[0098] 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.

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.

[0100] It should be noted that similar labels 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.

[0101] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0102] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0103] Please see Figure 1 The display panel in the related technology includes a light-transmitting area AB and a display area AA. A photosensitive device, such as a camera, can be placed at the location corresponding to the light-transmitting area AB. Please refer to [link / reference]. Figure 2 and Figure 3 , Figure 3 The dashed arrows in the diagram represent the light emitted by the light-emitting unit 4. In the display area AA, the display panel includes an array substrate 5, an isolation structure 1 located on one side of the array substrate 5, a light-emitting unit 4 located within an isolation opening 2 formed by the isolation structure 1, and a touch layer 10 located on the side of the light-emitting unit 4 away from the array substrate 5. The touch layer 10 includes touch traces 3, and the orthographic projection of the touch traces 3 on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5. The light emitted by the light-emitting unit 4 in the display area AA is blocked by the touch traces 3 in the wide viewing angle direction, thereby reducing the brightness of the light emitted by the light-emitting unit 4 in the display area AA in the wide viewing angle direction.

[0104] Please see Figure 4 and Figure 5 , Figure 5 The dashed arrows in the diagram represent the light emitted by the light-emitting unit 4. Multiple light-transmitting openings 12 are provided on the light-transmitting area AB isolation structure 1. Non-functional traces 11 are provided on the side of the light-emitting unit 4 away from the array substrate 5 in the light-transmitting area AB. The orthographic projection of the non-functional traces 11 on the array substrate 5 only partially surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5. Part of the light emitted by the light-emitting unit 4 in the wide viewing angle direction will not be blocked by the non-functional traces 11. As a result, the light emitted by the light-emitting unit 4 located in the display area AA in the wide viewing angle direction is less than the light emitted by the light-emitting unit 4 located in the light-transmitting area AB in the wide viewing angle direction. Consequently, the brightness of the light-transmitting area AB of the display panel is greater than the brightness of the display area AA, ultimately affecting the display performance of the display panel.

[0105] In view of this, this embodiment provides a solution that can improve the reliability of the display panel. The solution provided in this embodiment will be described in detail below.

[0106] Please see Figure 6 and Figure 7 This embodiment provides a display panel, which includes a first display area AD and a second display area AC that at least partially surrounds the first display area AD. The display panel includes an array substrate 5, a pixel defining layer 6, and a light-emitting unit 4.

[0107] The array substrate 5 may include a substrate and a plurality of driving units located on one side of the substrate. Each driving unit may include one or more semiconductor switching devices. The semiconductor switching devices may be formed by the combination of multiple film layers in the array substrate 5. For example, the semiconductor switching devices may be thin-film transistors formed by the combination of multiple film layers.

[0108] The pixel defining layer 6 is located on one side of the array substrate 5, and the pixel defining layer 6 includes a plurality of spaced pixel openings 61.

[0109] At least some of the light-emitting units 4 are located within the pixel opening 61. The area of ​​the orthogonal projection of the pixel opening 61 corresponding to the at least some of the light-emitting units 4 located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthogonal projection of the pixel opening 61 corresponding to the light-emitting units 4 located in the second display area AC on the array substrate 5.

[0110] Because the pixel openings 61 corresponding to at least some of the light-emitting units 4 located in the first display area AD are reduced, the brightness of the light emitted by the light-emitting unit 4 located in the first display area AD is less than the brightness of the light emitted by the light-emitting unit 4 located in the second display area AC. This reduces the brightness of the light emitted by the light-emitting unit 4 located in the first display area AD in the wide viewing angle direction, thereby reducing the brightness difference of the light-emitting unit 4 in the first display area AD and the second display area AC in the wide viewing angle direction, and ultimately improving the display performance of the display panel.

[0111] Based on the above design, this embodiment sets the area of ​​the orthogonal projection of the pixel opening 61 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD on the array substrate 5 to be smaller than the area of ​​the orthogonal projection of the pixel opening 61 corresponding to the light-emitting units 4 located in the second display area AC on the array substrate 5. This reduces the light-emitting brightness of the light-emitting units 4 in the first display area AD from the large viewing angle, thereby reducing the brightness difference of the light-emitting units 4 in the first display area AD and the second display area AC from the large viewing angle, and thus improving the display performance of the display panel.

[0112] For some possible implementations, please refer to Figures 8-11The display panel also includes an isolation structure 1 located on one side of the array substrate 5. The isolation structure 1 has an isolation opening 2 and a light-transmitting opening 12. At least some of the light-emitting units 4 are located in the isolation opening 2, and the light-transmitting opening 12 is located in the first display area AD. A photosensitive device, such as a camera, can be set at the position corresponding to the first display area AD.

[0113] The composition and preparation of the isolation structure 1 are further described in patents PCT / CN2023 / 134518, 202310759370.2, 202310740412.8, 202310707209.0, 202311346196.5, 202311499823.9, 202310731471.9, and 202311091555.7 for reference.

[0114] In some possible implementations, please refer again. Figures 8-11 The light-emitting unit 4 is a light-emitting unit 4 of the same color. The area of ​​the orthographic projection of the pixel opening 61 corresponding to the first display area AD on the array substrate 5 is greater than the area of ​​the orthographic projection of the pixel opening 61 corresponding to the second display area AC on the array substrate 5.

[0115] Preferably, the light-emitting unit 4 includes a first light-emitting unit, and the area of ​​the orthographic projection of the isolation opening 61 corresponding to at least a portion of the first light-emitting unit located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 61 corresponding to the first light-emitting unit located in the second display area AC on the array substrate 5.

[0116] Preferably, the light-emitting unit 4 includes a second light-emitting unit, and the area of ​​the orthographic projection of the isolation opening 61 corresponding to at least a portion of the second light-emitting unit located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 61 corresponding to the second light-emitting unit located in the second display area AC on the array substrate 5.

[0117] Preferably, the light-emitting unit 4 includes a third light-emitting unit, and the area of ​​the orthographic projection of the isolation opening 61 corresponding to at least a portion of the third light-emitting unit located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 61 corresponding to the third light-emitting unit located in the second display area AC on the array substrate 5.

[0118] Preferably, along the arrangement direction of the light-emitting units 4, the size W3 of the orthogonal projection of the pixel opening 61 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is smaller than the size D1 of the orthogonal projection of the pixel opening 61 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5.

[0119] When the pixel opening 61 corresponding to the light-emitting unit 4 in the first display area AD is smaller than the pixel opening 61 corresponding to the light-emitting unit 4 in the second display area AC, the shape of the pixel opening 61 corresponding to the light-emitting unit 4 in the first display area AD is the same as the shape of the pixel opening 61 corresponding to the light-emitting unit 4 in the second display area AC. Thus, along different directions, the size of the orthographic projection of the pixel opening 61 corresponding to the light-emitting unit 4 in the first display area AD onto the array substrate 5 is smaller than the size of the orthographic projection of the pixel opening 61 corresponding to the light-emitting unit 4 in the second display area AC onto the array substrate 5.

[0120] Preferably, please see again. Figure 9 and Figure 11 Along the arrangement direction of the light-emitting units 4, the size W1 of the orthogonal projection of the pixel opening 61 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is 0.5μm-5μm smaller than the size D1 of the orthogonal projection of the pixel opening 61 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5. For example, it can be 0.5μm, 1μm, 2μm, 3μm, 4μm, 4.5μm, or 5μm, etc. By reasonably setting the difference between size W1 and size D1, that is, by reasonably setting the size of the reduction of the pixel opening 61 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD, the difference in luminous brightness of the light-emitting units 4 at a large viewing angle between the first display area AD and the second display area AC can be reduced more effectively.

[0121] In some possible implementations, please refer again. Figure 11 The light-emitting unit 4 includes a first electrode 7, a light-emitting part 8, and a second electrode 9, which are at least partially located within the isolation opening 2 and are sequentially stacked in a direction away from the array substrate 5. The second electrode 9 is electrically connected to the isolation structure 1. The display panel also includes a pixel defining layer 6 located on one side of the array substrate 5. The isolation structure 1 is located on the side of the pixel defining layer 6 away from the array substrate 5. The pixel defining layer 6 includes a plurality of pixel openings 61. At least some of the light-emitting units 4 are located within the pixel openings 61. The orthographic projection of the pixel openings 61 on the array substrate 5 is located within the orthographic projection of the isolation opening 2 on the array substrate 5.

[0122] When forming the light-emitting functional layer, the light-emitting functional layer is separated by the isolation structure 1 to form multiple spaced light-emitting parts 8. When forming the second electrode layer, the second electrode layer is separated by the isolation structure 1 to form multiple spaced second electrodes 9. The isolation structure 1 includes a conductive material, and the second electrodes 9 are electrically connected to the isolation structure 1. A first electrode 7, a light-emitting part 8, and a second electrode 9 form a light-emitting unit 4. Among them, the first electrode 7 is the anode, and the second electrode 9 is the cathode.

[0123] In some possible implementations, please refer again. Figure 9 and Figure 11The area of ​​the orthographic projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is equal to the area of ​​the orthographic projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5.

[0124] Preferably, along the arrangement direction of the light-emitting units 4, the size W2 of the orthogonal projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is equal to the size D2 of the orthogonal projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5. Setting the size W2 of the isolation opening 2 corresponding to the light-emitting units 4 located in the first display area AD and the size D2 of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC to be consistent can reduce the risk of uneven screen shutdown in the first display area AD.

[0125] In some possible implementations, please refer again. Figure 5 , Figure 9 and Figure 11 Along the arrangement direction of the light-emitting units 4, the area of ​​the orthogonal projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is smaller than the area of ​​the orthogonal projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5.

[0126] Specifically, the area of ​​the orthographic projection of the isolation opening 2 corresponding to at least a portion of the first light-emitting units located in the first display area AD onto the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 2 corresponding to the first light-emitting unit located in the second display area AC onto the array substrate 5; the area of ​​the orthographic projection of the isolation opening 2 corresponding to at least a portion of the second light-emitting units located in the first display area AD onto the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 2 corresponding to the second light-emitting unit located in the second display area AC onto the array substrate 5; and the area of ​​the orthographic projection of the isolation opening 2 corresponding to at least a portion of the third light-emitting units located in the first display area AD onto the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 2 corresponding to the third light-emitting unit located in the second display area AC onto the array substrate 5.

[0127] Preferably, along the arrangement direction of the light-emitting units 4, the size W2 of the orthographic projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is smaller than the size D2 of the orthographic projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5.

[0128] Since the size W2 of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD is reduced, the size L1 of the light-transmitting opening 12 of the first display area AD can be increased, so that the size L1 of the light-transmitting opening 12 of the first display area AD in this embodiment is larger than the size L2 of the light-transmitting opening 12 of the first display area AD in the related art, thereby increasing the transmittance of the display panel in the first display area AD.

[0129] Preferably, please see again. Figure 9 and Figure 11 Along the arrangement direction of the light-emitting units 4, the distance L3 between the orthographic projection of the edge of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 in the first display area AD on the array substrate 5 and the orthographic projection of the edge of the corresponding pixel opening 61 on the array substrate 5 is equal to the distance L4 between the orthographic projection of the edge of the isolation opening 2 corresponding to the light-emitting units 4 in the second display area AC on the array substrate 5 and the orthographic projection of the edge of the corresponding pixel opening 61 on the array substrate 5.

[0130] Simultaneously reducing the size W1 of the pixel opening 61 and the size W2 of the isolation opening 2 in the first display area AD can make the distance L3 between the first display area AD equal to the distance L4 between the second display area AC. This maintains the consistency between the distance L3 between the isolation opening 2 and the pixel opening 61 in the first display area AD and the distance L4 between the isolation opening 2 and the pixel opening 61 in the second display area AC, thereby improving the display effect of the display panel.

[0131] Preferably, please see again. Figure 9 and Figure 11 Along the arrangement direction of the light-emitting units 4, the size W2 of the orthogonal projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is 0.5μm-5μm smaller than the size D2 of the orthogonal projection of the isolation opening 2 of the light-emitting units 4 located in the second display area AC onto the array substrate 5. Thus, the size L1 of the light-transmitting opening 12 of the first display area AD in this embodiment can be 0.5μm-5μm larger than the size L2 of the light-transmitting opening 12 of the first display area AD in related technologies. For example, it can be 0.5μm, 1μm, 2μm, 3μm, 4μm, 4.5μm, or 5μm, etc. By reasonably setting and reducing the size W2 of the isolation opening 2 of the first display area AD, the size L1 of the light-transmitting opening 12 of the first display area AD can be reasonably increased. This increases the transmittance of the display panel without affecting its display effect, thereby improving the display performance of the display panel.

[0132] In some possible implementations, please refer again. Figure 10 and Figure 11The display panel also includes a touch layer 10 located on the side of the light-emitting unit 4 away from the array substrate 5. The touch layer 10 includes touch traces 3. The orthographic projection of the touch traces 3 located in the second display area AC on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5.

[0133] Please see again Figure 8 and Figure 9 The display panel also includes a non-functional trace layer located on the side of the light-emitting unit 4 away from the array substrate 5. The non-functional trace layer includes a plurality of non-functional traces 11. The non-functional traces 11 are located in the first display area AD. The plurality of non-functional traces 11 surround the light-emitting unit 4 and are spaced apart.

[0134] Multiple non-functional traces 11 surround the same light-emitting unit 4, and the multiple non-functional traces 11 surrounding the same light-emitting unit 4 are spaced apart. Multiple non-functional traces 11 surrounding different light-emitting units 4 are also spaced apart. Since the orthographic projection of the touch trace 3 of the second display area AC on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5, and the orthographic projection of the non-functional traces 11 of the first display area AD on the array substrate 5 partially surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5, the amount of light emitted from the light-emitting unit 4 of the second display area AC that is blocked by the touch trace 3 at a wide viewing angle is greater than the amount of light emitted from the light-emitting unit 4 of the first display area AD that is blocked by the non-functional traces 11 at a wide viewing angle. In this application, the size W1 of the pixel opening 61 of the first display area AD is reduced, thereby making the brightness of the first display area AD and the second display area AC of the display panel more consistent in the wide viewing angle direction.

[0135] Preferably, please see again. Figure 8 , Figure 10 and Figure 11 The orthographic projection of the touch trace 3 on the array substrate 5 is located outside the orthographic projections of the isolation opening 2 and / or the light-transmitting opening 12 on the array substrate 5. The orthographic projection of the touch trace 3 on the array substrate 5 is located between the orthographic projections of adjacent light-emitting units 4 on the array substrate 5. The isolation opening 2 and the light-transmitting opening 12 in the first display area AD are spaced apart. In this way, the touch trace 3 is less likely to block the light from the light-emitting unit 4 at a positive viewing angle, thereby improving the display effect of the display panel.

[0136] Preferably, the non-functional trace 11 is arranged on the same layer as the touch trace 3. While the touch trace 3 is forming the second display area AC, the non-functional trace 11 is also formed in the first display area AD. In this way, there is no need to set up a special process to form the non-functional trace 11, thereby reducing the cost of setting up the non-functional trace 11.

[0137] Preferably, the orthographic projection of the non-functional trace 11 on the array substrate 5 is outside the orthographic projection of the touch trace 3 on the array substrate 5. The non-functional trace 11 is not electrically connected to the touch trace 3, and the non-functional trace 11 does not transmit signals from the touch trace 3. That is, the non-functional trace and the touch trace are insulated from each other and spaced apart.

[0138] Preferably, please see again. Figure 8 and Figure 9 The orthographic projection of the non-functional trace 11 on the array substrate 5 is located outside the orthographic projections of the isolation opening 2 and / or the light-transmitting opening 12 on the array substrate 5, and the orthographic projection of the non-functional trace 11 on the array substrate 5 is located between the orthographic projections of the adjacent light-emitting units 4 on the array substrate 5. In this way, the non-functional trace 11 is less likely to block the light from the light-emitting units 4 at a positive viewing angle, thereby improving the display effect of the display panel.

[0139] For some possible implementations, please refer to Figure 12 and Figure 13 The display panel also includes a first lens layer 13 located on the side of the light-emitting unit 4 away from the array substrate 5. The first lens layer 13 includes a plurality of spaced lens units 131. The lens units 131 are located in the first display area AD. The orthographic projection of the lens units 131 on the array substrate 5 is outside the orthographic projection of the light-emitting unit 4 on the array substrate 5. The orthographic projection of the lens units 131 on the array substrate 5 covers the orthographic projection of the light-transmitting opening 12 on the array substrate 5.

[0140] Please see again Figure 13 , Figure 13 The dashed arrows in the diagram represent the light path of the light-emitting unit. The light emitted by the light-emitting unit 4 in the first display area AD illuminates the side of the lens unit 131 facing the isolation opening 2 and is reflected on the side of the lens unit 131 facing the isolation opening 2. The reflected light will illuminate the light-emitting unit 4 in the positive viewing angle direction, thereby increasing the brightness of the display panel in the positive viewing angle direction of the first display area AD and reducing the brightness in the wide viewing angle direction of the first display area AD.

[0141] Preferably, please refer to Figure 14 The display panel also includes a second lens layer 14 located on the side of the first lens layer 13 away from the array substrate 5. The refractive index of the first lens layer 13 is less than the refractive index of the second lens layer 14. The orthogonal projection of the second lens layer 14 on the array substrate 5 covers the orthogonal projection of the light-emitting unit 4 on the array substrate 5.

[0142] Please see again Figure 14 , Figure 14The dashed arrows in the diagram represent the light path of the light-emitting unit. The light emitted by the light-emitting unit 4 in the first display area AD illuminates the second lens layer 14, and then from the second lens layer 14 illuminates the side of the lens unit 131 facing the isolation opening 2. Since the refractive index of the first lens layer 13 is less than that of the second lens layer 14, total internal reflection will occur on the surface of the lens unit 131. The light after total internal reflection will illuminate the frontal viewing angle of the light-emitting unit 4, thereby increasing the brightness of the display panel in the frontal viewing angle of the first display area AD and reducing the brightness in the wide viewing angle direction of the first display area AD.

[0143] Please see Figure 15 , Figure 15 The dashed arrows in the diagram represent the optical path of the light-emitting unit. In some embodiments, the first lens layer 13 and the second lens layer 14 are both located in the second display area AC. The orthographic projection of the first lens layer 13 located in the second display area AC onto the array substrate 5 covers the orthographic projection of the light-emitting unit 4 onto the array substrate 5. The orthographic projection of the second lens layer 14 located in the second display area AC onto the array substrate 5 covers the orthographic projection of the light-emitting unit 4 onto the array substrate 5.

[0144] When the light emitted by the light-emitting unit 4 of the second display area AC shines on the junction of the first lens layer 13 and the second lens layer 14, it will be refracted. The refracted light will not be deflected too much. Therefore, the first lens layer 13 and the second lens layer 14 have little effect on the light emitted by the light-emitting unit 4 of the second display area AC in the wide viewing angle and the normal viewing angle.

[0145] In this way, the light-emitting units 4 located in the first display area AD and the second display area AC of the display panel can have more consistent light-emitting brightness at both the normal viewing angle and the wide viewing angle, thereby further improving the display uniformity of the display panel.

[0146] Preferably, please see again. Figure 14 The display panel also includes a second encapsulation layer 17 located on the side of the light-emitting unit 4 away from the array substrate 5, and a first lens layer 13 located on the side of the second encapsulation layer 14 away from the array substrate 5. The refractive index of the second encapsulation layer 17 is less than the refractive index of the first lens layer 13 and the second lens layer 14.

[0147] Preferably, please refer to Figure 16 In some embodiments, the orthographic projections of the first lens layer 13 and the second light-transmitting layer 14 onto the array substrate 5 are located outside the orthographic projection position of the second display area AC onto the array substrate 5. This allows the brightness of the light emitted by the light-emitting unit 4 of the first display area AD in the orthographic viewing direction to be more similar to the brightness of the light emitted by the light-emitting unit 4 of the second display area AC in the orthographic viewing direction.

[0148] Specifically, the refractive index of the first lens layer 13 is in the range of 1-1.5, such as 1, 1.2, 1.4 or 1.5, etc., and the refractive index of the first lens layer 13 is in the range of 1.5-2, such as 1.5, 1.7, 1.9 or 2, etc.

[0149] Preferably, both the first lens layer 13 and the second lens layer 14 are made of organic adhesive; specifically, both the first lens layer 13 and the second lens layer 14 are made of polyimide. Properly setting the refractive index and material of the first lens layer 13 and the second lens layer 14 can improve the display effect of the display panel.

[0150] In some embodiments, see Figure 17 In embodiments without isolation structure 1, Figure 16 The dashed arrows in the diagram represent the light path of the light-emitting unit. The light emitted by the light-emitting unit 4 in the first display area AD illuminates the second lens layer 14, and then from the second lens layer 14 illuminates the side of the lens unit 131 facing the isolation opening 2. Since the refractive index of the first lens layer 13 is less than that of the second lens layer 14, total internal reflection will occur on the surface of the lens unit 131. The light after total internal reflection will illuminate the frontal viewing angle of the light-emitting unit 4, thereby increasing the brightness of the display panel in the frontal viewing angle of the first display area AD and reducing the brightness in the wide viewing angle direction of the first display area AD.

[0151] In this way, the light-emitting units 4 located in the first display area AD and the second display area AC of the display panel can have more consistent light-emitting brightness at both the normal viewing angle and the wide viewing angle, thereby further improving the display uniformity of the display panel.

[0152] For some possible implementations, please refer to Figure 18 The display panel also includes a first encapsulation layer 15 located on the side of the second electrode 9 away from the array substrate 5. The first encapsulation layer 15 includes a plurality of encapsulation units 151 spaced apart. At least some of the encapsulation units 151 extend from the side of the isolation structure 1 to the side of the isolation structure 1 away from the array substrate 5. The side of the isolation structure 1 is the face of the isolation structure 1 facing the isolation opening 2. Adjacent encapsulation units 151 are spaced apart on the side of the isolation structure 1 away from the array substrate 5. There is a gap between the encapsulation unit 151 located on the side of the isolation structure 1 away from the array substrate 5 and the side of the isolation structure 1 away from the array substrate 5.

[0153] During the patterning process of the light-emitting unit 4, the first encapsulation layer 15 is disconnected at the isolation structure 1 to form an encapsulation unit 151. The encapsulation unit 151 can completely and independently encapsulate the corresponding light-emitting unit 4, thereby improving the display characteristics of the display panel.

[0154] Preferably, please refer to Figure 19The display panel also includes a second encapsulation layer 16 located on the side of the first encapsulation layer 15 away from the array substrate 5 and a third encapsulation layer 17 located on the side of the second encapsulation layer 16 away from the array substrate 5.

[0155] The materials of the first encapsulation layer 15 and the third encapsulation layer 17 both include inorganic materials, while the material of the second encapsulation layer 16 includes organic materials. The second encapsulation layer 16 and the third encapsulation layer 17 can achieve a better encapsulation effect on the light-emitting unit 4, thereby further improving the encapsulation quality of the display panel.

[0156] Preferably, please see again. Figure 18 The isolation structure 1 includes a first isolation portion 101 and a second isolation portion 102 stacked sequentially along the direction away from the array substrate 5. The orthographic projection of the side of the first isolation portion 101 away from the array substrate 5 on the array substrate 5 is located within the orthographic projection of the second isolation portion 102 on the array substrate 5.

[0157] Since the second isolation portion 102 is located on the side of the first isolation portion 101 away from the array substrate 5, and the lateral width of the second isolation portion 102 is greater than the lateral width of the first isolation portion 101, the second isolation portion 102 will disconnect the light-emitting functional layer and the second electrode layer at the isolation structure 1. In this way, the isolation structure 1 formed by the first isolation portion 101 and the second isolation portion 102 can more easily make each light-emitting unit 4 independently packaged.

[0158] Preferably, please see again. Figure 18 The second electrode 9 of the light-emitting unit 4 is electrically connected to the first isolation portion 101. The first isolation portion 101 includes a conductive material, and the second electrode 9 corresponding to the light-emitting unit 4 extends to contact the side wall of the first isolation portion 101, so as to realize the electrical connection between the second electrode 9 corresponding to the light-emitting unit 4 and the first isolation portion 101.

[0159] Please see Figure 19 The isolation structure 1 also includes a third isolation portion 103 located on the side of the first isolation portion 101 facing the array substrate 5, and the second electrode 9 of the light-emitting unit 4 is electrically connected to the third isolation portion 103. The third isolation portion 103 includes a conductive material, and the second electrode 9 corresponding to the light-emitting unit 4 extends to contact the sidewall of the third isolation portion 103, so as to realize the electrical connection between the second electrode 9 corresponding to the light-emitting unit 4 and the third isolation portion 103.

[0160] Preferably, the third isolation portion 103 is made of molybdenum metal; and / or, the first isolation portion 101 is made of aluminum metal; and / or, the second isolation portion 102 is made of titanium metal. Thus, when the isolation structure 1 isolates the second electrode layer as the second electrode 9, the second electrode 9 is more easily electrically connected to the first isolation portion 101 and / or the third isolation portion 103.

[0161] Preferably, please refer to Figure 20 The orthographic projection of the isolation structure 1 onto the array substrate 5 forms a mesh structure. This makes it easier to independently package the light-emitting unit 4.

[0162] In some possible implementations, please refer again. Figures 7-11 This application also provides a display panel including a first display area AD and a second display area AC that at least partially surrounds the first display area AD. The display panel includes an array substrate 5, an isolation structure 1, and a light-emitting unit 4.

[0163] The isolation structure 1 is located on one side of the array substrate 5. The isolation structure 1 has an isolation opening 2 and a light-transmitting opening 12, with the light-transmitting opening 12 located in the first display area AD. A photosensitive device, such as a camera, can be placed at the position corresponding to the first display area AD.

[0164] At least some of the light-emitting units 4 are located within the isolation opening 2. The area of ​​the orthographic projection of the isolation opening 2 corresponding to the at least some of the light-emitting units 4 located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthographic projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC on the array substrate 5.

[0165] Specifically, along the arrangement direction of the light-emitting units 4, the size W2 of the orthogonal projection of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 is smaller than the size D2 of the orthogonal projection of the isolation opening 2 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5.

[0166] Since the size W2 of the isolation opening 2 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD is reduced, the size L1 of the light-transmitting opening 12 of the first display area AD can be increased, so that the size L1 of the light-transmitting opening 12 of the first display area AD in this embodiment is larger than the size L2 of the light-transmitting opening 12 of the first display area AD in the related art, thereby increasing the transmittance of the display panel in the first display area AD.

[0167] Furthermore, since the isolation opening 2 corresponding to at least some of the light-emitting units 4 located in the first display area AD is reduced, the brightness of the light emitted by the light-emitting unit 4 located in the first display area AD is less than the brightness of the light emitted by the light-emitting unit 4 located in the second display area AC. This reduces the brightness of the light emitted by the light-emitting unit 4 located in the first display area AD in the wide viewing angle direction, thereby reducing the brightness difference of the light-emitting unit 4 in the first display area AD and the second display area AC in the wide viewing angle direction, and ultimately improving the display performance of the display panel.

[0168] In summary, by setting the area of ​​the orthogonal projection of the pixel opening 61 corresponding to at least a portion of the light-emitting units 4 located in the first display area AD onto the array substrate 5 to be smaller than the area of ​​the orthogonal projection of the pixel opening 61 corresponding to the light-emitting units 4 located in the second display area AC onto the array substrate 5, the luminous brightness of the light-emitting units 4 in the first display area AD at a large viewing angle can be reduced, thereby reducing the brightness difference of the light-emitting units 4 in the first display area AD and the second display area AC at a large viewing angle, and thus improving the display performance of the display panel.

[0169] For some possible implementations, please refer to Figures 7-11 and Figure 21 This application also provides a method for manufacturing a display panel, the display panel including a first display area AD and a second display area AC at least partially surrounding the first display area AD, the method comprising:

[0170] S10: Provide an array substrate 5.

[0171] The array substrate 5 may include a substrate and a plurality of driving units located on one side of the substrate. Each driving unit may include one or more semiconductor switching devices. The semiconductor switching devices may be formed by the combination of multiple film layers in the array substrate 5. For example, the semiconductor switching devices may be thin-film transistors formed by the combination of multiple film layers.

[0172] S11: A pixel defining layer 6 is formed on one side of the array substrate 5. The pixel defining layer 6 includes a plurality of spaced pixel openings 61.

[0173] S12: Prepare light-emitting units 4, at least some of the light-emitting units 4 are located in pixel openings 61. Along the arrangement direction of the light-emitting units 4, the area of ​​the orthogonal projection of the pixel openings 61 corresponding to the light-emitting units 4 located in the first display area AD on the array substrate 5 is smaller than the area of ​​the orthogonal projection of the pixel openings 61 corresponding to the light-emitting units 4 located in the second display area AC on the array substrate 5.

[0174] The display panel formed by the above method reduces the pixel opening 61 corresponding to at least some of the light-emitting units 4 located in the first display area AD. Therefore, the brightness of the light emitted by the light-emitting units 4 located in the first display area AD is less than the brightness of the light emitted by the light-emitting units 4 located in the second display area AC. This reduces the brightness of the light emitted by the light-emitting units 4 located in the first display area AD in the wide viewing angle direction, thereby reducing the brightness difference of the light-emitting units 4 in the first display area AD and the second display area AC in the wide viewing angle direction, and ultimately improving the display performance of the display panel.

This electronic device may include a device with image processing capabilities, such as a server, personal computer, laptop computer, etc. Because this electronic device includes the display panel described in this application, its display performance is higher.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
