[0022] Display component 100, female buckle 101, backlight component 200, outer frame 201, male buckle 202, sponge body 203, upper soft sponge 204, lower soft sponge 205, light source component 206, backlight panel 207, light guide component 208. Detailed Implementation

[0023] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0024] This application proposes an in-vehicle display module for preventing abnormal noises; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 The backlight assembly includes a sponge body 203, a display component 100, and an outer frame 201 for the backlight assembly 200. A female buckle 101 is provided on the outer side of the display component 100. The backlight assembly 200 is used to illuminate the display component 100 to display an image. The backlight assembly 200 includes an outer frame 201, which is the outer shell of the backlight assembly 200 and is used to protect the backlight assembly 200 and the display component 100. The top of the outer frame 201 is open, and the inside is hollow, that is, the outer frame 201 is U-shaped. A male buckle 202 is provided on the inner side of the outer frame 201. The outer frame 201 is fitted onto the outside of the display component 100. The display component 100 is engaged with the male buckle 202 of the outer frame 201 of the backlight assembly 200 through the female buckle 101, so that the backlight assembly 200 is assembled on the display component 100. The inner wall of the bottom surface of the outer frame 201 is provided with a sponge 203. The sponge 203 itself has a certain elasticity. During the driving process, the sponge 203 can buffer the collision between the display component 100 and the backlight component 200, thereby preventing the display component 100 from contacting the outer frame 201, thus solving the problem of abnormal noise between the display component 100 and the backlight component 200 and improving the user experience.

[0025] Preferably, the thickness of the sponge 203 is 0.20 mm.

[0026] Please see Figure 1 The sponge body 203 includes an upper soft sponge 204 and a lower soft sponge 205, and the outer frame 201 includes a first side and a second side disposed opposite to each other. The upper soft sponge 204 is disposed on the first side and the lower soft sponge 205 is disposed on the second side, reducing the use of sponge and avoiding affecting the heat dissipation of the display component 100. The outer frame 201 is made of iron, which conducts heat quickly.

[0027] Furthermore, there are eight male snap-fits 202 and eight female snap-fits 101. Each male snap-fit ​​202 and each female snap-fit ​​101 is engaged, with eight snap-fit ​​positions, which improves the reliability of the connection between the display assembly 100 and the backlight assembly 200.

[0028] Furthermore, both the display component 100 and the outer frame 201 have a cuboid shape. Two male latches 202 and two female latches 101 form a group, divided into four groups. In each group, the male latches 202 are located on an inner side of the outer frame 201, and in each group, the female latches 101 are located on an outer side of the display component 100. These are respectively located on the four sides of the display component 100 and the outer frame 201, further improving the reliability of the connection between the display component 100 and the backlight component 200.

[0029] In one embodiment, the display assembly 100 includes OCA adhesive, a display, and a cover plate. One side of the display is connected to the cover plate, and the other side is connected to the backlight assembly 200. The cover plate protects the display and is bonded to the display using OCA adhesive. The OCA adhesive is colorless and transparent with a light transmittance of over 90%, exhibiting extremely high light transmittance, thus not affecting the display transmitted through the visible area of ​​the cover plate.

[0030] In the touch display module, after touch, the touch side of the cover is coated with an AF coating, which can prevent fingerprint residue and improve the cleanliness of the touch surface.

[0031] Preferably, the display is an LCD liquid crystal display screen.

[0032] Please see Figure 3 The backlight assembly 200 includes a light source assembly 206, a backlight panel 207, and a light guide assembly 208. The backlight panel 207 is used to fix / limit the light source assembly 206 and the light guide assembly 208. The light source assembly 206 is disposed on the backlight panel 207, and the light guide assembly 208 is disposed on the same side as the light source assembly 206. The light emitted by the light source assembly 206 is guided out through the light guide assembly 208.

[0033] Furthermore, the light guide assembly 208 includes a reflective sheet, a light guide plate, an upper brightness enhancement film, a lower brightness enhancement film, a diffuser film, and a backlight FPC. LED beads are disposed on the side of the backlight plate 207 and are electrically connected to the backlight FPC. The reflective sheet, light guide plate, diffuser film, lower brightness enhancement film, and upper brightness enhancement film are stacked sequentially and disposed within the accommodating space of the backlight plate 207. The reflective sheet abuts against the backlight plate 207, and the light emitted by the LED beads is reflected by the reflective sheet to the light guide plate. The backlight FPC is bent and fixed onto the backlight plate 207. Light passes sequentially through the light guide plate, diffuser film, lower brightness enhancement film, and upper brightness enhancement film. The light guide plate converts the point light source of the LED beads into a surface light source for uniform illumination. The upper and lower brightness enhancement films concentrate the diffused light emitted by the LED beads in the front direction to increase brightness. The diffuser film diffuses the light, making the light more uniformly illuminated, and the reflective sheet enhances the brightness of the light.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
