Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0034] Various modifications and variations can be made to this invention without departing from its spirit or scope, as will be apparent to those skilled in the art. Therefore, this invention is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this invention can be combined with each other without contradiction.

[0035] Figure 1 This is a schematic diagram of a display module in related technologies. Figure 1 This diagram illustrates the film layer structure of a Micro-LED display product. Figure 1 As shown, a light-emitting device 002 is disposed on the array layer 001, a touch layer 003 is disposed on the light-emitting device 002, a polarizer 004 is disposed on the touch layer 003, and a glass cover plate 005 is disposed on the polarizer 004. A graphite layer 006 is disposed on the back side of the substrate 00, and an opening is provided on the graphite layer 006. A light sensor 007, such as an ambient light sensor, is disposed at the corresponding position of the opening. The light sensor 007 can be used to adaptively adjust the screen brightness.

[0036] The inventors discovered that using a polarizer 004 as an anti-reflection structure in wearable products of related technologies reduces the screen's reflectivity to ambient light. The polarizer 004 has a relatively high transmittance of approximately 42%, and after placing the light sensor 007 on the back of the screen, the overall screen transmittance can meet the light sensor 007's light requirements. However, during display, the light emitted by the light-emitting device 002 needs to pass through the touch layer 003, the polarizer 004, and the glass cover 005 before exiting. The light efficiency attenuation ratio of the touch layer 003 is approximately 10%, that of the polarizer 004 is approximately 58%, and that of the glass cover 005 is approximately 50%. The light efficiency attenuation ratio is the ratio of light emitted through a certain film layer to light incident on that film layer. It is evident that the polarizer 004 has a relatively large light efficiency attenuation ratio. Polarizer 004 is used as the anti-reflection structure. The high transmittance of polarizer 004 can meet the requirements of light sensor 007 for the overall screen transmittance. However, the high light efficiency attenuation ratio of polarizer 004 seriously affects the display brightness and leads to high power consumption.

[0037] To address the problems existing in related technologies, embodiments of the present invention provide a display panel in which a black matrix is ​​set as an anti-reflection structure, and an additional light-transmitting opening is added to the black matrix. When designing the position of the light-transmitting opening, space for setting the opening is made by reducing the total area of ​​the electrodes within the pixel area. The light sensor is positioned corresponding to the added light-transmitting opening, which satisfies the light sensor's requirements for screen transmittance. Furthermore, during display, the black matrix does not block the forward light emission of the light-emitting device, ensuring the light emission effect of the device and helping to reduce product power consumption. Embodiments of the present invention optimize screen transmittance by adding a light-transmitting opening to the black matrix, meeting the transmittance requirements of the under-display light sensor, and reducing display power consumption. The above is the main technical concept of embodiments of the present invention; the following specific embodiments are used to illustrate the technical solution of the present invention.

[0038] Figure 2 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 3 To remove Figure 2 A schematic diagram of the first black matrix and the light-emitting device. Figure 4 for Figure 2 A schematic diagram of a cross-section at the location of the tangent AA′.

[0039] Combination Figures 2 to 4 The display panel includes a substrate 00, multiple pixel circuits 10, multiple electrode groups 20, multiple light-emitting devices 30, and a first black matrix 41 located on one side of the substrate 00. The electrode group 20 includes a first electrode 21 and a second electrode 22 disposed opposite to each other, and the first electrode 21 is coupled to the pixel circuits 10. Figure 4 Only one transistor in the pixel circuit 10 is shown in the diagram. The first electrode 21 is coupled to the pixel circuit 10 through a via penetrating the insulating layer. The light-emitting device 30 is coupled to the electrode group 20. Specifically, the light-emitting device 30 includes an anode and a cathode, one of which is electrically connected to the first electrode 21, and the other is electrically connected to the second electrode 22. For example, the first electrode 21 is the anode electrode, and the second electrode 22 is the cathode electrode. The light-emitting device 30 can be a Micro-LED or a Mini-LED (Mini Light Emitting Diode).

[0040] exist Figure 2 and Figure 4 The diagram illustrates that the first black matrix 41 includes a first opening K1 and a second opening K2. Figure 3 This is a partial top view of the display panel. Figure 3 Although the first black matrix 41 is not shown, dashed lines are used to indicate the positions of the first opening K1 and the second opening K2 when the first black matrix 41 is present, in order to clearly illustrate the overlap between the opening and the electrode group 20. Figure 3 and Figure 4 It can be seen that, along the direction e perpendicular to the plane containing the substrate 00, the first opening K1 at least partially overlaps with the electrode group 20, while the second opening K2 does not overlap with the electrode group 20. It can be understood that the top view of the display panel is parallel to the direction perpendicular to the plane containing the substrate 00, and in the top view, the orthographic projection of a certain structure onto the plane containing the substrate 00 coincides with the pattern of that structure. Figure 3 As shown in the schematic top view, the first opening K1 overlaps with a portion of the first electrode 21 in the electrode group 20 and also overlaps with a portion of the second electrode 22 in the same electrode group 20. Since the light-emitting device 30 and the electrode group 20 are connected correspondingly and perpendicular to the plane of the substrate 00, the light-emitting device 30 at least partially overlaps with the electrode group 20. Therefore, it can be understood that the light-emitting device 30 overlaps with the first opening K1. The second opening K2 does not overlap with the electrode group 20, and therefore, the second opening K2 does not overlap with the light-emitting device 30. In the first black matrix 41, the first opening K1 can be understood as a pixel opening, and the second opening K2 can be understood as a light-transmitting opening.

[0041] Figure 2 The horizontal and vertical dotted lines divide the display panel into multiple pixel areas of equal size. These pixel areas include a first pixel area P1 and a second pixel area P2, both of equal size. Each pixel area P1 and P2 includes a light-emitting device 30. The number of light-emitting devices 30 in each pixel area can be the same or different, and the light-emitting colors of the devices 30 in each pixel area can be the same or different.

[0042] Combination Figure 3 As can be seen, the total area of ​​the first electrode 21 in the first pixel region P1 is smaller than the total area of ​​the first electrode 21 in the second pixel region P2. The first pixel region P1 includes a second opening K2. In conventional designs, the first electrodes in two pixel regions of equal area are arranged in the same way, and the total area of ​​the first electrodes is equal. However, in this embodiment of the invention, the total area of ​​the first electrode 21 in the first pixel region P1 is reduced, and a second opening K2 of the first black matrix 41 is provided in the first pixel region P1. The second opening K2 occupies a certain area and does not overlap with the electrode group 20. That is, by reducing the total area of ​​the first electrode 21, space is left in the first pixel region P1 to provide space for the second opening K2, allowing the area of ​​the second opening K2 to be relatively large.

[0043] Figure 2 The illustration shows that the arrangement of the light-emitting devices 30 in the first pixel region P1 and the second pixel region P2, which have equal areas, is different. A second opening K2 is provided in the first pixel region P1. In other embodiments, Figure 5 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 5As shown, the intersecting dashed lines divide the display panel into multiple pixel areas of equal size. The display panel includes a first pixel area P1 and a second pixel area P2 of equal size. The light-emitting devices 30 in the first pixel area P1 and the second pixel area P2 are arranged in the same way. The first electrode 21 in the first pixel area P1 ( Figure 5 The total area of ​​(not shown) is less than the total area of ​​the first electrode 21 in the second pixel area P2, and the first pixel area P1 includes the second opening K2. Figure 5 The first electrode 21 and the second electrode 22 are not shown in the figure. It can be understood that the first electrode 21 and the second electrode 22 form an electrode group for electrical connection with the light-emitting device 30. The first electrode 21 and the second electrode 22 are respectively arranged below each light-emitting device 30. Figure 5 Alternatively, the embodiment can make room for the second opening K2 by reducing the total area of ​​the first electrode 21 within the first pixel area P1.

[0044] The display panel provided in this embodiment of the invention includes an electrode group 20 and a light-emitting device 30. The light-emitting device 30 is coupled to a pixel circuit 10 through a first electrode 21 in the electrode group 20. A first black matrix 41 includes a first opening K1 and a second opening K2. The first opening K1 is a pixel opening, and the second opening K2 is a light-transmitting opening. For a first pixel area P1 and a second pixel area P2 with equal areas, by reducing the total area of ​​the first electrode 21 within the first pixel area P1, space is left within the first pixel area P1 to add the second opening K2, allowing the area of ​​the second opening K2 to be relatively large. In application, a light sensor can be configured corresponding to the second opening K2. Ambient light is received by the light sensor through the second opening K2, meeting the light sensor's requirements for screen transmittance. During display, the first black matrix 41 does not block the forward light emission of the light-emitting device 30, ensuring the light emission effect of the light-emitting device 30 and reducing product power consumption. This embodiment of the invention optimizes screen transmittance by adding a second opening K2 to the first black matrix 41, meeting the transmittance requirements of the under-display light sensor and reducing display power consumption.

[0045] In this embodiment of the invention, compared to a second pixel region P2 with the same area, the total area of ​​the first electrode 21 in the first pixel region P1 is reduced, leaving more space in the first pixel region P1 for the second opening K2 of the first black matrix 41 to be arranged in the first pixel region P1. The second opening K2 does not overlap with the electrode group 20, nor with the pixel circuit, and serves as a light-transmitting opening.

[0046] In some implementations, the electrode group 20 within the pixel area includes only the in-situ electrode group and excludes redundant electrode groups. The in-situ electrode group refers to the electrode group 20 originally designed to be coupled to the light-emitting device 30. When redundant electrode groups are not designed in the panel, the in-situ electrode group can be used to repair defective pixels. If a lighting test reveals that a light-emitting device 30 at a certain location is defective and cannot be lit normally, the defective light-emitting device is removed, and then a light-emitting device 30 is re-bonded at the original location for repair. Based on the design concept of this embodiment, the total area of ​​the first electrode 21 can be reduced by decreasing the number of first electrodes 21 within the first pixel area P1 or by reducing the size of a single first electrode 21, thereby leaving space in the first pixel area P1 for adding the second opening K2 of the first black matrix 41. In other words, the setting of the second opening K2 within the first pixel area P1 occupies part of the position of the in-situ electrode group.

[0047] In other embodiments, the electrode group 20 within the pixel area includes an in-situ electrode group and a redundant electrode group. In the scheme including the redundant electrode group, the redundant electrode group is arranged in conjunction with the in-situ electrode group, and the redundant electrode group and its corresponding in-situ electrode group share the first electrode 21. When a defect is found in the light-emitting device 30 coupled to the in-situ electrode group during the lighting test, a light-emitting device 30 of the same color is coupled at the corresponding redundant electrode group position for pixel repair. It is understood that in the scheme with the redundant electrode group, the area of ​​the first electrode 21 will be relatively large. Based on the design concept of the embodiments of the present invention, in the scheme including the redundant electrode group, the size of a single first electrode 21 can be reduced by reducing the number of redundant electrode groups in the first pixel area P1, thereby reducing the total area of ​​the first electrode 21, leaving space in the first pixel area P1 for adding the second opening K2 of the first black matrix 41; or the number of both the redundant electrode group and the in-situ electrode group in the first pixel area P1 can be reduced simultaneously, thereby reducing the total area of ​​the first electrode 21 by reducing the number of the first electrode 21, thus leaving space in the first pixel area P1 for adding the second opening K2 of the first black matrix 41. In a scheme that includes a redundant electrode group within a pixel region, the first pixel region P1 includes a second opening K2, which occupies part of the position of the redundant electrode group, or the second opening K2 occupies part of the position of the redundant electrode group and part of the in-situ electrode group.

[0048] The present invention can be used for display panels with or without redundant electrode groups in the pixel area. The structure in the first pixel area P1 is set so that space is left in the first pixel area P1 to arrange the second opening K2 of the first black matrix 41. By adding the second opening K2 to the first black matrix 41, the transmittance of the screen can be optimized to meet the transmittance requirements of the under-display light sensor, and the power consumption of the display can be reduced.

[0049] For example, such as Figure 2 As shown, the area of ​​the second opening K2 is larger than the area of ​​the first opening K1. The first opening K1 is a pixel opening, and the second opening K2 is a light-transmitting opening. In this embodiment of the invention, by reducing the total area of ​​the first electrode 21 within the first pixel region P1, space is left within the first pixel region P1 to accommodate the second opening K2, resulting in a relatively larger area for the second opening K2. In applications, more ambient light passes through the second opening K2, which is beneficial for improving the performance of the light sensor.

[0050] Furthermore, the first opening K1 is a pixel opening, and its purpose is to expose the light-emitting device 30 and ensure its light emission. In some embodiments, the light-emitting device 30 is partially surrounded by the first black matrix 41, and the area of ​​the first opening K1 is approximately equal to the area of ​​the corresponding light-emitting device 30. In other embodiments, the light-emitting device 30 is located on the side of the film layer containing the first black matrix 41 away from the substrate, and the first opening K1 of the first black matrix 41 exposes the electrode group 20 coupled to the light-emitting device 30. In this embodiment, the area of ​​the first opening K1 can be smaller than the area of ​​the corresponding light-emitting device 30.

[0051] For example, the area of ​​the second opening K2 is S, where S ≥ 7.5 μm 7.5μm. By setting the area of ​​the second opening K2 to be relatively large, more ambient light passes through the second opening K2 in the application, and the corresponding light sensor can receive more ambient light, which is beneficial to improving the performance of the light sensor.

[0052] In some embodiments, the display panel includes a first row of light-emitting devices, which includes a plurality of light-emitting devices 30 arranged in the same direction. A second opening K2 is located in the first row of light-emitting devices, and the plurality of light-emitting devices 30 in the first row are of the same color. For example, such as... Figure 2 As shown, multiple light-emitting devices 30 are arranged in a row 30H in the first direction y. The row 30H includes a first row 30H1. The second opening K2 is located within the first row 30H1. The multiple light-emitting devices 30 within the first row 30H1 have the same color. Figure 2 In the embodiment, multiple light-emitting devices 30 in the first light-emitting device row 30H1 are arranged along the first direction y. Figure 2The colors of the multiple light-emitting devices 30 are not shown in the diagram. For example, the multiple light-emitting devices 30 in the first row of light-emitting devices 30H1 can emit red light. In this embodiment of the invention, a second opening K2 is provided on the first black matrix 41. The second opening K2 serves as a light-transmitting opening and is located within the first row of light-emitting devices 30H1. Optionally, the second opening K2 occupies the arrangement space of the light-emitting devices 30 within the first row of light-emitting devices 30H1, and / or occupies the arrangement space of the light-emitting devices 30 and redundant electrode groups within the first row of light-emitting devices 30H1, thereby satisfying the arrangement requirements of the second opening K2. In application, a light sensor can be set to correspond with the second opening K2. Ambient light is transmitted through the second opening K2 and received by the light sensor, which can meet the light sensor's requirements for screen transmittance. During display, the first black matrix 41 will not block the forward light emission of the light-emitting devices 30, ensuring the light emission effect of the light-emitting devices 30 and helping to reduce product power consumption.

[0053] Figure 2 In this embodiment, multiple light-emitting devices 30 in row 30H are arranged in the first direction y. In other embodiments, such as... Figure 5 As shown, multiple light-emitting devices 30 are arranged in a row of light-emitting devices 30H in the second direction x. The row of light-emitting devices 30H includes a first row of light-emitting devices 30H1. The second opening K2 is located within the first row of light-emitting devices 30H1. The multiple light-emitting devices 30 within the first row of light-emitting devices 30H1 have the same color.

[0054] For example, such as Figure 2 As shown, the second opening K2 at least partially overlaps with the light-emitting device 30 in the first direction y, and at least partially overlaps with the light-emitting device 30 in the second direction x. The first direction y and the second direction x intersect. In this embodiment of the invention, the second opening K2 is set to overlap with the light-emitting device 30 in both the first direction y and the second direction x, indicating that the second opening K2 is set in the arrangement direction of the light-emitting device 30. The second opening K2 occupies the original position where the light-emitting device 30 is arranged, rather than simply placing the second opening K2 between adjacent light-emitting devices 30. In this embodiment of the invention, the total area of ​​the first electrode 21 in the first pixel area P1 is reduced, such as reducing the number of electrode groups 20 in the first pixel area P1, so that space is left in the first pixel area P1 to arrange the second opening K2. In this way, the second opening K2 occupies at least the original position where the light-emitting device 30 is arranged, thus satisfying the arrangement requirements of the second opening K2.

[0055] For example, such as Figure 2As shown, the length of the light-emitting device 30 in the first direction y is L11, and its length in the second direction x is L21, where L11 > L21. The length of the second opening K2 in the first direction y is L12, and its length in the second direction x is L22, where L12 > L22; wherein, L22 > L21, and L12 ≥ L11. The length of the light-emitting device 30 in the first direction y is greater than its length in the second direction x, and the length of the second opening K2 in the first direction y is greater than its length in the second direction x. Both the light-emitting device 30 and the second opening K2 are approximately rectangular in shape. The second opening K2 is configured such that its length in the second direction x is greater than that of the light-emitting device 30 in the second direction x, and its length in the first direction y is not less than that of the light-emitting device 30 in the first direction y. This configuration results in the area of ​​the second opening K2 being larger than the area of ​​the light-emitting device 30. The relatively large size of the second opening K2 allows more ambient light to pass through it during application, which is beneficial for improving the performance of the light sensor.

[0056] For example, such as Figure 3 As shown, the first pixel region P1 includes two first electrodes 21, and the second pixel region P2 includes three first electrodes 21. The number of first electrodes 21 in the first pixel region P1 is less than the number of first electrodes 21 in the second pixel region P2. This embodiment reduces the total area of ​​the first electrodes 21 in the first pixel region P1 by reducing the number of first electrodes 21. A second opening K2 of the first black matrix 41 can be set in the area where the first electrodes 21 were originally located, and the second opening K2 is set in the first pixel region P1. Since the setting position of the second opening K2 does not only occupy the original non-pixel opening area, the area of ​​the second opening K2 can also be set relatively large, meeting the light intensity requirements of the light sensor in the application.

[0057] For example, Figure 6 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 6 A schematic diagram of the electrode group 20 after removing the first black matrix 41 and the light-emitting device 30 can be found in [reference needed]. Figure 3 .like Figure 6 As shown, the plurality of light-emitting devices 30 include a first color light-emitting device 31; the number of first color light-emitting devices 31 in the first pixel area P1 is less than the number of first color light-emitting devices 31 in the second pixel area P2. Figure 6 The illustration only shows a first pixel region P1 that does not include a first color light-emitting device 31, and a second pixel region P2 that includes one first color light-emitting device 31. In some embodiments, the number of first color light-emitting devices 31 in the second pixel region P2 may also be two or three.

[0058] Taking a display panel comprising three different color sub-pixels as an example, each color sub-pixel includes at least one light-emitting device, such as the first color sub-pixel including at least one first color light-emitting device 31. The number of first color light-emitting devices 31 in the first pixel area P1 can be less than the number of first color light-emitting devices 31 in the second pixel area P2. Alternatively, no first color sub-pixels can be set in the first pixel area P1, or a first color sub-pixel can be set in the first pixel area P1, and the number of first color light-emitting devices 31 in the first color sub-pixel is less than the number of first color light-emitting devices 31 included in the first color sub-pixel in the second pixel area P2.

[0059] In this embodiment of the invention, reducing the number of first-color light-emitting devices 31 within the first pixel region P1 reduces the number of first electrodes 21 connected to the first-color light-emitting devices 31 within the first pixel region P1, or reduces the area of ​​the first electrodes 21 connected to the first-color light-emitting devices 31. This reduces the total area of ​​the first electrodes 21 within the first pixel region P1. By reducing the number of first-color light-emitting devices 31 within the first pixel region P1, space can be provided within the first pixel region P1 for arranging the second opening K2. The second opening K2 occupies at least the area originally used for the light-emitting devices, and its area can be made relatively large, increasing the amount of ambient light transmitted through the second opening K2 in applications.

[0060] by Figure 6 For example, the light-emitting devices 30 in the display panel include a first-color light-emitting device 31, a second-color light-emitting device 32, and a third-color light-emitting device 33, each with a different color. The first-color light-emitting device 31 is not set within the first pixel area P1. During display, a sub-pixel rendering method can be used to display the first color; that is, the first pixel area P1 needs to borrow the first-color light-emitting devices 31 from other adjacent pixel areas for display.

[0061] Taking a display panel as an example, which includes three different color sub-pixels, each color sub-pixel includes at least one light-emitting device. Figure 6 The embodiment can also be understood as reducing the number of sub-pixels in the first pixel area P1 to reduce the total area of ​​the first electrode 21.

[0062] For example, such as Figure 6 As shown, the number of first-color light-emitting devices 31 in the first pixel area P1 is less than the number of first-color light-emitting devices 31 in the second pixel area P2. The emission wavelength of the first-color light-emitting device 31 is greater than the emission wavelength of the second-color light-emitting device 32, and the emission wavelength of the first-color light-emitting device 31 is greater than the emission wavelength of the third-color light-emitting device 33. For example, as... Figure 6As shown, each sub-pixel includes one light-emitting device. The first-color light-emitting device 31 corresponds to the first sub-pixel, the second-color light-emitting device 32 corresponds to the second sub-pixel, and the third-color light-emitting device 33 corresponds to the third sub-pixel. In adjacent 2... In the four pixel regions, the two diagonally opposite second pixel regions P2 contain first sub-pixels (i.e., the first color light-emitting device 31), while the other two diagonally opposite first pixel regions P1 contain second openings K2 and do not contain first sub-pixels. There are four pixel areas in total, sharing two first sub-pixels. That is, the second and third sub-pixels are arranged in real form, and the first sub-pixels need to be displayed using SPR (Sub-Pixel Rendering) algorithm technology.

[0063] Figure 6 The diagram illustrates a sub-pixel comprising one light-emitting device. The first-color light-emitting device 31 corresponds to the first sub-pixel, the second-color light-emitting device 32 corresponds to the second sub-pixel, and the third-color light-emitting device 33 corresponds to the third sub-pixel. Figure 6 In this embodiment, multiple first sub-pixels are arranged in a first sub-pixel column in the first direction y, multiple second sub-pixels are arranged in a second sub-pixel column in the first direction y, and multiple third sub-pixels are arranged in a third sub-pixel column in the first direction y; the first, second, and third sub-pixel columns are arranged alternately in the second direction x. The second opening K2 is located in the first sub-pixel column, meaning that the second opening K2 occupies the position originally intended for the first sub-pixel.

[0064] For example, the first color light-emitting device 31 emits red light. Considering the current power characteristics of red, green, and blue light-emitting devices, the luminous efficiency of the red light-emitting device increases more significantly with increasing current compared to the green and blue light-emitting devices. When the number of first color light-emitting devices 31 is reduced, the current of the first color light-emitting devices 31 needs to be increased to meet the brightness requirements. This results in higher luminous efficiency for the first color light-emitting devices 31, which is beneficial for reducing power consumption overall.

[0065] For example, Figure 7 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 7As shown, the multiple light-emitting devices 30 include a first-color light-emitting device 31 and a second-color light-emitting device 32. The number of first-color light-emitting devices 31 in the first pixel area P1 is less than the number of first-color light-emitting devices 31 in the second pixel area P2. Both the first pixel area P1 and the second pixel area P2 include second-color light-emitting devices 32. In the second pixel area P2, the area of ​​the first-color light-emitting device 31 is larger than the area of ​​the second-color light-emitting device 32. Reducing the number of first-color light-emitting devices 31 in the first pixel area P1 leaves space for the second opening K2 of the first black matrix 41. During display, the first pixel area P1 needs to use the first-color light-emitting devices 31 in the second pixel area P2 to emit light. Correspondingly, the area of ​​the first-color light-emitting device 31 in the second pixel area P2 is designed to increase its brightness. When the first color light-emitting device 31 uses a sub-pixel rendering method to display different pixel areas, the current of the first color light-emitting device 31 will be relatively large, and prolonged high current will accelerate device aging. In this embodiment of the invention, the area of ​​the first color light-emitting device 31 within the second pixel area P2 is increased. Therefore, when the same brightness is required, the current required by the first color light-emitting device 31 will be reduced. This slows down the aging rate of the first color light-emitting device 31, making the aging degree of different color light-emitting devices comparable, and avoiding color distortion problems after prolonged use.

[0066] Optional, such as Figure 7 As shown, the area of ​​the second opening K2 is larger than the area of ​​the first color light-emitting device 31. The second opening K2 occupies the position in the first pixel area P1 where the first color light-emitting device 31 was originally located, and the second opening K2 does not overlap with the electrode group, meaning that no electrode group is needed at the position where the second opening K2 is located. Therefore, compared to the first color light-emitting device 31, the area of ​​the second opening K2 can be set relatively larger.

[0067] For example, such as Figure 7 As shown, the plurality of light-emitting devices 30 also include a third-color light-emitting device 33, and both the first pixel region P1 and the second pixel region P2 include the third-color light-emitting device 33. In the second pixel region P2, the area of ​​the first-color light-emitting device 31 is larger than the area of ​​the third-color light-emitting device 33. Specifically, the first-color light-emitting device 31 emits red light, while the second-color light-emitting device 32 and the third-color light-emitting device 33 emit green light and blue light, respectively.

[0068] For example, such as Figure 2As shown, multiple light-emitting devices 30 are arranged in a first direction y and a second direction x, with the first direction y and the second direction x intersecting each other. The distance from the second opening K2 in the first direction y to its adjacent light-emitting device 30 is a first distance d1, and the distance from the second opening K2 in the second direction x to its adjacent light-emitting device 30 is a second distance d2. The first distance d1 is greater than the second distance d2. It should be noted that the distances mentioned in this embodiment refer to the minimum spacing between two structures. Figure 3 As can be seen, multiple second electrodes 22 are interconnected in the second direction x to form a common electrode 22c, and the first electrode 21 is located between adjacent common electrodes 22c in the first direction y. The second electrode 22 can be a cathode electrode, and the first electrode 21 can be an anode electrode. In this embodiment of the invention, the first distance d1 is set to be greater than the second distance d2, so the second opening K2 is set within the first light-emitting device row 30H1 extending along the first direction y. The second opening K2 occupies the position where the light-emitting device was originally set in the first light-emitting device row 30H1, so that the area of ​​the second opening K2 can be set relatively large, so that the amount of ambient light transmitted through the second opening K2 is large enough to meet the light quantity requirements of the light sensor.

[0069] For example, such as Figure 3 As shown, multiple second electrodes 22 are interconnected in the second direction x to form a common electrode 22c, and multiple first electrodes 21 are disposed between adjacent common electrodes 22c in the first direction y. The first direction y and the second direction x intersect each other. Figure 3 This is a top view of the display panel, which can be understood as being parallel to the projection direction of the orthographic projection onto the plane containing the substrate. Therefore, in the top view, the second opening K2 coincides with its orthographic projection onto the plane containing the substrate. Figure 3 It can be seen that the orthographic projection of the second opening K2 onto the plane where the substrate is located lies between the orthographic projections of the common electrode 22c adjacent to it in the first direction y onto the plane where the substrate is located.

[0070] In this embodiment of the invention, the electrode group 20 includes a first electrode 21 and a second electrode 22 arranged opposite to each other. The first electrode 21 and the second electrode 22 in the electrode group 20 are used to couple with the light-emitting device. Therefore, the arrangement of the first electrode 21 and the second electrode 22 determines the arrangement of the light-emitting device in the display panel. Combined with... Figure 2 and Figure 3 In this embodiment, the arrangement of the first electrode 21 and the second electrode 22 is designed such that multiple light-emitting devices 30 are arranged along the second direction x and multiple light-emitting devices are arranged along the first direction y. In this embodiment, the light-emitting devices in the first pixel area P1 and the second pixel area P2 are both arranged along the second direction x.

[0071] In accordance with the arrangement of the second opening K2 in this embodiment of the invention, the second opening K2 does not overlap with the electrode group 20 in the direction perpendicular to the plane of the substrate. Figure 3 It can be seen that the second opening K2 is located between the adjacent common electrodes 22c in the first direction y. Optionally, the area of ​​the second opening K2 is larger than the area of ​​the first electrode 21. In application, the area of ​​the second opening K2 can be set as large as possible while ensuring that the second opening K2 does not overlap with the first electrode 21 or the second electrode 22. This is beneficial to increasing the amount of ambient light transmitted through the second opening K2.

[0072] For example, Figure 8 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 8 As shown, multiple second electrodes 22 are interconnected in the second direction x to form a common electrode 22c, and multiple first electrodes 21 are disposed between adjacent common electrodes 22c in the first direction y. The orthographic projection of the second opening K2 onto the plane of the substrate lies between the orthographic projections of adjacent common electrodes 22c in the first direction y onto the plane of the substrate. Specifically, two adjacent common electrodes 22c in the first direction y include a first notch C1 and a second notch C2 disposed opposite to each other. As can be seen in the top view, the second opening K2 is partially surrounded by the first notch C1 and the second notch C2. This arrangement allows the second opening K2 to further occupy some of the space originally occupied by the common electrodes 22c, thereby further increasing the area of ​​the second opening K2.

[0073] For example, such as Figure 3 As shown, the first pixel region P1 includes two first electrodes 21 arranged in the second direction x; the second pixel region P2 includes three first electrodes 21 arranged in the second direction x. That is, the number of first electrodes 21 in the first pixel region P1 is less than the number of first electrodes 21 in the second pixel region P2. Furthermore, if the arrangement of the first electrodes 21 in the first pixel region P1 and the second pixel region P2 is the same, then the arrangement of the light-emitting devices in the two pixel regions is the same. Combined with... Figure 2 As shown, the first pixel area P1 includes two light-emitting devices 30, and the second pixel area P2 includes three light-emitting devices 30. The number of light-emitting devices 30 in the first pixel area P1 is less than the number of light-emitting devices 30 in the second pixel area P2. A second opening K2 is provided in the first pixel area P1, and the second opening K2 occupies at least the positions where the light-emitting devices were originally located in the first pixel area P1.

[0074] For example, Figure 9 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 10 To remove Figure 9 A schematic diagram of the first black matrix and the light-emitting device. Figure 10Although the first black matrix 41 is not shown, dashed lines are used to indicate the positions of the first opening K1 and the second opening K2 when the first black matrix 41 is present, in order to clearly illustrate the overlap between the opening and the electrode group 20. Figure 9 and Figure 10 The display panel includes a first pixel area P1 and a second pixel area P2 of equal area. The second opening K2 of the first black matrix 41 is located in the first pixel area P1. Multiple electrode groups include an in-situ electrode group 20-1 and a redundant electrode group 20-2; both the in-situ electrode group 20-1 and the redundant electrode group 20-2 include a first electrode 21 and a second electrode 22. The redundant electrode group 20-2 is arranged in conjunction with the in-situ electrode group 20-1, and the redundant electrode group 20-2 and its corresponding in-situ electrode group 20-1 share the first electrode 21. When a defect is found in the light-emitting device 30 coupled to the in-situ electrode group 20-1 during the lighting test, a light-emitting device 30 of the same color is coupled at the corresponding location in the redundant electrode group 20-2 for pixel repair. Figure 9 and Figure 10 The diagram illustrates the redundant position Wo, which is the location of the redundant electrode group 20-2. The redundant position Wo can also be understood as a reserved position for setting up a light-emitting device for repair. A first electrode 21 and a second electrode 22 are positioned opposite each other at the redundant position Wo.

[0075] Figure 10 The positions of the first opening K1 and the second opening K2 are shown. It can be seen that, along the plane perpendicular to the substrate, the in-situ electrode group 20-1 at least partially overlaps with the first opening K1, and at least partially, the redundant electrode group 20-2 does not overlap with the first opening K1. Specifically, when there is no light-emitting device 30 coupled to the location of the redundant electrode group 20-2, the redundant electrode group 20-2 does not overlap with the first opening K1. Figure 9 The illustration shows the case where the redundant electrode group 20-2 does not overlap with the first opening K1. When a light-emitting device 30 is coupled at the position of the redundant electrode group 20-2, the redundant electrode group 20-2 overlaps with the first opening K1. That is, when using the redundant bit Wo to repair the defective pixel, the first opening K1 needs to expose the light-emitting device 30 at the position of the redundant bit Wo.

[0076] like Figure 10 As shown, in the first pixel region P1 and the second pixel region P2, the first electrode 21 includes a first end D1 and a second end D2 opposite to each other in the first direction y. The first end D1 and the second electrode 22 adjacent to it in the first direction y form an in-situ electrode group 20-1, and the second end and the second electrode 22 adjacent to it in the first direction y form a redundant electrode group 20-2. The first pixel region P1 includes two first electrodes 21 arranged in the second direction x, and the second pixel region P2 includes three first electrodes 21 arranged in the second direction x. Figure 9The light-emitting device 30 includes a first-color light-emitting device 31, a second-color light-emitting device 32, and a third-color light-emitting device 33. The first pixel region P1 includes the second-color light-emitting device 32, the third-color light-emitting device 33, and a second opening K2. The second pixel region P2 includes the first-color light-emitting device 31, the second-color light-emitting device 32, and the third-color light-emitting device 33. Each first electrode 21 is schematically coupled to a light-emitting device of one color.

[0077] In this embodiment of the invention, a redundant electrode group 20-2 is provided, which shares a first electrode 21 with its corresponding in-situ electrode group 20-1. The first pixel region P1 includes two first electrodes 21 arranged in the second direction x, and the second pixel region P2 includes three first electrodes 21 arranged in the second direction x. This embodiment reduces the total area of ​​the first electrodes 21 in the first pixel region P1 by reducing the number of first electrodes 21, thereby leaving space for the second opening K2 of the first black matrix 41 within the first pixel region P1. Essentially, the second opening K2 occupies part of the positions of the in-situ electrode group 20-1 and the redundant electrode group 20-2 in the first pixel region P1, or part of the positions of the light-emitting device 30 and the reserved positions for repair light-emitting devices within the first pixel region P1, allowing the area of ​​the second opening K2 to be relatively large. Furthermore, the redundant electrode group enables the repair of defective pixels through detection, reducing the generation of waste chips and lowering costs.

[0078] For example, in Figure 9 In this embodiment, a sub-pixel is illustrated by including one light-emitting device. The first color light-emitting device 31 corresponds to the first sub-pixel, the second color light-emitting device 32 corresponds to the second sub-pixel, and the third color light-emitting device 33 corresponds to the third sub-pixel. It can be seen that in adjacent 2... In the four pixel regions, the two diagonally opposite second pixel regions P2 contain first sub-pixels (i.e., the first color light-emitting device 31), while the other two diagonally opposite first pixel regions P1 contain second openings K2 and do not contain first sub-pixels. There are four pixel areas in total, sharing two first sub-pixels. This means the second and third sub-pixels are arranged in a real-time pattern, and the first sub-pixels need to be displayed using the SPR (Split-Return) algorithm.

[0079] In addition, Figure 9 In this embodiment, multiple first sub-pixels are arranged in a first sub-pixel column in the first direction y, multiple second sub-pixels are arranged in a second sub-pixel column in the first direction y, and multiple third sub-pixels are arranged in a third sub-pixel column in the first direction y; the first, second, and third sub-pixel columns are alternately arranged in the second direction x. Figure 9In this embodiment, a redundant bit Wo is provided in the sub-pixel. The second opening K2 is located in the first sub-pixel column, meaning that the second opening K2 occupies the position originally occupied by the light-emitting device 30 and the redundant bit Wo in the first sub-pixel.

[0080] Figure 10 This illustration shows that reducing the number of first electrodes 21 within the first pixel region P1 reduces the total area of ​​the first electrodes 21 within the first pixel region P1. The second opening K2 occupies a portion of the position of the in-situ electrode group 20-1 and a portion of the position of the redundant electrode group 20-2 in the first pixel region P1. In other embodiments, the area of ​​the first electrodes 21 within the first pixel region P1 can also be reduced, thus reducing the total area of ​​the first electrodes 21 within the first pixel region P1, and the second opening K2 can be set to occupy at least a portion of the position of the redundant electrode group 20-2 in the first pixel region P1.

[0081] For example, Figure 11 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 12 To remove Figure 11 A schematic diagram of the first black matrix and the light-emitting device. Figure 12 The dashed lines in the diagram indicate the positions of the first opening K1 and the second opening K2 when the first black matrix 41 exists. (Example) Figure 11 As shown, the first pixel region P1 and the second pixel region P2 respectively include a first color light-emitting device 31, a second color light-emitting device 32, and a third color light-emitting device 33, and a second opening K2 of a first black matrix 41 is provided in the first pixel region P1, the first opening K1 of the first black matrix 41 at least partially overlapping with the light-emitting device 30. Combined with... Figure 12 As seen above, the first opening K1 of the first black matrix 41 partially overlaps with the electrode group 20, while the second opening K2 does not overlap with the electrode group 20. The electrode group 20 includes an in-situ electrode group 20-1 and a redundant electrode group 20-2, both of which include a first electrode 21 and a second electrode 22. The area of ​​a single first electrode 21 within the first pixel region P1 is smaller than the area of ​​a single first electrode 21 within the second pixel region P2. No redundant bit Wo is provided within the first pixel region P1. In this embodiment, the second opening K2 occupies a portion of the space within the first pixel region P1 where the redundant electrode group 20-2 is located.

[0082] Figure 12 If none of the three in-situ electrode groups 20-1 within the first pixel region P1 are provided with corresponding redundant electrode groups 20-2, then the second opening K2 occupies part of the position of the three redundant electrode groups 20-2, and the area of ​​the second opening K2 is relatively large. Optionally, Figure 12The embodiment can also be adjusted so that the second opening K2 occupies part of one or two redundant electrode groups 20-2 within the first pixel area P1. For example, if the second opening K2 occupies part of two redundant electrode groups 20-2 within the first pixel area P1, then... Figure 12 Based on the embodiment, the area of ​​the second opening K2 is appropriately reduced, and a redundant electrode group 20-2 is reserved in the first pixel area P1, which will not be shown in the figure here.

[0083] For example, Figure 13 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 14 To remove Figure 13 A schematic diagram of the first black matrix and the light-emitting device. Figure 14 The dashed lines in the diagram indicate the positions of the first opening K1 and the second opening K2 when the first black matrix 41 exists. (Example) Figure 13 As shown, the first pixel region P1 includes a second color light-emitting device 32 and a third color light-emitting device 33, and the second pixel region P2 includes a first color light-emitting device 31, a second color light-emitting device 32, and a third color light-emitting device 33. The first pixel region P1 includes a second opening K2 of the first black matrix 41. Combined with... Figure 14 In this embodiment, multiple second electrodes 22 are interconnected in the second direction x to form a common electrode 22c. Multiple first electrodes 21 are disposed between adjacent common electrodes 22c in the first direction y. The first direction y and the second direction x intersect each other. The second opening K2 is located between adjacent common electrodes in the first direction y. The first pixel region P1 includes two first electrodes 21 arranged in the first direction y; the second pixel region P2 includes three first electrodes 21, wherein two first electrodes 21 are arranged in the first direction y to form an electrode pair, and the third first electrode 21 is adjacent to the electrode pair 21D in the second direction x. This embodiment sets the number of first electrodes 21 in the first pixel region P1 to be less than the number of first electrodes 21 in the second pixel region P2, thereby reducing the total area of ​​the first electrodes 21 in the first pixel region P1. This leaves space in the first pixel region P1 for the second opening K2, which occupies at least part of the space originally occupied by the light-emitting device in the first pixel region P1.

[0084] For example, in Figure 13 In this embodiment, a sub-pixel is illustrated by including one light-emitting device. The first color light-emitting device 31 corresponds to the first sub-pixel, the second color light-emitting device 32 corresponds to the second sub-pixel, and the third color light-emitting device 33 corresponds to the third sub-pixel. It can be seen that in adjacent 2... In the four pixel regions, the two diagonally opposite second pixel regions P2 contain first sub-pixels (i.e., the first color light-emitting device 31), while the other two diagonally opposite first pixel regions P1 contain second openings K2 and do not contain first sub-pixels. There are four pixel areas in total, sharing two first sub-pixels. This means the second and third sub-pixels are arranged in a real-time pattern, and the first sub-pixels need to be displayed using the SPR (Split-Return) algorithm.

[0085] In addition, Figure 13 In this embodiment, multiple first sub-pixels are arranged in a first sub-pixel column in the first direction y, and second and third sub-pixels are alternately arranged in a second sub-pixel column in the first direction y; the first and second sub-pixel columns are alternately arranged in the second direction x. Figure 13 In this embodiment, a redundant bit Wo is provided in the sub-pixel. The second opening K2 is located in the first sub-pixel column, meaning that the second opening K2 occupies the position originally occupied by the light-emitting device 30 and the redundant bit Wo in the first sub-pixel.

[0086] For example, such as Figure 14 As shown, the multiple electrode groups 20 include an in-situ electrode group 20-1 and a redundant electrode group 20-2. Both the in-situ electrode group 20-1 and the redundant electrode group 20-2 include a first electrode 21 and a second electrode 22 arranged opposite to each other. The redundant electrode group 20-2 is arranged in conjunction with the in-situ electrode group 20-1, and the redundant electrode group 20-2 and its corresponding in-situ electrode group 20-1 share the first electrode 21. Figure 13 and Figure 14 The diagram illustrates the redundant position Wo, which is the location of the redundant electrode group 20-2. The redundant position Wo can also be understood as the reserved position for setting up a light-emitting device for repair. Figure 14 The positions of the first opening K1 and the second opening K2 are also shown. It can be seen that, along the plane perpendicular to the substrate 00, the in-situ electrode group 20-1 overlaps at least partially with the first opening K1, and the redundant electrode group 20-2 does not overlap with the first opening K1.

[0087] In the first pixel area P1, the first electrode 21 includes a third end D3 and a fourth end D4 opposite to each other in the second direction x. The third end D3 and the second electrode 22 adjacent to it in the first direction y form an in-situ electrode group 20-1, and the fourth end D4 and the second electrode 22 adjacent to it in the first direction y form a redundant electrode group 20-2.

[0088] In the second pixel region P2, the first electrode 21 in the electrode pair 20D includes a third end D3 and a fourth end D4 opposite to each other in the second direction x. The third end D3 and the second electrode 22 adjacent to it in the first direction y form an in-situ electrode group 20-1, and the fourth end D4 and the second electrode 22 adjacent to it in the first direction y form a redundant electrode group 20-2. The third first electrode 21 includes a first end D1 and a second end D2 opposite to each other in the first direction y. The first end D1 and the second electrode 22 adjacent to it in the first direction y form an in-situ electrode group 20-1, and the second end D2 and the second electrode 22 adjacent to it in the first direction y form a redundant electrode group 20-2.

[0089] The arrangement of light-emitting devices 30 within the pixel area and Figure 14 This is related to the arrangement of the first electrode 21 and the second electrode 22. Combined with... Figure 13 In the first pixel area P1, the second color light-emitting device 32 and the third color light-emitting device 33 are arranged in the first direction y, and the second color light-emitting device 32 and the third color light-emitting device 33 are respectively provided with redundant bits Wo; in the second pixel area P2, the second color light-emitting device 32 and the third color light-emitting device 33 are arranged in the first direction y, the first color light-emitting device 31, the second color light-emitting device 32, and the third color light-emitting device 33 are adjacent in the second direction x, and the three light-emitting devices are respectively provided with redundant bits Wo.

[0090] Figure 13 and Figure 14 In this embodiment, a redundant electrode group 20-2 is provided. The redundant electrode group 20-2 and its corresponding in-situ electrode group 20-1 share the first electrode 21, and the number of first electrodes 21 in the first pixel area P1 is less than the number of first electrodes 21 in the second pixel area P2. By reducing the number of first electrodes 21 in the first pixel area P1, the total area of ​​the first electrodes 21 in the first pixel area P1 is reduced, thereby leaving space in the first pixel area P1 for arranging the second opening K2 of the first black matrix 41. The second opening K2 occupies part of the position of the in-situ electrode group 20-1 and part of the position of the redundant electrode group 20-2 in the first pixel area P1, which allows the area of ​​the second opening K2 to be relatively large. Furthermore, the redundant electrode group 20-2 can repair defective pixels through detection, reducing the generation of waste chips and lowering costs.

[0091] contrast Figure 10 and Figure 14 In the examples, the difference between the two embodiments lies in the setting position of the redundant bit Wo. Figure 10 In this embodiment, the in-situ electrode group 20-1 and its corresponding redundant electrode group 20-2 are adjacent in the first direction y. Combined with... Figure 9 and Figure 10It can be seen that when no light-emitting device is coupled to the redundant bit Wo corresponding to the redundant electrode group 20-2, the redundant bits Wo in the first pixel area P1 and the second pixel area P2 are arranged along the second direction x. And... Figure 14 In this embodiment, the in-situ electrode group 20-1 and its corresponding redundant electrode group 20-2 of the second color light-emitting device 32 are adjacent in the second direction x; the in-situ electrode group 20-1 and its corresponding redundant electrode group 20-2 of the third color light-emitting device 33 are adjacent in the second direction x; and the in-situ electrode group 20-1 and its corresponding redundant electrode group 20-2 of the first color light-emitting device 31 are adjacent in the first direction y. For example,... Figure 6 For example, the display panel includes a first repeating unit Y1, which includes two first pixel areas P1 and two second pixel areas P2. The two first pixel areas P1 are located diagonally opposite each other in the first repeating unit Y1. This arrangement allows the pixel areas in the display panel to be arranged relatively regularly. For instance, if the first pixel area P1 does not include the first color light-emitting device 31, the other two color devices in the first pixel area P1 need to borrow the first color light-emitting device 31 in other pixel areas for display. The regular arrangement of the pixel areas helps to improve the overall display effect of sub-pixel rendering. In addition, a second opening K2 of the first black matrix 41 is provided in the first pixel area P1. The second opening K2, as a light-transmitting opening, affects the reflectivity of the local area to ambient light, while the regular arrangement of the pixel areas helps to improve the overall reflectivity uniformity of the display panel.

[0092] Figure 6 This illustrates the locations of the four first repeating units Y1. It can be understood that, as... Figure 11 , Figure 13 The embodiments also illustrate the locations of the four first repeating units Y1.

[0093] For example, such as Figure 11 and Figure 12 As shown, the number of first electrodes 21 in the first pixel region P1 is equal to the number of first electrodes 21 in the second pixel region P2; the area of ​​at least one first electrode 21 in the first pixel region P1 is smaller than the area of ​​the first electrode 21 in the second pixel region P2. By reducing the area of ​​a single first electrode 21 in the first pixel region P1, the total area of ​​the first electrodes 21 in the first pixel region P1 is reduced.

[0094] For example, Figure 15 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 15 As shown, the first pixel area P1 includes three types of light-emitting devices 30, the second pixel area P2 includes three types of light-emitting devices 30, and the first pixel area P1 includes a second opening K2 with a first black matrix 41. Figure 15The embodiment may also reduce the total area of the first electrodes 21 in the first pixel region P1 by reducing the area of at least one first electrode 21 in the first pixel region P1, so as to leave space for arranging the second opening K2 in the first pixel region P1.

[0095] As shown in Figure 15 , the plurality of light emitting devices 30 include a first color light emitting device 31, a second color light emitting device 32 and a third color light emitting device 33 with different colors from each other. In the first pixel region P1 and the second pixel region P2, the first color light emitting device 31 and the second color light emitting device 32 are arranged along the second direction x, the third color light emitting device 33 is arranged in a staggered manner with the first color light emitting device 31 and the second color light emitting device 32 along the first direction y, and the first direction y intersects with the second direction x; "staggered arrangement" means that the third color light emitting device 33 and the first color light emitting device 31 are at least partially non-overlapping in the first direction y, the third color light emitting device 33 and the second color light emitting device 32 are at least partially non-overlapping in the first direction y, and the third color light emitting device 33 and the first color light emitting device 31, the second color light emitting device 32 are at least partially non-overlapping in the second direction x. The three light emitting devices 30 in the first pixel region P1 and the second pixel region P2 are roughly arranged in a triangular shape. Wherein, in the first pixel region P1, the two second openings K2 are respectively located on both sides of the third color light emitting device 33 in the second direction x. The third color light emitting device 33 is any one of a red light emitting device, a green light emitting device, and a blue light emitting device. In the embodiment of the present invention, both the first pixel region P1 and the second pixel region P2 include light emitting devices of three colors, the number of the first electrodes 21 in the two pixel regions is equal, and the total area of the first electrodes 21 in the first pixel region P1 can be reduced by reducing the area of at least one first electrode 21 in the first pixel region P1.

[0096] Optionally, redundant bits (that is, the setting position of the redundant electrode group) are provided in the display panel, and the area of the first electrodes 21 responding in the first pixel region P1 can be reduced by reducing the number of redundant bits in the first pixel region P1.

[0097] For example, as shown in Figure 15 , the display panel includes a second repeating unit Y2, and the second repeating unit Y2 includes a first pixel region P1 and a second pixel region P2 adjacent to each other in the first direction y; the adjacent second openings K2 in the second repeating units Y2 adjacent in the second direction x are communicated with each other. Figure 15 Eight second repeating units Y2 arranged in an array are schematically illustrated. Figure 15The second opening K2 within the first pixel region P1 is illustrated as a semi-circle. When adjacent second openings K2 within adjacent second repeating units Y2 in the second direction x are connected, the two second openings K2 form a large circular opening, which effectively increases the area of ​​a single second opening K2. In this embodiment of the invention, the area of ​​a single second opening K2 is larger, resulting in greater light transmission through the second opening K2, thus meeting the light intensity requirements of the light sensor in applications. Furthermore, the second repeating unit Y2 in the display panel allows for a relatively regular arrangement of pixel regions. The second opening K2 within the first pixel region P1, which is a first black matrix 41, affects the reflectivity of local areas to ambient light, while the regular arrangement of pixel regions helps improve the overall reflectivity uniformity of the display panel.

[0098] Figure 16 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 16 The arrangement of light-emitting devices and Figure 15 same, Figure 16 It divides the display area according to a different pixel division method. For example... Figure 16 As shown, the horizontal and vertical dotted lines divide the area into multiple pixel regions P′. Each pixel region P′ includes a first color light-emitting device 31, a second color light-emitting device 32, and a third color light-emitting device 33 (composed of two halves of the third color light-emitting device 33). Figure 16 This is equivalent to setting the second opening K2 at the intersection of the four pixel regions P′.

[0099] Figure 17 This is a schematic diagram illustrating the principle of setting the second opening in an embodiment of the present invention. Figure 17 Using the second opening K2 as a circle for illustration, it shows... Figure 15 and Figure 16 The principle behind this second opening K2 having a large area.

[0100] Figure 17 (a) illustrates that each pixel region P′ has an opening K′, which serves as a transparent area. The edge of the opening K′ on the black matrix needs to be offset by a certain size b relative to the edge of the opening in the underlying metal layer, so that the edge of the opening K′ in the black matrix covers the edge of the opening in the metal layer. Assume... Figure 17 (a) The diameter of the metal layer opening D = 10 μm and the size offset b = 1.5 μm are 153.9 μm2.

[0101] Figure 17 (b) illustrates setting a large opening K' at the intersection of the four pixel regions P', assuming Figure 17 (b) The total area of ​​the large opening in the metal layer below the opening K′ is Figure 17 the total area of the four openings in the metal layer in (a), and the dimension offset b remains unchanged at 1.5 μm, then Figure 17 the area of the large opening K' of the black matrix in (b) is approximately 226.9 μm². Under the condition that the total area of the openings in the metal layer remains unchanged, Figure 17 compared with (b) Figure 17 in (a), the opening area of the black matrix is increased by approximately 47%. It can be seen that the solution of the present invention Figure 16 embodiment in which the second opening K2 is arranged at the intersection of the four pixel regions P' can greatly increase the area of the second opening K2. While Figure 15 the embodiment and Figure 16 the embodiment only differ in the region division manner, with the actual arrangement manner being the same, Figure 15 the embodiment can also make the second opening K2 have a relatively large area, increasing the amount of ambient light transmitted through the second opening K2.

[0102] Figure 15 and Figure 16 the embodiment only illustrates the shape of the second opening K2 as a circle. Under the condition that the arrangement space is satisfied, the shape of the second opening K2 may also be other polygonal shapes such as a hexagon, a square, and a rhombus. The second opening K2 may be a regular figure or an irregular figure.

[0103] For example, Figure 18 is a schematic diagram of another display panel provided by an embodiment of the present invention. As shown in Figure 8 , both the first pixel region P1 and the second pixel region P2 include a first color light-emitting device 31, a second color light-emitting device 32, and a third color light-emitting device 33; in the first pixel region P1 and the second pixel region P2, the three light-emitting devices 30 are roughly arranged in a triangular shape. Wherein, in the first pixel region P1, the two second openings K2 are respectively located on both sides of the third color light-emitting device 33 in the second direction x. Through the above Figure 9 and Figure 10 description of the in-situ electrode group 20-1 and the redundant electrode group 20-2 in the embodiment, it can be understood that the redundant bit Wo is the position where the redundant electrode group 20-2 is located, Figure 18 a plurality of redundant bits Wo are schematically shown therein. Figure 18 the in-situ electrode group 20-1 and the redundant electrode group 20-2 as illustrated in Figure 10 are required to be arranged in the embodiment. One end of the first electrode 21 and the adjacent second electrode 22 form the in-situ electrode group 20-1, and the other end and the adjacent second electrode 22 form the redundant electrode group 20-2; in the direction perpendicular to the plane where the substrate 00 is located, the in-situ electrode group 20-1 at least partially overlaps with the first opening K1, and at least part of the redundant electrode group 20-2 does not overlap with the first opening K1.

[0104] Figure 18 The redundant bit Wo therein represents the position of the redundant electrode group 20-2. It can be seen that the first color light-emitting device 31 in the first pixel region P1 and the first color light-emitting device 31 in the second pixel region P2 are adjacent in the first direction y, and share the redundant bit Wo located in the second pixel region P2 (i.e., share the redundant electrode group 20-2); the second color light-emitting device 32 in the first pixel region P1 and the second color light-emitting device 32 in the second pixel region P2 are adjacent in the first direction y, and share the redundant bit Wo located in the second pixel region P2 (i.e., share the redundant electrode group 20-2); the third color light-emitting device 33 in the first pixel region P1 and the third color light-emitting device 33 in the second pixel region P2 are adjacent in the first direction y, and share the redundant bit Wo located in the first pixel region P1 (i.e., share the redundant electrode group 20-2). In this embodiment, the light-emitting devices of the same color in the first pixel region P1 and the second pixel region P2 are arranged to share the redundant bit Wo, which can reduce the number of redundant electrode groups disposed in the first pixel region P1, thereby reducing the area of a single first electrode in the first pixel region P1, reducing the total area of the first electrodes in the first pixel region P1, and leaving space in the first pixel region P1 for arranging the second opening K2 of the first black matrix 41.

[0105] In another embodiment, Figure 19 is a schematic diagram of another display panel provided by an embodiment of the present invention. As shown in Figure 19 the figure, each of the first pixel region P1 and the second pixel region P2 includes a first color light-emitting device 31, a second color light-emitting device 32 and a third color light-emitting device 33; the three light-emitting devices 30 in the first pixel region P1 and the second pixel region P2 are roughly arranged in a triangular shape. In the first pixel region P1, the two second openings K2 are respectively located on both sides of the third color light-emitting device 33 in the second direction x. The second pixel region P2 is provided with three redundant bits Wo corresponding to the three light-emitting devices, and no redundant bit Wo is disposed in the first pixel region P1, thereby reducing the area of a single first electrode in the first pixel region P1, reducing the total area of the first electrodes in the first pixel region P1, and leaving space in the first pixel region P1 for arranging the second opening K2 of the first black matrix 41.

[0106] For example, Figure 20 is a schematic diagram of another display panel provided by an embodiment of the present invention, Figure 21 is a schematic cross-sectional view at the position of tangent line B-B' Figure 20 . Figure 20 The illustration is made by adding a second black matrix on the basis of the above Figure 9 embodiment. In conjunction with Figure 20 and Figure 21The display panel includes a first black matrix 41 and a second black matrix 42, with the second black matrix 42 located on the side of the first black matrix 41 furthest from the substrate 00. The first black matrix 41 includes a first opening K1 and a second opening K2, and the second black matrix 42 includes a third opening K3 and a fourth opening K4. Along the direction e perpendicular to the plane of the substrate 00, the third opening K3 is connected to the electrode group 20 (see above). Figure 3 (For illustrative purposes only) at least partially overlap. Figure 21 Only the first electrode 21 in the electrode group 20 is shown in the figure. Part of the third opening K3 overlaps with the first opening K1, and part of the third opening K3 does not overlap with the first opening K1. The fourth opening K4 overlaps with the second opening K2. A color filter unit 50 is provided in the third opening K3.

[0107] In this embodiment of the invention, a second black matrix 42 is formed above the first black matrix 41. The fourth opening K4 of the second black matrix 42 overlaps with the second opening K2 of the first black matrix 41. Part of the third opening K3 of the second black matrix 42 overlaps with the first opening K1, while part of the third opening K3 does not overlap with the first opening K1. The double-layer black matrix design can further reduce the reflectivity to ambient light. In some embodiments of the invention, the electrode group 20 includes an in-situ electrode group 20-1 and a redundant electrode group 20-2. The in-situ electrode group 20-1 is coupled to the light-emitting device 30, and the redundant electrode group 20-2 is configured in conjunction with the in-situ electrode group 20-1. The redundant electrode group 20-2 is used to repair pixels when there is a defect in the light-emitting device 30 at the location of the in-situ electrode group 20-1.

[0108] During the manufacturing of the display panel, after the coupling process between the light-emitting device 30 and the pixel circuit 10, a lighting test is performed on the display panel. If a device fails to light up during the lighting test, a new light-emitting device is fixed to the corresponding redundant electrode group 20-2 for repair. After the repair process, a first black matrix 41 is manufactured. The first black matrix 41 has a first opening K1 formed at the location where the light-emitting device 30 is located. It can be understood that when the redundant electrode group 20-2 is used to repair defects, a light-emitting device is coupled to the location of the redundant electrode group 20-2, and therefore, a first opening K1 is also provided above the redundant electrode group 20-2. Figure 21 The diagram illustrates a scenario where no light-emitting device 30 is installed at the location of the redundant electrode group 20-2. In this case, the redundant electrode group 20-2 at that location is covered by the first black matrix 41. A second black matrix 42 is fabricated after the first black matrix 41 is fabricated, followed by the color filter unit 50. The fourth opening K4 of the second black matrix 42 overlaps with the second opening K2 of the first black matrix 41, a portion of the third opening K3 overlaps with the first opening K1, and a portion of the third opening K3 does not overlap with the first opening K1. Figure 21The diagram illustrates that a light-emitting device 30 is set at the position of the redundant electrode group 20-2. In this case, the first opening K1 is not set at the position, and the third opening K3 partially overlaps with the redundant electrode group 20-2 but does not overlap with the first opening K1.

[0109] In this embodiment of the invention, the second black matrix 42 has an opening reserved for the redundant electrode group 20-2. That is, part of the third opening K3 overlaps with the original electrode group 20-1, and part of the third opening K3 overlaps with the redundant electrode group 20-2. When manufacturing the second black matrix 42, there is no need to consider different settings for redundant positions coupled to light-emitting devices and redundant positions not coupled to light-emitting devices, which simplifies the manufacturing process of the second black matrix 42.

[0110] For example, such as Figure 21 As shown, the display panel includes a first transparent layer 61 and a second transparent layer 62. The first transparent layer 61 is located between the first black matrix 41 and the second black matrix 42, and the material of the first transparent layer 61 is filled in the second opening K2. The second transparent layer 62 is located on the side of the second black matrix 42 away from the first black matrix 41, and the material of the second transparent layer 62 is filled in the fourth opening K4. Filling the second opening K2 and the fourth opening K4 with transparent materials respectively ensures the transmittance at the location of the second opening K2. Moreover, the first transparent layer 61 can act as a planarization layer so that the second black matrix 42 can be fabricated on a flat substrate, and the second transparent layer 62 can act as a planarization layer so that the film layer above it, such as the touch layer 63, can be fabricated on a flat substrate. Figure 21 The diagram shows a touch layer 63 and a cover plate 64 disposed on the second black matrix 42.

[0111] In some embodiments, the display panel includes a display area, and at least one first pixel area P1 and at least one second pixel area P2 form a repeating unit, which is repeatedly arranged within the display area. For example, the repeating unit may include, for instance,... Figure 6 The schematic diagram shows the first repeating unit Y1. The repeating unit Y1 is arranged repeatedly within the display area, enabling a relatively regular arrangement of pixel areas in the display panel. For example, if the first pixel area P1 does not include the first color light-emitting device 31, the other two color devices in the first pixel area P1 need to borrow the first color light-emitting device 31 from other pixel areas for display. This regular arrangement of pixel areas helps improve the overall display effect of sub-pixel rendering. Furthermore, a second opening K2 of the first black matrix 41 is provided within the first pixel area P1. This second opening K2, as a light-transmitting opening, affects the reflectivity of local areas to ambient light, while the regular arrangement of pixel areas helps improve the overall reflectivity uniformity of the display panel.

[0112] For example, Figure 22 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 22This indicates a partial location of the display area. For example... Figure 22 As shown, the display area includes a first area AA1 and a second area AA2. The first area AA1 includes multiple first pixel areas P1 and multiple second pixel areas P2, and the second area AA2 includes multiple second pixel areas P2. The first black matrix 41 includes a first portion 411 and a second portion 412. The first portion 411 is located in the first area AA1, and the second portion 412 is located in the second area AA2. The reflectivity of the first portion 411 is greater than that of the second portion 412. In this embodiment of the invention, the first pixel area P1 includes a second opening K2 of the first black matrix 41. The second opening K2 serves as a light-transmitting opening, affecting the reflectivity of the panel to ambient light. The second pixel area P2 does not include the second opening K2, so the reflectivity of the second pixel area P2 to ambient light is greater than that of the first pixel area P1. When the pixel arrangement of the first area AA1 and the second area AA2 is differentiated, the reflectivity of the first part 411 in the first area AA1 is set to be larger, which can compensate for the influence of the second opening K2 in the first area AA1 on the reflectivity, thereby balancing the difference in the reflectivity of the first area AA1 and the second area AA2 to ambient light and improving the overall reflectivity uniformity of the display area.

[0113] Optionally, the first portion 411 and the second portion 412 of the first black matrix 41 are configured to have a difference in reflectivity. This can be achieved by adjusting the thickness of the first black matrix 41, the concentration of doped particles, the difference in refractive index between the first black matrix 41 and the transparent material above it (i.e., the side away from the substrate).

[0114] In some embodiments, the thickness of the second portion 412 is set to be less than the thickness of the first portion 411, such that the reflectivity of the first portion 411 is greater than the reflectivity of the second portion 412.

[0115] In some embodiments, the concentration of black particles doped in the second portion 412 is set to be less than the concentration of black particles doped in the first portion 411, such that the reflectivity of the first portion 411 is greater than the reflectivity of the second portion 412.

[0116] In some embodiments, the refractive index of the first portion 411 is set to differ from the refractive index of the upper transparent layer by a greater difference than the refractive index of the second portion 412 is set from the refractive index of the upper transparent layer by a greater difference, such that the reflectivity of the first portion 411 is greater than that of the second portion 412.

[0117] Based on the same inventive concept, embodiments of the present invention provide a display device. Figure 23 This is a schematic diagram of a display device provided in an embodiment of the present invention. Figure 23 A cross-sectional schematic diagram of the display device is shown. For example... Figure 23As shown, the display device includes a display panel 100 and a light sensor 200 provided in any embodiment of the present invention. Along the direction e perpendicular to the plane of the substrate 00, the light sensor 200 overlaps with the second opening K2. The structure of the display panel 100 has been described in the above embodiments and will not be repeated here. The display device provided in the embodiments of the present invention can be, for example, an electronic device with display function such as a mobile phone, tablet, computer, television, or smart wearable product.

[0118] In this embodiment of the invention, a first opening K1 and a second opening K2 are provided in the first black matrix 41 of the display panel. The first opening K1 is a pixel opening, and the second opening K2 is a light-transmitting opening. For the first pixel area P1 and the second pixel area P2 with equal areas, by reducing the total area of ​​the first electrode 21 in the first pixel area P1, space is left in the first pixel area P1 to add the second opening K2, so that the area of ​​the second opening K2 can be relatively large. The light sensor 200 is arranged to overlap with the second opening K2, and the ambient light is received by the light sensor 200 through the second opening K2, which can meet the light sensor 200's requirements for screen transmittance. Furthermore, during display, the first black matrix 41 will not block the forward light emission of the light-emitting device 30, which can ensure the light emission effect of the light-emitting device 30 and help reduce product power consumption. This embodiment of the invention optimizes the screen transmittance by adding a second opening K2 to the first black matrix 41, meets the transmittance requirements of the under-display light sensor 200, and reduces display power consumption.
