[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please refer to the following: Figure 1 and Figure 2 This embodiment provides a light source assembly, which includes an adapter plate 11 and multiple lamp boards 12 located on the side of the adapter plate 11. Multiple LEDs are disposed in each lamp board 12. A connector is provided in the adapter plate 11 for connection to the lamp boards 12. Given that the connector and printed traces on the adapter plate 11 cannot be made smaller, the structural dimensions of the adapter plate 11 are relatively fixed. To ensure that the pitch value between two LEDs is equal, the adapter plate 11 cannot be adapted if the structural dimensions of the adapter plate 11 and the connector are larger than the pitch value between the two LEDs.

[0036] The adapter board 11 is electrically connected to the driver board 2, and the driver board 2 is connected to the main board 1 via a signal line. The driver board 2 drives the LEDs in the lamp board 12 to light up according to the control signal output by the main board 1.

[0037] Please see Figure 3 This embodiment provides a light source assembly, which includes an adapter plate 11 and multiple lamp panels 12 disposed on the side of the adapter plate 11. Both the lamp panels 12 and the adapter plate 11 are provided with multiple light-emitting elements 13. In this embodiment, the structural dimensions of the adapter plate 11 are directly increased, and the light-emitting elements 13 are arranged on the adapter plate 11, making full use of the space occupied by the adapter plate 11 and avoiding the limitation of the use of the adapter plate 11, so as to meet the application requirements of the regional backlight display device.

[0038] In some embodiments, the adapter plate 11 is provided with a plurality of uniformly arranged first light-emitting elements 131, and the lamp plate 12 is provided with a plurality of uniformly arranged second light-emitting elements 132; the light-emitting elements 13 located in the adapter plate 11 are used as the first light-emitting elements 131, and the light-emitting elements 13 located in the lamp plate 12 are used as the second light-emitting elements 132. In the first direction, as Figure 3 In the X direction, the first spacing between adjacent first light-emitting elements 131 and second light-emitting elements 132 and the second spacing b between two adjacent second light-emitting elements 132 are the same.

[0039] If the adapter plate 11 extends along the second direction, the lamp plate 12 is located on the side of the adapter plate 11 and extends along the first direction; the first direction is the same as the second direction (e.g., ...). Figure 3 When the Y-direction (in the first direction) intersects perpendicularly, only one column of first light-emitting elements 131 is provided in the adapter plate 11, and the first direction is the row direction of the first light-emitting elements 131 in the adapter plate 11. The first distance 'a' between the first light-emitting element 131 and the adjacent second light-emitting element 132 in the adapter plate 11 is equal to the second distance 'b' between the two second light-emitting elements 132 in the lamp board 12, ensuring that the distance between the two light-emitting elements 13 in the light source assembly is the same. Of course, in other embodiments, the adapter plate 11 may also extend along the first direction, while the lamp board 12 may extend along the second direction, and this application does not limit this.

[0040] Please see Figure 4 In some embodiments, the multiple first light-emitting elements 131 in the adapter plate 11 are arranged in an array to form two or more columns. In the first direction, the third spacing c between two adjacent first light-emitting elements 131 is the same as the second spacing b. In order to avoid the minimum structural size of the adapter plate 11 being limited, the structural size of the adapter plate 11 is expanded by directly setting multiple light-emitting elements 13 in the adapter plate 11, and ensuring that the third spacing c between the first light-emitting elements 131 in the adapter plate 11 is consistent with the second spacing b between the second light-emitting elements 132 in the lamp board 12, thereby avoiding the adapter plate 11 occupying the layout space of the light-emitting elements 13, so as to meet the application requirements of the regional backlight display device.

[0041] In some embodiments, multiple light panels 12 are arranged at intervals along a second direction, which intersects with the first direction. The multiple light panels 12 are distributed on opposite sides of the adapter plate 11, or evenly distributed on one side of the adapter plate 11. When arranging the light panels 12, the light panels 12 can be evenly spaced on one side of the adapter plate 11, in which case the adapter plate 11 is located on one side of the light panels 12 relative to the layout of the light panels 12; alternatively, the light panels 12 can be evenly arranged on opposite sides of the adapter plate 11, with the adapter plate 11 located in the middle relative to the layout of the light panels 12.

[0042] In some embodiments, in the second direction, the fourth spacing d between two adjacent first light-emitting elements 131 is the same as the fifth spacing e between two adjacent second light-emitting elements 132. This ensures that the layout of the first light-emitting elements 131 in the adapter plate 11 is consistent with the layout of the second light-emitting elements 132, ensuring the consistency of light output from the light source assembly while fully utilizing the spatial layout of the adapter plate 11.

[0043] In some embodiments, the width of the adapter plate 11 in the first direction is greater than the third spacing c. When multiple rows of first light-emitting elements 131 are arranged on the adapter plate 11, the width of the adapter plate 11 in the first direction is greater than the third spacing c between two first light-emitting elements 131. That is, the minimum structural size of the adapter plate 11 is not limited by the spacing between the light-emitting elements 13, so as to expand the application scenarios of the adapter plate 11.

[0044] Please refer to the following: Figure 5 and Figure 6 In some embodiments, a first connector 121 is provided at one end of the lamp board 12, and a plurality of second connectors 111 are provided at intervals on the side of the adapter plate 11. The adapter plate 11 is connected to the first connector 121 of the corresponding lamp board 12 through the plurality of second connectors 111 to form an electrical connection. In this embodiment, by providing the first connector 121 in the lamp board 12 and the corresponding second connector 111 in the adapter plate 11, the electrical connection between the lamp board 12 and the adapter plate 11 can be directly achieved through the plugging between the first connector 121 and the second connector 111 during assembly, without the need for additional screw structures for assembly, simplifying the assembly process and thus effectively improving assembly efficiency.

[0045] As one embodiment, the first connector 121 has a first width in the first direction that is smaller than the second spacing b, and the second connector 111 has a width in the first direction that is smaller than the second spacing b. In this embodiment, to avoid the connector configuration affecting the configuration of the light-emitting element 13, the widths of the first connector 121 and the second connector 111 can be set to be smaller than the spacing between the light-emitting elements 13.

[0046] Please see Figure 7In some embodiments, the adapter board 11 integrates a driver for driving the light-emitting element 13 to light up. In this embodiment, the adapter board 11 can be directly connected to the motherboard 1 via a signal line, and the light-emitting element 13 is driven to light up according to the control signal output by the motherboard 1. Since the size of the adapter board 11 is increased to accommodate the light-emitting element 13, and the driver can be directly set in the adapter board 11, compared to setting the driver in a separate driver board 2, which drives the light-emitting element 13 through the adapter board 11, the separate driver board 2 can be eliminated, realizing the integrated setup of adapter board 11 for both connection and driving, and simplifying the hardware structure of the display device.
