The direct-type display device of the embodiment of the invention, as shown in fig. 3, fig. 4 and fig. 5, includes a rear housing 1, a back plate 2, a middle frame 3, a diffusion plate 4 and a display panel 5, wherein a first end 31 of the middle frame 3 is close to the display panel 5 and fixed with a side of the display panel 5 and a side of the diffusion plate 4, a second end 32 of the middle frame 3 is close to the back plate and fixed with the back plate 2, since the first end 31 of the middle frame 3 and the second end 32 of the middle frame 3 are connected in an inclined manner in a direction toward the diffusion plate, the rear housing 1 is fixed on a side of the back plate 2 away from the display panel 5, and the second end 32 of the middle frame 3 is connected with a side of the. Therefore, the structure of the side of the display device is the middle frame 3, the side of the rear shell 1 only extends to the back panel 2 without extending to the display panel 5, and only one middle frame 3 inclined towards the direction of the diffusion plate is arranged in the distance from the middle frame 3 to the back panel 2, so that the side structure thickness of the display device can be reduced, the occupation ratio of the rear shell 1 is reduced, and the appearance effect is improved.
In order to fix the rear plate 2, the diffuser plate 4, and the display panel 5 well by the middle frame 3, as shown in fig. 4, 5, and 6, the middle frame 3 includes a first step surface 33, a second step surface 34, and a third step surface 35, the second step surface 34 is located between the first step surface 33 and the third step surface 35, the first step surface 33 is used to fix the display panel 5, the second step surface 34 is used to fix the diffuser plate 4, and the third step surface 35 is used to fix the rear plate 2. Further, by providing the first step surface 33, the second step surface 34, and the third step surface 35 on the bezel 3, the display panel 5, the diffuser plate 4, and the rear plate 2 can be fixed, respectively.

The fixing of the middle frame 3 and the back plate 2 can be realized in various ways, such as bonding, clamping, screw fixing, and the like. Wherein, the mode of joint is fixed firm inadequately, and the mode of screw fixation is installed and is dismantled very inconvenient relatively, and the screw easily makes whole display device's thickness increase, consequently, preferably adopts the mode of bonding. The bonding method needs to use glue, and preferably, as shown in fig. 7, the middle frame 3 and the back plate 2 are fixed by structural glue 7. The structural adhesive has high strength after being bonded, can bear larger load, is aging-resistant, fatigue-resistant and corrosion-resistant, has stable performance in the expected life, and is suitable for being used as an adhesive for bonding strong structural members.
Since the middle frame 3 is located outside the display device and is obliquely disposed, the middle frame 3 directly affects the appearance effect when viewed from the side of the display device.

It should be noted that, referring to fig. 1 and 2, the back plate 03 of the prior art is generally an iron plate, and is formed by a stamping process, and the edge of the back plate 03 is inclined to form a cavity for carrying the optical film. The shape of the punched back plate 03 is used for ensuring the light mixing distance of the direct type backlight module. However, since a certain spring back occurs after the stamping of the stamping part, the variation of the structural dimension is large, and thus the light mixing distance is not very stable. In the direct type display device according to the embodiment of the present invention, referring to fig. 4, 5 and 6, the middle frame 3 is disposed obliquely, the optical components (including the diffuser plate 4 and the display panel 5) are supported by the middle frame 3, and the middle frame 3 made of an aluminum alloy material has a stable structural dimension, so as to ensure an accurate and stable light mixing distance.
In order to further ensure the overall rigidity and strength of the back plate 2, it is preferable that the back plate 2 is made of a steel-plastic plate or an aluminum-plastic composite plate. When fixing lamp plate 6 on backplate 2 like this, better plane degree can be guaranteed to backplate 2.
The rear shell 1 and the back plate 2 can be fixed in a clamping manner and a fastening manner by using a fastening piece, and in order to ensure the fixing firmness, the rear shell 1 and the back plate 2 are fixedly connected by using the fastening piece. The fasteners may be screws or the like.
In order to further enhance the appearance, referring to fig. 8, the rear case 23 contacting the side of the end of the middle frame 22 near the rear side of the display device may be slightly inclined so as to contact the inclined middle frame 22, thereby further enhancing the side appearance. Referring to fig. 3, the display device generally further includes a front case 8 and a rubber frame 9 at the ground side.
It should be noted that, with the above arrangement, the direct-type display device according to the embodiment of the present invention can reduce the thickness of the side edge structure of the display device, reduce the ratio of the rear housing 1, and improve the appearance effect, and can be applied to various direct-type display devices, such as a television, a computer display, and the like, as required.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
