[0002] The present disclosure claims priority to Chinese patent application number 202311190262.4 filed on September 14, 2023, entitled “Display device”, priority to Chinese patent application number 202311419213.3 filed on October 30, 2023, entitled “Display device”, and priority to Chinese patent application number 202311430743.8 filed on October 30, 2023, entitled “Display device”, the contents of which are all incorporated into the present disclosure. Technical Field

[0003] The present disclosure relates to the technical field of display devices, and in particular to a display apparatus. Background Art

[0004] Generally, backlights for liquid crystal displays are classified into edge-type and direct-type backlights based on the location of the light source. Edge-type backlights have light sources located on one or both sides of a light guide plate and are structured to irradiate light into the light guide plate. Direct-type backlights have a structure in which the light source is positioned below a diffuser plate to irradiate light over the entire diffuser plate.

[0005] Recently, light emitting diodes (LEDs) have been widely used as light sources. In the case of a direct-lit backlight device, a plurality of LEDs are arranged at predetermined intervals on the upper surface of a printed circuit board. An LED lens is mounted on the upper side of the plurality of LEDs to diffuse the light emitted from the LEDs.

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] 1 , 2 , 4 , 5 and 7 , some embodiments of the present disclosure provide a display device including a display panel and a backlight module, wherein the display panel is configured to display an image.

[0025] In some embodiments, the backlight module is arranged on the non-display surface of the display panel, and the backlight module includes a connector 20 and multiple light strips 1. The light strips 1 have multiple light-emitting elements 10 arranged in sequence along a first direction, wherein the first direction is the extension direction of the light strips 1.

[0026] In one embodiment, the plurality of light bars 1 include a first light bar 11 and a second light bar 12 , and the connector 20 is disposed between the first light bar 11 and the second light bar 12 , that is, the first light bar 11 and the second light bar 12 are distributed on both sides of the connector 20 .

[0027] In one embodiment, the first light bar 11 , the connector 20 , and the second light bar 12 are arranged from left to right.

[0028] In one embodiment, the first light bar 11 , the connector 20 , and the second light bar 12 are arranged from right to left.

[0029] In one embodiment, the first light bar 11 , the connector 20 , and the second light bar 12 are arranged from the sky side to the ground side.

[0030] In one embodiment, the first light bar 11 , the connector 20 , and the second light bar 12 are arranged from the ground side to the sky side.

[0031] The present disclosure introduces the first light bar 11, the connector 20, and the second light bar 12 in a manner of being arranged from left to right, and other manners are not described in detail. However, those skilled in the art should note that several other exemplary arrangements can be obtained based on the present disclosure without creative work.

[0032] In one embodiment, a first plug-in fitting structure 30 is provided between the first light bar 11 and the connector 20 , so as to achieve plug-in electrical connection between the first light bar 11 and the connector 20 through the first plug-in fitting structure 30 .

[0033] In one embodiment, a second plug-in fitting structure 31 is provided between the second light bar 12 and the connector 20 , so as to achieve plug-in electrical connection between the second light bar 12 and the connector 20 through the second plug-in fitting structure 31 .

[0034] The first plug-in mating structure 30 and the second plug-in mating structure 31 are located on both sides of the connector 20, and at least one of the first plug-in mating structure 30 and the second plug-in mating structure 31 is staggered relative to the extension direction of the light strip 1. In other words, at least one of the first plug-in mating structure 30 and the second plug-in mating structure 31 is not aligned with the extension direction of the light strip 1.

[0035] That is to say, one of the first plug-in mating structure 30 and the second plug-in mating structure 31 may not be located on the same straight line as the extension direction of the light strip 1, while the other is normally plugged in with the connector 20, that is, the other is located on the same straight line as the extension direction of the light strip 1.

[0036] In one embodiment, neither the first plug-in mating structure 30 nor the second plug-in mating structure 31 is located in a straight line with the extension direction of the light bar 1. In other words, the first plug-in mating structure 30 disposed between the first light bar 11 and the connector 20 is not located in a straight line with the extension direction of the light bar 1, and the second plug-in mating structure 31 disposed between the second light bar 12 and the connector 20 is also not located in a straight line with the extension direction of the light bar 1.

[0037] In one embodiment, the light strip 1 is configured as a long strip structure, and a plurality of light-emitting elements 10 are arranged in sequence along a first direction of the light strip 1. The left and right directions shown in FIG1 are the first directions of the light strip 1, that is, the extension direction of the light strip 1. The plurality of light-emitting elements 10 on the same light strip 1 are arranged in sequence along the same straight line.

[0038] In one embodiment, the spacing between two adjacent light-emitting elements 10 is set based on factors such as the number of partitions required for the backlight module. When the spacing between two adjacent light-emitting elements 10 on the light bar 1 is small, if the connector 20 and the light bars 1 on both sides still use the existing plug-in mating structure, the spacing between the two light-emitting elements 10 on both sides of the connector is large due to the presence of the plug-in mating structure, which cannot meet the requirement of reducing the spacing between two adjacent light-emitting elements 10. When the smaller spacing requirement is met, there is a problem that the plug-in mating structure cannot be placed properly, or the plug-in mating structure is too close to the light-emitting element 10, causing problems such as subjective light shadows on the display device.

[0039] The present disclosure provides a display device, which is arranged by staggering at least one of the first plug-in mating structure 30 and the second plug-in mating structure 31 with respect to the extension direction of the light bar 1, that is, at least one of the first plug-in mating structure 30 and the second plug-in mating structure 31 is not located on the same straight line with the extension direction of the light bar 1, so that the distance between the first light bar 11 and the second light bar 12 on both sides connected by the connector 20 along the extension direction of the light bar 1 is not limited by the size of the first plug-in mating structure 30 and the second plug-in mating structure 31 after plugging, thereby avoiding occupying too much space between the first light bar 11 and the second light bar 12 on both sides connected by the connector 20 after plugging. In this way, when the spacing between the light-emitting elements 10 on the light bar 1 becomes smaller, it is also ensured that the first plug-in mating structure 30 and the second plug-in mating structure 31 can be placed apart, and it is avoided that the first plug-in mating structure 30 and the second plug-in mating structure 31 are too close to the light-emitting elements 10, causing problems such as subjective light shadows of the display device, thereby ensuring the display effect of the display device.

[0040] In one embodiment, the number of the first light bar 11 and the second light bar 12 are both plural, and are respectively arranged on the left and right sides of the connector 20 in pairs. That is, the plurality of first light bars 11 are arranged on one side of the connector 20, and the plurality of second light bars 12 are arranged on the other side of the connector 20, and the first light bars 11 and the second light bars 12 on the same side are arranged in sequence along the length direction of the connector 20 (the up and down direction as shown in Figure 1).

[0041] In one embodiment, the first plug-in mating structure 30 includes a first plug-in portion 301 and a second plug-in portion 302 that cooperate with each other. The first plug-in portion 301 is disposed on the first light bar 11 , and the second plug-in portion 302 is disposed on the connector 20 .

[0042] In one embodiment, the second plug-fitting structure 31 includes a third plug-fitting portion 311 and a fourth plug-fitting portion 312 . The first plug-fitting portion 311 is disposed on the second light bar 12 , and the second plug-fitting portion 312 is disposed on the connector 20 .

[0043] In one embodiment, as shown in Figure 1 , the first plug-in mating structure and the second plug-in mating structure are aligned along the same straight line along the extension direction of the light bar. This arrangement allows the spacing between the LEDs on either side of the connector to exceed the size limitations of the original plug-in mating structure and connector, further reducing the spacing between the LEDs on either side of the connector.

[0044] In one embodiment, a first bending portion 15 is provided on the first light bar 11, and a fourth bending portion 19 is provided on the second light bar 12. The first bending portion 15 is perpendicular to the extension direction of the first light bar 11, the first plug-in portion 301 is provided on the first bending portion 15, the fourth bending portion 19 is perpendicular to the extension direction of the second light bar 12, and the second plug-in portion 302 is provided on the fourth bending portion 19. Such an arrangement can enable the first plug-in portion 301 on the first bending portion 15 to be staggered with the extension direction of the light bar 1, and the second plug-in portion 302 on the fourth bending portion 19 to be staggered with the extension direction of the second light bar 12.

[0045] In one embodiment, a first bending portion 15 and a fourth bending portion 19 are provided on the first light bar 11 and the second light bar 12, a first plug-in portion 301 is provided on the first bending portion 15, and a second plug-in portion 302 is provided on the fourth bending portion 19. The second plug-in portions 302 located on both sides of the connector 20 are arranged opposite to each other. As shown in Figure 8, the second plug-in portions 302 located on both sides of the connector 20 are arranged opposite to each other.

[0046] With this arrangement, the second plug-in portions 302 on the connector 20 are arranged in the same or similar manner as the existing arrangement, without requiring major changes to the connector 20 , thereby simplifying the manufacturing process.

[0047] The second plug-in portions 302 on both sides of the connector 20 are arranged opposite to each other in pairs, so that the multiple second plug-in portions 302 are arranged more densely along the length direction of the connector 20 (the up and down direction as shown in Figure 8), thereby reducing the spacing width between the two light strips 1 on the same side, making the arrangement of the multiple light strips 1 on the same side more dense, meeting the demand for increasing the number of partitions of the backlight module.

[0048] In one embodiment, the first bend portion 15 on the first light bar 11 and the fourth bend portion 19 on the second light bar 12 are extended along an extension direction perpendicular to the light bar 1. Figure 1 is an implementation scheme provided by the present disclosure. In this way, the first light bar 11 and the second light bar 12 are both formed into an L shape.

[0049] In one embodiment, a first plug-in portion 301 is provided at the first end of the first bending portion 15, and a second plug-in portion 302 is provided at the first end of the connector 20. The first plug-in portion 301 and the second plug-in portion 302 are plug-fitted along an extension direction parallel to the light strip 1. The first plug-in portion 301 on the first light strip 11 and the second plug-in portion 302 on the connector 20 together form a first plug-fitting structure 30.

[0050] In one embodiment, a fourth bending portion 19 is provided on the second light strip 12, a third plug-in portion 311 is provided at the first end of the fourth bending portion 19, and a fourth plug-in portion 312 is provided at the second end of the connector 20. The third plug-in portion 311 and the fourth plug-in portion 312 are plug-fitted to form a second plug-fitting structure 31 to realize electrical connection between the second light strip and the connector 20.

[0051] By providing a first bending portion 15 at the first end of the first light strip 11, the first bending portion 15 extends perpendicular to the extension direction of the light strip 1, and a first plug-in portion 301 for plugging with the connector 20 is provided on the first bending portion 15, so that the first plug-in portion 301 is staggered with the extension direction of the light strip 1.

[0052] A fourth bend 19 is provided at the end of the second light bar 12, extending perpendicularly to the light bar. A third plug-in portion 311 is provided on the fourth bend 19, and a fourth plug-in portion 312 is provided on the connector 20. The third plug-in portion 311 cooperates with the fourth plug-in portion 312 to achieve an electrical connection between the light bar and the connector 20. By extending the third plug-in portion 311 perpendicularly to the light bar, the third plug-in portion 311 is not aligned with the light bar in the same straight line, thereby achieving a staggered arrangement of the third plug-in portion 311 and the light bar 1 in its extension direction.

[0053] 2 , a first bending portion 15 is provided at the first end of the first light bar 11. The first bending portion 15 extends in a direction perpendicular to the connector 20, and a first plug-in portion 301 is provided on the first bending portion 15. Thus, the first plug-in portion 301 for connecting to the connector 20 and the first light bar 11 are not provided on the same straight line.

[0054] Since the first plug-in portion 301 and the first light bar 11 are not arranged on the same straight line, compared to the case where the first plug-in portion 301 and the first light bar 11 are arranged on the same straight line, the distance between the LEDs on both sides of the connector 20 caused by the size of the first plug-in portion 301 can be reduced, thereby breaking the current situation where the size of the LEDs cannot be further reduced.

[0055] 2 , a fourth bending portion 19 is provided at the first end of the second light strip 12, and the fourth bending portion 19 extends in a direction perpendicular to the connector 20, and a third plug-in portion 311 is provided on the fourth bending portion 19, thereby making the third plug-in portion 311 for connecting to the connector 20 and the second light strip 12 not arranged on the same straight line.

[0056] In one embodiment, as shown in Figure 2, the first end of the connector 20 is provided with a second plug-in portion 302 for connecting to the first plug-in portion 301, and the second end of the connector 20 is provided with a fourth plug-in portion 312 for connecting to the third plug-in portion 311. The connection between the first light bar 11 and the connector 20 and the connection between the second light bar 12 and the connector 20 are realized by connecting the second plug-in portion 302 to the first plug-in portion 301 and the third plug-in portion 311 to the fourth plug-in portion 312.

[0057] In one embodiment, as shown in FIG. 2 , the first plug-in mating structure 30 and the second plug-in mating structure 31 are not on the same straight line in the extension direction of the first light bar 11. Compared with the case where the first plug-in mating structure 30 and the second plug-in mating structure 31 are on the same straight line in the extension direction of the first light bar 11, the distance between the LEDs on both sides of the connector 20 can be further reduced, thereby better solving the problem that the existing LED spacing cannot be further reduced.

[0058] To put it another way, this arrangement allows the second plug-in portions 302 on either side of the connector 20 to overlap along the width of the connector 20 (i.e., the left-right direction in FIG. 2 ). The structure of the connector 20 can be illustrated with reference to FIG. 9 . The second plug-in portions 302 on either side of the connector 20 are staggered in pairs along the extension direction of the first light bar 11. This reduces the left-right dimension of the connector 20 and prevents the connector 20 from occupying excessive space between the first and second light bars 11, 12 on either side of the connector 20, thereby ensuring a good display effect for the display device.

[0059] 3 , which is a schematic diagram of cutting a light bar 1 provided by the present disclosure.

[0060] The first bending portions 1515 of the first light bar 11 and the second light bar 12 extend in the same direction, which facilitates cutting and fully utilizes the light board material, thereby reducing material waste and lowering production costs.

[0061] In one embodiment, the first bending portion 1515 of the first light bar 11 and the fourth bending portion 19 of the second light bar 12 extend in different directions, as shown in FIG. 2 . The present disclosure does not limit this, as long as the first bending portion 1515 can be staggered in the extension direction of the light bar 1 .

[0062] In one embodiment, the light-emitting element 10 is arranged near the edge end of the first light bar 11 or the second light bar 12 along the extension direction of the light bar 1, that is, near the end in the left and right directions in Figure 3, so as to reduce the distance between the light-emitting element 10 located at the end and the connector 20.

[0063] Such a configuration can further reduce the distance between two adjacent light-emitting elements 10 close to the connector 20 on the first light bar 11 or the second light bar 12 on both sides connected to the connector 20, thereby avoiding the excessive spacing between the light-emitting elements 10 caused by the ends of the first light bar 11 or the second light bar 12 occupying too much space between the first light bar 11 or the second light bar 12 on both sides of the connector 20.

[0064] In one embodiment, one of the first light bar 11 and the second light bar 12 located on both sides of the connector 20 is provided with a first bending portion 1515 at an extended position of the end thereof according to the design requirements of the actual light emitting element 10 .

[0065] In one embodiment, the first light bar 11 and the second light bar 12 located on both sides of the connector 20 are both provided with a first bending portion 15 extending from their ends, and a first plugging portion 301 is provided on the side of the first bending portion 15 .

[0066] That is, in one embodiment, the first plug-in portion 301 of at least one of the first light bar 11 or the second light bar 12 is not located in a straight line with the extension direction of the light bar 1. In other words, at least one of the first plug-in mating structure 30 and the second plug-in mating structure 31 is not located in a straight line with the extension direction of the light bar 1, so long as the encryption requirements of the light-emitting element 10 are met.

[0067] In one embodiment, the second plug-in portions 302 located on both sides of the connector 20 are arranged relative to or staggered according to actual usage requirements. As long as the extension directions of the first light bar 11 and the second light bar 12 located on both sides of the connector 20 can be located on the same straight line and the multiple light-emitting elements 10 are evenly spaced, it is sufficient to ensure that multiple partitions of the backlight module have a uniform brightness lighting effect.

[0068] In one embodiment, the first plug-in portion 301 is the first between the plug and the socket, and the second plug-in portion 302 is the second between the plug and the socket. The first plug-in portion 301 is inserted into or pulled out of the second plug-in portion 302 along an extension direction parallel to the light strip 1.

[0069] In one embodiment, the first plug-in portion 301 and the second plug-in portion 302 are other plug-in structures, as long as the electrical connection between the first plug-in portion 301 and the second plug-in portion 302 can be achieved, and this disclosure does not limit this.

[0070] In one embodiment, referring to Figures 4 and 5, the multiple light strips 1 further include a third light strip 13 and a fourth light strip 14. The third light strip 13 and the first light strip 11 are located on the same side of the connector 20 and are arranged parallel to each other. The first end of the third light strip 13 and the first end of the first light strip 11 are connected by a second bending portion 16, and the second bending portion 16 is perpendicular to the extension direction of the light strip 1.

[0071] The fourth light bar 14 and the second light bar 12 are located on the same side of the connector 20 and are arranged parallel to each other. The first end of the fourth light bar 14 and the first end of the second light bar 12 are connected by a third bending portion 17, and the third bending portion 17 is perpendicular to the extension direction of the light bar 1.

[0072] A first plug-in fitting structure 30 is provided between the second bending portion 16 and the connector 20 , and a second plug-in fitting structure 31 is provided between the third bending portion 17 and the connector 20 .

[0073] With such a configuration, the spacing between the light strips 1 on both sides connected to the connector 20 along the extension direction of the light strips 1 is not limited by the size of the first plug-in mating structure 30 and the second plug-in mating structure 31 after being plugged in, thereby avoiding occupying too much space between the light strips 1 connected on both sides of the connector 20 after being plugged in, thereby ensuring the luminous effect of the display device; at the same time, the size of the connector 20 located between the light strips 1 on both sides is specially set according to user needs to ensure that when the density of the light-emitting elements 10 in the backlight module is increased, the connector 20 will not occupy too much space between the light strips 1 on both sides, thereby ensuring the luminous effect of the display device.

[0074] In one embodiment, a first plug-in portion 301 is provided on a side of the second bending portion 16 close to the connector 20, and a second plug-in portion 302 is provided on the connector 20. The first plug-in portion 301 and the second plug-in portion 302 on the second bending portion 16 are plug-fitted along an extension direction parallel to the light bar 1, and together form a first plug-fitting structure 30. The first plug-in portion 301 and the second plug-fitting portion 302 on the third bending portion 17 are plug-fitted along an extension direction parallel to the light bar 1, and together form a second plug-fitting structure 31.

[0075] In one embodiment, the first plug-in mating structure 30 and the second plug-in mating structure 31 are located on the same straight line along the extension direction of the first light strip 11, but are not on the same straight line as the extension of the light strip. This arrangement ensures that the distance between the LED at the first end of the first light strip 11 and the connector 20 will not be unable to be reduced due to the presence of the first plug-in mating structure.

[0076] In one embodiment, the first plug-in mating structure 30 and the second plug-in mating structure 31 are not located on the same straight line along the extension direction of the first light bar 11, and are not on the same straight line as the extension of the light bar. As a result, in the length direction of the connector 20, the first plug-in mating structure 30 and the second plug-in mating structure 31 can have overlapping parts, further reducing the distance between the LEDs on both sides of the connector 20.

[0077] 4 , in some embodiments, the second plug-in portions 302 on both sides of the connector 20 are arranged opposite to each other. The structure of the connector 20 is shown in FIG8 .

[0078] With such a configuration, the second plug-in portions 302 on the connector 20 can be arranged in a manner that is the same as or similar to the existing arrangement, thereby eliminating the need for major modifications to the connector 20 .

[0079] In addition, the second plug-in portions 302 and the fourth plug-in portions 312 on both sides of the connector 20 are arranged opposite to each other, so that the multiple second plug-in portions 302 are arranged more densely along the length direction of the connector 20, thereby reducing the spacing width between the light strips 1 on the same side, making the arrangement of the multiple light strips 1 on the same side more dense, thereby meeting the demand for increasing the number of partitions of the backlight module.

[0080] 5 , in some other embodiments, the second plug-in portions 302 and the fourth plug-in portions 312 on either side of the connector 20 are staggered, i.e., the second plug-in portions 302 and the fourth plug-in portions 312 are staggered along the length of the connector 20 (i.e., the vertical direction in FIG. 5 ). The structure of the connector 20 is shown in FIG. 9 .

[0081] Such a setting can enable the second plug-in parts 302 located on both sides of the connector 20 to be overlapped along the width direction of the connector 20 (i.e., the left and right direction in Figure 5), which can reduce the size of the connector 20 along the left and right direction, so that the connector 20 will not occupy too much space between the light strips 1 on both sides of the connector 20, thereby ensuring the display effect of the display device.

[0082] Figure 6 shows a schematic diagram of a light bar cutout according to an embodiment of the present disclosure. The third light bar 13 is connected to the first light bar 11 via a second bend 16, while the fourth light bar 14 is connected to the second light bar 12 via a third bend 17. This fully utilizes the sheet material during cutting, minimizing waste and lowering production costs.

[0083] In one embodiment, the light-emitting elements 10 are disposed near the edge ends of the light bar 1 along the extension direction of the light bar 1, that is, near the ends in the left-right direction in FIG6 , so as to reduce the distance between the light-emitting elements 10 at the ends of the light bar 1 and the connector 20. This arrangement can reduce the distance between two adjacent light-emitting elements 10 near the connector 20 on the light bars 1 on both sides connected to the connector 20, thereby avoiding excessive spacing between the light-emitting elements 10 due to the ends of the light bar 1 occupying too much space between the light bars 1 on both sides of the connector 20.

[0084] In one embodiment, the first plug-in portion 301 is one between a plug and a socket, and the second plug-in portion 302 is the other between the plug and the socket. The first plug-in portion 301 is inserted into or pulled out of the second plug-in portion 302 along an extension direction parallel to the light bar 1.

[0085] Of course, it should be noted that the first plug-in portion 301 and the second plug-in portion 302 may also be other plug-in structures, as long as the electrical connection between the first plug-in portion 301 and the second plug-in portion 302 can be achieved, and this disclosure does not limit this.

[0086] 7 , in some further embodiments, the first plug-in mating structure 30 includes a first plug-in portion 301 and a second plug-in portion 302 that fit together.

[0087] The second plug-fitting structure 31 includes a third plug-fitting portion 311 and a fourth plug-fitting portion 312 that fit together.

[0088] Among them, at least one side of the connector 20 is provided with an extension portion 21 extending perpendicularly to the first end and the second end of the connector 20, the second plug-in portion 302 is provided on the side of the extension portion 21, and at least one of the first light bar 11 and the second light bar 12 is provided with a first plug-in portion 301 on the side of one end along the extension direction of the light bar 1.

[0089] A first plug-in fitting structure 30 is provided between the first plug-in portion 301 of the first light bar 11 and the connector 20, and a second plug-in fitting structure 31 is provided between the first plug-in portion 301 of the second light bar 12 and the connector 20, wherein at least one of the first plug-in fitting structure 30 and the second plug-in fitting structure 31 is not located on the same straight line as the extension direction of the light bar 1.

[0090] The structure of the connector 20 is shown in FIG10 . At least one side of the connector 20 is provided with an extension portion 21 extending perpendicularly to the side of the connector 20 . A second plug portion 302 for plugging and connecting with the light bar 1 is provided on the side of the extension portion 21 .

[0091] In one embodiment, referring to FIG. 7 and FIG. 10 , both sides of the connector 20 are provided with extension portions 21 extending perpendicularly to the side surfaces of the connector 20 , and the second plugging portions 302 on both sides of the connector 20 are arranged opposite to each other.

[0092] Continuing with reference to Figures 7 and 10, the light strips 1 located on both sides of the connector 20 are provided with a first plug-in portion 301 on the side of one end portion along the extension direction of the light strip 1. The first plug-in portion 301 and the second plug-in portion 302 of the first light strip 11 are plug-fitted along the extension direction perpendicular to the light strip 1 to jointly form a first plug-fitting structure 30. The third plug-in portion 311 and the fourth plug-in portion 312 of the second light strip 12 are plug-fitted along the extension direction perpendicular to the light strip 1 to jointly form a second plug-fitting structure 31.

[0093] In one embodiment, the extension portions 21 on both sides of the connector 20 are staggered with respect to the extension direction of the light bar 1 , and the second plug-in portion 302 on the extension portion 21 is plugged into and matched with the first plug-in portion 301 on the light bar 1 to achieve installation of the light bar 1 .

[0094] In one embodiment, the light-emitting elements 10 are positioned near the edge of the light bar 1 along its extension direction, with a reserved location for the first plug-in portion 301. The size of the connector 20 between the light bars 1 on either side is reduced based on user needs to ensure that when the density of the light-emitting elements 10 is increased, the connector 20 does not occupy too much space between the light bars 1 on either side of the connector 20, further ensuring the display quality of the display device.

[0095] Such a configuration ensures that the spacing between the light strips 1 on both sides connected to the connector 20 along the extension direction of the light strips 1 is not limited by the size of the first plug-in mating structure 30 and the second plug-in mating structure 31 after being plugged in, thereby avoiding occupying too much space between the light strips 1 on both sides connected to the connector 20 after being plugged in, thereby ensuring the lighting effect of the display device; at the same time, the size of the connector 20 located between the light strips 1 on both sides can also be specially set according to user needs to ensure that when the density of the light-emitting elements 10 in the backlight module is increased, the connector 20 will not occupy too much space between the light strips 1 on both sides, thereby ensuring the display effect of the display device.

[0096] In one embodiment, referring to Figures 7 and 10, the extension portion 21 is arranged on the side of the connector 20 along the length direction (i.e., the left and right direction in Figure 10), that is, the extension portion 21 is arranged on the left and right sides of the connector 20, and extends along a direction perpendicular to the length direction of the connector 20 (i.e., along the left and right direction in Figure 10).

[0097] Continuing with Figures 7 and 10 , multiple extensions 21 on the same side are spaced apart along the length of the connector 20 (i.e., the vertical direction in Figure 10 ), with a gap formed between adjacent extensions 21 for inserting the end of the light bar 1. The end of the light bar 1, where the first plug-in portion 301 is located, can be inserted into the gap, thereby reducing the spacing between the light bars 1 on the left and right sides of the connector 20 and ensuring the display quality of the display device.

[0098] In one embodiment, the first plug-in portion 301 is one of a plug and a socket, and the second plug-in portion 302 is the other of the plug and the socket. The first plug-in portion 301 can be inserted into or removed from the second plug-in portion 302 along a direction parallel to the extension of the light bar 1. Of course, it should be noted that the first plug-in portion 301 and the second plug-in portion 302 can also be other plug-in structures, as long as they can achieve electrical connection between the first plug-in portion 301 and the second plug-in portion 302, and this disclosure is not limited to this.

[0099] In one embodiment, an extension portion 21 extending perpendicularly to a side surface of the connector 20 is provided only on one side of the connector 20. A second plugging portion 302 is provided on the side of the extension portion 21. The first plugging portion 301 is provided on the side of the light bar 1 on that side in the extension direction. The third plugging portion 311 of the light bar 1 on the other side is provided at one end in the extension direction of the light bar 1. This arrangement reduces the spacing between the light bars 1 on both sides of the connector 20.

[0100] It can be understood that in the above embodiment, the second plug-in portion 302 and the fourth plug-in portion 312 at the first end and the second end of the connector 20 are staggered in the extending direction of the first light bar.

[0101] Some embodiments of the present disclosure provide a display device including a display panel and a backlight module, wherein the display panel is configured to display an image.

[0102] The backlight module is arranged on the non-display surface of the display panel. The backlight module includes a connector 20 and a plurality of light strips 1. The light strips 1 have a plurality of light emitting elements 10 arranged in sequence along a first direction, wherein the first direction is the extension direction of the light strips 1.

[0103] The plurality of light strips 1 include at least three light strips 1 arranged in parallel. One end of the plurality of light strips 1 along the extension direction of the light strips 1 is connected by a connecting portion 18 , and the connecting portion 18 is arranged perpendicular to the extension direction of the light strips 1 .

[0104] At least one first plug portion 301 is provided on the connecting portion 18 . The first plug portion 301 and the extension directions of the light strips 1 are staggered. That is, the first plug portion 301 is not located on the same straight line as the extension directions of the light strips 1 .

[0105] In some embodiments, multiple light strips 1 connected by the connecting portion 18 are arranged on at least one side of the connector 20, so that the spacing between the light strips 1 on both sides connected to the connector 20 along the extension direction of the light strips 1 is not limited to the size after plugging in, reducing the spacing width between the multiple light strips 1 on at least one side and the connector 20, avoiding occupying too much space between the light strips 1 connected on both sides of the connector 20 after plugging in, thereby ensuring the luminous effect of the display device.

[0106] As shown in Figure 11, multiple light strips 1 are distributed on both sides of the connector 20, and the multiple light strips 1 on both sides are connected through a connecting portion 18. At least one first plug-in portion 301 is provided on the connecting portion 18. The second plug-in portion 302 and the fourth plug-in portion 312 are provided on both sides of the connector 20 corresponding to the first plug-in portion 301 and the third plug-in portion 311 respectively. The first plug-in portion 301 and the second plug-in portion 302 are plug-inly provided.

[0107] In one embodiment, the second plug-in portion 302 and the fourth plug-in portion 312 are not aligned with the extension direction of the plurality of light strips 1. With this arrangement, when the second plug-in portions 302 on either side of the connector 20 are plugged into the first plug-in portion 301, they do not occupy excessive space between the light strips 1 connected to either side of the connector 20, thereby ensuring the lighting effect of the display device.

[0108] In one embodiment, the second plug-in portion 302 and the fourth plug-in portion 312 are staggered. In one embodiment, the second plug-in portion 302 and the fourth plug-in portion 312 are oppositely arranged. The present disclosure does not impose any restrictions on this. As long as the extension directions of the light strips 1 on both sides of the connector 20 can be located on the same straight line and the multiple light-emitting elements 10 are evenly spaced, it is sufficient to ensure that multiple partitions of the backlight module have a uniform brightness lighting effect.

[0109] The number of the first plug-in parts 301 is specifically set according to actual needs, which can reduce the density of the second plug-in parts 302 in the length direction of the connector 20 (i.e., the up and down direction in Figure 11), reduce the plug-in steps, and make the installation of the light strip 1 more convenient.

[0110] The installation method between the light bar 1 and the connector 20 in the display device provided by the present disclosure is not limited to the above-mentioned installation method. As long as the position of the connecting portion can be reasonably set and the shape of the light bar 1 or the connector 20 can be adjusted accordingly, so that the spacing between the light bars 1 on both sides of the connector 20 can be reduced and the density requirement of the light-emitting element 10 can be met, as long as it does not deviate from the inventive concept of the present disclosure, it should be within the scope of protection of the present disclosure.

[0111] The backlight module is arranged on the back of the display panel. The display device can adjust the light-emitting elements 10 in the backlight module according to the picture on the display panel. In the area with high brightness, the backlight brightness can be increased, and in the area with low brightness, the backlight brightness can be reduced, so that the bright part is brighter and the dark part has more layers. At the same time, when the light-emitting elements 10 in the black area are turned off, the light leakage problem when displaying the black picture can be avoided, the contrast between the light and dark parts can be improved, the picture effect can be improved, the layering of the picture can be enriched, and the color transition can be more natural.
