Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a backlight module and a display device. Background Art

[0002] Mini LED has the characteristics of self-luminous display, and its advantages include full solid state, long life, high brightness, low power consumption, small size, ultra-high resolution, and can be used in extreme environments such as high temperature or radiation. Compared with the self-luminous organic light-emitting diode display technology, Mini LED is not only more efficient and has a longer life, but also has relatively stable materials that are not easily affected by the environment, and can also avoid the phenomenon of afterimage. Since the brightness, contrast, life, viewing angle and resolution of display devices with Mini-LED backlight are stronger than traditional liquid crystal display devices and organic light-emitting diode display devices, many manufacturers regard it as the next generation of display technology and begin to actively deploy it.

[0003] Currently, in Mini LED backlight modules, LED lamps are often mounted on circuit boards using surface mount technology (SMT), and solder pads need to be formed on the circuit boards in advance to facilitate subsequent soldering of the LED lamps on the pads.

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0048] Please refer to Figure 1 In the backlight module provided by the related art, a plurality of positive power terminals 1 and a plurality of negative power terminals are included, and one positive power terminal 1 and one negative power terminal 2 form a group, and two lines are connected between each positive power terminal 1 and negative power terminal 2, wherein each line is connected with two soldering pads, and each soldering pad is provided with a positive terminal 3 and a negative terminal 4; at the same time, an LED lamp 5 is welded on each soldering pad, and the positive pole of the LED lamp 5 is connected to the positive terminal 3, and the negative pole is connected to the negative terminal 4, so that four LED lamps can be mounted between a group of positive power terminals 1 and negative power terminals 2. However, when mounting the LED lamp 5, the design of the soldering pads in the backlight module (such as the arrangement direction of the soldering pads, etc.) has been finalized. If a new arrangement of the LED lamp 5 is required, the circuit in the backlight module needs to be redesigned and prepared, which prolongs the process cycle and increases the cost.

[0049] Please refer to Figure 2 and Figure 3 An embodiment of the present invention provides a backlight module, which includes a substrate 101, a power terminal 40, a power line 31, a connecting line 32, and a mounting portion 102.

[0050] Among them, the power terminal 40 and the power trace 31 are arranged on the substrate 101, and the power trace 31 is directly connected to the power terminal 40; the connecting trace 32 is arranged on the substrate 101, and is not directly connected to the power terminal 40; the mounting portion 102 is arranged on the substrate 101, and includes a first terminal 10 and a second terminal 20, and the first terminal 10 is directly connected to the power trace 31, and the second terminal 20 is directly connected to the connecting trace 32, a mounting portion 102 includes a first terminal 10 and at least two second terminals 20 adjacent to the first terminal 10, and / or, a mounting portion 102 includes a second terminal 20 and at least two first terminals 10 adjacent to the second terminal 20.

[0052] It should be noted that the backlight module also includes a light-emitting component 50 connected to the mounting portion 102, a light-emitting component 50 is connected to a first terminal 10 in a mounting portion 102 and one of the second terminals 20 adjacent to the first terminal 10, and / or, a light-emitting component 50 is connected to a second terminal 20 in a mounting portion 102 and one of the first terminals 10 adjacent to the second terminal 20.

[0053] Specifically, please combine Figure 2 , Figure 3 and Figure 4 The backlight module includes a plurality of mounting portions 102 disposed on a substrate 101 , and at least one light-emitting element 50 connected to at least part of the plurality of mounting portions 102 .

[0054] In the embodiment of the present invention, the mounting portion 102 includes at least one first terminal 10 and at least one second terminal 20, and in each mounting portion 102, the first terminal 10 and the second terminal 20 are arranged in at least one of the following two ways.

[0055] In the first type, in one mounting portion 102 , one first terminal 10 is adjacent to one second terminal 20 along a first direction X, and adjacent to another second terminal 20 along a second direction Y, and the first direction X and the second direction Y are different.

[0056] Second, in one mounting portion 102 , one second terminal 20 is adjacent to one first terminal 10 along the first direction X, and is adjacent to another second terminal 20 along the second direction Y.

[0057] In one embodiment, the first direction X is perpendicular to the second direction Y.

[0058] It should be noted that in the same mounting portion 102, adjacent first terminals 10 and second terminals 20 are spaced apart, i.e., short-circuited. When the light-emitting component 50 is connected to the mounting portion 102, a passage is formed between a first terminal 10 and a second terminal 20 connected to the light-emitting component 50 through the light-emitting component 50.

[0059] Preferably, in the same mounting portion 102, the distance between the first terminal 10 and any one of the at least two adjacent second terminals 20 is the first distance, the distance between the second terminal 20 and any one of the at least two adjacent first terminals 10 is the second distance, and the first distance is equal to the second distance.

[0060] In addition, the light-emitting component 50 includes a light-emitting body 53, a positive electrode 51 and a negative electrode 52 located on the side of the light-emitting body 53 close to the mounting portion 102, and the distance between the positive electrode 51 and the negative electrode 52 is equal to the first distance or the second distance, so that the light-emitting component 50 of the same size can select any pair of adjacent first terminals 10 and second single terminals 20 in the mounting portion 102 for connection.

[0061] Furthermore, the power supply terminal 40 includes a first positive power supply terminal 41 and a first negative power supply terminal 42 arranged on the substrate 101; wherein the first terminal 10 includes a first positive terminal 11 connected to the first positive power supply terminal 41 through a power supply line 31, and a first negative terminal 12 connected to the first negative power supply terminal 42 through the power supply line 31, and the second terminal 20 includes a second negative terminal 22 adjacent to the first positive terminal 11 along the first direction X or the second direction Y, and a second positive terminal 21 adjacent to the first negative terminal 12 along the first direction X or the second direction Y.

[0062] Each mounting portion 102 includes a positive terminal (e.g., the first positive terminal 11 or the second positive terminal 21) and a negative terminal (e.g., the first negative terminal 12 or the second negative terminal 22). Thus, between the connected light-emitting element 50 and the mounting portion 102, the positive electrode 51 of the light-emitting element 50 can be connected to the positive terminal through the conductive material 54, and the negative electrode 52 of the light-emitting element 50 can be connected to the negative terminal through the conductive material 54.
