[0047] The following describes in detail the features and exemplary embodiments of each aspect of the present application, and in order to more clearly understand the objectives, technical solutions, and advantages of the present application, the present application will be described in more detail below with reference to the drawings and specific examples. It should be understood that the specific examples described herein are intended only to interpret the present application and do not limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the examples is provided merely to illustrate the present application and to provide a better understanding of the present application.

[0048] It should be noted that, in this specification, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another and do not necessarily require or imply that such an actual relationship or order exists between those entities or operations. Furthermore, the terms "comprises," "having," or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or device that includes a set of elements not only includes those elements, but also other elements not expressly listed or that are inherent in such process, method, article, or device. Absent more limitations, elements qualified by the phrase "comprises" do not exclude the presence of other identical elements in a process, method, article, or device that includes the elements.

[0049] With the development of information technology, the demand for smarter, lighter and faster display devices is increasing, and in order to meet the diversified demand for display devices, for example, display devices of mobile phones, computers, etc., not only need to meet the display demand, but also need to meet the touch demand for these display devices. In view of this, how to realize the integration of touch functions in display devices has become the research direction of many manufacturers.

[0050] 1 and 2, an 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-controlling part 60, wherein the isolation structure 20 includes a plurality of isolation units D1 disposed at one side of the substrate 10 and spaced apart from each other, and the isolation units D1 surround and form at least one aperture structure 21. The light-emitting functional layer 30 includes a light-emitting structure 31 disposed at one side of the substrate 10 and corresponding to the aperture structure 21.

[0051] The first electrode layer 40 is provided on the side of the light-emitting functional layer 30 away from the substrate 10, and includes a first electrode 41 provided corresponding to the aperture structure 21. The light-adjusting portion 60 is provided on one side of the substrate 10, and at least a portion of the orthogonal projection of the light-adjusting portion 60 on the substrate 10 is located between the orthogonal projections of the adjacent isolation units D1 on the substrate 10.

[0052] The substrate 10 mainly serves as a support or bearing, and other film layers are sequentially stacked on the substrate 10. The term "stacked" as used herein refers to other film layers sequentially stacked along the thickness direction X of the substrate 10, and the substrate 10 may include a plurality of film layer structures. The specific composition of the film layer structure is not limited by the embodiments of the present application. Furthermore, the thickness direction X of other film layers located on one side of the substrate 10 typically coincides with the thickness direction X of the substrate 10 itself, and therefore, for convenience of explanation, the thickness direction X of the substrate 10 or the thickness direction X of other film layers described later in the embodiments of the present application will be shown as the same direction.

[0053] The light-emitting functional layer 30 is located on the same side of the substrate 10 as the isolation structure 20, and includes a light-emitting structure 31 provided corresponding to the opening structure 21. The phrase "the light-emitting structure 31 is provided corresponding to the opening structure 21" used herein means that at least a portion of the orthogonal projection of the light-emitting structure 31 on the substrate 10 is located within the orthogonal projection of the opening structure 21 on the substrate 10. The light-emitting structure 31 may be located within the opening structure 21 or on the side of the opening structure 21 facing the substrate 10, and the embodiments of the present application are not limited thereto.

[0054] The light-emitting structures 31 include, but are not limited to, a red light-emitting structure 31 that emits red light, a green light-emitting structure 31 that emits green light, and a blue light-emitting structure 31 that emits blue light. Each light-emitting structure 31 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting layer, an electron injection layer (EIL), and an electron transport layer (ETL), which are stacked one on the other.

[0055] The first electrode layer 40 is located on the side of the light-emitting functional layer 30 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 corresponding to the aperture structures 21. That is, at least a portion of the orthogonal projection of the first electrode 41 on the substrate 10 is located within the orthogonal projection of the aperture structures 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. The second electrode layer 50 is provided with a plurality of second electrodes 51, and the plurality of second electrodes 51 are provided corresponding to the plurality of light-emitting structures 31. The first electrode 41 and the second electrode 51 jointly drive the light emission of the light-emitting structures 31. Exemplarily, the first electrode 41 is a cathode, and the second electrode 51 is an anode.

[0056] The isolation structure 20 includes a plurality of isolation units D1 spaced apart, with a certain interval between each isolation unit D1 to achieve mutual insulation between the different isolation units D1. The isolation units D1 may surround at least one aperture structure 21, and the light emitting structures 31 and the first electrodes 41 may be disposed corresponding to the aperture structure 21. The provision of the isolation structure 20 allows the light emitting functional layer 30 to form a plurality of spaced apart light emitting structures 31 without the need for a fine metal mask plate.

[0057] Specifically, for example, if the red light-emitting structure 31 is manufactured before the green light-emitting structure 31, the fine metal mask plate is eliminated, so that the red light-emitting material corresponding to the red light-emitting structure 31 first enters each opening structure 21, and then the red light-emitting material in some of the opening structures 21 is selectively etched away, leaving the red light-emitting material in some of the opening structures 21 to form the red light-emitting structure 31. Then, the green light-emitting material corresponding to the green light-emitting structure 31 falls into each opening structure 21, and then the green light-emitting material in some of the opening structures 21 is selectively etched away, leaving the green light-emitting material in some of the opening structures 21 to form the green light-emitting structure 31.

[0058] Similarly, due to the presence of the isolation structure 20, the first electrode layer 40 may include a plurality of first electrodes 41 provided corresponding to the aperture structures 21. That is, the plurality of first electrodes 41 can be provided corresponding to the plurality of light emitting structures 31 so as to realize drive control for the light emitting structures 31. For a plurality of aperture structures 21 formed surrounded by the same isolation unit D1, the plurality of first electrodes 41 provided corresponding to the plurality of aperture structures 21 are provided in electrical connection to the isolation unit D1.

[0059] Based on this, in some embodiments, a conductive material may be provided in the isolation unit D1, and a first electrode 41 may be provided in contact with and electrically connected to a corresponding isolation unit D1. Thus, the isolation unit D1 and one or more first electrodes 41 corresponding to the isolation unit D1 can jointly form a touch unit D2. For example, a plurality of first electrodes 41 electrically connected to the same isolation unit D1 and the isolation unit D1 form a touch unit D2. In other words, the first electrode 41, in addition to fulfilling the driving control for the light-emitting structure 31, also serves to form the touch unit D2 for realizing the touch function.

[0060] Specifically, the isolation unit D1 may be provided in contact with and electrically connected to the first electrode 41, so that during use of the display panel, a control module such as a driver chip IC can transmit a power signal to the isolation unit D1 within a certain time period. The isolation unit D1 transmits a corresponding power signal to the first electrode 41 to fulfill the light-emitting driving function of the light-emitting structure 31 of the first electrode 41. In other time periods, the driver chip IC can transmit a specific touch signal to the touch unit D2 consisting of the first electrode 41 and the isolation unit D1 so that the display panel can achieve the touch function. That is, in different time periods, 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 simultaneously achieve the display function and the touch function and can control the display function and the touch function according to time and region.

[0061] In some embodiments, one isolation unit D1 and at least one first electrode electrically connected to the isolation unit D1 form one touch unit D2, and adjacent touch units D2 are spaced apart.

[0062] In this embodiment, the touch function realized by the plurality of touch units D2 may be a self-capacitance touch function.

[0063] In the above embodiment, the isolation unit D1 and the first electrode 41 may be combined into a touch unit for other purposes, and in another embodiment, a plurality of isolation units D1 spaced apart may be used to achieve 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 regions have different voltages, thereby achieving independent control of the first electrode 41 segments.

[0064] In the embodiment of the present application, the isolation structure 20 is patterned and arranged so that the isolation structure 20 can define a plurality of isolation units D1 with insulating intervals, and the isolation units D1 and the corresponding first electrodes 41 can jointly form touch units D2, and different types of signals can be transmitted to the first electrodes 41 in different time periods, so that the display panel can control the display and touch functions by time and area without requiring an additional touch layer, which contributes to reducing the overall thickness of the display panel and contributing to a thinner design of the display panel.

[0065] However, since there is a certain gap between each isolating unit D1, the display panel has regions where the isolating units D1 are present and regions where the isolating units D1 are not present, and these two regions generally contain light-reflecting material, but the distribution patterns of the light-reflecting material are different to some extent, which makes it easy for the light reflectance and other factors to differ in different regions of the display panel, and therefore increases the risk of the pattern of the isolating structure 20 being visible when the screen of the display panel is turned off.

[0066] In view of this, the embodiment of the present application further adds a light-adjusting unit 60, which is mainly used to compensate for or adjust or absorb / shield ambient light. The orthogonal projection of the light-adjusting unit 60 on the substrate 10 is positioned between the orthogonal projection of the adjacent isolation unit D1 on the substrate 10, so that the light-adjusting unit 60 can adjust the light incident between the adjacent touch units D2. For example, the light-adjusting unit 60 absorbs / shields or reflects the incident light, and whether the light-adjusting unit 60 absorbs / shields or reflects the incident light is determined based on whether the isolation unit D1 has the ability to absorb or reflect the incident light. This can reduce the difference in light between the area of ​​the display panel where the isolation unit D1 is provided and the area where the isolation unit D1 is not provided, and improve the usability of the display panel.

[0067] The light-adjusting unit 60 may have a variety of forms, and may achieve a light-blocking effect by absorbing at least a portion of light, or may adjust the light reflectance at a corresponding position on the display panel using a material such as metal to reduce the difference in light reflectance at different positions, thereby achieving a compensatory adjustment of light.

[0068] In addition, the light-adjusting portion 60 may have multiple positional forms, for example, at least a portion of the light-adjusting portion 60 may be located on the side of the isolation structure 20 away from the substrate 10, or at least a portion of the light-adjusting portion 60 may be located in the same film layer as the isolation structure 20, or at least a portion of the light-adjusting portion 60 may be located on the side of the isolation structure 20 facing the substrate 10, and the embodiments of the present application are not limited thereto.

[0069] In some embodiments, both the isolation unit D1 and the light-modulating part 60 include a light-blocking material, or both the isolation unit D1 and the light-modulating part 60 include a light-reflecting material, so that the gap between each adjacent isolation unit D1 has light-blocking or light-reflecting properties, thereby reducing the difference between the area of ​​the display panel where the isolation unit D1 is provided and the area where the isolation unit D1 is not provided, and reducing the risk of the pattern of the isolation structure 20 being visible when the screen of the display panel is turned off.

[0070] In some embodiments, as shown in Figures 1 and 2, the isolation structure 20 includes a first isolation portion 22 and a second isolation portion 23 stacked in sequence along a direction away from the substrate 10, and the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the second isolation portion 23 on the substrate 10.

[0071] The specific size and shape of the first isolation portion 22 and the second isolation portion 23 are not limited to those of the embodiments of the present application. For example, the cross section of the isolation structure 20 may be U-shaped, T-shaped, or inverted trapezoidal. This design contributes to cutting the light-emitting material and the electrode material at the edge of the isolation structure 20 during the manufacturing process of the light-emitting functional layer 30 and the first electrode layer 40, thereby realizing the manufacture and separation of the light-emitting structures 31 and the first electrodes 41 corresponding to the different opening structures 21 without the need for a fine metal mask plate.

[0072] The present embodiment does not limit the material composition of the first isolation portion 22 and the second isolation portion 23, and both the first isolation portion 22 and the second isolation portion 23 may include a conductive material, or the first isolation portion 22 may include a conductive material and the second isolation portion 23 may include an insulating material, as long as the first electrode 41 can achieve signal transmission through at least one of the first isolation portion 22 and the second isolation portion 23.

[0073] In some embodiments, the first isolation portion 22 includes a conductive material, and the first electrode 41 is provided in electrical connection with the first isolation portion 22 .

[0074] The first electrode 41 is electrically connected to the first isolation portion 22, and 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 via another conductive structure, and the embodiments of the present application are not limited thereto.

[0075] In the embodiment of the present application, by providing a conductive material in the first isolation portion 22, the display panel can realize the transmission of power signals to the first electrode 41 through the first isolation portion 22, thereby meeting the need for signal transmission and being advantageous for driving the touch and display of the display panel in different time and regions.

[0076] In some embodiments, as shown in Figures 1 and 3, the isolation structure 20 further includes a third isolation portion 24 located on the side of the first isolation portion 22 facing the substrate 10, and the third isolation portion 24 includes a conductive material and is electrically connected to the first isolation portion 22.

[0077] 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, and 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. Illustratively, the orthogonal projection of the first isolation portion 22 on the substrate 10 is located within the orthogonal projection of the third isolation portion 24 on the substrate 10, i.e., the vertical cross-sectional shapes of the first isolation portion 22, the second isolation portion 23, and the third isolation portion 24 are U-shaped.

[0078] Like the first isolation portion 22, the third isolation portion 24 also includes a conductive material, and the first electrode 41 may be in direct contact with the third isolation portion 24 so as to establish electrical connection with the first isolation portion 22 via the third isolation portion 24. Optionally, the first electrode 41 is provided so as to overlap and connect to the third isolation portion 24. Furthermore, a portion of the first electrode 41 may be located on the side of the third isolation portion 24 that is away from the substrate 10, and the provision of the third isolation portion 24 contributes to improving the reliability of the electrical connection between the first electrode 41 and the isolation structure 20.

[0079] In some embodiments, as shown in FIGS. 1 and 2, the display panel further includes a plurality of connecting lines Z1, and at least some different connecting lines Z1 are electrically connected to different isolation units D1.

[0080] The connecting line Z1 is electrically connected to the isolation unit D1 and transmits a touch signal to the touch unit D2 during a specific time period or a power signal to the first electrode 41 in the touch unit D2 during a specific time period, thereby achieving time- and region-specific driving of the display panel for display and touch. The connecting line Z1 may be in contact with the first isolation portion 22 in the isolation unit D1. Alternatively, the connecting line Z1 may be in contact with the second isolation portion 23 in the isolation unit D1. Alternatively, the connecting line Z1 may be in contact with the third isolation portion 24 in the isolation unit D1. That is, the connecting line Z1 only needs to be in contact with a structure for electrically connecting with the first electrode 41 in the touch unit D2. For example, the connecting line Z1 may be in contact with the isolation structure 20. In some alternative embodiments, the connecting line Z1 is in contact with the first isolation portion 22. Alternatively, in other alternative embodiments, the connecting line Z1 is in contact with the first isolation portion 23.

[0081] In the 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 through the different connecting lines Z1, thereby realizing the division control of the display function and the touch function and improving the display or touch accuracy of the display panel.

[0082] In addition, the number of connecting lines Z1 corresponding to one isolation unit D1 may be one or more, and the number of connecting lines Z1 corresponding to different isolation units D1 may be the same or different, and the embodiments of the present application are not limited thereto.

[0083] Furthermore, the layout design of the connecting lines Z1 in the display panel is not limited by the embodiments of the present application. In some optional embodiments, as shown in Figures 4 and 5, the light adjusting unit 60 includes at least some of the connecting lines Z1, and the orthogonal projection of the connecting lines Z1 on the substrate 10 is located between the adjacent isolation units D1.

[0084] The orthogonal projections of at least some of the connecting lines Z1 on the substrate 10 are located between the orthogonal projections of the adjacent isolation units D1 on the substrate 10, so that at least some of the connecting lines Z1 can be used as light adjusting units 60. Specifically, the connecting lines Z1 may include metal materials such as copper, aluminum, and titanium, and the orthogonal projections of at least some of the connecting lines Z1 on the substrate 10 are located between the orthogonal projections of the adjacent isolation units D1 on the substrate 10, so that the light reflectance of the areas corresponding to the adjacent touch units D2 on the display panel can be adjusted through the connecting lines Z1, thereby reducing the difference in light reflectance corresponding to different areas and contributing to reducing the risk of the isolation units D1 being visible when the screen of the display panel is turned off.

[0085] Furthermore, the embodiment of the present application can achieve a light adjustment effect on the area between adjacent isolation units D1 of the display panel through the connecting lines Z1. In this way, no additional metal material is required, and the display uniformity is improved, contributing to reducing the manufacturing cost of the display panel. At the same time, at least some of the connecting lines Z1 are arranged to avoid the light-emitting structures 31, thereby improving the display effect of the display panel.

[0086] The specific location of the connecting line Z1 between adjacent isolation units D1 whose orthogonal projections are located is not limited in the embodiments of the present application. For example, the connecting line Z1 between adjacent isolation units D1 whose orthogonal projections are located may be provided on the side of the isolation structure 20 away from the substrate 10, or on the side of the light-emitting functional layer 30 facing the substrate 10.

[0087] In some embodiments, the orthogonal projections of at least some of the connecting lines Z1 on the substrate 10 are arranged to overlap with the orthogonal projections of the isolation unit D1 on the substrate 10, i.e., at least some of the connecting lines Z1 are arranged on the side of the isolation unit D1 away from the substrate 10.

[0088] In the embodiment of the present application, some of the connecting lines Z1 are arranged corresponding to the isolation units D1, so that the connecting lines Z1 can extend along the isolation units D1. In this way, the orthogonal projections of the connecting lines Z1 on the substrate 10 and the orthogonal projections of the light emitting structures 31 on the substrate 10 can be offset from each other, thereby reducing the influence of the connecting lines Z1 on the light emitted by the light emitting structures 31 and improving the display effect of the display panel.

[0089] In some embodiments, as shown in FIG. 6, the display panel further includes a virtual wire Z3 arranged parallel to and insulated from the connecting wire Z1, and the spacing between any two adjacent wires in the parallel-arranged multiple connecting wires Z1 and virtual wires Z3 is the same.

[0090] The virtual wire Z3 may include the same material as the connecting wire Z1, but differs from the connecting wire Z1 in that the virtual wire Z3 is not electrically connected to the isolation unit D1, so that the virtual wire Z3 and the connecting wire Z2 are insulated from each other. Furthermore, the virtual wire Z3 may not be electrically connected to any other signal, i.e., no signal is transmitted within the virtual wire Z3.

[0091] The virtual wire Z3 may be positioned by being inserted between the multiple connection wires Z1, and the extension direction of the virtual wire Z3 may coincide with the extension direction of the connection wire Z1, so that the two may be arranged in parallel. Based on this, in the multiple connection wires Z1 and virtual wire Z3 arranged in parallel, the spacing between any two adjacent wires coincides. The "any two adjacent wires" referred to here may be two connection wires Z1, or one connection wire Z1 and one virtual wire Z3, or two virtual wires Z3, as long as there are no other connection wires or virtual wires Z3 between the two wires.

[0092] In the embodiment of the present application, a virtual wiring Z3 is added within the display panel, and the spacing between any two adjacent wirings among the multiple connecting lines Z1 and virtual wiring Z3 arranged in parallel is made consistent, thereby making the arrangement density of the conductive material constituting the connecting lines Z1 and virtual wiring Z3 consistent in different regions of the display panel, thereby reducing the difference in light reflectivity corresponding to different regions and contributing to reducing the risk of the isolation unit D1 being visible when the display panel screen is off.

[0093] 6, the orthogonal projections of the connecting lines Z1 and the virtual wiring Z3 on the substrate may overlap with the light-emitting structure, and based on this, in order to reduce the influence of the connecting lines Z1 and the virtual wiring Z3 on the light-emitting effect, the connecting lines Z1 and the virtual wiring Z3 may be provided on the side of the light-emitting structure facing the substrate. In addition, the positions of the connecting lines Z1 and the virtual wiring Z3 may be adjusted so that the orthogonal projections of the connecting lines Z1 and the virtual wiring Z3 on the substrate do not overlap with the light-emitting structure.

[0094] The embodiments of the present application do not limit the type of signal transmitted within the connecting line Z1. Optionally, the connecting line Z1 includes a power signal line for supplying a power signal to the first electrode 41 to control whether the light-emitting structure 31 emits light. Alternatively, in some embodiments, the first electrode 41 is electrically connected to the isolation unit D1 to form a touch unit D2, and the connecting line Z1 includes a touch signal line. The touch signal line provides a touch signal to the touch unit D2 to realize the touch function of the display panel.

[0095] The isolation unit D1 includes a transparent material and / or a light-reflecting material. The material compositions of the first isolation portion 22 and the second isolation portion 23 are not limited to the embodiments of the present application. Optionally, the first isolation portion 22 includes a transparent or light-reflecting material, and / or the second isolation portion 23 includes a transparent or light-reflecting material. In some specific embodiments, the first isolation portion 22 includes a light-reflecting material, and the second isolation portion 23 includes a light-transmitting material, for example, aluminum, and a light-transmitting metal oxide, or both the first isolation portion 22 and the second isolation portion 23 include a light-reflecting material, for example, aluminum, and a titanium, for example.

[0096] In some embodiments, as shown in Figures 1 and 2, the light adjusting portion 60 includes a light blocking portion 61, and the orthogonal projection of at least some of the structures in the light blocking portion 61 on the substrate 10 is located between the orthogonal projections on the substrate 10 of the adjacent isolation unit D1.

[0097] 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 to the embodiments of the present application. For example, the light-shielding portion 61 includes an organic material. Preferably, the light-shielding portion 61 includes a light-shielding material.

[0098] In the embodiment of the present application, the orthogonal projection on the substrate 10 of at least a part of the structure of the light-shielding portion 61 is positioned between the orthogonal projections on the substrate 10 of the adjacent isolation units D1, thereby realizing absorption of light rays incident on the display panel through the light-shielding portion 61 between the corresponding adjacent isolation units D1, which also contributes to improving the uniformity of the display panel.

[0099] The specific location of the light blocking portion 61 on the display panel is not limited by the embodiments of the present application. Alternatively, at least a portion of the light blocking portion 61 may be located in the same film layer as the isolation structure 20, for example, at least a portion of the light blocking portion 61 may be located in the same film layer as the first isolation portion 22, i.e., at least a portion of the light blocking portion 61 may be filled between the first isolation portions 22 corresponding to adjacent isolation units D1. This allows the light blocking portion 61 to fill the gap space formed by the adjacent isolation units D1, which is advantageous for the fabrication of subsequent film layers.

[0100] In some embodiments, the display panel further includes a plurality of connecting lines Z1, at least some of the different connecting lines Z1 being electrically connected to different isolation units D1, and at least some of the connecting lines Z1 being located on the side of the light-shielding portion 61 facing the substrate 10.

[0101] In the embodiment of the present application, at least some of the connecting lines Z1 are located on the side of the light-shielding portion 61 facing the substrate 10, and in this case, at least some of the connecting lines Z1 are made of the same material in the same layer as the conductive material in the display panel, thereby improving the manufacturing efficiency of the display panel.

[0102] Alternatively, in another embodiment, at least a portion of the light-shielding portion 61 is located on the side of the isolation structure 20 away from the substrate 10, i.e., at least a portion of the light-shielding portion 61 is located on the side of the second isolation portion 23 away from the substrate 10.

[0103] In the embodiment of the present application, at least a portion of the light blocking portion 61 is disposed on the side of the second isolation portion 23 that faces away from the substrate 10, so that the light blocking portion 61 can cover at least a portion of the structure of the second isolation portion 23. Therefore, during the manufacturing process of the light blocking portion 61, the size of the light blocking portion 61 needs to be disposed so that it exceeds the side of the second isolation portion 23 that faces away from the substrate 10, so that the light blocking portion 61 can be more effectively filled between the adjacent isolation units D1 and the light blocking effect of the light blocking portion 61 on the area between the adjacent touch units D2 can be further improved.

[0104] If the second isolation portion 23 includes a black material, the light adjusting portion 60 may include a light blocking portion 61, that is, the light blocking portion 61 may be located between the orthogonal projections of the adjacent isolation units D1 on the substrate 10. The light blocking portion 61 absorbs at least a portion of the ambient light, thereby reducing the risk of the isolation units D1 being visible when the display panel screen is off.

[0105] In some alternative embodiments, at least a portion of the light-shielding portion 61 is located on the side of the isolation structure 20 away from the substrate 10, and the orthogonal projection of the light-shielding portion 61 on the substrate 10 is configured to overlap with the orthogonal projection of the isolation structure 20 on the substrate 10. With this design, the light-shielding portion 61 can be simultaneously located at the position of the isolation structure 20 and in the gap between the adjacent isolation units D1, thereby further reducing the difference in different regions and reducing the risk of the isolation units D1 being visible when the screen of the display panel is off.

[0106] Alternatively, the orthogonal projection of the light-shielding portion 61 on the substrate 10 covers the orthogonal projection of the isolation structure 20 on the substrate 10. For example, if the isolation structure 20 does not have a light-shielding function, the orthogonal projection of the light-shielding portion 61 on the substrate 10 covers the orthogonal projection of the isolation structure 20 on the substrate 10, i.e., the upper surface of the isolation structure 20 is covered by the light-shielding portion 61, so that the effect on light of the area with the isolation structure 20 and the area without the isolation structure 20 is the same.

[0107] Alternatively, if the isolation structure 20 has a light-shielding function, the light-shielding portion 61 may be provided in the gap between the adjacent isolation units D1, and the upper surface of the isolation structure 20 may not cover the light-shielding portion 61.

[0108] Optionally, when the second isolation portion 23 or the first isolation portion 22 includes a light-reflective material, the light adjusting portion 60 may include at least some connecting lines Z1 or other structures capable of reflecting light, i.e., at least some connecting lines Z1 may be located between the orthogonal projections of adjacent isolation units D1 on the substrate 10. The connecting lines Z1 can adjust the light reflectance of the areas corresponding to the adjacent isolation units D1 on the display panel, thereby reducing the difference in light reflectance corresponding to different areas and contributing to reducing the risk of the isolation units D1 being visible when the screen of the display panel is off.

[0109] In some embodiments, as shown in FIG. 7, at least some of the connection lines Z1 are located on the side of the light blocking portion 61 that is away from the substrate 10.

[0110] In the present embodiment, at least some of the connecting lines Z1 can be arranged to be located on the side of the light-shielding portion 61 that faces away from the substrate 10, and thus the connecting lines Z1 can be formed after the isolation structure 20 and the light-shielding portion 61 are manufactured. Compared to a design in which the connecting lines Z1 are located on the side of the isolation structure 20 that faces the substrate 10, the connecting lines Z1 in this design do not occupy space on the side of the isolation structure 20 that faces the substrate 10, i.e., the connecting lines Z1 are not arranged in the same layer as other wiring structures on the side of the isolation structure 20 that faces the substrate 10, thereby reducing the risk of the distance between adjacent wiring being too small, reducing the wiring density, and improving the reliability of wiring signal transmission within the display panel.

[0111] In addition, the connecting line Z1 needs to contact some structures in the isolation unit D1 to meet the needs of signal transmission, and based on this, the connecting line Z1 may contact the isolation unit D1 in multiple ways, and the embodiments of the present application are not limited thereto. In some optional embodiments, first via holes are provided in the light-shielding portion 61, and at least some of the connecting lines Z1 are connected to the isolation unit D1 through the first via holes.

[0112] The presence of the first via hole can meet the contact demand between the connecting line Z1 and the isolation unit D1. The first via hole is arranged to penetrate the light-shielding portion 61 along the thickness direction X. The first via hole enables the connecting line Z1 to realize contact with the isolation unit D1, thereby meeting the signal transmission demand to the isolation unit D1 and the first electrode 41, and realizing the time- and area-specific driving of the display and touch functions of the display panel.

[0113] Furthermore, in some embodiments, the second isolation portion 23 is provided with a second via hole that is electrically connected to the first via hole, and at least some of the connecting lines Z1 are electrically connected to the first isolation portion 22 via the first via hole and the second via hole.

[0114] As can be seen from the above, the first isolation portion 22 may include a conductive material, and the second isolation portion 23 may include an insulating material, and based on this, in order to meet the demand for signal transmission, the connecting line Z1 needs to be arranged in contact with the first isolation portion 22. In view of this, in the embodiment of the present application, a second via hole is added to the isolation unit D1, and the connecting line Z1 can achieve contact connection with the first isolation portion 22 through the first via hole and the second via hole, thereby meeting the demand for signal transmission to the isolation unit D1 and the first electrode 41, and realizing the time- and area-specific driving of the display and touch functions of the display panel.

[0115] In some embodiments, as shown in FIG. 8, the display panel further includes a protective layer 90 located on the side of the connecting line Z1 that faces away from the substrate 10.

[0116] The protective layer 90 is disposed to cover the connecting line Z1, and the presence of the protective layer 90 can provide a certain shielding effect, thereby reducing the influence of other film layers inside the display panel on the connecting line Z1 and improving the reliability of signal transmission inside the connecting line Z1. The protective layer 90 may have multiple forms, for example, the protective layer 90 may include multiple protective portions disposed at intervals, and the multiple protective portions are disposed corresponding to the multiple connecting lines Z1 so as to individually protect different connecting lines Z1.

[0117] Alternatively, in some alternative embodiments, the protective layer 90 is provided to cover the connecting line Z1 and the light-shielding portion 61 at the same time.

[0118] In the embodiment of the present application, the protective layer 90 may have a full-surface structure, or may be arranged to cover the connecting line Z1 and the light-shielding portion 61 at the same time, thereby contributing to the protective layer 90 better realizing the covering effect on the connecting line Z1, and by providing the protective layer 90 in different areas of the display panel, the impact of the presence of the protective layer 90 on the display uniformity can be reduced, and the display uniformity of the display panel can be improved.

[0119] Similarly, the present embodiment does not limit the thickness of the protective layer 90. Preferably, the thickness of the protective layer 90 is W, where W satisfies 3 nm≦W≦300 nm. This design satisfies the protection needs of the protective layer 90 and minimizes the impact of the protective layer 90 on the overall thickness of the display panel, contributing to a thinner design of the display panel.

[0120] In some embodiments, as shown in Figures 1 and 2, the display panel further includes a first sealing layer 71 located on the side of the first electrode layer 40 away from the substrate 10, the first sealing layer 71 including a first sealing portion 711 provided corresponding to the opening structure 21, and the protective layer 90 covering at least a portion of the first sealing portion 711.

[0121] The first encapsulating layer 71 is located on the side of the first electrode layer 40 away from the substrate 10, i.e., on the light-emitting surface side of the light-emitting structure 31. The first encapsulating layer 71 can provide encapsulation protection for the light-emitting structure 31. Due to the presence of the isolation structure 20, the manufactured first encapsulating layer 71 can have multiple first encapsulating portions 711 corresponding to the light-emitting structures 31 and located within the opening structure 21, and each first encapsulating portion 711 can provide an independent encapsulation for each light-emitting structure 31, thereby improving the encapsulation protection effect for the light-emitting structures 31.

[0122] Furthermore, the protective layer 90 also covers at least a portion of the first encapsulating portion 711, and the presence of the protective layer 90 can further improve the encapsulation and protection effect for the light emitting structure 31. The material compositions of the first encapsulating layer 71 and the protective layer 90 are not limited in the embodiments of the present application. Illustratively, the first encapsulating layer 71 includes an inorganic material.

[0123] In some embodiments, the display panel further includes a second encapsulation layer 72 located on the side of the protective layer 90 away from the substrate 10 .

[0124] The first encapsulating layer 71 and the second encapsulating layer 72 are both used to provide encapsulation protection. Optionally, the display panel further includes a third encapsulating layer 73 located on the side of the second encapsulating layer 72 away from the substrate 10. The first encapsulating layer 71, the second encapsulating layer 72, and the third encapsulating layer 73 together form a thin-film encapsulation structure. This further reduces the risk of water, oxygen, and the like penetrating into the light-emitting structure 31, improving the reliability of the display panel. The material compositions of the second encapsulating layer 72 and the third encapsulating layer 73 are not limited by the present embodiment. Optionally, the first encapsulating layer 71 and the third encapsulating layer 73 are both made of an inorganic material, and the second encapsulating layer 72 is made of an organic material. In this way, the first encapsulating layer 71 and the second encapsulating layer 72 can serve to some extent as a positioning constraint for the second encapsulating layer 72, improving the reliability of the structure.

[0125] Apart from the difference in materials, the second encapsulating layer 72 differs from the first encapsulating layer 71 in that the second encapsulating layer 72 has a continuous structure covering the entire surface. Based on this, in the present embodiment, a protective layer 90 is provided between the first encapsulating layer 71 and the second encapsulating layer 72. The protective layer 90 may have a full-surface structure, which can help the first encapsulating layer 71 to restrict the position of the second encapsulating layer 72 and improve the reliability of the encapsulation structure. Optionally, the protective layer 90 includes an inorganic material, such as silicon nitride, silicon oxide, or silicon oxynitride, and the second encapsulating layer 72 includes an organic material.

[0126] In some embodiments, as shown in FIG. 9, the display panel further includes a driver chip IC, and the connecting lines Z1 are connected to the driver chip IC, and in the direction M away from the driver chip IC, the number of connecting lines Z1 connected to corresponding isolation units D1 tends to gradually increase.

[0127] The driving chip IC can transmit a corresponding touch signal to the isolation unit D1 through the connecting line Z1, and transmit a corresponding power signal to the first electrode 41 through the connecting line Z1 and the isolation unit D1, so as to meet the time and area-wise driving of the display and touch functions of the display panel.

[0128] Furthermore, the distances between at least some different isolation units D1 and the driving chip IC are different, and therefore the lengths of the connecting lines Z1 corresponding to at least some different isolation units D1 are different, and therefore the resistance values ​​corresponding to the different connecting lines Z1 are different. Therefore, if the number of connecting lines Z1 corresponding to different touch units D2 is set to be the same, the resistance values ​​of the connecting lines Z1 connected to different touch units D2 will be different, and the signal strengths received by different touch units D2 will be different, which is likely to cause display unevenness or touch failure.

[0129] In view of this, the embodiments of the present application adjust the number of connecting lines Z1 corresponding to at least some different isolation units D1, so that the number of connecting lines Z1 connected to corresponding touch units D2 gradually increases in the direction M away from the driving chip IC, that is, the farther away from the driving chip IC, the more connecting lines Z1 are connected to the same isolation unit D1, thereby reducing the difference in resistance value of connecting lines Z1 corresponding to different touch units D2, reducing the difference in signal strength received by different touch units D2, and improving the reliability of display and touch.

[0130] In some alternative embodiments, the resistance value of the connecting line Z1 corresponding to some of the isolation units D1 is R1, and the resistance value of the connecting line Z1 corresponding to some of the isolation units D1 is R2, where R1 and R2 satisfy -0.1≦(R1−R2) / R1≦0.1.

[0131] The "connecting line Z1 corresponding to the isolation unit D1" referred to in the embodiments of the present application refers to the connecting line Z1 electrically connected to the isolation unit D1. When the isolation unit D1 is electrically connected to only one connecting line Z1, the resistance value of the connecting line Z1 corresponding to the isolation unit D1 is the resistance value of the single connecting line Z1. When the isolation unit D1 is electrically connected to multiple connecting lines Z1 at the same time, the resistance value of the connecting line Z1 corresponding to the isolation unit D1 is the resistance value of the multiple connecting lines Z1 configured in parallel.

[0132] In the embodiment of the present application, the parameters such as the number of connecting lines corresponding to different isolation units D1 are adjusted so that the difference in resistance value of the connecting lines Z1 corresponding to different isolation units D1 is not more than 10%, thereby reducing the difference in signal strength received by different isolation units D1 and improving the reliability of display and touch.

[0133] 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, where n is a positive integer greater than 1, and a and b satisfy a:b=n:1.

[0134] Typically, the resistance value of a single connecting line Z1 is directly proportional to its length, whereas when multiple connecting lines Z1 of the same length are connected in parallel, the corresponding total resistance value is inversely proportional to the number of connecting lines Z1. Specifically, if the length of a single connecting line Z1 corresponding to an isolation unit D1 located in the first row is L, the length of a single connecting line Z1 corresponding to an isolation unit D1 located in the nth row is nL, and the resistance value of a single connecting line Z1 corresponding to an isolation unit D1 located in the nth row is n times the resistance value of a single connecting line Z1 corresponding to an isolation unit D1 located in the first row.

[0135] Based on this, the embodiment of the present application sets the number of connecting lines Z1 corresponding to the isolation units D1 located in the nth row to be n times the number of connecting lines Z1 corresponding to the isolation units D1 located in the first row, so that, under other conditions, the resistance values ​​of the multiple connecting lines Z1 arranged in parallel corresponding to the touch electrodes in the nth row can be made the same as or close to the resistance value of the connecting lines Z1 corresponding to the touch electrodes in the first row, thereby further reducing the difference in resistance values ​​of the connecting lines Z1 corresponding to different isolation units D1, reducing the difference in signal strength received by different isolation units D1, and improving the reliability of display and touch.

[0136] In some embodiments, referring to Figures 10 and 11, the display panel further includes a pixel definition layer 80 located on the side of the isolation structure 20 facing the substrate 10, and the pixel definition layer 80 includes a pixel limiting portion 81 and a pixel opening 82 formed by and surrounded by the pixel limiting portion 81.

[0137] The pixel definition layer 80 includes a pixel limiting portion 81 and a pixel opening 82, and the pixel opening 82 is disposed corresponding to the aperture structure 21. For example, the orthogonal projection of the pixel opening 82 on the substrate 10 may be located within the orthogonal projection of the aperture structure 21 on the substrate 10, and some structures of the light-emitting structure 31 and the first electrode 41 may be located within the pixel opening 82. In some embodiments, the light adjusting portion 60 includes a light reflecting portion Z2 located on the side of the pixel limiting portion 81 facing the substrate 10, and at least a portion of the orthogonal projection of the light reflecting portion Z2 on the substrate 10 is located between the orthogonal projections of the adjacent touch units D2 on the substrate 10.

[0138] The light-reflecting portion Z2 is used to reflect ambient light. Optionally, the light-reflecting portion Z2 may include a conductive material, be located on the side of the pixel definition layer 80 facing the substrate 10, and may or may not be electrically connected to other conductive structures. That is, during use of the display panel, the interior of the light-reflecting portion Z2 may or may not be used to transmit a specific signal, and the embodiment of the present application is not limited thereto.

[0139] Furthermore, at least a portion of the orthogonal projection of the light reflecting portion Z2 on the substrate 10 is located between the orthogonal projections of the adjacent isolation units D1 on the substrate 10, thereby adjusting the light reflectance of the corresponding area between the adjacent isolation units D1 on the display panel through the light reflecting portion Z2. This reduces the difference in light reflectance corresponding to different areas and contributes to reducing the risk of the isolation units D1 being visible when the display panel screen is turned off. The embodiment of the present application does not limit the material composition of the light reflecting portion Z2. Optionally, the light reflecting portion Z2 may include a metal material such as copper, aluminum, or titanium.

[0140] In addition, when the isolation unit D1 is provided with a light-reflecting structure, the embodiment of the present application is adapted to adjust the reflective uniformity of the light in the area between the isolation unit D1 and the adjacent isolation unit D1 through the light-reflecting portion Z2, thereby reducing the risk of the touch unit D2 being visible when the display panel screen is off. Optionally, the first isolation portion 22 includes a transparent or light-reflective material, and / or the second isolation portion 23 includes a transparent or light-reflective material. In some specific embodiments, the first isolation portion 22 includes a light-reflective material, and the second isolation portion 23 includes a light-transmitting material, for example, aluminum and titanium, or both the first isolation portion 22 and the second isolation portion 23 include a light-reflective material, for example, aluminum and titanium, respectively.

[0141] 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 provided corresponding to the plurality of light-emitting structures 31. The light-reflecting portion Z2 is located in the second electrode layer 50 and is provided with the second electrode 51.

[0142] The second electrode 51, together with the first electrode 41, is used to determine whether the light-emitting structure 31 emits light. Based on this, the embodiment of the present application places the light-reflecting portion Z2 in the same layer as the second electrode 51, thereby reducing the impact of the light-reflecting portion Z2 on the overall thickness of the display panel, and contributing to the realization of a thinner design for the display panel.

[0143] Alternatively, the light-reflecting portion Z2 and the second electrode 51 may be made of the same material, i.e., they may be fabricated together in the same manufacturing process, thereby simplifying the manufacturing process of the film layers in the display panel and improving the manufacturing efficiency of the display panel.

[0144] Alternatively, in another embodiment, the substrate 10 includes a metal layer, and the light reflecting portion Z2 is located on the metal layer. The metal layer included in the substrate 10 may be a metal layer on which signal lines are located, such as a data signal line, a reference voltage data line, a power signal line, etc.

[0145] In a second aspect, referring to FIG. 12, an embodiment of the present application provides a display device including the display panel of any of the above embodiments.

[0146] The display device according to the examples of the present application has the beneficial effects of the display panel in any of the above-described embodiments, and for specific details, please refer to the explanation of the beneficial effects of the display panel, and the explanation will be omitted in the examples of the present application.

[0147] The embodiments disclosed in the present application are as described above, but the above contents are merely embodiments adopted to facilitate understanding of the present application and are not used to limit the present application. A person skilled in the art to which the present application pertains can make any modifications and changes in the embodiments and details without departing from the spirit and scope of the present application.
