[0035] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0036] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0037] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0038] In the related art, the conventional frame design scheme of the display panel 10 ′ is as follows:

[0039] like Figure 1 As shown, after the frame is assembled, the middle frame 200' wraps the back plate 300', the outer frame 100' wraps the middle frame 200', and the outer frame 100' does not bulge outward; Figure 2 As shown, theoretically, the outer frame 100' has a rectangular shape.

[0040] However, if Figure 3 As shown, in reality, due to process tolerance and other reasons, the middle position of the outer frame 100' bulges slightly outward, resulting in the middle position of the long side of the outer frame 100' not being closely attached to the middle frame 200', forming a Figure 4 The bulging phenomenon shown causes the overall dimensions of the frame at this position to be NG.

[0041] Currently, the degree of bulging in the middle of the outer frame 100 ′ is generally controlled through process control so that the final size is within the tolerance range, but there is still a risk that the overall outer size of the frame will be NG.

[0042] In view of the above technical problems, the embodiments of the present disclosure provide a frame assembly for a display panel, such as Figures 5 to 9As shown, the frame assembly includes: an outer frame 100, a middle frame 200 and a back panel 300, the outer frame 100 includes a first buckling portion 110 and a first side wall portion 120, the middle frame 200 includes a second buckling portion 210 and a second side wall portion 220, the second buckling portion 210 is arranged opposite to the first buckling portion 110, and the second side wall portion 220 is arranged opposite to the first side wall portion 120; the back panel 300 includes a main body portion 310 and a third side wall portion 320, the main body portion 310 is arranged opposite to the second buckling portion 210, and the third side wall portion 320 is arranged opposite to the second side wall portion 220; the first side wall portion 120, the second side wall portion 220 and the third side wall portion 320 surround the main body portion 310.

[0043] Among them, the first side wall is provided with an inserting portion 130 extending toward the main body portion 310, and the second side wall portion 220 is provided with a first plugging hole, the inserting portion 130 extends into the first plugging hole and has an overlapping portion with the second side wall portion 220 in the direction facing the first side wall portion 120 and the second side wall portion 220; the second buckling portion 210 is provided with a second plugging hole, and the third side wall portion 320 is provided with an extending portion 330 toward the second buckling portion 210, and the extending portion 330 extends into the second plugging hole.

[0044] The frame assembly provided by the present disclosure includes three parts: an outer frame 100, a middle frame 200 and a back plate 300. The extension portion 330 on the third side wall portion 320 of the back plate 300 is inserted into the second plug hole on the second buckling portion 210 of the middle frame 200, so that the back plate 300 and the middle frame 200 are limitedly connected, thereby ensuring a tight fit; the plug-in portion 130 on the first side wall of the frame extends into the first plug hole of the second side wall portion 220, and has an overlapping portion with the second side wall portion 220 in the direction in which the first side wall portion 120 and the second side wall portion 220 face each other, so that the outer frame 100 and the middle frame 200 are limitedly connected, thereby ensuring a tight fit, so that the outer frame 100, the middle frame 200 and the back plate 300 are limitedly connected, thereby improving the problem of the outer frame 100 bulging and deforming outward.

[0045] Specifically, Figure 5 As shown, the frame assembly includes: an outer frame 100, a middle frame 200 and a back plate 300; Figure 6 As shown, a plug-in portion 130 extending toward the main body 310 is provided on the first side wall of the frame, a first plug hole and a second plug hole are provided on the second side wall 220 of the middle frame 200, and an extension portion 330 is provided on the third side wall 320 of the back plate 300.

[0046] like Figure 7As shown, during the assembly process of the outer frame 100, the middle frame 200 and the back plate 300, the back plate 300 and the middle frame 200 can be assembled together first; after the back plate 300 and the middle frame 200 are assembled, the third side wall portion 320 of the back plate 300 is located on the inner side of the second side wall portion 220 of the middle frame 200, and the extension portion 330 on the third side wall portion 320 of the back plate 300 is inserted into the second plug hole on the second buckling portion 210 of the middle frame 200.

[0047] like Figure 8 As shown, the outer frame 100 and the middle frame 200 are then assembled together; after the outer frame 100 and the middle frame 200 are assembled, the first side wall portion 120 of the outer frame 100 is located on the outside of the second side wall portion 220 of the middle frame 200, and the plug-in portion 130 on the first side wall portion 120 of the outer frame 100 is inserted into the first plug hole on the second side wall portion 220 of the middle frame 200, and finally the outer frame 100, the middle frame 200 and the back plate 300 are assembled.

[0048] Since the plug-in portion 130 is inserted into the first plug hole and has an overlapping portion with the second side wall portion 220 in the direction in which the first side wall portion 120 and the second side wall portion 220 face each other, when the outer frame 100 bulges toward the periphery of the first side wall portion 120, the plug-in portion 130 is limited by the second side wall portion 220 of the middle frame 200, thereby forming a limit for the outer frame 100 to bulge toward the periphery of the first side wall portion 120 through the plug-in portion 130. At the same time, when the second side wall portion 220 of the middle frame 200 is subjected to the pulling force when the outer frame 100 bulges outward, since the extension portion 330 of the back plate 300 is inserted into the second plug hole of the second buckling portion 210 of the middle frame 200, a limit for the movement of the middle frame 200 toward the periphery is formed through the extension portion 330 of the back plate 300, and finally the outer frame 100, the middle frame 200 and the back plate 300 are tightly assembled together, limiting the frame from bulging toward the periphery of the first side wall portion 120.

[0049] Among them, Fig. 9 As shown, after the outer frame 100, the middle frame 200 and the back plate 300 are assembled together, the first buckle part 110 of the outer shell, the second buckle part 210 of the middle frame 200 and the main body 310 of the back plate 300 are arranged in parallel to form a clamping of the edge of the panel body, thereby fixing the panel body. For example, the first buckle part 110 and the second buckle part 210 can be used to clamp and fix the cover plate of the panel body, and the second buckle part 210 and the main body 310 of the back plate 300 can be used to clamp and fix the display function layer, the driving function layer and the backlight source and other functional film layers of the panel body, and the present disclosure does not limit this.

[0050] In one embodiment, if Figure 7 and Fig. 9As shown, the first plug hole is connected with the second plug hole. By making the first plug hole connected with the second plug hole, only one plug hole 230 is required on the middle frame 200; when the outer frame 100 and the middle frame 200 are assembled, it is convenient for the plug-in portion 130 to be inserted into the through hole; after the outer frame 100, the middle frame 200 and the back plate 300 are assembled together, the plug-in portion 130 of the outer frame 100 and the third side wall portion 320 of the back plate 300 can be abutted together.

[0051] Of course, the first plug hole and the second plug hole may also be two independent plug holes, which are used to plug the extension portion 330 of the back plate 300 and the plug-in portion 130 of the outer frame 100 respectively, and the present disclosure does not limit this.

[0052] In one embodiment, if Figure 7 to Figure 9 As shown, a tongue is provided on the first side wall portion 120 , and the tongue serves as the plug-in portion 130 and extends into the plug-in hole 230 .

[0053] Among them, the tongue piece can be formed by a punching process on the frame, so that the plug-in part 130 and the first side wall part 120 can be an integrally formed structure, thereby improving the structural strength of the plug-in part 130; at the same time, by punching out the tongue piece as the plug-in part 130, the position accuracy of the tongue piece on the first side wall part 120 can be improved, thereby further improving the limiting effect on the outward bulging of the outer frame 100.

[0054] The tongue piece is bent toward one side of the second side wall portion 220. By bending the tongue piece toward one side of the second side wall portion 220, it is easy to insert the tongue piece into the through hole on the second side wall portion 220; at the same time, it can prevent the portion of the second side wall portion 220 where the tongue piece overlaps from protruding from the first side wall portion 120.

[0055] In the direction facing the first side wall portion 120 and the second side wall portion 220, the overlapping portion of the second side wall portion 220 and the plug portion 130 protrudes toward the side away from the first side wall portion 120 to form a protrusion 240. By providing the protrusion 240, the distance between the second side wall portion 220 and the third side wall portion 320 at this position is increased, which is equivalent to forming a space for accommodating the tongue piece between the protrusion 240 and the third side wall portion 320, thereby preventing the tongue piece from occupying the space of the third side wall portion 320, so that there is no need to make structural changes on the third side wall portion 320.

[0056] In the direction from the first side wall portion 120 to the second side wall portion 220, the distance between the surface of the protrusion 240 away from the tongue piece and the tongue piece is smaller than the distance between the surface of the first side wall portion 120 away from the tongue piece and the tongue piece. By making the distance between the surface of the protrusion 240 away from the tongue piece and the tongue piece smaller than the distance between the surface of the first side wall portion 120 away from the tongue piece and the tongue piece, the protrusion 240 is recessed relative to the outer surface of the first side wall portion 120 of the outer frame 100, and does not protrude from the outer surface of the first side wall portion 120.

[0057] In the direction from the first side wall portion 120 to the second side wall portion 220, the distance between the surface of the protrusion 240 away from the tongue and the tongue may also be equal to the distance between the surface of the first side wall portion 120 away from the tongue and the tongue. By making the distance between the surface of the protrusion 240 away from the tongue and the tongue equal to the distance between the surface of the first side wall portion 120 away from the tongue and the tongue, that is, the protrusion 240 is flush with the outer surface of the first side wall portion 120 of the outer frame 100, the side flatness of the frame is improved.

[0058] Of course, the protrusion 240 may be disposed protruding relative to the outer surface of the first side wall portion 120 of the outer frame 100 , and the present disclosure does not limit this.

[0059] In one embodiment, Figure 5 and Figure 6 As shown, the first side wall portion 120 of the outer frame 100 is annular. The annular outer frame 100 can surround the edge of the panel body to protect the panel body. Of course, the first side wall portion 120 can also be annular with an opening, or can be composed of multiple side wall portions arranged at intervals, which is not limited in the present disclosure.

[0060] Among them, Figure 5 and Figure 6 As shown, the first buckling portion 110 of the outer frame 100 is annular, and the annular first buckling portion 110 can surround the edge of the panel body to fix the panel body. Of course, the first buckling portion 110 can also be annular with an opening, or can be composed of multiple buckling portions arranged at intervals, which is not limited in the present disclosure.

[0061] In one embodiment, Figure 5 and Figure 6 As shown, the second side wall portion 220 of the middle frame 200 is annular. The annular middle frame 200 can surround the edge of the panel body to protect the panel body. Of course, the second side wall portion 220 can also be annular with an opening, or can be composed of multiple side wall portions arranged at intervals, which is not limited in the present disclosure.

[0062] Among them, Figure 5 and Figure 6As shown, the second buckling portion 210 of the middle frame 200 is annular, and the annular second buckling portion 210 can surround the edge of the panel body to fix the panel body. Of course, the second buckling portion 210 can also be annular with an opening, or can be composed of multiple buckling portions arranged at intervals, which is not limited in the present disclosure.

[0063] In one embodiment, Figure 5 and Figure 6 As shown, the third side wall portion 320 of the back plate 300 is annular. The annular third side wall portion 320 can surround the edge of the panel body to protect the panel body. Of course, the third side wall portion 320 can also be annular with an opening, or can be composed of a plurality of side wall portions arranged at intervals, which is not limited in the present disclosure.

[0064] In one embodiment, the frame assembly formed by the outer frame 100, the middle frame 200 and the back panel 300 is a polygon, and each side of the frame assembly is provided with at least one set of mating plug-in parts 130, first plug holes, second plug holes and extension parts 330.

[0065] like Figure 5 As shown, the outer frame 100, the middle frame 200 and the back plate 300 are respectively rectangular, and the outer frame 100, the middle frame 200 and the back plate 300 are assembled together to form a rectangular frame assembly. A plurality of groups of plug-in parts 130, first plug holes, second plug holes and extension parts 330 that fit together can be arranged on the four sides of the rectangular frame assembly as a connection structure, so as to prevent the first side wall part 120 of the outer frame 100 from bulging outwards.

[0066] Among them, the frame component formed by the combination of the outer frame 100, the middle frame 200 and the back panel 300 can also be circular, elliptical, triangular or irregular in shape, and multiple groups of plug-in parts 130, first plug holes, second plug holes and extension parts 330 that are matched together are distributed at intervals on the frame as connecting structures.
