[0002] In recent years, curved screens have attracted much attention and their market share in the display market is increasing. Not only are the bending radius getting smaller and the frame getting narrower, but even variable curvature backlight modules have emerged.

For example, joints are easily formed between the spliced ​​light panels due to the frequent alternation of flat and curved displays of the backlight module, which in turn causes uneven black lines on the backlight module, affecting the user experience.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description". Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.

[0036] See also Figure 1 The embodiment of the present application provides a backlight module, which mainly refers to a large display screen, which needs to be spliced ​​by multiple light panels, and the backlight module can be a flat screen, a curved screen, and a curved screen with variable curvature. In this embodiment, it is mainly for a curved screen with variable curvature, because this type of curved screen needs to switch repeatedly between flat display and curved display, and the switching method is generally to adjust the curvature of the back panel 1 in the length direction X. During the adjustment process, multiple spliced ​​light panels will be driven to adjust the curvature together, so that it is easier to have seams at the splicing point, resulting in the problem of black lines on the display. Specifically, the backlight module includes:

[0037] A back plate 1 having a length direction X and having a first side 11 and a second side 12 arranged opposite to each other along the length direction X;

[0038] A light board splicing module 2 is provided on the back panel 1, and the splicing direction of the light board splicing module 2 is the length direction X. Along the length direction X, the light board splicing module 2 has a first extrusion side 22 and a second extrusion side 23 that are arranged opposite to each other;

[0039] A first elastic component 3 and a second elastic component 4, wherein two ends of the first elastic component 3 are respectively connected to the first side 11 and the first extrusion side 22, and two ends of the second elastic component 4 are respectively connected to the second side 12 and the second extrusion side 23, and the first elastic component 3 and the second elastic component 4 jointly form extrusion on the light board splicing module 2 in the length direction X.

[0040] The technical solution provided by the present application is mainly to arrange elastic components connected to the back panel 1 on both sides of the length direction X of the light board splicing module 2, and use the elastic components to squeeze the light board splicing module 2, so as to effectively improve the problem of the splicing seam of the light board splicing module 2, which causes the black line of the backlight module. In detail, by arranging the first elastic component 3 between the first side 11 and the first squeezing side 22, and arranging the second elastic component 4 between the second side 12 and the second squeezing side 23, the first elastic component 3 and the second elastic component 4 are located in the length direction X, that is, in the splicing direction of the light board splicing module 2, so that the first elastic component 3 and the second elastic component 4 can respectively apply an elastic force to the light board splicing module 2, and the elastic forces applied by the first elastic component 3 and the second elastic component 4 are both in the length direction X and the elastic force applied by the first elastic component 3 to the light board splicing module 2 is opposite to the elastic force applied by the second elastic component 4 to the light board splicing module 2, so as to form a squeezing force on the light board splicing module 2, which is conducive to making the splicing of the light board splicing module 2 more compact and reducing the appearance of splicing seams. Furthermore, when the backlight module switches between flat display and curved display, the squeezing force still exists, thereby effectively improving the problem of increased seams caused by frequent switching of the backlight module between flat display and curved display.

[0041] It should be noted that when the curvature of the backlight module is adjusted, based on the current technology, the part of the backlight module in the length direction X is generally bent and adjusted, that is, the bending adjustment is performed in the length direction X of the back panel 1. All embodiments of the present application are mainly for the backlight module spliced ​​in the length direction X of the back panel 1, but for the backlight module spliced ​​in the width direction Y of the back panel 1, the technical solution provided in the present application is still applicable.

[0042] In some embodiments, see Figure 1The first side 11 of the back plate 1 and the second side 12 of the back plate 1 are respectively provided with a first flange 13 and a second flange 14. The first flange 13 and the second flange 14 are mainly used to limit the light board 21 within the range of the back plate 1, and also to limit, protect and shield other components and wires so that other components and wires are located inside the back plate 1. The first extrusion side 22 and the first flange 13 are arranged in alignment and spaced apart to define a first extrusion area 131, the first elastic component 3 is arranged in the first extrusion area 131 and the two ends of the first elastic component 3 are respectively connected to the first flange 13 and the first extrusion side 22, and the elastic characteristics of the first elastic component 3 are utilized to give the first extrusion side 22 an extrusion force toward the second extrusion side 23; the second extrusion side 23 and the second flange 14 are arranged in alignment and spaced apart to define a second extrusion area 141, the second elastic component 4 is arranged in the second extrusion area 141 and the two ends of the second elastic component 4 are respectively connected to the second flange 14 and the second extrusion side 23, and the elastic characteristics of the second elastic component 4 are utilized to give the second extrusion side 23 an extrusion force toward the first extrusion side 22, so that the multiple light boards 21 used for splicing in the light board splicing module 2 have areas that move toward each other and are squeezed to reduce the splicing seams. To ensure that the first elastic component 3 and the second elastic component 4 can always squeeze the light board splicing module 2, in this embodiment, the length of the first squeezing area 131 in the length direction X is set to be smaller than the length of the first elastic component 3 in the length direction X, and the length of the second squeezing area 141 in the length direction X is set to be smaller than the length of the second elastic component 4 in the length direction X. In addition, when the backlight module is adjusted in curvature, that is, when the light board 21 is bent along with the backboard 1, the first elastic component 3 and the second elastic component 4 can still play a squeezing role, effectively preventing the splicing seam from becoming larger due to the curvature adjustment.

[0043] For further information, see Figure 1 and Figure 4The first elastic component 3 includes a plurality of first elastic members 31, and the second elastic component 4 includes a plurality of second elastic members 41. The plurality of first elastic members 31 are arranged in the first extrusion area 131, and the plurality of second elastic members 41 are arranged in the second extrusion area 141. The first extrusion area 131 and the second extrusion area 141 both extend along the width direction Y, and the first extrusion area 131 and the second extrusion area 141 are arranged opposite to each other along the length direction X. The two ends of the first elastic member 31 are respectively connected to the first flange 13 and the first extrusion side 22, and the first elastic member 31 is in a compressed state, so that the first elastic member 31 can apply an extrusion force toward the second extrusion side 23 to the first extrusion side 22; the two ends of the second elastic member 41 are respectively connected to the second flange 14 and the second extrusion side 23, and the second elastic member 41 is in a compressed state, so that the second elastic member 41 can apply an extrusion force toward the first extrusion side 22 to the second extrusion side 23. Through the extrusion forces in two opposite directions and both toward the splicing direction (length direction X), the splicing seam of the light board splicing module 2 is reduced.

[0044] It should be noted that, in this embodiment, the first elastic member 31 and the second elastic member 41 are both springs, and the springs are always in a compressed state to maintain a continuous squeezing effect on the light board splicing module 2. In other embodiments, the elastic member may also be made of other elastic materials, such as elastic rubber, air cushions, etc.

[0045] Furthermore, the back panel 1 has a width direction Y, and the width direction Y intersects with the length direction X. In the present embodiment, the orthographic projection of the backlight module is rectangular, and correspondingly, the orthographic projections of the back panel 1 and the light board splicing module 2 are both rectangular, and the intersection of the length direction X and the width direction Y is specifically a vertical intersection. A plurality of first elastic members 31 are arranged at intervals along the width direction Y, and a plurality of second elastic members 41 are arranged at intervals along the width direction Y. Preferably, the plurality of first elastic members 31 are arranged at equal intervals, and the plurality of second elastic members 41 are also arranged at equal intervals, and each first elastic member 31 is arranged in opposition to a second elastic member 41, which is beneficial to maintaining the force balance of the light board splicing module 2 and avoiding the light board splicing module 2 from being offset when the curvature changes.

[0046] In some embodiments, the back panel 1 has a width direction Y, and the width direction Y intersects with the length direction X. In this embodiment, the orthographic projection of the backlight module is rectangular, and correspondingly, the orthographic projections of the back panel 1 and the light panel splicing module 2 are both rectangular, and the intersection of the length direction X and the width direction Y is specifically a vertical intersection. Figure 1 and Figure 2, the back panel 1 is provided with a first pressure strip 5 and a second pressure strip 6 which are arranged oppositely on both sides along the width direction Y. The first pressure strip 5 and the second pressure strip 6 are respectively pressed on both sides of the light panel splicing module 2 along the width direction Y and connected to the back panel 1. By using the first pressure strip 5 and the second pressure strip 6 to press the light panel splicing module 2 on both sides of the width direction Y, when the backlight module changes its curvature, the light panel splicing module 2 changes its curvature synchronously and can still be as close to the back panel 1 as possible, so as to avoid the light panel splicing module 2 and the back panel 1 being partially separated and arched. It should be noted that the secondary function of the first pressure strip 5 and the second pressure strip 6 is to play an auxiliary fixing role, that is, to assist the light panel splicing module 2 in being fixed to the back panel 1. The main function is to ensure that the light panel splicing module 2 can be close to the back panel 1 as much as possible, so as to avoid the light panel splicing module 2 and the back panel 1 from being debonded or partially arched. In other words, for the main fixation of the light panel splicing module 2 and the back panel 1, screw locking and / or gluing are still required. Preferably, the first pressure strip 5 and the second pressure strip 6 both extend along the length direction X, so that the first pressure strip 5 and the second pressure strip 6 cover the length of the light board splicing module 2 in the length direction X as much as possible, thereby ensuring to the greatest extent that the pressure strip can play a role in closely fitting the back panel 1 over the entire length section of the light board splicing module 2.

[0047] Furthermore, the length of the first bead 5 along the length direction X and the length of the second bead 6 along the length direction X are not less than the length of the light board splicing module 2 along the length direction X. In this embodiment, the length of the first bead 5 and the length of the second bead 6 are equal and equal to the length of the light board splicing module 2 in the length direction X, that is, the first bead 5 and the second bead 6 can just cover both sides of the light board splicing module 2 in the width direction Y, thereby playing a role in preventing arching and debonding.

[0048] In some embodiments, see Figures 1 to 3 as well as Figure 5 and Figure 6The back panel 1 is provided with a plurality of first snap-in grooves 15 and a plurality of second snap-in grooves 16, which are respectively arranged on both sides of the back panel 1 along the width direction Y, and the plurality of first snap-in grooves 15 and the plurality of second snap-in grooves 16 are arranged at intervals along the length direction X. The first pressure strip 5 is provided with a plurality of first snap-in members 51 on the side facing the back panel 1, and the second pressure strip 6 is provided with a plurality of second snap-in members 61 on the side facing the back panel 1. The first snap-in members 51 are arranged in alignment with the first snap-in grooves 15 and snap-connected, and the second snap-in members 61 are arranged in alignment with the second snap-in grooves 16 and snap-connected. The pressure strip is connected to the back panel 1 by snap-in, which is convenient for disassembly. It should be noted that the first pressure strip 5 and the second pressure strip 6 are partially pressed on the light board splicing module 2 and partially pressed on the back panel 1, and the side facing away from the back panel 1 is parallel to the surface of the light board splicing module 2. Such a setting is conducive to the pressure strip on the light board splicing module 2 to be flat and avoid uneven force. From the above-mentioned pressing method, it can be seen that the part of the first pressure strip 5 pressed on the light board splicing module 2 and the part pressed on the back panel 1 have a thickness difference, and the thickness difference is equal to the thickness of the light board splicing module 2. Similarly, the second pressure strip 6 has the same structure as the first pressure strip 5 and will not be repeated.

[0049] In some embodiments, see Figure 7 and Figure 8 The first flange 13 is provided with two first positioning holes 132 spaced apart along the width direction Y, and the second flange 14 is provided with two second positioning holes 142 spaced apart along the width direction Y. Among them, one first positioning hole 132 is arranged in alignment with one second positioning hole 142, and first positioning protrusions 52 are arranged on both sides of the first pressure strip 5 along the length direction X. The two first positioning protrusions 52 are respectively connected with a group of first positioning holes 132 and second positioning holes 142 arranged in alignment, and the two second positioning protrusions 62 are respectively connected with another group of first positioning holes 132 and second positioning holes 142 arranged in alignment. The arrangement of the positioning holes and the positioning protrusions is conducive to pre-positioning the pressure strip during assembly, facilitating the alignment assembly of the pressure strip, and avoiding the troublesome assembly caused by a large number of buckle grooves.

[0050] It should be noted that, in any of the above embodiments, the light board splicing module 2 includes a plurality of light boards 21. The plurality of light boards 21 are spliced ​​in sequence along the length direction X of the back panel 1, and the two light boards 21 located at the beginning and the end of the splicing are respectively located at the first extrusion side 22 and the second extrusion side 23 on the two sides away from each other in the length direction X, so as to avoid the elastic component being arranged on the side of the light board 21 between the beginning and the end, which may affect the normal display of the picture. In other words, the number of light boards 21 spliced ​​along the length direction X has nothing to do with the number of elastic components. No matter how many light boards 21 there are, only two elastic components need to be arranged, and the two elastic components are respectively located on both sides of the light board splicing module 2 in the length direction X, so as to adapt to a variety of backlight modules of different specifications.

[0051] The embodiment of the present application also provides a display device, which includes a backlight module as described in any of the above embodiments. Because the display device includes the backlight module described in the above embodiments, it also has the structure and beneficial effects of the backlight module. The derivation process of the specific structure and beneficial effects can be found in the above embodiments, which will not be repeated here.

[0052] The basic concepts have been described above.

Although not explicitly stated herein, those skilled in the art may make various modifications, improvements and amendments to the present application.
