In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

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.

[0077] With the development of informatization, the demand for intelligent, thin, fast and light display devices is increasing. In addition to meeting the display needs, display devices such as mobile phones and computers also need to meet the touch needs to meet the diverse needs of display devices. In view of this, how to integrate the touch function in the display device has become the research direction of many manufacturers.

[0078] First, see Figure 1 and Figure 2 The embodiment of the present application provides a display panel, including a substrate 10, an isolation structure 20, a light-emitting functional layer 30, a first electrode layer 40 and a light adjustment unit 60. The isolation structure 20 is arranged on one side of the substrate 10. The isolation structure 20 includes a plurality of isolation units D1 arranged at intervals. The isolation units D1 enclose at least one opening structure 21. The light-emitting functional layer 30 is arranged on one side of the substrate 10. The light-emitting functional layer 30 includes a light-emitting structure 31 arranged corresponding to the opening structure 21.

[0079] The first electrode layer 40 is disposed on the side of the light-emitting functional layer 30 away from the substrate 10, and the first electrode layer 40 includes a first electrode 41 disposed corresponding to the opening structure 21. The light adjustment part 60 is disposed on one side of the substrate 10, and the orthographic projection of the light adjustment part 60 on the substrate 10 is at least partially located between the orthographic projections of adjacent isolation units D1 on the substrate 10.

[0080] The substrate 10 mainly plays a supporting role, and other film layers are stacked on the substrate 10 in sequence. The stacking arrangement mentioned here means that other film layers are arranged in sequence along the thickness direction X of the substrate 10, wherein the substrate 10 may include multiple film layer structures. The specific film layer structure composition of the film layer is not limited in the embodiment of the present application. And the thickness direction X of other film layers located on one side of the substrate 10 is usually consistent with the thickness direction X of the substrate 10 itself. Therefore, for the convenience of expression, the thickness direction X of the substrate 10 or the thickness direction X of other film layers mentioned later in the embodiment of the present application are all indicated in the same direction.

[0081] The light-emitting functional layer 30 and the isolation structure 20 are located on the same side of the substrate 10, and the light-emitting functional layer 30 includes a light-emitting structure 31 arranged corresponding to the opening structure 21. The "light-emitting structure 31 is arranged corresponding to the opening structure 21" mentioned here means that the orthographic projection of the light-emitting structure 31 on the substrate 10 is at least partially located within the orthographic projection of the opening structure 21 on the substrate 10. The light-emitting structure 31 can be located within the opening structure 21, or can also be located on the side of the opening structure 21 facing the substrate 10, and the embodiment of the present application does not limit this.

[0082] The light emitting structures 31 include but are not limited to a red light emitting structure 31 for emitting red light, a green light emitting structure 31 for emitting green light, and a blue light emitting structure 31 for emitting blue light. Each light emitting structure 31 may include a stacked hole injection layer (HIL), a hole transport layer (HTL), a light emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL).

[0083] The first electrode layer 40 is located on the side of the light-emitting functional layer 30 facing away from the substrate 10. Similar to the light-emitting functional layer 30, the first electrode layer 40 also includes a plurality of first electrodes 41 arranged corresponding to the opening structure 21, that is, the orthographic projection of the first electrode 41 on the substrate 10 is at least partially located within the orthographic projection of the opening structure 21 on the substrate 10. Optionally, the display panel further includes a second electrode layer 50 located on the side of the light-emitting functional layer 30 facing the substrate 10, and the second electrode layer 50 is provided with a second electrode 51. The number of the second electrodes 51 is multiple, and the multiple second electrodes 51 are arranged corresponding to the multiple light-emitting structures 31. The first electrode 41 and the second electrode 51 jointly drive the light-emitting structure 31 to emit light. Exemplarily, the first electrode 41 is a cathode, and the second electrode 51 is an anode.

[0084] The isolation structure 20 includes a plurality of isolation units D1 disposed at intervals, and a certain distance exists between different isolation units D1, so as to achieve mutual insulation between different isolation units D1. Furthermore, the isolation units D1 at least enclose one opening structure 21, and the light-emitting structure 31 and the first electrode 41 can be disposed corresponding to the opening structure 21. The isolation structure 20 can enable the light-emitting functional layer 30 to form a plurality of light-emitting structures 31 disposed at intervals without the need for a fine metal mask.

[0085] Specifically, taking the preparation of the red light-emitting structure 31 before the preparation of the green light-emitting structure 31 as an example, since the precision metal mask is eliminated, the red light-emitting material corresponding to the red light-emitting structure 31 will first fall into each opening structure 21, and then the red light-emitting material in a part of the opening structure 21 will be selectively etched away, and the red light-emitting material in a part of the opening structure 21 will be retained to form the red light-emitting structure 31. After that, the green light-emitting material corresponding to the green light-emitting structure 31 will fall into each opening structure 21, and then the green light-emitting material in a part of the opening structure 21 will be selectively etched away, and the green light-emitting material in a part of the opening structure 21 will be retained to form the green light-emitting structure 31.

[0086] Similarly, due to the existence of the isolation structure 20, the first electrode layer 40 may also include a plurality of first electrodes 41 arranged corresponding to the opening structure 21, that is, the plurality of first electrodes 41 may be arranged corresponding to the plurality of light-emitting structures 31 to achieve driving control of the light-emitting structures 31. For the plurality of opening structures 21 enclosed by the same isolation unit D1, the plurality of first electrodes 41 arranged corresponding to the plurality of opening structures 21 are electrically connected to the isolation unit D1.

[0087] On this basis, in some embodiments, a conductive material may be provided in the isolation unit D1, and the first electrode 41 may be in contact with and electrically connected to the corresponding isolation unit D1, so that the isolation unit D1 and one or more first electrodes 41 corresponding to the isolation unit D1 can together constitute a touch unit D2. For example, multiple first electrodes 41 electrically connected to the same isolation unit D1 and the isolation unit D1 form a touch unit D2. In other words, in addition to being used to satisfy the drive control of the light-emitting structure 31, the first electrode 41 is also used to constitute a touch unit D2 for realizing a touch function.

[0088] Specifically, since the isolation unit D1 can be in contact with the first electrode 41 and electrically connected, during the use of the display panel, the control module such as the driver chip IC can transmit a power signal to the isolation unit D1 in certain specific time zones, and the isolation unit D1 transmits the corresponding power signal to the first electrode 41 to meet the light-emitting driving function of the first electrode 41 for the light-emitting structure 31. In other time zones, the driver chip IC can transmit a specific touch signal to the touch unit D2 composed of the first electrode 41 and the isolation unit D1, so that the display panel can realize the touch function. That is, in different time zones, the driver chip IC can transmit a power signal or a touch signal to the first electrode 41 respectively, so that the display panel can realize the display and touch functions at the same time, and realize the time-sharing and zone-sharing control of the display and touch functions.

[0089] In some embodiments, one isolation unit D1 and at least one first electrode electrically connected to the isolation unit D1 form a touch unit D2 , and adjacent touch units D2 are spaced apart.

[0090] It should be noted that, in this embodiment, the touch function implemented by the multiple touch units D2 may be a self-capacitive touch function.

[0091] In the above embodiment, the isolation unit D1 and the first electrode 41 can be reused as a touch unit. In another embodiment, a plurality of isolation units D1 arranged at intervals can also realize independent control of the first electrode 41. For example, the first electrodes 41 electrically connected to the same isolation unit D1 have the same voltage, and the first electrodes 41 electrically connected to different isolation units D1 have different voltages, so that the first electrodes 41 in different areas can have different voltages, thereby realizing the independent control of the first electrodes 41 in different areas.

[0092] In the embodiment of the present application, the isolation structure 20 is patterned so that the isolation structure 20 can be divided into a plurality of isolation units D1 with insulating intervals. On this basis, the isolation unit D1 and the corresponding first electrode 41 can together constitute a touch unit D2. By transmitting different types of signals to the first electrode 41 in different time zones, the display panel can achieve time-sharing and zone-based control of the display and touch functions without the need for an additional touch layer, thereby helping to reduce the overall thickness of the display panel and contributing to a thin and light design of the display panel.

[0093] However, since there is a certain distance between the isolation units D1, there will be areas with isolation units D1 and areas without isolation units D1 in the display panel, and there will usually be reflective materials in these two areas, and the distribution of the reflective materials will be different. This will easily lead to differences in the light reflectivity corresponding to different areas of the display panel, which may easily cause the risk of the pattern of the isolation structure 20 being visible when the display panel is turned off.

[0094] In view of this, the embodiment of the present application further adds a light adjustment unit 60, which is mainly used to compensate for or absorb and block ambient light. By placing the orthographic projection of the light adjustment unit 60 on the substrate 10 between the orthographic projections of adjacent isolation units D1 on the substrate 10, the light adjustment unit 60 can adjust the light incident between adjacent touch units D2. For example, the light adjustment unit 60 absorbs, blocks or reflects the incident light. Whether the light adjustment unit 60 absorbs, blocks or reflects the incident light can be determined based on whether the isolation unit D1 absorbs or reflects the incident light. In this way, the difference in light between the area where the isolation unit D1 is provided and the area where the isolation unit D1 is not provided in the display panel can be reduced, thereby improving the performance of the display panel.

[0095] It should be noted that the light adjustment unit 60 can have various forms, wherein the light adjustment unit 60 can achieve the light shielding effect by absorbing at least part of the light. Alternatively, the light adjustment unit 60 can adjust the light reflectivity at the corresponding position of the display panel by means of materials such as metal, so that the difference in light reflectivity at different positions is reduced, thereby achieving compensation adjustment of the light.

[0096] In addition, the light adjustment portion 60 can have a variety of position forms, for example, at least a portion of the light adjustment portion 60 can be located on the side of the isolation structure 20 facing away from the substrate 10, or at least a portion of the light adjustment portion 60 can be located in the same film layer as the isolation structure 20, or at least a portion of the light adjustment portion 60 can also be located on the side of the isolation structure 20 facing the substrate 10, and the embodiments of the present application are not limited to this.

[0097] In some embodiments, both the isolation unit D1 and the light adjustment unit 60 have light shielding materials, or both the isolation unit D1 and the light adjustment unit 60 have light reflecting materials. In this way, the gap between the isolation unit D1 and the adjacent isolation unit D1 has light shielding properties or light reflecting properties, reducing the difference between the area where the isolation unit D1 is provided and the area where the isolation unit D1 is not provided in the display panel, and reducing the risk of the pattern of the isolation structure 20 being visible when the display panel is turned off.

[0098] In some embodiments, Figure 1 and Figure 2 As shown, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 which are sequentially stacked in a direction away from the substrate 10 , and the orthographic projection of the first isolation portion 22 on the substrate 10 is located within the orthographic projection of the second isolation portion 23 on the substrate 10 .

[0099] The specific size and shape of the first isolation portion 22 and the second isolation portion 23 are not limited in the embodiment of the present application. For example, the longitudinal section of the isolation structure 20 can be I-shaped, T-shaped, or inverted trapezoidal. This design helps to disconnect the light-emitting material and the electrode material at the edge of the isolation structure 20 during the preparation of the light-emitting functional layer 30 and the first electrode layer 40, thereby realizing the preparation and mutual separation of the light-emitting structure 31 and the first electrode 41 corresponding to different opening structures 21 without the need for a fine metal mask.

[0100] The embodiment of the present application does not limit the material composition of the first isolation portion 22 and the second isolation portion 23. The first isolation portion 22 and the second isolation portion 23 may both include conductive materials, or the first isolation portion 22 includes conductive materials, while the second isolation portion 23 includes insulating materials, as long as the first electrode 41 can achieve signal transmission with the aid of at least one of the first isolation portion 22 and the second isolation portion 23.

[0101] In some embodiments, the first isolation portion 22 includes a conductive material, and the first electrode 41 is electrically connected to the first isolation portion 22 .

[0102] The first electrode 41 is electrically connected to the first isolation portion 22 , wherein the first electrode 41 may be in direct contact with the first isolation portion 22 , or the first electrode 41 may be electrically connected to the first isolation portion 22 with the aid of other conductive structures, which is not limited in the embodiments of the present application.

[0103] In the embodiment of the present application, by setting a conductive material in the first isolation portion 22, the display panel can use the first isolation portion 22 to transmit the power signal to the first electrode 41, thereby meeting the needs of signal transmission and facilitating the time-sharing and zone-sharing driving of touch and display in the display panel.

[0104] In some embodiments, see Figure 1 and Figure 3 The isolation structure 20 further includes a third isolation portion 24 located on a side of the first isolation portion 22 facing the substrate 10 . The third isolation portion 24 includes a conductive material and is electrically connected to the first isolation portion 22 .

[0105] In the thickness direction X, the isolation structure 20 includes at least a first isolation portion 22, a second isolation portion 23, and a third isolation portion 24. The embodiment of the present application does not limit the size and shape of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24. Exemplarily, the orthographic projection of the first isolation portion 22 on the substrate 10 is located within the orthographic projection of the third isolation portion 24 on the substrate 10, that is, the longitudinal cross-section of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 is in an I-shape.

[0106] Similar to the first isolation portion 22, the third isolation portion 24 also includes a conductive material, and the first electrode 41 can directly contact the third isolation portion 24 to achieve electrical connection with the first isolation portion 22 by means of the third isolation portion 24. Optionally, the first electrode 41 is overlapped with the third isolation portion 24. Further, the first electrode 41 can be partially located on the side of the third isolation portion 24 away from the substrate 10, and the provision of the third isolation portion 24 helps to improve the reliability of the electrical connection between the first electrode 41 and the isolation structure 20.

[0107] In some embodiments, Figure 1 and Figure 2 As shown, the display panel further includes a plurality of connecting wires Z1 , and at least some of the different connecting wires Z1 are electrically connected to different isolation units D1 .

[0108] The connection line Z1 is electrically connected to the isolation unit D1 to transmit a touch signal to the touch unit D2 in a specific time zone, or to transmit a power signal to the first electrode 41 in the touch unit D2 in a specific time zone, so as to meet the time-sharing and zone-sharing driving of the display and touch in the display panel. The connection line Z1 can be arranged in contact with the first isolation part 22 in the isolation unit D1, or the connection line Z1 can also be arranged in contact with the second isolation part 23 in the isolation unit D1, or the connection line Z1 can also be arranged in contact with the third isolation part 24 in the isolation unit D1, as long as the connection line Z1 can be in contact with the structure in the touch unit D2 for electrical connection with the first electrode 41. For example, the connection line Z1 can be arranged in contact with the isolation structure 20. In some optional embodiments, the connection line Z1 is arranged in contact with the first isolation part 22. Or, in other optional embodiments, the connection line Z1 is arranged in contact with the first isolation part 23.

[0109] In an embodiment of the present application, at least some of the different connecting lines Z1 are electrically connected to different isolation units D1, so that during the display or touch process, different power signals or touch signals can be transmitted to different isolation units D1 with the help of different connecting lines Z1, thereby realizing zoned control of the display function and the touch function, and improving the display or touch accuracy of the display panel.

[0110] It should be noted that the number of connection lines Z1 corresponding to one isolation unit D1 may be one or more, and the number of connection lines Z1 corresponding to different isolation units D1 may be the same or different, which is not limited in the embodiment of the present application.

[0111] In addition, the present application embodiment does not limit the layout design of the connection line Z1 in the display panel. Figure 4 and Figure 5 The light adjustment portion 60 includes at least a portion of the connecting line Z1 that is located between adjacent isolation units D1 when projected on the substrate 10 .

[0112] The orthographic projection of at least part of the connection line Z1 on the substrate 10 is located between the orthographic projections of the connected isolation units D1 on the substrate 10, so that at least part of the connection line Z1 can be reused as the light adjustment unit 60. Specifically, the connection line Z1 may include metal materials such as copper, aluminum and titanium, and the orthographic projection of at least part of the connection line Z1 on the substrate 10 is set between the orthographic projections of the connected isolation units D1 on the substrate 10, so that the light reflectivity of the area corresponding to the adjacent touch units D2 in the display panel can be adjusted by means of the connection line Z1, so as to reduce the difference in light reflectivity corresponding to different areas, which helps to reduce the risk of the isolation unit D1 being visible when the display panel is in the off state.

[0113] Furthermore, the embodiment of the present application can use the connecting wire Z1 to adjust the light in the area of ​​the display panel between adjacent isolation units D1, which can improve the display uniformity without the need for additional metal materials, and help reduce the manufacturing cost of the display panel. At the same time, at least part of the connecting wire Z1 can be arranged to avoid the light emitting structure 31, thereby improving the display effect of the display panel.

[0114] The specific position of the connection line Z1 whose orthographic projection is located between adjacent isolation units D1 is not limited in the embodiment of the present application. For example, the connection line Z1 whose orthographic projection is located between adjacent isolation units D1 can be arranged on the side of the isolation structure 20 away from the substrate 10, or can be arranged on the side of the light-emitting functional layer 30 facing the substrate 10.

[0115] In some embodiments, at least part of the connection line Z1 is overlapped with the orthographic projection of the isolation unit D1 on the substrate 10 , that is, at least part of the connection line Z1 is arranged on the side of the isolation unit D1 away from the substrate 10 .

[0116] In the embodiment of the present application, since part of the connecting line Z1 is set corresponding to the isolation unit D1, the connecting line Z1 can be extended along the isolation unit D1, so that the orthographic projection of the connecting line Z1 on the substrate 10 and the orthographic projection of the light-emitting structure 31 on the substrate 10 are staggered, thereby reducing the influence of the connecting line Z1 on the light emitted by the light-emitting structure 31 and improving the display effect of the display panel.

[0117] In some embodiments, see Figure 6 The display panel further includes a virtual wiring Z3 arranged parallel to and insulated from the connecting wire Z1. Among the multiple connecting wires Z1 and the virtual wiring Z3 arranged parallel to each other, the spacing between any two adjacent wirings is consistent.

[0118] The virtual line Z3 may include the same material as the connecting line Z1, but unlike the connecting line Z1, the virtual line Z3 is not electrically connected to the isolation unit D1, so the virtual line Z3 and the connecting line Z2 are insulated from each other. Further, the virtual line Z3 may not be electrically connected to any other signal, that is, no signal is transmitted in the virtual line Z3.

[0119] The virtual routing line Z3 can be interspersed between multiple connecting lines Z1, and the extension direction of the virtual routing line Z3 can be consistent with the extension direction of the connecting line Z1, so that the two can be arranged side by side. On this basis, among the multiple connecting lines Z1 and virtual routing lines Z3 arranged side by side, the spacing between any two adjacent routing lines is consistent. The "any two adjacent routing lines" mentioned here can be two connecting lines Z1, or it can also be a connecting line Z1 and a virtual routing line Z3, or it can also be two virtual routing lines Z3, as long as there are no other connecting lines and virtual routing lines Z3 between the two routing lines.

[0120] In an embodiment of the present application, a virtual routing line Z3 is added in the display panel, and the spacing between any two adjacent routing lines is made consistent among the multiple connecting lines Z1 and the virtual routing line Z3 arranged side by side. This allows the arrangement density of the conductor materials constituting the connecting lines Z1 and the virtual routing lines Z3 to be consistent in different areas of the display panel, thereby reducing the difference in light reflectivity corresponding to different areas, which helps to reduce the risk of the isolation unit D1 being visible when the display panel is in the off state.

[0121] It should be noted that in Figure 6 In the embodiment, the orthographic projections of the connecting wire Z1 and the virtual line Z3 on the substrate may overlap with the light-emitting structure. On this basis, in order to reduce the influence of the connecting wire Z1 and the virtual line Z3 on the light-emitting effect, the connecting wire Z1 and the virtual line Z3 can be arranged on the side of the light-emitting structure facing the substrate. In addition, the positions of the connecting wire Z1 and the virtual line Z3 can also be adjusted so that the orthographic projections of the connecting wire Z1 and the virtual line Z3 on the substrate do not overlap with the light-emitting structure.

[0122] The embodiment of the present application does not limit the type of signal transmitted inside the connection line Z1. Optionally, the connection line Z1 includes a power signal line, which is used to provide a power signal to the first electrode 41 to control whether the light-emitting structure 31 emits light. Or in some embodiments, the first electrode 41 is electrically connected to the isolation unit D1 to form a touch unit D2, and the connection line Z1 includes a touch signal line. The touch signal line is used to provide a touch signal to the touch unit D2 to realize the touch function of the display panel.

[0123] The isolation unit D1 includes a transparent material and / or a reflective material. The embodiment of the present application does not limit the material composition of the first isolation portion 22 and the second isolation portion 23. Optionally, the first isolation portion includes a transparent or reflective material, and / or the second isolation portion includes a transparent or reflective material. In some specific embodiments, the first isolation portion 22 includes a reflective material, and the second isolation portion 23 includes a translucent material. For example, the material of the first isolation portion 22 is aluminum, and the material of the second isolation portion 23 is a translucent metal oxide; or, both the first isolation portion 22 and the second isolation portion 23 include a reflective material. For example, the material of the first isolation portion 22 is aluminum, and the material of the second isolation portion 23 is titanium.

[0124] In some embodiments, Figure 1 and Figure 2 As shown, the light adjustment portion 60 includes a light shielding portion 61 , and the orthographic projection of at least a portion of the structure of the light shielding portion 61 on the substrate 10 is located between the orthographic projections of adjacent isolation units D1 on the substrate 10 .

[0125] The light shielding portion 61 may include a light shielding material, and optionally, the light shielding material may be a black material. The specific material composition of the light shielding portion 61 is not limited in the embodiment of the present application. Exemplarily, the light shielding portion 61 includes an organic material. Preferably, the light shielding portion 61 includes a light shielding material.

[0126] In the embodiment of the present application, by arranging the orthographic projection of at least part of the structure of the shading portion 61 on the substrate 10 to be located between the orthographic projections of adjacent isolation units D1 on the substrate 10, the shading portion 61 is used to absorb the light incident on the display panel corresponding to the adjacent isolation units D1, which also helps to improve the uniformity of the display panel.

[0127] The specific position of the light shielding portion 61 in the display panel is not limited in the embodiment of the present application. Optionally, at least part of the light shielding portion 61 is located in the same film layer as the isolation structure 20, for example, at least part of the light shielding portion 61 is located in the same film layer as the first isolation portion 22, that is, at least part of the light shielding portion 61 can be filled between the first isolation portions 22 corresponding to the adjacent isolation units D1, so that the light shielding portion 61 can fill the gap space formed by the adjacent isolation units D1, which is beneficial to the preparation of subsequent film layers.

[0128] In some embodiments, the display panel further includes a plurality of connection lines Z1 , at least some of the different connection lines Z1 are electrically connected to different isolation units D1 , and at least some of the connection lines Z1 are located on a side of the light shielding portion 61 facing the substrate 10 .

[0129] In the embodiment of the present application, at least part of the connecting line Z1 is located on the side of the shading portion 61 facing the substrate 10. In this case, at least part of the connecting line Z1 can be set in the same layer and material as the conductive material in the display panel, thereby improving the preparation efficiency of the display panel.

[0130] Alternatively, in some other embodiments, at least a portion of the light shielding portion 61 is located on a side of the isolation structure 20 facing away from the substrate 10 , that is, at least a portion of the light shielding portion 61 is located on a side of the second isolation portion 23 facing away from the substrate 10 .

[0131] In the embodiment of the present application, by setting at least a portion of the shading portion 61 on the side of the second isolation portion 23 away from the substrate 10, the shading portion 61 can cover at least a portion of the structure in the second isolation portion 23. Therefore, during the preparation of the shading portion 61, it is necessary to set the size of the shading portion 61 to exceed the side of the second isolation portion 23 away from the substrate 10, so that the shading portion 61 can be better filled between adjacent isolation units D1, thereby further improving the shading effect of the shading portion 61 on the area between adjacent touch units D2.

[0132] It should be noted that when the second isolation portion 23 includes a black material, the light regulating portion 60 may include a shading portion 61, that is, the shading portion 61 may be located between the orthographic projections of adjacent isolation units D1 on the substrate 10. The shading portion 61 absorbs at least part of the ambient light to reduce the risk of the isolation unit D1 being visible when the display panel is off.

[0133] In some optional embodiments, at least a portion of the light shielding portion 61 is located on the side of the isolation structure 20 facing away from the substrate 10, and the orthographic projection of the light shielding portion 61 on the substrate 10 overlaps with the orthographic projection of the isolation structure 20 on the substrate 10. This design allows the light shielding portion 61 to be located at the location of the isolation structure 20 and in the gap between adjacent isolation units D1 at the same time, thereby further reducing the difference in different areas and reducing the risk of the isolation unit D1 being visible when the display panel is off.

[0134] Optionally, the orthographic projection of the shading portion 61 on the substrate 10 covers the orthographic projection of the isolation structure 20 on the substrate 10. For example, if the isolation structure 20 does not have a shading function, the orthographic projection of the shading portion 61 on the substrate 10 covers the orthographic projection of the isolation structure 20 on the substrate 10, that is, the upper surface of the isolation structure 20 is covered with the shading portion 61, so that the region with the isolation structure 20 and the region without the isolation structure 20 have the same effect on light.

[0135] Optionally, if the isolation structure 20 has a light shielding function, a light shielding portion 61 may be provided in the gap between adjacent isolation units D1 , and the upper surface of the isolation structure 20 may not be covered by the light shielding portion 61 .

[0136] Optionally, when the second isolation portion 23 or the first isolation portion 22 includes a reflective material, the light adjustment portion 60 may include at least a portion of the connecting wires Z1 or other structures that can reflect light, that is, at least a portion of the connecting wires Z1 on the substrate 10 may be located between the orthographic projections of adjacent isolation units D1 on the substrate 10. The connecting wires Z1 may be used to adjust the light reflectivity of the area corresponding to the adjacent isolation units D1 in the display panel, thereby reducing the difference in light reflectivity corresponding to different areas, which helps to reduce the risk of the isolation units D1 being visible when the display panel is off.

[0137] In some embodiments, see Figure 7 , at least part of the connecting line Z1 is located on the side of the light shielding portion 61 facing away from the substrate 10 .

[0138] In the embodiment of the present application, at least part of the connection line Z1 can be arranged on the side of the light shielding portion 61 away from the substrate 10, so that the connection line Z1 can be formed after the isolation structure 20 and the light shielding portion 61 are prepared. Compared with the solution in which the connection line Z1 is located on the side of the isolation structure 20 facing the substrate 10, the connection line Z1 under this design will not occupy the space on the side of the isolation structure 20 facing the substrate 10, that is, the connection line Z1 will not be arranged on the same layer as other wiring structures on the side of the isolation structure 20 facing the substrate 10, thereby reducing the risk of too small distance between adjacent wirings, reducing the wiring density, and improving the transmission reliability of wiring signals inside the display panel.

[0139] It should be noted that the connecting wire Z1 needs to contact part of the structure in the isolation unit D1 to meet the needs of signal transmission. On this basis, the connecting wire Z1 can contact the isolation unit D1 in a variety of ways, and the embodiment of the present application does not limit this. In some optional embodiments, the light shielding portion 61 is provided with a first via hole, and at least part of the connecting wire Z1 is connected to the isolation unit D1 via the first via hole.

[0140] The existence of the first via hole can meet the contact requirements between the connecting wire Z1 and the isolation unit D1. The first via hole can be set along the thickness direction X through the shading portion 61. With the help of the first via hole, the connecting wire Z1 can achieve contact with the isolation unit D1, thereby meeting the signal transmission requirements for the isolation unit D1 and the first electrode 41, and realizing time-sharing and partitioned driving of the display and touch functions in the display panel.

[0141] Furthermore, in some embodiments, the second isolation portion 23 is provided with a second via hole conductively connected to the first via hole, and at least a portion of the connection line Z1 is electrically connected to the first isolation portion 22 via the first via hole and the second via hole.

[0142] As can be seen from the foregoing, the first isolation portion 22 may include a conductive material, and the second isolation portion 23 may include an insulating material. On this basis, in order to meet the needs of signal transmission, the connection line Z1 needs to be arranged in contact with the first isolation portion 22. In view of this, the embodiment of the present application adds a second via hole in the isolation unit D1, and the connection line Z1 can achieve contact connection with the first isolation portion 22 by means of the first via hole and the second via hole, so as to meet the signal transmission needs of the isolation unit D1 and the first electrode 41, and realize the time-sharing and partitioning driving of the display and touch functions in the display panel.

[0143] In some embodiments, see Figure 8 The display panel further includes a protection layer 90 located on a side of the connecting line Z1 away from the substrate 10 .

[0144] The protective layer 90 covers the connection line Z1, and the existence of the protective layer 90 can play a certain shielding role, thereby reducing the influence of other film layers inside the display panel on the connection line Z1, and improving the reliability of signal transmission inside the connection line Z1. Among them, the protective layer 90 can have various forms, for example, the protective layer 90 can include a plurality of protective parts arranged at intervals, and the plurality of protective parts are arranged corresponding to the plurality of connection lines Z1 to achieve separate protection of different connection lines Z1.

[0145] Or in some optional embodiments, the protection layer 90 covers both the connecting line Z1 and the light shielding portion 61 .

[0146] In an embodiment of the present application, the protective layer 90 can be a whole-surface structure, which can cover the connecting line Z1 and the shading portion 61 at the same time. This helps the protective layer 90 to better cover the connecting line Z1. At the same time, the protective layer 90 is provided in different areas of the display panel, thereby reducing the impact of the protective layer 90 on the display uniformity and improving the display uniformity of the display panel.

[0147] The embodiment of the present application also does not limit the thickness of the protective layer 90. Optionally, the thickness of the protective layer 90 is W, and W satisfies: 3nm≤W≤300nm. This design can minimize the impact of the protective layer 90 on the overall thickness of the display panel while meeting the protection needs of the protective layer 90, which helps to design the display panel to be thin and light.

[0148] In some embodiments, Figure 1 and Figure 2 As shown, the display panel further includes a first encapsulation layer 71 located on the side of the first electrode layer 40 away from the substrate 10 . The first encapsulation layer 71 includes a first encapsulation portion 711 arranged corresponding to the opening structure 21 . The protective layer 90 covers at least a portion of the first encapsulation portion 711 .

[0149] The first encapsulation layer 71 is located on the side of the first electrode layer 40 away from the substrate 10, that is, on the side of the light emitting surface of the light emitting structure 31. The first encapsulation layer 71 can play a role in encapsulating and protecting the light emitting structure 31. Due to the existence of the isolation structure 20, the prepared first encapsulation layer 71 can have a plurality of first encapsulation parts 711 corresponding to the light emitting structure 31 and located in the opening structure 21, and each first encapsulation part 711 can play a role in independently encapsulating each light emitting structure 31, thereby improving the encapsulation and protection effect of the light emitting structure 31.

[0150] Furthermore, the protective layer 90 covers at least part of the first encapsulation part 711 at the same time, and the presence of the protective layer 90 can further improve the encapsulation protection effect of the light emitting structure 31. The embodiment of the present application does not limit the material composition of the first encapsulation layer 71 and the protective layer 90. Exemplarily, the first encapsulation layer 71 includes an inorganic material.

[0151] In some embodiments, the display panel further includes a second encapsulation layer 72 located on a side of the protection layer 90 facing away from the substrate 10 .

[0152] The first encapsulation layer 71 and the second encapsulation layer 72 can be used together to play an encapsulation protection role. Optionally, the display panel also includes a third encapsulation layer 73 located on the side of the second encapsulation layer 72 away from the substrate 10. The first encapsulation layer 71, the second encapsulation layer 72 and the third encapsulation layer 73 together constitute a thin film encapsulation structure. Thereby further reducing the risk of water, oxygen, etc. invading the light-emitting structure 31, and improving the reliability of the display panel. The material composition of the second encapsulation layer 72 and the third encapsulation layer 73 is not limited in the embodiment of the present application. Optionally, the first encapsulation layer 71 and the third encapsulation layer 73 both include inorganic materials, and the second encapsulation layer 72 includes organic materials, so that the first encapsulation layer 71 and the second encapsulation layer 72 can limit the second encapsulation layer 72 to a certain extent, thereby improving the reliability of the structure.

[0153] In addition to the difference in materials, the second encapsulation layer 72 is different from the first encapsulation layer 71 in that the second encapsulation layer 72 is a continuous structure on the entire surface. On this basis, the embodiment of the present application sets the protective layer 90 between the first encapsulation layer 71 and the second encapsulation layer 72. Since the protective layer 90 can be a full-surface structure, the protective layer 90 can assist the first encapsulation layer 71 in limiting the second encapsulation layer 72, thereby improving the reliability of the encapsulation structure. Further optionally, the protective layer 90 includes an inorganic material, for example, the protective layer 90 includes silicon nitride, silicon oxide or silicon oxynitride, and the second encapsulation layer 72 includes an organic layer material.

[0154] In some embodiments, see Fig. 9The display panel further includes a driving chip IC, the connecting wires Z1 are connected to the driving chip IC, and in a direction M away from the driving chip IC, the number of the connecting wires Z1 correspondingly connected to the isolation unit D1 tends to gradually increase.

[0155] The driver chip IC can transmit the corresponding touch signal to the isolation unit D1 via the connection line Z1, and transmit the corresponding power signal to the first electrode 41 via the connection line Z1 and the isolation unit D1, so as to meet the time-sharing and partitioning driving of touch and display in the display panel.

[0156] Furthermore, the distances between at least some of the different isolation units D1 and the driver chip IC are different. On this basis, the lengths of the connection lines Z1 corresponding to at least some of the different isolation units D1 are different, which results in different resistance values ​​corresponding to different connection lines Z1. On this basis, if the number of connection lines Z1 corresponding to different touch units D2 is set to be the same, the resistance values ​​of the connection lines Z1 connected to different touch units D2 will be different, so that the signal strengths received by different touch units D2 are different, which easily leads to the risk of uneven display or poor touch.

[0157] In view of this, the embodiment of the present application adjusts the number of connection lines Z1 corresponding to at least some of the different isolation units D1, so that in the direction M away from the driver chip IC, the number of connection lines Z1 corresponding to the touch unit D2 tends to gradually increase. That is, the farther away from the driver chip IC, the more connection lines Z1 will be connected to the same isolation unit D1, so as to reduce the difference in resistance value of the connection lines Z1 corresponding to different touch units D2, reduce the difference in signal strength received by different touch units D2, and improve the reliability of display and touch.

[0158] In some optional embodiments, the resistance value of the connection line Z1 corresponding to the partial isolation unit D1 is R1, the resistance value of the connection line Z1 corresponding to the partial isolation unit D1 is R2, and R1 and R2 satisfy: -0.1≤(R1-R2) / R1≤0.1.

[0159] The “connection line Z1 corresponding to the isolation unit D1” mentioned in the embodiments of the present application refers to: the connection line Z1 electrically connected to the isolation unit D1. When the isolation unit D1 is electrically connected to only one connection line Z1, the resistance value of the connection line Z1 corresponding to the isolation unit D1 is the resistance value of the single connection line Z1; when the isolation unit D1 is electrically connected to multiple connection lines Z1 at the same time, the resistance value of the connection line Z1 corresponding to the isolation unit D1 is the resistance value jointly constructed by multiple connection lines Z1 in parallel.

[0160] In the embodiment of the present application, parameters such as the number of connecting lines corresponding to different isolation units D1 can be adjusted so that the difference in resistance value of the connecting line Z1 corresponding to different isolation units D1 is no more than 10%, thereby reducing the difference in signal strength received by different isolation units D1 and improving the reliability of display and touch.

[0161] Further optionally, in the direction M away from the driving chip IC, the number of connecting lines Z1 corresponding to the touch units D2 located in the nth row is a, and the number of connecting lines Z1 corresponding to the touch units D2 located in the first row is b, and n is a positive integer greater than 1; wherein a and b satisfy: a:b=n:1.

[0162] Generally, the resistance value corresponding to a single connection line Z1 is proportional to its own length, and the overall resistance value corresponding to multiple connection lines Z1 of the same length connected in parallel is inversely proportional to the number of connection lines Z1. Specifically, if the length of a single connection line Z1 corresponding to the isolation unit D1 located in the first row is L, the length of a single connection line Z1 corresponding to the isolation unit D1 located in the nth row is nL, and further, the resistance value of the single connection line Z1 corresponding to the isolation unit D1 located in the nth row is n times the resistance value of the single connection line Z1 corresponding to the isolation unit D1 located in the first row.

[0163] On this basis, the embodiment of the present application sets the number of connection lines Z1 corresponding to the isolation unit D1 located in the nth row to n times the number of connection lines Z1 corresponding to the isolation unit D1 located in the 1st row, so that when other conditions are the same, the resistance value of the multiple parallel connection lines Z1 corresponding to the touch electrodes in the nth row can be the same as or similar to the resistance value of the connection lines Z1 corresponding to the touch electrodes in the 1st row. In this way, the difference in resistance value of the connection lines Z1 corresponding to different isolation units D1 can be further reduced, the difference in signal strength received by different isolation units D1 can be reduced, and the reliability of display and touch can be improved.

[0164] In some embodiments, see Fig.10 and Fig.11 The display panel further includes a pixel definition layer 80 located on the side of the isolation structure 20 facing the substrate 10 . The pixel definition layer 80 includes a pixel defining portion 81 and a pixel opening 82 enclosed by the pixel defining portion 81 .

[0165] The pixel definition layer 80 includes a pixel defining portion 81 and a pixel opening 82, and the pixel opening 82 is arranged corresponding to the opening structure 21. For example, the orthographic projection of the pixel opening 82 on the substrate 10 can be located within the orthographic projection of the opening structure 21 on the substrate 10, and the light emitting structure 31 and a part of the structure in the first electrode 41 can be located within the pixel opening 82. In some embodiments, the light adjustment portion 60 includes a light reflecting portion Z2 located on the side of the pixel defining portion 81 facing the substrate 10, and the orthographic projection of the light reflecting portion Z2 on the substrate 10 is at least partially located between the orthographic projections of adjacent touch units D2 on the substrate 10.

[0166] The light reflecting part Z2 can be used to reflect ambient light. Optionally, the light reflecting part Z2 includes a conductive material, and the light reflecting part Z2 is located on the side of the pixel definition layer 80 facing the substrate 10, wherein the light reflecting part Z2 can be electrically connected to other conductive structures, or the light reflecting part Z2 can also be not electrically connected to other conductive structures, that is, during the use of the display panel, the inside of the light reflecting part Z2 can be used to transmit a specific signal, or the inside of the light reflecting part Z2 can also not transmit a signal, and the embodiment of the present application is not limited to this.

[0167] Furthermore, the orthographic projection of the light reflecting portion Z2 on the substrate 10 is at least partially located between the orthographic projections of adjacent isolation units D1 on the substrate 10, so that the light reflectivity of the area corresponding to the adjacent isolation units D1 in the display panel can be adjusted by means of the light reflecting portion Z2, thereby reducing the difference in light reflectivity corresponding to different areas, which helps to reduce the risk of the isolation unit D1 being visible when the display panel is off. The embodiment of the present application does not limit the internal material composition of the light reflecting portion Z2. Optionally, the light reflecting portion Z2 may include metal materials such as copper, aluminum, and titanium.

[0168] It should be noted that the embodiment of the present application is more suitable for the case where the isolation unit D1 is provided with a reflective structure, and the light reflecting portion Z2 is used to adjust the uniformity of the reflection of light in the area between the isolation unit D1 and the adjacent isolation unit D1, so as to reduce the risk of the touch unit D2 being visible when the display panel is off. Optionally, the first isolation portion includes a transparent or reflective material, and / or the second isolation portion includes a transparent or reflective material. In some specific embodiments, the first isolation portion 22 includes a reflective material, and the second isolation portion 23 includes a translucent material, for example, the material of the first isolation portion 22 is aluminum, and the material of the second isolation portion 23 is a translucent metal oxide; or, both the first isolation portion 22 and the second isolation portion 23 include a reflective material, for example, the material of the first isolation portion 22 is aluminum, and the material of the second isolation portion 23 is titanium.

[0169] In some embodiments, the display panel further includes a second electrode layer 50 located on the side of the light-emitting functional layer 30 facing the substrate 10, and the second electrode layer 50 includes a plurality of second electrodes 51 arranged corresponding to the plurality of light-emitting structures 31. The light reflecting portion Z2 is located in the second electrode layer 50 and arranged with the second electrode 51.

[0170] The second electrode 51 is used to drive the light-emitting structure 31 to emit light together with the first electrode 41. On this basis, the embodiment of the present application sets the light reflecting part Z2 and the second electrode 51 in the same layer, so as to reduce the influence of the light reflecting part Z2 on the overall thickness of the display panel, which helps to achieve a lightweight design of the display panel.
