Support column structure and manufacturing method thereof, and display device

Abstract

The present application discloses a support column structure, a manufacturing method thereof, and a display device, which belong to the field of display technology. The support column structure may include: a first support column and a second support column located on a carrier body. In the process of forming the first support column by a first mold and forming the second support column by a second mold, the draft direction of the first mold is different from the draft direction of the second mold. In this way, when the carrier body is a rear shell, if the distance between the front of the rear shell and the display panel is large, the display panel is supported by a combination of the first support column and the second support column, which effectively improves the support strength of the second support column for the display panel, and the connection strength between the second support column and the first support column is high. In this way, the support effect of the display panel can be effectively improved by the first support column and the second support column, thereby effectively improving the reliability of the display device.

[0015] Optionally, the third support plate is an arc-shaped support plate;

[0016] Alternatively, the third support plate includes: a planar support plate and arc-shaped support plates located on both sides of the planar support plate.

[0018] Optionally, the first support column further includes: a third support plate, wherein the third support plate, the first support plate, and the second support plate are all connected to the same side of the carrying body, and the third support plate is respectively connected to the first support plate and the second support plate;

[0036] A support column structure includes: a first support column and a second support column positioned on a supporting body. During the process of forming the first support column using a first mold and the second support column using a second mold, the first mold's ejection direction differs from the second mold's ejection direction. Therefore, the orientation of the first groove of the first support column differs from the orientation of the second groove of the second support column. When the supporting body is a back cover, if the distance between the front of the back cover and the display panel is large, the display panel is supported by the combination of the first and second support columns, and the heights of the individual first and second support columns are both relatively small. This eliminates the need to ensure that the second support column's thickness near the first support column is greater, while allowing the thickness of the second support column farther from the first support column to be greater. This effectively increases the support strength of the second support column for the display panel and ensures a high connection strength between the second support column and the first support column. Furthermore, during the process of forming the first support column using the first mold, the ejection direction of the first mold is perpendicular to the height direction of the first support column, thus ensuring a high connection strength between the first support column and the back cover. Thus, the first and second support columns effectively enhance the support of the display panel, thereby effectively improving the reliability of the display device.

[0051] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0052] In related art, please refer to Figure 1 and Figure 2 , Figure 1 This is a partial structural diagram of a back shell provided by related technology. Figure 2 The back cover 00 generally includes a back cover body 01 and support columns 02 .

[0053] The rear shell body 01 can be connected to the display panel, and the support columns 02 are connected to the front of the rear shell body 01, and the support columns 02 can provide support for the display panel. It should be noted that the front of the rear shell body 01 refers to the side of the rear shell body 01 facing the display panel after the rear shell body 01 is connected to the display panel. Generally speaking, the rear shell body 01 is arranged with multiple support columns 02 of the same structure, and these multiple support columns 02 can provide uniform support for the display panel.

[0054] It should be noted that Figure 1 and Figure 2 Two structures of support column 02 are provided. Figure 1 The middle support column 02 is a thin-walled hollow cylindrical support column 02. Figure 2 The middle support column 02 is a thin-walled H-shaped support column 02.

[0055] Typically, the back cover body 01 and the support pillars 02 in the back cover 00 are formed simultaneously through an injection molding process. In the process of forming the back cover 00 through the injection molding process, it is necessary to pour the injection molding material into the mold. After the injection molding material solidifies, the mold is demolded to obtain the back cover 00 with the support pillars 02.

[0056] During the process of performing the drafting process on the mold to form the support column 02, in order to ensure that the support column 02 can be easily removed from the mold, a certain draft angle needs to be set in the mold. For example, please refer to Figure 3 , Figure 3 : is a schematic diagram illustrating a draft angle provided in an embodiment of the present application. The draft angle α is the angle at which the side wall of the mold 03 is inclined relative to the draft direction A. When there is no draft angle in the mold 03, the friction between the side wall of the mold 03 and the support column 02 is large, and the support column 02 is difficult to be removed from the mold 03. When the mold 03 has a draft angle α, the mold 03 is easily separated from the support column 02, making it easy for the support column 02 to be removed from the mold 02. In this case, the thickness of the support column 02 obtained after the mold 03 with the draft angle α is different at various positions, and the thickness of the support column 02 generally decreases gradually along the draft direction A of the mold 03.

[0057] However, as the thickness of the support column 02 gradually decreases along the ejection direction A toward the mold 03, the higher the height of the support column 01 in the rear housing 00, the smaller the thickness of the top of the support column 02 (i.e., the end of the support column 02 away from the rear housing body 01). Therefore, when the distance between the front of the rear housing body 01 and the display panel is large, and a taller support column 02 is required to support the display panel, the top of the support column 02 has a lower support strength for the display panel, resulting in poor support of the support column 02 for the display panel, and thus poor reliability of the display device.

[0058] In the related art, to ensure that support columns 02 effectively support the display panel, it is necessary to increase the contact area between support columns 02 and the display panel, that is, to increase the thickness of the top of support columns 02. As a result, the bottom of support columns 02 (i.e., the end of support columns 02 away from rear housing 01) is thicker, much thicker than the thickness of rear housing 01. During the simultaneous injection molding process of forming support columns 02 and rear housing 01, support columns 02 and rear housing 01 shrink to different degrees when exposed to cold, resulting in a weak connection between support columns 02 and rear housing 01. Support columns 02 are easily broken from rear housing 01, and the reliability of the display device remains poor.

[0059] Therefore, in the related art, in order to ensure the supporting strength of the support column 02 and the connection strength between the support column 02 and the rear shell body 01, the maximum height of the support column 02 can only be 30 millimeters (mm).

[0060] Please refer to Figure 4 , Figure 4 FIG. 2 is a schematic diagram of a support column structure provided by an embodiment of the present application. The support column structure 000 may include: a first support column 200 and a second support column 300 .

[0061] In the embodiments of this application, Figure 5 As shown, Figure 5 yes Figure 4 The support column structure 000 is generally distributed on the carrier 100. The first support column 200 is connected to one side of the carrier 100, and the second support column 300 is connected to the side of the first support column 200 away from the carrier 100.

[0062] For example, after the carrying body 100 is connected to the support column structure 000 , the carrying body 100 can provide a supporting force to the object to be supported through the support column structure 000 .

[0063] It should be noted that the object to be supported may be a display panel or other objects that need to be supported, and this application does not limit this.

[0064] It should also be noted that, when the object to be supported is a display panel, the supporting body 100 may be a rear cover, and the rear cover may be connected to the display panel.

[0065] In this case, the support column structure 000 can be located on the front side of the rear housing. The front side of the rear housing is the side facing the display panel after the rear housing and display panel are connected. This allows the front side of the rear housing to provide support for the first support columns 200, and the first support columns 200 to provide support for the second support columns 300. Thus, after the display panel and rear housing are connected, the second support columns 300 can provide support for the display panel.

[0066] The first support column 200 in the support column structure 000 has a first groove 200a on its side, and the second support column 300 has a second groove 300a on its side away from the first support column 200. Thus, the opening direction of the first groove 200a is different from that of the second groove 300a.

[0067] In the embodiment of the present application, the first support column 200 and the second support column 300 in the support column structure 000 can be formed by a one-time injection molding process. For example, please refer to Figure 6 , Figure 6This is a schematic diagram illustrating the mold-pulling principle of a support column structure provided by an embodiment of the present application. Because the opening orientation of the first groove 200a of the first support column 200 differs from the opening orientation of the second groove 300a of the second support column 300, two molds are required to form the first support column 200 and the second support column 300, respectively, during the injection molding process.

[0068] For example, after the first mold 200b and the second mold 300b are mated, an injection molding material can be poured between the first mold 200b and the second mold 300b. After the injection molding material solidifies, the first mold 200b and the second mold 300b are demolded. The demolding direction X of the first mold 200b intersects the demolding direction Y of the second mold 300b. In this way, after the first mold 200b and the second mold 300b are demolded, a first support column 200 with a first groove 200a and a second support column 300 with a second groove 300a are obtained, and the opening direction of the first groove 200a is different from the opening direction of the second groove 300a.

[0069] In this case, when the distance between the front surface of the rear housing and the display panel is large, the display panel can be supported by the combination of the first support column 200 and the second support column 300, with the heights of both the individual first support column 200 and the individual second support column 300 being relatively small. This ensures that the second support column 300 is thicker at the end away from the first support column 200, providing greater support strength for the display panel and thus providing better support for the display panel. Furthermore, there is no need to ensure that the second support column 300 is thicker at the end closer to the first support column 200 to ensure a strong connection between the second support column 300 and the first support column 200.

[0070] Furthermore, because the direction of the first mold 200b's ejection is perpendicular to the height of the first support column 200 during the process of forming the first support column 200 using the first mold 200b, the thickness of the first support column 200 is uniform along its height. This allows the first support column 200 to effectively support the second support column 300 without increasing the thickness of the first support column 200 near the rear housing, thereby ensuring a high connection strength between the first support column 200 and the rear housing.

[0071] In summary, embodiments of the present application provide a support column structure comprising: a first support column and a second support column positioned on a supporting body. During the process of forming the first support column using a first mold and the second support column using a second mold, the first mold's draft direction differs from the second mold's draft direction. Therefore, the orientation of the first groove of the first support column differs from the orientation of the second groove of the second support column. Thus, when the supporting body is a rear case, if the distance between the front of the rear case and the display panel is large, the display panel is supported by the combination of the first and second support columns, and the heights of the individual first and second support columns are both relatively small. This eliminates the need to ensure that the second support column has a greater thickness near the first support column while also being thicker at the end away from the first support column. This effectively increases the support strength of the second support column for the display panel and ensures a higher connection strength between the second support column and the first support column. Furthermore, during the process of forming the first support column using the first mold, the first mold's draft direction is perpendicular to the height direction of the first support column, thus ensuring a higher connection strength between the first support column and the rear case. In this way, the first supporting column and the second supporting column can effectively improve the supporting effect of the display panel, thereby effectively improving the reliability of the display device.

[0072] It should be noted that the supporting body 100, the first support column 200, and the second support column 300 are also formed simultaneously through a single injection molding process. Therefore, a third mold is also required to form the supporting body 100. For example, the first mold 200b, the second mold 300b, and the third mold are poured with injection molding material. After the injection molding material solidifies, the first mold 200b, the second mold 300b, and the third mold are demolded to obtain the support column structure 000 and the supporting body 100.

[0073] In the examples of this application, please refer to Figure 7 and Figure 8 , Figure 7 This is a structural diagram of a first support column provided in an embodiment of the present application. Figure 8 2 is a schematic diagram of the structure of another first support column provided in an embodiment of the present application. The first support column 200 in the support column structure 000 includes: a first support plate 201, a second support plate 202, and a connecting plate 203. The first support plate 201 and the second support plate 202 are both connected to the same surface of the carrier body 100. The connecting plate 203 is respectively connected to the side of the first support plate 201 and the second support plate 202 away from the carrier body 100, and the connecting plate 203 is also connected to the second support column 300. It should be noted that in order to ensure that the first support column 200 has a high support strength for the second support column 300, it is necessary to ensure that the side of the first support column 200 away from the opening of the first groove 200a is closed.

[0074] In one case, such as Figure 7 As shown, the first support column 300 may further include a third support plate 204, wherein the first support plate 201, the second support plate 202, and the third support plate 204 are all connected to the same surface of the carrier body 100, and the third support plate 204 is respectively connected to the first support plate 201 and the second support plate 202, and the third support plate 204 is further connected to the connecting plate 203. In this case, the connecting plate 203, the first support plate 201, the second support plate 202, and the third support plate 204 may enclose a first groove 200a.

[0075] In another case, such as Figure 8 As shown, one side of the first support plate 201 is connected to one side of the second support plate 202. In this case, the connecting plate 203, the first support plate 201 and the second support plate 202 may enclose a first groove 200a.

[0076] The connecting plate 203 in the first support column 200 has the same thickness at all locations. To ensure the support strength of the first and second support plates 201, 202 on the connecting plate 203 in the first support column 200, the thickness of the connecting plate 203 cannot be too large. For example, the thickness of the connecting plate 203 in the first support column 200 can be equal to the thickness of the first and second support plates 201, 202 to ensure the strength of the connection between the first and second support plates 201, 202 and the connecting plate 203. In this way, during the process of forming the first support column 200 through the injection molding process, the connection between the connecting plate 203 and the first and second support plates 201, 202 will not be deformed due to the excessive thickness of the connecting plate 203. In this way, the support strength of the first and second support plates 201, 202 on the connecting plate 203 in the first support column 200 is effectively guaranteed.

[0077] At the same time, the thickness of the connecting plate 203 cannot be too small. For example, the thickness of the connecting plate 203 can be greater than the thickness of the bottom of the second support column 300 (that is, the end of the second support column 300 close to the first support column 200), which can ensure that the connection strength of the connecting plate 203 and the second support column 300 is high. In this way, in the process of simultaneously forming the first support column 200 and the second support column 300 through the injection molding process, the connection between the connecting plate 203 and the second support column 300 will not collapse due to the larger thickness of the bottom of the second support column 300. In this way, the connection strength of the connecting plate 203 and the second support column 300 is effectively guaranteed to be high.

[0078] Regarding the first support plate 202 and the second support plate 203 in the first support column 300 , there are multiple possible implementations of the structures of the first support plate 201 and the second support plate 202 . This application intends to schematically illustrate the following two optional implementations.

[0079] In a first implementation, the plane of the first support plate 201 intersects the plane of the second support plate 202. This allows the first mold to be removed from the side away from the intersection of the planes of the first support plate 201 and the second support plate 202 during the process of forming the first support column 201 using the first mold. In this case, even if the thickness of the first support plate 201 and the second support plate 202 are uniform at all locations, the first support column 201 can still be easily removed from the first mold.

[0080] It should be noted that, during the process of forming the first support column 200 using the first mold, the larger the angle between the plane of the first support plate 201 and the draft direction of the first mold, the easier it is to draft the first mold. The minimum draft angle of the first mold can be 0.5 degrees.

[0081] In the present application, the thickness of the first support plate 201 can be equal to the thickness of the second support plate 202. In this case, the strength of the connection between the first support plate 201 and the second support plate 202 and the carrier body 100 can be guaranteed to be the same, thereby improving the connection strength between the first support column 200 and the carrier body 100.

[0082] It should be noted that when the plane where the first support plate 201 is located intersects the plane where the second support plate 202 is located, the first support column 200 may or may not include the third support plate 204. To this end, this application provides schematic illustrations using the following two situations.

[0083] In the first case, when the first support column 200 does not include the third support plate, as shown in FIG. Figure 8 As shown, one side of the first support plate 201 needs to be connected to one side of the second support plate 202. In this case, Figure 9 As shown, Figure 9 This is a top view of a support column structure provided in an embodiment of the present application, in which the shape of a side of the connecting plate 203 facing the second support column 200 is triangular.

[0084] For example, the bottom of the second support column 300 can be connected to the triangular connecting plate 203, and the positive projection of the second support column 300 on the connecting plate 203 is located inside the triangular connecting plate 203, ensuring that the connecting plate 203 can provide support force for the second support column 300.

[0085] It should be noted that since the triangular connecting plate 203 has two sides connected to the first support plate 201 and the second support plate 202, the closer the first support plate 201 and the second support plate 202 are to these two sides, the higher the support strength provided by the connecting plate 203. To ensure that the triangular connecting plate 203 can provide better support for the second support column 300, the connection between the bottom of the second support column 300 and the connecting plate 203 can be as close as possible to the two sides of the triangular connecting plate 203 that are connected to the first support plate 201 and the second support plate 202. This effectively avoids the problem of weak support strength at the connection between the bottom of the second support column 300 and the connecting plate 203 due to weak support strength in the center of the triangular connecting plate 203.

[0086] It should also be noted that when one side of the first support plate 201 is connected to one side of the second support plate 202, the thickness at the connection between the first support plate 201 and the second support plate 202 is typically greater, and is greater than the thickness of the first support plate 201 and the second support plate 202. Therefore, to ensure that the thickness of the first support column 200 is the same at all locations, thereby ensuring a relatively uniform strength at the connection between the first support column 200 and the carrier body 100, an arc-shaped chamfered structure 205 can be provided at the connection between the first support plate 201 and the second support plate 202. The arc-shaped chamfered structure 205 ensures that the thickness at the connection between the first support plate 201 and the second support plate 202 is equal to the thickness of the first support plate 201 and the second support plate 202.

[0087] In the second case, when the first support column 200 includes the third support plate 204, as shown in FIG. Figure 7 As shown, both sides of the third support plate 204 are connected to the first support plate 201 and the second support plate 202 respectively. Figure 10 As shown, Figure 10 This is a top view of another support column structure provided in an embodiment of the present application. The distance d1 between the side of the first support plate 201 in the first support column 200 close to the third support plate 204 and the side of the second support plate 202 close to the third support plate 204 is smaller than the distance d2 between the side of the first support plate 201 away from the third support plate 202 and the side of the second support plate 202 away from the third support plate 204.

[0088] For example, the bottom of the second support column 300 can be connected to the connecting plate 203 , and the orthographic projection of the second support column 300 on the connecting plate 203 is located inside the connecting plate 203 , ensuring that the connecting plate 203 can provide support force for the second support column 300 .

[0089] It should be noted that since the connecting plate 203 has three sides connected to the first support plate 201, the second support plate 202, and the third support plate 204, the closer the connection plate is to these three sides, the higher the support strength provided by the first support plate 201, the second support plate 202, and the third support plate 203 for the connecting plate 203. To ensure that the connecting plate 203 can provide better support for the second support column 300, the connection between the bottom of the second support column 300 and the connecting plate 203 can be as close as possible to the three sides of the connecting plate 203 connected to the first support plate 201, the second support plate 202, and the third support plate 204. This effectively avoids the problem of weak support strength in the central area of ​​the connecting plate 203, which in turn leads to weak connection strength between the bottom of the second support column 300 and the connecting plate 203.

[0090] In the embodiment of the present application, there are various structures of the third support plate 204. The embodiment of the present application is schematically described using the following two cases:

[0091] In the first case, please refer to Figure 11 , Figure 11 FIG. 2 is a top view of another support column structure provided in an embodiment of the present application. The third support plate 204 may be an arc-shaped support plate.

[0092] For example, the bottom of the second support column 300 may be close to the arc-shaped third support plate 204 , so that the third support plate 204 can provide a higher support strength to the second support column 300 .

[0093] It should be noted that, during the process of forming the first support column 200 through the injection molding process, the arc-shaped third support plate 204 can evenly distribute the liquid injection material, thereby making the thickness of the third support plate 204 uniform, effectively improving the support strength of the third support plate 204 .

[0094] In the second case, please refer to Figure 10 The third support plate 204 may include a planar support plate 2041 and arc-shaped support plates 2042 located on both sides of the planar support plate 2041 .

[0095] For example, the arc-shaped support plates 2042 on both sides of the flat support plate 2041 can serve as chamfers. On the one hand, the arc-shaped support plates 2042 can ensure that the thickness of the third support plate 204 is uniform. That is, the arc-shaped support plates 2042 are the same thickness as the flat support plate 2041, and the same thickness as the first support plate 201 and the second support plate 202. This ensures that the strength of the connection between the first support column 200 and the carrier body 100 is relatively uniform. On the other hand, the arc-shaped support plates 2042 in the third support plate 204 bring the connection between the connecting plate 203 and the second support column 300 closer to the arc-shaped support plates 2041, thereby allowing the third support plate 204 to provide better support for the second support column 300.

[0096] For the second implementation, please refer to Figure 12 , Figure 12 This is a cross-sectional view of a first support column provided in an embodiment. The first support plate 201 and the second support plate 202 in the first support column 200 are arranged in parallel. In this embodiment, the parallel arrangement of the first support plate 201 and the second support plate 202 may mean that the symmetry plane S1 of the first support plate 201 along its height direction and the symmetry plane S2 of the second support plate 202 along its height direction are arranged in parallel.

[0097] In this case, during the process of forming the first support column 200 using the first mold, a certain draft angle needs to be set to ensure smooth demolding of the first mold. Thus, in the first support column 200 obtained after the first mold demolding process, the thickness of the first support plate 201 and the thickness of the second support plate 202 both gradually decrease along the demolding direction of the first mold.

[0098] It should be noted that when the first support plate 201 and the second support plate 202 are arranged in parallel, the first support column 200 further includes a third support plate 204. The third connecting plate 204, the first support plate 201, and the second support plate 202 are all connected to the same side of the carrier body 100, and the third support plate 204 is respectively connected to the first support plate 201 and the second support plate 202. The thickness of the first support plate 201 and the thickness of the second support plate 202 both gradually decrease in a direction away from the third support plate 204.

[0099] For example, during the process of forming the first support column 200 using the first mold, more injection material is applied to the first and second support plates 201, 202 on the side closer to the third support plate 204, while less injection material is applied to the first and second support plates 201, 202 on the side farther from the third support plate 204. In this case, the opening between the first and second support plates 201, 202 gradually widens toward the third support plate 204, making it easier to eject the first mold 200b.

[0100] It should be noted that the structure and function of the third support plate 204 can refer to the corresponding structure and function of the third support plate 204 in the above text, and this application will not elaborate on this.

[0101] With respect to the two optional implementations described above, the thickness of the second support column 300 gradually decreases in a direction away from the first support column 200. The reason why the thickness of the second support column 300 gradually decreases in a direction away from the first support column 200 can be referred to the corresponding content in the above embodiments, and will not be further elaborated in this embodiment of the present application.

[0102] In the embodiment of the present application, because the draft direction of the first mold is perpendicular to the height direction of the first support column 200, the first mold has little effect on the strength of the first support column 200. Thus, the height of the first support column 200 can be greater than or equal to the height of the second support column 300, ensuring that the first support column 200 and the second support column 300 effectively support the display panel.

[0103] For example, the maximum height of the second support column 300 can be 30 mm, and the maximum height of the first support column 200 can be in the range of 40 mm to 60 mm. Thus, the maximum height of the entire support column structure 000 can be in the range of 70 mm to 90 mm.

[0104] Optionally, the shape of the second support column 300 may be a thin-walled hollow cylinder or a thin-walled H-shape, which is not limited in this application.

[0105] In the present application, the minimum thickness of the first support column 200 is greater than the maximum thickness of the second support column 300. In this way, it can be ensured that the first support column 200 has sufficient support strength for the second support column 300, and the thickness of the second support column 300 is not too thick, resulting in insufficient strength at the connection between the second support column 300 and the first support column 200, thereby ensuring that the support column structure 000 has good support for the display panel.

[0106] In summary, embodiments of the present application provide a support column structure comprising: a first support column and a second support column positioned on a supporting body. During the process of forming the first support column using a first mold and the second support column using a second mold, the first mold's draft direction differs from the second mold's draft direction. Therefore, the orientation of the first groove of the first support column differs from the orientation of the second groove of the second support column. Thus, when the supporting body is a rear case, if the distance between the front of the rear case and the display panel is large, the display panel is supported by the combination of the first and second support columns, and the heights of the individual first and second support columns are both relatively small. This eliminates the need to ensure that the second support column has a greater thickness near the first support column while also being thicker at the end away from the first support column. This effectively increases the support strength of the second support column for the display panel and ensures a higher connection strength between the second support column and the first support column. Furthermore, during the process of forming the first support column using the first mold, the first mold's draft direction is perpendicular to the height direction of the first support column, thus ensuring a higher connection strength between the first support column and the rear case. In this way, the first supporting column and the second supporting column can effectively improve the supporting effect of the display panel, thereby effectively improving the reliability of the display device.

[0107] An embodiment of the present application further provides a method for manufacturing a support column structure. The method for manufacturing a support column structure may include: forming a first support column and a second support column on a carrying body.

[0108] The first support column is connected to one side of the supporting body, and the second support column is connected to a side of the first support column away from the supporting body.

[0109] A first groove is formed on a side surface of the first supporting column, and a second groove is formed on a side of the second supporting column away from the first supporting column.

[0110] Optionally, forming the first support column and the second support column includes:

[0111] After the first mold and the second mold are matched, pouring the injection molding material between the first mold and the second mold;

[0112] After the injection molding material between the first mold and the second mold is solidified, the first mold is subjected to a demolding process to form a first support column with a first groove, and the second mold is subjected to a demolding process to form a second support column with a second groove;

[0113] The draft direction of the first mold intersects with the draft direction of the second mold.

[0114] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific manufacturing process and principle of the first support column and the second support column described above can refer to the corresponding parts in the aforementioned structural embodiments of the first support column and the second support column, and will not be repeated here.

[0115] The present application also provides a display device, which can be any device with a display function, such as a monitor, a television, or a navigator. The display device may include: a display panel 000a and any support column structure 000 in the above embodiments.

[0116] Please refer to Figure 13 , Figure 13 1 is a cross-sectional view of a display device provided by an embodiment of the present application, wherein the support column structure 000 may be located between the display panel 000a and the carrier body 100, and the support column structure 000 is used to support the display panel 000a.

[0117] It should be noted that the support column structure 000 can directly provide support for the display panel 000a, or it can indirectly provide support for the display panel 000a. Providing support for the display panel 000a indirectly can be understood as: there are other structures between the support column and the display panel, and the support columns support the other structures, thereby indirectly supporting the display panel. For example, when the display panel 000a is an organic light emitting diode display panel, the support column structure 000 can directly provide support for the display panel 000a to prevent it from being deformed or damaged. In a specific embodiment, the side of the second support column 300 in the support column structure 000 away from the first support column 100 can be in direct contact with the display panel 000a, so that the support column structure 000 can directly provide support for the display panel 000a.

[0118] For example, for a liquid crystal display panel, a backlight module may also be included, and the support column provides support for the backlight module and the display panel as a whole to prevent them from being deformed or damaged. In a specific embodiment, when the display panel 000a is a liquid crystal display panel, the display device may further include: a backlight module located between the support column structure 000 and the display panel 000a. The backlight module can be connected to the display panel 000a (directly or through other mechanical structures), and the side of the second support column 300 in the support column structure 000 away from the first support column 100 can be in contact with the side of the backlight module away from the display panel 000a, so that the support column structure 000 can indirectly provide support for the display panel 000a.

[0119] In the examples of this application, please refer to Figure 5The side where the carrier body 100 is connected to the first support column 200 is an arc surface. The number of first support columns 200 and the number of second support columns 300 are both multiple. The multiple first support columns 200 are evenly arranged on the carrier body 100, and the multiple second support columns 300 are coplanar with a side away from the first support columns 200.

[0120] For example, the evenly distributed number of first support columns 200 and second support columns 300 can provide good support strength for the rear cover, making it less likely to deform under external forces. At the same time, the first support columns 200 and the second support columns 300, which are located away from the first support columns 200, are coplanar, ensuring that the support column structure 000 uniformly supports the display panel.

[0121] Optional, such as Figure 5 As shown, the carrier body 100 can be the back cover of the display device, which can be connected to the display panel 000a in the display device. For example, the edge area of ​​the back cover facing the display panel 000a has a plurality of first snaps 400 arranged in an array. At the same time, a plurality of second snaps 500 corresponding to the plurality of first snaps 400 are provided around the display panel 000a. In this way, when the plurality of first snaps 400 and the plurality of second snaps 500 are snapped in a one-to-one correspondence, the connection between the back cover and the display panel 000a can be achieved. After the back cover and the display panel 000a are connected, the support column structure 000 on the back cover can provide support for the display panel 000a.

[0122] In the related art, since the maximum height of the support column 02 in the related art is only 30 mm, the maximum distance between the rear housing and the display panel can only be 30 mm.

[0123] However, in product design, due to appearance design requirements or the need to use support columns to provide sufficient space to accommodate other structures or devices, the maximum distance between the back cover and the display panel needs to be greater than 30 mm. At this time, the support column 02 provided by the relevant technology cannot provide effective support for the display panel, which limits the product design.

[0124] In the embodiment of the present application, since the maximum height of the first support column 200 provided in the embodiment of the present application can be in the range of 40mm-60mm, and the maximum height of the second support column 300 can be 30mm, the overall height of the support column structure 000 composed of the first support column 200 and the second support column 300 can be in the range of 70mm-90mm, which is much greater than 30mm. Thus, in the embodiment of the present application, even if the curvature of the rear shell is large, resulting in a maximum distance between the rear shell and the display panel greater than 30mm, the support column structure 000 composed of the first support column 200 and the second support column 300 can still support the display panel, thereby ensuring that the support column structure 000 has a better support effect on the display panel and can provide more freedom in product design. In a specific embodiment, the rear shell of the display device is a curved rear shell, and the maximum distance between the rear shell and the display panel is greater than 30mm. The support columns provided in the embodiment of the present application can be used to meet the support requirements.

[0125] In some embodiments, the distance between the back cover and the display panel at different positions in the display device may be different. At some positions, the maximum distance between the back cover and the display panel is less than or equal to 30 mm. At other positions, the maximum distance between the back cover and the display panel is greater than 30 mm. Therefore, the support columns in the related art can be combined with the support columns provided in the embodiments of the present application to meet the support needs.

[0126] It should be noted that any of the above-mentioned supporting bodies 100 and supporting column structures 000 can be adapted to a flat display panel 000a or a curved display panel 000a, and this application does not limit this.

[0127] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It will also be understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer. In addition, it will be understood that when an element or layer is referred to as being "under" another element or layer, it may be directly under the other element, or there may be more than one intermediate layer or element. In addition, it will also be understood that when a layer or element is referred to as being "between" two layers or elements, it may be the only layer between the two layers or elements, or there may also be more than one intermediate layer or element. Similar reference numerals throughout the text indicate similar elements.

[0129] The above description is merely an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
