DETAILED DESCRIPTION

[0051] The features and exemplary embodiments of various aspects of the application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented when some details in these specific details are not needed. The following description of the embodiments is only to provide a better understanding of the application by illustrating the example of the application.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0053] The inventor has found through research that the light transmittance of the under-screen camera area in the display panel is low, which makes it difficult to meet the camera module's demand for light, causing the performance of the camera module in the display device to be difficult to meet the needs of users. Based on the research on the above problem, the inventor provides a display panel and a display device to improve the light transmittance of the display panel, thereby improving the performance of the camera module.

[0054] In order to better understand this application, Figures 1 to 25 The display panel and the display device according to the embodiments of the present application are described in detail.

[0055] See also Figure 1 , an embodiment of the present application provides a display panel 1, including a first display area A1.

[0056] like Figure 2 and Figure 3As shown, the display panel 1 provided in the present application includes a substrate 10, a light-emitting unit 11 and an isolation structure 12. There are multiple light-emitting units 11, each of which includes a first electrode 111, a light-emitting functional unit 112 and a second electrode 113 stacked in a direction away from the substrate 10, and the second electrodes 113 of adjacent light-emitting units 11 are arranged at intervals. The multiple light-emitting units 11 include at least one first light-emitting unit 114 located in the first display area A1. The isolation structure 12 is formed on one side of the substrate 10, and the isolation structure 12 includes multiple first isolation structures 120 arranged at intervals in the first display area A1, and the first isolation structure 120 includes a first entity portion 121 and a first opening portion 122, and the first entity portion 121 is arranged around the first opening portion 122, and the first opening portion 122 exposes at least part of the first electrode 111 of the first light-emitting unit 114, and the second electrode 113 of the first light-emitting unit 114 is electrically connected to the first isolation structure 120, and at least part of the adjacent first isolation structures 120 are electrically connected through the light-transmitting connection portion 13.

[0057] The display panel 1 provided in the present application includes a substrate 10, a light-emitting unit 11 and an isolation structure 12. The light-emitting unit 11 includes a first light-emitting unit 114 located in the first display area A1, and the isolation structure 12 includes a first isolation structure 120 located in the first display area A1. The first isolation structure 120 includes a first solid portion 121 and a first opening portion 122, the first solid portion 121 is arranged around the first opening portion, and the first opening portion 122 exposes at least part of the first electrode 111 of the first light-emitting unit 114. Adjacent first isolation structures 120 are arranged at intervals, and the second electrodes 113 of adjacent first light-emitting units 114 are arranged at intervals, and the second electrodes 113 of the first light-emitting units 114 are electrically connected to the first isolation structure 120. At least part of the adjacent first isolation structures 120 are electrically connected through the light-transmitting connection portion 13. On the one hand, the electrical connection of at least part of the second electrodes 113 in the first display area A1 can be realized, so as to reduce the number and length of power supply lines for supplying power to the second electrodes 113 in the first display area A1, which helps to simplify wiring. On the other hand, adjacent first isolation structures 120 are spaced apart so that a spacing area is formed between adjacent first isolation structures 120, and a light-transmitting connecting portion 13 is provided in the spacing area. The light-transmitting connecting portion 13 has a strong light-transmitting performance, thereby improving the light transmittance of the area between adjacent first isolation structures 120, so as to improve the light transmittance of the first display area A1, and provide a basis for integrating a photosensitive device or realizing a transparent display under the first display area A1.

[0058] Specifically, the first isolation structure 120 may correspond to the first light emitting unit 114 one by one, which is not particularly limited in the present application.

[0059] In a feasible implementation, the material of the light-transmitting connecting portion 13 may include transparent conductive materials such as indium tin oxide and / or indium zinc oxide, which is not particularly limited in the present application.

[0060] In a possible implementation, Figure 2 As shown, the light-transmitting connecting portion 13 is a mesh structure that is continuously arranged in an entire layer, and includes a via hole 131 that is opposite to the first opening portion 122 .

[0061] In the above embodiment, the light-transmitting connecting portion 13 is continuously arranged in an entire layer, and a via 131 arranged opposite to the first opening portion 122 is formed by patterning, thereby exposing the first light-emitting unit 114. The light-transmitting connecting portion 13 is in a mesh design arranged in an entire layer, so that its own area can be larger, thereby reducing its resistance, thereby reducing the power consumption of the display panel 1. At the same time, since it covers the area between the adjacent first isolation structures 120, the effect of the patterning of the light-transmitting connecting portion 13 itself on the optical performance of the photosensitive device integrated under the first display area A1 can be reduced, and the probability of diffraction of light when passing through the light-transmitting connecting portion 13 can be reduced, thereby reducing the adverse effects of diffraction on the photosensitive device.

[0062] In addition, the light-transmitting connecting portion 13 is a continuously arranged mesh structure that can effectively shield the signal interference between the film layer on the side of the first isolation structure 120 away from the substrate 10 and the substrate 10. Specifically, the display panel 1 may also include a touch layer, which is located on the side of the isolation structure away from the substrate 10, and the light-transmitting connecting portion 13 is located between the substrate 10 and the touch layer. The touch layer includes touch electrodes, and the substrate 10 is provided with signal lines for driving the first light-emitting unit to display, such as data signal lines. The touch electrodes and the signal lines in the substrate 10 may interfere with each other. By arranging the light-transmitting connecting portion 13 of the mesh structure between the touch layer and the substrate 10, the interference between the touch electrodes and the signal lines in the substrate 10 can be reduced by the shielding effect of the light-transmitting connecting portion 13 of the mesh structure, thereby improving the performance of the display panel 1.

[0063] In the above embodiment, the orthographic projection of the via hole 131 on the substrate 10 may be set to be larger than the orthographic projection of the first opening 122 on the substrate 10 , so as to avoid the first light emitting unit 114 .

[0064] In a possible implementation, Figure 4 As shown, the light-transmitting connecting portion 13 is strip-shaped and is disposed between two adjacent first isolation structures 120 . One end of the light-transmitting connecting portion 13 is electrically connected to one first isolation structure 120 , and the other end is electrically connected to the other first isolation structure 120 .

[0065] In the above embodiment, the light-transmitting connecting portion 13 is in a strip shape, which can further reduce the influence of the light-transmitting connecting portion 13 on the light transmittance of the area between the first isolation structures 120 , thereby further improving the light transmittance of the first display area A1 .

[0066] In a possible implementation, Figure 4 As shown, the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10 extends along a straight line, or as Figure 5 As shown, the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10 extends along the curved direction.

[0067] In the above embodiment, the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10 extends in a straight line direction, so that the total length of the light-transmitting connecting portion 13 can be shorter, thereby further reducing the influence on the light transmittance of the area between the first isolation structures 120. At the same time, extending in a straight line direction can reduce the difficulty of preparing the light-transmitting connecting portion 13 and reduce the preparation cost.

[0068] In the above embodiment, the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10 extends along the curved direction, thereby reducing the probability that the shape of the light-transmitting connecting portion 13 causes diffraction of light, thereby reducing the influence of the patterning of the light-transmitting connecting portion 13 itself on the optical performance of the photosensitive device integrated under the first display area A1.

[0069] In a possible implementation, Figure 3 As shown, the first isolation structure 120 includes a first isolation portion 123, the first isolation portion 123 includes a first insulating layer 1231 and a second conductive layer 1232, the first insulating layer 1231 at least covers the edge of the first electrode 111 of the first light-emitting unit 114, the second conductive layer 1232 is located on the side of the first insulating layer 1231 away from the substrate 10, and the second electrode 113 and the light-transmitting connecting portion 13 of the first light-emitting unit 114 are electrically connected to the second conductive layer 1232, respectively.

[0070] In the above embodiment, the pixel definition layer 14 in the display panel 1 is omitted, and the isolation structure 12 is used to define the light-emitting unit 11. The isolation structure 12 includes a first isolation structure 120, and the first isolation structure 120 includes a first isolation portion 123. The first isolation portion 123 includes a first insulating layer 1231 and a first conductive layer 1232. The first conductive layer 1232 is located on the side of the first insulating layer 1231 away from the substrate 10. The first insulating layer 1231 is in direct contact with the substrate 10 and the side of the first electrode 111 of the first light-emitting unit 114 away from the substrate 10. The first insulating layer 1231 covers the edge of the first electrode 111 of the first light-emitting unit 114 to achieve mutual insulation between the first electrodes 111 of adjacent first light-emitting units 114 and protect the first electrodes 111 of the first light-emitting units 114. The first conductive layer 1232 and the light-transmitting connecting portion 13 are used to realize the interconnection of the second electrodes 113 of different first light-emitting units 114. Specifically, the second electrode 113 of the first light-emitting unit 114 is in direct contact with the side wall of the first conductive layer 1232 to realize the electrical connection between the second electrode 113 of the first light-emitting unit 114 and the first isolation structure 120. Adjacent first isolation structures 120 are electrically connected via the light-transmitting connecting portion 13, thereby realizing the electrical connection between the second electrodes 113 of different first light-emitting units 114.

[0071] In a possible implementation, Figure 3 As shown, the first isolation structure 120 further includes a second isolation portion 124 , which is located on a side of the first isolation portion 123 away from the substrate 10 , and the orthographic projection of the first isolation portion 123 on the substrate 10 is located within the orthographic projection of the second isolation portion 124 on the substrate 10 .

[0072] In the above embodiment, the first isolation structure 120 includes a first isolation portion 123 and a second isolation portion 124 stacked in a direction away from the substrate, and the orthographic projection of the first isolation portion 123 on the substrate 10 is located within the orthographic projection of the second isolation portion 124 on the substrate 10. Therefore, when preparing the first light-emitting units 114 of various colors, the various film layers in the first light-emitting units 114 of one color can be formed on the entire surface, and then the first light-emitting units 114 of the color are formed at the designated first openings 122 by etching, and the first openings 122 for forming the first light-emitting units 114 of other colors are exposed. The first light-emitting units 114 of different colors are prepared in multiple times, and the above preparation process does not require the use of a mask plate, and at the same time, it is not necessary to prepare the pixel definition layer 14 and the support column located on the side of the pixel definition layer 14 away from the substrate 10 for supporting the mask plate, thereby saving the preparation cost. The first isolation structure 120 can be prepared and formed with a dark material, so that it can have a light-shielding effect and prevent the cross-light between adjacent first light-emitting units 114.

[0073] In a feasible implementation, the first isolation structure 120 is an annular structure disposed around at least one first light emitting unit 114. This can define the first light emitting unit 114, achieve the spacing between adjacent first isolation structures 120, and improve the light transmittance between adjacent first isolation structures 120.

[0074] In a possible implementation, Figure 6 As shown, the display panel 1 further includes a pixel definition layer 14, which is located between the first electrode 111 and the isolation structure 12, and includes a pixel defining portion 141 and a pixel opening 142, and the pixel opening 142 corresponds to the first opening portion 122 one by one and is interconnected to accommodate the light-emitting unit 11. The first isolation structure 120 includes a third isolation portion 125, and the third isolation portion 125 includes a conductive material, and the light-transmitting connecting portion 13 and the second electrode of the first light-emitting unit are respectively connected to the third isolation portion 125.

[0075] In the above embodiment, the display panel 1 includes a pixel definition layer 14 and an isolation structure 12 located on a side of the pixel definition layer 14 away from the substrate 10. The pixel definition layer 14 is used to define the light-emitting unit 11. The first isolation structure 120 includes a third isolation portion 125 directly in contact with a surface of the side of the pixel definition layer 14 away from the substrate 10, the third isolation portion 125 includes a conductive material, and the second electrode 113 and the light-transmitting connecting portion 13 of the first light-emitting unit 114 are respectively connected to the third isolation portion 125, so that the electrical connection of the second electrodes 113 of different first light-emitting units 114 can be achieved.

[0076] In a possible implementation, Figure 6 As shown, the third isolation portion 125 includes a first layer 1251 and a second layer 1252. The second layer 1252 is located on the side of the first layer 1251 away from the substrate 10. The first layer 1251 includes a conductive material. The transparent connecting portion 13 and the second electrode of the first light-emitting unit 114 are respectively connected to the first layer 1251.

[0077] In the above embodiment, the material of the first layer 1251 can be metal, such as molybdenum, and the material of the second layer 1252 can be metal, such as aluminum. The first layer 1251 can protect the second layer 1252 and prevent the second layer 1252 from being oxidized by water and oxygen on the substrate 10 side.

[0078] In the above embodiment, the first isolation structure 120 may further include a fourth isolation portion 126 , and the orthographic projection of the third isolation portion 125 on the substrate 10 is located within the orthographic projection of the fourth isolation portion 126 on the substrate 10 .

[0079] In the above embodiment, the first isolation structure 120 includes a third isolation portion 125 and a fourth isolation portion 126, and the orthographic projection of the third isolation portion 125 on the substrate 10 is located within the orthographic projection of the fourth isolation portion 126 on the substrate 10, so that when preparing the first light-emitting units 114 of various colors, the various film layers in the first light-emitting units 114 of one color can be formed on the entire surface, and then the first light-emitting units 114 of the color are formed at the designated first openings 122 by etching, and the first openings 122 for forming the first light-emitting units 114 of other colors are exposed. The first light-emitting units 114 of different colors are prepared in multiple times, and the above preparation process does not require the use of a mask plate, and at the same time, it is not necessary to prepare the pixel definition layer 14 and the support column located on the side of the pixel definition layer 14 away from the substrate 10 for supporting the mask plate, thereby saving the preparation cost. The first isolation structure 120 can be prepared and formed with a dark material, so that it can have a light-shielding effect and prevent the cross-light between adjacent first light-emitting units 114.

[0080] In a possible implementation, Figure 6 As shown, the light-transmitting connecting portion 13 and the first layer 1251 are arranged in a direction parallel to the plane where the substrate 10 is located and contact each other. The orthographic projection of the second layer 1252 on the substrate 10 covers a part of the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10, or the orthographic projection of the second layer 1252 on the substrate 10 does not overlap with the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10.

[0081] In the above embodiment, the light-transmitting connecting portion 13 and the side wall of the first layer 1251 are in contact with each other, thereby realizing electrical connection between the light-transmitting connecting portion 13 and the first layer 1251. And a part of the light-transmitting connecting portion 13 is located between the second layer 1252 and the pixel definition layer 14, that is, the orthographic projection of the second layer 1252 on the substrate 10 covers a part of the orthographic projection of the light-transmitting connecting portion 13 on the substrate 10, so that the contact part between the first layer 1251 and the light-transmitting connecting portion 13 can be protected by the second layer 1252, reducing the impact of subsequent process steps on the above contact part. At the same time, when the material of the second layer 1252 is metal, the contact resistance between the light-transmitting connecting portion 13 and the first layer 1251 can be further reduced.

[0082] In a possible implementation, Figure 7 As shown, a part of the transparent connecting portion 13 is located on the side of the first layer 1251 away from the substrate 10 and covers the edge of the first layer 1251, and the orthographic projection of the second layer 1252 on the substrate 10 covers a part of the orthographic projection of the transparent connecting portion 13 on the substrate 10. Thus, the electrical connection between the transparent connecting portion 13 and the first layer 1251 can be achieved. The contact part between the first layer 1251 and the transparent connecting portion 13 can be protected by the second layer 1252. In another feasible embodiment, as Figure 8 As shown, the light-transmitting connecting portion 13 contacts the side of the pixel definition layer 14 facing away from the substrate 10 , and the first layer 1251 covers the edge of the light-transmitting connecting portion 13 .

[0083] In the above embodiment, the light-transmitting connection portion 13 is formed on the side of the pixel definition layer 14 facing away from the substrate 10, and the first layer 1251 is formed on the side of the light-transmitting connection portion 13 facing away from the substrate 10, that is, the light-transmitting connection portion 13 is prepared first, and then the first layer 1251 is prepared. The first layer 1251 covers the edge of the light-transmitting connection portion 13, that is, the first layer 1251 contacts the side wall of the light-transmitting connection portion 13 facing the first opening portion 122, and at the same time, the first layer 1251 contacts the surface of the light-transmitting connection portion 13 facing away from the substrate 10, which can increase the contact area between the first layer 1251 and the light-transmitting connection portion 13, so as to improve the connection stability between the two, and reduce the contact resistance between the two.

[0084] In another possible implementation, if Fig. 9 As shown, the light-transmitting connecting portion 13 and the first layer 1251 are made of the same material, and the light-transmitting connecting portion 13 and the first layer 1251 are an integrated structure.

[0085] In the above embodiment, the light-transmitting connecting portion 13 and the first layer 1251 are formed by one process and have an integrated structure. In this case, the connection stability between the two is stronger, and the preparation process can be saved and the preparation cost can be reduced. In this case, the material of the first layer 1251 is the same as that of the light-transmitting connecting portion 13, and both are transparent conductive materials.

[0086] In the above embodiment, if Fig.10 As shown, one end of the first layer 1251 close to the first opening portion 122 has a first extension portion 1253 extending out from the second layer 1252, and the orthographic projection of the first extension portion 1253 on the substrate 10 does not overlap with the orthographic projection of the second layer 1252 on the substrate 10, and the orthographic projection of the first extension portion 1253 on the substrate 10 is located within the orthographic projection of the fourth isolation portion 126 on the substrate 10.

[0087] In the above embodiment, by setting the first extension portion 1253 on the first layer 1251, a preset distance is made between one end of the second layer 1252 close to the first opening portion 122 and one end of the first layer 1251 close to the first opening portion 122, which can further increase the contact area between the second electrode 113 of the first light-emitting unit 114 and the first layer 1251, and improve the stability of the electrical connection between the second electrode 113 of the first light-emitting unit 114 and the first isolation structure 120. At the same time, the contact resistance can be reduced.

[0088] In a possible implementation, Fig.11 and Figure 2As shown, the display panel 1 further includes a second display area A2, that is, the display panel includes a first display area A1 and a second display area A2, and the second display area A2 surrounds at least a portion of the first display area A1.

[0089] The display panel 1 provided in the present application includes a first display area A1 and a second display area A2, and the light transmittance of the second display area A2 can be set to be less than the light transmittance of the first display area A1, so as to facilitate the integration of a photosensitive device, such as a camera module, under the first display area A1. Alternatively, the light transmittance of the first display area A1 and the light transmittance of the second display area A2 can be the same, so as to achieve transparent display. This application does not specifically limit this.

[0090] In the display panel provided in the present application, the light-emitting unit 11 also includes a second light-emitting unit 115 located in the second display area A2, the orthographic projection of the first light-emitting unit 114 on the substrate 10 is smaller than the orthographic projection of the second light-emitting unit 115 of the same color on the substrate 10, and the spacing between adjacent first light-emitting units 114 is greater than the spacing between adjacent second light-emitting units 115.

[0091] Specifically, the display panel 1 may include at least three colors of light-emitting units 11. Among them, at least three colors of first light-emitting units 114 may be included, specifically including a red first light-emitting unit 1141, a green first light-emitting unit 1142, and a blue first light-emitting unit 1143. At the same time, at least three colors of second light-emitting units 115 may be included, specifically including a red second light-emitting unit 1151, a green second light-emitting unit 1152, and a blue second light-emitting unit 1153.

[0092] Specifically, the arrangement of the first light-emitting units 114 in the first display area A1 may be the same as or different from the arrangement of the second light-emitting units 115 in the second display area A2, which is not particularly limited in the present application.

[0093] Specifically, the orthographic projection of the first light-emitting unit 114 on the substrate 10 is smaller than the orthographic projection of the second light-emitting unit 115 of the same color on the substrate 10, thereby improving the transmittance in the first display area A1, so as to achieve better effects when integrating a photosensitive device under the first display area A1 or realizing transparent display.

[0094] Specifically, the spacing between adjacent first light-emitting units 114 is greater than the spacing between adjacent second light-emitting units 115. The spacing between any two adjacent first light-emitting units 114 may be greater than the spacing between any two adjacent second light-emitting units 115, or the spacing between any two adjacent first light-emitting units 114 of the first color may be greater than the spacing between any two adjacent second light-emitting units 115 of the first color, wherein the first color may be red, green, or blue, which is not particularly limited in this application. The above-mentioned arrangement can reduce the ratio of the total area of ​​all first light-emitting units 114 in the first display area A1 to the total area of ​​the first display area A1, and further improve the light transmittance of the first display area A1.

[0095] In a possible implementation, Fig.11 and Fig.12 As shown, the isolation structure 12 also includes a second isolation structure 15 located in the second display area A2. The second isolation structure 15 is located on the side of the first electrode 111 of the second light-emitting unit 115 away from the substrate 10. The second isolation structure 15 has a mesh structure, including a second solid portion 151 and a second opening portion 152. The second solid portion 151 is continuously arranged in an entire layer, and the second opening portion 152 is used to expose at least a portion of the first electrode 111 of the second light-emitting unit 115.

[0096] In the above embodiment, the second isolation structure 15 is prepared in the same layer as the first isolation structure 120, that is, the whole layer is prepared during the preparation process, and then the first display area A1 and the second display area A2 are patterned respectively to form the first isolation structure 120 in the first display area A1 and the second isolation structure 15 in the second display area A2. The second isolation structure 15 has the same function as the first isolation structure 120, and both can omit the mask plate during the preparation process of the light-emitting unit 11, improve the preparation process of the light-emitting unit 11, and reduce the crosstalk problem between adjacent light-emitting units 11.

[0097] Specifically, the number and material of the film layers of the second isolation structure 15 and the first isolation structure 120 are the same, and will not be described in detail in this application.

[0098] In the above embodiment, in the second display area A2, the second electrode 113 of the second light-emitting unit 115 is electrically connected to the second entity portion 151, so that the second electrodes 113 of the spaced second light-emitting units 115 can be electrically connected through the second entity portion 151 to save the number of power supply lines and simplify wiring.

[0099] In a possible implementation, Fig.13 As shown, the second isolation structure 15 further includes a light-transmitting hole 153 , and the light-transmitting hole 153 is located between adjacent second opening portions 152 .

[0100] The light-transmitting holes 153 may be provided on the second isolation structure 15 in a partial area of ​​the second display area A2, or may be provided on the second isolation structure 15 in the entire area of ​​the second display area A2. The density of the light-transmitting holes 153 in each area of ​​the second display area A2 may be the same or different, and may be set according to requirements.

[0101] In the above embodiment, the light transmittance of the second display area A2 can be improved by setting a light-transmitting hole 153 in the second isolation structure 15 adjacent to the second opening portion 152 , while keeping the entire layer of the second entity portion 151 in the second isolation structure 15 continuously set to achieve electrical connection between different second electrodes 113 .

[0102] In a feasible embodiment, the second display area A2 includes a first display sub-area A21 and a second display sub-area A22, the transmittance of the first display area A1 is greater than the transmittance of the first display sub-area A21, the transmittance of the first display sub-area A21 is greater than the transmittance of the second display sub-area A22, and the light-transmitting hole 152 is arranged on the second isolation structure 15 in the first display sub-area A21.

[0103] In the above embodiment, when at least one of a fingerprint identification module (FOD), a light sensor, and a distance measurement sensor is integrated under the display panel 1, a light-transmitting hole 153 is formed in the area between adjacent second light-emitting units 115 in the second isolation structure 15 for light transmission, thereby realizing fingerprint identification, detecting the intensity of ambient light, and distance measurement. Among them, the first display sub-area A21 is an area for setting the light-transmitting hole 152, and the first display sub-area A21 is located between adjacent second light-emitting units 115.

[0104] In the above embodiment, the orthographic projection of the light-transmitting hole 153 on the substrate 10 can be any one of a quadrilateral, a circle, and an ellipse, which is not particularly limited in the present application.

[0105] In a possible implementation, Fig.13 As shown, it also includes a first shielding portion 16, which is arranged on one side of the substrate 10. The orthographic projection of the first shielding portion 16 on the substrate 10 covers the orthographic projection of the light-transmitting hole 153 on the substrate 10, and the first shielding portion 16 is a light-transmitting structure.

[0106] In the above embodiment, the first shielding portion 16 corresponds to the light-transmitting hole 153 one by one, and the orthographic projection of the first shielding portion 16 on the substrate 10 covers the orthographic projection of the light-transmitting hole 153 on the substrate 10. Specifically, the first shielding portion 16 can be formed between the second isolation structure 15 and the substrate 10, and the first shielding portion 16 is in contact with the second isolation structure 15. The first shielding portion 16 can effectively shield the signal interference between the film layer on the side of the second isolation structure away from the substrate 10 and the substrate 10. Specifically, the display panel 1 may include a touch layer, which is located on the side of the second isolation structure 15 away from the substrate 10. The touch layer includes touch electrodes. The substrate 10 is provided with a signal routing for driving the light-emitting unit 11 to display. By providing the first shielding portion 16 at the light-transmitting hole 153, the mutual interference between the touch electrode and the signal routing in the substrate 10 at the light-transmitting hole 153 can be reduced, thereby improving the performance of the display panel 1. Specifically, the second isolation structure 15 includes a metal layer, which can shield the position outside the light-transmitting hole 153 to reduce the mutual interference between the touch signal and the display signal.

[0107] Specifically, the first shielding portion 16 is electrically connected to the isolation structure 12 .

[0108] Specifically, the number of the first shielding parts 16 and the number of the light-transmitting holes 153 are both plural, and the plurality of first shielding parts 16 and the plurality of light-transmitting holes 153 are arranged in a one-to-one correspondence.

[0109] In a feasible implementation, the first shielding portion 16 and the light-transmitting connecting portion 13 are disposed in the same layer. That is, the first shielding portion 16 and the light-transmitting connecting portion 13 are both made of transparent conductive material, and can be patterned in the first display area A1 and the second display area A2 after the whole layer is prepared to form the first shielding portion 16 and the light-transmitting connecting portion 13. The preparation of the two in the same layer can simplify the preparation process.

[0110] In a possible implementation, Fig.14 As shown, the second electrode 113 of the first light-emitting unit 114 is electrically connected to the second electrode 113 of the second light-emitting unit 115 through the light-transmitting connecting portion 13 .

[0111] That is, in the above embodiment, each second electrode 113 in the first display area A1 can be electrically connected through the first isolation structure 120 and the light-transmitting connecting portion 13, and each second electrode 113 in the second display area A2 can be electrically connected through the second isolation structure 15. By electrically connecting the light-transmitting connecting portion 13 with the second isolation structure 15, the electrical connection of the second electrodes 113 in the entire display panel 1 (including the first display area A1 and the second display area A2) is achieved, so that the second electrodes 113 in the entire display panel 1 can be centrally powered, thereby simplifying the wiring.

[0112] Specifically, at the position adjacent to the first display area A1 and the second display area A2 , the first entity portion 121 of the first isolation structure 120 is electrically connected to the second entity portion 151 of the second isolation structure 15 through the transparent connecting portion 13 , thereby achieving electrical connection of the second electrode 113 in the display panel 1 .

[0113] In a feasible embodiment, the substrate 10 includes a first driving circuit located in the first display area A1, and the first electrode 111 of the first light-emitting unit 114 is connected to the first driving circuit through the first electrode wiring 17; the first electrode wiring 17 includes a transparent conductive material. The first electrode wiring 17 uses a transparent conductive material, so that the light transmittance of the first display area A1 can be improved.

[0114] In a feasible embodiment, the display panel 1 also includes a transition zone A3, which is located between the first display zone A1 and the second display zone A2. The light-emitting unit 11 includes a third light-emitting unit 116 located in the transition zone A3. The substrate 10 includes a second driving circuit located in the transition zone A3. The first electrode 111 of the third light-emitting unit 116 is connected to the second driving circuit through the second electrode wiring 19, and the first electrode 111 of the first light-emitting unit 114 is connected to the second driving circuit through the second electrode wiring 19.

[0115] In the above embodiment, by setting the transition area A3 and electrically connecting the third light-emitting unit 116 located in the transition area A3 and the first light-emitting unit 114 located in the first display area A1 to the second driving circuit located in the transition area A3, the preparation of the first driving circuit in the first display area A1 can be omitted, thereby further improving the transmittance of the first display area A1.

[0116] Specifically, the second electrode traces 19 include a transparent conductive material to further improve the light transmittance of the first display area A1 and the transition area A3.

[0117] In a feasible implementation manner, the isolation structure 12 further includes a third isolation structure 21 located in the transition area A3 , and the second electrode 113 of the third light emitting unit 116 is connected to the third isolation structure 21 .

[0118] Specifically, the third isolation structure 21 is continuously arranged with the second isolation structure 15, and the third isolation structure 21 is electrically connected with the first isolation structure 120 through the light-transmitting connection part 13; or, the third isolation structure 21 has the same structure as the first isolation structure 120, and the third isolation structure 21 is electrically connected with the second isolation structure 15 through the light-transmitting connection part 13.

[0119] The third isolation structure 21 is arranged in the transition area A3, so that when the third light-emitting unit 116 is prepared, each film layer in the third light-emitting unit 116 of one color can be formed on the whole surface first, and then the third light-emitting unit 116 of this color is formed at the specified position by etching, and the position for forming the third light-emitting unit 116 of other colors is exposed. The third light-emitting units 116 of different colors are prepared in multiple times, and no mask plate is required in the above preparation process, and no pixel definition layer 14 and a support column located on the side of the pixel definition layer 14 away from the substrate 10 for supporting the mask plate are required, thereby saving preparation costs. The third isolation structure can be prepared and formed by using dark-colored materials, so that it can have a light-shielding effect and prevent light from crossing between adjacent third light-emitting units 116. The third isolation structure can have the same structure as the first isolation structure, or the same structure as the second isolation structure, which is not particularly limited in this application. When the third isolation structure 21 has the same structure as one of the first isolation structure 120 and the second isolation structure 15, it is electrically connected to the other through the transparent connection part 13.

[0120] The display panel 1 further includes a third driving circuit located in the second display area A2, for driving the second light emitting unit 115 to emit light, and the second light emitting unit 115 is electrically connected to the third driving circuit through an electrode wiring. In a feasible embodiment, the shape of the orthographic projection of the first light emitting unit 114 on the substrate 10 is at least one of an ellipse, a circle, a polygon, and a rounded polygon.

[0121] Specifically, when the orthographic projection of the first light emitting unit 114 on the substrate 10 is circular or elliptical, the diffraction of light in the first display area A1 can be reduced. When the first light emitting unit 114 needs to be designed in a rectangular shape due to display requirements, in order to reduce the diffraction of light by the straight edge, the arc corners can be chamfered to form a rounded rectangle.

[0122] The display panel provided in the present application also includes an encapsulation layer 18, such as Fig.14 and Fig.15 As shown, it is formed on the side of the light emitting unit away from the substrate and corresponds to the light emitting unit one by one, and adjacent encapsulation layers 18 are arranged at intervals.

[0123] In a possible implementation, Figure 1 and Fig.16 As shown, the display panel 1 further includes a frame area B, and the isolation structure 12 further includes a fourth isolation structure 22 located in the frame area B. The fourth isolation structure 22 is continuously arranged with the second isolation structure 15 , and the fourth isolation structure 22 includes a vent hole 221 .

[0124] In the above embodiment, in the frame area B of the display panel 1, the isolation structure 12 includes a fourth isolation structure 22 located in the frame area B of the display panel 1, and the fourth isolation structure 22 is integrally formed with the second isolation structure 15, thereby simplifying the manufacturing process. The fourth isolation structure 22 includes a vent hole 221, thereby improving the air permeability between the fourth isolation structure 22 and the contact film layer below, improving the problem of lifting the fourth isolation structure 22 due to poor air permeability, so that the fourth isolation structure 22 is separated from the film layer below, thereby helping to improve the product yield.

[0125] Specifically, the arrangement of the light-transmitting portions 221 is the same as the arrangement of the light-transmitting holes 153 .

[0126] The fourth isolation structure 22 is formed with air holes 221 arranged in the same manner as the light-transmitting holes 153 in the second isolation structure 15. The light-transmitting holes 153 and the air holes 221 are also prepared using the same process, so that the fourth isolation structure 22 and the second isolation structure 15 are prepared using the same process, which helps to simplify the preparation process.

[0127] Specifically, the frame area includes a second shielding portion 23 , which is disposed on one side of the substrate 10 , and an orthographic projection of the second shielding portion 23 on the substrate 10 covers an orthographic projection of the vent hole 221 on the substrate 10 .

[0128] In the above embodiment, in order to ensure the shielding effect of the border area B and reduce the mutual interference between the signal in the touch layer and the signal in the substrate 10 at the air hole 221, a second shielding portion 23 is formed at a position opposite to the air hole 221 to shield the signal, thereby improving the mutual interference between the signal in the touch layer and the signal in the substrate 10.

[0129] In a possible implementation, Fig.17 and Fig.18 As shown, the second shielding part 23 is disposed in the same layer as the first shielding part 16. That is, the second shielding part 23 and the first shielding part 16 are prepared by the same process, thereby simplifying the preparation process and reducing the preparation cost.

[0130] In a possible implementation, Fig.17 and Fig.18 As shown, the second shielding parts 23 are arranged one by one with the air holes 221, and the second shielding parts 23 corresponding to adjacent air holes 221 are arranged at intervals. On the one hand, the second shielding parts 23 and the first shielding parts 16 can be prepared and formed by the same process, and on the other hand, while achieving a good shielding effect, the material of the second shielding part 23 can be saved, thereby saving costs.

[0131] In a possible implementation, Fig.17 and Fig.18As shown, the border region B further includes a dam 24 . The dam 24 is located on one side of the substrate 10 . The dam 24 and the fourth isolation structure 22 are arranged in the same layer and spaced apart.

[0132] In the above embodiment, the dam 24 can be used to prevent the film layer from flowing outward, thereby improving the preparation yield and uniformity of the film thickness of the film layer. Specifically, the display panel 1 may further include an organic encapsulation layer 25 and an inorganic encapsulation layer 26 located on the side of the encapsulation layer 18 away from the substrate 10. The organic encapsulation layer 25 has a strong fluidity, and the dam 24 can be used to prevent the organic encapsulation layer 25 from flowing toward the peripheral side of the display panel 1, thereby improving the preparation yield and uniformity of the film thickness of the organic encapsulation layer 25.

The orthographic projection of the first shielding portion 16 on the substrate 10 covers the orthographic projection of the light-transmitting hole 153 on the substrate 10. Specifically, the first shielding portion 16 can be formed between the isolation structure 12 and the substrate 10, and the first shielding portion 16 is in contact with the isolation structure 12. The first shielding portion 16 can effectively shield the signal interference between the film layer on the side of the isolation structure 12 away from the substrate 10 and the substrate 10. Specifically, the display panel 1 may include a touch layer, which is located on the side of the isolation structure 12 away from the substrate 10. The touch layer includes touch electrodes. The substrate 10 is provided with signal wiring for driving the light-emitting unit 11 to display. By providing the first shielding portion 16 at the light-transmitting hole 153, the mutual interference between the touch electrodes and the signal wiring in the substrate 10 at the light-transmitting hole 153 can be reduced, thereby improving the performance of the display panel 1.

[0136] In a feasible implementation manner, the first shielding portion 16 is electrically connected to the isolation structure 12 , so as to achieve the continuity of the isolation structure 12 in the first display sub-area A21 , thereby facilitating signal transmission.

The isolation structure 12 includes a second isolation structure 1512, and the second isolation structure 1512 includes a fifth isolation portion 154.

The second conductive layer 1542 is located on the side of the second insulating layer 1541 away from the substrate 10. The second insulating layer 1541 is in direct contact with the substrate 10 and the side of the first electrode 111 of the second light-emitting unit 115 away from the substrate 10.

Therefore, when preparing second light-emitting units 115 of various colors, the film layers in the second light-emitting units 115 of one color can be formed on the entire surface first, and then the second light-emitting units 115 of the color are formed at the designated second openings 152 by etching, and the second openings 152 for forming second light-emitting units 115 of other colors are exposed. Second light-emitting units 115 of different colors are prepared in multiple times, and the above preparation process does not require the use of a mask plate, and at the same time, it is not necessary to prepare the pixel definition layer 14 and the support column located on the side of the pixel definition layer 14 away from the substrate 10 for supporting the mask plate, thereby saving preparation costs. The second isolation structure 1512 can be prepared and formed using a dark material, so that it can have a light-shielding effect and prevent cross-light between adjacent second light-emitting units 115.

[0145] In the above embodiment, the display panel 1 includes a pixel definition layer 14 and an isolation structure 12 located on a side of the pixel definition layer 14 away from the substrate 10. The pixel definition layer 14 is used to define the light-emitting unit 11. The second isolation structure 1512 includes a seventh isolation portion 156 directly in contact with a surface of the side of the pixel definition layer 14 away from the substrate 10, and the seventh isolation portion 156 includes a conductive material.

The second functional layer 1562 is located on the side of the first functional layer 1561 away from the substrate 10. The first functional layer 1561 includes a conductive material. The first shielding portion 16 and the second electrode 113 of the second light-emitting unit 115 are respectively connected to the first functional layer 1561.

[0147] In the above embodiment, the material of the first functional layer 1561 can be metal, such as molybdenum, and the material of the second functional layer 1562 can be metal, such as aluminum. The first functional layer 1561 can protect the second functional layer 1562 and prevent the second functional layer 1562 from being oxidized by water and oxygen on the substrate 10 side.

[0148] In a possible implementation, Fig. 20 As shown, the second isolation structure 1512 also includes an eighth isolation portion 157, which is located on the side of the seventh isolation portion 156 away from the substrate 10, and the orthographic projection of the seventh isolation portion 156 on the substrate 10 is located within the orthographic projection of the eighth isolation portion 157 on the substrate 10.

[0149] In the above embodiment, the second isolation structure 1512 includes a seventh isolation portion 156 and an eighth isolation portion 157, and the orthographic projection of the seventh isolation portion 156 on the substrate 10 is located within the orthographic projection of the eighth isolation portion 157 on the substrate 10, so that when preparing second light-emitting units 115 of various colors, the various film layers in the second light-emitting units 115 of one color can be formed on the entire surface first, and then the second light-emitting units 115 of the color are formed at the designated second openings 152 by etching, and the second openings 152 for forming second light-emitting units 115 of other colors are exposed. Second light-emitting units 115 of different colors are prepared in multiple times, and the above preparation process does not require the use of a mask plate, and at the same time, it is not necessary to prepare the pixel definition layer 14 and the support column located on the side of the pixel definition layer 14 away from the substrate 10 for supporting the mask plate, thereby saving preparation costs. The second isolation structure 1512 can be prepared and formed using a dark material, so that it can have a light-shielding effect and prevent cross-light between adjacent second light-emitting units 115.

[0150] In a feasible implementation manner, the first shielding portion 16 and the first functional layer 1561 are arranged in a direction parallel to the plane where the substrate 10 is located and contact each other, and the orthographic projection of the second functional layer 1562 on the substrate 10 covers a portion of the orthographic projection of the first shielding portion 16 on the substrate 10; or Fig. 20 As shown, the orthographic projection of the second functional layer 1562 on the substrate 10 does not overlap with the orthographic projection of the first shielding portion 16 on the substrate 10 .

[0151] In the above embodiment, the first shielding part 16 and the side wall of the first functional layer 1561 are in contact with each other, thereby realizing the electrical connection between the first shielding part 16 and the first functional layer 1561. And a part of the area in the first shielding part 16 is located between the second functional layer 1562 and the pixel definition layer 14, that is, the orthographic projection of the second functional layer 1562 on the substrate 10 covers a part of the orthographic projection of the first shielding part 16 on the substrate 10, so that the contact part between the first functional layer 1561 and the first shielding part 16 can be protected by the second functional layer 1562, reducing the influence of subsequent process on the above contact part. At the same time, when the material of the second functional layer 1562 is metal, the contact resistance between the first shielding part 16 and the first functional layer 1561 can be further reduced.

[0152] In a possible implementation, Fig.21 As shown, the first shielding part 16 contacts the side of the pixel definition layer 14 away from the substrate 10, and the first functional layer 1561 covers the edge of the first shielding part 16; the orthographic projection of the second functional layer 1562 on the substrate 10 covers a part of the orthographic projection of the first shielding part 16 on the substrate 10. Thus, the electrical connection between the first shielding part 16 and the first functional layer 1561 can be achieved. The contact part between the first functional layer 1561 and the first shielding part 16 can be protected by the second functional layer 1562.

The first functional layer 1561 covers the edge of the first shielding portion 16, that is, the first functional layer 1561 contacts the side wall of the first shielding portion 16 facing the second opening 152, and at the same time, the first functional layer 1561 contacts the surface of the first shielding portion 16 away from the substrate 10, which can increase the contact area between the first functional layer 1561 and the first shielding portion 16, so as to improve the connection stability between the two and reduce the contact resistance between the two.

[0155] In the above embodiment, the first shielding portion 16 and the first functional layer 1561 are formed by one process and have an integrated structure. In this case, the connection stability between the two is stronger, and the preparation process can be saved and the preparation cost can be reduced. In this case, the material of the first functional layer 1561 is the same as that of the first shielding portion 16, and both are transparent conductive materials.
