The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a front view of a display device according to an embodiment of the present application; FIG. 2 is a rear view of the display device of FIG. 1; fig. 3 is a left side view of the display device of fig. 1.

In one embodiment, the display device provided herein includes a display screen 100, a base bracket 200; the display screen 100 includes a screen body, a back plate 300 disposed at the rear of the screen body, and a rear case 400 installed with the back plate 300.

It should be noted that, in a display device such as a television, the portion above the base bracket 200 is the display screen 100; in the display screen 100, except the back plate 300, the rear case 400 and corresponding components, the remaining liquid crystal screen, the adaptive module and the like form a screen body.

In this embodiment, the display panel 100 further includes a main board, a power board, a speaker 500, and a connection bracket 600 for connecting the base bracket 200 and the display panel 100.

Further, referring to fig. 4 and 5, fig. 4 is a perspective view of the display device in fig. 2; fig. 5 is an exploded view of the display device of fig. 4.

On the basis of the above structure, as shown in fig. 4 and 5, the rear case 400 has a quadrangular shape, and the rear case 400 is installed in the middle area below the rear panel 300; the main board and the power board are arranged in a first cavity enclosed between the rear shell 400 and the back panel 300;

on both sides of the rear case 400, the rear plate 300 protrudes outward to form a second cavity, and the speaker 500 and the adapting bracket 600 are fixed in the second cavity.

In the above structure, since the rear case 400 has a quadrangular shape, the rear case 400 can be very conveniently installed at the middle region below the rear panel 300. In addition, the rear case 400 is changed from the original figure of several figures to a quadrangle, so that cavities, i.e., the second cavities above, can be formed at both sides of the rear case 400 by protruding from the rear of the rear plate 300 such that the corresponding speakers 500 and the adaptor bracket 600 are inserted into the cavities. Meanwhile, the power board and the main board extend into the cavity enclosed by the rear case 400 and the backplane 300, which is the first cavity in the foregoing.

In the above structure, since the rear case 400 is a quadrangle, for example, it may be a substantially rectangular or square shape, but it is not a strict rectangular or square shape since the corners are rounded. Because the rear shell 400 is quadrilateral and has small area, the four rear shells 400 can be ejected by one die during injection molding, namely, the four rear shells 400 can be ejected by one injection molding, so the injection molding efficiency is obviously improved, and the injection molding cost is obviously reduced.

In addition, the rear case 400 is quadrangular and is not irregular in a shape like a Chinese character 'ji', so that when the back plate 300 is installed, installation and fixation can be realized by adopting a clamping structure, and too many screws are not needed, so that the installation cost is also obviously reduced.

To sum up, the structural design of the display device provided by the application can enable the injection molding cost and the installation cost of the rear shell 400 to be remarkably reduced, so that the overall cost of the display device can be effectively reduced, and the market competitiveness is improved.

For example, an opening is formed at a corresponding position of the back plate 300 to form a downward insertion tongue 303; the upper part of the rear shell 400 is bent to form a U-shaped groove 401 with an upward opening, and the insertion tongue 303 is inserted into the U-shaped groove 401 to complete insertion.

In the above structure, as shown in fig. 7, since the opening is provided at the corresponding position of the back plate 300, the insertion tongue 303 facing downward is formed, and thus the rear case 400 has a possibility of insertion. On the basis, as shown in fig. 7, the upper portion of the rear shell 400 is bent to form a U-shaped groove 401 with an upward opening, and the insertion tongue 303 is inserted into the U-shaped groove 401 to complete insertion, so that insertion is finally achieved. The clamping structure dispenses with screw connection, so that the connection efficiency is very high and the connection cost is very low.

In any of the above embodiments, the clamping structure below the rear case 400 may be designed specifically. For example, referring to fig. 9, fig. 9 is a schematic view illustrating an installation structure of a lower portion of a rear case and a front case of the display device in fig. 4.
