Detailed Implementation

[0095] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0096] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0097] 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.

[0098] 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.

[0099] It should be noted that, where there is no conflict, different features in the embodiments of this application can be combined with each other.

[0100] 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 units. 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, light-emitting units 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 units 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 units 4 on the array substrate 5. The light emitted by the light-emitting units 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 units 4 in the wide viewing angle direction.

[0101] like Figure 2 When two types of touch traces overlap in the touch trace 3, for example, if the touch trace 3 includes touch receiving traces and touch transmitting traces, then the overlapping parts of the touch receiving traces and touch transmitting traces are staggered by bridging traces to avoid electrical connection between the touch receiving traces and touch transmitting traces.

[0102] Please see Figure 4 and Figure 5 , Figure 5The dashed arrows in the diagram represent the light emitted by the light-emitting units. Multiple light-transmitting openings 12 are provided on the light-transmitting isolation structure 1. Non-functional traces 11 are located on the side of the light-emitting unit 4 furthest from the array substrate 5 in the light-transmitting area AB. The orthographic projection of the non-functional traces 11 onto the array substrate 5 only partially surrounds the orthographic projection of the light-emitting unit 4 onto the array substrate 5. Thus, a portion of the light emitted by the light-emitting unit 4 in the wide viewing angle direction is not blocked by the non-functional traces 11. Consequently, the light emitted by the light-emitting unit 4 located in the display area AA in the wide viewing angle direction is less than that of the light-emitting unit 4 located in the light-transmitting area. This results in the brightness of the light-transmitting area AB of the display panel being greater than the brightness of the display area AA, ultimately affecting the display performance of the display panel.

[0103] In view of this, this embodiment provides a solution to improve the display performance of the display panel, and the solution provided in this embodiment will be described in detail below.

[0104] Please see Figures 6-8 , Figure 8 The dashed arrows in the figure represent the light rays of the light-emitting unit. 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, an isolation structure 1, a light-emitting unit 4, and non-functional traces 11.

[0105] 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.

[0106] The isolation structure 1 is located on one side of the array substrate 5. The isolation structure 1 is provided with an isolation opening 2 and a light-transmitting opening 12. The light-transmitting opening 12 is located in the first display area AD.

[0107] The first display area AD includes multiple light-transmitting openings 12. A photosensitive device, such as a camera, can be set at the position corresponding to the first display area AD.

[0108] At least some of the light-emitting units 4 are located within the isolation opening 2; the non-functional trace 11 is located on the side of the light-emitting unit 4 away from the array substrate 5, the non-functional trace 11 is located in the first display area AD, and the orthographic projection of the non-functional trace 11 on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5.

[0109] The light-emitting unit 4 includes a first light-emitting subunit 13, a second light-emitting subunit 14, and a third light-emitting subunit 15. For example, the first light-emitting subunit 13 includes a red light-emitting subunit, the second light-emitting subunit 14 includes a green light-emitting subunit, and the third light-emitting subunit 15 includes a blue light-emitting subunit.

[0110] 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.

[0111] Non-functional traces 11 do not transmit signals. The first display area AD of this application is equivalent to the light-transmitting area AB in the related art, and the second display area AC is equivalent to the display area AA in the related art. The orthographic projection of the non-functional traces 11 of the first display area AD on the array substrate 5 completely surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5. In this way, the light emitted by the light-emitting unit 4 of the first display area AD will be blocked more by the non-functional traces 11 at a wide viewing angle, thereby reducing the light emitted by the light-emitting unit 4 of the first display area AD in the wide viewing angle direction, thereby reducing the brightness of the first display area AD, and finally reducing the brightness difference between the first display area AD and the second display area AC of the display panel, improving the display uniformity of the display panel, so as to improve the display performance of the display panel.

[0112] Based on the above design, this embodiment sets the orthographic projection of the non-functional trace 11 on the array substrate 5 to completely surround the orthographic projection of the light-emitting unit 4 on the array substrate 5, which can reduce the brightness of the light-emitting unit 4 in the first display area AD at a wide viewing angle, thereby improving the display uniformity of the display panel at a wide viewing angle, improving the color shift of the display panel, and further improving the display performance of the display panel.

[0113] In one possible implementation, referring again to 8, 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.

[0114] 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.

[0115] In one possible implementation, please refer to Figures 9-10 , Figure 10 The dashed arrows in the diagram represent the light rays from the light-emitting unit. The 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 in the second display area AC onto the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 onto the array substrate 5.

[0116] Since the orthographic projection of the touch trace 3 of the second display area AC onto the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 onto the array substrate 5, the amount of light emitted by 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 basically the same as the amount of light emitted by the light-emitting unit 4 of the first display area AD that is blocked by the non-functional trace 11 at a wide viewing angle. This makes the brightness of the first display area AD and the second display area AC of the display panel more consistent.

[0117] 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.

[0118] 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.

[0119] Preferably, please see again. Figure 8 and Figure 10 The distance L1 between the orthographic projection of the non-functional trace 11 on the array substrate 5 and the orthographic projection of the pixel opening 61 of the corresponding light-emitting unit 4 on the array substrate 5 is equal to the distance L3 between the orthographic projection of the touch trace 3 located in the second display area AC on the array substrate 5 and the orthographic projection of the pixel opening 61 of the corresponding light-emitting unit 4 on the array substrate 5.

[0120] In this embodiment, the distances L1 and L3 are set to be equal, which makes the amount of occlusion of the non-functional traces 11 of the first display area AD at a wide viewing angle more similar to the amount of occlusion of the touch traces 3 of the second display area AC at a wide viewing angle, thereby further improving the display uniformity of the display panel.

[0121] Preferably, please see again. Figure 7 and Figure 9 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, and the orthographic projection of the touch trace 3 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 touch trace 3 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.

[0122] In one possible implementation, please refer to Figures 7-8 and Figure 11 The non-functional trace 11 includes a first non-functional sub-trace 111 and a second non-functional sub-trace 112. The first non-functional sub-trace 111 and the second non-functional sub-trace 112 are located in different film layers. The orthographic projection of the non-functional trace 11 on the array substrate 5 is outside the orthographic projection of the isolation opening 2 and / or the light-transmitting opening 12 on the array substrate 5. The first non-functional sub-trace 111 and the second non-functional sub-trace 112 are insulated from each other. The first non-functional sub-trace 111 is located on the side of the second non-functional sub-trace 112 closer to the array substrate 5. The pattern formed by the orthographic projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5.

[0123] Setting the non-functional trace 11 to include a first non-functional sub-trace 111 and a second non-functional sub-trace 112 of different layers makes it easier for the orthogonal projection of the non-functional trace 11 composed of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 to surround the orthogonal projection of the light-emitting unit 4 on the array substrate 5. It also makes it possible to prevent the first non-functional sub-trace 111 and the second non-functional sub-trace 112 from being electrically connected.

[0124] Preferably, please see again. Figure 7This embodiment provides a first scheme in which the pattern formed by the orthogonal projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 surrounds the orthogonal projection of the light-emitting unit 4 on the array substrate 5. The orthogonal projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 are complementary, that is, the edge of the orthogonal projection of the first non-functional sub-trace 111 on the array substrate 5 just touches the edge of the orthogonal projection of the second non-functional sub-trace 112 on the array substrate 5. In this way, the orthogonal projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 can just form a pattern surrounding the orthogonal projection of the light-emitting unit 4 on the array substrate 5.

[0125] Preferably, please see again. Figure 7 and Figure 8 The orthographic projection of the non-functional trace 11 on the array substrate 5 lies between the orthographic projections of the adjacent light-emitting unit 4 on the array substrate 5. In the first display area AD, the isolation opening 2 and the light-transmitting opening 12 are spaced apart, and the orthographic projection of the light-transmitting opening 12 on the array substrate 5 lies outside the orthographic projection of the light-emitting unit 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 unit 4 at a positive viewing angle, thereby improving the display effect of the display panel.

[0126] Preferably, please see again. Figure 7 , Figure 8 and Figure 11 The distance L2 between the orthographic projection of the first non-functional sub-line 111 on the array substrate 5 and the orthographic projection of the pixel opening 61 of the corresponding light-emitting unit 4 on the array substrate 5 is equal to the distance L4 between the orthographic projection of the second non-functional sub-line 112 on the array substrate 5 and the orthographic projection of the pixel opening 61 of the corresponding light-emitting unit 4 on the array substrate 5.

[0127] In this embodiment, the distances L2 and L4 are set to be equal, which makes the amount of light blocking of the first non-functional sub-line 111 and the second non-functional sub-line 112 of the first display area AD basically the same at a wide viewing angle, thereby improving the display uniformity of the first display area AD of the display panel.

[0128] In one possible implementation, please refer to Figures 12-14 The orthographic projection of the first non-functional sub-line 111 on the array substrate 5 surrounds the orthographic projections of the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 on the array substrate 5, and the orthographic projection of the second non-functional sub-line 112 on the array substrate 5 surrounds the orthographic projection of the second light-emitting sub-unit 14 on the array substrate 5.

[0129] This embodiment provides a second scheme in which the pattern formed by the orthographic projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5. Since the distance between the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 is relatively greater, setting the orthographic projection of the first non-functional sub-trace 111 on the array substrate 5 to surround the orthographic projections of the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 on the array substrate 5 can prevent the first non-functional sub-trace 111 surrounding the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 from being electrically connected.

[0130] Since the first non-functional sub-line 111 and the second non-functional sub-line 112 are located in different film layers, the second non-functional sub-line 112 surrounding the second light-emitting sub-unit 14 is not electrically connected to the first non-functional sub-line 111. At the same time, the first non-functional sub-line 111 and the second non-functional sub-line 112 can surround different light-emitting units 4.

[0131] In one possible implementation, please refer to Figures 15-17 The orthographic projection of the first non-functional sub-line 111 on the array substrate 5 surrounds the orthographic projection of the second light-emitting sub-unit 14 on the array substrate 5, and the orthographic projection of the second non-functional sub-line 112 on the array substrate 5 surrounds the orthographic projections of the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 on the array substrate 5.

[0132] This embodiment provides a third scheme for the pattern formed by the orthogonal projections of the first non-functional sub-trace 111 and the second non-functional sub-trace 112 onto the array substrate 5, surrounding the orthogonal projection of the light-emitting unit 4 onto the array substrate 5. Since the distance between the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 is relatively greater, setting the orthogonal projection of the second non-functional sub-trace 112 onto the array substrate 5 to surround the orthogonal projections of the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 onto the array substrate 5 allows the second non-functional sub-trace 112 surrounding the first light-emitting sub-unit 13 and the third light-emitting sub-unit 15 to be electrically disconnected.

[0133] Since the first non-functional sub-line 111 and the second non-functional sub-line 112 are located in different film layers, the second non-functional sub-line 112 surrounding the second light-emitting sub-unit 14 is not electrically connected to the first non-functional sub-line 111. At the same time, the first non-functional sub-line 111 and the second non-functional sub-line 112 can surround different light-emitting units 4.

[0134] In one possible implementation, please refer to Figure 18The display panel also includes a first encapsulation layer 16 located on the side of the second electrode 9 away from the array substrate 5. The first encapsulation layer 16 includes a plurality of encapsulation units 161 spaced apart. At least some of the encapsulation units 161 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 161 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 161 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.

[0135] During the patterning process of the light-emitting unit, the first encapsulation layer 16 is disconnected at the isolation structure 1 to form an encapsulation unit 161. The encapsulation unit 161 can completely and independently encapsulate the corresponding light-emitting unit, thereby improving the display characteristics of the display panel.

[0136] Preferably, please refer to Figure 19 The display panel also includes a second encapsulation layer 17 located on the side of the first encapsulation layer 16 away from the array substrate 5 and a third encapsulation layer 18 located on the side of the second encapsulation layer 17 away from the array substrate 5, with the non-functional trace 11 located on the side of the third encapsulation layer 18 away from the array substrate 5.

[0137] The first encapsulation layer 16 and the third encapsulation layer 18 are both made of inorganic materials, while the second encapsulation layer 17 is made of organic materials. The second encapsulation layer 17 and the third encapsulation layer 18 provide a better encapsulation effect for the light-emitting unit, thereby further improving the encapsulation quality of the display panel.

[0138] 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 encapsulate the light-emitting unit 4.

[0139] In one possible implementation, please refer 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.

[0140] 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 independently packaged.

[0141] In one possible implementation, please refer again. Figure 18 The second electrode 9 of the light-emitting unit 4 is electrically connected to the first isolation part 101; please refer again. Figure 19 And / or, the isolation structure 1 further includes a third isolation portion 103 located on the side of the first isolation portion 101 facing the array substrate 5, the second electrode 9 of the light-emitting unit 4 being electrically connected to the third isolation portion 103, the material of the third isolation portion 103 including molybdenum metal; and / or, the material of the first isolation portion 101 including aluminum metal; and / or, the material of the second isolation portion 102 including 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.

[0142] In summary, by setting the orthographic projection of the non-functional trace 11 on the array substrate 5 to the orthographic projection of the surrounding light-emitting unit 4 on the array substrate 5, this application can reduce the brightness of the light-emitting unit 4 in the first display area AD at a wide viewing angle, thereby improving the display uniformity of the display panel at a wide viewing angle, improving the color shift of the display panel, and further improving the display performance of the display panel.

[0143] In one possible implementation, please refer to Figure 6 and Figure 21 This application also provides another 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 light-emitting unit 4, and non-functional traces 11.

[0144] The light-emitting unit 4 is located on one side of the array substrate 5, and the non-functional trace 11 is located on the side of the light-emitting unit 4 away from the array substrate 5. The non-functional trace 11 is located in the first display area AD, and the orthogonal projection of the non-functional trace 11 on the array substrate 5 surrounds the orthogonal projection of the light-emitting unit 4 on the array substrate 5.

[0145] The display panel also includes a pixel defining layer 6 located on one side of the array substrate 5. The pixel defining layer 6 includes a plurality of pixel openings 61. At least a portion of the light-emitting units 4 are located within the pixel openings 61. The light-emitting units 4 include a first electrode 7, a light-emitting portion 8, and a second electrode 9, which are at least partially located within the pixel openings 61 and are sequentially stacked in a direction away from the array substrate 5.

[0146] Non-functional traces 11 do not transmit signals. The first display area AD in this application is equivalent to the light-transmitting area in related technologies, and the second display area AC is equivalent to the display area AA in related technologies. The orthographic projection of the non-functional traces 11 of the first display area AD on the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 on the array substrate 5. In this way, the light emitted by the light-emitting unit 4 of the first display area AD will be more blocked by the non-functional traces 11 at a wide viewing angle, thereby reducing the light emitted by the light-emitting unit 4 of the first display area AD in the wide viewing angle direction, thereby reducing the brightness of the first display area AD, and ultimately reducing the brightness difference between the first display area AD and the second display area AC of the display panel, improving the display uniformity of the display panel, and ultimately improving the display performance of the display panel.

[0147] In one possible implementation, please refer to Figure 22 This application also provides a method for manufacturing a display panel, the display panel including a first display area AD, the method comprising:

[0148] S10: Provide an array substrate 5.

[0149] 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.

[0150] S11: An isolation structure 1 is formed on one side of the array substrate 5. The isolation structure 1 is provided with an isolation opening 2 and a light-transmitting opening 12. The light-transmitting opening 12 is located in the first display area AD.

[0151] The first display area AD includes multiple light-transmitting openings 12. A photosensitive device, such as a camera, can be set at the position corresponding to the first display area AD.

[0152] S12: At least a portion of the light-emitting unit 4 is formed within the isolation opening 2.

[0153] The light-emitting unit 4 includes a first light-emitting subunit 13, a second light-emitting subunit 14, and a third light-emitting subunit 15. For example, the first light-emitting subunit 13 includes a red light-emitting subunit, the second light-emitting subunit 14 includes a green light-emitting subunit, and the third light-emitting subunit 15 includes a blue light-emitting subunit.

[0154] S13: A non-functional trace 11 is formed on the side of the light-emitting unit 4 away from the array substrate 5. The non-functional trace 11 is located in the first display area AD. The orthogonal projection of the non-functional trace 11 on the array substrate 5 surrounds the orthogonal projection of the light-emitting unit 4 on the array substrate 5.

[0155] Non-functional traces 11 do not transmit signals. The orthographic projection of the non-functional traces 11 of the first display area AD of the display panel formed by the method in this embodiment onto the array substrate 5 surrounds the orthographic projection of the light-emitting unit 4 onto the array substrate 5. Thus, the light emitted by the light-emitting unit 4 of the first display area AD is more blocked by the non-functional traces 11 at a wide viewing angle, thereby reducing the light emitted by the light-emitting unit 4 of the first display area AD in the wide viewing angle direction, further reducing the brightness of the first display area AD, and ultimately reducing the brightness difference between the first display area AD and the second display area AC of the display panel, improving the display uniformity of the display panel, and ultimately improving the display performance of the display panel.

[0156] In some possible implementations, this application also provides an electronic device that includes the display panel described in this application. 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 reliability is higher.

[0157] The technical features of the above embodiments can be combined in any way. 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.

[0158] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
