In some embodiments, as shown in fig. 4-5, in order to prevent the light guide plate 4 from shaking randomly during transportation, a spacing column 221 is disposed between the first flange and the light guide plate 4. The spacers 221 are fixed to the chassis base 2 and are disposed toward the liquid crystal panel 7, and play of the light guide plate 4 on the chassis base 2 is restricted by the spacers 221.

When assembling, there is a gap between the limiting column 221 and the light guide plate 4 to prevent the light guide plate 4 from expanding due to heat when the display module is lit during operation. The gap between the limiting column 221 and the light guide plate 4 is a space reserved for the light guide plate 4 to expand when heated. Thereby preventing the light guide plate 4 from expanding due to too tight fit between the light guide plate 4 and the limiting pillars 221 so as to be in close contact with the limiting pillars 221, and causing the light guide plate 4 to be cracked or deformed, thereby avoiding the phenomenon of uneven brightness of the display module.

Due to the arrangement of the limiting columns 221, holes need to be punched in the bottom plate 2, and then riveting columns are riveted into the punched holes to form the limiting columns 221. In some embodiments, the rivet posts are riveted in from the rear side of the base plate 2 to form the retaining posts 221 arranged in a direction from the rear side to the front side of the base plate 2. Therefore, in the process of punching and riveting the stud into the hole, a part of protrusion in the direction from the rear side to the front side of the bottom plate 2 is formed at the edge of the hole, the part of protrusion affects the assembly between the light guide plate 4 and the limiting post 221, the hidden danger of scratching the light guide plate 4/the reflective sheet 3 exists, and the gap between the light guide plate 4 and the limiting post 221 is too large.

The arrangement of the recess 22 enables the part of the projection of the punched edge to be only positioned in the recess 22 and not higher than the body part 21, and the recess 22 is recessed towards the rear side of the bottom plate 2 relative to the body part 21, so that the punched edge of the light guide plate 4 arranged corresponding to the body part 21 can not be contacted with the light guide plate 4 during assembly and play, and the problem that the part of the projection of the punched edge can scratch the light guide plate 4 is solved.

In some embodiments, since there is no need to worry about the problem that the light guide plate 4 is scratched by the partial protrusion of the punched edge, there is no need to reserve a gap for the punched edge in the design process, so that the problem of causing an excessive gap between the light guide plate 4 and the position-limiting post 221 can be alleviated.

The bottom plate 2 is provided with at most two limiting posts 221 on the same side edge, in some embodiments, the bottom plate 2 is a quadrilateral bottom plate with four corners, two limiting posts 221 are respectively provided at the corners of the end portion of the bottom plate 2 where the side edge of the lamp strip 10 is placed, exemplarily, two limiting posts 221 are respectively provided at the corners of the end portion of the left side edge 26 of the bottom plate 2, and the side edge opposite thereto, that is, the right side edge 27 is not provided with the limiting posts 221. When the light guide plate 4 is affected by light and thermally expanded, the light guide plate 4 is expanded to abut against the limiting pillars 221 of the left side 26, and the limiting pillars 221 of the left side 26 are used for limiting the light guide plate 4 from continuously expanding to the left side, and simultaneously, the light guide plate 4 is promoted to expand to the right side. This reduces the problem of the strip 10 being pinched.

Referring to fig. 6 to 9, in some embodiments, in order to prevent the light guide plate 4 from being damaged by being pressed to the rear panel by expanding to the right, the concave portion 22 inside the corner formed by connecting the third flange and the second flange is a first concave portion, the concave portion 22 inside the corner formed by connecting the fourth flange and the second flange is a second concave portion, and the first concave portion and the second concave portion are respectively provided with the elastic bodies 13, that is, the elastic bodies 13 are provided at the corner of the end of the right side edge 27 of the light guide plate 4, and the elastic bodies 13 are located between the light guide plate 4 and the flange 23 to buffer the expansion of the light guide plate 4.

When the light guide plate 4 moves due to transportation or expands due to heat, one end of the light guide plate 4 abuts against the left-side limiting column 221, and the other end of the light guide plate 4 abuts against the elastic body 13, so that the elastic body 13 can be elastically deformed, and the movement and expansion of the light guide plate 4 are buffered. Thereby avoided light guide plate 4 because of the drunkenness that the transportation caused and the cracked or deformation of light guide plate 4 that the inflation caused, and then avoided causing the phenomenon that the display module shows bright dark inequality.

In some embodiments, the bottom plate 2 is also provided with recessed portions 22 corresponding to the positions of the elastic bodies 13, that is, the recessed portions 22 are disposed at the positions of four corners of the bottom plate 2, the recessed portions 22 are recessed toward the rear side of the bottom plate 2 relative to the body portion 21, and the elastic bodies 13 are disposed in the recessed portions 22 so as to reduce the overall thickness of the display module in the front and rear directions, so that the display module is more compact in internal structure and more attractive and exquisite in appearance.

The disconnected portions are located at the connection portions where the longitudinal elastic bodies 132 and the lateral elastic bodies 131 are connected. The partition 135 may enhance the connection strength of the connection between the transverse elastic body 131 and the longitudinal elastic body 132, and reduce the probability of the crack at the intersection of the surface of the second sidewall 1334 of the transverse elastic body 131 facing the light guide plate 4 and the surface of the second sidewall 1334 of the longitudinal elastic body 132 facing the first flange.

The transverse groove 1311 is formed with a first opening on an end surface of the transverse elastic body 131 away from the partition 135, so that the transverse groove 1311 communicates with the outside of the transverse elastic body 131 through the first opening in a direction parallel to the transverse flanges, and the longitudinal groove 1321 is provided with a second opening on an end surface of the longitudinal elastic body 132 away from the partition 135, so that the longitudinal groove 1321 communicates with the outside of the longitudinal elastic body 132 through the second opening in a direction parallel to the second flanges.

So that the second side wall 1334 and the first side wall 1333 have uniform wall thickness and uniform elastic deformation capability, thereby reducing concentrated stress at a certain position on the transverse elastic body 131 and avoiding the transverse elastic body 131 from generating cracks.

In some embodiments, the third sidewall 1336 and the fourth sidewall 1337 are parallel, and the fourth sidewall 1337 is parallel to a side of the light guide plate 4 close to the longitudinal elastic body 132, so that the light guide plate 4 can transmit the compressive force to the longitudinal elastic body 132 in a balanced manner when expanding, thereby reducing the concentrated stress at a certain position on the longitudinal elastic body 132 and avoiding the longitudinal elastic body 132 from cracking. The third side wall 1336 is located between the fourth side wall 1337 and the second flange of the back plate, so that a longitudinal groove 1321 is formed between the third side wall 1336 and the fourth side wall 1337, thereby improving the elastic deformability of the longitudinal elastic body 132.

In some embodiments, the side of the second substrate 1335 facing away from the longitudinal groove 1321 is fixed to the side of the recess 22 facing the liquid crystal panel 7, so that the longitudinal elastic body 132 is fixed in the recess 22, thereby reducing the thickness of the back plate of the display and making the display more beautiful.

In some embodiments, the extension of the longitudinal groove 1321 in the longitudinal direction is parallel to the extension of the second flap, the third side wall 1336 is located between the longitudinal groove 1321 and the second flap of the back plate, and the fourth side wall 1337 is located between the longitudinal groove 1321 and the light guide plate 4. So that the fourth side wall 1337 and the third side wall 1336 have uniform wall thickness and uniform elastic deformation capability, concentrated stress at a certain position on the longitudinal elastic body 132 is reduced, and cracks are prevented from being generated on the longitudinal elastic body 132.

In some embodiments, the recess direction of the groove 133 is the same as the recess direction of the recess 22. In the depression direction of the depression portion 22, the lowest point of the depression portion 22 is a valley 223, the lowest point of the groove 133 is a groove bottom 1331, the groove bottom 1331 is disposed close to the valley 223 relative to the plane of the main body portion 21, that is, the distance between the groove bottom 1331 and the valley 233 of the groove 133 is smaller than the distance between the plane of the main body portion 21 and the valley 233, taking the transverse elastic body 131 as an example, because the hardness of the solid first base 1332 is relatively hard, when the light guide plate 4 swells, the first base 1332 is prevented from contacting the light guide plate 4, and thus the deformation of the elastic body 13 and the buffering effect on the light guide plate 4 are improved.

In some embodiments, the plane of the groove bottom 1331 is the same as the plane of the main body 21, that is, the distance between the groove bottom 1331 of the groove 133 and the valley bottom 233 is equal to the distance between the plane of the main body 21 and the valley bottom 233, taking the transverse elastic body 131 as an example, because the solid first base 1332 has a relatively high hardness, when the light guide plate 4 expands, the first base 1332 is prevented from contacting the light guide plate 4, so that the deformation of the elastic body 13 and the buffering effect on the light guide plate 4 are improved.

In some embodiments, the groove bottom 1331 is disposed away from the valley floor 223 relative to the plane of the body portion 21, i.e., the distance between the groove bottom 1331 of the groove 133 and the valley floor 233 is greater than the distance between the plane of the body portion 21 and the valley floor 233. Since the deformation of the elastic body 13 and the buffering effect on the light guide plate 4 are enhanced due to the arrangement of the groove 133, even if the distance between the groove bottom 1331 of the groove 133 and the valley bottom 233 is greater than the distance between the plane where the body part 21 is located and the valley bottom 233, the deformation of the elastic body 13 and the buffering effect on the light guide plate 4 can be improved.

Because the light guide plate 4 corresponds this body part 21 and sets up, when the light guide plate 4 rocks or is heated the inflation at will when the transportation in order to extrude elastomer 13, the position that light guide plate 4 extrudes elastomer 13 all corresponds fluted 133, make elastomer 13's elastic force better, can be better provide the cushioning effect for light guide plate 4, avoided solid elastomer elasticity relatively poor, the hardness is harder and the problem that light guide plate 4 top that causes splits or warp, ensured display module's display effect.

On the one hand, under the same hardness, due to the arrangement of the grooves 133 in the elastic body 13, the elastic body 13 has good deformability during pressing of the light guide plate 4, and the generated interaction force is lower than that generated by a solid elastic body, so that not only can the light guide plate 4 be fixed, but also deformation of the light guide plate 4 caused by too large action force on the light guide plate 4 during expansion can be avoided.

In addition, compared with the design of the solid elastic body 13, the design of the groove 133 can use a material with higher hardness to facilitate the same interaction force, and taking the transverse elastic body 131 as an example, when the transverse elastic body 131 is pressed by the light guide plate 4, the force is transmitted to the back plate through the first base 1332 and/or the first side wall 1333 without the elastic body 13 itself generating larger deformation.

In some embodiments, the first side wall 1333 is proximate to the inside of the transverse cuff and the third side wall 1336 is proximate to the inside of the second cuff. So as to transmit forces to the backplate through the first side wall 1333 or the third side wall 1336.

In some instances, the first side wall 1333 and the inner side of the transverse flap are provided with a mating gap and/or the third side wall 1336 and the inner side of the second flap are provided with a mating gap. The light guide plate 4 can promote the elastomer 13 to removing to the direction that is close to turn-ups 23 when the inflation, and the setting in cooperation clearance is so that further reserves the inflation space for the inflation of light guide plate 4, avoids light guide plate 4 top to split.

In some embodiments, the tops of the first sidewall 1333 and the second sidewall 1334 do not exceed the plane of the light emitting surface of the light guide plate 4 and/or the tops of the third sidewall 1336 and the fourth sidewall 1337 do not exceed the plane of the light emitting surface of the light guide plate 4, so as to avoid the elastomer 13 interfering with the upper optical assembly. The light exit surface of the light guide plate 4 is a surface of the light guide plate 4 facing the liquid crystal panel 7.

In some embodiments, the elastomer may be disposed only on the short side away from the light strip 10 and not on the long side of the display module.

The light guide plate 4 is disposed corresponding to the main body 21, and a gap is formed between the light guide plate 4 and the elastic body 13 to prevent the light guide plate 4 from being expanded by heat when the display module is lit during operation. The gap between the elastic body 13 and the light guide plate 4 is a space reserved for thermal expansion of the light guide plate 4. Thereby prevent that light guide plate 4 that the cooperation of light guide plate 4 and elastomer 13 caused is too tight and light guide plate 4 inflation so that closely extrude with elastomer 13, lead to cracked or deformation of light guide plate 4, and then avoid causing the phenomenon that the display module assembly shows bright dark inequality.

In some embodiments, since the elastic body 13 can be elastically deformed, the light guide plate 4 and the elastic body 13 can be tightly connected to each other, so as to better limit the light guide plate 4.
