[0002] With the rapid development of display technologies, touch display products have been widely used in various industries. In some touch display products, there is coupling between the touch unit and the scanning line, which will cause display differences, resulting in the appearance of slit phenomena in the display product and affecting the display effect of the display product.

[0003] Therefore, how to improve the above technical problems has become one of the technical problems to be solved urgently at the present stage. Summary of the Invention

[0013] The technical solutions provided by the embodiments of the present disclosure have the following advantages compared with the prior art:

[0014] The present disclosure provides a display panel and a display device. The display device includes a display panel, the display panel includes a plurality of pixels arranged in an array, a plurality of touch units, a first touch trace, and a first scan line. The first touch trace extends in a first direction, and the first touch trace is electrically connected to the touch units; the first scan line extends in a second direction and is located between adjacent pixel rows along the first direction. The touch unit includes a plurality of first electrodes, and the display panel further includes a connection portion for electrically connecting the first electrodes. The connection portion includes a first connection portion for electrically connecting the first electrodes adjacent along the second direction. The present disclosure sets at least a part of the orthographic projection of the first connection portion on the display panel not to overlap with the orthographic projection of the first scan line on the display panel. In this way, the overlap between the first connection portion and the first scan line is reduced, thereby reducing the coupling capacitance between the first connection portion and the first scan line, which is beneficial to reducing the influence of the coupling capacitance on the potential of the touch unit.

At the same time, for two adjacent touch units along the first direction, the coupling capacitance corresponding to at least one row of pixels in one touch unit close to the other touch unit is reduced, reducing the influence on the display effect, improving the display difference of the display panel, and being beneficial to improving the slit phenomenon caused by the coupling capacitance, thereby being beneficial to improving the display effect of the display panel.

[0028] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0029] In the following description, many specific details are set forth to facilitate a thorough understanding of the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0030] The inventors found in their research that in some display panels, there is coupling between the touch control unit and the scanning line, which will cause display differences, resulting in a seam phenomenon in the display product and affecting the display effect of the display product. Specifically, Figure 1 The figure shows a timing diagram of a scanning signal in the prior art, Figure 2 The figure shows a schematic diagram of a touch control unit and a scanning line in the prior art. Please refer to Figure 1 and Figure 2, one touch unit 20' corresponds to multiple rows of pixels, and the pixels emit light through the scanning signal provided by the scanning line 40'. The touch unit 20' overlaps with the scanning line 40', and there is a coupling capacitor, which affects the potential of the touch unit 20'. Usually, the touch unit 20' is reused as a common electrode. There is a voltage difference between the pixel electrode and the common electrode of the display panel. The formed electric field deflects the liquid crystal, thereby causing the pixel to emit light. However, due to the existence of the coupling capacitor, the potential of the common electrode is affected, thereby affecting the display effect. Please refer to Figure 1 In the timing sequence shown, there are rising and falling edges between the scanning signals corresponding to different pixel rows. For the entire touch control unit 20', the coupling of the rising and falling edges corresponding to the pixels in the middle row in the same touch control unit 20' can be offset. In this way, the display of the middle row in the same touch control unit 20' is the same or the difference is small. Figure 2 In the viewing angle shown, the coupling corresponding to at least one row of pixels located above and at least one row of pixels located below in the touch unit 20' cannot be offset. At the rising and falling edges of the scan signal, the coupling capacitance between the scan line and the touch unit is different from that of the middle row, resulting in the potential of the common electrode being affected by the coupling capacitance, which in turn causes the voltage difference between the pixel electrode and the common electrode to be affected. The liquid crystal deflection angle is different from that of the middle row of pixels, resulting in display differences. Between the touch units 20' (common electrodes) adjacent along the first direction, the voltage difference between the corresponding pixel electrodes and the common electrode of the last at least one row of pixels in the upper touch unit 20' and the first few rows of pixels in the lower touch unit is greatly different due to the difference in coupling capacitance, resulting in the appearance of horizontal stripes or white lines between the touch units 20' (common electrodes) adjacent along the first direction, also known as the "slit" phenomenon, which affects the display effect of the display panel.

[0031] Therefore, how to improve the above technical problems has become one of the technical problems that need to be solved urgently at this stage.

[0032] In view of this, the present disclosure provides a display panel and a display device to improve the display effect of the display panel.

[0033] Figure 3 FIG. 1 is a schematic diagram of a display panel provided by an embodiment of the present disclosure, please refer to FIG. Figure 3, the present disclosure provides a display panel 100, including: a plurality of pixels 10 arranged in an array; a plurality of touch units 20, the touch unit 20 including a plurality of electrically connected first electrodes 21; a first touch trace 30 extending along a first direction F1 and located between adjacent pixel columns along a second direction F2, the first direction F1 and the second direction F2 both being parallel to the display panel 100, the first direction F1 and the second direction F2 intersecting, the first touch trace 30 being electrically connected to the touch unit 20; a first scan line 40 extending along the second direction F2 and located between adjacent pixel rows along the first direction F1; a connection portion 50 for electrically connecting the first electrodes 21, the connection portion 50 including a first connection portion 51 for electrically connecting the first electrodes 21 adjacent along the second direction F2; at least a part of the orthographic projection of the first connection portion 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100.

[0034] It should be noted that the drawings of the present disclosure are only schematic and do not represent the actual structure and dimensions of the display panel 100. For example, Figure 3 the connection portion 50 is shown as a rectangle in, but the present disclosure is not limited thereto and may also be any other possible shape. It should also be noted that the "pixel 10" mentioned in the present disclosure may be a sub-pixel or a pixel unit including a plurality of sub-pixels.

[0035] Specifically, the present disclosure provides a display panel 100, the display panel 100 including a plurality of pixels 10 arranged in an array and a plurality of touch units 20, the touch unit 20 including a plurality of first electrodes 21 corresponding to the pixels 10, and the first electrodes 21 in the same touch unit 20 being electrically connected. The display panel 100 further includes a plurality of first touch traces 30 extending along the first direction F1 and disposed between adjacent pixel columns, the first touch traces 30 being electrically connected to the touch unit 20 and used for transmitting touch signals. The display panel 100 further includes a plurality of first scan lines 40 extending along the second direction F2 and disposed between adjacent pixel rows, the first scan lines 40 being used for transmitting scan signals to the pixels 10. It should be noted that the pixel 10 includes a driving transistor (not shown in the figure), the control end of the driving transistor is connected to the first scan line, the scan signal is a signal for controlling the driving transistor to conduct or cut off, and when the scan signal controls the driving transistor to conduct, the data signal is transmitted to the corresponding pixel 10 to realize the scanning of the pixel 10 and the light emission of the pixel.

[0036] It should also be noted that the first electrodes 21 in the same touch unit 20 are electrically connected, and the display panel 100 is provided with a connection portion 50 for electrically connecting the first electrodes 21. The display panel 100 includes a plurality of connection portions 50, where the connection portion 50 includes a first connection portion 51 for electrically connecting the first electrodes 21 adjacent in the second direction F2. In other words, the first connection portion 51 is used to electrically connect the adjacent first electrodes 21 in the same pixel row. The present disclosure is configured such that the orthographic projection of at least a part of the first connection portion 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100. In this way, the overlap between the first connection portion 51 and the first scan line 40 is reduced, thereby reducing the coupling capacitance between the first connection portion 51 and the first scan line 40, which is beneficial to reducing the influence of the coupling capacitance on the potential of the touch unit 20. When the touch unit 20 is multiplexed to drive the liquid crystal to deflect the pixels to emit light as a common electrode, the influence of the coupling capacitance on the potential of the common electrode is reduced, thereby reducing the influence on the voltage difference between the common electrode and the pixel electrode, which is beneficial to improving the display difference. At the same time, for two adjacent touch units 20 in the first direction F1, the coupling capacitance corresponding to at least one row of pixels in one touch unit 20 close to the other touch unit 20 is reduced, reducing the influence on the display effect, improving the display difference of the display panel 100, which is beneficial to improving the slit phenomenon caused by the coupling capacitance, and thus beneficial to improving the display effect of the display panel 100.

[0037] For the orthographic projection of at least a part of the first connection portion 51 on the display panel 100 not overlapping with the orthographic projection of the first scan line 40 on the display panel 100, an optional implementation manner provided by the present disclosure is that the connection portion 50 includes a plurality of first connection portions 51, and the orthographic projection of at least one first connection portion 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100. It should be noted that the present disclosure Figure 3 is only illustrated by taking the touch unit 20 including 20 first electrodes 21 and 16 first connection portions 51 as an example, and is not limited thereto. Among the 16 first connection portions 51, the orthographic projection of at least a part of the first connection portions 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100. Exemplarily, the orthographic projection of 2 first connection portions 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100 at all; for another example, the orthographic projection of 10 first connection portions 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100 at all; for yet another example, the orthographic projection of at least 6 first connection portions 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100 at all. In this embodiment, there is at least one first connection portion 51 that does not overlap with the first scan line 40 at all. For example, Figure 3The first connection part 51-a in [reference] does not overlap with the first scan line 40. Thus, at least one first connection part 51 does not overlap with the first scan line 40, reducing the coupling capacitance between the first connection part 51 and the first scan line 40.

[0038] Another alternative embodiment provided by the present disclosure is that the connection part 50 includes a plurality of first connection parts 51. The orthographic projection of a partial area of at least one first connection part 51 on the display panel 100 does not overlap with the orthographic projection of the first scan line 40 on the display panel 100. Please refer to Figure 3 the first connection part 51-b in [reference]. The first connection part 51-b overlaps with the first scan line 40. However, along the first direction F1, the first connection part 51-b does not completely cover the first scan line 40. Thus, the overlapping area between the first connection part 51 and the first scan line 40 is reduced, thereby reducing the coupling capacitance between the first connection part 51 and the first scan line 40. Figure 4 The following figure shows an overlapping schematic diagram of a first connection part and a first scan line provided by an embodiment of the present disclosure. Please refer to Figure 3 and Figure 4 , exemplarily, the orthographic projection of a partial area of the first connection part 51 on the display panel 100 overlaps with the orthographic projection of the first scan line 40 on the display panel 100. Along the first direction F1, the overlapping length of the orthographic projection of the first connection part 51 on the display panel 100 and the orthographic projection of the first scan line 40 on the display panel 100 is W1, and the length of the first scan line 40 is W2, where W1 < W2.

[0039] It should be noted that the present disclosure does not specifically limit the shape of the display panel 100. The shape of the display panel 100 can be a regular rectangle, or an irregular water-drop screen, notch screen, rounded-corner screen, or other special-shaped screens, etc.

[0040] Figure 5 The following figure shows another schematic diagram of a display panel provided by an embodiment of the present disclosure. Please refer to Figure 5 , in an alternative embodiment of the present disclosure, the first electrode 21 includes a first A electrode 211 and a first B electrode 212 adjacent to each other along the second direction F2. The first connection part 51 is located between the first A electrode 211 and the first B electrode 212 and is electrically connected to the first A electrode 211 and the first B electrode 212.

[0041] Specifically, the connecting portion 50 includes a first connecting portion 51. The first connecting portion 51 is used to connect two first electrodes 21 arranged along the second direction F2. The first electrodes 21 include a first A electrode 211 and a first B electrode 212. The first A electrode 211 and the first B electrode 212 are arranged along the second direction F2, and the first A electrode 211 and the first B electrode 212 are located in the same pixel row. The first connecting portion 51 is electrically connected to the first A electrode 211 and the first B electrode 212 respectively. In this embodiment, the first connecting portion 51 connects the adjacent first A electrode 211 and first B electrode 212 along the second direction F2. The orthographic projection of the first A electrode 211 on the display panel 100 does not overlap with the orthographic projection of the first scanning line 40 on the display panel 100, and the orthographic projection of the first B electrode 212 on the display panel 100 does not overlap with the orthographic projection of the first scanning line 40 on the display panel 100. The first A electrode 211 and the first B electrode 212 are located on the same side of the first scanning line 40. With such an arrangement, it is beneficial for the first connecting portion 51 to avoid the first scanning line 40 as much as possible, thereby reducing the coupling capacitance between the first connecting portion 51 and the first scanning line 40, which is beneficial to improving the slit phenomenon caused by the coupling capacitance, and thus beneficial to improving the display effect of the display panel 100.

[0042] Please continue to refer to Figure 5 , further, an optional embodiment provided by the present disclosure is that along the first direction F1, the first connecting portion 51 includes a first symmetry axis 61 extending along the second direction F2, and the first electrode 21 connected by the first connecting portion 51 includes a second symmetry axis 62, and the first symmetry axis 61 and the second symmetry axis 62 coincide.

[0043] Specifically, the present disclosure provides an embodiment of the relative position between the first connecting portion 51 and the first electrode 21. In this embodiment, the first symmetry axis 61 of the first connecting portion 51 extending along the second direction F2 coincides with the second symmetry axis 62 of the first electrode 21, that is, along the first direction F1, the first connecting portion 51 is located at the center line of the first electrode 21 it connects and extending along the second direction F2. Thus, along the first direction F1, the first connecting portion 51 is at a relatively far distance from the first scanning lines 40 on both sides of it, which is more beneficial to reducing the coupling capacitance between the first connecting portion 51 and the first scanning lines 40, beneficial to improving the slit phenomenon caused by the coupling capacitance, and thus beneficial to improving the display effect of the display panel 100.

[0044] Figure 6 The figure shows a schematic diagram of yet another display panel provided by an embodiment of the present disclosure. Figure 7 The figure shows the present disclosure Figure 6 The enlarged schematic diagram of the area Q1 in, please refer to Figure 6 and Figure 7, in an alternative embodiment of the present disclosure, the first connection portion 51 includes a first connection part A 511, a first connection part B 512, and a connection bridge 513; the orthographic projection of the connection bridge 513 on the display panel 100 overlaps with the orthographic projection of the first touch trace 30 on the display panel 100; the first end of the connection bridge 513 is connected to the first connection part A 511, and the second end is connected to the first connection part B 512. The first connection part A 511 and the first connection part B 512 are respectively connected to different first electrodes 21.

[0045] Specifically, along the second direction F2, the first connection portion 51 includes the first connection part A 511, the connection bridge 513, and the first connection part B 512 that are connected in sequence. The first connection portion 51 connects two different first electrodes 21. Among them, the first connection part A 511 connects one of the first electrodes 21 and the connection bridge 513, and the first connection part B 512 connects the other first electrode 21 and the connection bridge 513, so as to electrically connect the two first electrodes 21 through the first connection portion 51. There is a first touch trace 30 between the two first electrodes 21. In the first connection portion 51, the orthographic projection of the connection bridge 513 on the display panel 100 overlaps with the orthographic projection of the first touch trace 30. Optionally, both the connection bridge 513 and the first touch trace 30 are metal structures. When the connection bridge 513 and the first touch trace 30 overlap, a coupling capacitance will be generated, which will affect the display effect of the display panel 100. In order to reduce the coupling capacitance between the first connection portion 51 and the first touch trace 30, an alternative embodiment provided by the present disclosure is that along the first direction F1, the length d1 of the connection bridge 513 is less than the length d2 of the first connection part A 511, and the length d1 of the connection bridge 513 is less than the length d3 of the first connection part B 512.

[0046] Specifically, in the first connection portion 51 of this embodiment, the length d1 of the connection bridge 513 along the first direction F1 is less than the length of the first connection part A 511 along the first direction F1, and the length d1 of the connection bridge 513 along the first direction F1 is also less than the length of the first connection part B 512 along the first direction F1. In this way, the first connection portion 51 with a "work" - shaped structure is formed. By reducing the length of the connection bridge 513 along the first direction F1 that overlaps with the first touch trace 30, the present disclosure reduces the overlap between the first connection portion 51 and the first touch trace 30, which is beneficial to reducing the coupling capacitance between the first connection portion 51 and the first touch trace 30, and further beneficial to improving the display effect of the display panel 100.

[0047] Optionally, along the first direction F1, the length of the connection bridge 513 is d1, and d1 ≥ 4 μm.

[0048] Specifically, the connection bridge 513 is used to electrically connect the first connection part A 511 and the first connection part B 512, so as to electrically connect the first electrode 21. When the length d1 of the connection bridge 513 along the first direction F1 < 4 μm, the length of the connection bridge 513 is too small, and the risk of disconnection between the first connection part A 511 and the first connection part B 512 is relatively high, which is not conducive to the electrical connection of the first electrode 21 and affects the transmission of touch signals. Therefore, in the present disclosure, the length d1 of the connection bridge 513 along the first direction F1 ≥ 4 μm. At the same time, the length d1 of the connection bridge 513 along the first direction F1 is less than the length d2 of the first connection part A 511 and the length d3 of the first connection part B 512. In this way, it is both beneficial to reduce the risk of disconnection between the first connection part A 511 and the first connection part B 512, and to ensure the normal internal connection of the first connection part 51 as much as possible, which is conducive to ensuring the transmission of touch signals. It is also beneficial to reduce the overlapping area between the first connection part 51 and the first touch trace 30, thereby reducing the coupling capacitance between the first connection part 51 and the first touch trace 30, which is beneficial to improving the slit phenomenon caused by the coupling capacitance, and further beneficial to improving the display effect of the display panel 100. An optional implementation provided by the present disclosure is that the length d1 of the connection bridge 513 along the first direction F1 = 5 μm; another optional implementation provided by the present disclosure is that the length d1 of the connection bridge 513 along the first direction F1 = 10 μm; still another optional implementation provided by the present disclosure is that the length d1 of the connection bridge 513 along the first direction F1 ≥ 8 μm.

[0049] Please refer to Figure 3 , in an optional implementation manner of the present disclosure, at least part of the first connection part 51 is electrically connected to the first touch trace 30 through a via 500.

[0050] Specifically, the first touch trace 30 is used to transmit touch signals to the touch unit 20, and the first touch trace 30 needs to be electrically connected to the touch unit 20. In order to reduce the coupling capacitance between the first touch trace 30 and the first electrode 21, the first touch trace 30 is usually arranged between adjacent first electrodes 21, that is, the orthographic projection of the first touch trace 30 on the display panel 100 does not overlap with the orthographic projection of the first electrode 21 on the display panel 100. Therefore, at least part of the first connection part 51 (such as Figure 3 the first connection part 51-h in) is electrically connected to the first touch trace 30 through a via 500, so as to realize the electrical connection between the first touch trace 30 and the touch unit 20. It should be noted that the position, size, shape, etc. of the via 500 in the drawings are only for illustration and do not represent its actual structure.

[0051] Further, for the first connection portion 51 electrically connected to the first touch trace 30 through the via 500, the embodiments of the present disclosure define the size of the first connection portion 51. Optionally, the length of the first connection portion 51 along the first direction F1 that is electrically connected to the first touch trace 30 through the via 500 is h1, and 12 μm ≤ h1 ≤ 20 μm.

[0052] Specifically, since electrical connection between the first connection portion 51 and the first touch trace 30 needs to be achieved through the via 500, therefore, the first connection portion 51 connected to the first touch trace 30 through the via 500 needs to appropriately increase its size compared to a conventional first connection portion 51. However, when the size of the first connection portion 51 is too large, it will affect the aperture ratio of the display panel 100, and further affect the display effect of the display panel 100. Therefore, the present disclosure sets that the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 is 12 μm ≤ h1 ≤ 20 μm. When h1 < 12 μm, the length of the first connection portion 51 along the first direction F1 is too small, which is not conducive to drilling and connecting with the first touch trace 30; when h1 > 20 μm, the length of the first connection portion 51 along the first direction F1 is too large, which will affect the aperture ratio of the display panel 100, and further affect the display effect of the display panel 100. Therefore, the present disclosure sets the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 to be 12 μm ≤ h1 ≤ 20 μm. In this way, it is both conducive to ensuring the connection between the first connection portion 51 and the first touch trace 30 through the via 500, and conducive to reducing the impact on the aperture ratio of the display panel 100, thereby being conducive to improving the display effect of the display panel 100. An optional implementation provided by the present disclosure is that the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 is h1 = 13 μm; another optional implementation provided by the present disclosure is that the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 is h1 = 15 μm; still another optional implementation provided by the present disclosure is that the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 is h1 = 18 μm; yet another optional implementation provided by the present disclosure is that the length h1 of the first connection portion 51 connected to the first touch trace 30 through the via 500 along the first direction F1 is 14 μm ≤ h1 ≤ 17 μm.

[0053] It should be noted that only the range of the length h1 of the first connection part 51 in the first direction F1 is set in this disclosure. The orthographic projection of the first connection part 51 on the display panel 100 is usually a square, that is, the length of the first connection part 51 in the second direction F2 is equal to the length of the first connection part 51 in the first direction F1. Therefore, the length range of the first connection part 51 in the second direction F2 can also adopt the value range of h1, that is, it takes values between 12 μm and 20 μm (including the endpoints). This disclosure is only illustrated by this example and is not limited thereto.

[0054] Figure 8 The following shows a schematic diagram of another display panel provided by an embodiment of this disclosure. Please refer to Figure 8 Optionally, the display panel 100 further includes auxiliary traces 31. The auxiliary traces 31 extend in the first direction F1 and are arranged in the second direction F2. The auxiliary traces 31 are provided on the same layer as the first touch traces 30 and are not connected to the touch unit 20. The auxiliary traces 31 and the first touch traces 30 are both the first metal traces 300, and the distance between adjacent first metal traces 300 is equal.

[0055] Specifically, the display panel 100 further includes auxiliary traces 31. The auxiliary traces 31 and the first touch traces 30 both extend in the first direction F1 and are arranged in the second direction F2. The first touch traces 30 are electrically connected to the touch unit 20, the auxiliary traces 31 are not connected to the touch unit 20, the auxiliary traces 31 and the first touch traces 30 are provided on the same layer, the auxiliary traces 31 and the first touch traces 30 are both the first metal traces 300, and the distance between adjacent first metal traces 300 is equal. In other words, an auxiliary trace 31 may be adjacent to an auxiliary trace 31 or may be adjacent to a first touch trace 30. Similarly, a first touch trace 30 may be adjacent to an auxiliary trace 31 or may be adjacent to a first touch trace 30. How the first touch traces 30 and the auxiliary traces 31 are specifically arranged can be designed according to actual needs. Along the second direction F2, the distance between adjacent first metal traces 300 is equal. In this way, it is beneficial to improve the uniformity of the arrangement of the first metal traces 300 in the display panel 100.

[0056] Please continue to refer to Figure 8 In an optional implementation manner of this disclosure, one touch unit 20 is electrically connected to multiple first touch traces 30. Exemplarily, one touch unit 20 corresponds to 40 first metal traces 300, including 32 first touch traces 30 and 8 auxiliary traces 31. The 40 first metal traces 300 can be arranged according to actual needs, and the distance between the first metal traces 300 is equal. Optionally, the auxiliary traces 31 are arranged on both sides of the first touch traces 30, that is, multiple first touch traces 30 are concentrated in the middle, and the auxiliary traces 31 are arranged on both sides.

[0057] It should be noted that, in some embodiments, one touch control unit 20 of the display panel 100 corresponds to one first touch trace 30; in other embodiments, one touch control unit 20 of the display panel 100 corresponds to multiple first touch traces 30; it can be set according to actual situations, and the present disclosure does not make specific limitations. It should also be noted that the number of first touch traces 30 in the display panel 100 can be set according to actual situations, and the present disclosure does not make specific limitations. At the same time, the present disclosure does not make specific limitations on whether a first touch trace 30 must be provided between any two columns of pixels. In other words, between any two columns of pixels in the display panel 100, it may or may not include a first touch trace 30.

[0058] Please continue to refer to Figure 8 , in an alternative embodiment of the present disclosure, the connection portion 50 further includes a second connection portion 52, and the second connection portion 52 is used for electrically connecting multiple first electrodes 21; the orthographic projection of the second connection portion 52 on the display panel 100 overlaps with the orthographic projection of the auxiliary trace 31 on the display panel 100.

[0059] Specifically, the touch control unit 20 includes multiple first electrodes 21, and the first electrodes 21 are electrically connected to each other. The first electrodes 21 arranged along the second direction F2 are electrically connected through the first connection portion 51, that is, the first electrodes 21 in the same row are electrically connected through the first connection portion 51, and the first electrodes 21 in different rows also need to be electrically connected. Therefore, the present disclosure provides the second connection portion 52, and the second connection portion 52 electrically connects multiple first electrodes 21, which can not only electrically connect the first electrodes 21 arranged along the second direction F2, but also electrically connect the first electrodes 21 arranged along the first direction F1. With this setting, it is beneficial to reduce the number of connection portions 50 in the display panel 100, improve the aperture ratio of the display panel 100, and thus improve the display effect of the display panel 100. It should be noted that, for the purpose of clearly showing the first connection portion 51 and the second connection portion 52 in the drawings of the present disclosure, different fillings are used for the first connection portion 51 and the second connection portion 52, and the first connection portion 51 and the second connection portion 52 may have the same or different structural materials in essence.

[0060] The orthographic projection of the second connection portion 52 on the display panel 100 overlaps with the orthographic projection of the auxiliary trace 31 on the display panel 100, and the orthographic projection of the second connection portion 52 on the display panel 100 does not overlap with the orthographic projection of the first touch trace 30 on the display panel 100. The first touch trace 30 is electrically connected to the touch unit 20 and is used to transmit touch signals. The second connection portion 52 provided in the embodiment of the present disclosure does not overlap with the first touch trace 30, which is beneficial to reducing the coupling capacitance between the connection portion 50 and the first touch trace 30, thereby reducing the influence on the transmission of touch signals and the display effect, and further being beneficial to improving the touch performance and display effect of the display panel 100.

[0061] Figure 9 The following is a schematic diagram of another display panel provided by the embodiment of the present disclosure. Please refer to Figure 9 In an alternative embodiment of the present disclosure, the connection portion 50 further includes a third connection portion 53. The third connection portion 53 is used to connect the first electrodes 21 arranged along the first direction F1, and the orthographic projection of the third connection portion 53 on the display panel 100 does not overlap with the orthographic projection of the first touch trace 30 on the display panel 100.

[0062] It should be noted that, in order to clearly show the first connection portion 51 and the third connection portion 53 in the drawings of the present disclosure, different fillings are used for the first connection portion 51 and the third connection portion 53. Substantially, the first connection portion 51 and the third connection portion 53 can be made of the same material and process, or can be made of different materials and processes.

[0063] Specifically, the third connection portion 53 provided in this embodiment can achieve the electrical connection between the first electrodes 21 arranged along the first direction F1. The third connection portion 53 does not overlap with the first touch trace 30. On the one hand, it is beneficial to reduce the coupling capacitance between the connection portion 50 and the first touch trace 30, thereby reducing the influence on the transmission of touch signals, and further being beneficial to improving the touch performance of the display panel 100. On the other hand, please refer to Figure 8 and Figure 9 Figure 9 In Figure 8 the embodiment shown, the setting of the auxiliary trace 31 is beneficial to improving the layout uniformity of the first metal trace 300. Figure 9 In

[0064] It should also be noted that Figure 9 In the illustrated embodiment, the connecting portion 50 includes a first connecting portion 51 and a third connecting portion 53. The first connecting portion 51 is used for electrically connecting two first electrodes 21 arranged along the second direction, and at least a part of the positive projection of the first electrodes 21 on the display panel 100 does not overlap with the positive projection of the first scanning line 40 on the display panel 100. With such a setting, it is beneficial to reduce the overlap between the connecting portion 50 and the first scanning line 40, thereby reducing the coupling capacitance between the connecting portion 50 and the first scanning line 40, which is beneficial to improving the slit phenomenon caused by the coupling capacitance, and thus beneficial to improving the display effect of the display panel 100. The third connecting portion 53 does not overlap with the first touch trace 30. Compared with Figure 8 the illustrated embodiment, it is equivalent to canceling the setting of the auxiliary trace 31, reducing the coupling capacitance between the connecting portion 50 and other metal film layers, and also beneficial to improving the display effect of the display panel 100. Whether it is the design of the first connecting portion 51 to reduce the overlap between the connecting portion 50 and the first scanning line 40, or the design of canceling the auxiliary trace 31 and setting the third connecting portion 53, both are beneficial to improving the display effect of the display panel 100. In actual production, the two design methods can appear alone or in combination, and the present disclosure does not make specific limitations.

[0065] Please continue to refer to Figure 9 , in an alternative embodiment of the present disclosure, the third connecting portion 53 extends along the first direction F1 and is electrically connected to the first electrode row 210 within the same touch unit 20; the first electrode row 210 includes a plurality of first electrodes 21 arranged along the second direction F2.

[0066] Specifically, the third connecting portion 53 in this embodiment is used for electrically connecting the first electrode row 210 within the same touch unit 20. The third connecting portion 53 extends along the first direction F1. While realizing the electrical connection of the first electrodes 21, it increases the connection area between the first electrodes 21, which is beneficial to reducing the resistance of the touch signal transmission within the touch unit, beneficial to the transmission of the touch signal, and thus beneficial to improving the touch performance of the display panel 100. At the same time, the third connecting portion 53 does not overlap with the first touch trace 30, which is beneficial to reducing the coupling capacitance between the connecting portion 50 and the first touch trace 30, and thus beneficial to improving the display effect of the display panel 100.

[0067] Figure 10 The figure shows a schematic diagram of another display panel provided by an embodiment of the present disclosure. Please refer to Figure 10 , in an alternative embodiment of the present disclosure, the third connecting portion 53 is located at the edge of the touch unit 20.

[0068] Specifically, in this embodiment, the third connecting portion 53 is disposed at the edge of the touch control unit 20. In this way, it is further beneficial to reduce the overlap between the third connecting portion 53 and the first scanning line 40, thereby reducing the coupling capacitance between the connecting portion 50 and the first scanning line 40, and further improving the display effect of the display panel 100.

[0069] It should be noted that, please refer to Figures 8 - 10 , from the perspective shown in the figure, the first touch trace 30 can extend from bottom to top with the same or substantially the same length. As Figure 8 shown, the lengths of the first touch traces 30 in the display panel 100 are the same or substantially the same. The orthographic projection of the touch control unit 30 on the display panel 100 overlaps with the orthographic projections of the plurality of first touch traces 30 on the display panel 100, and the touch control unit 20 is electrically connected to the corresponding first touch trace 30 by punching holes. It can also be as Figure 9 and Figure 10 shown, the lengths of the first touch traces 30 are different. Each first touch trace 30 extends from bottom to top. After being connected to the corresponding touch control unit 20, it does not extend upward. Therefore, the orthographic projection of the uppermost row of touch control units 20 in the display panel 100 on the display panel 100 only overlaps with the orthographic projection of the first touch trace 30 connected to itself on the display panel 100. As described above, the setting manner of the first touch trace 30 can be flexibly set according to actual situations, and the present disclosure does not make specific limitations.

[0070] Please refer to Figure 3 , in an alternative embodiment of the present disclosure, the connecting portion 50 and the first electrode 21 are disposed on the same layer.

[0071] It should be noted that the connecting portion 50 is used to realize the electrical connection of the first electrodes 21 within the same touch control unit 20. In the embodiments of the present disclosure, the connecting portion 50 and the first electrode 21 are disposed on the same layer. During manufacturing, the connecting portion 50 and the first electrode 21 can be formed in the same manufacturing process, which is beneficial to simplifying the manufacturing process and reducing the manufacturing cost of the display panel 100.

[0072] Please continue to refer to Figure 3 , optionally, the length of the connecting portion 50 along the first direction F1 is h2, and h2≥10μm.

[0073] It should be noted that in the embodiments of the present disclosure, the connecting portion 50 includes a first connecting portion 51, a second connecting portion 52, and a third connecting portion 53. The purpose of providing the connecting portion 50 is to electrically connect multiple first electrodes 21 in the same touch unit 20. Specifically, how to arrange the first connecting portion 51, the second connecting portion 52, and the third connecting portion 53 can be designed according to actual requirements. In the length h2 of the connecting portion 50 along the first direction F1 mentioned in this embodiment, the connecting portion 50 includes the first connecting portion 51, the second connecting portion 52, and the third connecting portion 53. That is, the first connecting portion 51 needs to meet the limitation of h2, the second connecting portion 52 needs to meet the limitation of h2, and the third connecting portion 53 also needs to meet the limitation of h2. In the embodiments of the present disclosure, the length h1 of the first connecting portion 51 along the first direction F1 is also mentioned. h1 refers to the length of the first connecting portion 51 that is electrically connected to the first touch trace 30 through the via 500. Since the via 500 needs to be provided, compared with the length h2 of a general first connecting portion 51 along the first direction F1, the length h1 of the first connecting portion 51 that is electrically connected to the first touch trace 30 through the via 500 needs to be appropriately increased. Therefore, h1 needs to meet h1≥12μm, and h2 needs to meet h2≥10μm.

[0074] Specifically, the connecting portion 50 is used to connect the first electrodes 21. The length of the connecting portion 50 along the first direction F1 is h2. When the length h2 of the connecting portion 50 along the first direction F1 is less than 10μm, the length of the connecting portion 50 along the first direction F1 is relatively short, and the connection effect between the connecting portion 50 and the first electrodes 21 is poor, affecting the transmission of touch signals. Therefore, it is set that the length h2 of the connecting portion 50 along the first direction F1≥10μm. In this way, it is beneficial to ensure the electrical connection between the first electrodes 21, thereby being beneficial to ensuring the performance of the display panel 100 and improving the reliability of the display panel 100. An optional embodiment provided by the present disclosure is that the length h2 of the connecting portion 50 along the first direction F1 = 12μm; another optional embodiment provided by the present disclosure is that the length h2 of the connecting portion 50 along the first direction F1 = 15μm; still another optional embodiment provided by the present disclosure is that the length h2 of the connecting portion 50 along the first direction F1 = 20μm; yet another optional embodiment provided by the present disclosure is that the length h2 of the connecting portion 50 along the first direction F1≥14μm.

[0075] It should be noted that, based on the same concept, in order to ensure the connection effect of the connecting portion 50, the length of the connecting portion 50 in the second direction F2 is h3, and h3≥10 μm. An optional implementation provided by the present disclosure is that the length h3 of the connecting portion 50 in the second direction F2 = 11 μm; another optional implementation provided by the present disclosure is that the length h3 of the connecting portion 50 in the second direction F2 = 15 μm; still another optional implementation provided by the present disclosure is that the length h3 of the connecting portion 50 in the second direction F2 = 18 μm. Yet another optional implementation provided by the present disclosure is that the length h3 of the connecting portion 50 in the second direction F2≥13 μm.

[0076] Based on the same inventive concept, the present disclosure provides a display device Figure 11 The following is a schematic diagram of a display device provided by an embodiment of the present disclosure. Please refer to Figure 11 , the display device 200 includes the display panel 100 provided by the embodiment of the present disclosure.

[0077] It should be noted that for the embodiments of the display device 200 provided in the embodiments of the present application, reference may be made to the embodiments of the above display panel 100, and repeated descriptions will not be elaborated. The display device 200 provided by the present application may be: a mobile phone, a tablet computer, a television, a touch controller, a notebook computer, a navigator, or any other product and component with a touch function.

[0078] As can be seen from the above embodiments, the display panel and the display device provided by the present disclosure achieve at least the following beneficial effects:

[0079] The present disclosure provides a display panel and a display device. The display device includes the display panel. The display panel includes a plurality of pixels arranged in an array, a plurality of touch units, a first touch trace, and a first scan line. The first touch trace extends in a first direction and is electrically connected to the touch units. The first scan line extends in a second direction and is located between adjacent pixel rows along the first direction. The touch unit includes a plurality of first electrodes. The display panel further includes a connection portion for electrically connecting the first electrodes. The connection portion includes a first connection portion for electrically connecting the first electrodes adjacent along the second direction. The present disclosure sets at least a part of the orthographic projection of the first connection portion on the display panel not to overlap with the orthographic projection of the first scan line on the display panel. Thus, the overlap between the first connection portion and the first scan line is reduced, thereby reducing the coupling capacitance between the first connection portion and the first scan line, which is beneficial to reducing the influence of the coupling capacitance on the potential of the touch unit. When the touch unit is multiplexed as a common electrode for driving the liquid crystal to deflect and make the pixel emit light, the influence of the coupling capacitance on the potential of the common electrode is reduced, thereby reducing the influence on the voltage difference between the common electrode and the pixel electrode, which is beneficial to improving the display effect. At the same time, for two adjacent touch units along the first direction, the coupling capacitance corresponding to at least one row of pixels in one touch unit close to the other touch unit is reduced, reducing the influence on the display effect, improving the display difference of the display panel, being beneficial to improving the slit phenomenon caused by the coupling capacitance, and thus being beneficial to improving the display effect of the display panel.
