DETAILED DESCRIPTION

[0050] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0051] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0052] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0053] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0054] In the related art, the touch layer of the display panel usually includes driving electrodes (TX) and (RX). The driving electrodes are connected to the IC (integrated circuit) through driving signal lines, and the sensing electrodes are connected to the IC through sensing signal lines. The IC sends driving signals to the driving electrodes, and the sensing electrodes receive the sent driving signals to identify touch operations. The driving electrodes and sensing electrodes are usually metal grids formed by touch conductive grids, and the metal grids forming the driving electrodes and the metal grids forming the sensing electrodes need to be separated by a break to prevent the driving electrodes and the sensing electrodes from short-circuiting. Under strong lighting conditions, since the position of the break and the position without the break have different light reflection effects, the lines formed by multiple ports can be seen more clearly, which reduces the visual effect of the display panel.

[0055] In order to solve the above problems, embodiments of the present application provide a display panel and a display device. Embodiments of the display panel and the display device are described below in conjunction with the accompanying drawings.

[0056] An embodiment of the present application provides a display panel, which may be an organic light emitting diode (OLED) display panel, or other types of display panels, such as a micro light emitting diode (Micro Light Emitting Diode, Micro-LED) or a quantum dot light emitting diode (Quantum Light Emitting Diode, QLED) display panel.

[0057] Please refer to Figure 1-Figure 3In a first aspect, the present application provides a display panel 100, wherein a display layer 10 comprises a substrate 11 and a light-emitting device layer 12 disposed on the substrate 11, and the display panel 100 comprises a display layer 10 and a touch layer 20; the touch layer 20 is disposed on one side of the display layer 10, and the touch layer 20 comprises a first touch electrode 21 and a second touch electrode 22, a plurality of first breaks 30 are disposed between the first touch electrode 21 and the second touch electrode 22, the first touch electrode 21 and the second touch electrode 22 are insulated from each other through the plurality of first breaks 30, the first touch electrode 21 comprises a plurality of first touch sub-electrodes 211 electrically connected to each other, and the second touch electrode 22 comprises a plurality of second touch sub-electrodes electrically connected to each other The touch sub-electrode 221, the first touch electrode 21 and the second touch electrode 22 are respectively provided with a plurality of second breaks 40. Of course, here, one of the first touch electrode 21 and the second touch electrode 22 may also be provided with a plurality of second breaks 40, which is not limited here. The plurality of first breaks 30 are arranged to form a first virtual pattern, and the plurality of second breaks 40 are arranged to form a second virtual pattern. The first virtual pattern is partially identical to the second virtual pattern. The partial identicalness here can be understood as the partial fragments in the first virtual pattern are the same as the partial fragments in the second virtual pattern, so that the arrangement of the second breaks on the entire screen is close to the arrangement of the first breaks, achieving a better emission effect. Preferably, the closer the second virtual pattern is to the first virtual pattern, the more consistent it is with part of the first virtual pattern.

[0058] The display layer 10 may include a substrate 11, a light-emitting device layer 12 and an encapsulation layer 13, wherein the substrate 11 may include a substrate and an array layer disposed on the substrate, and the substrate may be a hard substrate made of materials such as glass or plastic, or may be a flexible substrate made of materials such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP). A driving circuit for controlling the light-emitting device layer 12 to emit light is disposed in the array layer. The array layer is generally composed of inorganic film layers such as a metal layer, a semiconductor layer (active layer), and an insulating layer. By patterning these inorganic film layers, a driving circuit for controlling the light-emitting device layer 12 to emit light can be formed, and its specific circuit structure has a variety of implementation methods, which will not be repeated here.

[0059] The light emitting device layer 12 may include an anode, a light emitting structure, and a cathode which are sequentially arranged in a direction away from the substrate 11 , and the anode, the light emitting structure, and the cathode are sequentially stacked to form a sub-pixel.

[0060] The encapsulation layer 13 is disposed on the side of the light-emitting device layer 12 away from the substrate 11, and the encapsulation layer 13 may include an inorganic encapsulation layer 13, an organic encapsulation layer 13, and an inorganic encapsulation layer 13 stacked in sequence. The encapsulation layer 13 can protect the sub-pixels from the external environment (such as air and water), prevent air and moisture from penetrating into the display panel 100, and extend the service life and stability of quantum dots or other light-emitting materials. The encapsulation layer 13 can also prevent impurities and harmful substances from entering the display panel 100, thereby ensuring the performance and quality of the display panel 100.

[0061] The touch layer 20 is a grid-shaped metal electrode layer. One of the first touch electrode 21 and the second touch electrode 22 is a driving electrode, and the other is a sensing electrode. The sensing electrode receives the sent driving signal to identify the touch operation. The first break 30 disconnects the electrical connection between the first touch electrode 21 and the second touch electrode 22 to prevent short circuit. The first touch electrode 21 includes a plurality of first touch sub-electrodes 211 electrically connected to each other, and the second touch electrode 22 includes a plurality of second touch sub-electrodes 221 electrically connected to each other. The first touch sub-electrodes 211 and the second touch sub-electrodes 221 can be metal grids. The second break 40 will not disconnect the electrical connection between the first touch sub-electrodes 211 and the electrical connection between the second touch sub-electrodes 221. It is just a break with the same appearance as the first break 30, but has no insulation effect.

[0062] The first break 30 and the second break 40 may be evenly distributed on the display layer 10 .

[0063] It should be noted that the first virtual pattern refers to a pattern formed by connecting a plurality of first breaks 30, not a real pattern. Similarly, the second virtual pattern refers to a pattern formed by connecting a plurality of second breaks 40, not a real pattern.

[0064] The first virtual pattern and the second virtual pattern may include straight line segments, bent line segments, etc., and may also include line segments extending or bending in different directions. The first virtual pattern and the second virtual pattern may be partially the same or may have some differences.

[0065] Since the first break 30 and the second break 40 of the embodiment of the present application are evenly distributed on the display layer 10, the reflection of the first break 30 can be weakened visually, and the visibility of the texture of the touch layer 20 can be reduced, thereby improving the visual effect of the display panel 100. When the first virtual pattern and the second virtual pattern are partially the same, the difference between the first virtual pattern and the second virtual pattern is reduced, and the texture formed by the first break 30 cannot be clearly seen by the naked eye, thereby further improving the visual effect of the display panel 100.

[0066] like Figure 2As shown, in some embodiments, the first virtual pattern includes a plurality of first virtual line segments 51 disposed at intervals, and at least some of the second breaks 40 are disposed close to the first virtual line segments 51 .

[0067] The first virtual line segment 51 can be a straight line segment or a curved line segment, such as Figure 2 The first virtual line segment 51 may extend along the first direction, and a plurality of first virtual line segments 51 may be arranged at intervals along the second direction.

[0068] At least part of the second break 40 is disposed near the first virtual line segment 51 , so that the first virtual line segment 51 is not very obvious when observed with the naked eye, further improving the visual effect of the display panel 100 .

[0069] Preferably, the first virtual line segment 51 extends in a broken line shape.

[0070] It should be noted that the first virtual line segment 51 is a virtual line segment formed by connecting multiple first breaks 30, not a real line segment. The first virtual line segment 51 can be an S-shaped curve segment, or a bend segment formed by connecting straight lines extending in different directions.

[0071] like Figure 4 As shown, the first virtual line segment 51 completely separates the first touch electrode 21 from the second touch electrode 22. By extending the first virtual line segment 51 in a folded line shape, it is less likely to be seen by the user's naked eyes than a straight line, thereby improving the display effect of the display panel 100.

[0072] In some embodiments, the second virtual pattern at least includes a plurality of second virtual line segments 52 disposed at intervals.

[0073] Preferably, the second virtual line segment 52 extends in a broken line shape.

[0074] It should be noted that the second virtual line segment 52 is a virtual line segment formed by connecting a plurality of second fractures 40, and is not a real line segment. The second virtual line segment 52 may be an S-shaped curve segment, or may be a bending segment formed by connecting straight line segments extending in different directions, such as Figure 3 The dashed line segment in .

[0075] By extending the second virtual line segment 52 in a broken line shape, it is less likely to be found by the naked eye of the user compared to a straight line, thereby improving the display effect of the display panel 100 .

[0076] The second virtual line segment 52 may have the same or similar shape as the first virtual line segment 51 to further reduce the difference between the first virtual line segment 51 and the second virtual line segment 52 , blur the visual difference, and thus further enhance the visual effect of the display panel 100 .

[0077] In some embodiments, the light emitting device layer 12 includes a plurality of pixel units 121 , each pixel unit 121 includes a plurality of sub-pixels of different colors, and the orthographic projection of the sub-pixels on the substrate 11 does not overlap with the orthographic projection of the touch layer 20 on the substrate 11 .

[0078] Exemplarily, each pixel unit 121 may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel. The sub-pixels of different colors in each pixel unit 121 may be arranged in a stripe, a diamond, a PenTile, or a Delta arrangement. Among them, the Stripe arrangement is that the sub-pixels of different colors in the pixel unit 121 are arranged in a stripe shape in sequence horizontally or vertically. This arrangement is relatively simple and direct, and the manufacturing process is relatively easy. The Diamond arrangement is arranged in a rhombus or diamond shape, which can improve the pixel density to a certain extent. The PenTile arrangement is composed of sub-pixels of different sizes, usually the red and blue sub-pixels are larger, and the green sub-pixels are smaller. This method improves the brightness and energy efficiency of the screen by optimizing the layout of the sub-pixels. The sub-pixels of the Delta arrangement are arranged in a triangle, similar to the vertices of an equilateral triangle. This arrangement can improve the aperture ratio of the pixels to a certain extent and increase the brightness of the screen.

[0079] The first touch electrodes 21 and the second touch electrodes 22 in the touch layer 20 can be respectively interwoven into a grid shape by metal wires 24. “The orthographic projection of the sub-pixel on the substrate 11 does not overlap with the orthographic projection of the touch layer 20 on the substrate 11” means that the orthographic projection of the sub-pixel on the substrate 11 does not overlap with the orthographic projection of the metal wires 24 of the touch layer 20 on the substrate 11. The orthographic projection of the sub-pixel on the substrate 11 can have a certain gap with the orthographic projections of the first touch electrode 21 and the second touch electrode 22 on the substrate 11, or the orthographic projection of the sub-pixel on the substrate 11 can just touch with the orthographic projections of the first touch electrode 21 and the second touch electrode 22 on the substrate 11.

[0080] Since the orthographic projection of the sub-pixel on the substrate 11 of the embodiment of the present application does not overlap with the orthographic projection of the touch layer 20 on the substrate 11 , the metal wire 24 in the touch layer 20 will not block the sub-pixel and will not affect the light emission of the sub-pixel.

[0081] Preferably, there is a gap between the orthographic projection of the sub-pixel on the substrate 11 and the orthographic projections of the first touch sub-electrode 211 and the second touch sub-electrode 221 on the substrate 11, respectively, which can better ensure that the first touch sub-electrode 211 and the second touch sub-electrode 221 will not block the light output of the sub-pixel.

[0082] Preferably, the orthographic projections of the first touch sub-electrode 211 and / or the second touch sub-electrode 221 on the substrate 11 are arranged around the circumference of the orthographic projections of the sub-pixel on the substrate 11 .

[0083] The first touch sub-electrode 211 and the second touch sub-electrode 221 can be grids formed by metal wires 24 respectively. The sub-pixels are located in the grid holes of the first touch sub-electrode 211 and / or the second touch sub-electrode 221, which neither blocks the light output of the sub-pixels nor improves the pixel density and the touch effect of the touch layer 20.

[0084] In some embodiments, at least a portion of the first touch sub-electrodes 211 corresponding to the pixel units 121 are provided with second breaks 40 .

[0085] The second break 40 may be provided on the first touch sub-electrodes 211 corresponding to each pixel unit 121 , or may be provided on only the first touch sub-electrodes 211 corresponding to a portion of the pixel units 121 .

[0086] Each pixel unit 121 corresponds to a plurality of first touch sub-electrodes 211 , and a second break 40 may be provided at one or more first touch sub-electrodes 211 corresponding to the pixel unit 121 .

[0087] The embodiment of the present application sets the second break 40 on the first touch sub-electrodes 211 corresponding to at least part of the pixel units 121, so that the second break 40 can be dispersed on the first touch sub-electrodes 211 corresponding to different pixel units 121, thereby improving the distribution uniformity of the second break 40, thereby further improving the visual effect and display effect of the display panel 100.

[0088] Preferably, at least a portion of the second touch sub-electrodes 221 corresponding to the pixel units 121 are provided with second breaks 40 .

[0089] The second break 40 may be provided on the second touch sub-electrodes 221 corresponding to each pixel unit 121 , or may be provided on only the second touch sub-electrodes 221 corresponding to a portion of the pixel units 121 .

[0090] Each pixel unit 121 corresponds to a plurality of second touch sub-electrodes 221 , and a second break 40 may be provided at one or more corresponding second touch sub-electrodes 221 in the pixel unit 121 .

[0091] The embodiment of the present application sets the second break 40 on the second touch sub-electrodes 221 corresponding to at least part of the pixel units 121, so that the second break 40 can be dispersed on the second touch sub-electrodes 221 corresponding to different pixel units 121, thereby improving the distribution uniformity of the second break 40, thereby further improving the visual effect and display effect of the display panel 100.

[0092] In some embodiments, the second break 40 includes first sub-breaks 41 , and an orthographic projection of at least one first sub-break 41 on the substrate 11 is located within the range of an orthographic projection of the pixel unit 121 on the substrate 11 .

[0093] Exemplarily, a first sub-break 41 is disposed on at least one first touch sub-electrode 211 above the pixel unit 121 , so that at least one first sub-break 41 corresponds to the range of each pixel unit 121 .

[0094] In the embodiment of the present application, the distribution uniformity of the second breaks 40 is improved by setting the orthographic projection of at least one first sub-break 41 on the substrate 11 within the range of the orthographic projection of the pixel unit 121 on the substrate 11, thereby further improving the visual effect and display effect of the display panel 100.

[0095] Preferably, the second break 40 further includes a second sub-break 42 , and at least one second sub-break 42 is disposed between adjacent pixel units 121 .

[0096] One second sub-break 42 or a plurality of second sub-breaks 42 may be provided between adjacent pixel units 121 , thereby improving the distribution uniformity of the second breaks 40 , thereby further improving the visual effect and display effect of the display panel 100 .

[0097] Preferably, the plurality of second sub-breaks 42 are respectively located on one side of the plurality of pixel units 121 along the same direction.

[0098] Exemplarily, the second sub-breaks 42 are all located on one side of the pixel unit 121 along the vertical direction, or along one side of the horizontal direction, that is, the second sub-breaks 42 are all located on the left and right sides or the top and bottom sides of the pixel unit 121 .

[0099] In the embodiment of the present application, the plurality of second sub-breaks 42 are respectively located on one side of the plurality of pixel units 121 along the same direction, thereby ensuring that the second sub-breaks 42 do not disconnect the electrical connection between the first touch sub-electrodes 211 or the second touch sub-electrodes 221 .

[0100] Preferably, the pixel unit 121 includes a first sub-pixel 122, a second sub-pixel 123 and a third sub-pixel 124 of different colors, and the center of the first sub-pixel 122, the center of the second sub-pixel 123 and the center of the third sub-pixel 124 are arranged to form a virtual triangle.

[0101] It should be noted that the virtual triangle is not a real triangle, but a virtual shape formed by assuming that the center of the first sub-pixel 122 , the center of the second sub-pixel 123 , and the center of the third sub-pixel 124 are connected.

[0102] The sub-pixels of the pixel unit 121 of the embodiment of the present application are arranged in Delta. The sub-pixels of the Delta arrangement are arranged in a triangle, similar to the vertices of an equilateral triangle. This arrangement can improve the aperture ratio of the pixels to a certain extent and increase the brightness of the screen.

[0103] In some embodiments, the touch layer 20 includes a plurality of array units 23 , the array units 23 correspond to a plurality of pixel units 121 , the array units 23 include a plurality of first touch sub-electrodes 211 and / or a plurality of second touch sub-electrodes 221 , and the plurality of array units 23 are arranged in an array.

[0104] Exemplarily, each array unit 23 corresponds to four pixel units 121 , each pixel unit 121 includes a plurality of sub-pixels of different colors, and the plurality of array units 23 are arranged in rows and columns.

[0105] When designing the second break 40 , only the second break 40 in one array unit 23 needs to be designed, and the forms and positions of the second breaks 40 in other array units 23 can be designed according to the above, thereby improving the manufacturing efficiency of the display panel 100 .

[0106] The conductive layer accounts for a unit area of ​​the intersection between the first touch electrode 21 and the second touch electrode 22 is T1, and the conductive layer accounts for a unit area inside the first touch electrode 21 or the second touch electrode 22 is T2, where T1 is smaller than T2.

[0107] It should be noted that the “intersection position between the first touch electrode 21 and the second touch electrode 22” refers to the position where the first touch electrode 21 and the second touch electrode 22 are separated by the first break 30. The “conductive layer ratio per unit area” refers to the area ratio of the touch wire per unit area, and the touch wire includes metal wire, ITO, etc.

[0108] T1 is smaller than T2, which means that the number of the first breaks 30 is greater than the number of the second breaks 40, which is beneficial to improving the insulation effect between the first touch electrode 21 and the second touch electrode 22 and ensuring the signal transmission stability between the first touch electrode 21 and the second touch electrode 22.

[0109] like Figure 5 As shown, in some embodiments, the display panel 100 further includes a data line 60, and the orthographic projection of the data line 60 on the substrate 11 overlaps with the orthographic projection of part of the second break 40 on the substrate 11, which can reduce some unnecessary parasitic capacitance.

[0110] The data line 60 is located in the driving circuit layer of the substrate 11 and is made of metal material. The data line 60 transmits the image data signal from the driving chip to each sub-pixel. The data line 60 cooperates with the scan line. The scan line is responsible for controlling the opening and closing of the sub-pixel, and the data line 60 transmits the data signal after the scan line opens the channel of the sub-pixel. The two cooperate to realize the row-by-row or column-by-column display of the image on the display panel 100 according to a certain timing.

[0111] When the data line 60 transmits a high-frequency data signal, an electric field is generated, and if the electric field interacts with the surrounding conductors, parasitic capacitance is generated.

[0112] Parasitic capacitance is the unwanted capacitance generated by the interaction of electric fields between conductors in electronic circuits or electronic devices. In display panels, parasitic capacitance can have a negative impact on signal transmission. For example, it can cause signal delays, signal attenuation, and even interfere with the accuracy of touch signals.

[0113] After the data line 60 overlaps the second break 40, the electric field generated by the data line is "guided" or "dispersed" because the second break 40 changes the distribution and conduction path of the electric field. The existence of the second break 40 makes the distribution of the electric field lines more dispersed, which is equivalent to reducing the effective area for generating parasitic capacitance; or the electric field lines need to bypass the break, increasing the equivalent plate spacing, thereby reducing the parasitic capacitance.

[0114] Please refer to Figure 6 and Figure 7 In some embodiments, the width of the second fracture 40 is D1, and D1 satisfies: 1 μm≤D1≤10 μm.

[0115] The width D1 of the second break 40 can be any value between 1 μm and 10 μm. For example, D1 can be 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm.

[0116] If the width of the second break 40 is too small, less than 1 μm, the second break 40 may not play the role, that is, it may not blur the visual effect of the first break 30; if the width of the second break 40 is too large, greater than 10 μm, the second break 40 may be very obvious in appearance, and the second break 40 can be easily seen from the light-emitting side of the display panel 100, affecting the display effect of the display panel 100.

[0117] Therefore, in the embodiment of the present application, the visual effect and display effect of the display panel 100 can be improved by setting the width D1 of the second break 40 within a suitable range.

[0118] Preferably, the width of the insulating port is D2, and D2 satisfies: 1 μm≤D2≤10 μm.

[0119] The width D2 of the first fracture 30 may be any value between 1 μm and 10 μm. For example, D2 may be 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, or 10 μm.

[0120] If the width of the first break 30 is too small, less than 1 μm, the metal wires 24 may overlap, resulting in a short circuit between the first touch electrode 21 and the second touch electrode 22, and the first break 30 cannot play an insulating role. If the width of the first break 30 is too large, greater than 10 μm, the first break 30 may be very obvious from the appearance, and the first break 30 can be easily seen from the light-emitting side of the display panel 100, affecting the display effect of the display panel 100.

[0121] Therefore, in the embodiment of the present application, by setting the width D2 of the first break 30 within a suitable range, the visual effect and display effect of the display panel 100 can be improved, and the insulation effect of the first break 30 on the first touch electrode 21 and the second touch electrode 22 can be ensured.

[0122] like Figure 6 As shown, in some embodiments, a second break 40 is provided between two adjacent first touch sub-electrodes 211 , and a second break 40 is provided between two adjacent second touch sub-electrodes 221 .

[0123] The first touch electrode 21 can be a metal grid, and each first touch sub-electrode 211 is a metal grid. A second break 40 is set between two adjacent first touch sub-electrodes 211. That is to say, a second break 40 is set on the metal wire 24 segment shared by the metal grids of adjacent first touch sub-electrodes 211, so that adjacent first touch sub-electrodes 211 share this second break 40.

[0124] Similarly, the second touch electrode 22 can be a metal grid, each second touch sub-electrode 221 is a metal lattice, and a second break 40 is set between two adjacent second touch sub-electrodes 221. That is to say, a second break 40 is set on the metal wire 24 segment shared by the metal lattices of adjacent second touch sub-electrodes 221, so that adjacent second touch sub-electrodes 221 share this second break 40.

[0125] The embodiment of the present application sets a second break 40 between two adjacent first touch sub-electrodes 211 and sets a second break 40 between two adjacent second touch sub-electrodes 221, thereby increasing the distribution uniformity of the second break 40, so that when observed with the naked eye from the light-emitting side of the display panel 100, there are no obvious lines, thereby further improving the visual effect of the display panel 100.

[0126] Please refer to Figure 8 and Fig. 9 In some embodiments, the first fracture 30 and the second fracture 40 each include two end surfaces 43 disposed opposite to each other, and the two end surfaces 43 are disposed at an inclination.

[0127] The first touch sub-electrode 211 and the second touch sub-electrode 221 each include a plurality of metal wires 24 . Each virtual segment includes two oppositely disposed end surfaces 43 . The end surface 43 of the second segment 40 is inclined relative to the metal wires 24 .

[0128] That is to say, the second fracture 40 is an inclined fracture, and the second fracture 40 which is vertical relative to the end surface 43 has lower visibility, thereby improving the visual effect and display effect of the display panel 100 .

[0129] Preferably, the end surface 43 of each first break 30 or second break 40 has an inclination direction different from the end surface 43 of the first break 30 or second break 40 adjacent thereto.

[0130] For example, the inclination direction of the end face 43 of a second break 40 is exactly opposite to the inclination direction of the end face 43 of the adjacent or surrounding second break 40 .

[0131] In the embodiment of the present application, the end surface 43 of each second break 40 is tilted in a different direction from the end surface 43 of the second break 40 adjacent thereto, thereby further reducing the visual visibility of the second break 40 .

[0132] like Fig.10 As shown, in some embodiments, the display panel 100 further includes a light shielding layer 70 , and the orthographic projection of the first break 30 and / or the second break 40 on the substrate 11 at least partially overlaps with the orthographic projection of the light shielding layer 70 on the substrate 11 .

[0133] The light shielding layer 70 can be made of black organic material in the form of a black matrix. The light shielding layer 70 is provided with openings for the light of the sub-pixels to pass through, and the light shielding layer 70 has a high absorption rate for visible light. The contrast of the display panel 100 can be improved, and the light crosstalk between adjacent pixels can be reduced.

[0134] In the embodiment of the present application, the first break 30 and / or the second break 40 is overlapped with the projection of the light-shielding layer 70 on the substrate 11. The light-shielding layer 70 absorbs part of the ambient light, thereby reducing the reflection of the first break 30 and / or the second break 40, thereby improving the display effect of the display panel 100.

[0135] In some embodiments, the light shielding layer 70 is disposed on a side of the touch layer 20 facing away from the substrate 11 .

[0136] That is to say, the light shielding layer 70 is disposed above the touch layer 20 , and can better absorb external ambient light, thereby improving the effect of reducing reflection on the first break 30 and / or the second break 40 .

[0137] like Fig.11 As shown, in some other embodiments, the display panel 100 further includes an encapsulation layer 13 , and the light-emitting device layer 12 , the encapsulation layer 13 , the light-shielding layer 70 and the touch control layer 20 are sequentially arranged in a direction away from the substrate 11 .

[0138] The light shielding layer 70 is disposed below the touch layer 20 and between the encapsulation layer 13 and the touch layer 20. The light shielding layer 70 can also absorb part of the ambient light, thereby reducing the reflection of the first break 30 and / or the second break 40.

[0139] like Fig.12 As shown, in some embodiments, the touch layer 20 further includes a virtual electrode 25 , and the virtual electrode 25 is disposed between the first touch electrode 21 and the second touch electrode 22 .

[0140] The dummy electrode 25 is an electrode not connected to an electrical signal, and its shape and structure may be the same or similar to the first touch electrode 21 and the second touch electrode 22 , except that it has no electrical connection.

[0141] The virtual electrode 25 is equivalent to adding an extra electrode sheet between the first touch electrode 21 and the second touch electrode 22, and converting the original one inductive capacitor into multiple inductive capacitors. These inductive capacitors can be connected in series, in parallel, or in series-parallel. Their existence is equivalent to reducing the distance between the electrodes, changing the local electric field strength, causing the redistribution of charge, so that more areas can respond sensitively to the user's touch, thereby increasing the touch area and improving the touch sensitivity. In addition, the more virtual electrodes 25 there are, the higher the touch sensitivity.

[0142] The virtual electrode 25 can make the electric field distribution between the first touch electrode 21 and the second touch electrode 22 more uniform. Without the virtual electrode 25, the electric field may be concentrated in certain areas, resulting in the accuracy and sensitivity of touch detection being affected. The addition of the virtual electrode 25 can adjust the electric field distribution, making the electric field in the entire touch area more stable and uniform, and improving the consistency and accuracy of touch.

[0143] The first touch electrodes 21 and the second touch electrodes 22 may have signal crosstalk, which affects the accuracy of the touch signal. The virtual electrodes 25 can play a role of shielding and isolation, reduce the signal crosstalk between the driving electrodes and the sensing electrodes, improve the signal-to-noise ratio of the touch signal, and thus improve the accuracy of touch detection.

[0144] In the embodiment of the present application, the virtual electrode 25 is provided between the first touch electrode 21 and the second touch electrode 22 to improve the touch sensitivity, improve the uniformity of the electric field distribution, and reduce signal interference.

[0145] Preferably, the virtual electrode 25 is provided with a plurality of second breaks 40 .

[0146] In the embodiment of the present application, by providing a plurality of second breaks 40 on the virtual electrode 25 , the distribution uniformity of the second breaks 40 in the entire display panel 100 can be further improved, thereby further improving the visual effect and display effect of the display panel 100 .

[0147] like Fig.13 As shown, in the second aspect, the embodiment of the present application further provides a display panel 100, including a display layer 10, a touch layer 20 and a shading layer 70, the display layer 10 includes a substrate 11 and a light-emitting device layer 12 arranged on the substrate; the touch layer 70 is arranged on the side of the light-emitting device layer 12 away from the substrate 11, the touch layer 70 includes a first touch electrode 21 and a second touch electrode 22, a plurality of first breaks 30 are arranged between the first touch electrode 21 and the second touch electrode 22, the first touch electrode 21 and the second touch electrode 22 are insulated from each other by the plurality of first breaks 30, the first touch electrode 21 includes a plurality of first touch sub-electrodes 211 electrically connected to each other, and the second touch electrode 22 includes a plurality of second touch sub-electrodes 221 electrically connected to each other; the shading layer 70 is arranged on the side of the light-emitting device layer 12 away from the substrate 11, and the first break 30 and the orthographic projection of the shading layer 70 on the substrate 11 at least partially overlap with the orthographic projection of the shading layer 70 on the substrate 11.

[0148] In the embodiment of the present application, the projections of the first break 30 and the light shielding layer 70 on the substrate 11 are overlapped, and the light shielding layer 70 absorbs part of the ambient light, so that the reflection of the first break 30 can be reduced, thereby improving the display effect of the display panel 100.

[0149] In some embodiments, the light shielding layer 70 is disposed on a side of the touch layer 20 facing away from the substrate 11 .

[0150] That is to say, the light shielding layer 70 is disposed above the touch layer 20 , and can better absorb external ambient light, thereby improving the effect of reducing reflection on the first break 30 .

[0151] like Fig.14As shown, in some other embodiments, the display panel 100 further includes an encapsulation layer 13 , and the light-emitting device layer 12 , the encapsulation layer 13 , the light-shielding layer 70 and the touch control layer 20 are sequentially arranged in a direction away from the substrate 11 .

[0152] The light shielding layer 70 is disposed below the touch layer 20 and between the encapsulation layer 13 and the touch layer 20 . The light shielding layer 70 can also absorb part of the ambient light, thereby reducing the reflection of the first break 30 .

[0153] like Fig.15 As shown, in the third aspect, an embodiment of the present application further provides a mask plate 90, which is applied to the display panel 100 of any of the above-mentioned embodiments, and the mask plate 90 includes a shading area 91 and a light-transmitting area 92, and one of the shading area 91 and the light-transmitting area 92 corresponds to the first break 30 and the second break 40.

[0154] The mask 90 is like a "template" that controls the transmission and blocking of light to achieve graphical processing of the various layers of the display panel 100. For example, in the photolithography process, the specific pattern of the light-transmitting area 92 and the light-shielding area 91 on the mask 90 is used to allow the exposure light source such as ultraviolet light to be transmitted through the light-transmitting area 92 to irradiate the photoresist below, and the part of the photoresist that is irradiated with light and the part that is not irradiated with light will produce different chemical reactions, and then after subsequent development and other processes, the desired graphic structure can be formed on the substrate and other materials of the display panel.

[0155] The shading area 91 mainly blocks light and is generally made of opaque materials or processed by special processes to have shading properties. When manufacturing a display panel, when light is irradiated onto the mask 90, the shading area 91 can ensure that the corresponding area below will not be exposed. The light-transmitting area 92 is an area that allows light to pass smoothly. During the photolithography process, the light-transmitting area allows the exposure light source to reach the photoresist and other materials below, triggering corresponding chemical changes, thereby achieving the transfer of the pattern.

[0156] One of the light-shielding area 91 and the light-transmitting area 92 corresponds to the first break 30 and the second break 40 . Specifically, whether the light-shielding area 91 or the light-transmitting area 92 corresponds to the first break 30 and the second break 40 needs to be selected according to the material of the photoresist.

[0157] It should be noted that “one of the shading area 91 and the light-transmitting area 92 corresponds to the first break 30 and the second break 40 ” means: when preparing the touch layer 20 , one of the shading area 91 and the light-transmitting area 92 is located directly above the first break 30 and the second break 40 , and one of the shading area 91 and the light-transmitting area 92 is aligned with the first break 30 and the second break 40 .

[0158] In the embodiment of the present application, a mask plate 90 is used to prepare the touch layer 70 , and patterning of the touch layer 70 is achieved to obtain the touch layer 70 having the first fracture 30 and the second fracture 40 .

[0159] In some embodiments, the touch layer 70 is patterned using positive photoresist, and the light-transmitting area 91 of the mask 90 corresponds to the first break 30 and the second break 40; or, if the touch layer 70 is patterned using negative photoresist, the light-shielding area of ​​the mask 90 corresponds to the first break 30 and the second break 40.

[0160] Photoresists are generally divided into two categories: positive photoresists and negative photoresists, which have different photosensitivity properties and imaging principles.

[0161] After being exposed to light, the properties of the exposed area of ​​the positive photoresist will change, making it easier to be removed by the developer. For example, in the photolithography process, when ultraviolet light is irradiated onto the positive photoresist through the light-transmitting area of ​​the mask 90, the illuminated portion will be dissolved in the subsequent development process, while the unexposed portion will be retained, thereby achieving the transfer of the pattern. The properties of the negative photoresist are opposite to those of the positive photoresist. After being exposed to light, the photoresist in the exposed area will undergo cross-linking and other reactions, making this part more difficult to be removed by the developer and eventually retained, while the unexposed area will be washed away by the developer.

[0162] When the touch layer 70 is patterned using positive photoresist, the light-transmitting area 92 of the mask 90 corresponds to the first break 30 and the second break 40. This is because during the photolithography process, light needs to be transmitted through the light-transmitting area 92 to irradiate the positive photoresist, so that the photoresist in the corresponding area changes. After subsequent development and other processes, these illuminated areas (that is, the positions corresponding to the light-transmitting area 92 of the mask 91) are removed, thereby forming the first break 30 and the second break 40 at this position.

[0163] If the touch layer 70 is patterned using negative photoresist, the light shielding area 91 of the mask 90 corresponds to the first break 30 and the second break 40. Because for negative photoresist, the area not illuminated will be removed, so the light shielding area 91 of the mask 91 is needed to block the light, so that the negative photoresist portion corresponding to the light shielding area 91 is removed after development, thereby forming the first break 30 and the second break 40 at this position.

[0164] In a fourth aspect, an embodiment of the present application further provides a display device, comprising a display panel 100 according to any of the above embodiments.

[0165] The display device may be any device with a display function, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. It may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or an automated machine.

[0166] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
