[0021] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] This application proposes a display module with strong anti-interference, please refer to Figure 1, including a backlight frame 10, a display component 20, a backlight component 30 and a double-sided adhesive layer 31. The display component 20 is bonded and fixed to the backlight component 30 by the double-sided adhesive layer 31. The display component 20 displays the picture, and the backlight component 30 provides a certain brightness illumination for the display component 20 to cooperate with the display component 20 to display a high-quality picture. The backlight frame 10 is made of conductive metal, and a accommodating space is provided inside it for accommodating the display component 20, the backlight component 30 and the double-sided adhesive layer 31. The backlight frame 10 extends at least one hook 32 in the accommodating space, and the hook 32 abuts against the display component 20, so that the interference of the external electrical signal on the display component 20 is guided to the backlight frame 10 through the hook 32, thereby improving the anti-interference performance of the display module, thereby improving the contrast of the display module. Preferably, the display screen 21 is an LCD screen.

[0023] It should be noted that the backlight assembly 30 primarily consists of an LED lamp, a reflective sheet, a light guide plate, an upper light-enhancing plate, a lower light-enhancing plate, and a diffuser. The LED lamp is positioned on the side of the backlight frame 10. The reflective sheet, light guide plate, diffuser plate, lower light-enhancing plate, and upper light-enhancing plate are stacked in sequence and positioned within the housing of the backlight frame 10. The reflective sheet abuts the backlight frame 10. Light emitted by the LED lamp is reflected by the reflective sheet onto the light guide plate, which then passes through the light guide plate, diffuser plate, lower light-enhancing plate, and upper light-enhancing plate in sequence. The light guide plate converts the point light source of the LED lamp into a surface light source for uniform illumination. The upper and lower light-enhancing plates focus the scattered light emitted by the LED lamp toward the front to increase brightness. The diffuser diffuses the light for a more uniform illumination. The reflective sheet also serves to enhance the brightness of the light.

[0024] In one embodiment, see Figure 1 The backlight frame 10 includes a base plate 11 and four baffles 12. The base plate 11 is a rectangular parallelepiped structure. The baffles 12 are arranged around the edges of the base plate 11 to form a storage space. The baffles 12 are perpendicular to the base plate 11 to facilitate the entry of the display unit 20 and the backlight unit 30 into the storage space. The display unit 20 and the backlight unit 30 are rectangular parallelepiped structures, which are compact and reduce space occupation.

[0025] Further, see Figure 1 The hook 32 is provided on the bottom plate 11 to facilitate installation of the display unit 20 and backlight unit 30, allowing the display unit 20 and backlight unit 30 to enter the accommodation space smoothly. The display unit 20 includes a display screen 21, a polarizer, and an ITO metal layer 22. The polarizer is used to filter light. The ITO metal layer 22 is provided between the display screen 21 and the polarizer. The hook 32 abuts the ITO metal layer 22. The edge of the polarizer has an opening to avoid the hook 32 and the ITO metal layer 22.

[0026] In another embodiment, the hook 32 is provided on the baffle 12, and there is no need to open an opening in the polarizer to accommodate the hook 32. The hook 32 on each inner side of the baffle 12 holds the ITO metal layer 22, eliminating the need to open an opening in the polarizer. Furthermore, each baffle 12 is provided with a snap-in interface 33, and each side of the backlight component 30 extends a snap-in block 34 that snaps into the snap-in interface 33. When the backlight component 30 is secured to the backlight frame 10, the snap-in block 34 on the backlight component 30 snaps into the snap-in interface 33 on the backlight frame 10, thereby facilitating the snap-in connection between the backlight component 30 and the backlight frame 10 and improving assembly efficiency. Furthermore, compared to the prior art, the backlight component 30 is screwed onto the backlight frame 10, reducing the thickness of the frame connecting the backlight frame 10 and the backlight component 30. In addition, in order to make the backlight component 30 more firmly fixed on the backlight frame 10, the number of the card interface 33 on each baffle 12 is two, and two card blocks 34 extend from each side of the backlight component 30. Figure 1 The card blocks 34 are respectively engaged with the card interfaces 33, thereby improving the stability of the backlight component 30. The number of card interfaces can be selected according to the weight of the backlight component 30, so as to take into account the firmness and cost of the backlight component 30 and the backlight frame 10.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
