-pixel of the display panel 000 can be correspondingly configured with a light-emitting element E51. The cathode layer E6 on the light-emitting layer E5 allows the light-emitting element E51 to be stacked with the anode block E31 and the cathode layer E6. By applying a voltage between the anode block E31 and the cathode layer E6, the light-emitting element E51 emits visible light, thereby realizing an image that can be recognized by the user. A thin-film encapsulation layer E7 can also be disposed on the side of the cathode layer E6 away from the substrate E1. The thin-film encapsulation layer E7 can be used to isolate water and oxygen, preventing water vapor and oxygen in the air from entering the organic light-emitting layer E5 and the driving circuit layer E2, thereby damaging the components therein. The display panel 000 may also include other film layer structures, such as a planarization layer, etc., which will not be described in detail in this embodiment. For specific understanding, please refer to the structure of organic light-emitting display panels in related technologies.Optionally, the thin film encapsulation layer E7 in this embodiment may include a multilayer stacked structure of inorganic layer, organic layer and inorganic layer, which can further reduce the probability of water and oxygen intrusion.

[0085] like Figure 9 and Figure 10 As shown, in the first display area AA1 of the display panel 000 provided in this embodiment, since the four first sub-pixels 10 of the four pixel units 00 in one repeating unit Q are close together, it can be configured that in the four pixel units 00 of one repeating unit Q, at least two first sub-pixels 10 of the first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 share one pixel circuit 70. For example, the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the second pixel unit 002 can share one pixel circuit 70, or the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the third pixel unit 003 can share one pixel circuit 70. Alternatively, the first sub-pixel 10 of the second pixel unit 002 and the first sub-pixel 10 of the fourth pixel unit 004 can share a pixel circuit 70, or the first sub-pixel 10 of the third pixel unit 003 and the first sub-pixel 10 of the fourth pixel unit 004 can share a pixel circuit 70. Furthermore, the four first sub-pixels 10 of three or four pixel units 00 can share a pixel circuit 70. This helps reduce the number of pixel circuits 70 set in the driving circuit layer E2 of the display panel 000, saving the layout space of the driving circuit layer E2, avoiding short circuits caused by excessively dense wiring in the driving circuit layer E2, and also helps reduce the area occupied by the pixel circuits 70 in the driving circuit layer E2, thereby increasing the effective display area of ​​the display panel 000, i.e., increasing the opening area of ​​each sub-pixel to improve display efficiency.

[0086] It is understandable that, in the four pixel units 00 of a repeating unit Q, at least two of the first sub-pixels 10 of the first pixel unit 001, the second pixel unit 002, the third pixel unit 003, and the fourth pixel unit 004 share a pixel circuit 70. Therefore, the corresponding anode blocks E31 of these at least two first sub-pixels 10 can be connected into a single structure, such as... Figure 9As shown, when the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the second pixel unit 002 share a pixel circuit 70, the anode block E31 corresponding to the first sub-pixel 10 of the first pixel unit 001 and the anode block E31 corresponding to the first sub-pixel 10 of the second pixel unit 002 can be connected into a single structure, and the first sub-pixel 10 of the first pixel unit 001 and the first sub-pixel 10 of the second pixel unit 002 correspond to only one pixel circuit 70. Figure 9 The block diagram illustrates a pixel circuit 70. In actual implementation, the structure of the pixel circuit 70 is not limited to this. Figure 10 In the diagram, a thin-film transistor T is used to represent a pixel circuit 70. The anode block E31 corresponding to the first sub-pixel 10 of the first pixel unit 001 and the anode block E31 corresponding to the first sub-pixel 10 of the second pixel unit 002 are connected to form a single structure and electrically connected to the same thin-film transistor T. The light-emitting part E51 corresponding to the first sub-pixel 10 of the first pixel unit 001 and the light-emitting part E51 corresponding to the first sub-pixel 10 of the second pixel unit 002 can be separated by the non-opening structure of the pixel definition layer E4 to achieve the driving display effect of different pixel units 00.

[0087] It is understood that this embodiment is only used as an example to illustrate how two first sub-pixels 10 of the first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 in a repeating unit Q share a pixel circuit 70. In specific implementation, when three or four first sub-pixels 10 of the first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 in a repeating unit Q share a pixel circuit 70, the following can be referred to... Figure 10 The schematic film structure can be understood as follows, the only difference being that the anode blocks E31 corresponding to the three first sub-pixels 10 are connected into a whole, or the anode blocks E31 corresponding to the four first sub-pixels 10 are connected into a whole. This embodiment will not be described in detail here.

[0088] Optional, such as Figure 9 and Figure 11 As shown, Figure 11 yes Figure 9A cross-sectional structural diagram along line B-B' is provided in this embodiment. In the first display area AA1 of the display panel 000, since the two second sub-pixels 20 of two pixel units 00 are close together in a repeating unit Q, it can be set that in a repeating unit Q, the second sub-pixels 20 of the first pixel unit 001 and the second sub-pixels 20 of the second pixel unit 002 share a pixel circuit 70; the second sub-pixels 20 of the third pixel unit 003 and the second sub-pixels 20 of the fourth pixel unit 004 share a pixel circuit 70. That is, the anode block E31 corresponding to the second sub-pixel 20 of the first pixel unit 001 and the anode block E31 corresponding to the second sub-pixel 20 of the second pixel unit 002 are connected to form a single structure and electrically connected to the same thin-film transistor T. The light-emitting part E51 corresponding to the second sub-pixel 20 of the first pixel unit 001 and the light-emitting part E51 corresponding to the second sub-pixel 20 of the second pixel unit 002 can be separated by the non-opening structure of the pixel definition layer E4; the anode block E31 corresponding to the second sub-pixel 20 of the third pixel unit 003 and the anode block E31 corresponding to the second sub-pixel 20 of the fourth pixel unit 004 are connected to form a single structure and electrically connected to the same thin-film transistor T. The light-emitting part E51 corresponding to the second sub-pixel 20 of 03 and the light-emitting part E51 corresponding to the second sub-pixel 20 of the fourth pixel unit 004 can be separated by the non-opening structure of the pixel definition layer E4 to achieve the driving display effect of different pixel units 00. At the same time, it is also beneficial to further reduce the number of pixel circuits 70 set in the driving circuit layer E2 in the display panel 000, save the layout space of the driving circuit layer E2, avoid short circuits caused by excessive wiring in the driving circuit layer E2, and also help to reduce the area occupied by the pixel circuits 70 in the driving circuit layer E2, thereby increasing the effective display area of ​​the display panel 000, that is, it is beneficial to increase the opening area of ​​each sub-pixel to improve display efficiency.

[0089] Optional, such as Figure 9 and Figure 12 As shown, Figure 12 yes Figure 9A cross-sectional structural diagram along the C-C' direction shows that, since the two third sub-pixels 30 of two pixel units 00 are close together in a repeating unit Q, the third sub-pixels 30 of the first pixel unit 001 and the third sub-pixels 30 of the third pixel unit 003 can share a pixel circuit 70; the third sub-pixels 30 of the second pixel unit 002 and the third sub-pixels 30 of the fourth pixel unit 004 can share a pixel circuit 70. That is, the anode block E31 corresponding to the third sub-pixel 30 of the first pixel unit 001 and the anode block E31 corresponding to the third sub-pixel 30 of the third pixel unit 003 are connected into a single structure and electrically connected to the same thin-film transistor T. The light-emitting part E51 corresponding to the third sub-pixel 30 of the first pixel unit 001 and the light-emitting part E51 corresponding to the third sub-pixel 30 of the third pixel unit 003 can be separated by the non-opening structure of the pixel definition layer E4; the anode block E31 corresponding to the third sub-pixel 30 of the second pixel unit 002 and the anode block E31 corresponding to the third sub-pixel 30 of the fourth pixel unit 004 are connected into a single structure and electrically connected to the same thin-film transistor T. The light-emitting part E51 corresponding to the third sub-pixel 30 of 02 and the light-emitting part E51 corresponding to the third sub-pixel 30 of the fourth pixel unit 004 can be separated by the non-opening structure of the pixel definition layer E4 to achieve the driving display effect of different pixel units 00. At the same time, it is also beneficial to further reduce the number of pixel circuits 70 set in the driving circuit layer E2 in the display panel 000, save the layout space of the driving circuit layer E2, avoid short circuits caused by excessive wiring in the driving circuit layer E2, and also reduce the area occupied by the pixel circuits 70 in the driving circuit layer E2, thereby increasing the effective display area of ​​the display panel 000, that is, it is beneficial to increase the opening area of ​​each sub-pixel to improve display efficiency.

[0090] In some alternative embodiments, please refer to the references. Figure 1 , Figure 13 , Figure 14 , Figure 15 and Figure 16 , Figure 13 yes Figure 1 Another enlarged view of the first display area in the middle.

Figure 15 yes Figure 13 Schematic diagram of the cross-sectional structure along the G-G' direction. Figure 16 yes Figure 13 A cross-sectional structural diagram along the H-H' direction. In this embodiment, the four first sub-pixels 10 of a repeating unit Q in the first display area AA1 of the display panel 000 share a pixel circuit 70.

[0091] Along the first direction X, two adjacent repeating units Q (e.g.)Figure 13 In the illustrated repeating units Q1 and Q2, four adjacent third sub-pixels 30 share a single pixel circuit 70.

[0092] Along the second direction Y, two adjacent repeating units Q (e.g.) Figure 13 In the illustrated repeating units Q1 and Q3, four adjacent second sub-pixels 20 share a single pixel circuit 70.

[0093] This embodiment explains the pixel arrangement structure of the first display area AA1 of the display panel 000, which is used to increase pixel density, such as... Figure 13 and Figure 14 As shown, since the four first sub-pixels 10 of the four pixel units 00 in a repeating unit Q are close together, the four first sub-pixels 10 of a repeating unit Q can be configured to share a pixel circuit 70. That is, in the four pixel units 00 of a repeating unit Q, the anode blocks E31 corresponding to the first sub-pixels 10 of the first pixel unit 001, the second pixel unit 002, the third pixel unit 003, and the fourth pixel unit 004 can be connected into a larger integral structure, such as... Figure 13 As shown, when the first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 share a single pixel circuit 70, the anode block E31 corresponding to the first sub-pixel 10 of the first pixel unit 001, the anode block E31 corresponding to the first sub-pixel 10 of the second pixel unit 002, the anode block E31 corresponding to the first sub-pixel 10 of the third pixel unit 003, and the anode block E31 corresponding to the first sub-pixel 10 of the fourth pixel unit 004 can be formed into a large-area monolithic structure. The first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 correspond to only one pixel circuit 70. Figure 13 The block diagram illustrates a pixel circuit 70. In actual implementation, the structure of the pixel circuit 70 is not limited to this. Figure 14 In the diagram, a thin-film transistor T is used to represent a pixel circuit 70. The anode block E31 corresponding to the first sub-pixel 10 of the first pixel unit 001, the anode block E31 corresponding to the first sub-pixel 10 of the second pixel unit 002, the anode block E31 corresponding to the first sub-pixel 10 of the third pixel unit 003, and the anode block E31 corresponding to the first sub-pixel 10 of the fourth pixel unit 004 are connected into a large-area monolithic structure and electrically connected to the same thin-film transistor T. Optionally, such as... Figure 13 and Figure 14As shown, the pixel circuit 70 includes at least one thin-film transistor T. The display panel 000 of the first display area AA1 includes multiple first anodes E30. The orthographic projection of one first anode E30 onto the light-emitting surface of the display panel 000 overlaps with the four first sub-pixels 10 of a repeating unit Q. The thin-film transistor T is electrically connected to the first anodes E30. The light-emitting parts E51 corresponding to the first sub-pixel 10 of the first pixel unit 001, the first sub-pixel 10 of the second pixel unit 002, the first sub-pixel 10 of the third pixel unit 003, and the first sub-pixel 10 of the fourth pixel unit 004 can be separated by the non-opening structure of the pixel definition layer E4 to achieve the driving display effect of different pixel units 00.

[0094] like Figure 13 , Figure 15 and Figure 16 As shown, in the pixel arrangement structure of the first display area AA1 of the display panel 000 in this embodiment, which is used to increase pixel density, since along the first direction X, two adjacent repeating units Q (such as...) Figure 13 In the illustrated repeating units Q1 and Q2, four adjacent third sub-pixels 30 are close together, so it is possible to set four adjacent third sub-pixels 30 of two adjacent repeating units Q to share a pixel circuit 70; along the second direction Y, two adjacent repeating units Q (such as Figure 13 In the illustrated repeating units Q1 and Q3, four adjacent second sub-pixels 20 are placed together. Therefore, four adjacent second sub-pixels 20 of two adjacent repeating units Q can be set to share a pixel circuit 70. This can further reduce the number of pixel circuits 70 set in the driving circuit layer E2 of the display panel 000, save the layout space of the driving circuit layer E2, avoid short circuits caused by excessive wiring in the driving circuit layer E2, and better reduce the area occupied by the pixel circuits 70 in the driving circuit layer E2, thereby increasing the effective display area of ​​the display panel 000, which is conducive to increasing the opening area of ​​each sub-pixel and improving display efficiency.

[0095] In some alternative embodiments, please refer to the references. Figure 1 , Figure 17 and Figure 18 , Figure 17 yes Figure 1 Another enlarged view of the first display area in the middle. Figure 18 yes Figure 17 A schematic diagram of a repeating unit is shown in this embodiment. The orthographic projection of the second sub-pixel 20 of the display panel 000 onto the light-emitting surface of the display panel 000 includes at least one arc-shaped edge; and / or, the orthographic projection of the third sub-pixel 30 onto the light-emitting surface of the display panel 000 includes at least one arc-shaped edge.

[0096] Optionally, in the four pixel units 00 of a repeating unit Q, along the first direction X, the arcuate edge 20A1 of the second sub-pixel 20 of the first pixel unit 001 is located on the side of the second sub-pixel 20 of the first pixel unit 001 away from the second pixel unit 002; the arcuate edge 20A2 of the second sub-pixel 20 of the second pixel unit 002 is located on the side of the second sub-pixel 20 of the second pixel unit 002 away from the first pixel unit 001; and / or,

[0097] In a repeating unit Q, among the four pixel units 00, along the second direction Y, the arc edge 30A1 of the third sub-pixel 30 of the first pixel unit 001 is located on the side of the third sub-pixel 30 of the first pixel unit 001 that is away from the third pixel unit 003; the arc edge 30A3 of the third sub-pixel 30 of the third pixel unit 003 is located on the side of the third sub-pixel 30 of the third pixel unit 003 that is away from the first pixel unit 001.

[0098] This embodiment explains that the orthographic projection of the second sub-pixel 20 of the display panel 000 onto the light-emitting surface of the display panel 000 includes at least one curved edge, such as the curved edge 20A1 of the second sub-pixel 20 in the first pixel unit 001, the curved edge 20A2 of the second sub-pixel 20 in the second pixel unit 002, the curved edge 20A3 of the second sub-pixel 20 in the third pixel unit 003, and the curved edge 20A4 of the second sub-pixel 20 in the fourth pixel unit 004 in a repeating unit Q; and / or, the orthographic projection of the third sub-pixel 30 onto the light-emitting surface of the display panel 000 includes at least one curved edge, such as the curved edge 20A1 of the second sub-pixel 20 in the first pixel unit 001 onto the light-emitting surface of the display panel 000 in a repeating unit Q. The curved edge 30A1, the curved edge 30A2 of the third sub-pixel 30 in the second pixel unit 002, the curved edge 30A3 of the third sub-pixel 30 in the third pixel unit 003, and the curved edge 20A4 of the third sub-pixel 30 in the fourth pixel unit 004, allow the edges of the second sub-pixel 20 and / or the third sub-pixel 30 away from the first sub-pixel 10 in a pixel unit 00 to be curved edges as much as possible. This makes the light-transmitting area 01 enclosed by the four repeating units Q as circular or a relatively rounded shape such as a square with rounded corners as possible. Optionally, the orthographic projection shape of the light-transmitting area 01 on the light-emitting surface of the display panel 000 includes any one of a circle, an ellipse, or a rounded quadrilateral. Since the diffraction of light is related to the shape of the light-transmitting area 01, a relatively rounded shape such as a circle or a square with rounded corners can be equivalent to a polygon composed of many line segments, such as... Figure 19 As shown, Figure 19 Yes Figure 2 This diagram illustrates the simulation results of diffraction when the light-transmitting area in the first display area is circular. The horizontal axis represents the viewing angle, and the vertical axis represents the diffraction intensity. Figure 19The simulation results show that when viewing the display panel 000 from different angles indicated by the horizontal axis, the diffraction intensity indicated by the vertical axis is not significantly different, and there are no particularly strong diffraction peaks. That is, the diffraction intensity is relatively average at each viewing angle. Therefore, in this embodiment, the edge of the second sub-pixel 20 and / or the third sub-pixel 30 away from the first sub-pixel 10 in a pixel unit 00 is set to be as round as possible, so that the light-transmitting area 01 enclosed by the four repeating units Q is as round as possible or a relatively rounded shape such as a square with rounded corners. This can reduce the diffraction of the first display area AA1 and help to further improve the display quality.

[0099] It is understood that in this embodiment Figure 17 This example illustrates the concept of an elliptical shape as the orthographic projection of the light-transmitting area 01 onto the light-emitting surface of the display panel 000. In practice, the shape of the light-transmitting area 01 is not limited to this and can also be other relatively rounded shapes. This embodiment will not elaborate on these points.

[0100] In some alternative embodiments, please refer to the references. Figure 1 , Figure 17 , Figure 18 and Figure 20 , Figure 20 yes Figure 1 Another partially enlarged structural schematic diagram of the first display area. The display panel 000 provided in this embodiment includes a signal line 80, and the signal line 80 includes an arc segment 80A. The arc segment 80A is not located in the light-transmitting area 01; the arc segment 80A is arranged around the edge of the light-transmitting area 01.

[0101] This embodiment explains that the display panel 000 may include multiple signal lines 80. Optionally, the signal lines 80 may be made of a metal conductive film layer in the display panel 000, or they may be made of a transparent conductive film layer in the display panel 000. The signal lines 80 may be one or more of the following: scan lines, data lines, power signal lines, reference voltage signal lines, etc. When the signal lines 80 are made of a metal conductive film layer in the display panel 000, since the signal lines 80 generally have a relatively long extension length in the display panel 000, they will inevitably extend into the area where the light-transmitting area 01 is located. Therefore, in this embodiment, the signal lines 80 are configured to include an arc segment 80A. That is, when the signal lines 80 extend to the periphery of the light-transmitting area 01, the arc segment 80A is instead set around the edge of the light-transmitting area 01, so that the arc segment 80A is not located in the light-transmitting area 01. This helps to ensure the amount of light transmitted into the light-transmitting area 01 of the display panel 000, and thus helps to improve the imaging effect when the light-transmitting area 01 is used as a camera setting area.

[0102] It is understood that in this embodiment Figure 20This example illustrates that the signal line 80 can be a trace extending along the first direction X or the second direction Y. In actual implementation, the trace direction of the signal line 80 can also be other directions, which are not limited in this embodiment.

[0103] In some alternative embodiments, please refer to the references. Figures 1-3 and Figure 21 , Figure 21 This is a schematic diagram of the structure of a metal mask used in the manufacturing of the display panel of this embodiment. In this embodiment, during the manufacturing process of the display panel 000, a first metal mask S1 can be used. In the four pixel units 00 of a repeating unit Q, the pattern formed by the arrangement of four first sub-pixels 10 is formed through a first mask pattern opening S1K.

[0104] This embodiment explains that in the manufacturing process of a display panel 000 using organic light-emitting diode (OLED) display technology, the film deposition technology for organic light-emitting materials mainly relies on vacuum evaporation. During evaporation, a high-precision fine metal mask (FMM) is used to limit the evaporation areas of different colored light-emitting materials. A significant factor limiting pixel density improvement in the manufacturing process is the limitation on the size of the fine mask openings and the spacing between them, as well as the difficulty of mesh fabrication. Due to limitations in the high-precision metal mask manufacturing process, there are minimum values ​​for both the opening size and the distance between them. Since in existing technologies, one mask opening corresponds to one sub-pixel, the size of the sub-pixels cannot be made smaller, thus hindering the improvement of pixel density. The high-precision metal mask used in this embodiment includes a first metal mask S1. Due to the sub-pixel arrangement of the first display area AA1 provided in this embodiment, four first sub-pixels 10 of the same color in a repeating unit Q can be placed close together. Therefore, the pattern formed by the arrangement of the four first sub-pixels 10 in the four pixel units 00 of a repeating unit Q can be formed through the same first mask pattern opening S1K of the first metal mask S1. This reduces the number of openings in the first metal mask S1 used in the process, avoiding a decrease in the strength of the first metal mask S1 due to too many openings or too small size. This improves the strength of the first metal mask S1 while achieving a high pixel density pixel arrangement structure with fewer openings, thus improving the display quality of the resulting display panel 000. Therefore, the display panel provided in this embodiment can effectively improve the resolution and display effect of the display panel 000 under existing process conditions without increasing the manufacturing difficulty of the metal mask.

[0105] Optional, please refer to the reference. Figures 1-3 and Figure 22 , Figure 23 ,Figure 22 This is a schematic diagram of another type of metal mask used in manufacturing the display panel of this embodiment. Figure 23 This is a schematic diagram of another metal mask used in the manufacturing of the display panel of this embodiment. In this embodiment, another second metal mask S2 can be used in the manufacturing process of the display panel 000. In this embodiment, four third sub-pixels 30 of the same color that are close together in two adjacent repeating units Q are formed by vapor deposition through an opening of a second metal mask S2. That is, in the first display area AA1, along the first direction X, the pattern formed by the arrangement of four third sub-pixels 30 of two adjacent repeating units Q is formed through a second mask pattern opening S2K. Four adjacent second sub-pixels 20 of the same color in two adjacent repeating units Q are deposited together through an opening in a third metal mask S3. That is, in the first display area AA1, along the second direction Y, the pattern formed by the four second sub-pixels 20 of two adjacent repeating units Q is formed through an opening in a third mask pattern S3K. This further reduces the number of openings in the second and third metal masks S2 and S3 used in the manufacturing process, avoiding a decrease in their strength due to excessive openings or small sizes. This improves the strength of the second and third metal masks S2 and S3 while achieving a high pixel density pixel arrangement structure with fewer openings, thus enhancing the display quality of the resulting display panel 000. Therefore, the display panel provided in this embodiment can effectively improve the resolution and display effect of the display panel 000 without increasing the manufacturing difficulty of the metal mask under existing process conditions.

[0106] In some alternative embodiments, please continue to refer to the references. Figures 1-3 In this embodiment, the light-transmitting area 01 of the display panel 000 may include either a white sub-pixel material or a transparent material. That is, the light-transmitting area 01 of the display panel 000 may be perforated and filled with transparent material, or the sub-pixels of the light-transmitting area 01 may be white sub-pixels. This helps to ensure the light transmittance of the light-transmitting area 01 and increase the amount of light transmitted through the light-transmitting area 01 of the display panel 000. When the first display area AA1 is used as a setting area for photosensitive devices such as cameras, it helps to ensure the light-sensing effect and improve the image quality.

[0107] In some alternative embodiments, please refer to Figure 24 , Figure 24 This is a schematic diagram of the planar structure of the display device provided in an embodiment of the present invention (to clearly illustrate the placement position of the photosensitive element W in this embodiment). Figure 24(Transparency filling has been performed). The display device 111 provided in this embodiment includes the display panel 000 provided in the above embodiments of the present invention. Optionally, the display device 111 may include a photosensitive element W and the display panel 000 provided in the above embodiments. The photosensitive element W is located in the first display area AA1 and may be disposed on the backlight side of the display panel 000. Optionally, the display device 111 may also be a transparent display device. Figure 24 The embodiments described herein use only a mobile phone as an example to illustrate the display device 111. It is understood that the display device 111 provided in the embodiments of the present invention can be other display devices 111 with display functions, such as computers, televisions, and in-vehicle display devices. The present invention does not impose specific limitations on these. The display device 111 provided in the embodiments of the present invention has the beneficial effects of the display panel 000 provided in the embodiments of the present invention. For details, please refer to the specific descriptions of the display panel 000 in the above embodiments. These descriptions will not be repeated here.

[0108] As can be seen from the above embodiments, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0109] The sub-pixel arrangement in the first display area of ​​the display panel provided by this invention not only ensures a sufficiently large light-transmitting area, improving the light transmittance of the first display area, but also allows each repeating unit in the first display area to include four pixel units, resulting in higher pixel density and better display quality. This not only further enhances display quality but also ensures image quality when the first display area is used as a camera area. Because the sub-pixel arrangement in the first display area provided by this invention allows four adjacent first sub-pixels of the same color to share an opening in a metal mask for vapor deposition within a repeating unit, two adjacent second sub-pixels of the same color to share an opening in a metal mask for vapor deposition, and two adjacent third sub-pixels of the same color to share an opening in a metal mask for vapor deposition, this not only reduces the number of openings in the metal mask used in the manufacturing process, preventing the metal mask from becoming weak due to excessive number and small size of openings, thus improving the strength of the metal mask, but also achieves a high pixel density pixel arrangement structure with fewer openings, improving the display quality of the resulting display panel.
