Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments, in case at least two embodiments are combined together without contradiction.

Referring to fig. 1, fig. 1 is a schematic diagram of a display device in a related art when assembled. In the related art, a foam 510 is attached to an inner wall of the middle frame 30 of the display device 1, the foam 510 is used for abutting against the optical film 60 after the assembly is completed, and the optical film 60 is fixed by the film hanger 10 connected to the back plate 40. However, in the process of attaching the foam 510 to the middle frame 30, the allowed positional offset of the foam 510 is small, so that the foam 510 is easily attached to the middle frame (i.e. closer to the appearance M1 of the middle frame 30), and further, in the process of assembling the middle frame 30 and the back panel 40, the end of the film hanger 10 directly abuts against the foam 510 (as shown in fig. 1), so that the foam 510 is pressed and twisted (i.e. the thickness of the foam 510 in the Y-axis direction is reduced), and after the assembly is completed, the foam 510 cannot abut against or only a small part of the foam abuts against the optical film 60, so that light can pass through between the foam 510 and the optical film 60, thereby causing light leakage and affecting the overall visual effect.

Referring to fig. 2, fig. 2 is a schematic view illustrating a film hanger provided in an embodiment of the present application being mounted in a display device. The application provides a diaphragm hangers 10, above-mentioned light leak phenomenon can be overcome or weaken to diaphragm hangers 10. The diaphragm hangers 10 are used for fixing a to-be-fixed piece in the display device 1, the display device 1 can be a liquid crystal television, correspondingly, the to-be-fixed piece can be an optical diaphragm 60 in the liquid crystal television, of course, the diaphragm hangers 10 can also be applied to other display devices 1, and the display device 1 is only used as the liquid crystal television for exemplary illustration in the application.

Referring to fig. 2 to fig. 3, fig. 3 is a schematic view of a membrane hanger according to an embodiment of the present application. The membrane hangers 10 include a body portion 100 and a retaining arm 110. The body portion 100 is adapted to be fixed to a carrier (back panel 40). The limiting arm 110 is used for passing through the member to be fixed (the optical film 60) to carry the member to be fixed. The position limiting arm 110 is disposed opposite to the main body 100 and connected to the main body 100. The material of the membrane hangers 10 may be, but not limited to, stainless steel, plastic, etc.

The limiting arm 110 includes a first limiting portion 111 and a second limiting portion 112. One end of the first position-limiting portion 111 is bent and connected to the main body portion 100. The second position-limiting portion 112 is connected to the other end of the first position-limiting portion 111 in a bending manner, and the second position-limiting portion 112 is inclined toward the main body 100 relative to the first position-limiting portion 111. In other words, the opposite ends of the first position-limiting portion 111 are respectively bent and connected to the main body 100 and the second position-limiting portion 112, wherein the second position-limiting portion 112 is a free end of the position-limiting arm 110. The bending angle α of the first and

second stoppers

111 and 112 is greater than 90 °, and the value of α may be, but is not limited to, 150 °, 160 °, 140 °, 151 °, 135 °, and the like.

When the film hangers 10 provided in the present application are applied to the display device 1, the above-described light leakage phenomenon can be avoided or weakened. Specifically, if the position of the foam 510 attached to the middle frame 30 exceeds the allowable offset, in the process of assembling the middle frame 30 and the back plate 40, the first limiting portion 111 and the second limiting portion 112 are bent and connected, so that the end of the second limiting portion 112 can be kept away from the foam 510. Even there is great skew in the attached position of bubble cotton 510, bubble cotton 510 also only can the butt deviate from one side of this body part 100 at second spacing portion 112, and spacing portion 112 of second at this moment can play the guide effect for bubble cotton 510 slides along one side that spacing arm 110 kept away from this body part 100, thereby can not extrude bubble cotton 510 and lead to the thickness attenuate, after the assembly, bubble cotton 510 then can be abundant butt to optical diaphragm 60 on. Therefore, when the film hangers 10 provided by the application are applied to the display device 1, the light leakage phenomenon can be avoided or weakened, the performance of the display device 1 is improved, and moreover, the requirement on the attaching precision of the foam 510 can be reduced, so that the production efficiency is improved.

It can be understood that, by bending the first limiting portion 111 and the second limiting portion 112, the optical film 60 can be prevented from escaping from the Y-axis direction, that is, the second limiting portion 112 can block the optical film 60 in the Y-axis positive direction.

Referring to fig. 2 to 3, the main body 100 includes a first connecting portion 120 and a middle arm 130 sequentially bent and connected. The limiting arm 110, the first connecting portion 120, and the middle arm 130 are sequentially bent and connected to form a first groove C1, and the first groove C1 is used for accommodating the part-beam optical film 60. In other words, the position-limiting arm 110 and the middle arm 130 are disposed opposite to each other and on the same side of the first connecting portion 120, so as to jointly enclose the first groove C1 having a substantially U-shape, and a portion of the optical film 60 is accommodated in the first groove C1. It can be understood that, a portion of the optical film 60 accommodated in the first groove C1 is simultaneously shielded by the limiting arm 110, the first connecting portion 120 and the middle arm 130, so that the portion of the optical film 60 can be prevented from colliding with other components in the display device 1, and therefore, the arrangement is favorable for protecting the optical film 60.

Referring to fig. 3 to 4, fig. 4 is a schematic view illustrating a placement state of the display device shown in fig. 2 in an operating state. The diaphragm hanger 10 further comprises a reinforcing rib 160, and the reinforcing rib 160 is connected to the outer walls of the limiting arm 110 and the first connecting portion 120. In general, the display device 1 is a shape display picture as shown in fig. 4, the positive direction of the X-axis is the direction of gravity, and it can be seen from the figure that the optical film 60 is carried on the limiting arm 110 of the film hanger 10. It will be appreciated that the optical diaphragm 60 itself has a weight such that the stopper arm 110 has a tendency to bend toward the direction of gravity, i.e., the opening of the first groove C1 increases. If the limiting arm 110 is bent, the optical film 60 may be moved downward, and the optical film 60 at the lowest side of the display device 1 may be moved closer to the edge of the display device 1, thereby increasing the risk of light leakage. In this embodiment, the reinforcing rib 160 is connected to the outer walls of the limiting arm 110 and the first connecting portion 120 at the same time, so that the bending strength can be improved, the limiting arm 110 is not bent due to the weight of the optical film 60, the light leakage phenomenon can be avoided, and the performance of the display device 1 is improved.

Referring to fig. 5, fig. 5 is a schematic view of a membrane hanger according to another embodiment of the present application. Optionally, a groove C7 is formed at an inner wall of the bent portion of the position limiting arm 110 and the first connecting portion 120, and the groove C7 may be, but is not limited to, a circular groove C7, a rectangular groove C7, a trapezoidal groove C7, and the like.

It can be understood that, if the groove C7 is not provided, during the bending process of the limiting arm 110 and the first connecting portion 120 by using the bending tool, the material at the bending position of the limiting arm 110 and the first connecting portion 120 is extruded and deformed to protrude, and the direction and shape of the deformation are not controllable, and further, during the assembling or other shaking processes of the display device 1, the optical film 60 accommodated in the first groove C1 may be worn by the protruding deformation material, and if the wear is too much, the optical film 60 may fall off.

In this embodiment, the groove C7 may be formed before the bending process is performed on the arm 110 and the first connecting portion 120, so that during the bending process performed on the arm 110 and the first connecting portion 120, the material that is deformed by compression at the bent portion is accommodated in the groove C7, and the optical film 60 may not easily contact the deformed material, and therefore, the groove C7 serves to protect the optical film 60. Moreover, it will be appreciated that the groove C7 can also facilitate bending of the arm 110 and the first connecting portion 120.

Referring to fig. 6, fig. 6 is a schematic view of a diaphragm hanger according to another embodiment of the present application. The first position-limiting portion 111 includes a first sub-portion 1111 and a second sub-portion 1112. One end of the first sub-portion 1111 is bent and connected to the first connection portion 120. The opposite ends of the second sub-portion 1112 are connected to the first sub-portion 1111 and the second position-limiting portion 112 respectively. Further, the first sub-portion 1111, the second sub-portion 1112 and the second position-limiting portion 112 together form a notch C3, that is, in the Z-axis direction, the size of the first sub-portion 1111 is larger than the size of the second sub-portion 1112 and the second position-limiting portion 112.

In the prior art, the limiting arm 110 and the first connecting portion 120 connected by bending are usually formed by punching with a punch, however, the second limiting portion 112 on the limiting arm 110 is bent, so that it is not beneficial for the punch to perform bending processing on the limiting arm 110 and the first connecting portion 120, and after the bending processing, the second limiting portion 112 can prevent the punch from exiting from the formed first groove C1.

In the present embodiment, since the notch C3 is formed in the stopper arm 110, the punch can press the stopper arm 110 and the first connecting portion 120 from the position of the notch C3 while avoiding the second stopper portion 112, and thus the bending process can be performed easily on the stopper arm 110 and the first connecting portion 120.

The notch C3 may be formed in the middle of the stopper arm 110, may be formed in the end of the stopper arm 110, or both of these forms may coexist. The quantity of breach C3 can be one or the interval a plurality of that set up, when having the breach C3 that a plurality of intervals set up, a plurality of breach C3 department homoenergetic are punched for it is better, and easier to bend the effect.

Referring to fig. 7, fig. 7 is a schematic view of a diaphragm hanger according to another embodiment of the present application. A through hole C4 is opened at the bent portion of the limiting arm 110 and the first connecting portion 120, the through hole C4 penetrates through two opposite sides of the membrane hanging lug 10, and the through hole C4 is disposed corresponding to the second limiting portion 112.

As can be seen from the above description of the embodiment, the punch punches through the notch C3 to form the position limiting arm 110 and the first connecting portion 120 into a bent state, and it can be understood that the punch cannot directly punch through the bent connecting portion corresponding to the second position limiting portion 112.

In this embodiment, the through hole C4 is disposed at the bending connection portion corresponding to the second stopper 112, and the through hole C4 represents no material, which means that the through hole C4 does not need to be bent, and the punch can be pressed at the rest position where the through hole C4 is not disposed, in other words, the through hole C4 is disposed to avoid the situation that the punch cannot be pressed. Therefore, the through hole C4 is formed at the bent portion of the stopper arm 110 and the first connecting portion 120 and at a position corresponding to the second stopper portion 112, which facilitates the punch to punch the stopper arm 110 and the first connecting portion 120 into the bent state.

Referring to fig. 8, fig. 8 is a schematic view of a diaphragm hanger according to another embodiment of the present application. The body portion 100 further includes a second connecting portion 140 and a fixing arm 150. The middle arm 130, the second connecting portion 140, and the fixing arm 150 are sequentially bent and connected to form a second groove C2. In other words, the fixed arm 150 and the middle arm 130 are disposed opposite to each other and on the same side of the second connecting portion 140, so as to jointly enclose the second groove C2 having a substantially U-shape.

Further, the opening direction of the second groove C2 is opposite to the opening direction of the first groove C1. The second groove C2 is used to allow the diaphragm hanger 10 to be inserted into the back plate 40 through the second groove C2, that is, a part of the back plate 40 is accommodated in the second groove C2, so that the diaphragm hanger 10 is fixed on the back plate 40. It can be understood that the portion of the back plate 40 received in the second groove C2 is simultaneously shielded by the fixing arm 150, the second connecting portion 140 and the middle arm 130, that is, the movement of the membrane hanger 10 in three directions is limited, which is beneficial to the fixing of the membrane hanger 10.

Referring to fig. 8, the fixing arm 150 includes a first sub-fixing arm 151 and a second sub-fixing arm 152. One end of the first sub-fixing arm 151 is bent and connected to the second connecting portion 140. The second sub-fixing arm 152 is connected to an end of the first sub-fixing arm 151 away from the second connecting portion 140, that is, the second sub-fixing arm 152 is a free end of the fixing arm 150. The second sub-fixing arm 152 protrudes from the first sub-fixing arm 151 in a direction away from the stopper arm 110.

It will be appreciated that the fixing arm 150 has a tendency to bend away from the direction of gravity, i.e., the opening of the second groove C2 increases, under the influence of the gravity of the optical diaphragm 60 itself. If the fixing arm 150 is bent, the protrusion 421 on the back plate 40 may be separated from the fixing hole C5 on the fixing arm 150, and if the display device 1 shakes, the fixing arm 150 may be separated from the back plate 40, so that the display device 1 may not work normally.

In the present embodiment, the second sub-fixing arm 152 protrudes from the first sub-fixing arm 151 in a direction away from the limiting arm 110, so that the second sub-fixing arm 152 can abut against the middle frame 30, it can be understood that, since the second sub-fixing arm 152 already abuts against the middle frame 30, the fixing arm 150 can be prevented from being bent under the influence of the gravity of the optical film 60, and thus, the performance of the display device 1 can be guaranteed.

Referring to fig. 9 and 10 together, fig. 9 is a schematic exploded view of a diaphragm hanger and a back plate according to an embodiment of the present disclosure. Fig. 10 is a schematic view of the diaphragm hangers and backplate of fig. 9 after assembly. The fixing arm 150 has a fixing hole C5, and the fixing hole C5 is used for receiving the protrusion 421 on the back plate 40, so as to fix the membrane hanger 10 on the back plate 40. Specifically, a protrusion 421 is formed on one side of the back plate 40 facing the fixing arm 150, a fixing hole C5 matched with the protrusion 421 in size and shape is formed on the fixing arm 150, and the protrusion 421 is accommodated in the fixing hole C5, so that the diaphragm hangers 10 and the back plate 40 are fixed together. The fixing hole C5 may be a through hole or a counter hole. The shape of the fixing hole C5 may be, but is not limited to, circular, rectangular, oval, etc.

It should be noted that, in the following embodiments, please refer to the drawings and the description of the previous embodiments of the membrane hangers 10 in conjunction with the description of the membrane hangers 10 in the display device 1, and the same parts will not be described in detail.

The display panel 20 is used for displaying a picture. The middle frame 30 is a frame body at least partially exposed to the outside, and is used for carrying the display panel 20. The middle frame 30 includes an outer frame 310 and a carrier 320, which are connected to each other in a bent manner, wherein the outer frame 310 is exposed to the outside, and the carrier 320 carries the display panel 20.

Further, the back plate 40 and the middle frame 30 are fastened to form a receiving space. The electronic components in the display device 1 are all accommodated in the accommodating space, and therefore, the back plate 40 and the middle frame 30 are used for protecting and carrying the electronic components of the display device 1.

Further, one side of the isolating member 50 is bonded to the carrier 320, and the other side of the isolating member is abutted to the end of the optical film 60, so as to isolate the carrier 320 from the optical film 60 and avoid friction between the carrier 320 and the optical film 60. The partition 50 is farther from the outer frame 310 than the through hole C6. It should be noted that the spacer 50 has a certain compressibility so as to avoid damage to the optical film 60 when abutting against the optical film 60. The color of the spacer 50 may be black, gray, etc., which may be, but is not limited to, foam.
