Referring to fig. 2 to 5, the backplate assembly 200 may include a backplate body 210 and an elastic limiting member 220, the surface of the backplate body 210 is used for disposing the optical element 300, and at least a portion of the edge of the optical element 300 has a gap with the edge of the backplate body 210, the elastic limiting member 220 is disposed in the gap between the optical element 300 and the backplate body 210, so that the backplate body 210 may not only support the optical element 300, but also provide an expandable space when the components in the optical element 300 generate heat and generate thermal expansion.

It can be understood that opposite sides of the elastic limiting member 220 are respectively abutted against the edge of the backplate body 210 and the edge of the optical assembly 300, and one side of the elastic limiting member 220 facing the optical assembly 300 is provided with an elastic shrinking portion 223, so that when components in the optical assembly 300 are thermally expanded, the optical assembly 300 can generate pressure on the elastic limiting member 220, and thereby the elastic limiting member 220 is pressed to generate elastic deformation, that is, a gap between the edge of the backplate body 210 and the edge of the optical assembly 300 is reduced, so that the optical assembly 300 can be prevented from being cracked due to top expansion during thermal expansion.

It should be noted that, in the display device provided in the embodiment of the present application, the elastic limiting member 220 is disposed between the back plate body 210 and the optical component 300, so as to perform the limiting and supporting functions on the optical component 300, and provide a space for the thermal expansion of the optical component 300, and meanwhile, through the elastic contraction portion 223 on the elastic limiting member 220, the elastic limiting member 220 is ensured to have good compression performance, and the phenomenon of uneven brightness of the display device is avoided.

In some embodiments, the whole back plate body 210 may have a square structure, the back plate body 210 may also include a top side, a left side, a right side, and a ground side, each side of the back plate and each side of the display panel 100 may be arranged relatively, and the relative position relationship between the top side, the ground side, the left side, and the right side of the back plate is consistent with the display panel 100, which is not described herein again.

For example, the material used for the back plate body 210 may include, but is not limited to, metal or alloy such as iron, aluminum, copper, etc., or plastic material with sufficient strength, which is not limited in this embodiment of the present invention.

The specific manner in which the backplate body 210 and the optical assembly 300 are engaged by the elastic limiting member 220 will be described in detail below.

First, it should be noted that the optical assembly 300 supported by the backplane body 210 includes the aforementioned multiple optical elements, and when the elastic limiting member 220 is matched with the optical assembly 300, in an operating state, one or more of the multiple optical elements may generate thermal expansion, so as to compress the elastic limiting member 220.

Referring to fig. 3 to 5, in a possible implementation manner, a light source 310 may be disposed on a side of the backplane body 210 facing the display panel 100, the light source 310 is connected to the backplane body 210, the light guide plate 320 may cover a light emitting side of the light source 310, a shape of the light guide plate 320 is matched with a shape of the backplane body 210, and a gap is formed between at least one side edge of the light guide plate 320 and an edge of the backplane body 210.

For example, the light guide plate 320 and the back plate body 210 may be in the same direction, that is, the light guide plate 320 may also include a top side, a left side, a right side, and a ground side, respectively, and the relative position relationship of the top side, the ground side, the left side, and the right side of the light guide plate 320 is consistent with that of the back plate body 210, which is not described herein again.

It should be noted that, when it is required to provide a space for thermal expansion of the light guide plate 320, the gap between the edge of the light guide plate 320 and the edge of the back plate body 210 may be on any one or more of the top side, the bottom side, the left side and the right side, which is not particularly limited in the embodiment of the present application.

In some embodiments, the number of the elastic shrinkage parts 223 may be multiple, and the elastic shrinkage parts 223 may be distributed along the extending direction of the elastic limiting member 220, so that when the light guide plate 320 is thermally expanded, one side of the elastic limiting member 220 may be sufficiently compressed, thereby providing a space for the expansion of the light guide plate 320 and preventing the light guide plate 320 from being broken.

It can be understood that both the main body of the elastic limiting member 220 and the elastic shrinking portion 223 can have elasticity, that is, can generate elastic deformation and be compressed when the light guide plate 320 is thermally expanded, wherein the elastic shrinking portion 223 is disposed such that one side of the elastic limiting member 220 facing the light guide plate 320 is compressed first, and the arrangement of the plurality of elastic shrinking portions 223 can ensure the balance of the stress at each position where the light guide plate 320 abuts against the elastic limiting member 220.

It should be noted that the edges between the light guide plate 320 and the back plate body 210 may be parallel to each other, that is, the gap between the edges may be in a long strip shape, and the elastic shrinkage portion 223 extends along the width direction of the gap, that is, the elastic shrinkage portion 223 may extend toward the light guide plate 320, so as to form a convex light guide plate 320 structure on the side surface of the elastic limiting member 220.

In addition, the cross-sectional dimension of the elastic shrinkage part 223 along the extending direction thereof can be gradually reduced, so that the side of the elastic shrinkage part 223 facing the light guide plate 320 can be more easily compressed, and further the elastic limiting part 220 can have better elasticity, thereby further reducing the risk of cracking caused by the edge being stressed and expanded when the light guide plate 320 is thermally expanded.

For example, the adjacent elastic shrinkage parts 223 may be connected in sequence, and the plurality of elastic shrinkage parts 223 may form a saw-tooth structure on one side of the elastic limiting part 220 facing the light guide plate 320, so that when the elastic shrinkage parts 223 may be compressed and deformed, the plurality of elastic shrinkage parts 223 may abut against the light guide plate 320 at the same time, and the reliability of supporting the light guide plate 320 may be improved, thereby effectively preventing the light guide plate 320 from shaking during transportation or use.

It is noted that the cross-sectional shape of the elastic constrictions 223 may be triangular, i.e. as described in the above solutions, a plurality of elastic constrictions 223 form a saw-tooth like structure.

In addition, fig. 6 is a schematic diagram of a second structure of the elastic limiting element in the display device provided in the embodiment of the present application, and fig. 7 is a schematic diagram of a third structure of the elastic limiting element in the display device provided in the embodiment of the present application, as shown in fig. 6, a cross-sectional shape of the elastic contraction portion 223 may also be a semicircular shape or other shape with an arc surface, and has a larger contact area when the light guide plate 320 expands and abuts against the elastic contraction portion 223, or, as shown in fig. 7, a cross-sectional shape of the elastic contraction portion 223 may also be a trapezoid, and a top of the trapezoid elastic contraction portion 223 abuts against an edge of the light guide plate 320. The embodiment of the present application does not specifically limit the specific cross-sectional shape, the number of the elastic contractible portions 223 and the adjacent distance.

In a possible implementation manner, the number of the elastic limiting members 220 may be multiple, the elastic limiting members 220 may be distributed at intervals along the edge of the backboard body 210, the edge of the backboard body 210 has a flange, and the elastic limiting members 220 abut against the inner side of the flange.

It can be understood that, an abutting surface is formed on one side of the turned edge facing the light guide plate 320 on the back plate body 210, and when the elastic limiting element 220 is assembled, one side of the elastic limiting element 220 departing from the light guide plate 320 can be abutted with the abutting surface of the turned edge, so that when the light guide plate 320 is thermally expanded, an expandable space is defined by a gap between the turned edge and the edge of the light guide plate 320, and a situation of local compression is avoided.

For example, the flanges may be disposed around a circumferential part of the edge of the backplate body 210, so as to dispose the elastic limiting member 220 at a circumferential part of the backplate body 210, or the flanges may be disposed around the backplate body 210, so as to facilitate manufacturing and adjusting the disposition position of the elastic limiting member 220.

In some embodiments, the elastic limiting element 220 may be located at a corner of the back plate body 210, the elastic limiting element 220 may include a first extending section 221 and a second extending section 222 connected to each other, and the first extending section 221 and the second extending section 222 are respectively abutted against two adjacent side edges of the back plate body 210, so that the corner of the light guide plate 320 is limited, and the light guide plate 320 is well supported.

It can be understood that, for the square-structured backplane body 210 and the light guide plate 320, which both have four corners, and the corners of the two are in one-to-one correspondence, that is, the corners between the top side and the left side, the corners between the top side and the right side, the corners between the bottom side and the left side, and the corners between the bottom side and the right side are included, the elastic limiting element 220 may be disposed on one or more of the corners, which is not specifically limited in this embodiment of the present invention.

Illustratively, the ground side of the light guide plate 320 abuts against the ground side of the back plate body 210, and the elastic stoppers 220 are respectively located at the corner between the top side and the left side of the back plate body 210 and the corner between the top side and the right side of the back plate body 210, so that the light guide plate 320 is mainly supported by the ground side, and a compressible expansion space is left for the top side of the light guide plate 320.

When the ground side of the light guide plate 320 abuts against the ground side of the back panel body 210, the ground side of the light guide plate 320 may abut against the back panel body 210 and may expand in the direction of the top side when the light guide plate 320 thermally expands.

In addition, as can be understood by those skilled in the art, the first extension segment 221 and the second extension segment 222 of the elastic limiting member 220 may be integrally formed, that is, the first extension segment 221 and the second extension segment 222 are bent relatively, so that the elastic limiting member 220 is L-shaped, and furthermore, a gap or a thinning structure may be disposed at a connection position between the first extension segment 221 and the second extension segment 222, so as to prevent the first extension segment 221 and the second extension segment 222 from being bent relatively when the elastic limiting member 220 is installed.

As can be understood by those skilled in the art, the elastic contraction portion 223 of the elastic limiting member 220 is located at the side, and therefore does not occupy the space in the thickness direction of the back plate body 210, which is beneficial to the overall light and thin design of the backlight module, and the structure of the back plate body 210 does not need to protrude in the opposite direction away from the display panel 100, thereby reducing the thickness of the backlight module to a certain extent.

In the embodiment of the present application, the reflective sheet 330 and the optical film 340 in the optical assembly 300 may be stacked together with the light guide plate 320, the reflective sheet 330 may be located between the light source 310 and the light guide plate 320, and the optical film 340 may be located on the light emitting side of the light guide plate 320, so that the light emitted from the optical assembly 300 to the display panel 100 may meet the display requirement.
