Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to pixel arrangement structures, display panels, and display devices. Background Technology

[0002] Organic light-emitting diode (OLED) display technology is considered the most promising next-generation display technology. Compared with liquid crystal display technology, OLED display technology has advantages such as low energy consumption, low cost, self-emissiveness, wide viewing angle, and fast response speed.

[0003] In the traditional OLED display panel manufacturing process, a fine metal mask (FMM) is typically used to pattern the light-emitting pixels. FMM technology is mature and has extensive mass production experience. However, FMM technology also suffers from limitations in precision and high cost. Fine metal mask-less technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance characteristics, offering advantages such as high performance, full-size display, and agile delivery.

[0004] However, the display effect of the pixel arrangement structure of the aforementioned display panel needs to be improved. Summary of the Invention

Detailed Implementation

[0110] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0111] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0112] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. It should be noted that, unless otherwise specified, different features in the embodiments of this application can be combined with each other.

[0113] For certain elements, terms like "above" or "over" are sometimes used when describing the position of an element located in a third direction, while "below" or "under" is used when describing the position of an element located in the opposite direction. Furthermore, when using terms like "above," "over," "below," "under," or "relative" to define the positional relationship between two elements, this includes not only the state where the two elements are directly adjacent but also the state where they are separated by gaps or other elements. Additionally, the terms "first," "second," and "third," etc., are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0114] In the process of developing this application, the inventors discovered the following problem in the related technology: the pixel arrangement structure includes multiple pixel units, and the pixel unit includes red sub-pixels, green sub-pixels and blue sub-pixels arranged sequentially along the row direction, and the multiple pixel units are arranged in an array along the row direction and column direction.

[0115] However, red subpixels near the edge of the pixel unit can cause a red border at the edge of the pixel unit, thus affecting the display effect of the pixel arrangement structure.

[0116] In view of at least one of the above problems, embodiments of this application provide a pixel arrangement structure, a display panel, and a display device, which can improve the display effect of the pixel arrangement structure.

[0117] The following will combine Figures 1-25The pixel arrangement structure, display panel, and display device provided in the embodiments of this application will be described.

[0118] See Figure 1 and Figure 3 This application provides a pixel arrangement structure 103, which includes a plurality of pixel units PX. Each pixel unit PX includes a first sub-pixel SPX1, which encloses at least one first receiving slot 161. For example, the number of first receiving slots 161 formed by the first sub-pixels SPX1 can be any number of 1, 2, 3, or more than 3. Each pixel unit PX also includes at least one second sub-pixel SPX2, which is correspondingly disposed with the at least one first receiving slot 161, and encloses a second receiving slot 162. In the corresponding second sub-pixel SPX2 and first receiving slot 161, the second sub-pixel SPX2 is located in the first receiving slot 161, and the opening of the first receiving slot 161 faces away from the opening of the second receiving slot 162. Pixel unit PX also includes at least one third sub-pixel SPX3, which is correspondingly disposed with at least one second sub-pixel SPX2. The third sub-pixel SPX3 is located in the second receiving slot 162 of the corresponding second sub-pixel SPX2. Thus, by setting the opening of the first receiving slot 161 opposite to the opening of the second receiving slot 162, the first sub-pixel SPX1 and the second sub-pixel SPX2 can wrap the third sub-pixel SPX3 in the middle of pixel unit PX, so that the edge of pixel unit PX is not provided with the third sub-pixel SPX3. That is, the third sub-pixel SPX3 avoids the edge position of pixel unit PX, thereby alleviating the problem of color fringing at the edge of pixel unit PX caused by the third sub-pixel SPX3, and thus improving the display effect of pixel arrangement structure 103. In addition, the second sub-pixel SPX2 wrapping the third sub-pixel SPX3, and the first sub-pixel SPX1 wrapping the second sub-pixel SPX2, helps to increase the white light synthesis area of ​​pixel unit PX, further reducing the color fringing problem. Secondly, by setting the opening of the first receiving groove 161 to face away from the opening of the second receiving groove 162, the first sub-pixel SPX1 and the second sub-pixel SPX2 are interlocked. This helps to prevent the uneven stress distribution of the film layer in the corresponding area caused by the openings of the first receiving groove 161 and the second receiving groove 162 being concentrated on the same side. This helps to improve the stress distribution uniformity of the corresponding packaging part, thereby improving the packaging reliability.

[0119] In this embodiment, the correspondence between A and B can refer to one A corresponding to at least one B, or one B corresponding to at least one A. For example, the correspondence between the second sub-pixel SPX2 and the first receiving slot 161 can refer to one second sub-pixel SPX2 corresponding to at least one first receiving slot 161, or one first receiving slot 161 corresponding to at least one second sub-pixel SPX2. This embodiment uses the example of one second sub-pixel SPX2 corresponding to one first receiving slot 161 for illustration.

[0120] In some embodiments, in the corresponding second sub-pixel SPX2 and the first receiving groove 161, the opening of the first receiving groove 161 and the opening of the second receiving groove 162 are respectively oriented towards the two sides of the second direction Y, that is, the opening of the first receiving groove 161 is oriented towards the opposite side of the opening of the second receiving groove 162 along the second direction Y.

[0121] In some embodiments, see Figure 1 The shape of the second sub-pixel SPX2 is U-shaped, thus the shape of the second sub-pixel SPX2 is relatively simple.

[0122] In some embodiments, see Figure 1 The third sub-pixel SPX3 is strip-shaped and extends along the second direction Y. Thus, the third sub-pixel SPX3 is long and strip-shaped, and its shape is relatively simple.

[0123] In some embodiments, see Figure 1 In the third sub-pixel SPX3 and the corresponding first receiving slot 161, the center of the first receiving slot 161 is located in the third sub-pixel SPX3. In this way, the third sub-pixel SPX3 is set close to the center of the corresponding first receiving slot 161, which helps to improve the distribution uniformity of each third sub-pixel SPX3 and improve the display uniformity.

[0124] In some embodiments, see Figure 2 In the same first sub-pixel SPX1, the first sub-pixel SPX1 includes a first extension segment 171 and at least two second extension segments 172. Two adjacent second extension segments 172 are connected at the same end along the second direction Y through a first extension segment 171. Two adjacent second extension segments 172 and the first extension segment 171 located between the two adjacent second extension segments 172 together form a first receiving groove 161.

[0125] In some embodiments, the first extension 171 extends along a first direction X.

[0126] In some embodiments, the second extension 172 extends along the second direction Y.

[0127] In some embodiments, the dimension of the second extension segment 172 along the second direction Y is greater than or equal to the dimension of the first extension segment 171 along the first direction X. This allows the extension length of the second extension segment 172 to be larger, which is beneficial to increasing the white light synthesis area of ​​the adjacent second extension segment 172, fourth extension segment 174 and third sub-pixel SPX3.

[0128] In some embodiments, see Figure 2 The dimension of the second extension segment 172 along the second direction Y is larger than the dimension of the second sub-pixel SPX2 along the second direction Y. This allows the second sub-pixel SPX2 to be completely accommodated in the first receiving slot 161, resulting in a larger overlap dimension of the second sub-pixel SPX2 and the second extension segment 142 along the first direction X. This is beneficial for increasing the white light combining area of ​​the adjacent second extension segment 172, fourth extension segment 174 and third sub-pixel SPX3.

[0129] In some embodiments, the first sub-pixel SPX1 is a blue sub-pixel. Thus, in pixel unit PX, the blue sub-pixel is positioned outside the second sub-pixel SPX2 and the third sub-pixel SPX3, which helps to increase the area of ​​the blue sub-pixel and extend its lifespan. However, in OLED display panels, the lifespan of blue sub-pixels is shorter than that of sub-pixels of other colors.

[0130] In some embodiments, the second sub-pixel SPX2 is a green sub-pixel.

[0131] In some embodiments, the third sub-pixel SPX3 is a red sub-pixel. This allows the red sub-pixel to surround the middle of the pixel unit PX, eliminating the presence of red sub-pixels at the edges of the pixel unit PX. This mitigates the problem of red borders at the edges of the pixel unit PX caused by red sub-pixels, thereby improving the display effect of the pixel arrangement structure 103. Furthermore, the human eye is more sensitive to red borders than other colors; improving the red border can better alleviate the adverse effects of borders on the display effect of the pixel arrangement structure 103.

[0132] In some embodiments, see Figure 1 Along the second direction Y, the size of the third sub-pixel SPX3, the size of the second sub-pixel SPX2, and the size of the first sub-pixel SPX1 increase sequentially. This allows the third sub-pixel SPX3 to be well enclosed by the second sub-pixel SPX2, and the second sub-pixel SPX2 to be well enclosed by the first sub-pixel SPX1. It also results in a larger overlap size of the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3 along the first direction X, which is beneficial for increasing the white light synthesis area of ​​the pixel unit PX.

[0133] In some embodiments, see Figure 2In the corresponding second sub-pixel SPX2 and third sub-pixel SPX3, the second sub-pixel SPX2 includes a third extension segment 173 and two fourth extension segments 174. The third extension segment 173 is connected to the same end of the two fourth extension segments 174 along the second direction Y. The third extension segment 173 and the two fourth extension segments 174 together form a second receiving groove 162. The third extension segment 173 and the two fourth extension segments 174 are respectively located on the three sides of the third sub-pixel SPX3.

[0134] In some embodiments, in the corresponding second sub-pixel SPX2 and third sub-pixel SPX3, two fourth extension segments 174 are located on both sides of the third sub-pixel SPX3 along the first direction X, and the third extension segment 173 is located on one side of the third sub-pixel SPX3 along the second direction Y. In the corresponding second sub-pixel SPX2 and the first sub-pixel SPX1 at the first receiving groove 161, one second extension segment 172 is located on the side of a fourth extension segment 174 away from the center of the second sub-pixel SPX2, and another second extension segment 172 is located on the side of another fourth extension segment 174 away from the center of the second sub-pixel SPX2. The first extension segment 171 is located on the side of the opening of the second receiving groove 162 away from the center of the second sub-pixel SPX2. In this way, the opening of the first receiving groove 161 is oriented opposite to the opening of the corresponding second receiving groove 162. The first sub-pixel SPX1 and the second sub-pixel SPX2 can wrap the third sub-pixel SPX3 in the middle of the pixel unit PX, thereby improving the color edge problem. It also helps to prevent the uneven stress distribution of the film layer in the corresponding area caused by the openings of the first receiving groove 161 and the second receiving groove 162 being concentrated on the same side, thereby improving the stress distribution uniformity of the corresponding packaging part and thus improving the packaging reliability. The principle has been explained and will not be repeated here.

[0135] See Figure 12 In the related technology, the pixel unit PX' includes red sub-pixels SPX-R, green sub-pixels SPX-G, and blue sub-pixels SPX-B arranged along the row direction. The center distance between adjacent sub-pixels is relatively large. A significant portion of the area of ​​both red and blue sub-pixels SPX-R is not used for white light synthesis, resulting in a small and poor white light synthesis area for pixel unit PX, leading to severe color fringing. The dashed line C4 represents the white light synthesis area of ​​pixel unit PX'.

[0136] In some embodiments, see Figure 12In the corresponding second sub-pixel SPX2 and the first sub-pixel SPX1 at the first receiving slot 161, the second extension segment 172, the fourth extension segment 174, the third sub-pixel SPX3, the fourth extension segment 174, and the second extension segment 172 are arranged along the first direction X. This divides the three sub-pixels in a single pixel unit PX into five parts along the first direction X, resulting in a larger total area for the three sub-pixels and a larger aperture ratio. It also makes the center distance between any two adjacent pairs of the five sub-pixels (second extension segment 172, fourth extension segment 174, third sub-pixel SPX3, fourth extension segment 174, and second extension segment 172) closer, allowing more area to be used for white light synthesis, thus alleviating the color fringing phenomenon. Furthermore, the third sub-pixel SPX3, located in the middle, can perform white light synthesis with the second extension segment 172 and the fourth extension segment 174 on one side, and also with the fourth extension segment 174 and the second extension segment on the other side. See also... Figure 2 The two dashed lines C1 circle the white light combining area of ​​the pixel unit PX, compared to related technologies. Figure 12 The embodiments provided in this application Figure 2 The area for white light synthesis is significantly increased.

[0137] In some embodiments, see Figure 2 The third extension segment 173 extends along the first direction X.

[0138] In some embodiments, see Figure 2 The fourth extension segment 174 extends along the second direction Y.

[0139] In some embodiments, see Figure 2 The dimension of the fourth extension segment 174 along the second direction Y is greater than the dimension of the third extension segment 173 along the first direction X. This allows the fourth extension segment 174 to have a larger extension length, which is beneficial to increasing the white light synthesis area of ​​the pixel unit PX.

[0140] In some embodiments, see Figure 2 The size of the fourth extension 174 along the second direction Y is larger than the size of the third sub-pixel SPX3 along the second direction Y. This allows the third sub-pixel SPX3 to be completely accommodated in the corresponding second accommodating slot 162, resulting in a larger overlap between the third sub-pixel SPX3 and the fourth extension 142 along the first direction X, which is beneficial for increasing the white light synthesis area of ​​the pixel unit PX.

[0141] In some embodiments, see Figure 2Within the same pixel unit PX, the ratio of the distance between the center of the second extension segment 172 and the center of the adjacent fourth extension segment 174 to the size of the pixel unit PX along the first direction X ranges from 1 / 6 to 1 / 5. This makes the center distance between the adjacent second extension segment 172 and fourth extension segment 174 closer, allowing more area to be used for white light synthesis, which helps to increase the white light synthesis area of ​​the pixel unit PX and thus alleviate the color fringing phenomenon. For example, this ratio can be 1 / 6, 1 / 5, or any value between 1 / 6 and 1 / 5.

[0142] In some embodiments, see Figure 2 Within the same pixel unit PX, the ratio of the distance between the center of the third sub-pixel SPX3 and the center of the adjacent fourth extension segment 174 to the size of the pixel unit PX along the first direction X ranges from 1 / 6 to 1 / 5. This makes the center distance between the adjacent third sub-pixel SPX3 and the fourth extension segment 174 closer, allowing more area to be used for white light synthesis, which helps to increase the white light synthesis area of ​​the pixel unit PX and thus alleviate the color fringing phenomenon. For example, this ratio can be 1 / 6, 1 / 5, or any value between 1 / 6 and 1 / 5.

[0143] In some embodiments, see Figure 3 Multiple pixel units PX are arranged in an array along the first direction X and the second direction Y, which helps to reduce the difficulty of arranging multiple pixel units PX.

[0144] In some embodiments, see Figure 3 The pixel arrangement structure 103 includes multiple rows of pixel units PX, and each row of pixel units PX includes multiple pixel units PX arranged along a first direction X. And / or, the pixel arrangement structure 103 includes multiple columns of pixel units PX, and each column of pixel units PX includes multiple pixel units PX arranged along a second direction Y. Multiple pixel units PX can be arranged in multiple rows and columns along the first and second directions.

[0145] In some embodiments, see Figure 3 All first sub-pixels SPX1 are evenly arranged along the first direction X and the second direction Y, which helps to improve the display uniformity of the pixel arrangement structure 103.

[0146] For example, the distance between the centers of two adjacent first sub-pixels SPX1 along the first direction X is equal to the distance between the centers of two adjacent first sub-pixels SPX1 along the second direction Y, which helps to improve the display uniformity of the pixel arrangement structure 103.

[0147] In some embodiments, see Figure 3All third sub-pixels SPX3 are evenly arranged along the first direction X and the second direction Y, which helps to improve the display uniformity of the pixel arrangement structure 103.

[0148] For example, the distance between the centers of two adjacent third sub-pixels SPX3 along the first direction X is equal to the distance between the centers of two adjacent third sub-pixels SPX3 along the second direction Y. This helps to improve the display uniformity of the pixel arrangement structure 103.

[0149] In some embodiments, see Figure 3 The centers of two adjacent first sub-pixels SPX1 along the first direction X are set opposite each other along the first direction X. In this way, the centers of two adjacent first sub-pixels SPX1 along the first direction X are aligned without misalignment, which helps to reduce the jaggedness.

[0150] In some embodiments, see Figure 3 The centers of two adjacent first sub-pixels SPX1 along the second direction Y are set opposite each other along the second direction Y. In this way, the centers of two adjacent first sub-pixels SPX1 along the second direction Y are aligned without misalignment, which helps to reduce the jaggedness.

[0151] In some embodiments, see Figure 3 The centers of two adjacent second sub-pixels SPX2 along the second direction Y are set opposite each other along the second direction Y. In this way, the centers of two adjacent second sub-pixels SPX2 along the second direction Y are aligned without misalignment, which helps to reduce the jaggedness.

[0152] In some embodiments, see Figure 3 The centers of two adjacent third sub-pixels SPX3 along the first direction X are set opposite each other along the first direction X. In this way, the centers of two adjacent third sub-pixels SPX3 along the first direction X are aligned without misalignment, which helps to reduce the jaggedness.

[0153] In some embodiments, see Figure 3 The centers of two adjacent third sub-pixels SPX3 along the second direction Y are set opposite each other along the second direction Y. In this way, the centers of two adjacent third sub-pixels SPX3 along the second direction Y are aligned without misalignment, which helps to reduce the jaggedness.

[0154] See Figures 1-5 A first implementation of the first sub-pixel SPX1 will be described.

[0155] See Figure 1In a first embodiment of the first sub-pixel SPX1, the first sub-pixel SPX1 surrounds and forms a first receiving groove 161. Thus, the number of first receiving grooves 161 is small, which can reduce the difficulty of fabricating the first sub-pixel SPX1.

[0156] In some embodiments, see Figure 1 The first sub-pixel SPX1 has a U-shaped shape.

[0157] In some embodiments, see Figure 1 The center of pixel unit PX is located in the third sub-pixel SPX3. This arrangement of the third sub-pixel SPX3 close to the center of pixel unit PX helps to improve the distribution uniformity of the third sub-pixel SPX3 and improve the display uniformity of pixel arrangement structure 103.

[0158] In some embodiments, see Figure 1 In the same pixel unit PX, a portion of the first sub-pixel SPX1, a portion of the second sub-pixel SPX2, the third sub-pixel SPX3, a portion of the second sub-pixel SPX2, and a portion of the first sub-pixel SPX1 are arranged sequentially along the first direction X. In this way, the third sub-pixel SPX3 located in the middle can perform white light synthesis with a portion of the first sub-pixel SPX1 and a portion of the second sub-pixel SPX2 on one side, and can also perform white light synthesis with a portion of the second sub-pixel SPX2 and a portion of the first sub-pixel SPX1 on the other side. In addition, it is also beneficial to increase the white light synthesis area of ​​the pixel unit PX. The principle has been explained and will not be repeated here.

[0159] In some embodiments, see Figure 3 The openings of the first receiving slots 161 of two adjacent pixel units PX along the first direction X all face the same side of the second direction Y, and the openings of the second receiving slots 162 of two adjacent pixel units PX along the first direction X all face the other side of the second direction Y. In this way, the setting pattern of the openings of the first receiving slots 161 of each pixel unit PX arranged along the first direction X is consistent, and the setting pattern of the openings of the second receiving slots 162 of each pixel unit PX arranged along the first direction X is consistent, which helps to reduce the design difficulty of each pixel unit PX.

[0160] In some embodiments, see Figure 3 The openings of the first receiving slots 161 of two adjacent pixel units PX along the second direction Y all face the same side of the second direction Y, and the openings of the second receiving slots 162 of two adjacent pixel units PX along the second direction Y all face the other side of the second direction Y. In this way, the setting pattern of the openings of the first receiving slots 161 of each pixel unit PX arranged along the second direction Y is consistent, and the setting pattern of the openings of the second receiving slots 162 of each pixel unit PX arranged along the second direction Y is consistent, which helps to reduce the design difficulty of each pixel unit PX.

[0161] In some embodiments, see Figure 3 All second sub-pixels SPX2 are evenly arranged along the first direction X and the second direction Y, which helps to improve the display uniformity of the pixel arrangement structure 103.

[0162] For example, the distance between the centers of two adjacent second sub-pixels SPX2 along the first direction X is equal to the distance between the centers of two adjacent second sub-pixels SPX2 along the second direction Y. This helps to improve the display uniformity of the pixel arrangement structure 103.

[0163] In some embodiments, see Figure 3 The centers of two adjacent second sub-pixels SPX2 along the first direction X are set opposite each other along the first direction X, so that the centers of two adjacent second sub-pixels SPX2 along the first direction X are aligned without misalignment.

[0164] In some embodiments, see Figure 4 and Figure 5 The openings of the first receiving grooves 161 of two adjacent pixel units PX along the first direction X face different sides of the second direction Y, and the openings of the second receiving grooves 162 of two adjacent pixel units PX along the first direction X face different sides of the second direction Y. In this way, the openings of the first receiving grooves 161 of each pixel unit PX arranged along the first direction X will not be concentrated on the same side of the second direction Y, and the openings of the second receiving grooves 162 of each pixel unit PX arranged along the first direction X will not be concentrated on the same side of the second direction Y. This helps to alleviate the uneven stress distribution on the pixel arrangement structure 103 caused by the openings of each first receiving groove 161 facing the same direction, and also alleviates the uneven stress distribution on the pixel arrangement structure 103 caused by the openings of each second receiving groove 162 facing the same direction.

[0165] See Figure 4 In an embodiment where the openings of the first receiving slots 161 of two adjacent pixel units PX along the second direction Y are both facing the same side of the second direction Y, the arrangement of each row of pixel units PX follows a consistent pattern, which helps to reduce the difficulty of arranging each row of pixel units PX.

[0166] See Figure 5 In other embodiments, the openings of the first receiving slots 161 of two adjacent pixel units PX along the second direction Y face different sides of the second direction Y, and the openings of the second receiving slots 162 of two adjacent pixel units PX along the second direction Y face different sides of the second direction Y, and the two adjacent pixel units PX along the second direction Y are symmetrically arranged. For example, two adjacent rows of pixel units PX can be symmetrically arranged.

[0167] In some embodiments, see Figure 2 , Figure 4 and Figure 5 The centers of two adjacent second sub-pixels SPX2 along the first direction X are offset along the first direction X. In this way, in two adjacent pixel units PX along the first direction X, the third extension segment 173 of one pixel unit PX and the first extension segment 171 of the other pixel unit PX can be arranged opposite each other along the first direction X. This is beneficial to increasing the size of the second sub-pixel SPX2 along the second direction Y, so that the second sub-pixel SPX2 can make fuller use of the space in the first receiving slot 161, which is beneficial to increasing the aperture ratio of the second sub-pixel SPX2.

[0168] See Figures 6-11 A second implementation of the first sub-pixel SPX1 will be described.

[0169] See Figure 6 and Figure 9 In a second embodiment of the first sub-pixel SPX1, the first sub-pixel SPX1 encloses and forms a plurality of first receiving slots 161 arranged along the first direction X. In the same first sub-pixel SPX1, the openings of two adjacent first receiving slots 161 face different sides of the second direction Y. In the same pixel unit PX, the openings of two adjacent second sub-pixels SPX2 face different sides of the second direction Y. This results in a larger number of first receiving slots 161 in the first sub-pixel SPX1, which helps to further reduce the distance between the centers of adjacent second extension segments 172 and fourth extension segments 174, as well as the distance between the centers of adjacent fourth extension segments 174 and third sub-pixel SPX3. This helps to increase the white light synthesis area of ​​the pixel unit PX, thereby alleviating the color fringing phenomenon.

[0170] In some embodiments, see Figure 6 and Figure 9 The centers of two adjacent second sub-pixels SPX2 along the first direction X are offset along the first direction X. This helps to improve the aperture ratio of the second sub-pixels SPX2. The principle has been explained and will not be repeated here.

[0171] In some embodiments, see Figure 7 The first sub-pixel SPX1 has two first receiving slots 161, and the second sub-pixel SPX2 and the third sub-pixel SPX3 each have two. This increases the number of second sub-pixels SPX2 and SPX3 in the pixel unit PX, as well as the number of second extension segments 172 of the first sub-pixel SPX1. This further increases the white light combining area of ​​the pixel unit PX, which is beneficial for improving the display effect of the pixel arrangement structure 103. Furthermore, the increased extension length of the first sub-pixel SPX1 helps extend its lifespan. Figure 7 The four dashed circles C2 in the middle show the white light synthesis area of ​​the pixel unit PX.

[0172] For example, see Figure 7 and Figure 8 The shape of the first sub-pixel SPX1 is S-shaped, and the S-shaped first sub-pixel SPX1 surrounds the two sets of first sub-pixels SPX1 and second sub-pixels SPX2.

[0173] In some embodiments, see Figure 9 and Figure 10 The first sub-pixel SPX1 has three first receiving slots 161, and the second sub-pixel SPX2 and the third sub-pixel SPX3 each have three slots. This further increases the number of second sub-pixels SPX2 and SPX3 in the pixel unit PX, as well as the number of second extension segments 172 of the first sub-pixel SPX1, thereby further increasing the white light synthesis area of ​​the pixel unit PX. This is beneficial for improving the display effect of the pixel arrangement structure 103. Furthermore, the increased extension length of the first sub-pixel SPX1 helps extend its lifespan. Figure 10 The six dashed circles C3 in the middle indicate the area of ​​white light synthesis.

[0174] For example, see Figure 10 and Figure 11 The first sub-pixel SPX1 has a snake-like shape, and the snake-like first sub-pixel SPX1 surrounds three groups of first sub-pixels SPX1 and second sub-pixels SPX2.

[0175] The display panel 100 provided in the embodiments of this application will be described below.

[0176] Figure 13 This is a schematic diagram of the structure of a display panel 100 according to one embodiment of this application. The display panel 100 includes the pixel arrangement structure 103 in the above embodiments, and the pixel arrangement structure 103 is disposed on one side of the substrate. The display panel 100 can be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, etc. This application uses an OLED display panel as an example for description.

[0177] See Figure 13The display panel 100 may have a first direction X, a second direction Y, and a third direction Z, all of which are different. The first direction X and the second direction Y can be any two different directions parallel to the display panel 100, and the third direction Z can be any direction intersecting the display panel 100. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. For example, the first direction X can be the width direction of the display panel 100, the second direction Y can be the length direction of the display panel 100, and the third direction Z can be the thickness direction of the display panel 100. The length, width, and thickness in the embodiments of this application are merely for descriptive convenience and do not imply any limitation on the dimensions. For example, the width can be greater than, equal to, or less than the length. The orientation of the display panel 100 can be consistent with the orientation of the substrate or other film layers.

[0178] For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other, and so on. Figure 13 The diagram shows mutually orthogonal X-axis, Y-axis, and Z-axis. The direction along the X-axis is called the first direction X, the direction along the Y-axis is called the second direction Y, and the direction along the Z-axis is called the third direction Z. The third direction Z is the normal direction relative to the plane containing the first direction X and the second direction Y. Furthermore, a view of various elements observed parallel to the plane containing the first direction X and the second direction Y is called a top view. Alternatively, the plane containing the first direction X and the second direction Y can be a plane parallel to the display surface of the display panel 100, and the third direction Z can be a direction parallel to the thickness direction of the display panel 100.

[0179] For example, the display panel 100 includes a display area AA with display function and a non-display area NA. The shape of the display area AA of the display panel 100 can be rectangular, or it can be other shapes such as square, circle or ellipse.

[0180] The following describes the sub-pixel SPX provided in the embodiments of this application.

[0181] Referring to 1, the display area AA includes multiple pixel units PX arranged in the first direction X and the second direction Y. Each pixel unit PX includes multiple sub-pixels SPX displaying different colors. In some embodiments, the pixel unit PX includes a first sub-pixel SPX1, a second sub-pixel SPX2, and a third sub-pixel SPX3, where any two of the first sub-pixels SPX1, second sub-pixels SPX2, and third sub-pixels SPX3 emit different colors. For example, one of the first sub-pixels SPX1, second sub-pixels SPX2, and third sub-pixels SPX3 may be a blue sub-pixel, one a green sub-pixel, and one a red sub-pixel. This allows the pixel unit PX to include three colors: red, green, and blue, eliminating the need to consider the SPR (Subpixel Rendering) algorithm and resulting in good single-point color reproduction.

[0182] In some implementations, the pixel unit PX includes not only red, blue, and green sub-pixels, but also sub-pixels that emit white or other colored light.

[0183] In some embodiments, see Figure 13 and Figure 14 The display panel 100 includes pixel circuits for driving corresponding light-emitting devices 130. A first sub-pixel SPX1 includes a first light-emitting device 130a, a second sub-pixel SPX2 includes a second light-emitting device 130b, and a third sub-pixel SPX3 includes a third light-emitting device 130c. One pixel circuit drives at least one light-emitting device 130 to emit light. For example, the display area AA includes a normal display area AA and a light-transmitting display area. The light-transmitting display area is the display area AA set for a corresponding sensor and has light-transmitting properties, while the normal display area is the display area AA not set for a corresponding sensor. In the normal display area, one pixel circuit drives one light-emitting device 130 to emit light. In the light-transmitting display area, one pixel circuit drives one or more light-emitting devices 130 to emit light.

[0184] For example, the shape of any one of the first sub-pixel SPX1, the second sub-pixel SPX2, and the third sub-pixel SPX3 may include a quadrilateral, a pentagon, a polygon, a circle, an ellipse, or other regular or irregular shapes.

[0185] refer to Figure 14 The display panel 100 includes an array substrate 101, an isolation structure 120, and multiple light-emitting devices 130.

[0186] refer to Figure 14 and Figure 22 The array substrate 101 includes a substrate 110, a pixel circuit layer disposed on the substrate 110, and a planarization layer 154. The substrate 110 provides support for the remaining film layers subsequently disposed. The pixel circuit layer includes pixel circuitry for driving the light-emitting device 130 to emit light. Figure 22 A transistor T in a pixel circuit is shown. A via is provided in the planarization layer 154, and the first electrode 131 is electrically connected to the transistor T in the pixel circuit layer through the via. Furthermore, the pixel circuit layer includes at least one insulating layer, which may include at least one of an inorganic layer and an organic layer. Additionally, the array substrate 101 includes scan lines providing the scan signal Scan and data lines providing the data signal Data to the pixel circuit.

[0187] refer to Figure 23 The pixel circuit includes a driving transistor T1 and a data transistor T2. The source of the data transistor T2 is connected to the data line that provides the data signal Data, the gate of the data transistor T2 is connected to the scan line that provides the scan signal Scan, and the drain of the data transistor T2 is connected to the gate of the driving transistor T1. The two ends of the storage capacitor C are respectively connected to the gate and the source of the driving transistor T1, and the drain of the driving transistor T1 is connected to the light-emitting device 130. Figure 23 This is one implementation of a pixel circuit; the pixel circuit described in this application is not limited to... Figure 23 The 2T1C pixel circuit shown can also be other pixel circuits, such as 7T1C, 8T1C pixel circuits, etc.

[0188] The isolation structure 120 provided in the embodiments of this application will be described in detail below.

[0189] In some embodiments, see Figure 14 The isolation structure 120 can refer to an undercut structure that is larger at the top and smaller at the bottom, capable of separating the light-emitting functional parts 133 corresponding to two adjacent isolation openings 12a. The isolation structure 120 can be a structure formed by a single film layer or a structure formed by stacking multiple film layers.

[0190] For example, the cross-sectional shape of the isolation structure 120 can be an inverted trapezoid with a larger top and a smaller bottom, a "T" shape, or an "I" shape, etc.

[0191] refer to Figure 13 and Figure 14An isolation structure 120 is located on one side of the array substrate 101 and encloses multiple isolation openings 12a. The multiple isolation openings 12a and multiple sub-pixels (SPXs) are correspondingly arranged. Light-emitting devices 130 of the multiple sub-pixels (SPXs) are correspondingly arranged in the multiple isolation openings 12a, with at least a portion of the light-emitting devices 130 disposed within their respective isolation openings 12a. The multiple isolation openings 12a include multiple first isolation openings 12a1, multiple second isolation openings 12a2, and multiple third isolation openings 12a3. The multiple light-emitting devices 130 are located on one side of the array substrate 101 and include multiple first light-emitting devices 130a, multiple second light-emitting devices 130b, and multiple third light-emitting devices 130c. The first light-emitting devices 130a are arranged corresponding to the first isolation opening 12a1, the second light-emitting devices 130b are arranged corresponding to the second isolation opening 12a2, and the third light-emitting devices 130c are arranged corresponding to the third isolation opening 12a3. In one embodiment, one light-emitting device 130 is correspondingly disposed with one isolation opening 12a. For example, a first light-emitting device 130a is correspondingly disposed with a first isolation opening 12a1, a second light-emitting device 130b is correspondingly disposed with a second isolation opening 12a2, and a third light-emitting device 130c is correspondingly disposed with a third isolation opening 12a3. At least a portion of the first light-emitting device 130a is disposed within the corresponding first isolation opening 12a1, at least a portion of the second light-emitting device 130b is disposed within the corresponding second isolation opening 12a2, and at least a portion of the third light-emitting device 130c is disposed within the corresponding third isolation opening 12a3. In another embodiment, multiple light-emitting devices 130 are correspondingly disposed with one isolation opening 12a. For example, multiple light-emitting devices 130 with the same emission color are corresponding to one isolation opening 12a.

[0192] In some embodiments, see Figure 3 and Figure 21aIn the isolation opening 12a and the corresponding sub-pixel SPX, the shape of the orthographic projection of the isolation opening 12a onto the substrate 110 is the same as the shape of the orthographic projection of the corresponding sub-pixel SPX onto the substrate 110. The isolation structure 120 encloses a plurality of isolation opening groups 12b. The isolation opening group 12b includes a first isolation opening 12a1, at least one second isolation opening 12a2, and at least one third isolation opening 12a3. In the isolation opening group 12b, the orthographic projection of the first isolation opening 12a1 on the substrate 110 is the first orthographic projection, which encloses at least one third receiving groove. At least one second isolation opening 12a2 is correspondingly disposed with at least one third receiving groove. The orthographic projection of the second isolation opening 12a2 on the substrate 110 is the second orthographic projection, which encloses a fourth receiving groove. In the corresponding second orthographic projection and third receiving groove, the second orthographic projection is located in the third receiving groove, and the groove opening of the third receiving groove faces away from the groove opening of the fourth receiving groove. At least one third isolation opening 12a3 is correspondingly disposed with at least one second isolation opening 12a2, and the orthographic projection of the third isolation opening 12a3 on the substrate 110 is located in the fourth receiving groove of the corresponding second isolation opening 12a2. In this way, the groove openings of the third receiving groove and the groove openings of the fourth receiving groove are arranged facing away from each other, which helps to prevent the groove openings of the third receiving groove and the groove openings of the fourth receiving groove from being concentrated on the same side, thus preventing the stress unevenness of the film layer in the corresponding area.

[0193] In some embodiments, see Figure 21a The isolation structure 120 includes multiple sub-isolation units 120b, each sub-isolation unit 120b enclosing an isolation opening group 12b. Within the same sub-isolation unit 120b, the sub-isolation unit 120b includes a first sub-isolation structure 1201, at least one second sub-isolation structure 1202, and at least one third sub-isolation structure 1203. The first sub-isolation structure 1201 surrounds the outer periphery of all second sub-isolation structures 1202 and all third sub-isolation structures 1203. A first isolation opening 12a1 is provided between the second sub-isolation structures 1202 and the first sub-isolation structure 1201. The second sub-isolation structures 1202 enclose a seventh receiving groove, and the third sub-isolation structures 1203 enclose a... An eighth receiving slot is formed, with at least one third sub-isolation structure 1203 correspondingly disposed with at least one second sub-isolation structure 1202. In the correspondingly disposed third sub-isolation structure 1203 and second sub-isolation structure 1202, the third sub-isolation structure 1203 is located in the seventh receiving slot of the second sub-isolation structure 1202. A second isolation opening 12a2 is provided between the third sub-isolation structure 1203 and the second sub-isolation structure 1202. The third isolation opening 12a3 is located within the eighth receiving slot, and the opening orientations of the seventh and eighth receiving slots are opposite to each other. The first sub-isolation structures 1201 of two adjacent sub-isolation units 120b are connected.

[0194] For example, see Figure 21a The first sub-isolation structure 1201 is in the shape of a quadrilateral ring.

[0195] For example, see Figure 21a The second sub-isolation structure 1202 is U-shaped. Figure 3 The opening of the U-shape in the middle faces upwards.

[0196] For example, see Figure 21a The third sub-isolation structure 1203 is U-shaped. Figure 3 The opening of the U-shape in the middle faces downwards.

[0197] In one example, see Figure 14 The isolation structure 120 includes a first isolation portion 121 and a second isolation portion 122. The second isolation portion 122 is located on the side of the first isolation portion 121 facing the substrate 110. The orthographic projection of the second isolation portion 122 on the substrate 110 lies within the orthographic projection of the first isolation portion 121 on the substrate 110, thus forming an undercut structure that is larger at the top and smaller at the bottom, i.e., the isolation structure 120 has an "eaves". Therefore, during the formation of the light-emitting functional portion 133, the isolation structure 120 can separate the light-emitting functional portions 133 in two adjacent isolation openings 12a. For example, the width of the first isolation portion 121 is greater than the width of the second isolation portion 122. Consequently, the two ends of the first isolation portion 121 protrude compared to the sides of the second isolation portion 122; this shape of the isolation structure 120 is also referred to as a hanging shape. The second isolation portion 122 and the first isolation portion 121 are made of different materials, and the etching rate of the first isolation portion 121 is lower than the etching rate of the second isolation portion 122. The second isolation portion 122 is made of a conductive material, specifically including at least one of aluminum (Al) and aluminum alloys. The aluminum alloy may include at least one of aluminum-neodymium alloy (AlNd), aluminum-yttrium alloy (AlY), or aluminum-silicon alloy (AlSi). The first isolation portion 121 may be a single-layer or multi-layer structure. If the first isolation portion 121 is a single-layer structure, its material may include at least one of titanium, titanium nitride, molybdenum, tungsten, molybdenum-tungsten alloy, or molybdenum-niobium alloy. See also... Figure 16 When the first isolation portion 121 has a multi-layer structure, one layer of the first isolation portion 121 is made of at least one of titanium, titanium nitride, molybdenum, tungsten, molybdenum-tungsten alloy or molybdenum-niobium alloy, and the other layer of the first isolation portion 121 may be made of conductive oxide or inorganic insulating material, such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0198] In some embodiments, reference Figure 15The isolation structure 120 may further include a third isolation portion 123 located on the side of the second isolation portion 122 near the array substrate 101. The third isolation portion 123 protrudes relative to the second isolation portion 122 in the direction toward the isolation opening 12a. The orthographic projection of the second isolation portion 122 on the array substrate 101 lies within the orthographic projection of the third isolation portion 123 on the array substrate 101. The material of the third isolation portion 123 may include at least one of molybdenum (Mo), titanium (Ti), titanium nitride (TiN), molybdenum-tungsten alloy (MoW), or molybdenum-niobium alloy (MoNb).

[0199] The pixel limiting layer 155 provided in the embodiments of this application will be described below.

[0200] In one implementation, see Figure 15 and Figure 17 The display panel 100 may further include a pixel defining layer 155, and an isolation structure 120 is disposed on the pixel defining layer 155. The pixel defining layer 155 is disposed between the substrate 110 and the isolation structure 120, and encloses a plurality of pixel openings. The plurality of pixel openings are correspondingly disposed with a plurality of light-emitting functional parts 133, and at least a portion of the light-emitting functional parts 133 is disposed within the corresponding pixel opening. The pixel defining layer 155 is provided with pixel openings communicating with the isolation openings 12a. Specifically, the pixel defining layer 155 is provided with a first pixel opening communicating with a first isolation opening 12a1, a second pixel opening communicating with a second isolation opening 12a2, and a third pixel opening communicating with a third isolation opening 12a3. The areas of the orthographic projections of the first pixel opening, the second pixel opening, and the third pixel opening on the array substrate 101 may be the same or different. The shapes of the orthographic projections of the pixel openings and the corresponding isolation openings 12a on the array substrate 101 may be the same or different. Generally, the area of ​​the orthographic projection of the isolation opening 12a onto the array substrate 101 is larger than the area of ​​the orthographic projection of the pixel opening communicating with the isolation opening 12a onto the array substrate 101. The orthographic projections of the pixel openings onto the array substrate 101 and the orthographic projections of the isolation opening 12a onto the array substrate 101 overlap. The pixel defining layer 155 is made of an inorganic material, such as an inorganic insulating material formed using at least one of silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxynitride (SiON). The pixel defining layer 155 can be a single layer, a double layer, or multiple layers. The double or multiple layers of the pixel defining layer 155 can be layers made of different materials or layers prepared under different conditions.

[0201] In one implementation, see Figure 17The pixel limiting layer 155 includes multiple sub-layers, including a first sub-layer 1551 and a second sub-layer 1552 stacked sequentially along the direction away from the array substrate 101, that is, the pixel limiting layer 155 can adopt a double-layer design.

[0202] For example, the first sublayer 1551 has better film-forming properties than the second sublayer 1552. That is, under the same thickness conditions, the first sublayer 1551 can better cover the stepped structure formed by the first electrode 131 than the second sublayer 1552, without producing cracks. Conversely, to obtain the same stepped coverage effect, the thickness of the first sublayer 1551 needs to be thinner than the thickness of the second sublayer 1552. That is, the thickness requirement for the first sublayer 1551 is relatively low, which is conducive to product thinning. In addition, the better film-forming properties are reflected in the better coverage of the formed film, which is denser and more conducive to the isolation of water vapor.

[0203] For example, the second sublayer 1552 has better etching resistance than the first sublayer 1551. Since the side of the pixel defining layer 155 facing away from the array substrate 101 will be etched during the fabrication of the display panel 100, by selecting a material with stronger etching resistance as the second sublayer 1552, the etching resistance of the pixel defining layer 155 can be improved, thereby further improving the reliability of the display panel 100.

[0204] For example, the first sublayer 1551 and the second sublayer 1552 are made of different materials. For instance, the first sublayer 1551 is made of silicon nitride, and the second sublayer 1552 is made of silicon oxide.

[0205] For example, the thickness of the first sublayer 1551 is greater than or equal to 1000 angstroms and less than or equal to 5000 angstroms. For instance, the thickness of the first sublayer 1551 is 1000 angstroms, 2000 angstroms, 3000 angstroms, 4000 angstroms, 5000 angstroms, etc.

[0206] For example, the thickness of the second sublayer 1552 is greater than or equal to 500 angstroms and less than or equal to 3000 angstroms. For instance, the thickness of the second sublayer 1552 is 500 angstroms, 1000 angstroms, 2000 angstroms, 3000 angstroms, etc.

[0207] In another embodiment, the isolation structure 120 is disposed within the receiving groove of the pixel limiting layer 155. Alternatively, the pixel limiting layer 155 may not be provided in the display panel 100, and the isolation structure 120 may be disposed on one side of the array substrate 101, with the isolation structure 120 in contact with one side of the array substrate 101. This application embodiment is described with the display panel 100 having a pixel limiting layer 155 provided.

[0208] In some embodiments, see Figure 3 and Figure 21bIn the pixel opening and the corresponding sub-pixel SPX, the shape of the orthographic projection of the pixel opening onto the substrate 110 is the same as the shape of the orthographic projection of the corresponding sub-pixel SPX onto the substrate 110. The pixel defining layer 155 encloses a plurality of pixel opening groups 15b. The pixel opening group 15b includes a first pixel opening 15a1, at least one second pixel opening 15a2, and at least one third pixel opening 15a3. In pixel aperture group 15b, the orthographic projection of the first pixel aperture 15a1 on the substrate 110 is a third orthographic projection, which encloses at least one fifth receiving groove. At least one second pixel aperture 15a2 is correspondingly disposed with at least one fifth receiving groove. The orthographic projection of the second pixel aperture 15a2 on the substrate 110 is a fourth orthographic projection, which encloses a sixth receiving groove. In the corresponding fourth orthographic projection and fifth receiving groove, the fourth orthographic projection is located in the fifth receiving groove, and the groove opening of the fifth receiving groove faces away from the groove opening of the sixth receiving groove. At least one third pixel aperture 15a3 is correspondingly disposed with at least one second pixel aperture 15a2, and the orthographic projection of the third pixel aperture 15a3 on the substrate 110 is located in the sixth receiving groove of the corresponding second pixel aperture 15a2. In this way, the groove openings of the fifth receiving groove and the groove openings of the sixth receiving groove are set away from each other, which helps to prevent the groove openings of the fifth receiving groove and the groove openings of the sixth receiving groove from being concentrated on the same side, thus preventing the stress unevenness of the film layer in the corresponding area.

[0209] The light-emitting device 130 provided in the embodiments of this application will be described in detail below.

[0210] For example, the first light-emitting device 130a, the second light-emitting device 130b, and the third light-emitting device 130c emit light of different colors; see also Figure 14 The first light-emitting device 130a, the second light-emitting device 130b, and the third light-emitting device 130c each include a first electrode 131, a light-emitting functional part 133, and a second electrode 132 stacked together. The first electrode 131 is disposed on the array substrate 101, and a pixel limiting layer 155 covers the end of the first electrode 131. A pixel opening is provided on the pixel limiting layer 155, through which the first electrode 131 is exposed. The light-emitting functional part 133 of the first light-emitting device 130a, the second light-emitting device 130b, and the third light-emitting device 130c covers the sidewall of the pixel opening of the pixel limiting layer 155 and the side of the pixel limiting layer 155 facing away from the array substrate 101. Each light-emitting functional part 133 is located within the pixel opening and is in contact with the first electrode 131.

[0211] See Figure 17 and Figure 18The second electrodes 132 of the first light-emitting device 130a, the second light-emitting device 130b, and the third light-emitting device 130c respectively cover the corresponding light-emitting functional parts 133. The second electrodes 132 are electrically connected to the isolation structure 120. For example, the second electrodes 132 are connected to the second isolation part 122 of the isolation structure 120, and / or, the second electrodes 132 are connected to the third isolation part 123 of the isolation structure 120. Specifically, the second electrodes 132 are connected to the portion of the third isolation part 123 that protrudes from the second isolation part 122 in the direction toward the isolation opening 12a. When the isolation structure 120 includes a three-layer structure of a first isolation part 121, a second isolation part 122, and a third isolation part 123, the second electrodes 132 can extend to the side surface of the third isolation part 123 facing away from the array substrate 101 to connect with the third isolation part 123. In this case, the second electrodes 132 may or may not be connected to the second isolation part 122.

[0212] For example, one of the first electrode 131 and the second electrode 132 can be an anode, and the other of the first electrode 131 and the second electrode 132 can be a cathode. This application embodiment uses the example of the first electrode 131 being the anode and the second electrode 132 being the cathode for illustration. The first electrode 131 of the light-emitting device 130 can be connected to the pixel circuit through a via, so that the pixel circuit drives the light-emitting device 130 to emit light.

[0213] For example, the first electrode 131 may include a multilayer structure, such as a reflective layer and a pair of conductive oxide layers covering the upper and lower surfaces of the reflective layer, respectively. The reflective layer can be formed, for example, using silver, a metallic material with excellent light reflectivity. Each conductive oxide layer can be formed, for example, from a transparent conductive oxide such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), or IGZO (Indium Gallium Zinc Oxide). The second electrode 132 is formed, for example, from a metallic material such as an alloy of magnesium and silver (MgAg).

[0214] In some embodiments, see Figure 3 and Figure 21cAll first electrodes 131 are located in the first conductive layer 131a. In the first electrode 131 and its corresponding sub-pixel SPX, the shape of the orthographic projection of the first electrode 131 onto the substrate 110 is the same as the shape of the orthographic projection of the corresponding sub-pixel SPX onto the substrate 110; that is, the shapes of the first electrode 131 and the sub-pixel SPX are the same. Multiple first electrodes 131 are arranged in multiple first electrode units 131b, and each first electrode unit 131b corresponds to a pixel unit PX. Each first electrode unit 131b includes a first electrode 1311 of a first sub-pixel SPX1, at least one first electrode 1312 of a second sub-pixel SPX2, and at least one first electrode 1313 of a third sub-pixel SPX3. Within the same first electrode unit 131b, the first electrode 1311 of the first sub-pixel SPX1 encloses at least one first receiving groove 161. At least one first electrode 1312 of a second sub-pixel SPX2 is correspondingly disposed with at least one first receiving groove 161. The first electrode 1312 of the second sub-pixel SPX2 surrounds and forms a second receiving groove 162. In the corresponding first electrode 1312 of the second sub-pixel SPX2 and the first receiving groove, the first electrode 1312 of the second sub-pixel SPX2 is located in the first receiving groove 161. The groove opening of the first receiving groove 161 faces away from the groove opening of the second receiving groove 162. At least one first electrode 1313 of a third sub-pixel SPX3 is correspondingly disposed with at least one first electrode 1312 of the second sub-pixel SPX2. The first electrode 1313 of the third sub-pixel SPX3 is located in the second receiving groove 162 of the corresponding first electrode 1312 of the second sub-pixel SPX2.

[0215] In some embodiments, see Figure 3 and Figure 21dAll second electrodes 132 are located in the second conductive layer 132a. In the second electrode 132 and its corresponding sub-pixel SPX, the shape of the orthographic projection of the second electrode 132 onto the substrate 110 is the same as the shape of the orthographic projection of the corresponding sub-pixel SPX onto the substrate 110; that is, the second electrode 132 and the sub-pixel SPX have the same shape. Multiple second electrodes 132 are arranged in multiple second electrode units 132b, and each second electrode unit 132b corresponds to a pixel unit PX. Each second electrode unit 132b includes a second electrode 1321 for a first sub-pixel SPX1, a second electrode 1322 for at least one second sub-pixel SPX2, and a second electrode 1323 for at least one third sub-pixel SPX3. Within the same second electrode unit 132b, the second electrode 1321 of the first sub-pixel SPX1 encloses at least one first receiving groove 161. At least one second electrode 1322 of a second sub-pixel SPX2 is correspondingly disposed with at least one first receiving groove 161. The second electrode 1322 of the second sub-pixel SPX2 surrounds and forms a second receiving groove 162. In the corresponding second electrode 1322 of the second sub-pixel SPX2 and the first receiving groove 161, the second electrode 1322 of the second sub-pixel SPX2 is located in the first receiving groove 161. The groove opening of the first receiving groove 161 faces away from the groove opening of the second receiving groove 162. At least one second electrode 1323 of a third sub-pixel SPX3 is correspondingly disposed with at least one second electrode 1322 of the second sub-pixel SPX2. The second electrode 1323 of the third sub-pixel SPX3 is located in the second receiving groove 162 of the corresponding second electrode 1322 of the second sub-pixel SPX2.

[0216] Figure 24 This is a schematic diagram of a light-emitting functional unit 133 according to one embodiment of this application. The light-emitting functional unit 133 of at least one of the first light-emitting device 130a, the second light-emitting device 130b, and the third light-emitting device 130c includes a hole injection layer HIL, a hole transport layer HTL, an electron blocking layer EBL, a light-emitting material layer EML, a hole blocking layer HBL, an electron transport layer ETL, and an electron injection layer EIL, stacked along a direction away from the array substrate 101 (i.e., the third direction Z). The light-emitting functional unit 133 may include a single light-emitting material layer EML, or a stacked light-emitting structure including multiple light-emitting material layers EML.

[0217] In order for the light-emitting functional unit 133 to emit light, a pixel voltage is provided to the first electrode 131 and a common voltage is provided to the second electrode 132, respectively, forming a potential difference between the first electrode 131 and the second electrode 132, so that the light-emitting functional unit 133 disposed between the first electrode 131 and the second electrode 132 emits light. In one embodiment, if a potential difference is formed between the first electrode 131 and the second electrode 132 of the first light-emitting device 130a, the light-emitting material layer EML of the light-emitting functional unit 133 emits blue light; if a potential difference is formed between the first electrode 131 and the second electrode 132 of the second light-emitting device 130b, the light-emitting material layer EML of the light-emitting functional unit 133 emits green light; and if a potential difference is formed between the first electrode 131 and the second electrode 132 of the third light-emitting device 130c, the light-emitting material layer EML of the light-emitting functional unit 133 emits red light.

[0218] In this configuration, the pixel voltage of the first electrode 131 is provided by the pixel circuit, and the common voltage of the second electrode 132 is provided by the isolation structure 120. Specifically, the second electrode 132 is electrically connected to the isolation structure 120, and the common voltage is supplied to the second electrode 132 by providing the isolation structure 120. That is, the isolation structure 120 has the function of supplying a common voltage to the second electrode 132.

[0219] It should be noted that the effective light-emitting area of ​​the light-emitting device 130 is determined by the contact area between the light-emitting functional part 133 and the first electrode 131; that is, the area in contact between the light-emitting functional part 133 and the first electrode 131 is the effective light-emitting area. In the embodiment where a pixel limiting layer 155 is provided on the substrate 110, the area enclosed by the end of the pixel opening near the substrate 110 is the effective light-emitting area. The arrangement of the pixel openings can be the same as the arrangement of the light-emitting devices 130. The distance between the effective light-emitting areas of two light-emitting devices 130 can be equal to the distance between two pixel openings. The distance between two pixel openings refers to the distance between the side of one pixel opening facing the substrate 110 and the side of the other pixel opening facing the substrate 110.

[0220] In some embodiments, see Figure 14 and Figure 20The display panel 100 further includes a first encapsulation layer, which includes a plurality of encapsulation portions 140. Each encapsulation portion 140 is located on the side of the second electrode 132 facing away from the array substrate 101, and extends through the sidewall of the isolation structure 120 to the side of the isolation structure 120 facing away from the array substrate 101. The orthographic projections of the plurality of encapsulation portions 140 on the array substrate 101 may overlap or not overlap. The plurality of encapsulation portions 140 includes a plurality of first encapsulation portions 140a corresponding to a plurality of first light-emitting devices 130a, a plurality of second encapsulation portions 140b corresponding to a plurality of second light-emitting devices 130b, and a plurality of third encapsulation portions 140c corresponding to a plurality of third light-emitting devices 130c. The first encapsulation portion 140a is disposed on the side of the corresponding first light-emitting device 130a facing away from the array substrate 101, the second encapsulation portion 140b is disposed on the side of the corresponding second light-emitting device 130b facing away from the array substrate 101, and the third encapsulation portion 140c is disposed on the side of the corresponding third light-emitting device 130c facing away from the array substrate 101.

[0221] For example, see Figure 19 The encapsulation portion 140 includes a main body portion 141 and an extension portion 142. The main body portion 141 is located within the isolation opening 12a and is disposed on the side of the corresponding light-emitting device 130 facing away from the substrate 110 and on the sidewall of the isolation structure 120. The extension portion 142 is located on the side of the isolation structure 120 facing away from the substrate 110. The main body portion 141 includes a first segment 1411 and a second segment 1412 that are connected to each other. The first segment 1411 is located within the isolation opening 12a and is disposed on the side of the light-emitting device 130 facing away from the substrate 110. The second segment 1412 is located on the side of the isolation structure 120 facing the isolation opening 12a.

[0222] See some examples. Figure 19 The surface of the first segment 1411 facing away from the substrate 110 and the surface of the second segment 1412 facing away from the isolation structure 120 are at least partially connected to each other to enclose and form a spacer space 143. See also other examples. Figure 20 The surface of the first segment 1411 facing away from the substrate 110 and the surface of the second segment 1412 facing away from the isolation structure 120 may not be connected.

[0223] In some embodiments, see Figure 20 The display panel 100 further includes a second encapsulation layer 152 and a third encapsulation layer 153. The second encapsulation layer 152 covers the isolation structure 120 and the encapsulation portion 140, and the third encapsulation layer 153 covers the second encapsulation layer 152. Both the first encapsulation layer and the third encapsulation layer 153 are inorganic materials, including silicon nitride (SiN) and silicon oxide (SiO2). XThe second encapsulation layer 152 is an organic insulating material, such as epoxy resin, acrylic resin, or other resin materials. The second encapsulation layer 152 and the third encapsulation layer 153 are continuously disposed on at least the entire display area AA, with a portion also disposed on the non-display area NA. The display panel 100 includes at least one of the second encapsulation layer 152 and the third encapsulation layer 153.

[0224] In some embodiments, the display panel 100 may further include at least one film layer such as a touch layer, a polarizer, a color filter substrate 110, and a protective cover. This film layer may also be bonded to the display panel 100 via an adhesive layer such as OCA (Optical Clear Adhesive).
