Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods and means well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0064] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0065] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0066] The present application provides a display panel according to a first aspect. Figure 1 The schematic diagram of the top view of the display panel shown in FIG. Figure 2 The cross-sectional structure diagram of the display panel shown in the figure includes a display area 10 , a hole area 20 and a partition area 30 . The display area 10 at least partially surrounds the hole area 20 , and the partition area 30 is located between the hole area 20 and the display area 10 .

[0067] In one embodiment, the display panel includes: a substrate 100; a plurality of first isolation structures 200; a plurality of light-emitting devices 300; and an insulating structure 400; the plurality of first isolation structures 200 are located in the partition area 30 and on one side of the substrate 100, and the plurality of first isolation structures 200 include a first sub-isolation structure 210; the light-emitting device 300 includes a light-emitting functional layer 310 and a first electrode layer 320, the first electrode layer 320 is located on the side of the light-emitting functional layer 310 away from the substrate 100, the first electrode layer 320 is arranged in the display area 10 and the partition area 30, a portion of the first electrode layer 320 is located on the side of the first sub-isolation structure 210 away from the substrate 100, and the first sub-isolation structure 210 isolates the first electrode layer 320; the insulating structure 400 is located between at least two adjacent first sub-isolation structures 210.

[0068] It is understandable that after the first sub-isolation structure 210 separates the first electrode layer 320 , part of the first electrode layer 320 is located on the surface of the first sub-isolation structure 210 away from the substrate 100 , and part of the first electrode layer 320 is located between adjacent first sub-isolation structures 210 .

[0069] Exemplarily, the substrate 100 is generally an array substrate having a pixel driving circuit therein.

[0070] In the prior art, the hole area 20 of the display panel is generally the area where the camera is located. During the use of the display panel, ESD (Electro-Static Discharge) charges are easily stimulated due to friction and other operations, which stimulates an electric field in the hole area 20. The electric field induces negative ions to invade the display area 10 of the display panel, causing the pixel driving circuit characteristics at the edge of the hole area 20 to shift and eventually light up.

[0071] According to the display panel provided in the embodiment of the present application, an insulating structure 400 is arranged between adjacent first sub-isolation structures 210, which is beneficial to blocking the ion or electron conduction between the first electrode layers 320 on the surfaces of adjacent first sub-isolation structures 210, avoiding the residual charge in the hole area 20 from being conducted to the display area 10, and can also avoid charge accumulation in the partition area 30, thereby helping to avoid the brightening phenomenon at the edge of the hole area 20 caused by the circuit characteristic deviation in the substrate 100 at the edge of the hole area 20, thereby improving the yield of the display panel.

[0072] Optionally, the surface of the first electrode layer 320 in the partition area 30 facing away from the substrate 100 has an insulating layer. For example, oxygen can be used to oxidize the surface of the first electrode layer 320 facing away from the substrate 100 to form an insulating layer, which has a better insulating effect.

[0073] In one embodiment, referring to Figure 3The cross-sectional structure diagram of the display panel shown in the figure, the display panel further includes: a pixel defining layer 500, located between the first isolation structure 200 and the substrate 100; optionally, the surface of the pixel defining layer 500 facing away from the substrate 100 has a fifth groove 550, and the fifth groove 550 is located between adjacent first sub-isolation structures 210. Therefore, after the first sub-isolation structure 210 isolates the first electrode layer 320, part of the first electrode layer 320 is located on the surface of the first sub-isolation structure 210 facing away from the substrate 100, and part of the first electrode layer 320 is located in the fifth groove 550, which is conducive to avoiding contact between the first electrode layer 320 and the isolation structure 200.

[0074] In one embodiment, referring to Figure 4 The cross-sectional structure diagram of the display panel shown in the figure, the display panel further includes: a second isolation structure 600, located in the display area 10, and located on the same side of the substrate 100 as the first isolation structure 200, the second isolation structure 600 surrounds a plurality of isolation openings 610, and at least part of the light emitting devices 300 are located in the isolation openings 610; optionally, the first isolation structure 200 and the second isolation structure 600 are arranged in the same layer. For example, the first isolation structure 200 and the second isolation structure 600 are prepared by the same preparation process.

[0075] Optionally, the pixel defining layer 500 is located between the first isolation structure 200 , the second isolation structure 600 and the substrate 100 .

[0076] It is understandable that the materials forming the first isolation structure 200 and the second isolation structure 600 are the same; for example, the materials forming the first isolation structure 200 and the second isolation structure 600 include conductive materials, such as a stacked titanium, aluminum, and titanium structure. Exemplarily, in the case where the first isolation structure 200 is conductive, the setting of the fifth groove 550 in the present application is conducive to avoiding the first electrode layer 320 located between adjacent first sub-isolation structures 210 from being electrically connected to the first sub-isolation structure 210, thereby preventing the residual charge in the hole area 20 from being transmitted to the display area, and preventing the hole area edge from being illuminated.

[0077] In one embodiment, referring to Figure 2 The insulating structure 400 includes a first portion 410 and a second portion 420 connected to each other. The first portion 410 is located on a side of the first electrode layer 320 facing away from the substrate 100 , and the second portion 420 is located between adjacent first sub-isolation structures 210 .

[0078] Optionally, the orthographic projection of the second portion 420 on the substrate 100 is located within the orthographic projection range of the first portion 410 on the substrate 100. For example, the second portion 420 fills the gap between adjacent first sub-isolation structures 210, and part of the first portion 410 is located on the surface of the first electrode layer 320 away from the substrate 100, which has a better insulation effect and a better effect of preventing charge from being transmitted in the first electrode layer 320 in the isolation area 30.

[0079] In one embodiment, referring to Figure 5 In the schematic diagram of the cross-sectional structure of the display panel shown, the surface of the pixel defining layer 500 facing away from the substrate 100 has a first groove 510, the first groove 510 is located on the side of the first sub-isolation structure 210 close to the display area 10, and the first groove 510 is used to isolate the first electrode layer 320. It can be understood that during the preparation process, the first electrode layer 320 is isolated at the first groove 510, which is conducive to avoiding the transmission of charges in the first electrode layer 320 in the isolation area 30.

[0080] Optionally, the depth of the first groove 510 is less than or equal to the thickness of the pixel defining layer 500 .

[0081] In one embodiment, referring to Figure 6 As shown in the cross-sectional structural diagram of the display panel, the multiple first isolation structures 200 also include a second sub-isolation structure 220, the second sub-isolation structure 220 is located on the side of the first sub-isolation structure 210 away from the display area 10, and part of the first electrode layer 320 is located on the side of the second sub-isolation structure 220 away from the substrate 100.

[0082] It can be understood that the second sub-isolation structure 220 is used to isolate the first electrode layer 320 , part of the first electrode layer 320 is located on the surface of the second sub-isolation structure 220 away from the substrate 100 , and part of the first electrode layer 320 is located between adjacent second sub-isolation structures 220 .

Thus, when the display panel is cut to obtain the hole area 20, the second groove 520 is conducive to blocking the cutting crack from extending to the display area 10, for example, the second groove 520 is conducive to blocking the cutting crack from extending to the display area 10 through the inorganic layer (for example, the pixel definition layer 500).

[0084] Optionally, the depth of the second groove 520 is less than or equal to the thickness of the pixel defining layer 500 . Preferably, the depth of the second groove 520 is equal to the thickness of the pixel defining layer 500 .

[0085] It can be understood that when the depth of the second groove 520 is equal to the thickness of the pixel defining layer 500 , the second groove 520 penetrates the pixel defining layer 500 .

[0086] In one embodiment, a third groove 530 is provided between the first layer second sub-isolation structure and the second layer second sub-isolation structure and on the surface of the pixel defining layer 500 facing away from the substrate 100 , which is more conducive to preventing cutting cracks from extending through the inorganic layer (such as the pixel defining layer 500 ) to the display area 10 .

[0087] Optionally, the depth of the third groove 530 is less than or equal to the thickness of the pixel defining layer 500 . Preferably, the depth of the third groove 530 is equal to the thickness of the pixel defining layer 500 .

[0088] It can be understood that when the depth of the third groove 530 is equal to the thickness of the pixel defining layer 500 , the third groove 530 penetrates the pixel defining layer 500 .

Thus, the dam 700 is conducive to blocking the intrusion of water vapor into the display area 10, and is also conducive to blocking the organic film layer in the encapsulation layer.

[0090] In one embodiment, referring to Figure 7 The display panel further includes: an encapsulation layer 800, and the encapsulation layer 800 is located on the side of the first electrode layer 320 away from the substrate 100. Thus, it is beneficial to reduce the intrusion of water vapor into the display area 10, and it is beneficial to improve the yield of the display panel.

[0091] Optionally, the encapsulation layer 800 includes a first encapsulation layer 810, a second encapsulation layer 820, and a third encapsulation layer 830 that are stacked, and the first encapsulation layer 810 is located on a side of the second encapsulation layer 820 close to the substrate 100. For example, the first encapsulation layer 810 and the third encapsulation layer 830 are inorganic encapsulation layers, and the second encapsulation layer 820 is an organic encapsulation layer.

[0092] Exemplarily, the orthographic projections of the first encapsulation layer 810 and the third encapsulation layer 830 on the substrate 100 cover the orthographic projection of the first isolation structure 200 on the substrate 100 .

[0093] Exemplarily, the first encapsulation layer 810 and the third encapsulation layer 830 extend to the side of the dam 700 away from the display area 100, and the second encapsulation layer 820 is located on the side of the dam 700 close to the display area 100. The first encapsulation layer 810, the second encapsulation layer 820 and the third encapsulation layer 830 cooperate to effectively block water vapor from invading the display area 10.

[0094] Exemplarily, the first electrode layer 320 extends to a side of the bank 700 away from the display area 100 .

[0095] Exemplarily, the insulating structure 400 is located on a side of the first encapsulation layer 810 facing away from the substrate 100 .

Thus, the planarization layer 70 can block the charge transfer between the first electrode layers 310 located on the surface of the second sub-isolation structure 220, further preventing the residual charge in the hole area 20 from invading the display area 10; and is also conducive to the subsequent film formation.

[0113] In the prior art, the BKT layer has residual positive charges that cannot be dissipated. Since the polarizer 80 and the display panel 40 are cut, an abnormal electric field will appear in the hole area 20 during the use of the product, causing negative charges to be injected into the interface between the BPF layer and the display panel 40 during continuous operation, resulting in the phenomenon of brightening of the edge of the hole area.

[0114] In one embodiment, referring to Fig. 9 and Fig.10 The display module further includes a barrier layer 93, which is located on a side of the polarizer 80 close to the hole area 20 in a direction parallel to the plane where the substrate 100 is located. Thus, the barrier layer 93 can block the precipitation of ions in the polarizer 80 and prevent negative charges from being injected into the display panel 40.

[0115] In one embodiment, in a direction parallel to the plane where the substrate 100 is located, the barrier layer 93 is located on a side of the display panel 40, the support layer 91 and the back plate 92 close to the hole area 20. Thus, the barrier layer 93 can block the precipitation of ions in the polarizer 80 and can also slow down the invasion of ions into the display panel 40.

[0116] In one embodiment, the barrier layer 93 is conductive, so that the barrier layer 93 can change the transmission path of ions and prevent the ions from invading the display panel 40 .

[0117] The display module of the embodiment of the present application can block the ion precipitation path or change the ion conduction path, and effectively improve the display abnormality caused by the ion invasion into the display panel 40.

[0118] Exemplarily, the display module further includes a cover plate 94 located on a side of the polarizer 80 facing away from the display panel 40 .
