The top of backplate lateral wall 14 is provided with first breach 151 towards opening one side, and the top of backplate lateral wall 14 extends towards the inside of display 1 in first breach 151 and forms bending plate 112, and the inside of display 1 refers to the one side that keeps away from the user when display 1 uses, is provided with first jack catch 1131 and the second jack catch 1132 that the interval was provided with towards bottom plate 13 direction in the one end that keeps away from backplate lateral wall 14 of bending plate 112.

In some embodiments of the present application, a limiting post is disposed on the bottom plate 13, and the limiting post is used to limit an end of the extension 36 near the first back plate wall 141, so as to limit the light guide plate 30 from moving toward a direction near the first back plate wall 141. The extension 36 is limited by the limiting post and the first sidewall extension 11, and limits the movement amount of the light guide plate 30 in the left and right directions.

In some embodiments of the present application, the other of the sidewalls of the light guide plate except the sidewall facing the light bar 70 is adhered with a reflective patch 90 for reflecting light toward the inside of the light guide plate 30. The light reaching the side wall of the light guide plate to which the reflection patch 90 is attached is reflected by the reflection patch 90 into the light guide plate 30. After light enters the light guide plate 30, diffuse reflection occurs in the light guide plate 30, a part of reflected light is emitted from other side walls except the side wall facing the light bar 70 in the side walls of the light guide plate, when the reflective patch 90 is attached to the other side walls except the side wall facing the light bar 70 in the side walls of the light guide plate, the reflective patch 90 can reflect the light emitted from the other side walls except the side wall facing the light bar 70 in the side walls of the light guide plate, so that the light is re-emitted into the light guide plate 30, and is emitted from the light emitting surface 32 after diffuse reflection again, so that the loss of light is avoided, the brightness of the light emitted from the light emitting surface 32 is increased, the dark band is reduced, and a display screen with uniform brightness can be seen by a user.

In some embodiments of the present application, a blank region 362 is disposed between the reinforcing dots 361 and the scattering dots 37, and a first width of the blank region 362 along the extension portion 36 is greater than a second width, where the second width is a width obtained by multiplying a distance between any two columns of the scattering dots 37 by three, so that the blank region 362 can separate the reinforcing dots 361 and the scattering dots 37.

In some embodiments of the present application, a blank area 362 is disposed between the reinforcing dots 361 and the scattering dots 37, and a first width of the blank area 362 in the extending direction of the extension portion 36 is greater than a thickness of the light guide plate 30, so as to avoid local excessive brightness caused by frequent diffuse reflection of light between the reinforcing dots 361 and the scattering dots 37.

In some embodiments of the present application, the third width of the reinforcing dots 361 and the scattering layer 81 in the extending direction of the extension portion 36 is smaller than the thickness of the light guide plate 30, so that the light is emitted toward the light emitting surface 32 while being diffusely reflected between the reinforcing dots 361 and the scattering layer 81.

In some embodiments of the present application, the scattering dots 37 are distributed in a non-uniform array on the bottom surface 31 of the light guide plate body 35 on the side facing the bottom plate 13, and the diameter of the scattering dots 37 on the side near the first back plate wall 141 is smaller than the diameter of the scattering dots 37 on the side far from the first back plate wall 141. The side of the light guide plate 30 close to the first back plate wall 141 receives more light, the side of the light guide plate 30 far away from the first back plate wall 141 receives less light, and the smaller diameter of the scattering dots 37 on the side close to the first back plate wall 141 can meet the brightness requirement of the light, so that the excessive brightness is avoided; the larger diameter of the scattering dots 37 at the side far from the first back plate wall 141 can enhance diffuse reflection to increase brightness, thereby making the brightness of the display screen uniform.

In some embodiments of the present application, the reinforcing dots 361 include first reinforcing dots 3611 and second reinforcing dots 3612, the distance between the first reinforcing dots 3611 and the first back plate wall 141 is smaller than the distance between the second reinforcing dots 3612 and the first back plate wall 141, the diameter of the first reinforcing dots 3611 is larger than the diameter of the second reinforcing dots 3612, so that the light is more diffusely reflected at the first reinforcing dots 3611, and the light is less diffusely reflected at the second reinforcing dots 3612, so that the brightness of the picture is uniform.

In some embodiments of the present application, the diameter of the first reinforcing dots 3611 of the reinforcing dots 361 adjacent to the first back plate wall 141 is greater than the diameter of the first scattering dots 37, and the distance between the first reinforcing dots 3611 and the first back plate wall 141 and the distance between the first scattering dots 37 and the first back plate wall 141 are the same, so that more diffuse reflection of light occurs at the first reinforcing dots 3611, and the luminance at the extension portion 36 is prevented from being too low.

In some embodiments of the present application, the bottom plate 13 is provided with a recess 132 recessed toward a direction away from the light guide plate 30 at a position of the limiting post, so that the light guide plate 30 is conveniently limited by the limiting post.

In some embodiments of the present application, the light bar 70 of the display 1 is disposed on the inner side of any one of the back panel side walls 14, and is connected to the back panel side wall 14, so as to provide a light source for the display 1, and typically, an LED lamp is used as the light source.

In some embodiments of the present application, since the notch 38 of the light guide plate 30 extends to the fourth light guide plate sidewall 334 of the light guide plate 30, the first sidewall extension 11 can only limit the light guide plate 30 in one direction, in order to enhance the fixing of the light guide plate 30, the scattering layer 81 may be an adhesive layer, and the scattering layer 81 adheres to the extension 36 and the bottom plate 13, so that the extension 36 of the light guide plate 30 is fixed on the bottom plate 13, and the display screen fluctuation caused by the displacement of the light guide plate 30 is reduced. In some embodiments, the scattering layer 81 is an optical adhesive, which can adhere the bottom surface 31 of the light guide plate 30 to the bottom plate 13, so as to reduce the displacement of the light guide plate 30 relative to the bottom plate 13.

In some embodiments, since the light emitted from the surrounding scattering dots 37 to the middle area of the light guide plate 35 is contained directly above the scattering dots 37, the reflective patch 90 on the second slit sidewall 382 at the position of the slit 38 can make the light reflected from the light guide plate 30 directly above the scattering dots 37 at the position of the edge of the plate close to the slit 38 due to the reflective sheet 20, thereby achieving the effect similar to that of the middle area of the plate.

In some embodiments, the extension parts 36 are arranged, so that a part of the light inside the light guide plate body 35 near the extension parts 36 is scattered by the scattering dots 37 at the edge of the light guide plate body 35, and then enters the extension parts 36, and the extension parts 36 are provided with the scattering layer 81 and/or the reinforcing dots 361, so that the scattering dots 37 originally positioned at the edge inside the light guide plate body 35 obtain a scattering environment similar to the scattering dots 37 in the middle area of the light guide plate body 35, thereby reducing the uneven light emitting condition of the light emitting side of the light guide plate 30, and ensuring that the liquid crystal panel 60 has good display uniformity.

In some embodiments, the enhanced dots 361 and/or the scattering layer 81 are directly arranged according to the arrangement of the scattering dots 37, which may result in uneven light output at the positions of the extended portions 36 and the positions of the cutouts 38, and the white setting between the scattering dots 37 of the enhanced dots 361 improves the uniformity of light output at the positions of the extended portions 36 and the positions of the cutouts 38, so that the panel display uniformity is good.

In accordance with the present application, in some embodiments, the back plate sidewall 14 is provided with a second notch 152 at the top of the side facing the opening in the non-snapped and position of the back plate sidewall 14. Wherein the back side wall 14 is not a position on the back side wall 14 that is different from the position and card of the back side wall 14, and the position and card of the back side wall 14 refers to a position on the back side wall 14 where the structure for the card and the glue frame 50 is provided. The distance between the top of the back plate side wall 14 in the second notch 152 and the plane of the bottom plate 13 is smaller than the distance between the bearing part 52 and the plane of the bottom plate 13, so that the bearing part 52 and the top of the back plate side wall 14 in the second notch 152 have a gap, the probability of collision between the bearing part 52 and the top of the back plate side wall 14 in the second notch 152 can be reduced, the probability of damage to the top of the bearing part 52 and the top of the back plate side wall 14 of the second notch 152 due to collision can be reduced when the display 1 is impacted by the outside in the transportation process, and the display 1 is safer and more stable in the transportation process. The second notch 152 is located on the third back panel wall 143.

The top of the back-plate sidewall 14 in the second notch 152 extends towards the light guide plate sidewall to form an extension 121, where the light guide plate sidewall is a sidewall between the light-emitting surface 32 of the light guide plate 30 and the bottom surface 31 provided with the scattering dots 37. The extension portion 121 is used for limiting the light guide plate 30, and the light guide plate side wall is disposed on the side of the extension portion 121 close to the inside of the back plate 10, and the extension portion 121 can limit the light guide plate 30 on the side of the extension portion 121 close to the inside of the back plate 10, so that the movement amount of the light guide plate 30 in the direction of the outside of the back plate 10 can be reduced. The side surface of the light guide plate side wall and the side surface of the extension part 121, which are close to the back plate 10, are provided with gaps, so that the probability of damage caused by collision of the light guide plate side wall and the extension part 121 in the transportation process is reduced, and meanwhile, the side surface of the extension part 121, which is close to the back plate 10, can be prevented from being extruded when the light guide plate 30 is heated and expanded, so that the light guide plate 30 can be safely arranged on one side of the extension part 121, which is close to the back plate 10.

On both sides of the extension 121, the top of the back plate sidewall 14 in the second notch 152 extends toward the bearing portion 52 to form a baffle plate, which can limit the diaphragm 40 to the side of the baffle plate facing the inside of the back plate 10, and prevent the diaphragm 40 from moving to the side of the back plate 10 facing the outside.

The second side extension includes an extension 121 and a baffle.

The light guide plate 30 is disposed at a side of the bottom plate 13 facing the bearing portion 52, so that the light guide plate 30 is limited in the accommodating space by the bottom plate 13.

The diaphragm 40 is disposed on the light-emitting side of the light guide plate 30, and can further uniformly transmit the light emitted from the light guide plate 30, and the diaphragm 40 has light transmittance, so that the light emitted from the light guide plate 30 is converted into a soft surface light source through the uniform effect of the diaphragm 40 and is irradiated onto the liquid crystal panel 60, and the viewing experience of a user for viewing the display screen of the liquid crystal panel 60 can be improved.

The diaphragm 40 includes a main body 42 and a third extending plate 431 provided at an edge of the main body 42, the main body 42 being a main plane located in the middle of the diaphragm 40, and the third extending plate 431 being formed by the edge of the main body 42 protruding toward the back plate sidewall 14.

The width of the third extension plate 431 is matched with the width of the extension part 121, and the third extension plate 431 is disposed at a side of the extension part 121 facing the bearing part 52, so that the third extension plate 431 is mounted on the extension part 121.

Because the two sides of the extension part 121 are provided with the baffle extending towards the direction of the bearing part 52, the two sides of the third extension plate 431 are limited by the baffle, so that the third extension plate 431 cannot move leftwards and rightwards, the diaphragm 40 cannot move leftwards and rightwards, the limiting of the diaphragm 40 is realized, the structure is simple, the hanging structure is not additionally increased, the size of the diaphragm 40 is reduced, the additional rivet is not required, and the cost is saved.

In some embodiments of the present application, the barrier includes a first barrier 1221 and a second barrier 1222, and the first barrier 1221 and the second barrier 1222 are connected to both sides of the extension part 121, respectively, such that the third extension plate 431 provided at a side of the extension part 121 facing the carrier part 52 is limited between the first barrier 1221 and the second barrier 1222 to achieve limiting of the third extension plate 431 of the membrane 40 in the left and right directions.

The first baffle 1221 includes a first extension 12211 and a first blocking plate 12212 disposed toward the carrier 52 attached to an end of the first extension 12211 remote from the back plate sidewall 14. The second baffle 1222 includes a second extension 12221 and a second blocking plate 12222 disposed toward the carrier 52 connected to an end of the second extension 12221 remote from the backplate sidewall 14.

The first extension portion 12211 and the second extension portion 12221 are respectively formed by extending the top of the back plate sidewall 14 in the second notch 152 toward the light guide plate sidewall, and the first extension portion 12211 and the second extension portion 12221 are respectively connected to two sides of the extension portion 121. When the first baffle 1221 is impacted, the first extension 12211 provides a cushioning effect between the first baffle 12212 and the back plate sidewall 14 within the second gap 152, such that the first baffle 12212 is less likely to break due to the impact, as the first extension 12211 extends in the direction of the light guide plate sidewall. Similarly, the second extension 12221 also provides a cushioning effect between the second blocking plate 12222 and the back plate sidewall 14 in the second notch 152, so that the second blocking plate 12222 is not easily broken by force, and the operation safety and stability of the display 1 are improved.

In some embodiments, since the extension 121, the first baffle and the second baffle 1222 are formed on the top of the back-plate sidewall 14, if the first baffle 1221 is not provided with the first extension 12211 extending toward the inside of the display 1, the first baffle 1221 will not bend away from the display 1, because the peripheral portion of the back-plate sidewall 14 is provided with the fixing portion 51 of the bezel 50 and extends only from the top of the back-plate sidewall 14 directly toward the liquid crystal panel 60, and the length design of the extension direction of the third extension plate 431 is limited by the fixing portion 51 of the bezel 50 and will not extend out of the plane of the back-plate sidewall 14. This means that the stop plate can only be limited at the end of the third extension plate 431 at a position corresponding to the thickness of the stop plate. When the diaphragm 40 tends to move, the torque of the third extension plate 431 at the position of the stopper is large, and deformation is likely to occur. After the first baffle 1221 is provided with the first extension portion 12211 extending toward the inside of the display 1, the first blocking plate 12212 is provided at the end of the extension portion, and the position of the first blocking plate 12212 is increased compared to the distance of the third extension plate 431 away from the end of the main body of the diaphragm 40, so that the torque of the third extension plate 431 at the limiting portion is greatly reduced.

In some embodiments of the present application, the membrane 40 further includes a fourth extension plate 432 disposed at an edge of the main body 42, and the fourth extension plate 432 includes a first side extension plate 4321 and a second side extension plate 4322, where the first side extension plate 4321 and the second side extension plate 4322 are respectively connected to two sides of the third extension plate 431.

When the diaphragm 40 is mounted to the back plate 10, the first side extension plate 4321 is provided on the side of the first barrier plate 12212 facing the light guide plate sidewall, and the second side extension plate 4322 is provided on the side of the second barrier plate 12222 facing the light guide plate sidewall. The first side extension plate 4321 is limited by the first blocking plate 12212, and the second side extension plate 4322 is limited by the second blocking plate 12222, so that the diaphragm 40 is limited inside the back plate sidewall 14, and the movement amount of the diaphragm 40 to the outside of the back plate 10 side is reduced.

The extension length of the fourth extension plate 432 is smaller than the extension length of the third extension plate 431. The projected extension length of the first extension 12211 of the first baffle 1221 and the second extension 12221 of the second baffle 1222 on the bottom plate 13 are each smaller than the projected extension length of the extension 121 on the bottom plate 13, so that the first and second baffles 1221 and 1222 are mated with the fourth extension plate 432.

When the diaphragm 40 is mounted to the back plate 10, the first side extension plate 4321 and the first barrier 1221 have a gap therebetween, and the second side extension plate 4322 and the second barrier 1222 have a gap therebetween, which reduces the degree of close contact between the first side extension plate 4321 and the first barrier 1221, and reduces the probability of the first side extension plate 4321 colliding with the first barrier 1221 during transportation to cause breakage of the diaphragm 40. Similarly, the gap between the second side extension plate 4322 and the second baffle 1222 can reduce the probability of the second side extension plate 4322 and the second baffle 1222 colliding to cause the membrane 40 to break.

In some embodiments, since the first blocking plate 12212 and the second blocking plate 12222 are closer to the inside of the display 1 than the back plate sidewall 14 and are disposed along the light emitting direction of the light guide plate 30, the light emitted from the light guide plate 30 obliquely outside increases the local brightness after being reflected by the inner side surfaces of the first blocking plate 12212 and/or the second blocking plate 12222, and the light is homogenized and scattered before impinging on the inner side surfaces of the first blocking plate 12212 and/or the second blocking plate 12222 by the fourth extending plate 432, so as to reduce the local brightness variation.

In some embodiments of the present application, the width of the fourth extension plate 432 is not smaller than the width of the baffle, so that the fourth extension plate 432 can be stably limited on the side of the baffle close to the side wall of the light guide plate by the baffle, and the possibility that the limiting action of the baffle is disabled due to too small width of the fourth extension plate 432 is reduced. The film 40 is disposed on the light-emitting side of the light guide plate 30, and the width of the fourth extension plate 432 is not smaller than that of the baffle, so that light leakage between the baffle and the fourth extension plate 432 is prevented. The width of the fourth extension plate 432 is the projection width of the fourth extension plate 432 on the back plate sidewall 14, and the width of the baffle is the width extending along the back plate sidewall 14 direction.

In some embodiments of the present application, a reflective sheet 20 is disposed between the light guide plate 30 and the bottom plate 13, a distance between a plane in which the extension portion 121 is located and a plane in which the bottom plate 13 is located is D1, a thickness of the light guide plate 30 is H1, and a thickness of the reflective sheet 20 is H2, where d1 is equal to or less than h1+h2.

The extending portion 121 is located at a side of the bottom plate 13 facing the carrying portion 52, and when d1 is equal to or less than h1+h2, the distance between the light emitting surface 32 of the light guide plate 30 and the plane of the bottom plate 13 is not less than the distance between the plane of the extending portion 121 and the plane of the bottom plate 13, so that the side wall of the light guide plate is limited by the side surface of the extending portion 121, which is close to the side wall of the light guide plate, so that the light guide plate 30 cannot move in the direction of the outer portion of the back plate side wall 14 of the second notch 152, and the fluctuation degree of the display screen caused by the movement of the light guide plate 30 is reduced.

In some embodiments of the present application, the distance between the top of the baffle and the plane of extension 121 is D2, and the thickness of single diaphragm 40 is H3, H3. Ltoreq.D2. Since the diaphragms 40 are defined on the side of the baffle facing the side wall of the light guide plate, at least one diaphragm 40 is limited by the baffle when H3. Ltoreq.D2. In some embodiments, the plurality of films 40 are overlapped and defined on the side of the baffle facing the sidewall of the light guide plate, and the plurality of films 40 are overlapped to make the light emitted from the films 40 to the liquid crystal panel 60 more uniform, so as to improve the visual experience of the user for viewing the liquid crystal panel 60.

In some embodiments of the present application, a first gap is provided between the top of the baffle and the plane of the carrier 52 to reduce the probability of collision between the baffle and the carrier 52. When the display 1 is transported or impacted by the outside, the bearing part 52 and the baffle are extruded, and due to the first gap, the probability of collision between the bearing part 52 and the baffle when being extruded can be reduced, the probability of the baffle breaking off from the back plate side wall 14 is reduced, and the durability of the baffle is improved.

In some embodiments of the present application, a positioning portion 145 is disposed on a side of the back panel sidewall 14 away from the light guide plate 30, and the fixing portion 51 is provided with a fixing hole 511, and the single positioning portion 145 can be snapped into the single fixing hole 511, so that the glue frame 50 is snapped onto the back panel sidewall 14. The positioning parts 145 are provided with a plurality of positioning parts, and can connect the adhesive frame 50 and the stability of the clamping of the backboard side wall 14, so that the probability of falling off of the adhesive frame 50 is reduced.

The left and right sides of the second notch 152 are respectively provided with a positioning portion 145, and when the positioning portion 145 is matched with the fixing hole 511, the left and right sides of the second notch 152 are pressed by the pressing force generated by the matching of the positioning portion 145 and the fixing hole 511 to press the diaphragm 40, so that the diaphragm 40 is pressed on one side of the extension portion 121 facing the bearing portion 52, and the diaphragm 40 is fixedly connected to the back plate side wall 14.

In other embodiments, the positioning portion 145 is not disposed on the left side and the right side of the second notch 152, so that the degree of uneven stress on the diaphragm 40 and the back plate sidewall 14 in the second notch 152 caused by the pressing force generated by the positioning portion 145 and the fixing fit can be reduced, and the degree of damage to the diaphragm 40 can be reduced.

In some embodiments of the present application, the back panel sidewall 14 includes a first back panel wall 141, a second back panel wall 142 and a third back panel wall 143, the second back panel wall 142 and the third back panel wall 143 are respectively disposed at adjacent positions of two ends of the first back panel wall 141, the second back panel wall 142 and the third back panel wall 143 are disposed at the same side of the first back panel wall 141, and the display 1 includes the light bar 70 connected to the first back panel wall 141 in a direction close to the light guide panel sidewall.

The bottom plate 13 further includes a limiting post disposed adjacent to the light bar 70, and the limiting post extends toward the bearing portion 52.

The spacing post is located between first back plate wall 141 and light guide plate 30, and the spacing post includes first spacing post 133 and the second spacing post 134 of setting relatively with first spacing post 133, and first spacing post 133 is located the corner inboard that second back plate wall 142 and first back plate wall 141 formed, and the corner inboard that third back plate wall 143 and first back plate wall 141 formed is located to the second spacing post 134. The side wall of the light guide plate side wall, which is close to the light bar 70, is a first light guide plate side wall 331, the light guide plate side wall further comprises a second light guide plate side wall 332 and a third light guide plate side wall 333 connected to two ends of the first light guide plate side wall 331, the second light guide plate side wall 332 and the third light guide plate side wall 333 are located on the same side of the first light guide plate side wall 331, a stepped first light guide plate notch 341 is formed between the second light guide plate side wall 332 and the first light guide plate side wall 331, a stepped second light guide plate notch 342 is formed between the third light guide plate side wall 333 and the first light guide plate side wall 331, the first light guide plate notch 341 is limited by the first limiting post 133, the second light guide plate notch 342 is limited by the second limiting post 134, so that the light guide plate 30 is positioned between the first limiting post 133 and the second limiting post 134, the degree of random shaking of the light guide plate 30 is reduced, and the shaking amount of the light guide plate 30 is limited by the first limiting post 133 and the second limiting post 134.

It should be noted that, a gap is formed between the first light guide plate notch 341 and the first limiting post 133, and a gap is formed between the second light guide plate notch 342 and the second limiting post 134. The expansion of the light guide plate 30 occurs when the light irradiation temperature is higher for a long time, and because the gap is formed between the first light guide plate notch 341 and the first limiting post 133 and the gap is formed between the second light guide plate notch 342 and the second limiting post 134, the abrasion degree between the side wall of the light guide plate and the limiting post when the light guide plate 30 expands can be reduced, so that the light guide plate 30 can be kept complete, and the light processing capability of the light guide plate 30 is stable. Meanwhile, in the transportation process of the display 1, the light guide plate 30 may shake, and since the gap is formed between the first light guide plate notch 341 and the first limiting post 133 and the gap is formed between the second light guide plate notch 342 and the second limiting post 134, the collision degree between the light guide plate 30 and the limiting post can be reduced.

In some embodiments, the number of the limiting posts may be two or four, and when the number of the limiting posts is two, the two limiting posts are disposed on one side close to the side wall of the same back plate 10.

In some embodiments of the present application, to prevent the light guide plate 30 from being damaged by being expanded and pressed to the rear plate 10 to the right, an elastic body is provided at the inner side of the corner formed at the adjacent position of the third rear plate wall 143 and the fourth rear plate wall 144, and the inner side of the corner formed at the connection of the second rear plate wall 142 and the fourth rear plate wall 144, respectively, that is, at the corner of the end of the right side edge of the light guide plate 30, an elastic body is provided between the fourth rear plate walls 144 of the light guide plate 30 for providing a buffer for the expansion of the light guide plate 30.

In some embodiments of the present application, an included angle between the first blocking plate 12212 and a side of the first extension portion 12211 away from the light guide plate 30 is an obtuse angle, and an included angle between the second blocking plate 12222 and a side of the second extension portion 12221 away from the light guide plate 30 is an obtuse angle. In some embodiments, the angle between the first blocking plate 12212 and the side of the first extension portion 12211 away from the light guide plate 30 is the same as the angle between the second blocking plate 12222 and the side of the second extension portion 12221 away from the light guide plate 30, which is the angle α. The first baffle 12212 and the back plate sidewall 14 in the second notch 152 are connected by the first extension portion 12211, and since the first extension portion 12211 and the first baffle 12212 form an obtuse angle, the first extension portion 12211 forms a stable support for the first baffle 12212, so as to reduce the probability of breaking the first baffle 1221. Similarly, the second extension 12221 forms a stable support for the second baffle 12222, reducing the probability of breakage of the second baffle 1222, so that the membrane 40 is stably retained on the sides of the first baffle 1221 and the second baffle 1222 near the side wall of the light guide plate.
