In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0052] Embodiment 1

[0053] Embodiment 1 of the present application provides a backlight module 100, which includes a light-emitting component 110. The light-emitting component 110 includes a light board and a plurality of light-emitting elements arranged on the light board. The light-emitting element may be a light-emitting diode (LED), a sub-millimeter light-emitting diode (Mini LED), a micro light-emitting diode (Micro LED) or other types of self-luminous devices, and may be specifically configured according to actual needs.

[0054] In the examples of this application, see Figure 1 As shown, the backlight module 100 further includes a back frame assembly 120 . The back frame assembly 120 includes a back plate 121 . The back plate 121 is provided with a receiving cavity 1210 and a connecting portion 1211 .

[0055] The accommodating cavity 1210 is a rectangular groove structure, and groove structures of other shapes may also be used, such as square or circular groove structures. The accommodating cavity 1210 is used to place the light-emitting component 110, and the light-emitting component 110 is directly fixed in the accommodating cavity 1210. The area of ​​the accommodating cavity 1210 is larger than the area of ​​the light board, so that the light board can be placed in the accommodating cavity 1210 more easily. However, the area of ​​the accommodating cavity 1210 should not be too large and the depth of the accommodating cavity 1210 should be greater than the height of the light-emitting component 110, so as to limit the position of the light-emitting component 110 in the accommodating cavity 1210 and avoid the light-emitting component 110 from moving during transportation.

[0056] The connecting portion 1211 is disposed above the accommodating cavity 1210 and is connected to the accommodating cavity 1210. The connecting portion 1211 is used to connect to the display panel 200.

[0057] Among them, in the examples of this application, see Figure 2 and Figure 3 As shown, this backlight module 100 is a curved backlight module 100, that is, the back plate 121, the display panel 200 and the light board are all curved parts, and the sides of the back plate 121, the display panel 200 and the light board are bent inward. When the display panel 200 is arranged on the connecting portion 1211, in the direction from the display panel 200 to the back frame assembly 120, the display panel 200 can completely block the back frame assembly 120. In other words, from the user's front viewing angle, the display panel 200 can completely block the back frame assembly 120 to achieve a borderless design; that is, the display device 10 formed by using this backlight module 100 is a curved borderless display device 10.

[0058] It should be noted that this backlight module 100 is a direct-type backlight module 100, that is, the light-emitting element emits light from the bottom of the back plate 121 and is injected from the bottom of the display panel 200. The display panel 200 includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The deflection angle of the liquid crystal molecules in the liquid crystal layer is controlled by controlling the voltage on the first substrate and the second substrate. When light is injected from the bottom of the display panel 200, that is, when it is injected from the side of the first substrate away from the liquid crystal layer, the light passes through the first substrate, the liquid crystal molecules, and the second substrate in sequence to be emitted, thereby completing the display, and the emission angle of the light is controlled by the deflection angle of the liquid crystal molecules.

[0059] It is worth mentioning that the back plate 121 can be an integrally stamped metal back plate 121 .

[0060] It can be understood that the present application eliminates the rubber frame supporting structure between the display panel 200 and the back plate 121, and directly connects the display panel 200 to the connecting portion 1211 of the back plate 121, thereby reducing the weight and thickness of the entire display device 10, and can better realize the lightweight and thinness of the display device 10; in addition, the use of the rubber frame is reduced, and the assembly efficiency of the whole machine can be effectively improved, and the effect of reducing plastic and carbon can be played.

[0061] In order to improve the connection tightness between the display panel 200 and the back plate 121, see Figure 1 and Figure 4 As shown, the backlight module 100 also includes an adhesive member 130, which can be a double-sided adhesive foam. One side of the adhesive member 130 is adhered to the plane of the connecting portion 1211 of the back panel 121, and the other side is adhered to the side of the display panel 200 close to the back panel 121, so that the display panel 200 is firmly fixed on the connecting portion 1211 of the back panel 121, that is, the display panel 200 and the connecting portion 1211 of the back panel 121 are firmly fixed.

[0062] In the examples of this application, see Figure 1 and Figure 4 As shown, the back plate 121 is a rectangular structure, which includes upper and lower sides and left and right sides, that is, the back plate 121 has four sides, that is, the back plate 121 has four connecting parts 1211, which are respectively located at the upper and lower sides of the back plate 121 and the left and right sides of the back plate 121. In order to ensure the pasting effect, the pasting member 130 should be provided on both the upper and lower sides and the left and right sides of the back plate 121, that is, the pasting member 130 is provided on the planes of the four connecting parts 1211, so that the display panel 200 can be firmly fixed on the back plate 121.

[0063] In addition, the adhesive effect of the adhesive member 130 should be greater than the bending stress of the display panel 200 to prevent the display panel 200 and the back plate 121 from being separated from each other.

[0064] In the examples of this application, see Figure 1 and Figure 6 As shown, the backlight module 100 also includes an optical component 140, which is arranged on the side of the light-emitting component 110 away from the back panel 121. The optical component 140 includes a diffusion plate and a brightness enhancement film arranged in sequence. The diffusion plate is arranged on the side of the brightness enhancement film close to the light-emitting element. The diffusion plate can fully diffuse the light emitted by the light-emitting element so that the light is evenly irradiated to the display panel 200, making the display more uniform; the brightness enhancement film can brighten the light.

[0065] See also Figure 1 and Figure 6 As shown, the back panel 121 is also provided with a accommodating cavity 1212, and the accommodating cavity 1212 is located on the side of the accommodating cavity 1210 close to the display panel 200, and the optical component 140 is carried on the bottom wall of this accommodating cavity 1212, and the bottom wall of the accommodating cavity 1212 is connected to the side wall of the accommodating cavity 1210, and the side wall of the accommodating cavity 1212 is connected to the connecting part 1211, that is, the connecting part 1211 is connected to the accommodating cavity 1210 through the accommodating cavity 1212.

[0066] It should be noted that see Figure 1 As shown, the accommodating cavity 1212 is a rectangular structure, and the accommodating cavity 1212 and the accommodating cavity 1210 are located at different heights, so that a step structure is formed between the accommodating cavity 1212 and the accommodating cavity 1210, and the area of ​​the accommodating cavity 1212 is larger than the area of ​​the accommodating cavity 1210, and the back plate 121 is a metal back plate 121 that is opaque. When the optical component 140 is placed on the bottom wall of the accommodating cavity 1212, the area of ​​the optical component 140 is larger than the area of ​​the light-emitting component 110, so that the light emitted by the light-emitting element is absorbed by the diffuser, and no light leakage or other problems occur, and the light emitted by the light-emitting element is fully utilized.

[0067] In addition, see Figure 6 As shown, the depth of the accommodating cavity 1212 is greater than the height of the optical component 140, and the area of ​​the accommodating cavity 1212 is greater than the area of ​​the optical component 140, so that the optical component 140 can be placed in the accommodating cavity 1212 more easily, and the optical component 140 can be restricted by the accommodating cavity 1212 to avoid displacement during transportation.

[0068] In the examples of this application, see Figure 6As shown, the bottom wall of the accommodating cavity 1212 and the side wall of the accommodating cavity 1212 are connected in an arc shape, so as to avoid the problem of damage caused by collision between the optical component 140 and the connection between the side wall of the accommodating cavity 1212 and the bottom wall of the accommodating cavity 1212, thereby ensuring the optical effect of the optical component 140.

[0069] In the examples of this application, see Figure 4 , Figure 6 and Figure 7 As shown, the back panel 121 includes a first side panel 1213, a second side panel 1214, a third side panel 1215 and a fourth side panel 1216. The first side panel 1213 and the third side panel 1215 are arranged opposite to each other, and the second side panel 1214 and the fourth side panel 1216 are arranged opposite to each other, and from the perspective of the user viewing the display panel 200, the first side panel 1213 and the third side panel 1215 are located on the left and right sides of the back panel 121, and the second side panel 1214 and the fourth side panel 1216 are located on the top and bottom sides of the back panel 121; that is, the opposite ends of the first side panel 1213 are connected to the third side panel 1215 through the second side panel 1214 and the fourth side panel 1216, respectively.

[0070] The first side plate 1213 , the second side plate 1214 , the third side plate 1215 and the fourth side plate 1216 are all extended toward a side away from the display panel 200 .

[0071] In the embodiment of the present application, the display panel 200 is electrically connected to the circuit board 300 to control the voltage on the first substrate and the second substrate to control the deflection angle of the liquid crystal molecules. The circuit board 300 may be a printed circuit board 300 (PCB). The circuit board 300 may be arranged on the back side of the back plate 121, that is, the circuit board 300 is located on the side of the back plate 121 away from the light-emitting component 110. The circuit board 300 and the display panel 200 may be connected via a flexible circuit board 400, which is arranged in a U shape and has good bending performance, so that the circuit board 300 and the display panel 200 can be easily electrically connected.

[0072] See also Figure 7 As shown, in order to prevent the fourth side panel 1216 of the back panel 121 from scratching the flexible printed circuit 400 (Flexible Printed Circuit, FPC) or the chip on flex (Chip On Flex, COF), the fourth side panel 1216 includes a main body and a bending portion bent away from the circuit board 300, the bending portion is warped toward one side of the display panel 200, and the connection between the bending portion and the main body is an arc structure, so as to further prevent the fourth side panel 1216 from scratching the flexible printed circuit 400 or the chip on flex.

[0073] In the examples of this application, see Figure 4 As shown, the first side panel 1213 and the third side panel 1215 form a first angle α1 with the connecting portion 1211, and the first angle α1 is less than 90°, for example, 75°, 80°, 85°, etc., that is, the bending angle of the first side panel 1213 and the third side panel 1215 is greater than 90°, so as to ensure that the back frame assembly 120 on the back is not visible from the viewing angle, so as to realize a curved borderless design.

[0074] See also Figure 6 As shown, the second side plate 1214 and the connecting portion 1211 form a second angle α2, and the second angle α2 is 90°, that is, the bending angle of the second side plate 1214 is 90°, so as to facilitate the operation of the bending machine and facilitate assembly and fixation.

[0075] See also Figure 7 As shown, the fourth side panel 1216 and the connecting portion 1211 form a third angle α3, and the value range of the third angle α2 is 80° to 90°, that is, the bending angle of the fourth side panel 1216 is 90° to 100° to avoid the bent part scratching the structure of the flexible circuit board 400 and the flip chip film.

[0076] In the examples of this application, see Figure 1 and Figure 3 As shown, the back frame assembly 120 also includes a rear shell 122, which includes a first side 1220, a second side 1221, a third side 1222 and a fourth side 1223, the first side 1220 and the third side 1222 are arranged opposite to each other, the second side 1221 and the fourth side 1223 are arranged opposite to each other, and the opposite ends of the first side 1220 are respectively connected to the third side 1222 through the second side 1221 and the fourth side 1223; and the first side 1220, the second side 1221, the third side 1222 and the fourth side 1223 respectively correspond to the first side plate 1213, the second side plate 1214, the third side plate 1215 and the fourth side plate 1216 of the back plate 121, and the fourth side 1223 is fixedly connected to the fourth side plate 1216.

[0077] See also Figure 2 , Figure 5 and Figure 7As shown, the display device 10 further includes a face frame press strip 500, which is disposed at the bottom of the display panel 200, and the face frame press strip 500 includes a pressing portion 510 and an abutting portion 520 connected to each other, and the pressing portion 510 is disposed on a side of the display panel 200 away from the back plate 121 to press the bottom side of the display panel 200. The abutting portion 520 is extended toward the side away from the display panel 200, and a right angle is formed between the abutting portion 520 and the pressing portion 510, that is, the abutting portion 520 is perpendicular to the pressing portion 510, and the abutting portion 520 and the flexible circuit board 400 are both disposed between the fourth side 1223 of the rear shell 122 and the fourth side plate 1216 of the back plate 121, and the face frame press strip 500, the rear shell 122 and the back plate 121 are fixed by using a countersunk screw structure.

[0078] It is understandable that the length of the pressing portion 510 is the same as the length of the display panel 200 , and is designed according to the curvature of the display panel 200 .

[0079] In the examples of this application, see Figure 4 and Figure 6 As shown, a first mounting position 1217 is formed between the first side plate 1213, the connecting portion 1211, and the outer wall of the accommodating cavity 1212; a second mounting position 1218 is formed between the second side plate 1214, the connecting portion 1211, and the outer wall of the accommodating cavity 1212; and a third mounting position 1219 is formed between the third side plate 1215, the connecting portion 1211, and the outer wall of the accommodating cavity 1212. The first side 1220 of the rear shell 122 is inserted into the first mounting position 1217, the second side 1221 of the rear shell 122 is inserted into the second mounting position 1218, and the third side 1222 of the rear shell 122 is inserted into the third mounting position 1219. When the first side 1220, the second side 1221 and the third side 1222 of the rear shell 122 are respectively inserted into the first mounting position 1217, the second mounting position 1218 and the third mounting position 1219, the first side 1220 is fixed to the first mounting position 1217, the second side 1221 is fixed to the second mounting position 1218, and the third side 1222 is fixed to the third mounting position 1219 by using a snap or screw structure, so as to fix the rear shell 122 to the back panel 121.

[0080] It can be understood that the first side 1220, the second side 1221, the third side 1222 and the fourth side 1223 of the rear shell 122 are designed accordingly according to the bending angles of the first side panel 1213, the second side panel 1214, the third side panel 1215 and the fourth side panel 1216 of the back panel 121.

[0081] In addition, when the rear shell 122 is locked in the installation position of the back plate 121 , the assembly efficiency of the rear shell 122 and the back plate 121 is saved, thereby improving the overall assembly efficiency.

[0082] It is worth mentioning that Figure 1 As shown, the display device 10 further includes a support base 600 , which is disposed on a side of the rear housing 122 away from the back plate 121 , and is used to be placed on a table to support the entire backlight module 100 and the display panel 200 .

[0083] The assembly process for this application is:
