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 those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0034] In the prior art, sealants are often used for packaging. Due to the curing defects, porosity, and weak bonding with the substrate and cover of the sealant, water and oxygen can easily penetrate through the gap into the internal sealing area, thereby shortening the life of the OLED device. How to provide a display panel to solve the problem of water and oxygen invading the interior of the OLED is one of the technical problems that technicians in this field need to solve urgently. Therefore, this application proposes the following solution based on the above technical problem.

[0035] See also Figures 1 to 4 The present application provides a display panel 10, comprising a substrate 200, a light-emitting functional layer 500 arranged on one side of the substrate 200; a cover plate 100 arranged on the light-emitting functional layer 500, the cover plate 100 comprising a first portion 101 and a second portion 102 arranged continuously, the second portion 102 being arranged at the periphery of the light-emitting functional layer 500, and the second portion 102 being arranged between the substrate 200 and the first portion 101; a sealing member 300 arranged between the substrate 200 and the second portion 102, the substrate 200 being connected to the second portion 102 via the sealing member 300.

[0036] In this embodiment, the display panel 10 includes an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0037] In this example, see Figure 3 The light-emitting functional layer 500 includes an anode 501 , a hole injection layer 502 , a hole transport layer 503 , a light-emitting layer 504 , an electron transport layer 505 , an electron injection layer 506 , and a cathode 507 .

[0038] In this example, see Figure 4, a thin film transistor array layer 207 is disposed on the substrate 200, and the thin film transistor array layer 207 may include a plurality of thin film transistors 201, and the thin film transistors 201 may be of an etching barrier type, a back channel etching type, or may be divided into a bottom gate thin film transistor, a top gate thin film transistor, and other structures according to the position of the gate and the active layer, and there is no specific limitation. For example, Figure 4 The thin film transistor 201 shown in the figure is a top-gate thin film transistor, which may include a light-shielding layer 202 arranged on the substrate 200, a buffer layer 210 arranged on the light-shielding layer 202, an active layer 203 arranged on the buffer layer 210, a gate insulating layer 204 arranged on the active layer 203, a gate layer 205 arranged on the gate insulating layer 204, an inter-insulating layer 220 arranged on the gate layer 205, a source-drain layer 206 arranged on the inter-insulating layer 220, and a planarizing layer 230 arranged on the source-drain layer 206.

[0039] In this embodiment, the display panel 10 may further include a transition layer (not shown in the figure) disposed on the light-emitting functional layer 500 , and a touch layer (not shown in the figure) may be disposed on the transition layer.

[0040] In this embodiment, the materials of the substrate 200, the cover plate 100, and the sealing member 300 are materials with high transparency, non-water absorption and stable performance, including ABS (Acrylonitrile-Butadiene-Styrene), PMMA (polymethyl methacrylate), PI (polyimide), etc.

[0041] In the present application, the first part 101 and the second part 102 are continuously arranged on the cover plate 100, and the second part 102 is directly in contact with the sealing member 300, thereby reducing the thickness of the sealing member 300 in the vertical direction, thereby reducing the possibility of cracks in the sealing member 300; at the same time, the sealing member 300 is thinner in the vertical direction and is less likely to flow during the manufacturing process, which is conducive to better docking and sealing between the cover plate 100 and the sealing member 300; therefore, the technical problem of water and oxygen invading the interior of the OLED can be solved.

[0042] The technical solution of the present application is now described in conjunction with specific embodiments. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0043] In the display panel 10 of the present application, the first portion 101 and the second portion 102 are vertically arranged.

[0044] In this embodiment, the cover plate includes a first portion 101 and a second portion 102 which are continuously arranged. The first portion 101 is perpendicular to the second portion 102 . The first portion 101 and the second portion 102 form a cavity with an accommodating space.

[0045] In this embodiment, the first part 101 and the second part 102 are integrally formed, and the manufacturing process thereof may include an injection molding process, an extrusion process, a blow molding process, etc.

[0046] In this embodiment, the included angle between the first portion 101 and the second portion 102 may be an obtuse angle, that is, the included angle between the first portion and the second portion is greater than 90 degrees and less than 180 degrees.

[0047] By vertically arranging the first part 101 and the second part 102 , during the packaging of the OLED, the vertical downward force applied to the cover plate 100 can be fully transmitted along the axial direction of the second part 102 , so that the second part 102 is in closer contact with the sealing member 300 .

[0048] In this embodiment, the first part 101 and the second part 102 are vertically arranged. During the combination of the cover plate 100, the applied force can be fully acted on the contact surface between the second part 102 and the sealing member 300, so that the contact between the two is closer.

[0049] In the display panel 10 of the present application, the sealing member 300 contacts the end surface of the second portion 102 facing the substrate, the projection of the second portion 102 is located within the projection area of ​​the sealing member, and the horizontal size of the sealing member 300 is greater than the horizontal size of the second portion 102.

[0050] In this embodiment, the size of the sealing member 300 in the horizontal direction is greater than the size of the second portion 102 in the horizontal direction, that is, the thickness of the sealing member 300 in the horizontal direction is greater than the thickness of the second portion 102 in the horizontal direction.

[0051] Due to the curing defects, porosity, and weak bonding force between the sealant and the substrate 200 and the cover plate 100, water and oxygen can easily penetrate through the gap into the internal sealing area, thereby shortening the life of the OLED device. In order to achieve a better sealing effect, the sealing member 300 needs to be in full contact with the end surface of the second part 102 facing the substrate 200, that is, the size of the sealing member 300 in the horizontal direction is larger than the size of the second part 102 in the horizontal direction, thereby increasing the contact area between the second part 102 and the sealing member 300.

[0052] In this embodiment, by setting the horizontal dimension of the sealing member 300 to be larger than the horizontal dimension of the second portion 102 , the contact area between the end of the second portion 102 and the sealing member 300 is larger, thereby achieving a better sealing effect.

[0053] In the display panel 10 of the present application, the sealing member 300 includes a sealing body 302 and a first protrusion 301 which are continuously arranged. The first protrusion 301 is located on a side of the sealing body 302 facing the light-emitting functional layer 500 . The sealing body 302 contacts the second portion 102 .

[0054] Since the sealing member 300 contacts the second portion 102 in a molten state, the sealing member 300 overflows to both sides, thereby forming the sealing body 302 and the first protruding portion 301 and the second protruding portion 303 located inside the sealing body.

[0055] In this example, see Figure 2A The sealing member 300 includes a sealing body 302 and a first protruding portion 301 located inside the sealing body 302 .

[0056] In this example, see Figure 2B The sealing member 300 includes a sealing body 302 , a first protruding portion 301 located inside the sealing body 302 , and a second protruding portion 303 located outside the sealing body 302 .

[0057] In this embodiment, the sealing member 300 includes a sealing body 302, a first protruding portion 301 located inside the sealing body 302, and a second protruding portion 303 located outside the sealing body, wherein the second protruding portion 303 can be removed by a process.

[0058] The first protrusion 301 and the second protrusion 303 can further increase the thickness of the sealing member 300 in the horizontal direction, thereby reducing the risk of water and oxygen intrusion.

[0059] In this embodiment, by disposing a first protruding portion 301 on the inner side of the sealing body 302 and a second protruding portion 303 on the outer side of the sealing body 302 , the thickness of the sealing member 300 in the horizontal direction can be increased, thereby reducing the risk of water and oxygen intrusion.

[0060] In the display panel 10 of the present application, the display panel 10 also includes an air-gettering glue 400 arranged on the periphery of the light-emitting functional layer 500, and the air-gettering glue 400 is arranged between the light-emitting functional layer 500 and the second part 102, wherein the first end of the air-gettering glue 400 contacts the first part 101, and the second end of the air-gettering glue 400 contacts the substrate 200.

[0061] In this embodiment, the getter glue 400 is an elastic colloid that can absorb water, oxygen, etc. in the air.

[0062] In this example, see Figure 2A and Figure 2B , the upper surface of the getter glue 400 is higher than the upper surface of the light-emitting functional layer 500 .

[0063] In this embodiment, if the upper surface of the light-emitting functional layer 500 includes a transition layer, the upper surface of the getter glue 400 may be flush with the upper surface of the transition layer.

[0064] When cracks appear in the sealing member 300 and water and oxygen penetrate into the display panel 10 along the cracks, the getter glue 400 arranged on the inner side of the second part 102 surrounds the light-emitting functional layer 500, and the upper surface of the getter glue 400 contacts the first part 101, which is equivalent to the getter glue 400 constructing a sealed space inside the display panel 10 to further isolate water and oxygen, reduce the possibility of water and oxygen contacting the OLED, and thus reduce the damage to the display panel 10.

[0065] Through the above arrangement, the getter glue 400 of this embodiment can construct a sealed space inside the display panel 10 to further isolate water and oxygen, thereby reducing the damage caused by water and oxygen to the display panel 10.

[0066] In the display panel 10 of the present application, the sealing member 300 and the getter glue 400 are disposed separately.

[0067] In this example, see Figure 5 The sealing member 300 is arranged around the periphery of the getter glue 400, and the sealing member 300 maintains a certain distance from the getter glue 400.

[0068] In this embodiment, the size of the sealing member 300 in the horizontal direction is greater than the size of the second portion 102 in the horizontal direction.

[0069] In this embodiment, the vertical dimension of the sealing member 300 is smaller than the vertical dimension of the second portion 102 .

[0070] By setting a gap between the sealing member 300 and the getter glue 400, on the one hand, it can provide a space for water and oxygen to invade, so that the getter glue 400 can absorb water and oxygen. On the other hand, by setting a gap between the sealing member 300 and the getter glue 400, during the sealing process of the sealing member 300 and the cover plate 100, a space is provided for the sealing member 300 to overflow to both sides due to being squeezed, so as to prevent the overflowing sealing member 300 from affecting the getter glue 400.

[0071] In this embodiment, the sealing member 300 is separately arranged from the getter glue 400, so as to provide a containing space for water and oxygen invasion, and prevent the overflowing sealing member 300 from affecting the getter glue 400.

[0072] In the display panel 10 of the present application, the light-emitting functional layer 500 includes a cathode 507 away from the substrate 200 , and the cathode 507 is disposed separately from the first portion 101 .

[0073] In this embodiment, the light-emitting functional layer 500 includes an anode 501, a hole injection layer 502, a hole transport layer 503, a light-emitting layer 504, an electron transport layer 505, an electron injection layer 506, and a cathode 507, and the upper surface of the cathode 507 is separated from the first part 101.

[0074] In this embodiment, a transition layer may be disposed on the upper surface of the cathode 507 to protect the cathode 507 .

[0075] By providing a gap between the upper surface of the cathode 507 and the first portion 101 , it is possible to prevent the lower surface of the first portion 101 of the cover plate 100 from damaging the upper surface of the cathode 507 during the process of pressing the cover plate 100 down for sealing.

[0076] In the display panel 10 of the present application, the end surface of the second portion 102 that contacts the sealing member 300 is a non-planar surface.

[0077] In this example, see Fig. 6A The end surface of the second portion 102 that contacts the sealing member 300 is a plane.

[0078] In this example, see FIG. 6B to FIG. 6F The end surface of the second portion 102 in contact with the sealing member 300 is a non-planar surface, including an inclined surface and a surface with a pattern. Figure 6B, the end surface of the second part 102 in contact with the sealing member 300 is an inclined surface. When the end surface of the second part 102 is set as a pattern, the pattern includes regular patterns and irregular patterns. Preferably, the cross-sectional shape of the end surface includes a sawtooth shape, a step shape, and a wave shape. Figure 6C The end surface of the second portion 102 in contact with the sealing member 300 is serrated. Fig.6D The end surface of the second portion 102 in contact with the sealing member 300 is stepped. Fig. 6E The end surface of the second portion 102 in contact with the sealing member 300 is in the first wave shape. Fig. 6F The end surface of the second portion 102 that contacts the sealing member 300 is a second wave shape.

[0079] In this embodiment, the end surface of the second portion 102 in contact with the sealing member 300 is set to be a non-planar surface, so that the contact area between the second portion 102 and the sealing member 300 can be further increased to achieve a better sealing effect.

[0080] In the display panel 10 of the present application, the sealing member 300 , the substrate 200 , and the cover plate 100 are made of the same material.

[0081] In this embodiment, the sealing member 300 , the substrate 200 and the cover plate 100 are made of the same material.

[0082] In this embodiment, at least two of the sealing member 300 , the substrate 200 and the cover plate 100 are made of the same material.

[0083] In this embodiment, the sealing member 300 , the substrate 200 and the cover plate 100 may be made of three different materials.

[0084] In this embodiment, the material of the cover plate 100 is a material with high transparency, non-water absorption and stable performance, including ABS (Acrylonitrile-Butadiene-Styrene), PMMA (polymethyl methacrylate), PI (polyimide), etc.

[0085] By setting the sealing member 300, the substrate 200 and the cover plate 100 to be made of the same material, the bonding force between the same materials can be used to improve the packaging effect. At the same time, by taking advantage of the advantages of easy processing, good impact resistance and not easy to break, this type of material can be applied to a variety of scenarios, such as the display screen of the slapping game. Furthermore, using the same material as the sealing member can reduce the production cost of the display panel 10.

[0086] In this embodiment, the sealing member 300 , the substrate 200 and the cover plate 100 are made of the same material, and the bonding force between the same materials is stronger, so as to improve the packaging effect and the impact resistance, thereby reducing the production cost of the display panel 10 .

[0087] The present application also provides a mobile terminal, wherein the mobile terminal includes a terminal body and the above-mentioned display panel 10, and the display panel 10 and the terminal body are combined into one body.

[0088] See also 7A to 7E and Figure 8 , the present application also provides a method for manufacturing a display panel 10:

[0089] S100 , providing a substrate 200 .

[0090] In this example, see Fig. 7A The material of the substrate 200 is a material with high transparency, no water absorption and stable performance, including ABS (Acrylonitrile-Butadiene-Styrene), PMMA (polymethyl methacrylate), PI (polyimide), etc. Preferably, the substrate, the cover plate and the sealing member are made of the same material.

For example, Figure 4 The thin film transistor 201 shown in the figure is a top-gate thin film transistor, which may include a light-shielding layer 202 arranged on the substrate 200, a buffer layer 210 arranged on the light-shielding layer 202, an active layer 203 arranged on the buffer layer 210, a gate insulating layer 204 arranged on the active layer 203, a gate layer 205 arranged on the gate insulating layer 204, an inter-insulating layer 220 arranged on the gate layer 205, a source-drain layer 206 arranged on the inter-insulating layer 220, and a planarizing layer 230 arranged on the source-drain layer 206.

[0093] In this example, see Figure 3The light-emitting functional layer 500 includes an anode 501, a hole injection layer 502, a hole transport layer 503, a light-emitting layer 504, an electron transport layer 505, an electron injection layer 506, and a cathode 507 which are manufactured in sequence.

[0094] In this embodiment, the anode 501 is manufactured by electroplating.

[0095] In this embodiment, the hole injection layer 502, the hole transport layer 503, and the light emitting layer 504 are manufactured by inkjet printing or vacuum evaporation process.

[0096] In this embodiment, the electron transport layer 505, the electron injection layer 506, and the cathode 507 are manufactured by vacuum evaporation process.

[0097] In this embodiment, a transition layer may be formed on the upper surface of the cathode 507 to protect the cathode.

[0098] S300 , coating a getter glue 400 on the periphery of the light-emitting functional layer 500 on the substrate 200 .

[0099] In this example, see Figure 5 The getter glue 400 is coated around the outer periphery of the light-emitting functional layer 500.

[0100] In this example, see Figure 7C , the upper surface of the getter glue 400 is higher than the upper surface of the light-emitting functional layer 500 .

[0101] In this embodiment, if the upper surface of the light-emitting functional layer 500 includes a transition layer, the upper surface of the getter glue 400 may be flush with the upper surface of the transition layer.

After the molten ABS is cooled and solidified, it can be integrated with the second part 102 to obtain a complete packaging structure. The molten ABS and the second part 102 are made of the same material. Based on the principle that the bonding force between the same materials is stronger, the molten ABS and the second part 102 will become a whole after cooling.
