[0002] Organic Light Emitting Diode (OLED) display technology is considered the most promising new display technology for the next generation. Compared with liquid crystal display technology, OLED display technology has advantages such as low energy consumption, low cost, self-luminescence, wide viewing angle, and fast response speed.

[0003] Traditionally, pixel patterning is achieved using a fine metal mask (FMM) during the production of OLED display panels. FMM technology is mature and boasts extensive mass production experience. However, it also suffers from limitations such as limited precision and high cost.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0026] It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined or explained in subsequent figures. It should be noted that different features in the embodiments of the present application can be combined with each other without conflict.

[0027] Furthermore, when terms such as "upper," "above," "lower," "below," and "relatively" are used to define the relative position of two elements, this includes not only a state in which the two elements are directly in contact but also a state in which the two elements are separated by a gap or other elements. Furthermore, terms such as "first," "second," and "third" are used solely for purposes of distinction and description and should not be construed as indicating or implying relative importance.

[0028] It should be noted that, in the absence of conflict, different features in the embodiments of the present application can be combined with each other.

[0029] Increasing the density of light-emitting units (i.e., pixel density) in display panels is an important approach to improving display quality. However, current display panels manufactured using fine metal evaporation mask (FMM) technology are currently unable to achieve further increases in light-emitting unit density due to technical limitations. The inventors have discovered, through extensive research, that to address this technical issue, isolation structures can be incorporated into some display panels. During the full-layer evaporation of the light-emitting layer and the second electrode, these can be disconnected at the isolation structures. Through multiple evaporation and etching processes (i.e., light-emitting unit patterning), light-emitting units of different colors can be formed in different isolation openings.

[0030] The display panel in the related technology includes a substrate, a light-emitting unit located on one side of the substrate, and a touch layer located on the side of the light-emitting unit away from the substrate. The touch layer includes a plurality of touch electrodes arranged at intervals, a non-functional wiring located between two adjacent touch electrodes, and a touch wiring located between two adjacent non-functional wirings. The touch wiring is electrically connected to the corresponding touch electrodes. In order to insulate the adjacent touch wiring from the non-functional wiring, a break is provided between the adjacent touch wiring and the non-functional wiring. In order to insulate the adjacent touch electrodes from the non-functional wiring, a break is also provided between the adjacent touch electrodes and the non-functional wiring.

[0031] In this way, the break between two adjacent touch electrodes includes the break between the adjacent touch electrodes and the non-functional wiring, as well as the break between the adjacent touch wiring and the non-functional wiring. Therefore, the number of breaks between two adjacent touch electrodes is relatively large. When the light emitted by the light-emitting unit is irradiated on the cross-section of the break, the cross-section of the break will reflect light, so that the bright line formed by the break between the two adjacent touch electrodes can be seen on the display panel, thereby affecting the display effect of the display panel.

[0032] In order to solve the above-mentioned technical problems, the following technical solutions are innovatively designed. The specific implementation solutions of this application will be described in detail below with reference to the accompanying drawings. It should be noted that the defects existing in the solutions in the above-mentioned prior art are the results obtained after practice and careful study. Therefore, the discovery process of the above-mentioned technical problems and the solutions proposed in the following embodiments for the above-mentioned problems should all be contributions made to this application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0033] See Figure 1-Figure 3 This embodiment provides a display panel, which includes a substrate 4, a pixel defining layer 9, a light-emitting unit 8 and a touch layer 10.

[0034] The display panel may be an organic light emitting diode (OLED) display panel or a quantum dot light emitting diode (QLED) display panel.

[0035] See Figure 4 The substrate 4 includes a pixel circuit 17 layer and a planarization layer 16. The pixel circuit 17 layer includes a pixel circuit 17 for driving the light-emitting unit 8 to emit light. Figure 4 The transistors in pixel circuit 17 are shown. Vias are provided in planarization layer 16, and first electrode 5 of light-emitting unit 8 is electrically connected to the transistors in pixel circuit 17 through the vias. Furthermore, pixel circuit 17 includes at least one insulating layer, which may include at least one of an inorganic layer and an organic layer. Furthermore, substrate 4 includes scan lines that provide scan signals Scan and data lines that provide data signals Data to pixel circuit 17.

[0036] See Figure 5 The pixel circuit 17 includes a driving transistor T1 and a data transistor T2, a first electrode of the data transistor T2 is connected to a data line providing a data signal Data, a gate of the data transistor T2 is connected to a scan line providing a scan signal Scan, a second electrode of the data transistor T2 is connected to the gate of the driving transistor T1, two ends of the storage capacitor C1 are respectively connected to the gate and the first electrode of the driving transistor T1, and the second electrode of the driving transistor T1 is connected to the light-emitting unit 8. Figure 5 This is an embodiment of the pixel circuit 17. The pixel circuit 17 of the present application is not limited to Figure 5 The 2T1C pixel circuit 17 shown may also be other pixel circuits 17, such as a 7T1C, 8T1C pixel circuit 17, etc.

[0037] The pixel defining layer 9 is located on one side of the substrate 4 , and the pixel defining layer 9 has a plurality of pixel openings 91 .

[0038] At least a portion of the light emitting unit 8 is located within the pixel opening 91 .

[0039] The touch layer 10 is located on the side of the light-emitting unit 8 away from the substrate 4. The touch layer 10 includes a plurality of touch electrodes 1 arranged at intervals and a touch trace 2 located between two touch electrodes 1. The touch trace 2 is electrically connected to the corresponding touch electrode 1, and there are a plurality of first breaks 3 between the touch trace 2 and the touch electrode 1.

[0040] In the related art, there are non-functional traces between the touch traces 2 and the touch electrodes 1 , and therefore, there are a large number of breaks between adjacent touch traces 2 .

[0041] In this embodiment, without affecting the insulation of adjacent touch electrodes 1, the non-functional wiring between the touch wiring 2 and the touch electrode 1 is eliminated. In this way, the break between two adjacent touch electrodes 1 only includes the first break 3 between the adjacent touch electrode 1 and the touch wiring 2, which at least reduces the number of breaks between the touch wiring 2 and the non-functional wiring in the related art, thereby greatly reducing the number of breaks between two adjacent touch electrodes 1.

[0042] Since the number of breaks between two adjacent touch electrodes 1 is reduced, when the light-emitting unit 8 emits light, it is not easy to see bright lines generated by multiple first breaks 3 on the display panel, thereby greatly improving the display effect of the display panel.

[0043] Based on the above design, in this embodiment, by setting multiple first breaks 3 between the touch trace 2 and the touch electrode 1, the non-functional traces between the touch electrode 1 and the touch trace 2 can be eliminated, thereby reducing the number of breaks between two adjacent touch electrodes 1, and it is not easy to see bright lines generated by multiple first breaks 3 on the display panel, which can greatly improve the display effect of the display panel.

[0044] In some possible implementations, the display panel further includes a chip, and the chip is electrically connected to a touch trace 2. One end of the touch trace 2 is electrically connected to the chip, and the other end is electrically connected to the corresponding touch electrode 1. In this way, the electrical signal from the chip can be transmitted to the corresponding touch electrode 1 via the touch trace 2.

[0045] Optionally, the touch electrode 1 is configured as a self-capacitive touch electrode 1. The touch electrode 1 can receive touch signals and can also send touch signals.

[0046] For some possible implementations, see Figure 2 and Figure 6 , the orthographic projections of at least some of the multiple first breaks 3 on the substrate 4 are close to the boundary angle of the orthographic projection of the pixel opening 91 on the substrate 4 .

[0047] In the related art, the break is located at the edge of the pixel opening 91. In this way, the distance between the break and the pixel opening 91 is relatively close, and the light emitted by the light-emitting unit 8 is easily reflected when it is irradiated on the cross-section of the break, making it easier to see the bright lines generated by multiple breaks.

[0048] In this embodiment, the first break 3 is set at the boundary angle of the pixel opening 91. For example, when the positive projection of the pixel opening 91 on the substrate 4 is a rectangle, the first break 3 is set at any one of the four corners of the rectangle. In this way, the distance between the first break 3 and the pixel opening 91 can be increased. When the light emitted by the light-emitting unit 8 is irradiated on the cross-section of the first break 3, the cross-section of the first break 3 is not easy to reflect light, or the light reflected by the cross-section of the first break 3 is weak. Therefore, it is less likely to see the bright lines generated by multiple first breaks 3 on the display panel, thereby further improving the display effect of the display panel.

[0049] Optionally, the orthographic projection of the touch electrode 1 on the substrate 4 surrounds at least a portion of the orthographic projection of the pixel opening 91 on the substrate 4 .

[0050] Optionally, the orthographic projection of the touch trace 2 on the substrate 4 surrounds at least a portion of the orthographic projection of the pixel opening 91 on the substrate 4 .

[0051] Optionally, the orthographic projection of the touch electrode 1 on the substrate 4 and the orthographic projection of the pixel opening 91 on the substrate 4 are spaced apart.

[0052] Optionally, the orthographic projection of the touch trace 2 on the substrate 4 and the orthographic projection of the pixel opening 91 on the substrate 4 are spaced apart.

[0053] In this way, the touch electrodes 1 and the touch traces 2 are unlikely to block the light emitted by the light-emitting unit 8 , thereby not affecting the display effect of the display panel.

[0054] For some possible implementations, see again Figure 2 and Figure 6 The minimum distance D between the center of the orthographic projection of the first break 3 on the substrate 4 and the edge of the orthographic projection of the pixel opening 91 on the substrate 4 is greater than or equal to 7 μm and less than or equal to 10 μm. For example, the minimum distance D can be 7 μm, 8 μm, 9 μm, or 10 μm. By properly setting the minimum distance D, the bright lines generated by the multiple first breaks 3 can be less visible on the display panel.

[0055] For some possible implementations, see Figure 2 and Figure 7a The first fracture 3 includes a first section 21, the touch trace 2 includes a first section 21, the first section 21 is arranged opposite to the side wall of the touch electrode 1 facing the first section 21, the first section 21 is a side surface along the width direction of the touch trace 2, and the side wall of the touch electrode 1 is a side surface along the extension direction of the touch electrode 1.

[0056] The fracture in the related art includes two sections set opposite to each other, and both sections of the fracture can reflect the light emitted by the light-emitting unit 8. Therefore, the light of the light-emitting unit 8 reflected by the fracture in the related art is stronger, making it easier to see the bright lines generated by multiple fractures on the display panel.

[0057] In this embodiment, at least some of the multiple first breaks 3 include a first section 21 located on the touch trace 2. The first section 21 corresponds to the sidewall of the touch electrode 1. The sidewall of the touch electrode 1 is not easily reflective or reflects little light. Light emitted by the light-emitting unit 8 is primarily reflected by the first section 21. Thus, compared to related art, this embodiment eliminates one reflective section, thereby reducing light reflection from the first break 3 and making the bright lines formed by the multiple first breaks 3 less visible on the display panel.

[0058] For some possible implementations, see again Figure 2 and Figure 7a The first fracture 3 includes a second section 101, the touch electrode 1 includes a second section 101, the second section 101 and the side wall of the touch trace 2 facing the second section 101 are arranged opposite to each other, the second section 101 is a side surface along the width direction of the touch electrode 1, and the side wall of the touch trace 2 is a side surface along the extension direction of the touch trace 2.

[0059] Similarly, in this embodiment, at least some of the multiple first breaks 3 include second sections 101 located on the touch electrode 1. The second sections 101 correspond to the sidewalls of the touch traces 2. The sidewalls of the touch traces 2 are not prone to light reflection or reflect very little light. Light emitted by the light-emitting unit 8 is primarily reflected by the second sections 101. Thus, compared to related art, this embodiment eliminates one reflective section, resulting in even less light reflected by the second breaks 15, making the bright lines formed by the multiple first breaks 3 less visible on the display panel.

[0060] It is worth noting that the touch trace 2 includes a first surface close to the substrate 4, a second surface away from the substrate 4, and a side surface connected between the first surface and the second surface, wherein the first section 21 is a side surface along the width direction of the touch trace 2 and opposite to the touch electrode 1, and the side wall of the touch trace 2 is a side surface along the extension direction of the touch trace 2.

[0061] The touch electrode 1 includes a third surface close to the substrate 4, a fourth surface away from the substrate 4, and a side surface connected between the third surface and the fourth surface, wherein the second section 101 is a side surface along the width direction of the touch electrode 1 and opposite to the touch trace 2, and the side wall of the touch electrode 1 is a side surface along the extension direction of the touch electrode 1.

[0062] For some possible implementations, see Figure 2 、 Figure 7a and Figure 7b The multiple first breaks 3 include first-type first breaks and second-type first breaks, the first-type first breaks include the first section 21, or the first-type first breaks include the second section 101; the second-type first breaks include the third section 22 and the fourth section 102, the touch trace 2 includes the third section 22, the touch electrode 1 includes the fourth section 102, and the third section 22 and the fourth section 102 are arranged opposite to each other.

[0063] Optionally, the number of the first-type first breaks is greater than the number of the second-type first breaks.

[0064] If the two cross sections of the first break 3 are arranged opposite to each other, the light reflected by the first break 3 is more concentrated, and the bright line formed by the first break 3 is more easily visible on the display panel.

[0065] In this embodiment, the number of first breaks of the first type is greater than the number of first breaks of the second type, that is, the number of first breaks 3 with two sections set opposite to each other is less than the number of first breaks 3 with the sections staggered. In this way, the first section 21 and the second section 101 can be dispersed, thereby dispersing the reflection of the first break 3, and making it less likely to see the bright line formed by the first break 3 in the display panel.

[0066] Optionally, the first section 21 is perpendicular to a portion of the second section 101. In this way, the first section 21 and the second section 101 can be further dispersed.

[0067] For some possible implementations, see again Figure 2 and Figure 7a The touch traces 2 enclose a semi-enclosed structure, and the touch electrodes 1 extend into the semi-enclosed structure.

[0068] The orthographic projection of a portion of the touch electrode 1 on the substrate 4 is located between the orthographic projections of two oppositely disposed first sections 21 on the substrate 4 .

[0069] The two first sections 21 are separated by the touch electrode 1, and the touch electrode 1 extends into a semi-enclosed structure formed by the touch trace 2. The second section 101 on the touch electrode 1 extends to be arranged opposite to the touch trace 2. In this way, the first section 21 and the second section 101 can be dispersed, thereby further dispersing the light reflected by the first section 3.

[0070] Optionally, the orthographic projection of the semi-enclosed structure formed by the touch traces 2 on the substrate 4 surrounds the orthographic projections of at least two pixel openings 91 on the substrate 4. In this way, the number of first breaks between adjacent touch traces 2 and touch electrodes 1 can be further reduced.

[0071] Optionally, the orthographic projection of the touch electrode 1 extending into the semi-enclosed structure on the substrate 4 is located between the orthographic projections of two adjacent pixel openings 91 on the substrate 4, and the orthographic projections of two adjacent pixel openings 91 on the substrate 4 are located within the orthographic projection of the semi-enclosed structure on the substrate 4. In this way, the touch electrode 1 extending into the semi-enclosed structure is less likely to block the light emitted by the light-emitting unit 8, thereby not affecting the display effect of the display panel.

[0072] For some possible implementations, see again Figure 2 and Figure 7a , one pixel opening 91 corresponds to one first section 21 and one second section 101 , or one pixel opening 91 corresponds to two second sections 101 .

[0073] In the related art, one pixel opening 91 corresponds to two fractures, and each fracture includes two relatively arranged cross sections. Therefore, one pixel opening 91 corresponds to four cross sections. In this way, the light generated by one light-emitting unit 8 is reflected by the four cross sections, so that the bright lines generated by multiple fractures can be more easily seen in the display panel.

[0074] In this embodiment, one pixel opening 91 corresponds to one first section 21 and one second section 101, or one pixel opening 91 corresponds to two second sections 101. In this way, one light-emitting unit 8 corresponds to two sections, which reduces the number of sections corresponding to one light-emitting unit 8, thereby reducing the light reflected by the section corresponding to one light-emitting unit 8, and further improving the problem of forming bright lines in the display panel.

[0075] Optionally, a first section 21 and a second section 101 corresponding to a pixel opening 91 are perpendicular to each other.

[0076] Optionally, one pixel opening 91 corresponds to two second sections 101 that are perpendicular to each other.

[0077] In this way, one light-emitting unit 8 not only corresponds to only two sections, but the two sections are perpendicular to each other, which not only reduces the light reflected by the sections but also disperses the light reflected by the sections, making it less likely that the bright lines formed by the sections will be visible in the display panel.

[0078] For some possible implementations, see again Figure 2 The orthographic projections of the touch traces 2 on the substrate 4 are staggered with the orthographic projections of the touch electrodes 1 on the substrate 4. In this way, the first breaks 3 between the touch traces 2 and the touch electrodes 1 are more dispersed, and the bright lines formed by the breaks are less visible on the display panel.

[0079] For some possible implementations, see again Figure 2 The touch electrode 1 includes a plurality of second breaks 15 .

[0080] Optionally, per unit area, the ratio of the absolute value of the difference between the number of first breaks 3 and the number of second breaks 15 to the number of second breaks 15 is less than or equal to 5%. For example, the ratio may be 5%, 4%, 3%, 2%, 1%, or 0.

[0081] In this way, the difference in the number of the first breaks 3 and the second breaks 15 can be reduced, thereby reducing the difference in light reflected from the first breaks 3 and the second breaks 15 , thereby improving the display uniformity of the display panel.

[0082] Optionally, per unit area, the number of the first breaks 3 is equal to the number of the second breaks 15. In this way, the display uniformity of the display panel can be further improved.

[0083] For some possible implementations, see Figure 8 The display panel also includes an isolation structure 11, which is located between the pixel defining layer 9 and the touch layer 10. The isolation structure 11 encloses a plurality of isolation openings, which are connected to the corresponding pixel openings 91. At least part of the light-emitting unit 8 is located within the isolation opening. The light-emitting unit 8 includes a first electrode 5, a light-emitting functional portion 6, and a second electrode 7 that are sequentially stacked in a direction away from the substrate 4.

[0084] Optionally, the isolation structure 11 can also enclose a plurality of light-transmitting openings, which can be arranged in the entire display area of ​​the display panel or only in the light-transmitting area of ​​the display panel. In this way, the overall transmittance of the display panel can be improved, and related functions of the under-screen photosensitive device can be realized, such as realizing the camera function.

[0085] The provision of the isolation structure 11 enables the display panel to form film layers of light-emitting units 8 of different colors in different isolation openings without the need for a fine mask. When forming the light-emitting material layer, the light-emitting material layer is separated by the isolation structure 11 to form multiple spaced light-emitting functional units 6. When forming the second electrode material layer, the second electrode material layer is separated by the isolation structure 11 to form multiple spaced second electrodes 7. The isolation structure 11 comprises a conductive material, and the second electrodes 7 are electrically connected to the isolation structure 11. One first electrode 5, one light-emitting functional unit 6, and one second electrode 7 form one light-emitting unit 8. The first electrode 5 can be an anode, and the second electrode 7 can be a cathode.

[0086] In this way, different light-emitting units 8 can be made independent of each other, thereby reducing crosstalk between adjacent light-emitting units 8 and improving the display effect of the display panel. At the same time, due to the presence of the isolation structure 11, the light-emitting material layer and the second electrode material layer in the light-emitting unit 8 of each color in the display panel can be first prepared on the entire surface and then patterned, thereby eliminating the need for a fine mask and further reducing the production cost of the display panel.

[0087] Specifically, the isolation opening includes a first isolation opening, a second isolation opening and a third isolation opening, the light-emitting unit 8 includes a first light-emitting unit, a second light-emitting unit and a third light-emitting unit with different light-emitting colors, at least part of the first light-emitting unit is located in the first isolation opening, at least part of the second light-emitting unit is located in the second isolation opening, and at least part of the third light-emitting unit is located in the third isolation opening.

[0088] The pixel defining layer 9 is provided with a first pixel opening communicating with the first isolation opening, a second pixel opening communicating with the second isolation opening, and a third pixel opening communicating with the third isolation opening. The orthographic projections of the first, second, and third pixel openings on the substrate 4 may be the same or different in area. The orthographic projections of the pixel opening 91 and the corresponding isolation opening on the substrate 4 may have the same or different shapes.

[0089] Generally speaking, the area of ​​the orthographic projection of the isolation opening on substrate 4 is larger than the area of ​​the orthographic projection of the pixel opening 91 connected to the isolation opening on substrate 4, and the orthographic projection of the pixel opening 91 of the light-emitting unit 8 on substrate 4 overlaps with the orthographic projection of the isolation opening on substrate 4. The pixel defining layer 9 is made of an inorganic material, for example, the pixel defining layer 9 is formed using at least one inorganic insulating material selected from silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxynitride (SiON).

[0090] In another embodiment, the isolation structure 11 is arranged in the groove of the pixel defining layer 9; or the pixel defining layer 9 may not be arranged in the display panel, and the isolation structure 11 is arranged on one side of the substrate 4, and the isolation structure 11 is arranged in contact with one side of the substrate 4.

[0091] The first, second, and third light-emitting units each emit light of a different color; each of the first, second, and third light-emitting units includes a first electrode 5, a light-emitting functional portion 6, and a second electrode 7, which are stacked. The first electrode 5 is disposed on a substrate 4, with a pixel defining layer 9 covering the end of the first electrode 5. The pixel defining layer 9 is provided with a pixel opening 91, through which the first electrode 5 is exposed. The light-emitting functional portions 6 of the first, second, and third light-emitting units cover the sidewalls of the pixel opening 91 of the pixel defining layer 9 and the side of the pixel defining layer 9 facing away from the substrate 4. Each light-emitting functional portion 6 is located within the pixel opening 91 and in contact with the first electrode 5.

[0092] The second electrodes 7 of the first light emitting unit, the second light emitting unit, and the third light emitting unit respectively cover the corresponding light emitting functional parts 6 , and the second electrodes 7 are electrically connected to the isolation structure 11 .

[0093] The first electrode 5 of each light-emitting unit 8 may be connected to the pixel circuit 17 through a via hole, so that the pixel circuit 17 drives the corresponding light-emitting unit 8 to emit light.

[0094] The first electrode 5 may include a multilayer structure. For example, the first electrode 5 may include a reflective layer and a pair of conductive oxide layers covering the upper and lower surfaces of the reflective layer, respectively. The reflective layer may be formed using, for example, a metal material with excellent light reflectivity, such as silver. The conductive oxide layers may be formed using, for example, a transparent conductive oxide such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), or IGZO (Indium Gallium Zinc Oxide). The second electrode 7 may be formed using, for example, a metal material such as a magnesium and silver alloy (MgAg).

[0095] Figure 9 This is a schematic diagram of a light-emitting functional unit 6 according to one embodiment of the present application. The light-emitting functional unit 6 of at least one of the first, second, and third light-emitting units 8 includes a hole injection layer HIL, a hole transport layer HTL, an electron blocking layer EBL, a light-emitting material layer EML, a hole blocking layer HBL, an electron transport layer ETL, and an electron injection layer EIL, stacked in a direction away from the substrate 4. The light-emitting functional unit 6 may include a single light-emitting material layer EML, or a stacked light-emitting functional unit 6 including multiple light-emitting material layers EML.

[0096] To enable the light-emitting functional portion 6 to emit light, a pixel voltage is supplied to the first electrode 5 and a common voltage is supplied to the second electrode 7, respectively. This creates a potential difference between the first electrode 5 and the second electrode 7, causing the light-emitting functional portion 6 disposed therebetween to emit light. In one embodiment, if a potential difference is formed between the first electrode 5 and the second electrode 7 of the first light-emitting unit, the light-emitting material layer EML of the light-emitting functional portion 6 emits blue light. If a potential difference is formed between the first electrode 5 and the second electrode 7 of the second light-emitting unit, the light-emitting material layer EML of the light-emitting functional portion 6 emits green light. If a potential difference is formed between the first electrode 5 and the second electrode 7 of the third light-emitting unit, the light-emitting material layer EML of the light-emitting functional portion 6 emits red light.

[0097] The pixel voltage of the first electrode 5 is provided by the pixel circuit 17, and the common voltage of the second electrode 7 is provided by the isolation structure 11. Specifically, the second electrode 7 is electrically connected to the isolation structure 11. By providing the common voltage to the isolation structure 11, the common voltage is supplied to the second electrode 7. In other words, the isolation structure 11 has the function of supplying the common voltage to the second electrode 7.

[0098] Optionally, the orthographic projection of the touch electrode 1 on the substrate 4 surrounds at least a portion of the orthographic projection of the isolation opening on the substrate 4 .

[0099] Optionally, the orthographic projection of the touch trace 2 on the substrate 4 surrounds at least a portion of the orthographic projection of the isolation opening on the substrate 4 .

[0100] Optionally, the orthographic projection of the touch electrode 1 on the substrate 4 and the orthographic projection of the isolation opening on the substrate 4 are spaced apart.

[0101] Optionally, the orthographic projection of the touch trace 2 on the substrate 4 and the orthographic projection of the isolation opening on the substrate 4 are spaced apart.

[0102] In this way, the touch electrodes 1 and the touch traces 2 are unlikely to block the light emitted by the light-emitting unit 8 , thereby not affecting the display effect of the display panel.

[0103] In some possible embodiments, the display panel further includes a plurality of packaging units 12, which are located between the light-emitting unit 8 and the touch layer 10, and a portion of the packaging unit 12 extends from the side of the isolation structure 11 toward the isolation opening to the side of the isolation structure 11 away from the substrate 4.

[0104] Optionally, the multiple encapsulation units 12 corresponding to the multiple light-emitting units 8 are arranged at intervals.

[0105] Optionally, a gap exists between the packaging unit 12 located on the side of the isolation structure 11 away from the substrate 4 and the side of the isolation structure 11 away from the substrate 4 .

[0106] During the patterning process of the light-emitting unit 8 , the first packaging material layer is disconnected at the isolation structure 11 to form the packaging unit 12 . The packaging unit 12 can completely and independently package the corresponding light-emitting unit 8 , thereby improving the display characteristics of the display panel.

[0107] For some possible implementations, see Figure 10 The display panel further includes a second encapsulation layer 13 located on a side of the encapsulation unit 12 away from the substrate 4 and a third encapsulation layer 14 located on a side of the second encapsulation layer 13 away from the substrate 4 . The touch layer 10 is located on a side of the third encapsulation layer 14 away from the substrate 4 .

[0108] Optionally, the materials of the encapsulation unit 12 and the third encapsulation layer 14 both include inorganic materials; Optionally, the material of the second encapsulation layer 13 includes an organic material.

[0109] For example, the encapsulation unit 12 and the third encapsulation layer 14 can be formed by chemical vapor deposition (CVD), and the second encapsulation layer 13 can be formed by inkjet printing (IJP). The second encapsulation layer 13 and the third encapsulation layer 14 can provide a better encapsulation effect on the light-emitting unit 8, thereby further improving the encapsulation quality of the display panel.

[0110] Specifically, the material of the encapsulation unit 12 and the third encapsulation layer 14 includes at least one of silicon nitride (SiN), silicon oxide (SiO), and silicon oxynitride (SiON). The second encapsulation layer 13 is an organic insulating material, such as epoxy resin, acrylic resin, or other resin material.

[0111] For some possible implementations, see again Figure 8 The isolation structure 11 includes a first isolation portion 111 and a second isolation portion 112 stacked in sequence along a direction away from the substrate 4. The orthographic projection of the side of the first isolation portion 111 away from the substrate 4 on the substrate 4 is located within the orthographic projection of the second isolation portion 112 on the substrate 4. The orthographic projection area of ​​the side of the first isolation portion 111 away from the substrate 4 on the substrate 4 is smaller than the orthographic projection area of ​​the second isolation portion 112 on the substrate 4. The second electrode 7 of the light-emitting unit 8 is electrically connected to the first isolation portion 111.

[0112] Since the second isolation portion 112 is located on the side of the first isolation portion 111 away from the substrate 4, and the lateral width of the second isolation portion 112 is greater than the lateral width of the first isolation portion 111, the two ends of the second isolation portion 112 are protruded compared to the side of the first isolation portion 111. The shape of this isolation structure 11 is also called an overhang. Therefore, when forming a light-emitting material layer, the light-emitting material layer will be separated by the second isolation portion 112 to form a plurality of spaced-apart light-emitting functional portions 6. When forming a second electrode material layer, the second electrode material layer will be separated by the second isolation portion 112 to form a plurality of spaced-apart second electrodes 7.

[0113] The first isolation portion 111 includes a conductive material. The second electrode 7 corresponding to the light emitting unit 8 extends to contact the sidewall of the first isolation portion 111 to achieve electrical connection between the second electrode 7 corresponding to the light emitting unit 8 and the first isolation portion 111 .

[0114] Preferably, see again Figure 10 The isolation structure 11 further includes a third isolation portion 113 located on a side of the first isolation portion 111 facing the substrate 4 , and the second electrode 7 of the light emitting unit 8 is electrically connected to the third isolation portion 113 .

[0115] Optionally, the material of the third isolation portion 113 includes molybdenum or titanium; and / or the material of the first isolation portion 111 includes aluminum, silver or copper; and / or the material of the second isolation portion 112 includes titanium or molybdenum.

[0116] The third isolation portion 113 includes a conductive material. The second electrode 7 corresponding to the light emitting unit 8 extends to contact the sidewall of the third isolation portion 113 to achieve electrical connection between the second electrode 7 corresponding to the light emitting unit 8 and the third isolation portion 113 .

[0117] In summary, the present application eliminates the non-functional wiring between the touch electrode 1 and the touch wiring 2, sets the first break 3 at the chamfer of the pixel opening 91, reduces the number of cross-sections of the first break 3, reduces the number of cross-sections corresponding to one light-emitting unit 8, disperses the cross-sections of the first break 3, and increases the distance between the cross-section of the first break 3 and the pixel opening 91, etc., so that it is not easy to see bright lines generated by multiple first breaks 3 on the display panel, thereby greatly improving the display effect of the display panel.

[0118] For some possible implementations, see Figure 8 and Figure 11 , the present application also provides a method for preparing a display panel, the method comprising: S10: providing a substrate 4.

[0119] S11 : forming a pixel defining layer 9 on one side of the substrate 4 , wherein the pixel defining layer 9 has a plurality of pixel openings 91 .

[0120] S12 : forming a light emitting unit 8 , wherein at least a portion of the light emitting unit 8 is located within the pixel opening 91 .

[0121] S13: A touch layer 10 is formed on a side of the light-emitting unit 8 away from the substrate 4. The touch layer 10 includes a plurality of touch electrodes 1 arranged at intervals and a touch trace 2 located between at least some adjacent two touch electrodes 1. The touch trace 2 is electrically connected to the corresponding touch electrode 1, and a plurality of first breaks 3 are provided between the touch trace 2 and the touch electrode 1.

[0122] In the display panel formed by the above method, the non-functional wiring between the touch wiring 2 and the touch electrode 1 is eliminated without affecting the insulation of the adjacent touch electrodes 1. In this way, the break between two adjacent touch electrodes 1 only includes the first break 3 between the adjacent touch electrode 1 and the touch wiring 2, which at least reduces the number of breaks between the touch wiring 2 and the non-functional wiring in the related art, thereby greatly reducing the number of breaks between two adjacent touch electrodes 1.

[0123] Since the number of breaks between two adjacent touch electrodes 1 is reduced, when the light-emitting unit 8 emits light, it is not easy to see bright lines generated by multiple first breaks 3 on the display panel, thereby greatly improving the display effect of the display panel.

[0124] One end of the touch trace 2 is electrically connected to the chip, and the other end is electrically connected to the corresponding touch electrode 1. In this way, the electrical signal of the chip can be transmitted to the corresponding touch electrode 1 through the touch trace 2. The touch electrode 1 is configured as a self-capacitive touch electrode 1. The touch electrode 1 can receive touch signals and also send touch signals.

[0125] In some possible implementations, the step of forming the pixel defining layer 9 on one side of the substrate 4 includes: A pixel defining layer 9 is formed on one side of the substrate 4 , and an isolation structure 11 is formed on a side of the pixel defining layer 9 away from the substrate 4 .

[0126] Specifically, a first electrode 5 is formed on one side of the substrate 4, and a pixel defining material layer and an isolation material layer are sequentially formed on the side of the first electrode 5 away from the substrate 4. The isolation material layer and the pixel defining material layer are patterned in sequence to form an isolation structure 11 and a pixel defining layer 9, respectively. The isolation structure 11 encloses a plurality of isolation openings, which are connected to the corresponding pixel openings 91. A pixel opening 91 exposing a portion of the first electrode 5 is provided on the pixel defining layer 9, and the pixel opening 91 is connected to the isolation opening.

[0127] In some possible implementations, the isolation opening includes a first isolation opening and a second isolation opening, and the step of forming the light-emitting unit 8 includes: A light-emitting material layer of the first light-emitting unit, a second electrode material layer and a first packaging material layer are sequentially formed on a side of the isolation structure 11 away from the substrate 4 .

[0128] The light-emitting material layer will be disconnected at the isolation structure 11, so that at least part of the light-emitting material layer of the first light-emitting unit is located in the first isolation opening to form the light-emitting functional part 6 of the first light-emitting unit. By controlling the evaporation angle, the light-emitting functional part 6 of the first light-emitting unit can be prevented from contacting the isolation structure 11.

[0129] The second electrode material layer of the first light-emitting unit will be disconnected at the isolation structure 11, so that at least part of the second electrode material layer of the first light-emitting unit is located in the first isolation opening to form the second electrode 7 of the first light-emitting unit. By controlling the evaporation angle, the second electrode 7 of the first light-emitting unit can be extended from the isolation opening to electrically contact the isolation structure 11.

[0130] A first etching protection layer is formed in the first isolation opening corresponding to the first light-emitting unit. The first etching protection layer also extends to cover part of the isolation structure 11. The first etching protection layer can protect the corresponding light-emitting material layer, the second electrode material layer and the first packaging material layer of the first light-emitting unit.

[0131] The first packaging material layer, the light-emitting material layer and the second electrode material layer of the first light-emitting unit not covered by the first etching protection layer are removed, and the first etching protection layer is removed to form the light-emitting functional part 6, the second electrode 7 and the packaging unit 12 of the first light-emitting unit in the first isolation opening, and the second electrode 7 extends to be electrically connected to the isolation structure 11 corresponding to the first light-emitting unit.

[0132] After removing the first packaging material layer, the light-emitting material layer and the second electrode material layer that are not covered by the first etching protection layer, the first electrode 5, the light-emitting functional part 6 of the first light-emitting unit and the second electrode 7 form a first light-emitting unit, and the first light-emitting unit is completely covered by the packaging unit 12, thereby reducing the risk of the evaporation material entering the evaporation equipment after being exposed to the air, causing equipment contamination and film layer disconnection.

[0133] In this way, the light-emitting functional part 6, the second electrode 7 and the packaging unit 12 of the first light-emitting unit can be formed only in the first isolation opening corresponding to the first light-emitting unit without the need for a precise mask, and the second electrode 7 can be electrically connected to the isolation structure 11, so that the first light-emitting unit can be formed in the first isolation opening corresponding to the first light-emitting unit at a lower cost.

[0134] At least a portion of the second light emitting unit is formed in the second isolation opening by the above method.

[0135] Optionally, see again Figure 2 and Figure 6The orthographic projections of at least some of the plurality of first breaks 3 on the substrate 4 are located at the chamfers of the orthographic projections of the pixel opening 91 on the substrate 4 .

[0136] The first break 3 is set at the chamfer position of the pixel opening 91. For example, when the positive projection of the pixel opening 91 on the substrate 4 is a rectangle, the first break 3 is set at any one of the four corners of the rectangle. In this way, the distance between the first break 3 and the pixel opening 91 can be increased. When the light emitted by the light-emitting unit 8 is irradiated on the cross-section of the first break 3, the cross-section of the first break 3 is not easy to reflect light, or the light reflected by the cross-section of the first break 3 is weak. Therefore, it is less likely to see the bright lines generated by multiple first breaks 3 on the display panel, thereby further improving the display effect of the display panel.

[0137] Optionally, see again Figure 2 and Figure 6 The minimum distance D between the center of the orthographic projection of the first break 3 on the substrate 4 and the edge of the orthographic projection of the pixel opening 91 on the substrate 4 is greater than or equal to 7 μm and less than or equal to 10 μm. For example, the minimum distance D can be 7 μm, 8 μm, 9 μm, or 10 μm. By properly setting the minimum distance D, the bright lines generated by the multiple first breaks 3 can be less visible on the display panel.

[0138] Alternatively, see Figure 2 and Figure 7a The first fracture 3 includes a first section 21 , the touch trace 2 includes the first section 21 , and the first section 21 is arranged opposite to a side wall of the touch electrode 1 facing the first section 21 .

[0139] The fracture in the related art includes two sections set opposite to each other, and both sections of the fracture can reflect the light emitted by the light-emitting unit 8. Therefore, the light of the light-emitting unit 8 reflected by the fracture in the related art is stronger, making it easier to see the bright lines generated by multiple fractures on the display panel.

[0140] In this embodiment, at least some of the multiple first breaks 3 include only the first section 21 located on the touch trace 2. The first section 21 corresponds to the sidewall of the touch electrode 1, which is not easily reflective. Light emitted by the light-emitting unit 8 is primarily reflected by the first section 21. Thus, compared to related art, this embodiment eliminates one reflective section, resulting in less light reflected by the first break 3, making the bright lines formed by the multiple first breaks 3 less visible on the display panel.

[0141] Optionally, see again Figure 2 and Figure 7aThe first fracture 3 includes a second section 101 , the touch electrode 1 includes the second section 101 , and the second section 101 is arranged opposite to a side wall of the touch trace 2 facing the second section 101 .

[0142] Similarly, in this embodiment, at least some of the multiple first breaks 3 include only the second section 101 located on the touch electrode 1. The second section 101 corresponds to the sidewall of the touch trace 2, which is not easily reflective. Light emitted by the light-emitting unit 8 is primarily reflected by the second section 101. Thus, compared to related art, this embodiment eliminates one reflective section, resulting in less light reflected by the second break 15, making the bright line formed by the multiple first breaks 3 less visible on the display panel.

[0143] Optionally, part of the first section 21 and part of the second section 101 are perpendicular to each other.

[0144] If the two cross sections of the first break 3 are arranged opposite to each other, the light reflected by the first break 3 is more concentrated, and the bright line formed by the first break 3 is more easily visible on the display panel.

[0145] In this embodiment, the first section 21 and the second section 101 of the first break 3 are set to be perpendicular to each other, so that the first section 21 and the second section 101 can be dispersed, thereby dispersing the reflection of the first break 3, making it less likely to see the bright line formed by the first break 3 in the display panel.

[0146] Optionally, a portion of the first section 21 and a portion of the second section 101 are parallel to each other.

[0147] In some embodiments, the first section 21 and the second section 101 can also be set to be parallel to each other. In this way, the first section 21 and the second section 101 can be set according to actual conditions, thereby increasing the flexibility of setting the first section 21 and the second section 101.

[0148] Optionally, the sum of the number of mutually perpendicular first sections 21 and second sections 101 is greater than the sum of the number of mutually parallel first sections 21 and second sections 101. In this way, the reflection of the first fracture 3 can be dispersed, thereby further improving the problem of bright lines formed in the display panel.

[0149] Optionally, see again Figure 2 and Figure 7a The orthographic projection of a portion of the touch electrode 1 on the substrate 4 is located between the orthographic projections of two oppositely arranged first sections 21 on the substrate 4 .

[0150] The two first sections 21 are separated by the touch electrode 1, and the touch electrode 1 extends into the gap formed by the touch trace 2. The second section 101 on the touch electrode 1 extends to be arranged opposite to the touch trace 2. In this way, the first section 21 and the second section 101 can be dispersed, so that the light reflected by the first section 3 can be further dispersed.

[0151] Optionally, see again Figure 2 and Figure 7a , one pixel opening 91 corresponds to one first section 21 and one second section 101 , or one pixel opening 91 corresponds to two second sections 101 .

[0152] In the related art, one pixel opening 91 corresponds to two fractures, and each fracture includes two relatively arranged cross sections. Therefore, one pixel opening 91 corresponds to four cross sections. In this way, the light generated by one light-emitting unit 8 is reflected by the four cross sections, so that the bright lines generated by multiple fractures can be more easily seen in the display panel.

[0153] In this embodiment, one pixel opening 91 corresponds to one first section 21 and one second section 101, or one pixel opening 91 corresponds to two second sections 101. In this way, one light-emitting unit 8 corresponds to two sections, which reduces the number of sections corresponding to one light-emitting unit 8, thereby reducing the light reflected by the section corresponding to one light-emitting unit 8, and further improving the problem of forming bright lines in the display panel.

[0154] Optionally, a first section 21 and a second section 101 corresponding to a pixel opening 91 are perpendicular to each other.

[0155] Optionally, one pixel opening 91 corresponds to two second sections 101 that are perpendicular to each other.

[0156] In this way, one light-emitting unit 8 not only corresponds to only two sections, but the two sections are perpendicular to each other, which not only reduces the amount of light reflected by the sections but also disperses the light reflected by the sections, making it less likely that the bright lines formed by the sections will be visible in the display panel.

[0157] In summary, in the display panel formed by the above method of the present application, by eliminating the non-functional wiring between the touch electrode 1 and the touch wiring 2, by setting the first break 3 at the chamfer of the pixel opening 91, by reducing the number of cross-sections of the first break 3, by reducing the number of cross-sections corresponding to one light-emitting unit 8, by dispersing the cross-sections of the first break 3, and by increasing the distance between the cross-sections of the first break 3 and the pixel opening 91, etc., it is not easy to see bright lines generated by multiple first breaks 3 on the display panel, thereby greatly improving the display effect of the display panel.

[0158] For some possible implementations, see Figure 12 The present application also provides an electronic device 100, which includes the display panel 01 of the present application, or includes the display panel 01 produced by the method for producing a display panel of the present application. The electronic device 100 may include a device with image processing capabilities, such as a mobile phone, a desktop computer, a laptop computer, a tablet computer, a car display, a wearable device, etc. Because the electronic device 100 includes the display panel of the present application, the display effect of the electronic device 100 is better.

[0159] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
