     Exemplary embodiments are described herein with reference to sectional views and/or plan views as idealized exemplary drawings. The exemplary embodiments should not be construed as being limited to the shapes shown herein, but include shape deviations due to, for example, manufacturing. 
     Some embodiments of the present disclosure provide a frame. As shown in  FIGS. 1A and 1B , and  FIGS. 2A and 2B , the frame  1  includes a support assembly  11 , two hemming brackets  12 , and at least two detachable fixing structures  13 . 
     The support assembly  11  extends in a first direction X, and the two hemming brackets  12  are respectively disposed at both sides of the support assembly  11  in the first direction X. Each hemming bracket  12  extends in a second direction Y, and an end of the hemming bracket  12  away from the support assembly  11  is a flanged portion  121 . The first direction X and the second direction Y are different, and a plane in which the first direction X and the second direction Y are located is perpendicular to a thickness direction Z of the frame  1 . In some embodiments, the first direction X is perpendicular to the second direction Y. 
     As shown in  FIGS. 2A and 2B , each hemming bracket  12  is fixed to a corresponding end of the support assembly  11  through at least one detachable fixing structure  13 . That is, one of the two hemming brackets  12  is fixed to one end of the support assembly  11  through at least one detachable fixing structure  13 , and the other of the two hemming brackets  12  is fixed to the other end of the support assembly  11  through at least one detachable fixing structure  13 . Accordingly, the two hemming brackets  12  are connected through the support assembly  11 . In some embodiments, the hemming bracket  12  is fixed to the corresponding end of the support assembly  11  through a plurality of detachable fixing structures  13 . 
     One of each hemming bracket  12  and the end of the support assembly  11  has at least one via hole K, and each detachable fixing structure  13  passes through one via hole K to be fixed to the other of each hemming bracket  12  and the end of the support assembly  11 . In some examples, as shown in  FIG. 2A , the hemming bracket  12  has at least one via hole K, and each detachable fixing structure  13  passes through one via hole K to be fixed to the end of the support assembly  11 . In some other examples, as shown in  FIG. 2B , the end of the support assembly  11  has at least one via hole K, and each detachable fixing structure  13  passes through one via hole K to be fixed to the hemming bracket  12 . In a case where the hemming bracket  12  is fixed to the corresponding end of the support assembly  11  through a plurality of detachable fixing structures  13 , in some examples, one of the hemming bracket  12  and the end of the support assembly  11  has one via hole K, and each detachable fixing structure  13  passes through the via hole K to be fixed to the other of the hemming bracket  12  and the end of the support assembly  11 . In some other examples, one of the hemming bracket  12  and the end of the support assembly  11  has a plurality of via holes K, the plurality of via holes K are in a one-to-one correspondence with the plurality of detachable fixing structures  13  and each detachable fixing structure  13  passes through a corresponding via hole K to be fixed to the other of the hemming bracket  12  and the end of the support assembly  11 . 
     There is a gap between an outer wall of the detachable fixing structure  13  and a hole wall of the via hole K, so as to enable the hemming bracket  12  and the support assembly  11  to move relatively when the support assembly  11  and the hemming bracket  12  are assembled, thereby adjusting a relative position between the hemming bracket and the support assembly  11 . In some embodiments, the hemming bracket  12  moves in the first direction X relative to the support assembly  11  when the support assembly  11  and the hemming bracket  12  are assembled, and after the adjustment of the relative position between the hemming bracket  12  and the support assembly  11 , the hemming bracket  12  and the support assembly  11  are completely locked through the detachable fixing structure  13 , so that a relative movement between the hemming bracket  12  and the support assembly  11  does not occur any more. 
     It will be noted that, a maximum distance that the hemming bracket  12  and the support assembly  11  may move relatively to each other may be set according to actual needs. Based on this, the set maximum distance may be achieved by reasonably setting a size of the via hole K and a size of the detachable fixing structure  13 . 
     When the frame  1  and a component to be fixed (e.g., a display assembly) are assembled, the component to be fixed is disposed at a side of the support assembly  11  in the thickness direction Z of the frame  1 , and flanged portions  121  of the two hemming brackets  12  are located at both sides of the component to be fixed in the first direction X. Each flanged portion  121  is opposite to one of two opposite side faces of the component to be fixed in the first direction X, so as to protect the side face. In some examples, a distance between the flanged portion  121  and the side face of the component to be fixed is less than or equal to a preset width. The preset width may be set according to actual conditions. For example, the preset width is less than or equal to 1 mm. Since the relative position of the hemming bracket  12  and the support assembly  11  in the first direction X is adjustable, a distance between the flanged portions  121  of the two hemming brackets  12  is adjustable. As a result, the distance between the flanged portion  121  and the side face of the component to be fixed may be adjusted, so that the distance may be adjusted to be within a desired range. Since there is an arrangement of the detachable fixing structure  13  in the frame  1 , when the frame  1  and the component to be fixed are assembled, the relative position of the hemming bracket  12  and the support assembly  11  in the first direction X may be adjusted at any time by operating the detachable fixing structure  13 . 
     In some embodiments, as shown in  FIGS. 2A and 2B , the hemming bracket  12  further includes a connection portion  122 , The connection portion  122  and the flanged portion  121  form an L-shaped structure. The connection portion  122  and the end of the support assembly  11  are stacked in the thickness direction Z of the frame  1 , and the at least one via hole K is disposed in one of the connection portion  122  and the end of the support assembly  11 . In some examples, as shown in  FIG. 2A , the at least one via hole K is disposed in the connection portion  122 , and each detachable fixing structure  13  passes through one via hole K to be fixed to the end of the support assembly  11 . In some other examples, as shown in  FIG. 2B , the at least one via hole K is disposed in the end of the support assembly  122 , and each detachable fixing structure  13  passes through one via hole K to be fixed to the connection portion  11 . 
     As shown in  FIG. 3 , in some examples, an angle formed by the connection portion  122  and the flanged portion  121  at a connection therebetween is an arc-shaped chamfering  124 . In this way, the connection portion  122  and the flanged portion  121  are smoothly transited at a connecting position, which avoids stress concentration, thereby improving structural performance. In addition, presence of burrs may also be avoided to prevent damage to the component to be fixed. 
     In some examples, as shown in  FIGS. 2A and 3 , the connection portion  122  includes a first connection sub-portion  1221  and a second connection sub-portion  1222 . The first connection sub-portion  1221  is located between the second connection sub-portion  1222  and the flanged portion  121 , and the first connection sub-portion  1221  is connected to the second connection sub-portion  1222  and the flanged portion  121 . The second connection sub-portion  1222  and the end of the support assembly  11  are stacked in the thickness direction Z of the frame  1 , and the first connection sub-portion  1221  and the support assembly  11  are non-overlapping in the thickness direction Z of the frame  1 . In embodiments in which the at least one via hole K is disposed in the connection portion  122 , the at least one via hole K is disposed in the second connection sub-portion  1222 . 
     In some embodiments, as shown in  FIG. 2A , at least one threaded hole is disposed at a surface of the end of the support assembly  11  facing the second connection sub-portion  1222  (for convenience of description, the threaded hole is hereinafter referred to as a first threaded hole  111 B). The detachable fixing structure  13  includes a fastener with a thread, and the fastener with the thread passes through one via hole K disposed in the second connection sub-portion  1222  to be fixedly connected to a corresponding first threaded hole  111 B. Herein, the first threaded hole  111 B may or may not penetrate the end of the support assembly  11 . 
     In some examples, the via hole K is a counter bore, and the fastener with the thread is placed in the counter bore. The fastener with the thread does not protrude out of a surface of the second connection sub-portion  1222  away from the support assembly  11 , so that an outer surface of the frame  1  at this position is flat. 
     In some other examples, the via hole K is a waist shaped hole, and a length of the via hole K in the first direction X is greater than a width of the via hole K in the second direction Y. 
     For example, the fastener with the thread is a bolt. The bolt includes a screw and a nut. The screw of the bolt extends into the first threaded hole  111 B after passing through the via hole K. By rotating the screw, a depth of the screw into the support assembly  22  gradually increases, and when a surface of the nut facing the screw is pressed against the second connection sub-portion  1222 , and a surface of the second connection sub-portion  1222  facing the support assembly  11  is also pressed against the support assembly  11 , the hemming bracket  12  is fixedly connected to the support assembly  11 . 
     As another example, the fastener with the thread is a double-end stud. The detachable fixing structure  13  further includes a nut, and the nut is sleeved on one end of the double-end stud. The other end of the double-end stud extends into the first threaded hole  111 B after passing through the via hole K. By rotating the screw, a depth of the double-end stud into the support assembly  22  gradually increases, and when a surface of the nut facing the support assembly  11  is pressed against the second connection sub-portion  1222 , and the surface of the second connection sub-portion  1222  facing the support assembly  11  is also pressed against the support assembly  11 , the hemming bracket  12  is fixedly connected to the support assembly  11 . 
     In some other embodiments, as shown in  FIG. 2B , the end of the support assembly  11  has at least one via hole K, and at least one second threaded hole  123  is disposed at a surface, of the connection portion  122  of the hemming bracket  12 , facing the end of the support assembly  11 . The detachable fixing structure  13  includes a fastener with a thread, and the fastener with the thread passes through one via hole K disposed at the end of the support assembly  11  to be fixedly connected to a corresponding second threaded hole  123 . Herein, the second threaded hole  123  may or may not penetrate the connection portion  122 . For an exemplary structure of the fastener with the thread, reference may be made to the above, which will not be repeated herein. 
     In some embodiments, as shown in  FIGS. 2A and 23 , the support assembly  11  has an upper surface  112  and a lower surface  113  disposed oppositely. A portion of the lower surface  113  at each end of the support assembly  11  is recessed toward the upper surface  112  relative to a portion of the lower surface  113  in a remaining region of the support assembly  11 . The second connection sub-portion  1222  is located at a side of the lower surface  113  of the support assembly  11 . That is, the end of the support assembly  11  has a cutaway groove, and the second connection sub-portion  1222  extends into the cutaway groove. The connection portion  122  has a top surface  122 A and a bottom surface  122 E that are disposed oppositely. A portion of the top surface  122 A at the second connection sub-portion  1222  is in contact with a portion of the lower surface  113  of the support assembly  11  at the end of the support assembly  11 . 
     In some examples, as shown in  FIG. 2A , the bottom surface  122 E of the connection portion  122  and the portion of the lower surface  113  of the support assembly  11  in the remaining region of the support assembly  11  are located in a same plane, and the plane is perpendicular to the thickness direction Z of the frame  1 . After the hemming bracket  12  and the support assembly  11  are assembled, the bottom surface  1223  of the connection portion  122  and the portion of the lower surface  113  of the support assembly  11  in the remaining region of the support assembly  11  constitute a lateral outer surface of the frame  1 , so that the lateral outer surface of the frame  1  is flat. In this way, the lateral outer surface of the frame  1  may be directly placed on a mounting table, and the frame  1  may be used as an assembly jig of the component to be fixed, so that additional jigs are reduced. 
     In some embodiments, as shown in  FIGS. 1A and 13 , the upper surface  112  of the support assembly  11  is an arc-shaped surface, an extending direction of an orthographic projection of each of curved sides C 112  of the arc-shaped surface on the plane in which the first direction X and the second direction Y are located is parallel to the first direction X, and the arc-shaped surface and the flanged portion  121  are located at the same side of the frame  1 . For example, the component to be fixed has a curved surface structure, and the arc-shaped surface may be suitably connected to the curved surface of the component to be fixed, and the flanged portion  121  protects a side face of the component to be fixed, so that the frame  1  may be applied to the component to be fixed with the curved surface structure. 
     In some examples, as shown in  FIG. 2A , a portion of the top surface  122 A of the connection portion  122  in the first connection sub-portion  1221  is an inclined surface, and the inclined surface is tangent to an edge of the arc-shaped surface of the support assembly  11  proximate to the inclined surface. In this way, the inclined surface and the edge of the arc-shaped surface may be smoothly transited without a sharp transition portion. Accordingly, when the component to be fixed is in contact with a transition portion of the inclined surface and the arc-shaped surface, the component to be fixed may not be scratched by the transition portion. 
     In some embodiments, as shown in  FIGS. 1A and 1B , the support assembly  11  includes at least one support member  111 , As shown in  FIGS. 1A, 1B, and 4 , each support member  111  is in an arcuate shape, and the upper surface  112  of the support member  111  is an arc-shaped surface. An extending direction of an orthographic projection of each of curved sides C 112  of the arc-shaped surface on the plane in which the first direction X and the second direction Y are located is parallel to the first direction X, and the arc-shaped surface and the flanged portion  121  are located at the same side of the frame  1 . 
     As shown in  FIG. 1A , in some examples, the support assembly  11  includes at least two support members  111 , and any two adjacent support members  111  of the at least two support members  111  are space apart in the second direction Y. An end of each support member  111  is fixed to one hemming bracket  12  through at least one detachable fixing structure  13 , and the other end is fixed to the other hemming bracket  12  through at least one detachable fixing structure  13 . Herein, the two hemming brackets  12  are connected through at least two support members  111  to form the frame  1  of a stable structure. 
     Based on this, in some examples, as shown in  FIG. 1A , the frame  1  further includes at least one bracket  14 , and each bracket  14  extends in the second direction Y. The at least one bracket  14  is disposed between the two hemming brackets  12 , and the at least one bracket  14  and the at least two support members  111  are fixedly connected. 
     In some examples, the at least one bracket  14  includes two brackets  14 , and the two brackets  14  are space apart in the first direction X. A distance between one bracket  14  and a corresponding hemming bracket  12  is equal to a distance between the other bracket  14  and the other corresponding hemming bracket  12 . 
     In some examples, as shown in  FIGS. 1A, 1B, and 4 , at least one opening  111 A is disposed on each support member  111 , and the at least one opening  111 A penetrates the support member  111  in the second direction Y. by providing the opening  111 A, the support member  111  may be hollowed out at a position where the opening  111 A is located, so as to reduce a weight of the support member  111  on the premise that a structural performance of the support member  111  is not affected. Moreover, the opening  111 A may be used as a storage space for other components, so as to increase a storage capacity of the frame  1 . In addition, the opening  111 A may be used as a heat-dissipating channel to increase a speed of heat dissipation and enhance a heat-dissipating capability of the frame  1 . 
     In some examples, as shown in  FIG. 1A , a plurality of mounting holes  15  are disposed on the support assembly  11 , the bracket  14  and the hemming brackets  12 . The plurality of mounting holes  15  and the flanged portions  121  are located at the same side of the frame  1 . In this way, by providing a plurality of protrusions on the component to be fixed, when the frame  1  and the component to be fixed are assembled, the connection between the frame  1  and the component to be fixed may be made tight by matching the plurality of protrusions into the plurality of mounting holes  15  in a one-to-one correspondence manner, which avoids local warping. 
     In some examples, the plurality of mounting holes  15  are uniformly distributed, so that a connection force between the frame  1  and the component to be fixed is uniformly dispersed, and stress concentration is avoided. 
     For example, as shown in  FIG. 1A , N mounting holes  15  are disposed on each hemming bracket  12 , and the N mounting holes  15  are spaced apart in the second direction Y. N mounting holes  15  are disposed on each bracket  14 , and the N mounting holes  15  are spaced apart in the second direction Y. All the mounting holes  15  on the hemming brackets  12  and the brackets  14  are arranged in N rows, and a plurality of mounting holes  15  in each row are spaced apart in the first direction X. In a case where the support assembly  11  includes at least two support members  111 , M mounting holes  15  are disposed on each support member  111 , and the M mounting holes  15  are spaced apart in the first direction X. All the mounting holes  15  on the support members  111  are arranged in M columns, and a plurality of mounting holes  15  in each column are spaced apart in the second direction Y. For example, N is 3 and M is 11. 
     Some embodiments of the present disclosure provide a display apparatus. As shown in  FIGS. 5 to 7 , the display apparatus  100  includes a display assembly  2  and the frame  1  described above. The display assembly  2  is the component to be fixed described above. 
     The display assembly  2  includes a display panel  21  and a backplate  22 . The backplate  22  is disposed on the support assembly  11  and is in contact with the support assembly  11 . The display panel  21  is located at a side of the backplate  22  away from the support assembly  11 . The two hemming brackets  12  are located at two edges of the display assembly  2  in the first direction X, and the flanged portion  121  of each hemming bracket  12  is opposite to one edge of the display assembly  2  in the first direction X to protect the edge. 
     The display panel  21  may be fixed to the backplate  22  in a variety of ways. For example, the display panel  21  bonds with the backplate  22  using an adhesive material. 
     In a case where a material of the backplate  22  is a metal conductive material, an insulating film layer is further disposed on a surface of the backplate  22  proximate to the display panel  21 , so as to prevent the backplate  22  from conducting electricity and affecting normal operation of the display panel  21 . The insulating film layer may be a film layer made of insulating tape or other insulating materials. In a case where the insulating film layer is double-sided tape, the display panel  21  may be directly disposed on the backplate  22  using the double-sided tape. 
     Since relative positions of the hemming brackets  12  and the support assembly  11  in the frame  1  in the first direction X may be adjusted, a distance between the flanged portion  121  and a side face of the display assembly  2  opposite to and proximate to the flanged portion  121  may be adjusted during a process of assembling the display assembly  2  and the frame  1 , so that the distance is adjusted to be within a desired range. 
     In some embodiments, the display assembly  2  is a curved display assembly. 
     In some examples, an extending direction of a side of a projection of the curved display assembly on a plane perpendicular to a thickness direction Z of the curved display assembly is parallel to the first direction X, and an extending direction of another side of the projection of the curved display assembly on the plane is parallel to the second direction Y, and the side and the another side are two adjacent sides of the projection of the curved display assembly on the plane. For example, an extending direction of long sides of the projection of the curved display assembly  2  on the plane is parallel to the first direction X, and an extending direction of short sides of the projection of the curved display assembly  2  on the plane is parallel to the second direction Y. As another example, an extending direction of a projection of each of curved sides of a surface of the curved display assembly  2  on the plane away from the frame  1  is parallel to the first direction X, and an extending direction of non-curved sides of the surface of the curved display assembly  2  away from the frame  1  is parallel to the second direction Y. 
     For the curved display assembly, both the display panel  21  and the backplate  22  are curved. In some examples, as shown in  FIG. 8A , the display panel  21  and the backplate  22  are assembled in a planar structure first. Then, when the display panel  21  and the backplate  22  that are assembled together are assembled with the frame  1 , the display panel  21  and the backplate  22  are bent to obtain the curved display assembly. Since materials of the display panel  21  and the backplate  22  are different, and characteristics of the display panel  21  and the backplate  22  are different, which leads to different deformation capacities of the display panel  21  and the backplate  22  during the bending process, so that the display panel  21  and the backplate  22  that are bent have certain misalignment on a side of the curved display assembly. Moreover, as bending degrees of the display panel  21  and the backplate  22  increase, the misalignment will become more and more serious. 
     For example, as shown in  FIG. 8B , the display panel  21  and the backplate  22  are bent downward. An extending direction of a projection of each of curved sides of a surface of the display panel  21  on the plane away from the frame  1  is parallel to the first direction X, and an extending direction of non-curved sides of the surface of the display panel  21  away from the frame  1  is parallel to the second direction Y. Since the deformation capacities of the display panel  21  and the backplate  22  are different during the bending process, there is a misalignment dx between a face of the display panel  21  and a corresponding face of the backplate  22  in the first direction X, so that the face of the display panel  21  cannot be aligned with the corresponding face of the backplate  22 . 
     Although the misalignment may be controlled during manufacturing of the display panel  21  and the backplate  22 , and a degree of the misalignment may be reduced to a certain extent, a phenomenon of the misalignment of the display panel  21  and the backplate  22  after bending is still inevitable because a curvature radius of the curved display assembly in actual bending and a curvature radius thereof in design cannot be completely matched. Meanwhile, misalignment degrees are poor in consistency, and different misalignments may be presented on different curved display assemblies. 
     As shown in  FIG. 7 , when the frame  1  in the embodiments of the present disclosure is used to be assembled with the curved display assembly, since the relative positions of the hemming brackets  12  and the support assembly  11  are adjustable, the relative positions of the hemming brackets  12  and the support assembly  11  may be adjusted according to actual situations of the curved display assembly, thereby adjusting a distance G 1  between the flanged portion  121  and the side face of the curved display assembly. As a result, the distance G 1  may be adjusted to be within a prescribed range, so that gaps on edges of different display apparatuses  100  are substantially equal to meet consistency requirements of industrial production. 
     In some embodiments, as shown in  FIGS. 9 and 10 , the display assembly  2  further includes two protection frames  3 . The two protection frames  3  are disposed at two edges, of the display assembly  2 , that are oppositely disposed in the second direction Y. Each protection frame  3  is in contact with one of two side faces, of the display panel  21 , that are oppositely disposed in the second direction Y. In this way, it is possible to reduce or eliminate a gap between the protection frame  3  and the side face of the display panel  21 , improve a reliability of the display apparatus  100 , and ensure an aesthetic appearance of the display device  100 . 
     In some examples, as shown in  FIG. 10 , the protection frame  3  includes a side frame  31  and an elastic clamping portion  32  connected to the side frame. The elastic clamping portion  32  is clamped into the edge of the display assembly  2  and the gap between the backplate  22  and the display panels  21 . The side frame  31  is in contact with the side face of the display panel  21 . The elastic clamping portion  32  may be elastically deformed, which generates elastic force enabling the elastic clamping portion  32  to be fixed in the gap and not to be separated from the gap. 
     In some examples, as shown in  FIG. 10 , the protection frame  3  further has a position-limiting platform  33  at an edge of a surface of the elastic clamping portion  32  away from the display panel  21 . An edge portion of the backplate  22  is disposed on the surface of the elastic clamping portion  32  away from the display panel  21 , and there is a gap dy between a side face of the backplate  22  located at the edge portion and a side wall of the position-limiting platform  33 . In this way, a squeeze between the protection frame  3  and the backplate  22  and a displacement of the protection frame  3  may be avoided, and a reliable contact between the protection frame  3  and the side face of the display panel  21  may be further ensured. 
     In some embodiments, as shown in  FIGS. 9 and 10 , the display assembly  2  further includes at least one first driving circuit board  4 , and the at least one first driving circuit board  4  is disposed at at least one edge of two edges, of the display panel  21 , that are oppositely disposed in the second direction Y. In some examples, the display assembly  2  includes a plurality of first driving circuit boards  4 . The plurality of first driving circuit boards  4  are disposed at one of the two edges, of the display panel  21 , that are oppositely disposed in the second direction Y. In some other examples, as shown in  FIG. 9 , the display assembly  2  includes a plurality of first driving circuit boards  4 . Some of the plurality of first driving circuit boards  4  is disposed at one of the two edges, of the display panel  21 , that are oppositely disposed in the second direction Y, and the rest of the plurality of first driving circuit boards  4  is disposed at the other of the two edges, of the display panel  21 , that are oppositely disposed in the second direction Y. 
     As shown in  FIG. 10 , each first driving circuit board  4  is located on a side of the display panel  21  proximate to the backplate  22  and extends beyond the edge of the display panel  21 . The first driving circuit board  4  is located among the side frame, the elastic clamping portion  32 , and the display panel  21 . In this way, it is possible to ensure that the first driving circuit boards  4  will not be exposed outside the display assembly  2 , thus the first driving circuit boards  4  may be protected, and a tidy and aesthetic appearance of the display assembly  2  is ensured. For example, the first driving circuit board  4  includes a first film  41  and a source driving integrated circuit (IC)  42  disposed on the first film  41 , and the source driving IC  42  is located on a surface of the first film  41  away from the display panel  21 . When the first driving circuit board  4  is fixed, an end of the first film  41  is fixed to a back side of the display panel  21  facing the backplate  22 , and a remaining portion of the first film  41  extends out of the display panel  21 , and is then reversely folded to the back side of the display panel  21 . 
     In some embodiments, as shown in  FIGS. 9 and 11 , the curved display assembly  2  further includes at least one second driving circuit board  5 , and the at least one second driving circuit board  5  is disposed at at least one of the two edges, of the display panel  21 , that are oppositely disposed in the first direction X. In some examples, as shown in  FIG. 9 , the display assembly  2  includes a plurality of second driving circuit boards  5 . The plurality of second driving circuit boards  5  are disposed at one of the two edges, of the display panel  21 , that are oppositely disposed in the first direction X. In some other examples, the display assembly  2  includes a plurality of second driving circuit boards  5 . Some of the plurality of second driving circuit boards  5  is disposed at one of the two edges, of the display panel  21 , that are oppositely disposed in the first direction X, and the rest of the plurality of second driving circuit boards  5  is disposed at the other of the two edges, of the display panel  21 , that are oppositely disposed in the first direction X. 
     As shown in  FIG. 11 , each second driving circuit board  5  is located on the side of the display panel  21  proximate to the backplate  22 , and an orthographic projection of the second driving circuit board  5  on the backplate  22  is located within a range of an orthographic projection of the display panel  21  on the backplate  22 . The second driving circuit board  5  does not extend beyond the edge of the display panel  21 , and is always shielded by the display panel  21  and the backplate  22 , and cannot be seen from the outside. Based on this, there is no need to design a corresponding structure at the flanged portion  121  of the hemming bracket  12  to shield and avoid the second driving circuit board  5 . For example, the second driving circuit board  5  includes a second film  51  and a source driving IC  52  disposed on the second film  51 , and the source driving IC  52  is located on a surface of the second film  51  away from the display panel  21 . 
     In some embodiments, as shown in  FIG. 1A , in a case where a plurality of mounting holes  15  are disposed on the frame  1 , as shown in  FIG. 12 , a plurality of protrusions  221  are disposed on a surface of the backplate  22  facing the support assembly  11 . The plurality of protrusions  221  are configured to cooperate with the plurality of mounting holes  15 , so that the frame  1  and the backplate  22  may be positioned quickly. For example, as shown in  FIG. 13 , the plurality of protrusions  221  are in a one-to-one correspondence with the plurality of mounting holes  15 , and each protrusion  221  may be inserted into one mounting hole  15  to form a shaft-hole type positioning relationship.
