[0063] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the light strip and connector provided in this application.

[0065] like Figure 1 As shown, in existing technology, a contact point is set at one end of the glass-based light strip, and a slot is used to connect it to the connector. This solution is prone to damage from repeated disassembly and reassembly of the positioning components, and the connector can only be located at the end of the light strip, resulting in a fixed position, which is not conducive to narrow bezel designs.

[0066] Please see Figures 2 to 4 , Figure 2 This is a schematic diagram of the structure of the first embodiment of the light-emitting device provided in this application. Figure 3 This is a schematic diagram of the structure of the second embodiment of the light-emitting device provided in this application. Figure 4 This is a schematic diagram of the structure of the third embodiment of the light-emitting device provided in this application.

[0067] This application provides a light-emitting device 1 (see...) Figure 16The light-emitting device 1 includes a connector 10, a carrier plate 20, and a light strip 30. The connector 10 includes a main body 12 (see...). Figure 5 The light-emitting device 1 also includes a connecting contact 11; a light strip 30 having an electrode contact 31; the light strip 30 is partially sandwiched between the main body 12 and the carrier plate 20, and the electrode contact 31 and the connecting contact 11 are arranged opposite to each other; wherein, the light-emitting device 1 also includes a driving member 40; the driving member 40 controls the relative displacement between the carrier plate 20 and the connector 10 to clamp or release the light strip 30, thereby realizing the on / off state of the electrode contact 31 and the connecting contact 11.

[0068] The relative displacement between the carrier plate 20 and the connector 10 is controlled by the drive unit 40 to clamp and release the light strip 30 sandwiched between the carrier plate 20 and the connector 10, thereby realizing the electrical connection between the light strip 30 and the connector 10. In addition, the light strip 30 and the connector 10 can be detached, making it easy to replace the connector 10.

[0069] Connector 10, used for connecting and fixing the light strip 30, is plate-shaped or ring-shaped. Under the driving action of the driving member 40, relative displacement can be achieved between connector 10 and carrier plate 20, bringing connector 10 and carrier plate 20 closer together, thereby reducing the movement space of light strip 30 between connector 10 and carrier plate 20, restricting the movement of light strip 30, and fixing light strip 30; and moving connector 10 and carrier plate 20 further apart, thereby increasing the movement space of light strip 30 between connector 10 and carrier plate 20, and releasing light strip 30.

[0070] The carrier plate 20 is plate-shaped. The carrier plate 20 carries the light strip 30 and drives the light strip 30 to move together, so as to connect the contact point 11 with the electrode contact 31 located on the light strip 30.

[0071] The light strip 30 is inserted into the space between the connector 10 and the carrier plate 20 along its own length. The electrode contact 31 is disposed on the light strip 30 and is disposed corresponding to the connection contact 11, so that when the carrier plate 20 and the connector 10 clamp the light strip 30, the electrode contact 31 can abut against the connection contact 11 to achieve electrical connection.

[0072] In some embodiments, the light strip 30 further includes a circuit board 32 and a light-emitting element 33 (see Figure 5 The light-emitting element 33 is disposed on one side of the circuit board 32; the electrode contact 31 is located on the side of the circuit board 32 facing the light-emitting element 33 and is disposed towards the first sidewall 122.

[0073] The circuit board 32 is electrically connected to the light-emitting element 33 and drives the light-emitting element 33 to emit light. The electrode contact 31 is the contact of the circuit board 32, and the circuit board 32 is connected to the power supply through the electrode contact 31. Specifically, the circuit board 32 is electrically connected to the connector 10 through the electrode contact 31 and the connection contact 11.

[0074] For example, the light-emitting element 33 is a light-emitting diode (LED).

[0075] For example, each light bar 30 includes a row of light-emitting elements 33 arranged along the length of the light bar 30.

[0076] The size and arrangement of the light-emitting elements 33 are not limited here and can be selected according to actual needs. In other embodiments, the light strip 30 may include at least two rows of light-emitting elements 33.

[0077] For example, circuit board 32 is obtained by printing circuitry on a glass substrate.

[0078] For example, circuit board 32 is obtained by printing circuitry on scrap glass.

[0079] For example, electrode contacts 31 are provided on the surface of circuit board 32 near the first sidewall 122, and connection contacts 11 are provided on the surface of the first sidewall 122 facing the second sidewall 123.

[0080] In other embodiments, the electrode contact 31 is embedded in the circuit board 32, or the connecting contact 11 is embedded in the first sidewall 122.

[0081] The drive unit 40 is used to drive the carrier plate 20 and / or connector 10 to move.

[0082] There is at least one drive component 40; no restriction is imposed here, and the choice is made according to actual needs.

[0083] In some embodiments, the drive member 40 is a stud 41. In other embodiments, the drive member 40 is a combination of a nut 42 and a stud 41.

[0084] In some embodiments, the connector 10 has a plate-like structure and is disposed opposite to the carrier plate 20. That is, the main body 12 has a plate-like structure and is disposed opposite to the carrier plate 20.

[0085] In one specific embodiment, the driving component 40 is a combination structure of a nut 42 and a stud 41. The stud 41 is fixed to the side of the connector 10 facing the carrier plate 20 and passes through the carrier plate 20. The nut 42 is provided on the side of the carrier plate 20 away from the connector 10, and the nut 42 and the stud 41 are threadedly connected to each other extending out of the carrier plate 20. Rotating the nut 42 moves the nut 42 toward the connector 10, thereby displacing the carrier plate 20 toward the connector 10 until it clamps the lamp strip 30 and causes the electrode contact 31 to abut against the connecting contact 11, thus achieving an electrical connection between the lamp strip 30 and the connector 10. Rotating the nut 42 moves the nut 42 away from the connector 10, thereby displacing the carrier plate 20 away from the connector 10, thereby disengaging the electrode contact 31 from the connecting contact 11 and releasing the lamp strip 30.

[0086] In another specific embodiment, a stud 41 is fixed to the side of the carrier plate 20 facing the connector 10 and passes through the connector 10. A nut 42 is provided on the side of the connector 10 away from the carrier plate 20, and the nut 42 is threadedly connected to the stud 41 extending out of the connector 10. Rotating the nut 42 moves the nut 42 toward the carrier plate 20, causing the connector 10 to move toward the carrier plate 20 until it clamps the lamp strip 30 and causes the electrode contact 31 to abut against the connecting contact 11, thus achieving an electrical connection between the lamp strip 30 and the connector 10. Rotating the nut 42 moves the nut 42 away from the carrier plate 20, causing the connector 10 to move away from the carrier plate 20, thus disengaging the electrode contact 31 from the connecting contact 11 and releasing the lamp strip 30.

[0087] In another specific embodiment, a stud 41 passes through both the connector 10 and the carrier plate 20. A nut 42 is provided on the side of the carrier plate 20 away from the connector 10, and a nut 42 is also provided on the side of the connector 10 away from the carrier plate 20. The nuts 42 are threadedly connected to the portions of the stud 41 extending out of the connector 10 and the carrier plate 20, respectively. By rotating the nut 42, the connector 10 and / or the carrier plate 20 are displaced relative to each other, thereby clamping or releasing the lamp strip 30 and switching the electrode contact 31 on and off with the connecting contact 11.

[0088] By using the plate-shaped connector 10, the carrier plate 20, and the corresponding various driving components 40, the light strip 30 is fixed with a simpler connector 10 structure. At the same time, the position and structure of the driving components 40 are flexibly set to adapt to more usage scenarios and save costs.

[0089] Please see Figures 5 to 8 , Figure 5 This is a schematic diagram of the structure of the fourth embodiment of the light-emitting device provided in this application. Figure 6 This is a schematic diagram of the structure of the fifth embodiment of the light-emitting device provided in this application. Figure 7This is a schematic diagram of the structure of the sixth embodiment of the light-emitting device provided in this application. Figure 8 This is a structural schematic diagram of the seventh embodiment of the light-emitting device provided in this application.

[0090] In some embodiments, the main body 12 has a groove 121, the groove 121 being in a first direction x1 (see...). Figure 16 The main body 12 is penetrated by the groove 121; the two side walls of the groove 121 respectively constitute the main body 12 along the second direction y1 (see Figure 16 The first sidewall 122 and the second sidewall 123 are opposite to each other; the first direction x1 and the second direction y1 are intersected; the lamp strip 30 is partially placed in the groove 121 along the first direction x1; the carrier plate 20 is located in the groove 121; the lamp strip 30 is located on the side of the carrier plate 20 facing the first sidewall 122; the driving member 40 is located on the side of the carrier plate 20 close to the second sidewall 123; the driving member 40 is threadedly connected to the second sidewall 123, and the displacement of the carrier plate 20 in the second direction y1 is controlled by rotating the driving member 40, so as to realize the opening and closing of the electrode contact 31 and the connecting contact 11.

[0091] The main body 12 has a ring-shaped structure and an internal groove 121 that extends along the first direction x1. The first sidewall 122 and the second sidewall 123 of the main body 12 are arranged opposite to each other in the second direction y1, serving as the two opposite sidewalls of the groove 121 in the second direction y1.

[0092] For example, the first direction x1 is perpendicular to the second direction y1, and the main body 12 is a rectangular ring structure.

[0093] For example, the drive member 40 is a screw including a stud 41. One end of the drive member 40 is located outside the connector 10 (i.e., the screw head is located outside the connector 10 to facilitate screw rotation), passes through the threaded hole 124 through the second sidewall 123 of the connector 10, and abuts against the carrier plate 20. By rotating the drive member 40, the carrier plate 20 is moved, thereby adjusting the distance between the carrier plate 20 and the first sidewall 122, and causing the lamp strip 30 to follow the movement of the carrier plate 20, thereby clamping or releasing the lamp strip 30 to achieve the switching of the electrode contact 31 and the connecting contact 11.

[0094] Specifically, in the initial state, the carrier plate 20 is located inside the groove 121 and close to the second side wall 123. The lamp strip 30 is inserted into the groove 121 along the first direction x1 and is located on the side of the carrier plate 20 facing the first side wall 122. At this time, the electrode contact 31 of the lamp strip 30 is not in contact with the connecting contact 11, the lamp strip 30 is located between the carrier plate 20 and the first side wall 122, and is in a released state.

[0095] While the carrier plate 20 is moving towards the first sidewall 122 along the second direction y1, after the lamp strip 30 is inserted into the preset position of the slot 121, the driving member 40 is screwed in. The driving member 40 pushes the carrier plate 20 to move towards the first sidewall 122 along the second direction y1 through threaded transmission. The carrier plate 20 drives the lamp strip 30 to move synchronously, so that the electrode contacts 31 on the lamp strip 30 gradually approach and finally abut against the connection contact 11, clamping the lamp strip 30, realizing electrical connection and fixed connection between the lamp strip 30 and the connector 10.

[0096] Compared to the plate-shaped design of connector 10, setting connector 10 as a ring-shaped structure can limit the position of light strip 30 and carrier plate 20 along the width direction of light strip 30, making it easier to clamp or release light strip 30.

[0097] In other embodiments, the drive member 40 includes a stud 41 and a nut 42. The stud 41 may be disposed on the surface of the carrier plate 20 facing the first sidewall 122 and located on opposite sides of the carrier plate 20 along the second direction y1. The nut 42 is located outside the connector 10. The stud 41 passes through the first sidewall 122 of the body portion 12 and the portion extending out of the connector 10 is threadedly connected to the nut 42.

[0098] In some embodiments, the light-emitting device 1 further includes a plurality of limiting posts 51 extending along a second direction y1, the limiting posts 51 extending along a third direction z1 (see... Figure 15 The first side wall 122 and the carrier plate 20 are located on opposite sides of the light strip 30; the third direction z1 is set perpendicular to the first direction x1 and perpendicular to the second direction y1; the limiting post 51 is located between the first side wall 122 and the carrier plate 20 and is fixed to the first side wall 122 or the carrier plate 20.

[0099] The limiting posts 51 extend along the second direction y1. There are at least two limiting posts 51, used to further limit the light strip 30 in the third direction z1, preventing poor electrical connection between the electrode contacts 31 and the connecting contacts 11 due to misalignment. In some embodiments, the limiting posts 51 are located on the first sidewall 122 or the carrier plate 20; or in other embodiments, some of the limiting posts 51 are located on the first sidewall 122, and others are located on the carrier plate 20.

[0100] For example, the limiting post 51 can be cylindrical or other columnar structures.

[0101] The following description mainly uses the example of the driving component 40 being located on the side of the carrier plate 20 away from the first side wall 122 and passing through the second side wall 123.

[0102] In one specific embodiment, the limiting post 51 is located on the side of the carrier plate 20 near the first side wall 122. When clamping the light strip 30, the limiting post 51 is spaced apart from the first side wall 122 to prevent the limiting post 51 from being too long and prematurely abutting against the first side wall 122 before the light strip 30 is clamped, thus preventing the light strip 30 from being clamped.

[0103] In another specific embodiment, the limiting post 51 is located on the side of the first sidewall 122 near the second sidewall 123. When clamping the light strip 30, the limiting post 51 is spaced apart from the carrier plate 20 to prevent the limiting post 51 from being too long and prematurely abutting against the carrier plate 20 before the light strip 30 is clamped, thus preventing the light strip 30 from being clamped.

[0104] Please see Figures 9 to 10 , Figure 9 This is a schematic diagram of the structure of the eighth embodiment of the light-emitting device provided in this application. Figure 10 This is a structural schematic diagram of the ninth embodiment of the light-emitting device provided in this application.

[0105] In other embodiments, the light-emitting device 1 further includes an elastic element 52. By providing the elastic element 52, elastic potential energy can be used to assist in the release of the light strip 30 during the release process.

[0106] For example, the elastic element 52 is a spring 521, which is sleeved on the outer periphery of the limiting post 51 and extends partially beyond the limiting post 51. When the electrode contact 31 abuts against the connecting contact 11, the elastic element 52 is in a compressed state. When the electrode contact 31 separates from the connecting contact 11, under the action of the elastic potential energy of the elastic element 52, the elastic element 52 will apply an elastic thrust to the limiting post 51 in the direction toward the carrier plate 20, assisting the carrier plate 20 to move away from the first sidewall 122, so as to release the lamp strip 30.

[0107] For example, the elastic element 52 is a spring 521 or a sheet spring, etc. The elastic element 52 is fixed to the end of the limiting post 51. Similarly, the provision of the elastic element 52 facilitates the release of the light strip 30. In a specific embodiment, the limiting post 51 is located on the side of the carrier plate 20 near the first side wall 122, and the elastic element 52 is fixed to the end of the limiting post 51 facing the first side wall 122.

[0108] In other embodiments, the limiting post 51 is located on the side of the first sidewall 122 near the carrier plate 20, and the elastic element 52 is fixed to the end of the limiting post 51 facing the carrier plate 20.

[0109] Please see Figures 11 to 15 , Figure 11 This is a structural schematic diagram of the tenth embodiment of the light-emitting device provided in this application. Figure 12 This is a schematic diagram of the eleventh embodiment of the light-emitting device provided in this application. Figure 13 This is a schematic diagram of the structure of the twelfth embodiment of the light-emitting device provided in this application. Figure 14 This is a schematic diagram of the structure of the light-emitting device in the thirteenth embodiment provided in this application, with the light strip in the released state. Figure 15 This is a schematic diagram of the structure of the light-emitting device provided in the thirteenth embodiment of the present application, in which the light strip is in a clamped state.

[0110] In some embodiments, the light-emitting device 1 further includes a limiting groove 53, which is disposed on the surface of the first sidewall 122 facing the second sidewall 123, or the limiting groove 53 is disposed on the surface of the carrier plate 20 facing the first sidewall 122; the limiting groove 53 and the limiting post 51 are respectively disposed in a one-to-one correspondence; wherein, when the connecting contact point 11 and the electrode contact point 31 are in an abutting state, the limiting post 51 is inserted into the corresponding limiting groove 53 and is spaced apart from the bottom wall of the limiting groove 53; or, the light-emitting device 1 further includes an elastic element 52, which is disposed in a way that is perpendicular to the limiting post 53. The end of the positioning post 51 near the limiting groove 53 is connected, and / or the elastic element 52 is connected to the bottom wall of the limiting groove 53; when the connecting contact point 11 and the electrode contact point 31 are in abutting state, the elastic element 52 is in a compressed state, and the elastic element 52 is at least partially located within the limiting groove 53; or, the light-emitting device 1 further includes a spring 521, which is sleeved on the outer periphery of the positioning post 51, and the spring 521 is at least partially located outside the limiting groove 53; when the connecting contact point 11 and the electrode contact 31 are in abutting state, the elastic element 52 is in a compressed state.

[0111] When the contact point 11 and the electrode contact point 31 are in contact, the cooperation of the limiting groove 53 and the limiting post 51 can limit the displacement of the carrier plate 20 in the third direction z1, thereby limiting the displacement of the lamp strip 30.

[0112] The limiting groove 53 is disposed on the surface of the first sidewall 122 facing the second sidewall 123, or the limiting groove 53 is disposed on the surface of the carrier plate 20 facing the first sidewall 122. The following description mainly takes the case where the limiting groove 53 is disposed on the surface of the first sidewall 122 facing the second sidewall 123 as an example.

[0113] In the first specific embodiment, such as Figure 11 As shown, when the connecting contact 11 and the electrode contact 31 are in abutting state, the limiting post 51 is inserted into the corresponding limiting groove 53 and is spaced apart from the bottom wall of the limiting groove 53. That is, this embodiment does not include the elastic element 52. Specifically, the limiting post 51 is disposed on the side of the carrier plate 20 near the first side wall 122. The setting of the limiting groove 53 can not only limit the limiting post 51, but also prevent the limiting post 51 from interfering with the abutting between the connecting contact 11 and the electrode contact 31.

[0114] In the second specific embodiment, such as Figure 12As shown, the light-emitting device 1 also includes an elastic element 52, which is connected to the end of the limiting post 51 near the limiting groove 53, and / or the elastic element 52 is connected to the bottom wall of the limiting groove 53. When the contact point 11 and the electrode contact point 31 are in abutting state, the elastic element 52 is in a compressed state, and the elastic element 52 is at least partially located within the limiting groove 53. The limiting groove 53 can also limit the elastic element 52 to prevent lateral displacement. The length of the elastic element 52 in its natural state can be greater than, less than, or equal to the depth of the limiting groove 53; there is no specific limitation, and it can be selected according to actual needs.

[0115] In the third specific embodiment, the light-emitting device 1 further includes a spring 521, which is sleeved on the outer periphery of the limiting post 51, and the spring 521 is at least partially located outside the limiting groove 53; when the connecting contact point 11 and the electrode contact point 31 are in abutting state, the elastic member 52 is in a compressed state.

[0116] Exemplarily, in some embodiments, such as Figure 13 As shown, spring 521 is sleeved on the outer periphery of limiting post 51, and spring 521 is located outside limiting groove 53. Spring 521 and limiting post 51 can be fixedly connected or not fixedly connected; there are no strict restrictions here, and the choice can be made according to actual needs. It should be noted that when spring 521 and limiting post 51 are not fixedly connected, spring 521 abuts against the first side wall 122 and the carrier plate 20 in its natural state to ensure that spring 521 will not fall off during the release or clamping of lamp strip 30. When spring 521 and limiting post 51 are not fixedly connected, spring 521 can also be fixed inside limiting groove 53 or on first side wall 122.

[0117] In other embodiments, such as Figure 14 and Figure 15 As shown, spring 521 is sleeved on the outer periphery of limiting post 51, and part of spring 521 is located outside limiting groove 53. The portion of spring 521 extending out of limiting post 51 is at least partially located within limiting groove 53.

[0118] The functions of the elastic element 52 and the spring 521 are as described above and will not be repeated here.

[0119] Please see Figures 16 to 19 , Figure 16 This is a three-dimensional structural schematic diagram of the fourteenth embodiment of the light-emitting device provided in this application. Figure 17 This is a structural schematic diagram from another perspective of the fourteenth embodiment of the light-emitting device provided in this application. Figure 18 This is a schematic diagram of the structure of the fifteenth embodiment of the light-emitting device provided in this application. Figure 19 This is a schematic diagram of the structure of the sixteenth embodiment of the light-emitting device provided in this application.

[0120] In some embodiments, the electrode contact 31 is located in the middle region 300 of the circuit board 32 along the first direction x1; the lamp strip 30 passes through the groove 121 along the first direction x1.

[0121] Connector 10 clamps a light strip 30. This can be understood as connector 10 clamping the light strip 30 in the middle region 300 along the first direction x1.

[0122] Each light strip 30 has two end regions 200 and a middle region 300, with the middle region 300 located between the two end regions 200.

[0123] In some specific embodiments, such as Figure 16 and Figure 17 As shown, electrode contacts 31 are located on the surface of circuit board 32 facing the light-emitting element 33, and are disposed on opposite sides of the circuit board 32 along the third direction z1. That is, electrode contacts 31 are located on the side of the light-emitting element 33 along the third direction z1 to facilitate electrical connection with the connection contacts 11 of connector 10. In other specific embodiments, such as Figure 18 As shown, electrode contacts 31 are located on the surface of circuit board 32 facing the light-emitting element 33 and are located between the light-emitting elements 33.

[0124] Compared to existing technologies, the connector 10 is clamped in the middle region 300 of the light strip 30 along the first direction x1, which avoids occupying the end space of the light strip 30, which is conducive to achieving a narrow frame design, and facilitates the disassembly and replacement of the connector 10 without damaging the light strip 30.

[0125] In other embodiments, such as Figure 19 As shown, the electrode contact 31 is located in the end region 200 of the circuit board 32 along the first direction x1; in the first direction x1, the end regions 200 of two adjacent light strips 30 that are close to each other are respectively inserted into the slot 121 of the same connector 10, so as to realize the parallel arrangement of two adjacent light strips 30 through the connector 10.

[0126] This can be understood as a connector 10 simultaneously clamping two light strips 30 to achieve splicing of the light strips 30 in the first direction x1, thereby improving the problem that the size of a single scrap light strip 30 is insufficient to meet the needs of a large-size display device 2.

[0127] Please see Figures 20 to 21 , Figure 20 This is a schematic diagram of the structure of the seventeenth embodiment of the light-emitting device provided in this application. Figure 21 This is a schematic diagram of the structure of the eighteenth embodiment of the light-emitting device provided in this application.

[0128] In some embodiments, the connector 10 further includes a compensation light source 125 disposed on the surface of the first sidewall 122 away from the second sidewall 123.

[0129] The compensation light source 125 is used to supplement the light strip 30.

[0130] In some specific embodiments, in the first direction x1, the connector 10 is clamped between two adjacent light-emitting elements 33, that is, the first sidewall 122 is located between two adjacent light-emitting elements 33 (see...). Figure 18 Specifically, the first sidewall 122 of the connector 10 can be located between two adjacent light-emitting elements 33 of the same light strip 30, or at the junction of two light strips 30. Since the connector 10 is sandwiched between the light-emitting elements 33, it increases the spacing between the two adjacent light-emitting elements 33, weakening the light intensity at that location and negatively impacting light emission uniformity. Therefore, a compensation light source 125 is provided on the connector 10 to compensate for the light intensity at the location of the connector 10, thereby improving display uniformity.

[0131] In other embodiments, in the second direction y1, the first sidewall 122 of the connector 10 blocks at least one light-emitting element 33. That is, at least one light-emitting element 33 enters the groove 121. Each light-emitting element 33 is at least partially located within the groove 121.

[0132] For example, a light-emitting element 33 is entirely located within the groove 121.

[0133] The first sidewall 122 blocks the emitted light from the light-emitting element 33, causing abnormal light emission from the light strip 30. By providing a compensation light source 125 on the connector 10 to replace the light-emitting element 33 that is blocked by the connector 10, the uniformity of the display is improved.

[0134] In some embodiments, the first sidewall 122 has a light-transmitting area 100; the light-transmitting area 100 extends through the first sidewall 122 along the first direction x1 and the second direction y1; when the connecting contact point 11 and the electrode contact point 31 are in a contact state, the light-transmitting area 100 avoids the light-emitting element 33, or at least one light-emitting element 33 is located in the light-transmitting area 100.

[0135] The first sidewall 122 can be made of a light-transmitting material to form a light-transmitting area 100, or it can be hollowed out to form a light-transmitting area 100.

[0136] For example, the first sidewall 122 is etched to form a light-transmitting area 100 to avoid wear caused by collision between the light-emitting element 33 located in the groove 121 and the first sidewall 122 during the clamping of the lamp strip 30.

[0137] When the contact point 11 and the electrode contact point 31 are in contact, the light-transmitting area 100 is positioned to avoid the light-emitting element 33, that is, the first sidewall 122 is located on the side of the light-emitting element 33 along the third direction z1 (see...). Figure 16 and Figure 17 ).

[0138] The light-emitting element 33 is located in the light-transmitting area 100 (see Figure 13 (etc.) to avoid the first sidewall 122 occupying the space between the light-emitting elements 33, which would increase the spacing between the light-emitting elements 33 and affect the light-emitting effect.

[0139] In some embodiments, the contact point 11 may extend to the light-transmitting area 100.

[0140] Please see Figures 22 to 25 , Figure 22 This is a schematic diagram of the structure of the nineteenth embodiment of the light-emitting device provided in this application. Figure 23 This is a schematic diagram of the structure of the twentieth embodiment of the light-emitting device provided in this application. Figure 24 This is a schematic diagram of an embodiment of the light strip and connector provided in this application. Figure 25 This is a schematic diagram of another embodiment of the light strip and connector provided in this application.

[0141] In some embodiments, such as Figure 22 As shown, the circuit board 32 of the light strip 30 has a mounting groove 54 on the side facing the first sidewall 122. The electrode contact 31 is located on the bottom wall of the mounting groove 54. When the light strip 30 is inserted into the groove 121, the connecting contact 11 corresponds to the electrode contact 31. That is, the electrode contact 31 is embedded in the first sidewall 122 and abuts against the connecting contact 11. When the carrier plate 20 moves toward the first sidewall 122, the connecting contact 11 and the electrode contact 31 approach each other, and the connecting contact 11 continuously approaches the mounting groove 54 and is inserted into the mounting groove 54, abutting against the electrode contact 31. The mounting groove 54 restricts the displacement of the light strip 30 in the third direction z1, and also makes the abutment between the connecting contact 11 and the electrode contact 31 more stable, which is beneficial to the electrical connection stability of the light strip 30.

[0142] In other embodiments, the mounting groove 54 is disposed on the side of the first sidewall 122 of the main body 12 facing the second sidewall 123, and the contact point 11 is disposed on the bottom wall of the mounting groove 54, which serves the same limiting function.

[0143] In some embodiments, such as Figure 23As shown, the light-emitting device 1 also includes a magnetic attractor 55 and a magnetic element 56. One of the magnetic attractor 55 and the magnetic element 56 is disposed on the light strip 30, and the other is disposed on the connector 10. The light strip 30 is positioned by the mutual attraction between the magnetic attractor 55 and the magnetic element 56, so that the electrode contact 31 of the light strip 30 can be aligned with the connecting contact 11 in the second direction y1, ensuring that the electrode contact 31 and the connecting contact 11 can abut to achieve a good electrical connection.

[0144] In other embodiments, such as Figure 24 and Figure 25 As shown, in the direction parallel to the carrier plate 20, the cross-section of the connector 10 is trapezoidal, with the upper and lower bases of the trapezoid positioned opposite each other along the first direction x1. The width of the light strip 30 along the third direction z1 gradually decreases along the first direction x1. The width of the upper base is smaller than the width of the lower base, so that during the insertion of the light strip 30 into the slot 121 of the connector 10 along the first direction x1, the narrower end of the light strip 30 passes through the lower base and exits through the upper base until it is locked in the slot 121. The upper base can limit the insertion of the light strip 30, thereby facilitating the accurate insertion of the electrode contacts 31 of the light strip 30 into the preset position of the slot 121, so that the electrode contacts 31 and the connecting contacts 11 are aligned in the second direction y1, ensuring that the electrode contacts 31 and the connecting contacts 11 can abut to achieve a good electrical connection.

[0145] For example, in the direction parallel to the carrier plate 20, the cross-section of the connector 10 is a right-angled trapezoid, and the cross-section of the light strip 30 is a matching right-angled trapezoid. The right-angled side of the right-angled trapezoid is set along the first direction x1. Designing the cross-section of the connector 10 as a right-angled trapezoid can limit the light strip 30 in the third direction z1, which facilitates the stability of the light strip 30 during the process of passing through the slot 121.

[0146] The connector 10 also includes external contacts 13, through which the connector 10 is electrically connected to an external power source.

[0147] For example, the external contact 13 is located outside the slot 121 to facilitate connection to an external power source.

[0148] In other embodiments, the external contact 13 may also be disposed on the outer wall of the connector 10. There are no major restrictions here, and the choice can be made according to actual needs.

[0149] Please see Figure 26 , Figure 26 This is a schematic diagram of an embodiment of the display device provided in this application.

[0150] This application provides a display device 2, including a display panel 3 and the aforementioned light-emitting device 1. The light-emitting device 1 provides a backlight for the display panel 3.

[0151] Display panel 3 is an LCD panel.
