[0038] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0039] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0040] First, refer to Figure 1A-Figure 4 As shown, an embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display panel 10 (Organic Light Emitting Diode, referred to as OLED) or a quantum dot electroluminescent display panel 10 (Quantum Dot Light Emitting Diodes, referred to as QLED).

[0041] Specifically, the display panel 10 includes an opening area 10a, a display area 10b and a first non-display area 10c, the display area 10b surrounds the first non-display area 10c, and the first non-display area 10c surrounds the opening area 10a. It can be understood that the display panel 10 also includes a second non-display area (not shown), and the second non-display area is arranged around the display area 10b.

[0042] Furthermore, the display panel 10 further includes a substrate 11, a first shielding portion 12 and a constant voltage signal line 13. The first shielding portion 12 is located on one side of the substrate 11 and is located in the first non-display area 10c; the first shielding portion 12 at least partially surrounds the opening area 10a; the constant voltage signal line 13 is located on one side of the substrate 11 and is located on the side of the first non-display area 10c away from the opening area 10a; the first shielding portion 12 is electrically connected to the constant voltage signal line 13. It should be noted that the constant voltage signal line 13 can be a ground signal line (GND), a positive voltage power supply signal line, a negative voltage power supply signal line, etc. The first shielding portion 12 can be arranged around at least part of the periphery of the opening area 10a, or around the entire periphery of the opening area 10a, such as the first shielding portion 12 can be a ring structure.

[0043] It is understandable that the substrate 11 may be a flexible substrate, such as a polyimide (PI) substrate, a polyethylene terephthalate (PET) substrate or a polymethyl methacrylate (PMMA) substrate. The substrate 11 may also be a rigid substrate, such as glass.

[0044] The display panel 10 provided in the embodiment of the present application is provided with a first shielding portion 12 in the first non-display area 10c, so that at least a portion of the first shielding portion 12 surrounds the opening area 10a, and the first shielding portion 12 is electrically connected to the constant voltage signal line 13. In this way, the first shielding portion 12 can shield and conduct static electricity near the opening area 10a, thereby improving the anti-ESD performance of the display panel 10, improving the problem of static electricity loss in the opening area 10a, and facilitating the improvement of product yield.

[0045] In one embodiment, in combination Figure 2 and Figure 3A As shown, the display area 10b includes a plurality of scan signal lines 1151 arranged along a first direction X and a plurality of data signal lines 1152 arranged along a second direction Y. Each scan signal line 1151 extends along the second direction Y, and each data signal line 1152 extends along the first direction X. The first direction X intersects the second direction Y, and in particular, the first direction X is perpendicular to the second direction Y.

[0046] The first non-display area 10c includes a first sub-non-display area 10c1 and a second sub-non-display area 10c2. The first sub-non-display area 10c1 is located between the display area 10b and the second sub-non-display area 10c2. The second sub-non-display area 10c2 is located between the first sub-non-display area 10c1 and the opening area 10a.

[0047] The first sub non-display area 10c1 includes a plurality of first signal lines 1153 and a plurality of second signal lines 1154. The first signal lines 1153 include a first sub-signal line 1153-1 and a second sub-signal line 1153-2 located on both sides of the opening area 10a along the second direction Y. The first sub-signal line 1153-1 extends along the first direction X, and the second sub-signal line 1153-2 extends along the first direction X. The first sub-signal line 1153-1 and the second sub-signal line 1153-2 are electrically connected to the data signal line 1152. Figure 2 For example, the first sub-signal line 1153-1 is located on the right side of the opening area 10a, and the second sub-signal line 1153-2 is located on the left side of the opening area 10a. The second sub-non-display area 10c2 includes a plurality of third signal lines 1155 and a plurality of fourth signal lines 1156; along the second direction Y, the second signal lines 1154 and the third signal lines 1155 are electrically connected to the scanning signal lines 1151; along the first direction X, the fourth signal lines 1156 are located between at least part of the third signal lines 1155, and the first shielding portion 12 is located in the second sub-non-display area 10c2.

[0048] It can be understood that the first sub-non-display area 10c1 has more metal wiring, which is provided with both the bypass hole connection line of the data line and the bypass hole connection line of the scan line, so the first sub-non-display area 10c1 has less wiring space. On the contrary, the second sub-non-display area 10c2 is only provided with the bypass hole connection line of some scan lines, and has more space for wiring. By setting the first shielding part 12 in the second sub-non-display area 10c2, on the one hand, the adapter line between the constant voltage signal line 13 and the first shielding part 12 can be flexibly set to reduce the frame of the display panel. At the same time, since the second sub-non-display area 10c2 is closer to the opening area 10a, its static electricity shielding effect is better.

[0049] Reference Figure 1B As shown, the display panel 10 includes a semiconductor layer 116, a first insulating layer 110, a first metal layer 14, a second insulating layer 111, a second metal layer 15, a third insulating layer 112, a third metal layer 16, a fourth insulating layer 113, an anode layer 19, a light-emitting layer 117 and a cathode layer 18, which are sequentially stacked on a substrate 11. Among them, the semiconductor layer 116, the first insulating layer 110, the first metal layer 14, the second insulating layer 111, the second metal layer 15, the third insulating layer 112 and the third metal layer 16 together constitute a driving structure layer, and the driving transistor, capacitor and wiring of the pixel circuit are arranged in the driving structure layer. It should be noted that the first metal layer 14 is a gate metal layer, the second metal layer 15 is a capacitor metal layer, the third metal layer 16 is a source and drain metal layer, the first insulating layer 110 is a gate insulating layer, the second insulating layer 111 is a capacitor insulating layer, and the third insulating layer 112 is an interlayer dielectric layer. The first signal line 1153 and the data signal line 1152 are located in the third metal layer 16 , and the second signal line 1154 , the third signal line 1155 and the scan signal line 1151 are located in the first metal layer 14 and / or the second metal layer 15 .

[0050] In one embodiment, reference Figure 2 , Figure 3A and Figure 4 , the edge of the display panel is encapsulated with encapsulation glue to prevent the external water and oxygen from causing the encapsulation failure of the display panel. The encapsulation glue 17 is located in the second sub-non-display area 10c2. The frame sealant of the display panel is generally glass frit, and its encapsulation curing process requires laser melting and sintering. The fourth signal line 1156 is in a floating state, that is, the fourth signal line 1156 is not connected to any voltage signal. On the one hand, the fourth signal line 1156 is a dummy wiring. The fourth signal line 1156 is a metal wiring and is located below the encapsulation glue 17. It can make a part of the laser be reflected by the fourth signal line 1156 when the laser is irradiated, so that the energy utilization rate of the laser is improved and the energy consumption during packaging is reduced; on the other hand, the fourth signal line 1156 can also ensure the uniformity of the process etching of each area of ​​the display panel 10.

[0051] The first connection line 1157 is located in the first sub-non-display area 10c1, and the first connection line 1157 is electrically connected to the constant voltage signal line 13. Exemplarily, the first connection line 1157 may be located in the third metal layer or in other metal layers away from the substrate on the third metal layer. Exemplarily, the constant voltage signal line 13 may be a reference voltage line Vref near the opening area or a power signal line PVDD or a bias voltage line DVH, etc., or may be a power signal PVEE of the cathode layer 18, etc. The first shielding part 12 is electrically connected to the first connecting line 1157. In a direction perpendicular to the plane where the substrate is located, the first shielding part 12 at least partially overlaps with the packaging glue 17. On the one hand, the first shielding part 12 receives a constant voltage signal to shield and guide the static electricity near the opening area 10a, thereby improving the anti-ESD performance of the display panel 10 and improving the problem of static electricity loss in the opening area 10a. On the other hand, the first shielding part 12 can be further reused as a packaging metal layer, that is, the bottom of the packaging glue 17 includes not only the third signal line 1155 and the plurality of fourth signal lines 1156, but also the first shielding part 12, which can further improve the sintering efficiency of the packaging glue 17. Furthermore, in one embodiment, as Figure 4 As shown, the first connection line 1157 is located in the third metal layer 16. In this way, the first connection line 1157, the first shielding portion 12 and the first signal line 1153 can be manufactured in the same process, which is beneficial to reduce the manufacturing cost.

[0052] Please refer to Figure 3B , Figure 3B for Figure 2 A local color schematic diagram of the A region. Figure 3B In the figure, the green film layer represents the first metal layer 14 (i.e., the gate metal layer), the blue film layer represents the second metal layer 15 (i.e., the capacitor metal layer), and the orange film layer represents the third metal layer 16 (i.e., the source and drain metal layer). Figure 3B It can be seen that a part of the second signal lines 1154 are located in the first metal layer 14, another part of the second signal lines 1154 are located in the second metal layer 15, a part of the third signal lines 1155 are located in the first metal layer 14, another part of the third signal lines 1155 are located in the second metal layer 15, a part of the fourth signal lines 1156 are located in the first metal layer 14, and another part of the fourth signal lines 1156 are located in the second metal layer 15.

[0053] In one embodiment, referring to Figure 5 , Figure 6 and Figure 7As shown, the fourth signal line 1156 also includes multiple fourth sub-signal lines 1156-1, the first sub-non-display area 10c1 also includes multiple first connecting lines 1157, the first connecting lines 1157 are electrically connected to the constant voltage signal line 13, at least part of the fourth sub-signal lines 1156-1 are electrically connected to the first connecting lines 1157, and the first shielding portion 12 is electrically connected to the fourth sub-signal line 1156-1.

[0054] In this way, at least part of the fourth signal line 1156 is equivalent to being used as a routing line for connecting the constant voltage signal line 13 with the first shielding part 12, thus reducing the difficulty of setting the routing line, thereby facilitating the connection of the first shielding part 12 with the constant voltage signal line 13. In addition, a part of the fourth signal line 1156 is reused as a routing line for transmitting the shielding signal, thereby eliminating the need to add new routing lines and reducing the difficulty of process manufacturing.

[0055] In one embodiment, referring to Figure 6 and Figure 7 As shown, the display panel 10 further includes a first metal layer 14, a second metal layer 15, a third metal layer 16, a first connection line 1157 and a packaging glue 17. The first metal layer 14 is located on one side of the substrate 11; the second metal layer 15 is located on the side of the first metal layer 14 away from the substrate 11; the third metal layer 16 is located on the side of the second metal layer 15 away from the substrate 11; the first connection line 1157 is located in the first sub-non-display area 10c1, one end of the first connection line 1157 is electrically connected to the constant voltage signal line 13, and the other end of the first connection line 1157 is electrically connected to the fourth sub-signal line 1156-1. The packaging glue 17 is located in the second sub-non-display area 10c2. Among them, the first metal layer 14 is a gate metal layer, the second metal layer 15 is a capacitor metal layer, and the third metal layer 16 is a source and drain metal layer. The film layers where the second signal line 1154, the third signal line 1155, and the fourth signal line 1156 are located are all the first metal layer 14 and / or the second metal layer 15, and the film layers where the first signal line 1153 and the first shielding portion 12 are located are all the third metal layer 16. Furthermore, the first connecting line 1157 is located in the third metal layer 16, and the constant voltage signal line 13 is located on the side of the third metal layer 16 away from the substrate 11.

[0056] By setting the first connection line 1157 in the third metal layer 16, the film layer structure between the first connection line 1157 and the constant voltage signal line 13 can be reduced, which is convenient for connecting the two. In addition, the first connection line 1157, the first signal line 1153 and the first shielding part 12 are all located in the same film layer and can be manufactured in the same process, thereby reducing the manufacturing cost. Since the first signal line 1153 is provided between the first connection line 1157 and the first shielding part 12, the fourth sub-signal line 1156-1 can cross the first signal line 1153 to connect the first connection line 1157 and the first shielding part 12.

[0057] In an example, a portion of the second signal lines 1154 are located in the first metal layer 14, another portion of the second signal lines 1154 are located in the second metal layer 15, a portion of the third signal lines 1155 are located in the first metal layer 14, another portion of the third signal lines 1155 are located in the second metal layer 15, a portion of the fourth signal lines 1156 are located in the first metal layer 14, and another portion of the fourth signal lines 1156 are located in the second metal layer 15.

[0058] In one embodiment, referring to Fig.12 , Fig.13 and Fig.14 As shown, the first shielding portion 12 includes a first shielding sub-portion 121 and a second shielding sub-portion 122. Along the second direction Y, the first shielding sub-portion 121, the fourth sub-signal line 1156-1 and the second shielding sub-portion 122 are electrically connected. Along the direction perpendicular to the plane where the substrate 11 is located, the first shielding sub-portion 121 and the second shielding sub-portion 122 have no overlap with the packaging glue 17.

[0059] Here, it should be noted that the first shielding sub-portion 121 is metal, and after the packaging glue 17 is in direct contact with the metal, the connection stability between the two is insufficient. In this embodiment, by making the first shielding sub-portion 121 and the second shielding sub-portion 122 not overlap with the packaging glue 17 in the vertical direction (the thickness direction of the display panel 10), the first shielding portion 12 can be prevented from contacting the packaging glue 17, and the first shielding portion 12 is in contact with the non-metallic film layer, which is conducive to improving the connection stability of the packaging glue 17 and the packaging reliability.

[0060] In one example, referring to Figure 6 and Figure 7 As shown, along the direction perpendicular to the plane where the substrate 11 is located, part of the first shielding part 12 overlaps with the packaging glue 17. Specifically, the first shielding part 12 includes a shielding ring (not shown) and a connecting part (not shown), the shielding ring is arranged around the opening area 10a, the connecting part is strip-shaped, the connecting part is arranged on the side of the shielding ring away from the opening area 10a, and is connected to the fourth sub-signal line 1156-1. In this way, less of the first shielding part 12 can be in contact with the packaging glue 17, which is conducive to improving the connection stability and packaging reliability of the packaging glue 17. Furthermore, the orthographic projection of the fourth sub-signal line 1156-1 on the substrate 11 has an overlapping area with the orthographic projection of the first signal line 1153 on the substrate 11.

[0061] In another example, referring to Figure 8 , Fig. 9 and Fig.10As shown, the first shielding portion 12 includes a first shielding sub-portion 121 and a second shielding sub-portion 122. Along the direction perpendicular to the plane where the substrate 11 is located, the first shielding sub-portion 121 and the second shielding sub-portion 122 have no overlap with the packaging glue 17. The first shielding sub-portion 121 is located on the side of the packaging glue 17 close to the opening area 10a, and the second shielding sub-portion 122 is located on the side of the packaging glue 17 away from the hole area 10a. The first shielding sub-portion 121 and the second shielding sub-portion 122 are both annular and are both arranged around the outer periphery of the opening area 10a. Further, the first shielding portion 12 also includes a connecting portion (not shown in the figure), which is in the shape of a strip, and the connecting portion connects the first shielding sub-portion 121 and the second shielding sub-portion 122, and the fourth sub-signal line 1156-1 is connected to the second shielding sub-portion 122. It can be understood that, as Fig.11 As shown, the second shielding sub-portion 122 may also be directly electrically connected to the first connecting line 1157 .

[0062] In one embodiment, referring to Fig.15 As shown, the display panel 10 further includes a first metal layer 14, a second metal layer 15, a third metal layer 16, a packaging glue 17, and a first connection line 1157. The first metal layer 14 is located on one side of the substrate 11. The second metal layer 15 is located on a side of the first metal layer 14 away from the substrate 11. The third metal layer 16 is located on a side of the second metal layer 15 away from the substrate 11. The packaging glue 17 is located in the second sub non-display area 10c2. The first connection line 1157 is located in the first sub non-display area 10c1, and the first connection line 1157 is electrically connected to the fourth sub signal line 1156-1. The film layers where the second signal line 1154, the third signal line 1155, the fourth signal line 1156 and the first shielding part 12 are located are all the first metal layer 14 and / or the second metal layer 15, and the film layers where the first signal line 1153 is located are all the third metal layer 16; along the plane direction perpendicular to the substrate 11, the first shielding part 12 and the packaging glue 17 do not overlap, and the first shielding part 12 is located between the packaging area where the packaging glue 17 is located and the opening area 10a. Among them, the first metal layer 14 is a gate metal layer, the second metal layer 15 is a capacitor metal layer, and the third metal layer 16 is a source and drain metal layer.

[0063] In this way, by setting the first shielding part 12 between the packaging area where the packaging glue 17 is located and the opening area 10a, on the one hand, the first shielding part 12 can be closer to the opening area 10a, which helps to improve the shielding performance; on the other hand, it can prevent the first shielding part 12 from contacting the packaging glue 17, which is conducive to improving the connection stability and packaging reliability of the packaging glue 17. Furthermore, the first connecting line 1157 is located in the third metal layer 16, and the constant voltage signal line 13 is located on the side of the third metal layer 16 away from the substrate 11. By setting the first connecting line 1157 in the third metal layer 16, the film layer structure between the first connecting line 1157 and the constant voltage signal line 13 can be reduced, which is convenient for connecting the two. In addition, the first connecting line 1157, the first signal line 1153 and the first shielding part 12 are all located in the same film layer and can be manufactured in the same process, reducing the manufacturing cost. Since the first signal line 1153 is disposed between the first connection line 1157 and the first shielding portion 12 , the fourth sub-signal line 1156 - 1 can cross the first signal line 1153 to connect the first connection line 1157 and the first shielding portion 12 .

[0064] In one embodiment, referring to Fig.16 , Fig.17 and Fig.18 As shown, the first shielding part 12 includes a first shielding sub-part 121 and a second shielding sub-part 122, the fourth sub-signal line 1156-1 connects the first shielding sub-part 121 and the second shielding sub-part 122, and the second shielding sub-part 122 is electrically connected to the constant voltage signal line 13. In the direction perpendicular to the plane where the substrate 11 is located, the first shielding sub-part 121 and the second shielding sub-part 122 are not overlapped with the packaging glue 17. In this way, the electrical connection between the first shielding part 12 and the constant voltage signal line 13 can be achieved without setting the first connecting line 1157, thereby reducing the routing and facilitating etching uniformity.

[0065] In one embodiment, the first shielding portion 12 includes m shielding sub-portions electrically connected to each other, and any one of the m shielding sub-portions and any one of the metal layers in the array layer of the display panel 10 are located in the same film layer, where m is an integer and m≥2. In this way, by providing multiple shielding sub-portions, the shielding performance can be improved, which is conducive to further improving the protection performance against static electricity.

[0066] In a specific embodiment, the orthographic projection of each shielding sub-portion on the substrate 11 is annular, and the orthographic projections of all shielding sub-portions on the substrate 11 are nested in sequence, that is, in any two adjacent shielding sub-portions, the orthographic projection of one shielding sub-portion on the substrate 11 is arranged around the periphery of the orthographic projection of the other shielding sub-portion on the substrate 11. Exemplarily, the first shielding portion 12 includes two shielding sub-portions, one shielding sub-portion is located on the third metal layer 16, and the other shielding sub-portion is located on the second metal layer 15 or the first metal layer 14.

[0067] In one embodiment, the first shielding portion 12 includes a first shielding sub-portion 121 and a second shielding sub-portion 122, and the first shielding sub-portion 121 is electrically insulated from the second shielding sub-portion 122. The constant voltage signal line 13 includes a first constant voltage signal line 13 and a second constant voltage signal line 13, and the voltage of the first constant voltage signal line 13 is different from the voltage of the second constant voltage signal line 13. The first shielding sub-portion 121 is electrically connected to the first constant voltage signal line 13, and the second shielding sub-portion 122 is electrically connected to the second constant voltage signal line 13. In this way, by connecting different signals to the first shielding sub-portion 121 and the second shielding sub-portion 122, respectively, the shielding effect of the first shielding portion 12 against static electricity can be made better. In addition, when one of the first shielding sub-portion 121 and the second shielding sub-portion 122 cannot be shielded due to a signal failure, the other can play a shielding role, thereby ensuring the shielding effect of the first shielding portion 12.

[0068] In one embodiment, the constant voltage signal line 13 is a negative power supply voltage signal line, that is, the constant voltage signal line 13 transmits a cathode signal. The cathode power supply voltage line of the display panel is generally wound around the display area in the non-display area and then overlapped with the cathode at the left and right upper frames, transmitting the cathode potential to the cathode, and the cathode layer 18 is vapor-deposited on the entire surface. In this way, by electrically connecting the cathode layer 18 near the opening area to the first shield 18 through a metal transfer, the voltage of the cathode signal is relatively stable and can be kept constant, and static electricity can be better derived and released, thereby improving the electrostatic protection capability.

[0069] In one embodiment, the display panel 10 further includes an anode layer 19 and a cathode layer 18. The anode layer 19 is located on the side of the first shielding portion 12 away from the substrate 11; the cathode layer 18 is located on the side of the anode layer 19 away from the anode layer 19; the anode layer 19 includes an anode main body located in the display area 10b and an anode transition portion 191 located in the first non-display area 10c, and the anode transition portion 191, the cathode layer 18 and the first shielding portion 12 are all electrically connected. In this way, it is equivalent to using a part of the film layer where the anode is located (the anode transition portion 191) as a routing line connecting the constant voltage signal line 13 with the first shielding portion 12, thus reducing the difficulty of setting the routing line, thereby facilitating the connection of the first shielding portion 12 with the constant voltage signal line 13.

[0070] In one embodiment, the display panel 10 further includes a first insulating layer 110, a second insulating layer 111, a third insulating layer 112, a fourth insulating layer 113 and a fifth insulating layer 114. The first insulating layer 110 is located between the first metal layer 14 and the substrate 11, the second insulating layer 111 is located between the first metal layer 14 and the second metal layer 15, the third insulating layer 112 is located between the second metal layer 15 and the third metal layer 16, the fourth insulating layer 113 is located between the third metal layer 16 and the anode layer 19, and the fifth insulating layer 114 is located between the anode layer 19 and the cathode layer 18.

[0073] The display device provided in the embodiment of the present application is provided with a first shielding portion in the first non-display area, so that at least part of the first shielding portion surrounds the opening area, and the first shielding portion is electrically connected to the constant voltage signal line. In this way, the first shielding portion can shield and guide the static electricity near the opening area, thereby improving the anti-ESD performance of the display device, improving the problem of static electricity loss in the opening area, and being conducive to improving the product yield.
