[0107] Therefore, the detailed description of the embodiments of the present application provided below in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0108] It should be noted that similar reference numerals and letters refer to like items throughout the accompanying drawings, and once an item is defined in one drawing, it is not necessary for it to be further defined and explained in the subsequent drawings.

[0109] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed during use, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0110] It should be noted that the different features in the embodiments of the present application can be combined with each other without conflict.

[0121] According to the manufacturing sequence of the first light emitting sub-device and the second light emitting sub-device, the embodiment ensures that, after the first light emitting sub-device and the second light emitting sub-device are manufactured, the first extension length D1 of the first edge wrapping part 9111 located at at least one side of the first light emitting sub-device is equal to the second extension length D2 of the second edge wrapping part 9112 located at at least one side of the second light emitting sub-device in the cross section perpendicular to the extension direction of the isolation structure enclosing the corresponding light emitting sub-device, that is, the distance between the front projection of the part of the second packaging part 911 corresponding to the first light emitting sub-device on the array substrate 1 towards the side of the isolation opening 6 and the front projection of the part of the second packaging part 911 corresponding to the second light emitting sub-device on the array substrate 1 away from the side of the isolation opening 6 is equal.

[0122] The cross section of the first edge wrapping part 9111 corresponding to the extension direction of the isolation structure 7 enclosing the first light emitting sub-device and the cross section of the first edge wrapping part 9111 corresponding to the extension direction of the isolation structure 7 enclosing the first light emitting sub-device can be located in the same preset direction or different preset directions. The same preset direction includes the display panel scan signal line direction, the display panel data signal line direction, the arrangement direction of each light emitting sub-device, the extension direction of the symmetry axis or center line of the light emitting device, or the direction at a certain angle with the display panel scan signal line. That is, the direction of the first edge wrapping part 9111 located in the first sub-device is consistent with the direction of the second edge wrapping part 9112 located in the second sub-device.

[0123] The different preset directions are that the direction of the first edge wrapping part 9111 located in the first sub-device is inconsistent with the direction of the second edge wrapping part 9112 located in the second sub-device.

[0124] For example, along the extension direction a of the display panel scan signal line in the display panel, the length D1 is equal to the length D2. For another example, along the extension direction b of the symmetry axis of the light emitting sub-device in the display panel, the length D1 is equal to the length D2. The direction a can be the extension direction of the scan line of the display panel in the display area, the angle between the direction b and the direction a is β, and the range of β is 0-360°, for example, β can be 60°, 90° or 120°, etc. Figure 3 Figure 3 For example, along the extension direction a of the display panel scan signal line in the display panel, the length D1 is equal to the length D2. For another example, along the extension direction b of the symmetry axis of the light emitting sub-device in the display panel, the length D1 is equal to the length D2. The direction a can be the extension direction of the scan line of the display panel in the display area, the angle between the direction b and the direction a is β, and the range of β is 0-360°, for example, β can be 60°, 90° or 120°, etc.

[0125] ​Here, the length D1 can not be absolutely equal to the length D2, as long as the difference between the length D1 and the length D2 is within a preset error range. For example, the length D1 can be considered equal to the length D2 when the length D1 is 5%-20% longer than the length D2. In addition, the extension direction of the isolation structure 7 in the cross section perpendicular to the extension direction of the isolation structure 7 surrounding the corresponding light emitting sub-device refers to the extension direction close to the side surface of the isolation opening 6. Different sections of the isolation structure 7 can have different extension directions. For example, the orthographic projection of the isolation structure 7 on the array substrate 1 has an arc-shaped section, and the extension direction of each section of the isolation structure 7 is different. In the extension direction of any section of the isolation structure 7, the isolation structure 7 has a cross section, and the first extension length D1 or the second extension length D2 is the length of a line segment in the plane of the cross section. For example, Figure 3 The direction d is the extension direction of the isolation structure 7, and the direction e is perpendicular to the extension direction of the isolation structure 7. In this way, the package unit 91 has substantially the same effect on the light emission of the first light emitting sub-device and the second light emitting sub-device, thereby improving the consistency of the light emission of the first light emitting sub-device and the second light emitting sub-device. In addition, the package effect of the light emitting sub-device is effectively ensured by setting the length of the edge wrapping part, thereby avoiding package cracks caused by subsequent processes, and finally improving the display effect of the display panel.

[0126] Based on the above design, by setting the length D1 of the first edge wrapping part 9111 and the length D2 of the second edge wrapping part 9112 to be equal, the display effect of the display panel can be improved.

[0127] In some possible implementation manners, referring to Figure 4 , the light emitting device 8 further includes a third light emitting sub-device. The second package unit 911 corresponding to the third light emitting sub-device includes a third edge wrapping part 9113. On a cross section perpendicular to the extension direction of the isolation structure 7 surrounding the third light emitting sub-device, the third edge wrapping part 9113 has a third extension length D3, and the third extension length D3 is equal to the first extension length D1 or the second extension length D2. The orthographic projection of the second package unit 911 and the first edge wrapping part 9111, the second edge wrapping part 9112, and the third edge wrapping part 9113 included therein on the array substrate 1 is located in the range of the orthographic projection of the isolation structure 7 on the array substrate 1.

[0128] The light emitting colors of the first light emitting sub-device, the second light emitting sub-device, and the third light emitting sub-device are all different. For example, the light emitting color of the first light emitting sub-device can be red, the light emitting color of the second light emitting sub-device can be green, and the light emitting color of the third light emitting sub-device can be blue.

[0129] In some possible implementation manners, referring again toFigure 4 The second encapsulation part 911 located at different sides of the same light emitting sub-device has equal length extending in a direction away from the isolation opening 6. That is, the orthographic projection of the second encapsulation part 911 on the substrate is annular, and the width of each part of the annular is the same. The length of the second encapsulation part 911 extending in a direction away from the isolation opening 6 can also be the length in a cross section perpendicular to the extending direction of the isolation structure located below the second encapsulation part 911. In this way, the light emitted by the same light emitting sub-device in different directions can be more uniform, thereby improving the display uniformity of the display panel.

[0130] Preferably, the length of the second encapsulation part 911 extending in a direction away from the isolation opening 6 ranges from 2 μm to 6 μm, for example, the distance can be 2 μm, 3 μm, 4 μm, 5 μm or 6 μm, etc. Reasonably setting the distance can make the encapsulation effect and display effect of the display panel better.

[0131] In some possible implementation manners, referring again to Figure 4 The first light emitting sub-device, the second light emitting sub-device and the third light emitting sub-device are arranged adjacently, and the encapsulation unit 91 includes a first encapsulation unit 901 located at the side of the first light emitting sub-device away from the array substrate 1, a second encapsulation unit 902 located at the side of the second light emitting sub-device away from the array substrate 1, and a third encapsulation unit 903 located at the side of the third light emitting sub-device away from the array substrate 1. The first encapsulation unit 901, the second encapsulation unit 902 and the third encapsulation unit 903 are arranged at intervals, and the second encapsulation part 9111 of the first encapsulation unit 901 and the second encapsulation part 9112 of the second encapsulation unit 902 are arranged at intervals at the side of the isolation structure 7 away from the array substrate 1.

[0132] In some possible implementation manners, referring again to Figure 4 The second encapsulation part 911 located at different sides of the same light emitting sub-device has equal length extending in a direction away from the isolation opening 6. That is, the orthographic projection of the second encapsulation part 911 on the substrate is annular, and the width of each part of the annular is the same. The length of the second encapsulation part 911 extending in a direction away from the isolation opening 6 can also be the length in a cross section perpendicular to the extending direction of the isolation structure located below the second encapsulation part 911. In this way, the light emitted by the same light emitting sub-device in different directions can be more uniform, thereby improving the display uniformity of the display panel. Figure 3 In this way, the light emitted by the same light emitting sub-device in different directions can be more uniform, thereby improving the display uniformity of the display panel, and further improving the display effect of the display panel.

[0158] Preferably, the second extension 91102 located at the side of the second light emitting sub-device close to the first light emitting sub-device is located at the side of the second extension 91102 located at the side of the first light emitting sub-device close to the second light emitting sub-device away from the array substrate 1. In this way, the second extension 91102 of the second light emitting sub-device can protect the second extension 91102 of the first light emitting sub-device, so that the second extension 91102 of the first light emitting sub-device is not easy to break in subsequent processes.

[0159] Preferably, the length L1 of the second extension 91102 located at the at least one side of the first light emitting sub-device extending away from the isolation opening 6 is equal to the length L2 of the second extension 91102 located at the at least one side of the second light emitting sub-device extending away from the isolation opening 6.

[0165] By setting the second extension 91102 of the second light emitting sub-device and the second extension 91102 of the third light emitting sub-device to completely coincide, the packaging effect of the packaging unit 91 on the third light emitting sub-device and the second light emitting sub-device can be further improved, and the second extension 91102 on the side away from the array substrate 1 can also better protect the second extension 91102 on the side close to the array substrate 1.

[0166] Preferably, the part of the first extension 91101 located at the side of the second packaging unit 902 close to the first light emitting sub-device includes a horizontal segment 911012 and an inclined segment 911011 connected to each other, and the end of the inclined segment 911011 away from the horizontal segment 911012 is connected to the second extension 91102. The first extension 91101 located at the side of the third packaging unit 903 close to the second light emitting sub-device includes a horizontal segment 911012 and an inclined segment 911011 connected to each other, and the end of the inclined segment 911011 away from the horizontal segment 911012 is connected to the second extension 91102. Specifically, the horizontal segment 911012 and the inclined segment 911011 are integrally formed.

[0167] In this way, it is more convenient to set the second extension 91102 on the side of the second light emitting sub-device close to the first light emitting sub-device to be on the side away from the array substrate 1 of the second extension 91102 located at the side of the first light emitting sub-device close to the second light emitting sub-device, and it is more convenient to set the second extension 91102 on the side of the third light emitting sub-device close to the second light emitting sub-device to be on the side away from the array substrate 1 of the second extension 91102 located at the side of the second light emitting sub-device close to the third light emitting sub-device.

[0168] Preferably, the length N3 of the third wrapping portion 9113 and the length N2 of the second wrapping portion 9112 and the length N1 of the wrapping portion 911 of the first packaging unit 901 are all the same. That is, the lengths of the second wrapping portion 9112 and the fourth wrapping portion 9114 located on different sides of the second light emitting sub-device are the same. The length M3 of the first extension portion 91101 of the third packaging unit 903 extending away from the isolation opening 6 and the length M2 of the first extension portion 91101 of the second packaging unit 902 extending away from the isolation opening 6 are the same, and the length M1 of the first extension portion 91101 of the first packaging unit 901 extending away from the isolation opening 6 and the length M2 of the first extension portion 91101 of the second packaging unit 902 extending away from the isolation opening 6 are the same. Here, the length extending away from the isolation opening 6 is the straight line length in the cross section perpendicular to the extension direction of the corresponding isolation structure 7.

[0169] In some possible embodiments, referring again to Figure 6 , the length L1 of the second extension portion 91102 located on at least one side of the first light emitting sub-device extending away from the isolation opening 6 is greater than or equal to 1.5 μm and less than or equal to 2 μm, for example, the length L1 can be 1.5 μm, 1.6 μm, 1.7 μm, 1.8 μm, 1.9 μm or 2 μm, etc. Reasonably setting the length L1 can improve the packaging effect on the first light emitting sub-device.

[0170] Preferably, the length W2 of the horizontal section 911012 of the first extension portion 91101 located on the side of the third light emitting sub-device close to the second light emitting sub-device extending away from the isolation opening 6 is equal to the length W1 of the horizontal section 911012 of the first extension portion 91101 located on the side of the second light emitting sub-device close to the first light emitting sub-device extending away from the isolation opening 6.

[0171] In the embodiment, the length W2 is not completely equal to the length W1, and the absolute value of the difference between the length W2 and the length W1 is within 10% of the length W1, which can be considered as the length W2 being equal to the length W1. In this way, the consistency of the packaging effect of the packaging unit 91 on the second light emitting sub-device and the third light emitting sub-device can be further improved.

[0172] Specifically, the length W2 of the horizontal section 911012 of the first extension portion 91101 located on the side of the third light emitting sub-device close to the second light emitting sub-device extending away from the isolation opening 6 is greater than or equal to 1 μm and less than or equal to 1.2 μm, for example, the length W2 can be 1 μm, 1.05 μm, 1.1 μm, 1.15 μm or 1.2 μm, etc. Reasonably setting the length W2 can further improve the packaging effect on the third light emitting sub-device.

[0173] Preferably, the angle β between the horizontal segment 911012 of the first extension portion 91101 located on the side of the third light-emitting sub-device close to the second light-emitting sub-device and the inclined segment 911011 is greater than or equal to 100° and less than or equal to 150°. For example, the angle β2 can be 100°, 110°, 120°, 130°, 140° or 150°, etc. Reasonable setting of the angle β2 can improve the packaging effect of the packaging unit 91 on the third light-emitting sub-device.

[0175] The second encapsulation layer 10 and the third encapsulation layer 11 can achieve a better encapsulation effect on the light-emitting device 8, thereby further improving the encapsulation quality of the display panel.

[0176] For some possible implementations, see again Figure 6 The light-emitting device 8 includes a first electrode layer, a light-emitting functional layer, and a second electrode layer stacked in sequence in a direction away from the array substrate 1. The display panel also includes a pixel defining layer 3 located on a side of the first electrode layer away from the array substrate 1. The isolation structure 7 is located on a side of the pixel defining layer 3 away from the array substrate 1. The pixel defining layer 3 includes a pixel opening 31 that exposes at least a portion of the first electrode 2. The orthographic projection of the isolation structure 7 on the array substrate 1 is located between the orthographic projections of two adjacent pixel openings 31 on the array substrate 1. The orthographic projection of the pixel opening 31 on the array substrate 1 is located within the orthographic projection of the isolation opening 6 on the array substrate 1.

[0177] When forming the light-emitting functional layer, the light-emitting functional layer is partitioned by the isolation structure 7 to form a plurality of spaced light-emitting portions 4. When forming the second electrode layer, the second electrode layer is partitioned by the isolation structure 7 to form a plurality of spaced second electrodes 5. The isolation structure 7 includes a conductive material, and the second electrodes 5 are electrically connected to the isolation structure 7. One first electrode 2, one light-emitting portion 4, and one second electrode 5 form a light-emitting device 8. The first electrode 2 is an anode, and the second electrode 5 is a cathode.

[0178] For some possible implementations, see again Figure 4The isolation structure 7 includes a first isolation portion 71 and a second isolation portion 72 which are sequentially stacked in a direction away from the array substrate 1. A normal projection of a side of the first isolation portion 71 away from the array substrate 1 on the array substrate 1 is located within a normal projection of the second isolation portion 72 on the array substrate 1.

[0179] Since the second isolation portion 72 is located on a side of the first isolation portion 71 away from the array substrate 1, and a lateral width of the second isolation portion 72 is greater than a lateral width of the first isolation portion 71, the second isolation portion 72 can disconnect the light-emitting functional layer and the second electrode layer at the isolation structure 7. In this way, the isolation structure 7 formed by the first isolation portion 71 and the second isolation portion 72 can more easily independently encapsulate each light-emitting device 8.

[0180] In some possible implementation manners, referring again to Figure 4 The second electrode 5 of the light-emitting device 8 is electrically connected to the first isolation portion 71. The first isolation portion 71 includes a conductive material, and the corresponding second electrode 5 of the light-emitting device 8 extends to contact a side wall of the first isolation portion 71, so as to electrically connect the corresponding second electrode 5 of the light-emitting device 8 to the first isolation portion 71.

[0181] Referring again to Figure 10 The isolation structure 7 further includes a third isolation portion 73 located on a side of the first isolation portion 71 facing the array substrate 1. The second electrode 5 of the light-emitting device 8 is electrically connected to the third isolation portion 73.

[0182] The third isolation portion 73 includes a conductive material, and the corresponding second electrode 5 of the light-emitting device 8 extends to contact a side wall of the third isolation portion 73, so as to electrically connect the corresponding second electrode 5 of the light-emitting device 8 to the third isolation portion 73.

[0183] Specifically, the third isolation portion 73 includes molybdenum metal; and / or, the first isolation portion 71 includes aluminum metal; and / or, the second isolation portion 72 includes titanium metal. In this way, when the isolation structure 7 disconnects the second electrode layer into the second electrode 5, the second electrode 5 is more easily electrically connected to the first isolation portion 71 and / or the third isolation portion 73.

[0184] In some possible implementation manners, the present application further provides another display panel. The display panel includes an array substrate 1, an isolation structure 7, a light-emitting device 8, and a first encapsulation layer 9.

[0185] The isolation structure 7 is located on a side of the array substrate 1. The isolation structure 7 encloses to form an isolation opening 6.

[0186] The light-emitting device 8 is located in the isolation opening 6. The light-emitting device 8 includes a plurality of light-emitting sub-devices. For example, the light-emitting device 8 includes a first light-emitting sub-device and a second light-emitting sub-device.

[0187] The first encapsulation layer 9 is located on a side of the light emitting device 8 away from the array substrate 1, and the first encapsulation layer 9 includes a plurality of encapsulation units 91 arranged at intervals, at least part of the encapsulation units 91 extending from a side of the isolation structure 7 to a side of the isolation structure 7 away from the array substrate 1, the side of the isolation structure 7 being a side of the isolation structure 7 facing the isolation opening 6.

[0188] The encapsulation unit 91 includes a wrapping part 911 located on a side of the isolation structure 7 away from the array substrate 1, and the wrapping parts 911 located on different sides of the same light emitting sub-device have equal lengths extending away from the isolation opening 6.

[0189] For example, Figure 3 The wrapping part 911 along the direction b of the same light emitting sub-device has a length D4 extending away from the isolation opening 6, and the wrapping part 911 along the direction a has a length D3 extending away from the isolation opening 6, wherein the direction a can be a direction in which a scan line of the display panel extends in the display area, the angle between the direction b and the direction a is β, and β is greater than 0° and less than 360°, for example, β can be 60°, 90° or 120°, etc.

[0190] In this way, the light emitted by the same light emitting sub-device in different directions can be made more the same, thereby improving the display uniformity of the display panel, and further improving the display effect of the display panel.

[0191] In some possible implementation manners, referring back to Figure 2 The application further provides another display panel, which includes an array substrate 1, an isolation structure 7, a light emitting device 8 and a first encapsulation layer 9.

[0192] The isolation structure 7 is located on a side of the array substrate 1, and the isolation structure 7 encloses to form an isolation opening 6.

[0193] The light emitting device 8 is located in the isolation opening 6, and the light emitting device 8 includes a plurality of light emitting sub-devices.

[0194] The first encapsulation layer 9 is located on a side of the light emitting device 8 away from the array substrate 1, and the first encapsulation layer 9 includes a plurality of encapsulation units 91 arranged at intervals, at least part of the encapsulation units 91 including a first encapsulation part 910 located in the isolation opening 6 and a second encapsulation part 911 located on a side of the isolation structure 7 away from the array substrate 1;

[0195] The second encapsulation part 911 located on different sides of the same light emitting sub-device has equal lengths extending away from the isolation opening.

[0196] In some possible implementation manners, referring back to Figure 2The application further provides another display panel, which comprises an array substrate 1, an isolation structure 7, a light emitting device 8 and a first encapsulation layer 9.

[0197] The isolation structure 7 is located on one side of the array substrate 1, and the isolation structure 7 encloses the isolation opening 6.

[0198] The light emitting device 8 is located in the isolation opening 6, and the light emitting device 8 comprises a plurality of light emitting sub-devices, for example, the light emitting device 8 comprises a first light emitting sub-device and a second light emitting sub-device.

[0199] The first encapsulation layer 9 is located on the side of the light emitting device 8 away from the array substrate 1, and the first encapsulation layer 9 comprises a plurality of encapsulation units 91 arranged at intervals, at least part of the encapsulation units 91 comprises a first encapsulation part 910 located in the isolation opening 6 and a second encapsulation part 911 located on the side of the isolation structure 7 away from the array substrate 1.

[0200] The second encapsulation part 910 of the encapsulation unit 91 corresponding to the encapsulation of the first light emitting sub-device comprises a first edge wrapping part 9111, which has a first extension length D1 in the cross section perpendicular to the extension direction of the isolation structure 7 enclosing the first light emitting sub-device, and the second encapsulation part 910 of the encapsulation unit 91 corresponding to the encapsulation of the second light emitting sub-device comprises a second edge wrapping part 9112, which has a second extension length D2 in the cross section perpendicular to the extension direction of the isolation structure 7 enclosing the second light emitting sub-device, and the first extension length D1 is equal to the second extension length D2.

[0201] According to the manufacturing sequence of the first light emitting sub-device and the second light emitting sub-device, the embodiment ensures that after the first light emitting sub-device and the second light emitting sub-device are manufactured, the length D1 of the first edge wrapping part 9111 located on the periphery of the first light emitting sub-device and the length D2 of the second edge wrapping part 9112 located on the periphery of the second light emitting sub-device are equal along the preset direction, that is, the distance between the orthographic projection of the edge wrapping part 911 corresponding to the first light emitting sub-device and the second light emitting sub-device on the side of the array substrate 1 facing the isolation opening 6 and the orthographic projection on the side away from the isolation opening 6 is equal.

[0202] Here, the length D1 can not be absolutely equal to the length D2, as long as the difference between the length D1 and the length D2 is within a preset error range. For example, the length D1 can be considered equal to the length D2 when the length D1 is 5%-20% longer than the length D2. In addition, the isolation opening 6 in the phrase "the edge covering part 911 extends in a direction away from the isolation opening 6" refers to the isolation opening 6 corresponding to the edge covering part 911. In this way, the packaging unit 91 has substantially the same effect on the light emission of the first light emitting sub-device and the second light emitting sub-device, thereby making the light emission of the first light emitting sub-device and the second light emitting sub-device more consistent. In addition, the length of the edge covering part 911 effectively ensures the packaging effect of the light emitting sub-device, avoids packaging cracks caused by subsequent processes, and finally improves the display effect of the display panel.

[0203] In some possible implementation manners, referring again to Figure 5 and Figure 6 , the application further provides another display panel, which comprises an array substrate 1, an isolation structure 7, a light emitting device 8, and a first packaging layer 9.

[0204] The isolation structure 7 is located on one side of the array substrate 1, and the isolation structure 7 encloses to form an isolation opening 6.

[0205] The light emitting device 8 is located in the isolation opening 6, and the light emitting device 8 comprises a plurality of light emitting sub-devices, for example, the light emitting device 8 comprises a first light emitting sub-device and a second light emitting sub-device.

[0206] The first packaging layer 9 is located on a side of the light emitting device 8 away from the array substrate 1, and the first packaging layer 9 comprises a packaging unit 91. At least part of the packaging unit 91 extends from the side of the isolation structure 7 to the side of the isolation structure 7 away from the array substrate 1.

[0207] In the application, the orthographic projection of adjacent packaging units 91 on the array substrate 1 at least partially overlaps. The second packaging part 910 of the packaging unit 91 corresponding to the first light emitting sub-device comprises a first edge covering part 9111, which has a first extension length D1 in a cross section perpendicular to the extension direction of the isolation structure 7 enclosing the first light emitting sub-device. The second packaging part 910 of the packaging unit 91 corresponding to the second light emitting sub-device comprises a second edge covering part 9112, which has a second extension length D2 in a cross section perpendicular to the extension direction of the isolation structure 7 enclosing the second light emitting sub-device. The first extension length D1 is equal to the second extension length D2.

[0208] By setting the second extension part 91102 of the first light emitting sub-device and the second extension part 91102 of the second light emitting sub-device to be at least partially coincident, the packaging effect of the first light emitting sub-device and the second light emitting sub-device can be improved, and the second extension part 91102 away from the array substrate 1 side can also protect the second extension part 91102 close to the array substrate 1 side, so that the second extension part 91102 close to the array substrate 1 side is not easy to break.

[0209] By setting the length of the first edge cover part 9111 on at least one side of the first light emitting sub-device to be equal to the length of the second edge cover part 9112 on at least one side of the second light emitting sub-device, the display effect of the display panel can be improved.

The electronic device can include a device with image processing capability, for example, a server, a personal computer, a notebook computer, etc. Since the electronic device includes the display panel in the present application, the display effect of the electronic device is better.
