DETAILED DESCRIPTION

[0055] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0056] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present utility model. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0057] In the related art, the door screen device usually includes a display device, a sound module, a power module, a mainboard, and a camera module for performing face recognition or shooting and recognizing a QR code. However, the existing door screen device often stacks all these structures together and then fixes them as a whole by wrapping the outer edges. Therefore, with the stacking of the display device, the camera module, the power module and other structures, the thickness of the door screen also increases, making it difficult to achieve lightness and thinness.

[0058] In addition, the display device and other structures themselves have frames and packaging structures around them. After the outer sides of these devices are edged, the frame of the door screen device will be further increased, making it difficult for existing door screen devices to achieve a narrow frame effect.

[0059] In order to solve the above technical problems, the utility model provides a display device, such as Figures 1 to 4 As shown, the display device includes a display screen 100, a middle frame 200, a rear cover plate 300 and a functional module 410. The display screen 100 and the rear cover plate 300 are both arranged in the middle frame 200. The middle frame 200 includes a front shell 210 and side strips 220 extending along the edge of the front shell 210 and connected end to end. The front shell 210 has a display opening 211 that passes through the front shell 210 along the thickness direction of the front shell 210. The front shell 210 also has a partition structure 212 on one side of the display opening 211. The display screen 100 corresponds to the display opening 211 and is located in a space defined by the partition structure 212 and multiple side strips 220. The functional module 410 and the display screen 100 are respectively located on both sides of the partition structure 212. The rear cover plate 300 is fixedly connected to the multiple side strips 220 to fix the display screen 100 between the front shell 210 and the rear cover plate 300. The functional module 410 includes at least one camera.

[0060] In the display device provided by the present invention, the partition structure 212 divides the internal space of the middle frame 200 into two parts. One side of the partition structure 212 and the side strips 220 around the display opening 211 surround to form a display screen setting area. The display screen 100 is fixed in the display screen 100 setting area by the rear cover plate 300, and the other side of the partition structure 212 and the remaining side strip structures surround to form an air avoidance area for accommodating the functional module 410. In addition to the functional module 410, modules such as a power supply can also be set in the air avoidance area, so that the display screen 100 and modules such as the functional module 410 are arranged on the same layer, thereby effectively reducing the stacking thickness of each module of the display device, which is conducive to realizing a thin and light display device product.

[0061] Furthermore, the display screen 100 is directly disposed in the display screen 100 setting area, and is directly connected to the middle frame 200 and the rear cover plate 300 as an integrated structure. The display screen 100 has no self-contained frame and packaging structure around it, and the display screen 100 is fixed by the structure on both sides and around it, without the need to set up an additional bracket structure for fastening connection, thereby effectively reducing the redundant structure around the display screen 100 and the outer surface of the display device, thereby reducing the frame width of the display device (that is, the distance between the edge of the display screen 100 and the side of the display device observed from the outside), thereby realizing a narrow frame of the display device.
