That is, it can be ensured that the total weight of the first support layer with a plurality of hollow grooves and the fillers arranged in each hollow groove is less than the weight of the first support layer without the hollow grooves, thereby ensuring that the weight of the display screen and the electronic device integrated with the display screen is relatively light. In addition, by arranging fillers in each hollow groove, it can be ensured that these fillers can support the buffer layer arranged on the side of the first support layer away from the flexible display panel, so that the flatness of the side of the buffer layer away from the support layer is better, thereby ensuring that the appearance of the back of the display screen is better.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0032] Please refer to Figure 1 , Figure 1 The foldable display screen 00 may include a flexible display panel 01 and a support layer 02 .

[0033] The front side of the flexible display panel 01 in the foldable display screen 00 may be a display surface, and the back side of the flexible display panel 01 may be a side opposite to the display surface.

[0034] The support layer 02 in the folding display screen 00 may be connected to the back of the flexible display panel 01. Here, the support layer 02 may support the flexible display panel 01 to ensure that the flexible display panel has good flatness.

[0035] In order to reduce the weight of the folding display screen 00 , currently, a plurality of grooves C are only provided on the side of the support layer 02 away from the flexible display panel 01 . In this way, the weight of the support layer 02 can be reduced, thereby reducing the weight of the folding display screen 00 .

[0036] The foldable display screen 00 may also generally include a buffer layer 03. The buffer layer 03 may be connected to the side of the support layer 02 away from the display panel 01, and the buffer layer 03 may provide shock absorption and buffering for the flexible display panel 01 to ensure that the flexible display panel 01 is less affected by vibration.

[0037] However, the connection between the support layer 02 and the buffer layer 03 usually requires a vacuum pressure holding process, and during the vacuum pressure holding process, the support layer 02 and the buffer layer 03 need to be placed in a vacuum environment. Since a groove C is provided on the side of the support layer 02 away from the flexible display panel 01, the portion of the buffer layer 03 in the vacuum environment opposite to the groove C is easily pressed into the groove C, resulting in a plurality of inwardly concave pits formed on the side of the buffer layer 03 away from the support layer 02.

[0038] In addition, when the foldable display screen 00 is in operation, the heat generated may increase the temperature inside the groove C, thereby increasing the air pressure inside the groove C. Under the effect of the increased air pressure inside the groove C, the portion of the buffer layer 03 opposite to the groove C will bulge outward, thereby forming multiple convex hulls protruding outward on the side of the buffer layer 03 away from the support layer 02.

[0039] Here, no matter whether a plurality of inwardly sunken pits or a plurality of outwardly protruding bumps are formed on the side of the buffer layer 03 away from the supporting layer 02, the flatness of the side of the buffer layer 03 away from the supporting layer 02 will deteriorate, resulting in a poor appearance of the back of the folding display screen 00.

[0040] Please refer to Figure 2 , Figure 2 000 can be a display screen in a display device such as a mobile phone, a tablet computer, a laptop computer or a display. Here, the display screen 000 can be a folding display screen, or a non-folding curved display screen or a flat display screen. This embodiment of the present application does not limit this. The display screen 000 can include a flexible display panel 100, a first supporting layer 200 and a plurality of filling bodies 300.

[0041] The front side of the flexible display panel 100 in the display screen 000 is a display surface. The flexible display panel 100 can display images through the display surface.

[0042] The first supporting layer 200 in the display screen 000 is connected to the back side of the flexible display panel 100. Here, the back side of the flexible display panel 100 refers to the side opposite to the display surface of the flexible display panel 100. The first supporting layer 200 in the display screen 000 has a plurality of hollow grooves A on the side facing away from the flexible display panel 100.

[0043] The multiple filling bodies 300 in the display screen 000 may correspond to the multiple hollow grooves A. Here, at least a portion of each filling body 300 may be fixed in the corresponding hollow groove A. In this way, the filling body 300 may be arranged in each hollow groove A arranged on the side of the first supporting layer 200 away from the flexible display panel 100.

[0044] The density of the multiple filling bodies 300 in the display screen 000 may be smaller than the density of the first supporting layer 200 .

[0045] In the embodiment of the present application, after a plurality of hollow grooves A are provided on a side of the first supporting layer 200 away from the flexible display panel 100 , the weight of the first supporting layer 200 provided on the back side of the flexible display panel 100 can be reduced.

[0046] Optionally, the display screen 000 may further include a buffer layer 500 . The buffer layer 500 may be distributed on a side of the first supporting layer 200 away from the flexible display panel 100 .

[0047] Here, since the plurality of hollow grooves A disposed on the side of the first supporting layer 200 away from the flexible display panel 100 are filled with the filling body 300, even if the buffer layer 500 is disposed on the side of the first supporting layer 200 away from the flexible display panel 100, the portion of the buffer layer 500 opposite to the hollow groove A can be supported by the filling body 300 located in the hollow groove A.

[0048] In this way, during the process of connecting the first supporting layer 200 and the buffer layer 500 by using the vacuum pressure holding process, even if the first supporting layer 200 and the buffer layer 500 are placed in a vacuum environment, the support of the filler 300 located in the hollow groove A can ensure that the portion of the buffer layer 500 opposite to the hollow groove A is not easily pressed into the hollow groove A. In this way, the probability of forming a plurality of inwardly sunken pits on the side of the buffer layer 500 away from the first supporting layer 200 can be effectively reduced.

[0049] Similarly, in the normal operation of the flexible display screen 300, since the hollow groove A provided on the side of the first supporting layer 200 away from the flexible display panel 100 is filled with the filling body 300, it can be ensured that the heat generated during the operation of the flexible display screen 300 causes the probability of increasing the internal air pressure thereof is small, and thus it can be ensured that the portion of the buffer layer 500 opposite to the hollow groove A will not bulge outward. In this way, the probability of forming a plurality of convex hulls bulging outward on the side of the buffer layer 500 away from the first supporting layer 200 can be effectively reduced.

[0050] To this end, by setting the filler 300 in each hollow groove A distributed on the side of the first supporting layer 200 away from the flexible display panel 100, the flatness of the side of the buffer layer 500 away from the first supporting layer 200 can be effectively improved. Since the density of the filler 300 set in each hollow groove A can be less than the density of the first supporting layer 200, even after the filler 300 is set in each hollow groove A, it can be ensured that the weight of the first supporting layer 200 will not be increased too much. That is, it can be ensured that the total weight of the first supporting layer 200 with multiple hollow grooves A and the filler 300 set in each hollow groove A is less than the weight of the first supporting layer 200 without the hollow groove A.

[0051] In this case, by providing a plurality of hollow grooves A on the side of the first supporting layer 200 away from the flexible display panel 100, and providing a filler 300 with a relatively low density in each hollow groove A, not only can the overall weight of the display screen 000 be ensured to be low, but also the weight of the electronic device integrated with the display screen 000 can be made light. The fillers 300 can also support the portion of the buffer layer 500 opposite to each hollow groove A, so that the side of the buffer layer 500 away from the supporting layer 200 has better flatness, thereby ensuring a better appearance of the back of the display screen 000.

[0052] In summary, the display screen provided by the embodiment of the present application includes: a flexible display panel, a first support layer and a plurality of fillers. Since the density of the fillers arranged in the plurality of hollow grooves on the side of the first support layer in the display screen away from the flexible display panel can be less than the density of the first support layer, even after the fillers are arranged in each hollow groove, it can be ensured that the weight of the first support layer will not be increased too much. That is, it can be ensured that the total weight of the first support layer with a plurality of hollow grooves and the fillers arranged in each hollow groove is less than the weight of the first support layer without the hollow grooves, thereby ensuring that the weight of the display screen and the electronic device integrated with the display screen is light. In addition, by arranging fillers in each hollow groove, it can be ensured that these fillers can support the buffer layer arranged on the side of the first support layer away from the flexible display panel, so that the flatness of the buffer layer on the side away from the support layer is better, thereby ensuring that the appearance of the back of the display screen is better.

[0053] Optional, please refer to Figure 3 , Figure 3 It is a top view of the side of the first supporting layer in a display screen provided in an embodiment of the present application that is away from the flexible display panel. The multiple hollow grooves A set on the side of the first supporting layer 200 in the display screen 000 that is away from the flexible display panel 100 can be arranged in an array, that is, these hollow grooves A can be arranged in multiple columns in the first direction X and in multiple rows in the second direction Y.

[0054] Here, in the first direction X, the distance between any two adjacent hollow grooves A is equal; in the second direction Y, the distance between any two adjacent hollow grooves A is equal; and the distance between two adjacent hollow grooves A distributed in the first direction X can be equal to the distance between two adjacent hollow grooves A distributed in the second direction Y.

[0055] In the embodiments of the present application, Figure 4 As shown, Figure 4 000 is a schematic diagram of the structure of another display screen provided in an embodiment of the present application, and the hollow groove A provided on the side of the first supporting layer 200 in the display screen 000 away from the flexible display panel 100 may be a blind groove. That is, in a direction perpendicular to the display surface of the flexible display panel 100 in the display screen 000, the depth h of the hollow groove A is less than the thickness D of the first supporting layer 200 in the display screen 000.

[0056] Exemplarily, in a direction perpendicular to the display surface of the flexible display panel 100, the depth h of the hollow groove A provided on the side of the first supporting layer 200 away from the flexible display panel 100 satisfies: D / 4≤h≤3D / 4. Wherein, D represents the thickness of the first supporting layer 200 in a direction perpendicular to the display surface of the flexible display panel 100.

[0057] In this way, in the direction perpendicular to the display surface of the flexible display panel 100, it can be ensured that the hollow groove A will not penetrate the first supporting layer 200, so that the side of the first supporting layer 200 facing the flexible display panel 100 can provide better support for the flexible display panel 100, thereby ensuring better flatness of the flexible display panel 100.

[0058] In the embodiment of the present application, the filling body 300 in the display screen 000 may have adhesive properties, and the filling body 300 may be bonded to the inner wall of the hollow groove A provided on the side of the first supporting layer 200 away from the flexible display panel 100 .

[0059] For example, each filling body 300 in the display screen 000 can be made of a resin material with adhesive properties. In this way, after the filling body 300 is filled into the hollow groove A provided on the side of the first support layer 200 away from the flexible display panel 100, the filling body 300 can be directly attached to the inner wall of the hollow groove A. It is not necessary to separately provide an additional adhesive layer between the inner wall of the hollow groove A and the filling body 300, so as to ensure that the filling body 300 can be firmly fixed in the hollow groove A.

[0060] In addition, by directly adhering the adhesive filling body 300 to the inner wall of the hollow groove A, it can also ensure that there is no gap between the inner wall of the hollow groove A and the filling body 300, so that the filling body 300 can completely fill the hollow groove A, thereby ensuring that the filling body A has a better supporting effect on the part of the buffer layer 500 opposite to the hollow groove A.

[0061] Optionally, the side of the filling body 300 in the display screen 000 facing away from the flexible display panel 100 may be flush with the side of the first supporting layer 200 facing away from the flexible display panel 100. That is, the side of the filling body 300 facing away from the flexible display panel 100 will not protrude from the side of the first supporting layer 200 facing away from the flexible display panel 100, and the side of the filling body 300 facing away from the flexible display panel 100 will not be recessed inward relative to the side of the first supporting layer 200 facing away from the flexible display panel 100.

[0062] In this way, after the buffer layer 500 is connected to the side of the first supporting layer 200 facing away from the flexible display panel 100, it can be ensured that the portion of the buffer layer 500 that is arranged opposite to the filling body 300 will not bulge outward relative to other portions of the buffer layer 500, nor will it be recessed inward relative to other portions of the buffer layer 500, thereby further improving the flatness of the side of the buffer layer 500 facing away from the flexible display panel 100, and further improving the appearance of the back of the display screen 000.

[0063] Optionally, the shape of the hollow groove A provided on the side of the first supporting layer 200 in the display screen 000 away from the flexible display panel 100 may be a hemispherical groove or a cylindrical groove.

[0064] Here, since the filling body 300 filled into the hollow groove A is made of an adhesive resin material, and the filling body 300 filled into the hollow groove A can be attached to the inner wall of the hollow groove A, the side of the filling body A away from the flexible display panel 100 can be flush with the side of the first supporting layer 200 away from the flexible display panel 100. Therefore, in the case where the shape of the hollow groove A is a hemispherical groove, the filling body 300 in the display screen 000 can be a hemispherical structure made of resin material; in the case where the shape of the hollow groove A is a cylindrical groove, the filling body 300 in the display screen 000 can be a cylindrical structure made of resin material.

[0065] In the examples of this application, please refer to Figure 5 , Figure 5000 may further include: a second supporting layer 400. Here, the second supporting layer 400 may be connected to the side of the first supporting layer 200 away from the flexible display panel 100, and the second supporting layer 400 may cover a plurality of hollow grooves A provided on the side of the first supporting layer 200 away from the flexible display panel 100.

[0066] For example, the side of the hollow groove A away from the flexible display panel 100 may have an opening, and the hollow groove A may be a semi-enclosed structure with an opening on one side. In this way, after the second supporting layer 400 is connected to the side of the first supporting layer 200 away from the flexible display panel 100, the second supporting layer 400 can seal the hollow groove A set on the side of the first supporting layer 200 away from the flexible display panel 100 as a closed accommodating space. In this way, the filling body 300 filled in the hollow groove A can be sealed by the second supporting layer 400, so that even if the heat is generated during the use of the display screen 000, and the heat makes the filling body 300 filled in the hollow groove A melt into a fluid, it can also ensure that the filling body 300 fused into a fluid will not flow to the outside of the hollow groove A, and then it can be ensured that the filling body 300 fused into a fluid will not interfere with the device set on the back plate of the display screen 000.

[0067] In the present application, since the filling body 300 in the display screen 000 is made of a resin material having adhesiveness, the filling body 300 in the display screen 000 can be attached to the side of the second supporting layer 400 facing the first supporting layer 200 .

[0068] In this case, the filling body 300 can be attached not only to the inner wall of the hollow groove A provided on the side of the first supporting layer 200 away from the flexible display panel 100, but also to the side of the second supporting layer 400 facing the first supporting layer 200. In this way, the filling body 300 can fill the closed accommodation space surrounded by the first supporting layer 200 and the second supporting layer 400, so that there is no gap between the first supporting layer 200 and the second supporting layer 400, thereby ensuring that the first supporting layer 200 and the second supporting layer 400 can better support the flexible display panel 100.

[0069] In addition, since the filling body 300 is adhesive, when the filling body 300 is not only bonded to the inner wall of the hollow groove A set on the side of the first supporting layer 200 away from the flexible display panel 100, but also bonded to the side of the second supporting layer 400 facing the first supporting layer 200, it can be ensured that the first supporting layer 200 and the second supporting layer 400 can also be connected through the filling body 300, thereby improving the firmness of the connection between the first supporting layer 200 and the second supporting layer 300.

[0070] In the embodiment of the present application, the first support layer 200 and the second support layer 400 in the display screen 000 are both layered structures made of metal materials. For example, the first support layer 200 and the second support layer 400 can both be layered structures made of metal copper. Here, the first support layer 200 and the second support layer 400 can be connected together by welding or adhesive.

[0071] When the first supporting layer 200 and the second supporting layer 400 are both layered structures made of metal materials, the first supporting layer 200 and the second supporting layer 400 have good electromagnetic shielding properties after being connected, so that the first supporting layer 200 and the second supporting layer 400 can not only support the flexible display panel 100, but also can electromagnetically shield the back of the flexible display panel 100, so that the flexible display panel 100 is not easily disturbed by external electromagnetic waves during the process of displaying the picture, thereby ensuring that the flexible display panel 100 has a better effect when displaying the picture.

[0072] In the embodiment of the present application, in the direction perpendicular to the display surface of the flexible display panel 100, the sum of the thickness of the first supporting layer 200 and the thickness of the second supporting layer 400 in the display screen 000 ranges from 0.12 mm to 0.18 mm. In this way, the sum of the thickness of the first supporting layer 200 and the second supporting layer 400 as a whole can be ensured to be small, so that the total weight of the first supporting layer 200 and the second supporting layer 400 is small, and thus the overall weight of the display screen 000 can be ensured to be small.

[0073] In summary, the display screen provided by the embodiment of the present application includes: a flexible display panel, a first support layer and a plurality of fillers. Since the density of the fillers arranged in the plurality of hollow grooves on the side of the first support layer in the display screen away from the flexible display panel can be less than the density of the first support layer, even after the fillers are arranged in each hollow groove, it can be ensured that the weight of the first support layer will not be increased too much. That is, it can be ensured that the total weight of the first support layer with a plurality of hollow grooves and the fillers arranged in each hollow groove is less than the weight of the first support layer without the hollow grooves, thereby ensuring that the weight of the display screen and the electronic device integrated with the display screen is light. In addition, by arranging fillers in each hollow groove, it can be ensured that these fillers can support the buffer layer arranged on the side of the first support layer away from the flexible display panel, so that the flatness of the buffer layer on the side away from the support layer is better, thereby ensuring that the appearance of the back of the display screen is better.

[0074] The embodiment of the present application also provides an electronic device, which may be a mobile phone, a tablet computer, a laptop computer, an e-book, etc. The electronic device may include: a housing and a display screen 000 connected to the housing, wherein the display screen 000 is any of the above-mentioned display screens 000.

[0075] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0076] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
