[0022] Common display devices, such as FALD (Full Array Local Dimming) TVs, can improve contrast by controlling the brightness of the backlight LEDs (light-emitting diodes) according to different screen images, providing consumers with better picture quality and energy savings, and are therefore widely recognized by consumers. In large-size display devices, the internal LED bar consists of two segments, each with a connector, and the two segments are electrically connected via the connector. Each segment includes a PCB board and LEDs and lenses soldered onto the PCB board. The PCB board is a significant component of the LED bar's cost, accounting for a large portion of the overall cost. As LED current increases, the number of pins used in connectors is also increasing, leading to larger circuit board areas and higher costs.

[0023] This utility model proposes a light strip structure.

[0024] Please see Figure 1 In one embodiment of this utility model, the light strip structure 10 includes a light strip 1, which includes a circuit board body 11, LED beads 12, and an electrical connector 13. The circuit board body 11 includes a mounting section 111 and a connecting section 112 arranged sequentially along its length. The LED beads 12 are disposed in the mounting section 111. The electrical connector 13 is disposed in the connecting section 112 and is electrically connected to the LED beads 12. The width of the connecting section 112 of the circuit board body 11 is greater than the width of the mounting section 111.

[0025] In the technical solution of this utility model, by setting the electrical connector 13 in the connecting section 112 and setting the lamp bead 12 in the mounting section 111, and by making the width of the connecting section 112 greater than the width of the mounting section 111, installation space can be provided for the pins of the electrical connector 13, so as to ensure the installation of the electrical connector 13. Furthermore, by reducing the width of the mounting section 111, the area of ​​the circuit board body 11 is reduced, thereby reducing the overall cost of the circuit board body 11.

[0026] The circuit board body 11 can be a single-layer circuit board or a multi-layer circuit board, which is not limited here; the circuit board body 11 can also be a flexible circuit board, which is not limited here. Multiple LED beads 12 can be arranged on the mounting section 111, and the number and spacing of the LED beads 12 can be set as needed. The LED beads 12 can be LEDs, or any other feasible type of LED beads 12, which is not limited here. The mounting section 111 and the connecting section 112 are integrally printed, and the length of the mounting section 111 is greater than the length of the connecting section 112. At least some of the pins of the electrical connector 13 are spaced apart along the width direction of the connecting section 112; specifically, all the pins of the electrical connector 13 are spaced apart along the width direction of the connecting section 112. The electrical connector 13 and the LED beads 12 are electrically connected through printed circuits on the circuit board body 11.

[0027] Please see Figure 2 In one embodiment of this utility model, a first connector 2 is provided on the mounting section 111 of the circuit board body 11. The first connector 2 is used to connect a power supply wire. After the circuit board body 11 is placed inside the display, by electrically connecting the power supply wire to the first connector 2, power can be supplied to the circuit board body 11 to control the operating state of the LED beads 12 on the circuit board body 11.

[0028] The power supply wire can control the on / off switching of power to any one or more of the plurality of LED beads 12 to adjust the backlight of the display. When two LED strips 1 are connected through the electrical connector 13, either one LED strip 1 can be electrically connected to the power supply wire through the first connector 2, or both LED strips 1 can be electrically connected to the power supply wire through the first connector 2; this is not limited here. Specifically, one of the two LED strips 1 is provided with the first electrical connector 13 and electrically connected to the power supply wire, and the two LED strips 1 are electrically connected to each other through the electrical connector 13 to realize the power supply wire supplying power to the two LED strips 1.

[0029] In one embodiment of this utility model, one end of the connecting segment 112 protrudes relative to the mounting segment 111 in its width direction. By making one end of the connecting segment 112 protrude relative to the mounting segment 111 in its width direction, the width of the connecting segment 112 can be greater than the width of the mounting segment 111.

[0030] In one embodiment of this utility model, the connecting segment 112 protrudes from the mounting segment 111 at both opposite ends in its width direction. By making the connecting segment 112 protrude from the mounting segment 111 at both opposite ends in its width direction, the width of the connecting segment 112 is greater than the width of the mounting segment 111. In addition, it also makes the light strips 1 symmetrical, and when two light strips 1 are connected, the two light strips 1 can be made coaxial.

[0031] In one embodiment of this utility model, two light strips 1 are provided. The electrical connector 13 provided on one of the light strips 1 is the second connector 131, and the electrical connector 13 provided on the other light strip 1 is the third connector 132. The first connector 2 has a socket, and the second connector 131 has a plug. The plug is inserted into the socket to electrically connect the two connectors.

[0032] By inserting the plug into the socket, the two light strips 1 can be electrically connected, which is simple and convenient. When the display size is large, connecting the two light strips 1 allows the light strip structure 10 to adapt to the length of the display, ensuring backlighting for the display. When the two light strips 1 are connected, they can partially overlap, with the LEDs 12 of the two light strips 1 located on the same side of the two light strips 1, and the connectors of the two light strips 1 located on the side of the two light strips 1 that are close to each other.

[0033] Please see Figure 3 or Figure 4This utility model also proposes a lamp panel structure 20, which includes a plurality of lamp strips 3 to be formed. The lamp strips 3 are used to form the lamp strip 1. The specific structure of the lamp strip 1 is as described in the above embodiments. Since this lamp panel structure 20 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the plurality of lamp strips 3 to be formed are arranged along their width direction. In two adjacent lamp strips 3 to be formed, the mounting sections 111 of the two lamp strips 3 to be formed are arranged in parallel. The connecting section 112 of the two lamp strips 3 to be formed is located at the ends of the two lamp strips 3 to be formed that are far apart from each other. One end of one of the mounting sections 111 protrudes in the length direction from the same end of the other mounting section 111 and is connected to the connecting section 112.

[0034] By printing multiple LED strips 3 to be formed simultaneously, the printing of individual LED strips 3 is avoided, thus improving the printing efficiency. By arranging the mounting sections 111 of the LED strips 3 in parallel and placing the connecting section 112 at the ends of two LED strips 3 that are far apart, the width of the mounting sections 111 is reduced while the width of the connecting section 112 is increased, thereby improving the overall utilization rate of the circuit board 11. While ensuring the installation of the electrical connector 13 on the connecting section 112, the width of the mounting sections 111 is reduced, thus reducing the area of ​​a single LED strip 3 and lowering costs.

[0035] In one embodiment of this utility model, a separation groove is provided between adjacent light strips 3 to be formed. After printing multiple light strips 3 to be formed, the separation groove facilitates the classification of the light strips 1. The separation groove can be manually drawn or machine-cut, and is not limited here.

[0036] In one embodiment of the present invention, the mounting section 111 of the light strip to be formed 3 includes a plurality of lamp bead portions 31 and a plurality of connecting portions 32. The plurality of lamp bead portions 31 and the plurality of connecting portions 32 on the light strip to be formed 3 are arranged alternately at intervals along its length direction. In two adjacent light strips to be formed 3, the lamp bead portion 31 of one light strip to be formed 3 is at least partially disposed opposite to the connecting portion 32 of the other light strip to be formed 3.

[0037] By staggering the lamp bead portions 31 of adjacent lamp strips 3 to be formed, the distance between the lamp beads 12 of adjacent lamp strips 3 to be formed can be reduced. This facilitates the installation of the lamp beads 12, avoids interference between them, and reduces the difficulty of operation. All lamp bead portions 31 can be arranged corresponding to the connecting portions 32.

[0038] Please see Figure 5 This utility model also proposes a backlight module 100, which includes the aforementioned lamp strip structure 10. The specific structure of the lamp strip structure 10 is as described in the above embodiments. Since this backlight module 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The backlight module 100 is used in a display device.

[0039] While ensuring the installation of the electrical connector 13 on the connection section 112, the width of the mounting section 111 of the light strip 1 is reduced, the area of ​​the circuit board body 11 of the light strip 1 is reduced, the cost of the light strip 1 is reduced, and thus the cost of the display device is reduced.

[0040] The light strip structure 10 extends along the left-right direction of the backlight module 100, and multiple light strip structures 10 are provided, spaced apart. The multiple light strips 10 cooperate to ensure the backlight effect of the backlight module 100.

[0041] Two light strips 1 are arranged in the left-right direction, and the two light strips 1 are electrically connected to each other through the electrical connector 13.

[0042] Please see Figure 5 This utility model also proposes a display device, including the backlight module 100. While ensuring the installation of the electrical connector 13 on the connection section 112, the width of the mounting section 111 of the lamp strip 1 is reduced, and the width of the circuit board body 11 is reduced, thereby reducing the cost of the circuit board body 11, thus reducing the cost of the lamp strip 1 and the backlight module 100, and thus reducing the cost of the display device.

[0043] The display device can be a television, a monitor, or any display device with display function, and is not limited thereto; specifically, the display device is a television. The display device also includes a housing, and the backlight module 100 is disposed within the housing.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
