Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, any modifications made by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be noted that in the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0045] Please refer to Figure 1 and Figure 2, the backlight module 100 provided by the embodiments of the present application includes a support frame 120. A plurality of hole structures K are provided on the side surface of the support frame 120.

[0046] The backlight module 100 provided by the embodiments of the present application includes a support frame 120 with a plurality of hole structures K on its side surface. During the mechanical test, the support frame 120 with the hole structures K is deformed and compressed by force, thereby buffering the display panel disposed thereon, reducing the force intensity on the display panel, and further reducing the probability of display defects in the display module during the mechanical test.

[0047] As Figure 1 shown, the support frame 120 has a side wall 121. The side wall 121 includes a first abutting portion B1, a second abutting portion B2, and a plurality of support bodies T. Among them, the first abutting portion B1 and the second abutting portion B2 are disposed opposite to each other. One end of the support body T is connected to the first abutting portion B1, and the other end of the support body T is connected to the second abutting portion B2. There is a hole structure K between two adjacent support bodies T. In other words, the first abutting portion B1, the second abutting portion B2, and the plurality of support bodies T enclose a plurality of hole structures K.

[0048] The display panel is disposed on the support frame 120 of the backlight module 100 to complete the assembly of the display module. The second abutting portion B2 in the support frame 120 abuts against the display panel, and the support body T provides a supporting force to the display panel through the second abutting portion B2. During the mechanical test, the mechanical impact force is applied along the stacking direction of the display panel and the support frame 120. When the display module is subjected to the mechanical impact force, the support body T provides a supporting force to the display panel. At the same time, due to the setting of the hole structure K, the support frame 120 deforms and compresses in the direction of the mechanical impact force, thereby releasing the mechanical impact force received by the display module and protecting the display panel.

[0049] Optionally, the support frame 120 has at least one side wall 121, and may also have two, three, or four side walls 121. In this embodiment, the support frame 120 has three side walls 121, and the three side walls 121 are connected in sequence. In some other embodiments, the support frame 120 has two side walls 121, and the two side walls 121 are disposed on opposite sides.

[0050] In this embodiment, along the direction intersecting with the extending direction Y1 of the first abutting portion B1, the hole structure K penetrates the side wall 121. On the one hand, the hole structure K penetrating the side wall 121 can further improve the buffering ability of the support frame 120; on the other hand, the hole structure K penetrating the side wall 121 can also make the buffering of the support frame 120 more uniform in the direction of the mechanical impact force.

[0051] As Figure 2As shown, in this embodiment, the support body T is a curved section. The protruding direction of the curved section is parallel to the extension direction Y1 of the first abutting portion B1. It can be understood that the support body T is a curved section. When the support body T is subjected to mechanical impact force, the support body T is more likely to bend and deform, so that the support frame 120 is compressed as the hole structure K is squeezed, thereby slowly releasing the mechanical impact force.

[0052] Optionally, the compression ratio of the support frame 120 is 70% to 95%. For example, the compression ratio of the support frame 120 is 70%, 75%, 80%, 85% or 90%, etc. The compression ratio of the support frame 120 refers to the percentage of the volume of the support frame 120 after compression to the volume of the support frame 120 before compression. It can be understood that the larger the total volume occupied by the hole structure K in the support frame 120, the greater the compressibility of the support frame 120, and the smaller the compression ratio of the support frame 120. The compression ratio of the support frame 120 is also related to the deformation ability of the support body T. The support body T is easier to bend, and the support frame 120 is more easily compressed when subjected to force.

[0053] The compression amount of the support frame 120 is the difference between the size of the support frame 120 before compression and the size of the support frame 120 after compression. In the present application, the direction of application of the mechanical impact force is the stacking direction of the display panel 200 and the support frame 120. That is, the compression amount of the support frame 120 is the difference between the thickness of the support frame 120 before compression and the thickness of the support frame 120 after compression. In the present application, the compression amount of the support frame 120 is between 0.05 and 0.4 millimeters (mm). Optionally, the compression amount is 0.05mm, 0.1mm, 0.2mm, 0.3mm or 0.4mm. Preferably, the compression amount is 0.1 to 0.2mm, such as 0.1mm, 0.12mm, 0.15mm, 0.18mm or 0.2mm, etc. It can be understood that the support frame 120 with a compression amount between 0.1 and 0.2mm has a better buffering capacity and also has a better supporting force to carry the display panel 200.

[0054] Please refer to Figure 3 and Figure 4 . Figure 3 The backlight module 100 provided in the embodiment is Figure 1 The backlight modules 100 provided in the embodiments are substantially the same, except for the specific structure of the support body T.

[0055] like Figure 4 As shown, in this embodiment, the support body T includes a first sub-segment D1 and a second sub-segment D2. One end of the first sub-segment D1 is connected to the first abutting portion B1, the other end of the first sub-segment D1 is connected to one end of the second sub-segment D2, and the other end of the second sub-segment D2 is connected to the second abutting portion B2.

[0056] The first sub-segment D1 is a bent segment, and the second sub-segment D2 is a bent segment. The protruding direction of the first sub-segment D1 is parallel to the extending direction Y1 of the first abutting portion B1, and the protruding direction of the first sub-segment D1 is parallel and opposite to the protruding direction of the second sub-segment D2.

[0057] It can be understood that the first sub-segment D1 and the second sub-segment D2 are connected to form an "S" shape, so that in a mechanical test, when subjected to a mechanical impact force, the support body T is more likely to bend and deform, so that the support frame 120 is compressed.

[0058] Please refer to Figure 5 and Figure 6 . Figure 5 The backlight module 100 provided by the embodiment is substantially the same as Figure 1 the backlight module 100 provided by the embodiment, except for: the specific structure of the support body T.

[0059] As Figure 6 shown, in this embodiment, the support body T includes a first sub-segment D1 and a second sub-segment D2. The first sub-segment D1 extends along a first direction X1. The first direction X1 intersects with the extending direction Y1 of the first abutting portion B1. The second sub-segment D2 extends along a second direction X2. The second direction X2 intersects with the first direction X1 and intersects with the extending direction Y1 of the second abutting portion B2. One end of the first sub-segment D1 is connected to the first abutting portion B1, one end of the second sub-segment D2 is connected to the other end of the first sub-segment D1, and the other end of the second sub-segment D2 is connected to the second abutting portion B2.

[0060] Since the mechanical impact force is along the stacking direction of the display panel 200 and the support frame 120, when the support body T is perpendicular to the second abutting portion B2, the supporting force of the support body T is strong, but the support body T is not easy to bend. In this embodiment, the first sub-segment D1 and the second sub-segment D2 extend in different directions and intersect to form a fold angle, and the first sub-segment D1 and the second sub-segment D2 are respectively connected to the first abutting portion B1 and the second abutting portion B2, so that an acute angle is formed between the first sub-segment D1 and the first abutting portion B1, an acute angle is formed between the second sub-segment D2 and the second abutting portion B2, and the first sub-segment D1 and the second sub-segment D2 are connected to form a fold angle. When a mechanical test is performed, the first sub-segment D1 and the second sub-segment D2 are easily deformed at the fold angle, so that the support frame 120 is compressed, and the mechanical impact force is buffered.

[0061] Please refer to Figure 7 and Figure 8 . Figure 7 The backlight module 100 provided by the embodiment is substantially the same as Figure 1 the backlight module 100 provided by the embodiment, except for: the specific structure of the support body T.

[0062] In this embodiment, the multiple support bodies T include multiple first support bodies T1 and multiple second support bodies T2, as Figure 7 shown.

[0063] As Figure 8 shown, the first support body T1 includes a first sub-segment D1 and a second sub-segment D2. The first sub-segment D1 extends along a first direction X1. The first direction X1 intersects with the extending direction Y1 of the first abutting portion B1. The second sub-segment D2 extends along a second direction X2. The second direction X2 intersects with the first direction X1 and intersects with the extending direction Y1 of the second abutting portion B2. One end of the first sub-segment D1 is connected to the first abutting portion B1, one end of the second sub-segment D2 is connected to the other end of the first sub-segment D1, and the other end of the second sub-segment D2 is connected to the second abutting portion B2.

[0064] The second support body T2 includes a third sub-segment D3 and a fourth sub-segment. The third sub-segment D3 extends along a third direction X3. The third direction X3 intersects with the extending direction Y1 of the first abutting portion B1. The fourth sub-segment extends along a fourth direction X4. The fourth direction X4 intersects with the third direction X3 and intersects with the extending direction Y1 of the second abutting portion B2. One end of the third sub-segment D3 is connected to the first abutting portion B1, one end of the fourth sub-segment is connected to the other end of the third sub-segment D3, and the other end of the fourth sub-segment is connected to the second abutting portion B2.

[0065] It can be understood that a fold angle is formed between the first sub-segment D1 and the second sub-segment D2 in the first support body T1, and a fold angle is formed between the third sub-segment D3 and the fourth sub-segment in the second support body T2. When performing a mechanical test, both the first support body T1 and the second support body T2 are prone to deformation at the fold angle, so that the support frame 120 is compressed to buffer the mechanical impact force.

[0066] In this embodiment, the third direction X3 is parallel to the second direction X2, and the fourth direction X4 is parallel to the first direction X1. Thus, the opening directions of the fold angles formed by the first support body T1 and the second support body T2 are opposite, and the buffering directions of the mechanical impact force when the first support body T1 and the second support body T2 are stressed are different, so that the mechanical impact force can be buffered more evenly. The multiple first support bodies T1 and the multiple second support bodies T2 are alternately arranged in sequence along the extending direction Y1 of the first abutting portion B1, further making the compression of the support frame 120 more uniform and the buffering of the mechanical impact force by the support frame 120 more uniform.

[0067] Please refer to Figure 9 and Figure 10 . Figure 9 The backlight module 100 provided in this embodiment is substantially the same as the Figure 1 backlight module 100 provided in the

[0068] embodiment, except for: the specific structure of the support body T.Figure 10 As shown, in this embodiment, the support body T includes a first sub-segment D1, a second sub-segment D2, and a third sub-segment D3 that are sequentially connected. The first sub-segment D1 is connected between the second sub-segment D2 and the first abutting portion B1, and the third sub-segment D3 is connected between the second sub-segment D2 and the second abutting portion B2. The first sub-segment D1 extends along the first direction X1, the second sub-segment D2 extends along the second direction X2, and the third sub-segment D3 extends along the third direction X3. The second direction X2 intersects with the first direction X1, and the second direction X2 intersects with the third direction X3.

[0069] It can be understood that the first sub-segment D1 and the second sub-segment D2 are connected to form a fold angle, and the second sub-segment D2 and the third sub-segment D3 are connected to form a fold angle. The first sub-segment D1, the second sub-segment D2, and the third sub-segment D3 are connected to form a stepped shape. Since the support body T has two fold angles, in mechanical tests, the support body T is more likely to deform, so that the support frame 120 is compressed to buffer mechanical impact forces.

[0070] Optionally, the extending direction Y1 of the first sub-segment D1 is perpendicular to that of the first abutting portion B1, and the extending direction Y1 of the third sub-segment D3 is perpendicular to that of the second abutting portion B2. Since the first sub-segment D1, the second sub-segment D2, and the third sub-segment D3 are sequentially connected to form two fold angles, the support body T is prone to deformation when subjected to mechanical impact forces. Also, since the first sub-segment D1 is perpendicular to the plane where the first abutting portion B1 is located and the second sub-segment D2 is perpendicular to the second abutting portion B2, the support body T can provide better support force for the display panel 200 disposed on the support frame 120.

[0071] Please refer to Figure 11 , this embodiment of the present application provides a display module 1000. The display module 1000 includes a display panel 200 and the above-mentioned backlight module 100. The backlight module 100 further includes a backplane 110, a reflector 130, a light guide plate 140, and an optical film layer 150. The reflector 130, the light guide plate 140, and the optical film layer 150 are sequentially disposed on the backplane 110. The support frame 120 is disposed outside the light guide plate 140 and the optical film layer 150 and is located above the backplane 110. The first abutting portion D1 of the support frame 120 abuts against the backplane 110. The display panel 200 is disposed on the support frame 120 of the backlight module 100, and the support frame 120 plays a supporting role for the display panel 200. Since a plurality of hole structures K are provided on the side surface of the support frame 120, in mechanical tests, the support frame 120 can also buffer the display panel 200 and reduce the probability of the display panel 200 being damaged by mechanical impact forces.

[0072] Optionally, the display panel 200 is attached to the support frame 120 through an adhesive layer 300 such as a light-shielding adhesive layer or a double-sided foam tape, further strengthening the display panel 200 and the backlight module 100. The second abutting portion D2 of the support frame 120 abuts against the display panel 200 or against the adhesive layer 300, thereby supporting the display panel 200.

[0073] In this embodiment, the display panel 200 is a liquid crystal display panel 200. The liquid crystal display panel 200 includes an array substrate 220, a liquid crystal layer (not shown), and a counter substrate 230. The array substrate 220 and the counter substrate 230 are disposed opposite to each other, and the liquid crystal layer is disposed between the array substrate 220 and the counter substrate 230. The liquid crystal display panel 200 further includes an upper polarizer 240 and a lower polarizer 210. The upper polarizer 240 is disposed on a side of the counter substrate 230 away from the array substrate 220. The lower polarizer 210 is disposed on a side of the array substrate 220 away from the counter substrate 230.

[0074] The above has introduced the backlight module 100 and the display module 1000 provided by the present application in detail.

[0075] The backlight module provided by the embodiment of the present application includes a support frame with a plurality of hole structures on the side. During the mechanical test, the support frame with the hole structure deforms and compresses under force, thereby buffering the display panel disposed thereon, reducing the force intensity of the display panel, and further reducing the probability of display defects in the display module during the mechanical test.

[0076] The principle and implementation manner of the present application have been described above. The description of the above embodiments is only used to help understand the core idea of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
