As shown in FIG. 1, generally the display device comprises a backplane 01, a front frame 02, a side frame 03, a backlight module and a display panel 06. For convenience of description, it is supposed that along a direction parallel to a light emergent surface of the display panel 06, the side facing an interior side of the display device is referred to as “inner”, while the side facing an external side of the display device is referred to as “outer”. The backplane 01 includes a base plate 012 and a plurality of side plates 011 to form a mounting tank for the backlight module. The backlight module includes a reflective sheet 05, a light source 041, a light guide plate 042 and an optical membrane 043, which are mounted in the mounting tank. The side frame 03 and the backplane 01 are fixedly connected as a support structure for supporting the display panel 06. A fixing plate 023 of the front frame 02 is engaged with the backplane 01 through an engagement structure 021, and a pressing plate 024 on the front frame 02 is affixed with a pad 022, to form a structure pressing the display panel 06 on both upper and lower sides; there is provided with a pad 031 between the side frame 03 and the display panel 06. The frame assembly of the display device includes the backplane 01, the front frame 02 and the side frame 03.

For at least one group of a side plate 11, a pressing plate 22 and a fixing plate 21 that corresponding to each other, a structure as follows is comprised: the fixing plate 21 is fixed on the side frame 4, and an outer surface of the fixing plate is not higher than an outer surface of the side plate 11; the side frame 4 is provided with an elastic pad 3 located on an inner side of the fixing plate 21, an inner surface of the elastic pad 3 forms a step surface 33 for supporting and limiting the display panel 6, and the elastic pad 3 abuts against the pressing plate 22 and the fixing plate 21, and a projection of the side frame 4 and a projection the elastic pad 3 in a plane of a side surface, facing the pressing plate 22, of the side plate 11 of the backplane 1 are located within the side surface, facing the pressing plate 22, of the side plate 11.

In the frame assembly A, the side frame 4 and the side plate 11 of the backplane 1 are fixedly connected, and the fixing plate 21 of the front frame 2 is fixed on the side frame 4, to ensure stability of the connection among the front frame 2, the side frame 4, and the backplane 1. In the meantime, the side frame 4 and the side plate 11 of the backplane 1 coordinate to form a step surface 114 for supporting the fixing plate 21, and one side, facing the base plate 12 of the backplane 1, of the fixing plate 21 is supported on the step surface 114, to make sure that the fixing plate 21 is accommodated in the step surface 114 in a direction parallel to a light emergent surface of the display panel 6. A support limitation structure for the display panel 6 can be formed between the pressing plate 22 of the front frame 2 and the step surface 33 of the elastic pad 3 to ensure stability of the display panel 6 after installation. After the front frame 2, the side frame 4, the backplane 1, and the elastic pad 3 are installed, an outer surface of the fixing plate 21 of the front frame 2 is not higher than an outer surface of the side plate 11 of the backplane 1, and a projection of the side frame 4 and a projection of the elastic pad 3 in a plane of a side surface, facing the pressing plate 22, of the side plate 11 of the backplane 1 is located within the side surface, facing the pressing plate 22, of the side plate 11. Therefore, a width of the frame assembly A is a thickness of the side plate 11 of the backplane 1, as indicated by D2 in FIG. 2.

Thus, the frame assembly A facilitates achieving a narrow frame design of a display device.

For example, as shown in FIG. 2, in the frame assembly A, the side frame 4 and the side plate 11 coordinate to form the step face 114 located on an outer side of the side frame 4 to support the fixing plate 21.

For example, in an embodiment, as shown in FIG. 2, the side frame 4 is provided with a slot 43 having an opening facing the pressing plate 22. As shown in FIG. 2, a side surface, facing away from the pressing plate 22, of the elastic pad 3 contains a protrusion 31 to be plugged into the slot 43, and the elastic pad 3 is mounted on the side frame through the slot 43 and the protrusion 31.

For example, as shown in FIG. 2, the side frame 4 may include a first frame assembly 41 and a second frame assembly 42, the first frame assembly 41 is located on an outer side of the second frame assembly 42, and the slot 43 is formed between the first frame assembly 41 and the second frame assembly 42.

There are a variety of ways for setting the elastic pad 3.

For example, as shown in FIG. 6, in the case where the elastic pad 3 includes a plurality of sub-elastic pads, and the plurality of sub-elastic pads are evenly distributed on the side frame 4, the slots 43 provided on the side frame 4 corresponds to the sub-elastic pads one by one. That is, the slots 43 provided on the side frame 4 are of a segmented type, and a portion 44 of the side frame 4 located between any two adjacent segments of the slots 43 is of a solid structure, and thus can enhance a mechanical strength of the side frame 4, and improve stability of the front frame 2 and the side frame 4 after assembly.

In another embodiment, as shown in FIG. 7, a side surface, facing away from the pressing plate 22, of the elastic pad 3 contains a slot 34, a side surface, facing the pressing plate 22, of the side frame 4 has a protrusion 44 plugged into the slot 34, and the elastic pad 3 is mounted on the side frame 4 through the slot 34 and the protrusion 44. FIG. 8 is a schematic diagram of the display device comprising the frame assembly. FIG. 9 is a dismantlement schematic diagram of the display device.
