[0061] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. In the figures, the same reference numerals represent the same or similar structures, and thus their repeated description will be omitted. "or" and "or" in the specification may both mean "and" or "or".

[0062] In order to solve the problems in the prior art, an embodiment of the present invention provides a display panel, which includes an opening area, an isolation area surrounding the opening area, and a display area surrounding the isolation area, wherein the isolation area includes: a substrate; an isolation column, located on one side of the substrate; an organic functional layer, located on the side of the isolation column away from the substrate; a cathode layer, located on the side of the organic functional layer away from the substrate, and the isolation column disconnects the organic functional layer and / or the cathode layer; at least one conductive layer, located between at least part of the substrate and the isolation column, and / or on the side of at least part of the isolation column away from the substrate; wherein in the thickness direction of the substrate, the conductive layer and the orthographic projection of the isolation column at least partially overlap, and the conductive layer is electrically connected to the fixed potential line. The technical solution of the present application is to set at least one conductive layer between the isolation column and the substrate, or set at least one conductive layer on the side of the isolation column away from the substrate, or set at least one conductive layer between the isolation column and the substrate and on the side of the isolation column away from the substrate, so that static electricity can be timely conducted out of the display panel through the conductive layer, thereby improving the antistatic ability of the display panel and improving the yield rate of the display panel passing the ESD test.

[0063] The display panel provided by the embodiment of the present invention will be explained in detail below in conjunction with specific embodiments.

[0064] like Figure 1 As shown, the display panel 100 includes an opening area 11, an isolation area 12 surrounding the opening area 11, and a display area 13 surrounding the isolation area 12. Figure 2As shown, the isolation region 12 includes a substrate 1, an isolation column 2, an organic functional layer 3, a cathode layer 4 and at least one conductive layer 5. The isolation column 2 is located on one side of the substrate 1, the organic functional layer 3 is located on the side of the isolation column 2 away from the substrate 1, the cathode layer 4 is located on the side of the organic functional layer 3 away from the substrate 1, and the isolation column 2 disconnects the organic functional layer 3.

[0065] Specifically, the substrate 1 may be a flexible substrate or a rigid substrate. The material of the flexible substrate may be, for example, PI (polyimide); the material of the rigid substrate may be, for example, glass, silicon, or sapphire.

[0066] It should be noted that the substrate 1 may be a one-layer structure or a multi-layer structure. For example, the substrate 1 may include at least one flexible substrate and at least one buffer layer, and the flexible substrate and the buffer layer are alternately stacked.

[0067] The isolation column 2 is made of a metal material, and the isolation column 2 includes at least one layer. In some embodiments, the isolation column 2 includes a first sublayer, a second sublayer and a third sublayer, the second sublayer is located between the first sublayer and the second sublayer, and the width of the second sublayer is smaller than the first sublayer and / or the third sublayer. The materials of the first sublayer, the second sublayer and the third sublayer can be Ti, Al and Ti. The setting of the isolation column 2 can disconnect the organic functional layer 3 of the display area 13 and the organic functional layer 3 of the isolation area 12, and prevent the water vapor and oxygen at the cutting edge of the opening area 11 from being transmitted along the organic functional layer 3 to the display area 13, causing poor display. In other embodiments, the isolation column 2 can also disconnect the cathode layer 4.

[0068] like Figure 2 As shown, the display panel 100 includes at least one conductive layer 5, and the isolation column 2 includes a plurality of sub-isolation columns. In the thickness direction of the substrate 1, the conductive layer 5 at least partially overlaps with the orthographic projection of the sub-isolation column near the opening area 11. For example, Figure 2 As shown, the display panel 100 includes two conductive layers 5, namely a conductive layer 5 (1) and a conductive layer 5 (2), both of which are located between the substrate 1 and the isolation column 2; the isolation column 2 includes a first sub-isolation column 21 and a second sub-isolation column 22, and in the thickness direction of the substrate 1, the conductive layer 5 (1) and the conductive layer 5 (2) overlap with the positive projection of the first sub-isolation column 21 near the opening area 11.

[0069] When static electricity is transmitted, it is easiest to transmit from a position close to the opening area 11, and a conductive layer 5 that overlaps with the positive projection of the first sub-isolation column 21 is set between the first sub-isolation column 21 close to the opening area 11 and the substrate 1, and a longitudinal capacitor is formed at the overlap to absorb static electricity charge, which can increase the difficulty of static electricity conduction to the cathode layer 4, thereby reducing the amount of static electricity conducted to the cathode layer 4. Increasing the number of conductive layers 5 can increase the capacitance in the thickness direction of the substrate, increase the amount of electrostatic charge absorbed, increase the difficulty of static electricity conduction to the cathode layer 4 and the amount of static electricity absorbed by the cathode layer 4. The number of conductive layers 5 can be set according to actual needs, and is not specifically limited here.

[0070] The organic functional layer 3 may include a hole injection layer (HIL), a hole transport layer (HIL), a light emitting layer, an electron transport layer (ETL) and an electron injection layer (EIL) stacked in sequence. The organic functional layer forms a plurality of pixels distributed in an array in the display area, each pixel includes a plurality of sub-pixels, and each sub-pixel can display a single color, such as a red sub-pixel displays red, a green sub-pixel displays green, and a blue sub-pixel displays blue. The brightness of sub-pixels of different colors in a pixel can be adjusted, and when the sub-pixels are combined and superimposed with colors, multiple colors can be displayed, thereby realizing a full-color display of the display panel.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments, the isolation column 2 includes a first sub-isolation column 21 and a second sub-isolation column 22, the first sub-isolation column 21 is located on a side close to the opening area 11, and the second sub-isolation column 22 is located on a side close to the display area 13; wherein, in the thickness direction of the substrate 1, the number of conductive layers 5 overlapping with the orthographic projection of the first sub-isolation column 21 is greater than or equal to the number of conductive layers overlapping with the orthographic projection of the second sub-isolation column 22. Exemplarily, as Figure 2 As shown, a conductive layer 5 (1) and a conductive layer 5 (2) are provided between the first sub-isolation column 21 near the opening area 11 and the substrate 1, while a conductive layer 5 (1) is provided between the second sub-isolation column 22 near the display area 13 and the substrate 1. Figure 3 As shown, the first sub-isolation column 21 and the second sub-isolation column 22 near the opening area 11 and the substrate 1 are both provided with two conductive layers 5, namely, a conductive layer 5 (1) and a conductive layer 5 (2).

[0072] When a conductive layer 5 is provided between multiple sub-isolation columns 2 and the substrate 1, the number of capacitors in the plane direction of the substrate 1 can be increased, and each capacitor absorbs electrostatic charge on average to avoid electrostatic damage caused by excessive charge accumulation. The sub-isolation columns near the opening area 11 are prone to transmit more static electricity, and by providing a conductive layer 5 with a large number of layers under the sub-isolation columns near the opening area 11, the longitudinal capacitance at the opening area 11 can be increased, absorbing more static electricity, slowing down the speed of static electricity transmission near the opening area 11, and increasing the difficulty of static electricity conduction near the opening area 11.

[0073] In other embodiments, in order to increase the anti-static ability of the opening area 11, an organic thin film layer (ORG) can be further set between the first sub-isolation column 21 near the opening area 11 and the cathode layer 4. The organic thin film layer can increase the difficulty of electrostatic conduction, thereby reducing the amount of charge conducted to the cathode layer 4.

[0074] like Figure 4 As shown, in some embodiments, the display panel 100 further includes at least one connecting line 6, the conductive layer 5 is electrically connected to the fixed potential line through the connecting line 6, and the connecting line 6 is electrically connected to at least the conductive layer 5 (1) near the opening area 11. Figure 2 and Figure 4 As shown, the isolation area 12 of the display panel 100 is provided with a conductive layer 5(1) near the opening area 11, and the conductive layer 5(1) is electrically connected to the connecting line 6, and the connecting line 6 is electrically connected to the light shielding layer 7 connected to the fixed potential line, so the conductive layer 5(1) is electrically connected to the fixed potential line through the connecting line 6. Through the connecting line 6, the conductive layer 5(1) near the opening area 11 is electrically connected to the fixed potential line, that is, the conductive layer 5(1) transmitted to the opening area 11 can conduct static electricity out of the display panel 100 through the fixed potential line, and release static electricity in time. Figure 4 As shown, it includes multiple connecting wires 6, one end of each connecting wire 6 is electrically connected to the conductive layer 5 (1), and the other end is electrically connected to the shading layer 7. Therefore, the conductive layer 5 (1) can be electrically connected to the shading layer 7 through the connecting wire 6, and then the static electricity is conducted to the fixed potential line through the shading layer 7, and then the static electricity is conducted out of the display panel 100 through the fixed potential line.

[0075] like Figure 5 As shown, in some embodiments, the display panel 100 further includes a merged line 8, and the connecting line 6 includes a plurality of lines, one end of the connecting line 6 is electrically connected to the conductive layer 5 near the opening area 11, and the other ends of the plurality of connecting lines 6 are electrically connected to the merged line 8. The merged line 8 is electrically connected to the fixed potential line, so that the conductive layer 5 near the opening area 11 is electrically connected to the fixed potential line through the connecting line 6 and the merged line 8, so that the static electricity of the conductive layer 5 is timely conducted out of the display panel 100. The setting of the merged line 8 can reduce the difficulty of wiring the connecting line 6 and reduce the difficulty of manufacturing the display panel 100. For example, Figure 5As shown, the merging line 8 is located between the display area 13 and the spacer 2 .

[0076] like Figure 5 As shown, in some embodiments, the display area 13 includes a scan line 9, the scan line 9 is arranged along the first direction and extends along the second direction, a portion of the scan line 9 extends along the second direction around the edge of the opening area 11, and the scan line 9 does not overlap with the merge line 8. Here, the first direction is the up-down direction viewed along the paper surface, and the second direction is the left-right direction viewed along the paper surface.

[0077] In other embodiments, the display area 13 includes a scan line 9 arranged along a first direction, the scan line 9 is arranged along the first direction and extends along a second direction, part of the scan line 9 extends along the second direction around the edge of the opening area 11, and the scan line 9 and the merging line 8 are at least partially overlapped. The overlapping setting of the scan line 9 and the merging line 8 can be set according to actual needs and is not specifically limited here.

[0078] like Figure 6 As shown, in some embodiments, the conductive layer 5 includes a first conductive layer and a second conductive layer, and the first conductive layer and the second conductive layer are both located between at least a portion of the substrate 1 and the isolation column 2; or, the first conductive layer is located between at least a portion of the substrate 1 and the isolation column 2, and the second conductive layer is located on a side of at least a portion of the isolation column 2 away from the substrate 1. For example, Figure 6 As shown, the conductive layer 5 includes a conductive layer 5 (1), a conductive layer 5 (2) and a conductive layer 5 (3), and the isolation column 2 includes a first sub-isolation column 21 and a second sub-isolation column 22, wherein the conductive layer 5 (1) and the conductive layer 5 (2) are disposed between the first sub-isolation column 21 and the second sub-isolation column 22 and the substrate 1, and a conductive layer 5 (3) is further disposed on the side of the first sub-isolation column 21 away from the substrate 1. Increasing the number of layers of the conductive layer 5 can improve the antistatic capability of the display panel 100, and provide the display panel 100 with a variety of paths for discharging static electricity, so that when static electricity appears on the display panel 100, the static electricity can be discharged in time, thereby improving the antistatic capability of the display panel 100.

[0079] like Figure 7 As shown, in some embodiments, at least part of the first conductive layer and the second conductive layer are electrically connected through vias. Figure 7 As shown, the conductive layer 5(1) near the opening area 11 and the conductive layer 5(2) near the opening area 11 are connected through a via. The conductive layer 5(1) and the conductive layer 5(2) connected through the via are electrically connected to the fixed potential line, so that the static electricity transmitted to the conductive layer 5(1) and the conductive layer 5(2) can be promptly conducted out of the display panel 100, thereby avoiding static electricity damage caused by excessive accumulation of charges.

[0080] like Figure 7As shown, in some embodiments, at least part of the conductive layer 5 is insulated from the isolation column 2. Figure 7 As shown, the conductive layer 5 ( 1 ) and the conductive layer 5 ( 2 ) are both insulated from the isolation column 2 .

[0081] like Figure 8 As shown, in some embodiments, at least part of the conductive layer 5 is electrically connected to the isolation column 2 through a via. Figure 8 As shown, the first sub-isolation column 21 near the opening area 11 is electrically connected to the conductive layer 5 (1) and the conductive layer 5 (2) through a via. The conductive layer 5 is connected to the isolation column 2 through a via, which can quickly conduct static electricity transferred to the isolation column 2 out of the display panel 100, improve the anti-static ability of the display panel 100, and improve the yield rate of the display panel 100 passing the ESD test.

[0082] like Figure 4 As shown, in some embodiments, the display panel further includes a light shielding layer 7, which is located in the display area 13, and the conductive layer 5 is located between the isolation column 2 and the substrate 1. The light shielding layer 7 and the conductive layer 5 are arranged in the same layer, and the conductive layer 5 and the isolation column 2 are connected or insulated through vias. The light shielding layer 7 is used to shield the active layer in the pixel driving circuit to prevent light from irradiating the active layer and affecting the electrical characteristics of the transistor. When the light shielding layer 7 is a metal material, the material of the light shielding layer 7 can be, for example, aluminum, molybdenum, aluminum-neodymium alloy, or molybdenum-neodymium alloy. Figure 3 and Figure 4 It can be seen that when the light shielding layer 7 is provided at the same layer as the conductive layer 5 ( 1 ), the process flow of preparing the conductive layer 5 ( 1 ) can be simplified, thereby reducing the difficulty of preparing the display panel 100 .

[0083] Please continue reading Figure 4 The light shielding layer 7 is provided with a shielding portion 71 in a grid structure in the display area 13, and the conductive layer 5 is electrically connected to the shielding portion 71; the light shielding layer 7 is electrically connected to a fixed potential line (not shown in the figure), and the fixed potential line includes any one of a ground line and a first power supply voltage line. Here, the first power supply voltage line is a PVDD voltage line. When the conductive layer 5 is electrically connected to the shielding portion 71, static electricity is transmitted to the light shielding layer 7 through the conductive layer 5, and static electricity can be promptly discharged from the display panel 100 through the ground line or the PVDD voltage line to release static electricity.

The driving circuit layer is used to drive the corresponding sub-pixels in the display area to emit light. When the conductive layer 5 is arranged between the isolation column 2 and the substrate 1, the conductive layer 5 can be arranged in the same layer as any metal layer in the pixel driving circuit layer. Here, the first metal layer and the second metal layer are the gate metal layer and the source and drain metal layer formed in the transistor, and the fourth metal layer can be a power signal line, a data signal line, a reset signal line, a scan signal line, an initialization signal line, etc. The material of each metal layer in the driving circuit layer can be aluminum, titanium, molybdenum, copper, nickel or other alloys. The conductive layer 5 is arranged in the same layer as any metal layer in the driving circuit layer, which can save the process steps of the conductive layer 5.

[0085] In some embodiments, the display panel 100 further includes a touch layer, the touch layer includes a first touch layer and a second touch layer, the first touch layer is located between the second touch layer and the organic functional layer 3, and the conductive layer 5 is disposed in the same layer as the first touch layer or the second touch layer. Figure 6 As shown, when the conductive layer 5 (3) is arranged on the side of the isolation column 2 away from the substrate 1, the conductive layer 5 (3) can be arranged on the same layer as the first touch layer or the second touch layer, saving the preparation process steps of the conductive layer 5 (3) and reducing the difficulty of preparing the display panel 100.

[0086] like Figure 1 As shown, the display panel 100 further includes a non-display area 14, which at least partially surrounds the display area 13; the non-display area 14 includes a static electricity lead-out line 10, which is arranged around the display area 13, and at least one conductive layer 5 is electrically connected to the static electricity lead-out line 10. For example, Figure 5 and Figure 6 As shown, the display panel includes a conductive layer 5 (3), which is located on the side of the isolation column 2 away from the substrate 1. The conductive layer 5 (3) is electrically connected to the static electricity extraction line 10 through the merging line 8, so that the static electricity transmitted to the conductive layer 5 (3) can be discharged out of the display panel 100 through the static electricity extraction line 10. For example, Figure 2 In the display panel 100 shown, the conductive layer 5 ( 1 ) can be electrically connected to the static electricity extraction line 10 , so that the static electricity transferred to the conductive layer 5 ( 1 ) can be extracted outside the display panel 100 through the static electricity extraction line 10 .

[0087] Accordingly, the present application also provides a display device, which includes the above display panel. Fig. 9As shown, an embodiment of the present invention further provides a display device 200, including the display panel 100 as described above.
