Description
Technical Field
[0001] The present application relates to the field of display technologies, and particularly to a display panel and a display device. Background Art
[0002] OLED (Organic Light Emitting Diode) display panels have many advantages such as being all-solid-state, actively emitting light, having a fast response speed, a high contrast ratio, no viewing angle limitation, and being capable of realizing flexible display. It is a new type of display technology developed in the mid-20th century and is widely used in people's daily production and life.
[0003] In related technologies, a display panel includes a substrate and touch traces. The touch traces are disposed on one side of the substrate for realizing touch functions. However, the display effect of the above display panel needs to be improved. Summary of the Invention
[0004] Based on this, it is necessary to provide a display panel and a display device, aiming to improve the display effect of the display panel.
[0005] In a first aspect, an embodiment of the present application provides a display panel, including a substrate, a plurality of light-emitting units, and touch traces. The plurality of light-emitting units and the touch traces are both disposed on one side of the substrate; the plurality of light-emitting units include a plurality of first light-emitting units, and the light-emitting colors of the plurality of first light-emitting units are the same; the touch traces enclose to form a plurality of openings, and the plurality of openings and the plurality of light-emitting units are correspondingly arranged. The orthographic projection of the light-emitting unit on the substrate is located within the orthographic projection of the corresponding opening on the substrate; wherein, the opening corresponding to the first light-emitting unit is a first opening, the touch traces located on the outer periphery of the same first opening are first sub-touch traces, and a first break and a second break are provided on the first sub-touch traces. The extension center line of the first break and the extension center line of the second break intersect within the first opening.
[0006] In the display panel provided by the embodiment of the present application, since the extension center lines of the first break and the second break are different in the extension direction and intersect within the first opening, the extension center lines of the first break and the second break form an L shape. At the same viewing angle, the first break and the second break cannot be visible simultaneously, reducing the total extension length of the first break group formed by the first break and the second break along the same viewing angle, thereby reducing the observability of bright and dark stripes, and further improving the display effect of the display panel.
[0007] In a second aspect, an embodiment of the present application further provides a display device, and the display device includes the display panel provided in the first aspect.
[0008] The display device provided by the embodiment of the present application includes a display panel. By making the extension center lines of the first break and the second break different in the extension direction and intersecting within the first opening, the extension center lines of the first break and the second break form an L shape. At the same viewing angle, the first break and the second break cannot be visible simultaneously, reducing the total extension length of the first break group formed by the first break and the second break along the same viewing angle, thereby reducing the observability of the bright and dark stripes and further improving the display effect of the display panel.

Detailed implementation manners
[0019] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant accompanying drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present application more thorough and comprehensive.
[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0021] When describing the positional relationship, unless otherwise specified, when an element such as a layer, film or substrate is referred to as being "on" another element, it can be directly on the other element or there can also be intermediate elements. Further, when a layer is referred to as being "under" another layer, it can be directly below or there can be one or more intermediate elements. It can also be understood that when a layer is referred to as being "between" two layers, it can be the only layer between the two layers or there can also be one or more intermediate elements.
[0022] In the case of using "including", "having", and "comprising" described herein, unless an explicit limiting term is used, such as "only", "consisting of", etc., another component can also be added. Unless otherwise mentioned, terms in the singular form can include the plural form and should not be understood as having a quantity of one.
[0023] It should be understood that although terms such as "first" and "second" may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element.
[0024] It should also be understood that when interpreting an element, although not explicitly described, the element is interpreted as including an error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximately" or "substantially" may mean within one or more standard deviations, which is not defined herein.
[0025] In addition, in the specification, the phrase "schematic diagram of planar distribution" refers to the accompanying drawing when observing the target part from above, and the phrase "schematic cross-sectional view" refers to the accompanying drawing when observing the cross-section intercepted by vertically cutting the target part from the side.
[0026] In addition, the accompanying drawings are not drawn to a 1:1 scale, and the relative sizes of the various elements are only drawn by way of example in the accompanying drawings and not necessarily to the true scale.
[0027] As described in the background art section, in the related art, the display panel includes a substrate and touch traces. The touch traces are disposed on one side of the substrate, and a plurality of breaks are provided on the touch traces. The plurality of breaks form a break group in the row direction, and there are a plurality of break groups, and the plurality of break groups are arranged at intervals in the column direction.
[0028] However, the plurality of breaks in the same break group as a whole present a straight line shape or a wavy shape, so that the plurality of breaks in the same break group as a whole present a certain regularity in the row direction, resulting in regular breaks in the touch traces. When the display panel is not lit, the reflection difference between the non-break part and the break part of the touch traces will cause bright and dark stripes on the display panel. In addition, when the display panel is lit, the light leakage difference between the non-break part and the break part of the touch traces will also cause bright and dark stripes on the display panel, thereby affecting the display effect of the display panel.
[0029] Based on the above technical problems, the inventors have found through research that by making the extension directions of the extension centerlines of the first break and the second break different and intersecting within the first opening, so that the extension centerlines of the first break and the second break form an L shape, and at the same viewing angle, the first break and the second break cannot be seen simultaneously, reducing the total extension length of the first break group formed by the first break and the second break along the same viewing angle, thereby reducing the observability of the bright and dark stripes, and further improving the display effect of the display panel.
[0030] The above is the core idea of this application. Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.
[0031] The following is combined with the attached Figure 1-8 The display panel 100 and the display device provided in the embodiments of this application will be described.
[0032] This embodiment provides a display device, and the display device may include the display panel 100 in any of the following embodiments. Therefore, the display device also has the beneficial effects of the display panel 100 in the following embodiments. For the same parts, reference may be made to the explanation of the display panel 100 below, and details will not be repeated here.
[0033] In some embodiments, the display device may be a mobile phone or any electronic product with a display function, including but not limited to the following categories: television, laptop computer, desktop monitor, tablet computer, digital camera, smart bracelet, smart glasses, in-vehicle display, industrial control equipment, medical display screen, touch interaction terminal, etc. The embodiments of this application do not make special limitations on this.
[0034] In some embodiments, the display panel 100 may include an organic light-emitting diode display panel (Organic Light Emitting Diode, abbreviated as OLED), a quantum dot light-emitting diode display panel (Quantum Dot Light Emitting Diodes, abbreviated as QLED), a mini light-emitting diode display (Mini Light Emitting Diode Display, abbreviated as Mini LED), or a micro light-emitting diode display (Micro Light Emitting Diode Display, abbreviated as Micro LED), etc. In the embodiments of this application, the display panel 100 is taken as an OLED display panel as an example for description.
[0035] The following describes the display panel 100 provided in the embodiments of this application.
[0036] See Figure 1 And Figure 8, the display panel 100 may have a first direction X, a second direction Y, and a third direction Z, and the first direction X, the second direction Y, and the third direction Z are all different. The first direction X and the second direction Y may be any two different directions parallel to the display panel 100, and the third direction Z may be any direction intersecting the plane parallel to the display panel 100. For example, the first direction X, the second direction Y, and the third direction Z may be perpendicular to each other pairwise. Exemplarily, the first direction X may be the length direction of the display panel 100, the second direction Y may be the width direction of the display panel 100, and the third direction Z may be the thickness direction of the display panel 100. The length, width, thickness, etc. in the embodiments of the present application are only for convenience of description and do not imply any limitation on the size. For example, the width may be greater than, equal to, or less than the length.
[0037] See Figure 8 , the display panel 100 may include a substrate 110 and touch traces 160 located on one side of the substrate 110, and the substrate 110 may provide support for the remaining structural layers to be subsequently provided.
[0038] See Figure 1 and Figure 8 , the display panel 100 may include a plurality of light-emitting units 120, and the plurality of light-emitting units 120 are arranged on one side of the substrate 110. The plurality of light-emitting units 120 may include a plurality of first light-emitting units 121, and the plurality of first light-emitting units 121 have the same light-emitting color. For example, the touch traces 160 may be disposed on the side of the light-emitting units 120 facing away from the substrate 110. The touch traces 160 may be used to implement a touch function.
[0039] Among them, the touch traces 160 may enclose a plurality of openings 130, and the plurality of openings 130 and the plurality of light-emitting units 120 are correspondingly arranged, and the orthographic projection of the light-emitting units 120 on the substrate 110 is located within the orthographic projection of the corresponding openings 130 on the substrate 110. Since the touch traces 160 enclose a plurality of openings 130, and the orthographic projection of the light-emitting units 120 on the substrate 110 is located within the orthographic projection of the corresponding openings 130 on the substrate 110, the light shielding of the touch traces 160 on the light-emitting units 120 can be reduced.
[0040] See Figure 1 and Figure 8, the opening 130 corresponding to the first light-emitting unit 121 is the first opening 131, and the touch trace 160 located on the outer periphery of the same first opening 131 is the first sub-touch trace 161. The first sub-touch trace 161 is provided with a first break 141 and a second break 142. The extension center line of the first break 141 (i.e., the first extension center line S1) and the extension center line of the second break 142 (i.e., the second extension center line S2) intersect within the first opening 131. Among them, the first break 141 and the second break 142 on the same first sub-touch trace 161 together form a first break group. In this way, the first extension center line S1 and the second extension center line S2 are different in direction, and the two intersect in an L shape within the first opening 131. This design makes it impossible for the first break 141 and the second break 142 to be visible simultaneously from the same viewing angle, reducing the total extension length of the first break group formed by the first break 141 and the second break 142 along the same viewing angle, reducing the observability of bright and dark stripes, and thus significantly improving the optical visual effect of the display panel 100. In addition, the first break 141 and the second break 142 can ensure the corresponding wire break requirements inside the normal touch function of the touch trace 160. Secondly, by making each first extension center line S1 and the corresponding second extension center line S2 intersect in an L shape within the corresponding first opening 131, the light-emitting colors of the light-emitting units 120 corresponding to each first opening 131 are the same, which can reduce the setting density of virtual electrodes and improve the touch accuracy of the display panel 100.
[0041] Among them, in the embodiments of the present application, the corresponding setting of A and B may mean: one A is correspondingly set with at least one B, or one B is correspondingly set with at least one A. The embodiments of the present application are described by taking the corresponding setting of one A and one B as an example. For example, the corresponding setting of the light-emitting unit 120 and the opening 130 may mean that one light-emitting unit 120 is correspondingly set with at least one opening 130, or one opening 130 is correspondingly set with at least one light-emitting unit 120. The embodiments of the present application are described by taking the corresponding setting of one opening 130 and one light-emitting unit 120 as an example.
[0042] The following details the settings of the first break 141 and the second break 142 provided in the embodiments of the present application.
[0043] In some embodiments, refer to Figure 1, in the same first sub-touch trace 161, the first sub-touch trace 161 includes a plurality of extension segments 164, and the extension directions of two adjacent extension segments 164 intersect. Exemplarily, the first sub-touch trace 161 may be a polygon. For example, the first sub-touch trace 161 may be an N-sided polygon, and the number of extension segments 164 of the first sub-touch trace 161 is N. The first break 141 and the second break 142 are provided on different extension segments 164, and the extension direction of the extension segment 164 where the first break 141 is located intersects with the extension direction of the extension segment 164 where the second break 142 is located. In this way, it can be simply achieved that the first extension center line S1 and the second extension center line S2 intersect within the first opening 131.
[0044] It should be noted that, in the extension segment 164 where the first break 141 is provided and the first break 141, along the direction perpendicular to the extension direction of the extension segment 164, the first break 141 includes a first end and a second end, and the first extension center line S1 may pass through the centers of the first end and the second end. Other breaks and corresponding extension center lines in the embodiments of the present application are similar and will not be elaborated herein.
[0045] In some embodiments, refer to Figure 1 , in at least some adjacent first sub-touch traces 161, the extension segment 164 where the first break 141 of one of the first sub-touch traces 161 is located is different from the extension segment 164 where the first break 141 of the other first sub-touch trace 161 is located. In this way, in these two adjacent first sub-touch traces 161, the different extension segments 164 where the first breaks 141 are located can break the regular arrangement of the first breaks 141 of these two adjacent first sub-touch traces 161, so that the first break groups of these two adjacent first sub-touch traces 161 are arranged disorderly in a short period, and alleviate the bright and dark stripes caused by the regular arrangement of the first break groups in a long period.
[0046] In some embodiments, refer to Figure 1 , in at least some adjacent first sub-touch traces 161, the extension segment 164 where the second break 142 of one of the first sub-touch traces 161 is located is different from the extension segment 164 where the second break 142 of the other first sub-touch trace 161 is located. In this way, in these two adjacent first sub-touch traces 161, the different extension segments 164 where the second breaks 142 are located can break the regular arrangement of the second breaks 142 of these two adjacent first sub-touch traces 161, so that the first break groups of these two adjacent first sub-touch traces 161 are arranged disorderly in a short period, and alleviate the bright and dark stripes caused by the regular arrangement of the first break groups in a long period.
[0047] In some embodiments, refer to Figure 2, in the same first sub-touch trace 161, the multiple extension segments 164 include a first extension segment 1641, a second extension segment 1642, and a third extension segment 1643. The extension direction of the first extension segment 1641 is the same as that of the third extension segment 1643, and the extension direction of the first extension segment 1641 intersects with that of the second extension segment 1642. The first extension segment 1641 and the third extension segment 1643 are opposite and spaced apart, and one end of the first extension segment 1641 and one end of the third extension segment 1643 can be connected by the second extension segment 1642.
[0048] In some embodiments, in the same first sub-touch trace 161, the multiple extension segments 164 include a fourth extension segment 1644. The extension direction of the fourth extension segment 1644 is the same as that of the second extension segment 1642. The fourth extension segment 1644 and the second extension segment 1642 are opposite and spaced apart. The other end of the first extension segment 1641 and the other end of the third extension segment 1643 can be connected by the fourth extension segment 1644. Wherein, the positions of the first extension segment 1641 and the third extension segment 1643 can be interchanged. The positions of the fourth extension segment 1644 and the second extension segment 1642 can be interchanged.
[0049] Exemplarily, in the same first sub-touch trace 161, the first break 141 can be provided in one of the first extension segment 1641 and the third extension segment 1643, and the second break 142 can be provided in one of the second extension segment 1642 and the fourth extension segment 1644.
[0050] In some embodiments, referring to Figure 2 and Figure 3 , in at least some adjacent two first sub-touch traces 161, the first break 141 in one of the first sub-touch traces 161 is located in the first extension segment 1641, and the second break 142 in this one of the first sub-touch traces 161 is located in the second extension segment 1642. The first break 141 in the other first sub-touch trace 161 is located in the third extension segment 1643, and the second break 142 in the other first sub-touch trace 161 is located in the second extension segment 1642. Thus, in the two adjacent first sub-touch traces 161, the extension segments 164 where the first breaks 141 are located are different, which can break the regular arrangement of the first breaks 141 in the two adjacent first sub-touch traces 161, making the first break groups in the two adjacent first sub-touch traces 161 arranged disorderly in a short period, and alleviating the bright and dark stripes caused by the regular arrangement of the first break groups in a long period. Additionally, in the two adjacent first sub-touch traces 161, the extension segments 164 where the second breaks 142 are located are the same, which is beneficial to reducing the design difficulty of the second breaks 142.
[0051] In some embodiments, referring to Figure 2 andFigure 4 , among at least partially adjacent two first sub-touch traces 161, a first break 141 in one of the first sub-touch traces 161 is located in a first extension segment 1641, and a second break 142 in this one of the first sub-touch traces 161 is located in a second extension segment 1642. A first break 141 in the other first sub-touch trace 161 is located in a third extension segment 1643, and a second break 142 in the other first sub-touch trace 161 is located in a fourth extension segment 1644. In this way, among the adjacent two first sub-touch traces 161, the extension segments 164 where the first break 141 is located are different, and the extension segments 164 where the second break 142 is located are different, which can simultaneously break the regular arrangement of the first break 141 and the second break 142 of the adjacent two first sub-touch traces 161, so that the first break groups of the adjacent two first sub-touch traces 161 are arranged disorderly in a short period, and better alleviate the bright and dark stripes caused by the regular arrangement of the first break group in a long period. Among them, see Figure 6 , the first break groups of multiple first sub-touch traces 161 are arranged disorderly in a short period, so that the visibility of the first break groups of the multiple first sub-touch traces 161 is reduced.
[0052] In some embodiments, see Figure 7 , the display panel 100 may include multiple first regions 100a, the multiple first regions 100a may be arranged in an array, and the touch traces 160 are disposed in the multiple first regions 100a. For example, the multiple first regions 100a may be arranged in an array along a first direction X and a second direction Y. In the same first region 100a, the touch trace 160 may include multiple first sub-touch traces 161, the first breaks 141 of at least partially adjacent two first sub-touch traces 161 are located on different extension segments 164, and / or the second breaks 142 of at least partially adjacent two first sub-touch traces 161 are located on different extension segments 164, so that the first break groups of the adjacent two first sub-touch traces 161 are arranged disorderly in the first region 100a to alleviate the bright and dark stripes caused by the regular arrangement of the first break group in a long period. The patterns of the touch traces 160 in different first regions 100a may be the same, and there is no need to separately design the patterns of the touch traces 160 in different first regions 100a, so that the design difficulty of the touch traces 160 can be reduced on the premise of alleviating the bright and dark stripes of the display panel 100.
[0053] The following details the settings of other breaks provided in the embodiments of the present application.
[0054] In some embodiments, see Figure 5, a plurality of light-emitting units 120 include at least one second light-emitting unit 122, and at least one second light-emitting unit 122 is correspondingly arranged with at least one first light-emitting unit 121. The light-emitting color of the second light-emitting unit 122 is the same as that of the first light-emitting unit 121. Among them, the opening 130 corresponding to the second light-emitting unit 122 is the second opening 132, the touch trace 160 located on the outer periphery of the second opening 132 is the second sub-touch trace 162, a third break 143 is provided on the second sub-touch trace 162, the third break 143 is arranged on the side of the second sub-touch trace 162 close to the first sub-touch trace 161, and the extended center line of the third break 143 (i.e., the third extended center line S3) is collinearly arranged with the first extended center line S1 of the corresponding first sub-touch trace 161. In this way, the extended center line formed by the first extended center line S1 and the third extended center line S3 intersects the second extended center line S2 in an L shape within the first opening 131. This design makes it impossible for the second break 142 to be visible simultaneously with the first break 141 and the third break 143 from the same viewing angle, reducing the observability of the bright and dark stripes, thereby significantly improving the optical visual effect of the display panel 100.
[0055] In some embodiments, refer to Figure 5 , the touch trace 160 includes a fifth extension section 1645, the fifth extension section 1645 is located between the first sub-touch trace 161 and the corresponding second sub-touch trace 162, and openings 130 are provided between the fifth extension section 1645 and the corresponding first sub-touch trace 161, and between the fifth extension section 1645 and the corresponding second sub-touch trace 162. That is, two openings 130 are provided between the first opening 131 and the corresponding second opening 132. A fifth break 145 is provided on the fifth extension section 1645, and the extended center line of the fifth break 145 (i.e., the fifth extended center line S5) is collinearly arranged with the first extended center line S1 of the corresponding first sub-touch trace 161. In this way, the first extended center line S1, the third extended center line S3, and the fifth extended center line S5 are collinearly arranged, and the extended center line formed by the first extended center line S1, the third extended center line S3, and the fifth extended center line S5 intersects the second extended center line S2 in an L shape within the first opening 131. This design makes it impossible for the second break 142 to be visible simultaneously with the first break 141, the third break 143, and the fifth break 145 from the same viewing angle, reducing the observability of the bright and dark stripes, thereby significantly improving the optical visual effect of the display panel 100. In addition, the first break 141, the third break 143, and the fifth break 145 together form a second break group, and the broken line area of the second break group is relatively long, which is beneficial to ensuring the corresponding broken line requirements inside the normal touch function of the touch trace 160.
[0056] Among them, the arrangement density of the second set of fracture points can be relatively small, and the arrangement density of the second set of fracture points can be less than that of the first set of fracture points.
[0057] In some embodiments, referring to Figure 5 , a plurality of light-emitting units 120 include at least one third light-emitting unit 123. At least one third light-emitting unit 123 is correspondingly arranged with at least one second light-emitting unit 122, and the light-emitting color of the third light-emitting unit 123 is the same as that of the first light-emitting unit 121. Among them, the opening 130 corresponding to the third light-emitting unit 123 is the third opening 133, the touch trace 160 located on the outer periphery of the third opening 133 is the third sub-touch trace 163, and a fourth fracture point 144 is provided on the third sub-touch trace 163. The fourth fracture point 144 is arranged on the side of the third sub-touch trace 163 close to the first sub-touch trace 161, and the extension center line of the fourth fracture point 144 (i.e., the fourth extension center line S4) is collinearly arranged with the second extension center line S2 of the corresponding first sub-touch trace 161. In this way, the extension center line formed by the second extension center line S2 and the fourth extension center line S4 intersects with the first extension center line S1 in an L shape within the first opening 131. This design enables the first fracture point 141 not to be visible simultaneously with the second fracture point 142 and the fourth fracture point 144 from the same viewing angle, reducing the observability of bright and dark stripes, and thus significantly improving the optical visual effect of the display panel 100.
[0058] In some embodiments, referring to Figure 5, the touch trace 160 includes a sixth extension segment 1646. The sixth extension segment 1646 is located between the first sub-touch trace 161 and the corresponding third sub-touch trace 163. Openings 130 are provided between the sixth extension segment 1646 and the corresponding first sub-touch trace 161, and between the sixth extension segment 1646 and the corresponding third sub-touch trace 163. That is, two openings 130 are provided between the first opening 131 and the corresponding third opening 133. A sixth break 146 is provided on the sixth extension segment 1646. The extension center line of the sixth break 146 (i.e., the sixth extension center line S6) is collinear with the second extension center line S2 of the corresponding first sub-touch trace 161. In this way, the second extension center line S2, the fourth extension center line S4, and the sixth extension center line S6 are collinear. The extension center line formed by the second extension center line S2, the fourth extension center line S4, and the sixth extension center line S6 intersects the first extension center line S1 in an L shape within the first opening 131. This design makes it impossible for the first break 141 to be visible simultaneously with the second break 142, the fourth break 144, and the sixth break 146 from the same viewing angle, reducing the observability of the bright and dark stripes, thereby significantly improving the optical visual effect of the display panel 100. In addition, the second break 142, the fourth break 144, and the sixth break 146 can jointly form a third break group. The broken line area of the third break group is relatively long, which is beneficial to ensuring the corresponding broken line requirements inside the normal touch function of the touch trace 160.
[0059] Among them, the arrangement density of the third break group can be relatively small, and the arrangement density of the third break group can be less than the arrangement density of the first break group.
[0060] In some embodiments, refer to Figure 5 , the multiple openings 130 include a fourth opening 134 and a fifth opening 135. The light-emitting colors of the light-emitting units 120 corresponding to the fourth opening 134 and the fifth opening 135 are different, and the light-emitting colors of the light-emitting units 120 corresponding to the fourth opening 134 and the fifth opening 135 are both different from the light-emitting color of the first light-emitting unit 121. That is, the light-emitting colors of any two of the light-emitting unit 120 corresponding to the fourth opening 134, the light-emitting unit 120 corresponding to the fifth opening 135, and the first light-emitting unit 121 are different. The fourth opening 134 is located between the fifth extension segment 1645 and the corresponding first sub-touch trace 161, and the fifth opening 135 is located between the fifth extension segment 1645 and the corresponding second sub-touch trace 162. In this way, among the multiple light-emitting units 120 corresponding to the touch trace 160 where the second break group is located, the light-emitting colors of any two adjacent light-emitting units 120 are different. When lighting the light-emitting units 120 of the same color, it is beneficial to reduce the bright and dark stripes caused by the second break group.
[0061] In some embodiments, the fourth opening 134 is also located between the sixth extension segment 1646 and the corresponding third sub-touch trace 163, and the fifth opening 135 is also located between the sixth extension segment 1646 and the corresponding first sub-touch trace 161. Thus, among the multiple light-emitting units 120 corresponding to the touch trace 160 where the third break group is located, the light-emitting colors of any two adjacent light-emitting units 120 are different. When lighting the light-emitting units 120 of the same color, it is beneficial to reduce the bright and dark stripes caused by the third break group.
[0062] Exemplarily, on the extension segment 164 provided with the first break 141, the first break 141 is located at the center in the extending direction of the extension segment 164, which is beneficial to making the light output of the light-emitting units 120 near the first break 141 more uniform and stable.
[0063] Exemplarily, on the extension segment 164 provided with the first break 141, the dimension range of the first break 141 in the extending direction of the extension segment 164 is 3μm - 5μm. This can avoid the dimension of the first break 141 in the extending direction of the extension segment 164 being too small, which is beneficial to reducing the manufacturing difficulty of the first break 141. Additionally, it can also avoid the dimension of the first break 141 in the extending direction of the extension segment 164 being too large, which is beneficial to improving touch accuracy. For example, the dimension of the first break 141 in the extending direction of the extension segment 164 can be 3μm, 3.5μm, 4μm, 5μm or any number between 3μm - 5μm.
[0064] Exemplarily, on the extension segment 164 provided with the second break 142, the second break 142 is located at the center in the extending direction of the extension segment 164, which is beneficial to making the light output of the light-emitting units 120 near the second break 142 more uniform and stable.
[0065] Exemplarily, on the extension segment 164 provided with the second break 142, the dimension range of the second break 142 in the extending direction of the extension segment 164 is 3μm - 5μm. This can avoid the dimension of the second break 142 in the extending direction of the extension segment 164 being too small, which is beneficial to reducing the manufacturing difficulty of the second break 142. Additionally, it can also avoid the dimension of the second break 142 in the extending direction of the extension segment 164 being too large, which is beneficial to improving touch accuracy. For example, the dimension of the second break 142 in the extending direction of the extension segment 164 can be 3μm, 3.5μm, 4μm, 5μm or any number between 3μm - 5μm.
[0066] Exemplarily, refer to Figure 5, the second sub-touch trace 162 includes a seventh extension segment 1647. The seventh extension segment 1647 is disposed on a side of the second sub-touch trace 162 facing the corresponding first sub-touch trace 161. The third break 143 is disposed on the seventh extension segment 1647, and the third break 143 is located at the center of the extension direction of the seventh extension segment 1647, which is beneficial to making the light emission of the light-emitting unit 120 near the third break 143 more uniform and stable.
[0067] Exemplarily, the dimension range of the third break 143 along the extension direction of the seventh extension segment 1647 is 3μm - 5μm. This can avoid the dimension of the third break 143 along the extension direction of the seventh extension segment 1647 being too small, which is beneficial to reducing the manufacturing difficulty of the third break 143. Additionally, it can also avoid the dimension of the third break 143 along the extension direction of the seventh extension segment 1647 being too large, which is beneficial to improving touch accuracy. For example, the dimension of the third break 143 along the extension direction of the seventh extension segment 1647 can be 3μm, 3.5μm, 4μm, 5μm or any number between 3μm - 5μm.
[0068] Exemplarily, referring to Figure 5 , the third sub-touch trace 163 includes an eighth extension segment 1648. The eighth extension segment 1648 is disposed on a side of the third sub-touch trace 163 facing the corresponding first sub-touch trace 161. The fourth break 144 is disposed on the eighth extension segment 1648, and the fourth break 144 is located at the center of the extension direction of the eighth extension segment 1648, which is beneficial to making the light emission of the light-emitting unit 120 near the fourth break 144 more uniform and stable.
[0069] Exemplarily, the dimension range of the fourth break 144 along the extension direction of the eighth extension segment 1648 is 3μm - 5μm. This can avoid the dimension of the fourth break 144 along the extension direction of the eighth extension segment 1648 being too small, which is beneficial to reducing the manufacturing difficulty of the fourth break 144. Additionally, it can also avoid the dimension of the fourth break 144 along the extension direction of the eighth extension segment 1648 being too large, which is beneficial to improving touch accuracy. For example, the dimension of the fourth break 144 along the extension direction of the eighth extension segment 1648 can be 3μm, 3.5μm, 4μm, 5μm or any number between 3μm - 5μm.
[0070] Exemplarily, the fifth break 145 is disposed at the center of the extension direction of the fifth extension segment 1645, which is beneficial to making the light emission of the light-emitting unit 120 near the fifth break 145 more uniform and stable.
[0071] Exemplarily, the size of the fifth break 145 in the extending direction of the fifth extension section 1645 ranges from 3 μm to 5 μm, which can prevent the size of the fifth break 145 in the extending direction of the fifth extension section 1645 from being too small, facilitating the reduction of the manufacturing difficulty of the fifth break 145. Additionally, it can also prevent the size of the fifth break 145 in the extending direction of the fifth extension section 1645 from being too large, which is beneficial to improving touch accuracy. For example, the size of the fifth break 145 in the extending direction of the fifth extension section 1645 can be 3 μm, 3.5 μm, 4 μm, 5 μm, or any value between 3 μm and 5 μm.

[0074] In some embodiments, referring to Figure 8 , a packaging layer 150 can be provided between the light-emitting unit 120 and the touch trace 160. The packaging layer 150 can prevent water, oxygen, etc. from invading the light-emitting unit 120, thereby forming a packaging protection for the light-emitting unit 120.
[0075] In some embodiments, the display panel 100 may further include auxiliary touch traces. The touch trace 160 can be located on the side of the auxiliary touch trace away from the substrate 110, or the touch trace 160 can be located on the side of the auxiliary touch trace facing the substrate 110.

Each second touch electrode may include a plurality of second touch electrode blocks arranged along the second direction Y, and the second touch electrode blocks may be a grid structure formed by the intersecting touch traces 160. Since the touch electrode blocks (the first touch electrode blocks and the second touch electrode blocks) are in a grid structure, the touch electrode blocks in the grid structure can be located in the non-opening area of the display panel 100 so that the grid structure does not block the light-emitting units in the opening area, and the influence of the touch trace 160 on the light output of the light-emitting units can be reduced.
[0079] Exemplarily, a plurality of touch electrode blocks of one of the first touch electrode and the second touch electrode may be connected by the touch trace 160 to form an uninterrupted structure. A plurality of touch electrode blocks of the other of the first touch electrode and the second touch electrode are disconnected and can be connected by a bridge formed by an auxiliary touch trace. The bridge may be located at the crossing position of the first touch electrode and the second touch electrode to avoid short circuit at the crossing position of the first touch electrode and the second touch electrode.

[0081] Exemplarily, the material of at least one of the auxiliary touch trace and the touch trace 160 may include metals such as titanium, silver, copper, aluminum, molybdenum, or alloys, or conductive oxides (such as Indium Tin Oxide (ITO for short), Indium Zinc Oxide (IZO for short), Zinc Oxide (ZnO), Aluminum Zinc Oxid (AZO for short)), Gallium Zinc Oxide, Tantalum Titanium Oxide, Tin Oxide, Cadmium Oxide, Indium Oxide), or any one or more of them.
