[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0050] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0051] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual proportions, and are only intended to illustrate the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0052] In the related art, a hole is dug in the display area of ​​the display panel to place the camera. However, when the opening is set in the display area, some data lines need to be bent and wound around the opening, which increases the length of the data line and the parasitic capacitance. The voltage loaded on the data line is divided into a data writing stage and a floating stage. The voltage on the data line in the floating stage lasts until the next data writing stage starts. The voltage on the data line in the floating stage is easily interfered by other jumping signals. If the parasitic capacitance on the adjacent data lines is too large, the voltage jump on any data line will cause the voltage jump on the adjacent data line. If the data line is coupled while the row scan signal is at a low level, the sub-pixel will also be affected by the coupling, resulting in uneven brightness of the sub-pixel, and poor display of bright stripes is likely to occur, affecting the user experience.

[0053] The present disclosure provides a display panel. Figure 1 , Figure 2 , Figure 3 As shown, the display panel includes:

[0054] The base substrate 1 comprises: at least one hole area HL, a display area AA surrounding the at least one hole area HL, and a peripheral area NA surrounding the display area AA; the hole area HL comprises: a light-transmitting area HL1 and a wiring area HL2 located between the display area AA and the light-transmitting area HL1;

[0055] A plurality of data lines 2, at least located in the display area AA; the plurality of data lines 2: including a plurality of first data lines 201; the orthographic projections of the plurality of first data lines 201 on the substrate 1 do not overlap with the light-transmitting area HL1, the first data lines 201 include a first routing portion 3, the orthographic projections of at least a portion of the first routing portion 3 of the first data lines 201 on the substrate 1 pass through the wiring area HL2, and at least a portion of the first routing portion 3 of the first data lines 201 extend non-linearly; that is, the first data lines 201 are data lines 2 located near the light-transmitting area HL1, and at least a portion of the first data lines 201 need to be provided with a non-linearly extending first routing portion 3 to avoid the light-transmitting area HL1 of the hole area HL; a portion of the first routing portion 3 in the plurality of first data lines 201 includes a first sub-routing 301, and a portion of the first routing portion 3 in the plurality of first data lines 201 includes a second sub-routing 302 located at a different layer from the first sub-routing 301;

[0056] Among them, Figure 2 As shown, the orthographic projections of the first sub-routing 301 and the second sub-routing 302 on the base substrate 1 are alternately arranged, and the display panel further includes a plurality of shielding structures 4, the orthographic projections of the shielding structures 4 on the base substrate 1 overlap with the orthographic projections of the first sub-routing 301 and / or the second sub-routing 302 on the base substrate 1, and the shielding structures 4 are located in the film layer between the first sub-routing 301 and the second sub-routing 302; or, as Figure 3 As shown, at least a portion of the orthographic projections of the plurality of first sub-routes 301 on the substrate 1 are located on a side of at least a portion of the orthographic projections of the plurality of second sub-routes 302 on the substrate 1 that faces toward or away from the light-transmitting area HL1 .

[0057] It should be noted that Figure 1 In the description, the hole area HL is rectangular and the light-transmitting area HL1 is circular, and the center of the rectangle coincides with the center of the circle. In a specific implementation, the hole area HL and the light-transmitting area HL1 may both be circular, and the centers of the two circles coincide. Figure 2 For a Figure 1 A magnified schematic diagram of the E1 region in the middle. Figure 3 For another including Figure 1 Schematic diagram of the enlarged E1 region. Figure 2 For example, the first wiring portion 3 located in the wiring area HL2 closest to the display area AA extends in a straight line, and the other first wiring portions 3 extend in a non-straight line. Figure 3 The following description is made by taking the example that the first wiring portions 3 located in the wiring area HL2 all extend in a non-linear manner.

[0058] In the display panel provided by the embodiment of the present disclosure, when the first sub-route and the second sub-route are arranged alternately, a shielding structure of the film layer between the first sub-route and the second sub-route is provided, and the orthographic projection of the shielding structure on the substrate substrate overlaps with the orthographic projection of at least one of the first sub-route and the second sub-route on the substrate substrate, thereby reducing the parasitic capacitance between the first sub-route and the second sub-route. Alternatively, at least part of the orthographic projection of the plurality of first sub-routes on the substrate substrate is located on the side of at least part of the orthographic projection of the plurality of second sub-routes on the substrate substrate facing or away from the light-transmitting area, so that the first sub-route and the second sub-route are no longer arranged alternately, and the parasitic capacitance between the first sub-route and the second sub-route can be reduced. Since the parasitic capacitance between the first sub-route and the second sub-route is reduced, the voltage jump on the first data line can be reduced, and the poor display of bright stripes caused by uneven brightness can be avoided, thereby improving the display effect and user experience.

[0059] In addition, in the display panel provided by the embodiment of the present disclosure, since the wiring space in the wiring area is small, the multiple first data lines include parts located in different layers. When the first sub-routes and the second sub-routes located in different layers are arranged alternately, it is beneficial to reduce the distance between adjacent first data lines while avoiding short circuits between adjacent first data lines, thereby saving wiring space.

[0099] Next, an embodiment of setting a shielding structure is described in detail.

[0100] In some embodiments, Figure 7 to Figure 9 As shown, a plurality of shielding structures 4 are arranged on the same layer, and the orthographic projection of the shielding structure 4 on the substrate 1 covers the orthographic projection of the first sub-line 301 or the second sub-line 302 on the substrate 1 .

[0101] It should be noted that Figure 7 to Figure 9 For different Figure 2 Schematic diagram of the cross-sectional structure of FF'. Figure 7 , Figure 8 In the embodiment, the orthographic projections of the plurality of shielding structures 4 on the substrate 1 cover the orthographic projections of the second sub-line 302 on the substrate 1. Fig. 9 In the embodiment, the orthographic projections of the plurality of shielding structures 4 on the substrate 1 cover the orthographic projections of the first sub-routing 301 on the substrate 1 .

[0102] Or, in some embodiments, Fig.10 , Fig.11 As shown, the multiple shielding structures 4 include: multiple first shielding structures 401 arranged in the same layer, and multiple second shielding structures 402 arranged in the same layer and located in different layers from the first shielding structures 401;

[0103] The orthographic projection of the first shielding structure 401 on the substrate 1 covers the orthographic projection of the first sub-line 301 on the substrate 1 , and the orthographic projection of the second shielding structure 402 on the substrate 1 covers the orthographic projection of the second sub-line 302 on the substrate 1 .

[0104] It should be noted that Figure 10-11 Also for different species Figure 2 Schematic diagram of the cross-sectional structure of FF'.

[0105] In the display panel provided by the embodiment of the present disclosure, the orthographic projections of the first sub-route and the second sub-route on the base substrate are covered by the orthographic projection of the shielding structure on the base substrate, which can improve the shielding effect of the shielding structure on the first sub-route and the second sub-route, and can further reduce the parasitic capacitance between adjacent data lines.

[0106] In some embodiments, Fig.10 As shown, the second sub-line 302 is located on a side of the first sub-line 301 away from the substrate 1 , and the first shielding structure 401 is located on a side of the second shielding structure 402 away from the substrate 1 .

[0107] Or, in some embodiments, Fig.11 As shown, the second sub-line 302 is located on a side of the first sub-line 301 away from the substrate 1 , and the second shielding structure 402 is located on a side of the first shielding structure 401 away from the substrate 1 .

[0108] In some embodiments, Figure 7 to Figure 11 As shown, the plurality of first sub-routes 301 are all located in the first conductive layer 11, the plurality of second sub-routes 302 are all located in the fourth conductive layer 14, and the second conductive layer 12 and / or the third conductive layer 13 further include a shielding structure 4. Figure 7 The middle shielding structures 4 are all located in the third conductive layer 13; Figure 8 , Fig. 9 The middle shielding structures 4 are all located in the second conductive layer 12; Fig.10 In the embodiment, the first shielding structure 401 is located in the third conductive layer 13, and the second shielding structure 402 is located in the second conductive layer 12; Fig.11 In the embodiment, the second shielding structure 402 is located in the third conductive layer 13 , and the first shielding structure 401 is located in the second conductive layer 12 .

[0109] In some embodiments, when the portion of the data line located in the display area is located in the fourth conductive layer, that is, the first sub-line of the data line located in the first conductive layer needs to be electrically connected to the portion of the data line located in the fourth conductive layer. Figure 2 In the figure, for the first routing portion 3 located in the wiring area HL2, the thick line represents the portion of the first routing portion 3 located in the first conductive layer (not shown), the thin line represents the portion of the first routing portion 3 located in the fourth conductive layer (not shown), and the straight or broken line portions electrically connected at both ends of the arc-shaped portion of the first routing portion 3 that extends non-straight or has an arc-like contour are located in the fourth conductive layer (not shown) and / or the first conductive layer (not shown). In the wiring area HL2, in the orthographic projection of the substrate 1, there are two first routing portions 3 that overlap, and in the overlapping area, one of the two first routing portions 3 is located in the fourth conductive layer (not shown) and the other is located in the first conductive layer (not shown). Specifically, as Figure 2 As shown, the first routing portion 3 also includes a third sub-routing 303 and a fourth sub-routing 304 which are electrically connected to both ends of the first sub-routing 301 or the second sub-routing 302 respectively; the third sub-routing 303 is located in the fourth conductive layer (not shown) and / or the first conductive layer (not shown), and the fourth sub-routing 304 is located in the fourth conductive layer (not shown) and / or the first conductive layer (not shown).

[0110] In some embodiments, Fig. 9 As shown, the minimum distance h1 between the surface 25 of at least part of the shielding structure 4 on the side close to the substrate substrate 1 and the substrate substrate 1 is smaller than the distance h2 between the surface 26 of the first sub-route 301 on the side away from the substrate substrate 1 and the substrate substrate 1; and the surface 25 of at least part of the shielding structure 4 on the side close to the substrate substrate 1 has a groove 24 that is recessed toward the side away from the substrate substrate 1, and the orthographic projection of the first sub-route 301 on the substrate substrate 1 is located within the orthographic projection of the groove 24 on the substrate substrate 1.

[0111] That is, in the display panel provided by the embodiment of the present disclosure, at least part of the shielding structure covers part of the side surface of the first sub-line, thereby further improving the shielding effect of the shielding structure and reducing the parasitic capacitance between adjacent data lines.

[0112] It should be noted that Fig. 9In the specific implementation, when the shielding structure includes a first shielding structure and a second shielding structure, the first shielding structure covers the first sub-line and the first shielding structure is located in the second conductive layer. Fig. 9 How to set it up.

[0113] It should be noted that if m=4, n=1, and the first sub-route and the second sub-route are alternately arranged in the wiring area, the voltage jump of the data line electrically connected to the red sub-pixel will couple the data line electrically connected to the green sub-pixel. When the driving order of MUX is MUX2, MUX1, MUX4, and MUX3, the data line electrically connected to the green sub-pixel is coupled the most times, and green vertical stripes will appear in the display area below the hole area. The display panel provided by the embodiment of the present disclosure can reduce the parasitic capacitance between the data lines by setting a shielding structure, which can alleviate the poor display of green vertical stripes.

[0114] It should be noted that although Figure 2 Taking m=4 and n=1 as an example, for a multiplexer circuit with m=2 and n=1, the first sub-routing and the second sub-routing can still be alternately arranged in the wiring area, and a shielding structure can be arranged. The setting method of the shielding structure is the same as the above. Figure 7 to Figure 11 The setting method is the same and will not be repeated here.

[0115] Next, Figure 7 to Figure 10 Taking the structure shown in FIG. 1 as an example, the parasitic capacitance between the data lines provided by the embodiment of the present disclosure is described. The capacitance data per unit length (100 μm) is shown in Table 1, where N1 is a display panel without a shielding layer and having bright streaks, and N2, N3, N4, and N5 are respectively Figure 7 to Figure 10 In the structure shown, c1 represents the parasitic capacitance between the closest second sub-routing 302 located in the same layer, c2 represents the parasitic capacitance between the closest first sub-routing 301 located in the same layer, c3 represents the parasitic capacitance between the adjacent first sub-routing 301 and the second sub-routing 302, the total capacitance 1 represents the capacitance of the portion of the data line located in the fourth conductive layer, and the total capacitance 2 represents the capacitance of the portion of the data line located in the first conductive layer. The units of the above capacitances are all femtofarads (fF) / 100 micrometers (μm). It can be seen from Table 1 that the parasitic capacitances of c1, c2, and c3 of N2, N3, N4, and N5 are all reduced compared to N1. It is known that the display panel corresponding to N2 is already a qualified product without bright streak defects, and the parasitic capacitances of c1, c2, and c3 of the display panel corresponding to N5 are the most reduced compared to N2, that is, setting a double-layer shielding structure can better improve the parasitic capacitance between data lines.

[0125] It should be noted that Fig.12 , Fig.13The circuit structure of the pixel unit of the present disclosure is merely an example. In a specific implementation, the pixel unit may also include other numbers of thin film transistors and capacitors. The circuit structure of the pixel unit may also be applicable to low temperature polycrystalline oxide (LTPO) circuits, etc. The number of thin film transistors and capacitors, the device type of thin film transistors, the connection relationship, etc. are not limited here.

[0126] Next, an embodiment in which at least a portion of the orthographic projections of the plurality of first sub-routes on the substrate are located on a side of at least a portion of the orthographic projections of the plurality of second sub-routes on the substrate facing toward or away from the light-transmitting region is described in detail.

[0127] In some embodiments, Figure 3 As shown, the wiring area HL2 includes: a first wiring area HL201 surrounding the light-transmitting area HL1, and a second wiring area HL202 surrounding the first wiring area HL201 on a side of the first wiring area HL201 away from the light-transmitting area HL1.

[0128] In some embodiments, Figure 3 As shown, at least part of the orthographic projection of the plurality of first sub-routes 301 on the substrate 1 is located in the first wiring area HL201 , and at least part of the orthographic projection of the plurality of second sub-routes 302 on the substrate 1 is located in the second wiring area HL202 .

[0129] Alternatively, in some embodiments, at least part of the orthographic projection of the plurality of first sub-routes 301 on the substrate 1 is located in the first wiring area HL201 , and at least part of the orthographic projection of the plurality of second sub-routes 302 on the substrate 1 is located in the second wiring area HL202 .

[0130] In some embodiments, Figure 3 As shown, among the first data lines 201 electrically connected to any two adjacent sub-pixel columns 7 , one of the first data lines 201 includes a first sub-wire 301 , and the other first data line 201 includes a second sub-wire 302 .

[0131] In some embodiments, Figure 3 As shown, among any two adjacent first data lines 201 in the display area AA, one of the first data lines 201 includes a first sub-routing line 301, and the other first data line 201 includes a second sub-routing line 302. Therefore, the first routing portions 3 corresponding to any two adjacent first data lines 201 in the display area AA are respectively located in the first wiring area HL201 and the second wiring area HL202, and the distance between the two is relatively far, which can avoid mutual interference between the first sub-routing lines 301 and the second sub-routing lines 302 corresponding to the two, resulting in excessive parasitic capacitance and causing poor bright lines.

[0132] In some embodiments, Fig.14 As shown, a plurality of first sub-routes 301 are located in different layers, and any two adjacent first sub-routes 301 are located in different layers; that is, the first sub-routes 301 located in different layers are arranged alternately in the orthographic projection of the substrate, and even if the distance between the first sub-routes 301 is reduced, there will be no short circuit problem between the two, which can save wiring space;

[0133] Multiple second sub-routes 302 are located in different layers, and any two adjacent second sub-routes 302 are located in different layers; that is, the second sub-routes 302 located in different layers are arranged alternately in the orthographic projection of the substrate. Even if the distance between the second sub-routes 302 is reduced, there will be no short circuit problem between the two, which can save wiring space.

[0134] It should be noted that Fig.14 For along Figure 3 Cross-sectional view of HH'.

[0135] In some embodiments, when part of the first sub-routing is located in the first conductive layer, the rest of the first sub-routing may be located in one of the second conductive layer, the third conductive layer, and the fourth conductive layer;

[0136] When part of the second sub-routing is located in the fourth conductive layer, the rest of the second sub-routing may be located in one of the second conductive layer, the third conductive layer and the first conductive layer.

[0137] In some embodiments, Fig.15 As shown, some of the first sub-routes 301 among the plurality of first sub-routes 301 are also located in the second conductive layer 12;

[0138] Some of the second sub-routes 302 among the plurality of second sub-routes 302 are also located in the third conductive layer 13 .

[0139] In some embodiments, Figure 3 As shown, the first routing portion 3 further includes a third sub-routing 303 and a fourth sub-routing 304 which are electrically connected to both ends of the first sub-routing 301 or the second sub-routing 302 respectively;

[0140] For the first routing portion 3 including the first sub-routing 301, the third sub-routing 303 and the fourth sub-routing 304 are arranged in the same layer as the first sub-routing 301, that is, the first sub-routing 301, the third sub-routing 303, and the fourth sub-routing 304 are all located in the first conductive layer (not shown) or the second conductive layer (not shown);

[0141] For the first routing section 3 including the second sub-routing 302, the third sub-routing 303 and the fourth sub-routing 304 are arranged on the same layer as the second sub-routing 302, and the second sub-routing 302, the third sub-routing 303, and the fourth sub-routing 304 are all located in the third conductive layer (not shown) or the fourth conductive layer (not shown).

[0142] In some embodiments, Fig.15 As shown, the display panel also includes:

[0143] The third shielding structure 5 is located at least one of the first conductive layer (not shown), the second conductive layer (not shown), the third conductive layer 13, and the fourth conductive layer (not shown); at least a partial area of ​​the orthographic projection of the third shielding structure 5 on the substrate substrate 1 is located in the wiring area HL2 between the orthographic projection of multiple first sub-routes 301 on the substrate substrate 1 and the orthographic projection of multiple second sub-routes 302 on the substrate substrate 1.

[0144] The display panel provided by the embodiment of the present disclosure further provides a third shielding structure between the plurality of first sub-routes and the plurality of second sub-routes, so as to avoid mutual interference between the two most adjacent first sub-routes and the second sub-routes.

[0145] In some embodiments, Fig.15 The third shielding structure 5 is located in the third conductive layer 13 as an example for illustration.

[0146] In some embodiments, Fig.15 As shown, when the first sub-route 301 is located in the first wiring area HL201, the third sub-route 303 electrically connected to the first sub-route 301 extends from the first wiring area HL201 to the second wiring area HL202, and the orthographic projection of the third sub-route 303 electrically connected to the first sub-route 301 on the substrate substrate 1 overlaps with the orthographic projection of the third shielding structure 5 on the substrate substrate 1, therefore, the third shielding structure 5 needs to be located in a different layer from the third sub-route 303 electrically connected to the first sub-route 301. Similarly, if the second sub-route is located in the first wiring area, the third sub-route electrically connected to the second sub-route extends from the first wiring area to the second wiring area, and the orthographic projection of the third sub-route electrically connected to the second sub-route on the substrate substrate overlaps with the orthographic projection of the third shielding structure on the substrate substrate, the third shielding structure needs to be located in a different layer from the third sub-route electrically connected to the second sub-route.

[0147] In some embodiments, a line width of the third shielding structure is greater than a line width of the data line.

[0148] In some embodiments, the third shielding structure inputs a constant voltage signal.

[0149] In some embodiments, Fig.12The third shielding structure can be electrically connected to one of the first level signal line VSS, the power supply voltage signal line VDD, and the initialization signal line VINT.

[0150] Based on the same inventive concept, an embodiment of the present disclosure further provides a display device, including the display panel provided by the embodiment of the present disclosure.

The implementation of the display device can refer to the embodiment of the display panel above, and the repeated parts will not be described in detail.

[0152] In summary, in the display panel and display device provided by the embodiments of the present disclosure, when the first sub-routing and the second sub-routing are arranged alternately, a shielding structure of the film layer between the first sub-routing and the second sub-routing is provided, and the orthographic projection of the shielding structure on the substrate substrate overlaps with the orthographic projection of at least one of the first sub-routing and the second sub-routing on the substrate substrate, thereby reducing the parasitic capacitance between the first sub-routing and the second sub-routing. Alternatively, at least a portion of the orthographic projection of the plurality of first sub-routing on the substrate substrate is located on the side of at least a portion of the orthographic projection of the plurality of second sub-routing on the substrate substrate facing or away from the light-transmitting area, so that the first sub-routing and the second sub-routing are no longer arranged alternately, and the parasitic capacitance between the first sub-routing and the second sub-routing can be reduced. Since the parasitic capacitance between the first sub-routing and the second sub-routing is reduced, the voltage jump on the first data line can be reduced, and the poor display of bright stripes caused by uneven brightness can be avoided, thereby improving the display effect and user experience.
