Referring to fig. 1a, a back plate of a conventional floating screen is formed by bending integrally, and includes a bottom wall 1, a first connecting wall 2 and a second connecting wall 3, which are connected in sequence, where the first connecting wall 2 and the bottom wall 1 are bent in an L shape, and the second connecting wall 3 and the bottom wall 1 are arranged in parallel. The cavity 4 for placing optical devices such as the optical diaphragm 5, the diffusion plate 6 and the reflector plate 7 is formed by enclosing the bottom wall 1 and the first connecting wall 2, and the second connecting wall 3 is used for shielding the optical devices to prevent the optical devices from falling. In the assembly process of the suspension screen, the back plate is fixed on the jig, and then optical devices such as the reflector plate 7, the diffusion plate 6 and the optical diaphragm 5 are sequentially placed in the cavity 4. Because the size that the second connects wall 3 to enclose the open-ended that closes the formation is less than the size of cavity 4, optical device must take place certain degree elastic deformation in the assembling process and just can get into in the cavity 4 by the opening, for avoiding optical device to pop out by the opening under the effect of elastic restoring force, the size A of second connection wall 3 has minimum reference value to ensure that second connection wall 3 forms the sheltering from to optical device. In addition, the process conditions for integrally molding the back plate may limit the size design of the second connecting wall 3. Due to the above factors, the dimension a of the second connecting wall 3 is large. After the back plate and the display screen are assembled into a whole, the part of the back plate exposed out of the display screen visually forms a frame structure surrounding the display screen, and the frame structure is large in size and does not accord with the development trend of narrow frames or even no frames. In addition, the process difficulty of integrally bending the back plate is high, the yield is low, the reject ratio is high, the manufacturing cost of integrally bending the back plate exceeds 15% of that of the conventional processing process, and the die cost exceeds 30% of that of the conventional die. In addition, please refer to fig. 1b, the back plate is used as the appearance member, and each bent corner has a larger rounded corner R, so that the design is visually weak and the ridge feeling is not sufficient.

Referring to fig. 2 and fig. 3, a display device 100 according to the present invention includes a back plate 10, a middle frame 20, and a display panel 30. The back plate 10 is formed with a cavity for accommodating other elements. The middle frame 20 is connected to the back plate 10, and the display panel 30 is disposed on a side of the middle frame 20 away from the back plate 10. The middle frame 20 serves as a mounting carrier for the display panel 30, and the arrangement of the middle frame 20 is beneficial to improving the overall strength of the back plate 10. In an embodiment, the display device 100 has an approximately rectangular parallelepiped appearance, the middle frame 20 includes four sub-frames connected in sequence, and in order to improve the strength of the middle frame 20 and enhance the aesthetic property of the middle frame 20, the four sub-frames of the middle frame 20 are designed as an integral structure.

The back plate 10 includes a main body portion 11 and a bending portion 12, which are disposed at an included angle, and the main body portion 11 and the bending portion 12 enclose to form an accommodating space so as to provide an installation space for other components. Specifically, the angle between the main body 11 and the bent portion 12 is 90 °. The angle between the main body portion 11 and the bend 12 ranges from 90 ° ± 2 ° in consideration of the machining accuracy. The material of backplate 10 is metals such as stainless steel, aluminum alloy or titanium alloy to guarantee the overall structure intensity of backplate 10, thereby form effective support to other subassemblies. In one embodiment, the back plate 10 may be formed by stamping.

The middle frame 20 is formed with a planar outer periphery 22 on a side facing the display panel 30, and the display panel 30 can be adhered to the planar outer periphery 22 of the middle frame 20 by using a double-sided tape or a foam tape, so as to achieve a floating structure design of the display panel 30, that is, the display panel 30 exhibits a visual effect of being suspended on the surface of the middle frame 20. By adopting the design of the suspension structure, the visible area 31(Active area, AA) of the display panel 30 can be effectively prevented from being blocked, and meanwhile, the size selection range of the display panel 30 is wider, and the compatibility between the back plate 10 and the middle frame 20 is stronger.

For the entire display device 100, the non-display area includes the non-visible area 32 of the display panel 30 and the portion 20a of the middle frame 20 exposed to the display panel 30, and the width C of the non-display area is approximately equal to the width a of the middle frame 20 in consideration of assembly error. The "bezel" means a distance from the visible region 31 of the display panel 30 to the edge of the display device 100, and when the user is positioned right in front of the display device 100, the width C of the non-display region is observed to be narrow, and the screen occupation ratio of the display device 100 is larger. The screen ratio refers to a ratio of an area of the visible region 31 to a total area of the display device 100. The smaller the width dimension a of the middle frame 20 toward the display panel 30 side, the larger the screen occupation ratio.

In addition, the bent portion 12 of the back plate 10 is connected to the middle frame 20, for example, the bent portion 12 is in interference fit with the fitting groove 21; or the bending part 12 and the middle frame 20 are bonded with each other by strong glue; alternatively, the bent portion 12 is engaged with a side wall of the fitting groove 21. The back plate 10 and the middle frame 20 can be connected in any one of the above connection manners, and a space for assembling with the back plate 10 is not required to be additionally arranged on the surface of the middle frame 20 facing the display panel 30, so that the width dimension a of the middle frame 20 is further reduced.

Meanwhile, the middle frame 20 is used as an appearance piece, the middle frame 20 is formed in an extrusion molding or injection molding mode, and the four top corners of the surface, facing the display panel 30, of the middle frame 20 can form 90-degree included angles, so that the ridge feeling of the periphery of the whole display device 100 can be improved, and the design feeling of a product is enhanced.
