DETAILED DESCRIPTION

[0077] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] In the drawings, the size of the constituent elements, the thickness of the layer or the area may be exaggerated for the sake of clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the size shown in the drawings, and the shapes and sizes of the components in the drawings do not reflect the true proportions. In addition, the drawings schematically show ideal examples, and any implementation of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0079] At present, liquid crystal display devices, as display components of electronic devices, have been widely used in electronic products in various scenarios due to their advantages of low power consumption, miniaturization, lightness, etc. Existing liquid crystal display devices include a liquid crystal display panel (LCD) and a backlight module that provides stable, high-brightness and uniformly distributed light for the display panel.

[0080] With the development of display technology, in specific application scenarios, the requirements for the picture quality of display devices are getting higher and higher. In medical scenarios, foreign matter may enter the backlight module through the gaps or holes in the back panel, thereby reducing the uniformity of the brightness and color uniformity of the display device. Among them, the rubber frame limiting structure fixes the display panel by forming a protruding structure on the rubber frame, and because the protruding structure of the rubber frame itself is part of the rubber frame, it will scratch the rubber frame when the display panel is placed, thereby generating rubber frame debris and foreign matter. The generated rubber frame debris and foreign matter will therefore enter the structure of the backlight module and the display panel, causing adverse effects on the display effect of the display module.

[0081] In view of this, an embodiment of the present application provides a display module. Figure 1 FIG. 1 shows an exploded schematic diagram of a display module proposed in an embodiment of the present application. Figure 2 FIG. 1 shows a top view of a display module proposed in an embodiment of the present application. Figure 3 FIG. 1 shows a partially enlarged schematic diagram of an elastic structure of a rubber frame proposed in an embodiment of the present application, such as Figure 1-Figure 3 As shown, the display module includes a display panel 1 and a backlight module, the backlight module is arranged on the side of the display panel 1 away from the display surface, and the backlight module includes: a back plate 5, the back plate 5 includes a bottom plate and side plates surrounding the bottom plate; a rubber frame 3, the rubber frame 3 is arranged on the side of the back plate 5 close to the display surface.

[0082] In the embodiment of the present application, the plastic frame 3 includes a main body 301 enclosing the display panel 1 and a limiting portion 302, wherein the limiting portion 302 is disposed on a side of the main body 301 away from the bottom plate and connected to the main body 301. In some embodiments, the side wall of the limiting portion 302 close to the display panel 1 is disposed away from the display panel 1 relative to the side wall of the main body 301 close to the display panel 1, and the main body 301 and the limiting portion 302 form a step-like structure.

[0083] In the embodiment of the present application, the side wall of the limiting portion 302 close to the display panel 1 is provided with a first positioning groove 303, and the first positioning groove 303 is recessed toward the side away from the display panel 1. The first positioning groove 303 is used to avoid the display panel 1, and prevent the display panel 1 from colliding or scratching with the limiting portion 302 when it is set in the plastic frame 3, thereby effectively avoiding the generation of foreign matter due to scratching the plastic frame 3. On the other hand, in order to effectively limit the display panel 1 placed in the plastic frame 3, the first positioning groove 303 is also used to accommodate the elastic structure 31.

[0084] In the embodiment of the present application, the backlight module further includes an elastic structure 31, the elastic structure 31 is at least partially located in the first positioning groove 303, the elastic structure 31 is protruded toward the display panel 1 relative to the side wall of the limiting portion 302 close to the display panel 1, and the elastic structure 31 can be deformed toward the first positioning groove 303. By setting the elastic structure 31 to protrude toward the display panel 1 relative to the inner side wall of the limiting portion 302, the plastic frame 3 is used to limit and fix the display panel 1 through the elastic structure 31 located in the first positioning groove 303. At the same time, due to the provision of the elastic structure 31, the display panel 1 is in direct contact with the elastic structure 31, avoiding hard contact with the limiting portion 302 of the plastic frame 3. When the display panel 1 squeezes or collides with the elastic structure 31, the elastic structure 31 is deformed toward the first positioning groove 303 to buffer the movement of the display panel 1, so that the force on the display panel 1 is uniform.

[0085] In some optional embodiments, the elastic structure 31 is a limit block. For example, the limit block can be a rectangular limit block; the size of the rectangular limit block includes but is not limited to 9mm×2mm×2mm, 25mm×2mm×2mm, 50mm×2mm×2mm, wherein the longer side of the rectangular limit block is the size along the first direction, such as Figure 3 As shown, the first direction X is the extending direction of the side wall of the limiting portion 303 close to the display panel 1 .

[0086] In some optional implementations, the material of the elastic structure 31 is a material with elastic deformation ability. Optionally, the material of the elastic structure 31 is a silicone material or the like.

[0087] In some optional implementations, the elastic structure 31 is embedded in the first positioning groove 303 . The first positioning groove 303 includes a first opening close to the display panel 1, and the size of the groove bottom of the first positioning groove 303 along the first direction is larger than the size of the first opening along the first direction; the elastic structure 31 fills the internal space of the first positioning groove 303 and extends out of the first positioning groove 303 through the first opening, and the elastic structure 31 is offset against the first opening so that the elastic structure 31 and the first positioning groove 303 are interference-fitted. In the embodiment of the present application, since the size of the elastic structure 31 along the first direction is slightly larger than the size of the first opening along the first direction, after the elastic structure 31 is filled into the first positioning groove 303 through the first opening, the position where the elastic structure 31 contacts the first opening is squeezed by the first opening with a smaller size and undergoes local compression deformation, so that the size of the elastic structure 31 along the first direction X is adapted to the size of the first opening by elastic deformation, so that the elastic structure 31 is offset against the first opening, and the first opening prevents the elastic structure 31 from restoring its deformation, so that the elastic structure 31 and the first positioning groove 303 are interference-fitted, and the first positioning groove 303 and the elastic structure 31 are snap-fitted and fixed.

[0088] Optionally, the dimension of the first positioning groove 303 along the first direction gradually decreases from the first opening to the groove bottom of the first positioning groove 303. Exemplarily, the first positioning groove 303 is a trapezoidal groove with the first opening as the shorter bottom side.

[0089] In some optional embodiments, an adhesive layer is provided between the elastic structure 31 and the bottom of the first positioning groove 303, and the elastic structure 31 and the bottom of the first positioning groove 303 are fixedly connected by the adhesive layer. For example, the adhesive layer can be a double-sided adhesive tape. By providing the adhesive layer to fix the elastic structure 31 and the bottom of the first positioning groove 303, when the display panel 1 moves and squeezes the elastic structure 31, the elastic structure 31 is forced to deform toward the bottom of the first positioning groove 303, thereby further strengthening the fixing effect of the adhesive layer between the bottom of the first positioning groove 303 and the elastic structure 31, and effectively preventing the elastic structure 31 from detaching from the first positioning groove 303.

[0090] In some optional embodiments, Figure 4 FIG. 4 shows a schematic diagram of the distribution of the first positioning grooves of a plastic frame proposed in an embodiment of the present application. Figure 4As shown, the plastic frame 3 includes a plurality of side frames arranged around the display panel 1, and the first positioning grooves 303 are arranged at both ends of each side frame. In the embodiment of the present application, the first positioning grooves 303 are arranged at both ends of each side frame, so that the first positioning grooves 303 and the elastic structure 31 arranged corresponding to the first positioning grooves 303 can protect the angular position of the display panel 1, prevent the display panel 1 from having a hard contact with the plastic frame 3 at the weakest angular position, and effectively limit the position of the display panel 1, so that the display panel 1 is evenly stressed. Optionally, on each side frame, the distance from the first positioning groove 303 to the corresponding end face of the side frame is 20 mm.

[0091] In some optional embodiments, in order to prevent the display panel 1 from squeezing the center of the side frame, a first positioning groove 303 is provided at the center of at least one side frame. In some embodiments, the display module is placed vertically in use, so the squeezing of the center of the side frame by the display panel 1 mainly acts on the side frame located at the lower side (or ground side) of the display module. Therefore, at least the first positioning groove 303 is provided at the center of the side frame located at the lower side of the display module. The elastic structure 31 in the first positioning groove 303 at the center of the side frame on the ground side buffers the squeezing of the side frame on the ground side by the display panel 1 due to its own gravity.

[0092] Exemplarily, the rubber frame 3 is a rectangular rubber frame, and the two side frames corresponding to each corner position of the rubber frame are both provided with the first positioning groove 303 near the corner position; at the same time, a first positioning groove 303 is provided at the center position of the side frame on the ground side.

[0093] In some optional embodiments, Figure 5 A schematic side view of a front frame according to an embodiment of the present application is shown. Figure 6 FIG. 1 shows a partial enlarged schematic diagram of a plastic frame and a front frame proposed in an embodiment of the present application, such as Figure 5 and Figure 6 As shown, the display module further includes a front frame 2, and the front frame 2 is fixed to the back plate 5 by fasteners (such as screws). In order to hide the fasteners located on the side wall of the front frame 2 and prevent the fasteners from exceeding the outer contour of the display module, a convex structure 22 is provided on the side wall of the front frame 2, and the convex structure 22 includes a convex surface 221 protruding toward one side of the display panel 1. The front frame 2 is fixedly connected to the side plate of the back plate 5 through the convex surface 221 of the convex structure 22. In the embodiment of the present application, by providing the convex structure 22, the fasteners fixedly connecting the back plate 5 and the front frame 2 are arranged in the convex structure 22, so that the fasteners are shielded by the structure of the convex structure 22 close to the display surface.

[0094] When the front frame 2 and the plastic frame 3 are assembled, the front frame 2 needs to be buckled on the side of the plastic frame 3 close to the display surface, and since the convex structure protrudes toward the side of the display panel 1, the convex structure 22 is closer to the plastic frame side wall of the plastic frame 3 than other structures on the side wall of the front frame 2. In the process of buckling down, the convex structure 22 will scratch the plastic frame 3, so that plastic frame debris and foreign matter enter the interior of the display module, affecting the quality of the display image. Therefore, in the embodiment of the present application, Figure 7 A schematic front view of a cross section of a first avoidance groove of a plastic frame along CC' is shown in one embodiment of the present application. Figure 8 FIG. 4 shows a schematic cross-sectional side view of a first avoidance groove of a plastic frame along line CC' proposed in an embodiment of the present application. Figure 7 and Figure 8 As shown, the side wall of the limiting portion 302 away from the display panel 1 is provided with a first avoidance groove 304, and the first avoidance groove 304 is provided corresponding to the convex hull structure 22 of the front frame 2. Specifically, the first avoidance groove 304 includes: a first side surface 3041, the first side surface 3041 is provided close to the display panel 1 relative to the second side surface 3042, and the second side surface 3042 is the side surface of the plastic frame 3 away from the display panel 1; a connecting plane 3043, the connecting plane 3043 connects the first side surface 3041 and the second side surface 3042, and the position where the first side surface 3041 is connected to the connecting plane 3043 and the position where the second side surface 3042 is connected to the connecting plane 3043 form a step.

[0095] Optionally, in the orthographic projection on the first plane, the convex surface 221 is located between the first side surface 3041 and the second side surface 3042, and the first plane is a horizontal plane where the display panel 1 is located. In the embodiment of the present application, since the first side surface 3041 is closer to the display panel 1 than the second side surface 3042, and the convex surface 221 is located between the first side surface 3041 and the second side surface 3042 in the horizontal direction, when the front frame 2 is pressed downward for assembly, the convex surface 221 of the convex hull structure 22 can move downward through the space between the first side surface 3041 and the second side surface 3042, avoiding hard contact with the plastic frame 3, thereby preventing the generation of plastic frame debris and foreign matter.

[0096] In some optional embodiments, a chamfer structure 3044 is formed at the step where the second side surface 3042 is connected to the connecting plane 3043. For example, the chamfer structure 3044 is a C-shaped chamfer structure or an R-shaped chamfer structure. After the convex structure 22 of the front frame 2 passes through the space on the side of the first side surface 3041 away from the display panel 1, the convex structure 22 undergoes elastic deformation toward the side away from the display panel 1, and moves along the step where the second side surface 3042 is connected to the connecting plane 3043 to the second side surface 3042, and finally passes through the second side surface 3042 and engages with the second avoidance groove 305 provided on the side wall of the plastic frame 3 to complete the buckling assembly.
