[0013] Furthermore, the metal protective component also includes a first folded edge, one end of which is connected to the substrate, and the other end of which extends in a direction away from the substrate, wherein a portion of the insulating protective component is connected to the first folded edge and a portion of the substrate.

[0014] Furthermore, the insulating protective member is connected to a surface of the first folded edge away from the back plate, and the insulating protective member is connected to a surface of the substrate away from the side plate.

[0015] Furthermore, the angle formed at the connection between the first folded edge and the substrate is not less than 90°.

[0022] This application provides a display device that includes a metal protective component and an insulating protective component. A portion of the metal protective component is located on the side of the flip-chip film away from the side plate. The insulating protective component is connected to both the metal protective component and the back plate, and a portion of the insulating protective component is located on the side of the driving circuit board away from the display panel. In a top view of the display device, a portion of the insulating protective component overlaps with the driving circuit board. This means that an insulating protective sheet is used to protect the driving circuit board, preventing short circuits even when the insulating protective sheet contacts the driving circuit board, thus reducing the risk of short circuits in the display device.

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0031] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0032] Embodiments of this application provide a display device, with reference to... Figure 2 , Figure 3 , Figure 4 The backlight module 100 includes a backlight module 100, a display panel 200, a driving circuit board 300, a crystal-coated film 400, a metal protective component 500, and an insulating protective component 600. The backlight module 100 includes a back plate 110 and a light strip 120. The back plate 110 includes a base plate 111 and a side plate 112 connected to the base plate 111. The side plate 112 and the base plate 111 are connected to form a receiving cavity 113, and the light strip 120 is disposed within the receiving cavity 113. The display panel 200 is disposed on one side of the backlight module 100. The driving circuit board 300 is disposed on the side of the backlight module 100 away from the display panel 200. The crystal-coated film 400 is disposed on the outside of the receiving cavity 113. A portion of the flip-chip film 400 is located on the side of the side panel 112 away from the LED strip 120. One end of the flip-chip film 400 is electrically connected to the driving circuit board 300, and the other end of the flip-chip film 400 is electrically connected to the display panel 200. A portion of the metal protective member 500 is located on the side of the flip-chip film 400 away from the side panel 112. The insulating protective member 600 is connected to both the metal protective member 500 and the back panel 110, and a portion of the insulating protective member 600 is located on the side of the driving circuit board 300 away from the display panel 200. In a top view of the display device, a portion of the insulating protective member 600 overlaps with the driving circuit board 300.

[0033] refer to Figure 1Conventional display devices use a metal protective plate 201 to protect the driving circuit board 101. However, the metal protective plate 201 is prone to contact with the driving circuit board 101, which can easily cause a short circuit in the display device. Therefore, the technical solution of this application includes a metal protective component 500 and an insulating protective component 600 in the display device. A portion of the metal protective component 500 is located on the side of the flip-chip film 400 away from the side plate 112. The insulating protective component 600 is connected to both the metal protective component 500 and the back plate 110, and a portion of the insulating protective component 600 is located on the side of the driving circuit board 300 away from the display panel 200. In the top view of the display device, a portion of the insulating protective component 600 overlaps with the driving circuit board 300. That is, an insulating protective sheet is used to protect the driving circuit board 300, which is a good feature of the insulating protective sheet. Contact with the driver circuit board 300 will not cause a short circuit in the driver circuit board 300, thereby reducing the risk of a short circuit in the display device. Furthermore, since the combination of the metal protective component 500 and the insulating protective component 600 protects the flip-chip, including the flip-chip film 400 on the side mainly protected by the driver circuit board 300, and the flip-chip film 400 on the side away from the base plate 111 protected by the metal protective component 500, compared to the conventional solution that uses the metal protective component 500 to protect both the flip-chip film 400 and the driver circuit board 300, the material used for the metal protective component 500 can be saved, thereby reducing the cost of the display device.

[0034] In this embodiment, the light strip 120 is fixed to the side plate 112.

[0035] In this embodiment, reference Figure 3 The backlight module 100 also includes a light guide 130, which is disposed on the base plate 111, wherein the light emitting side of the lamp strip 120 faces the light incident surface of the light guide 130.

[0036] In this embodiment, reference Figure 3 The backlight module 100 further includes a reflector 140, which is located between the base plate 111 and the light guide 130.

[0037] In this embodiment, reference Figure 3 The backlight module 100 further includes an optical film 150, which is disposed on a surface of the light guide 130 away from the base plate 111.

[0038] In this embodiment, reference Figure 3 The metal protective component 500 includes a substrate 510, which is located on the side of the flip-chip film 400 away from the side plate 112, and a portion of the insulating protective component 600 is connected to the substrate 510.

[0039] In this embodiment, reference Figure 3 The metal protective member 500 further includes a first folded edge 520, one end of which is connected to the substrate 510, and the other end of which extends in a direction away from the substrate 510. A portion of the insulating protective member 600 is connected to both the first folded edge 520 and a portion of the substrate 510. By including the first folded edge 520 in the metal protective member 500, with one end connected to the substrate 510 and the other end extending in a direction away from the substrate 510, and a portion of the insulating protective member 600 connected to both the first folded edge 520 and a portion of the substrate 510, the contact area of ​​the insulating protective member 600 can be increased, thereby improving the stability of the connection between the insulating protective member 600 and the metal protective member 500.

[0040] In this embodiment, reference Figure 3 The insulating protective member 600 is connected to the surface of the first folded edge 520 away from the back plate 110, and the insulating protective member 600 is connected to the surface of the substrate 510 away from the side plate 112. By connecting the insulating protective member 600 to the surface of the first folded edge 520 away from the back plate 110 and to the surface of the substrate 510 away from the side plate 112, compared to connecting the insulating protective member 600 to the surface of the first folded edge 520 near the back plate 110 and to the surface of the substrate 510 near the side plate 112, it is easier to connect and fix the insulating protective member 600 to the metal protective member 500, reducing the assembly difficulty of the display device.

[0041] In this embodiment, reference Figure 3 The included angle α formed at the connection between the first folded edge 520 and the substrate 510 is not less than 90°.

[0042] In this embodiment, the included angle α formed at the connection between the first folded edge 520 and the substrate 510 is 90°.

[0043] In this embodiment, the included angle α formed at the connection between the first folded edge 520 and the substrate 510 is greater than 90°. By setting the included angle α formed at the connection between the first folded edge 520 and the substrate 510 to be greater than 90°, the connection between the first folded edge 520 and the substrate 510 can be smoother, which can avoid the risk of the insulating protective member 600 breaking at the connection between the first folded edge 520 and the substrate 510 due to the first folded edge 520 being too sharp.

[0044] In this embodiment, reference Figure 3 In the top view of the display device, the edge S1 of the first folded edge 520 on the side away from the substrate 510 does not exceed the edge S2 of the display panel 200 on the side close to the substrate 510. When the first folded edge 520 is too long and a portion of the first folded edge 520 detaches from the insulating protective member 600, the edge of the first folded edge 520 is prone to contacting and scratching the flip-chip film 400, leading to breakage of the flip-chip film 400. Therefore, by setting the edge S1 of the first folded edge 520 on the side away from the substrate 510 to not exceed the edge S2 of the display panel 200 on the side close to the substrate 510, the stability of the connection between the insulating protective member 600 and the metal protective member 500 can be improved, and the edge of the first folded edge 520 can be prevented from contacting and scratching the flip-chip film 400, thereby reducing the risk of breakage of the flip-chip film 400.

[0045] In this embodiment, reference Figure 4 The display device further includes a frame 700 and a connector 800. The frame 700 is connected to the side plate 112, and one end of the connector 800 passes through the substrate 510 and is connected to the side plate 112.

[0046] In this embodiment, reference Figure 3 The display panel 200 is disposed on the frame 700.

[0047] In this embodiment, reference Figure 4 The connector 800 is a connecting screw, and the side plate 112 has a screw hole 1121. A portion of the connecting screw passes through the substrate 510 and connects to the screw hole 1121. By setting the connector 800 to a connecting screw, and the side plate 112 having a screw hole 1121, the metal protective plate is fixed to the side plate 112 using a screw connection method. This eliminates the need for a complex structure to fix the metal protective plate, reducing costs and improving the production efficiency of the display device.

[0048] In this embodiment, reference Figure 4The metal protective component 500 further includes a second folded edge 530. One end of the second folded edge 530 is connected to the substrate 510, and the other end of the second folded edge 530 extends in a direction away from the substrate 510. A surface of the second folded edge 530 near the back plate 110 contacts a surface of the frame 700 away from the back plate 110. By including the second folded edge 530 in the metal protective component 500, with one end connected to the substrate 510 and the other end extending in a direction away from the substrate 510, and a surface of the second folded edge 530 near the back plate 110 contacting a surface of the frame 700 away from the back plate 110, the frame 700 can provide support for the metal protective component 500. This facilitates alignment of the metal protective component 500 with the side plate 112 during installation, thereby reducing the difficulty of assembling the display device.

[0049] In this embodiment, reference Figure 4 The substrate 510 has a recessed portion 511 on the side away from the side plate 112. The connector 800 includes a base 810 and an extension 820 connected to the base 810. The extension 820 passes through the substrate 510 and is connected to the side plate 112. The base 810 is located in the recessed portion 511, and the depth of the recessed portion 511 is greater than the thickness of the base 810. By providing a recessed portion 511 on the surface of the substrate 510 away from the side plate 112, the connector 800 includes a base 810 and an extension 820 connected to the base 810. The extension 820 passes through the substrate 510 and connects to the side plate 112. The base 810 is located within the recessed portion 511, and the depth of the recessed portion 511 is greater than the thickness of the base 810. This hidden design of the connector 800 prevents it from contacting the side wall of the display device's casing (not shown in the figure), thereby reducing the risk of light leakage from the display device.

[0050] In this embodiment, the substrate 510 is further provided with an opening, through which the extension 820 passes.

[0051] In this embodiment, a surface of the base 810 near the side plate 112 is in contact with a surface of the metal protective plate away from the side plate 112.

All such modifications and improvements fall within the scope of protection defined by the claims of this application.
