The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

The display screen is used for displaying various information such as text, images and videos, as shown in fig. 1, fig. 1 is an exploded schematic view of a display screen in a thickness direction according to an embodiment of the present application, and the display screen includes a substrate 200, a light emitting module 300, a mask 400, a fastening assembly 500 and a bottom case 100. The cover 400 and the bottom chassis 100 enclose a space for accommodating the light emitting module 300 and the substrate 200. Specifically, the light emitting module 300 is disposed on the substrate 200, the substrate 200 is disposed on the bottom case 100, and the fastening assembly 500 is used for fixedly connecting the cover 400 with the bottom case 100. Further, the light emitting module 300 is located between the substrate 200 and the mask 400.

First, the substrate 200, the light emitting module 300, the cover 400, and the bottom chassis 100 will be described, respectively.

The substrate 200 may be a Printed Circuit Board (PCB), which is also called a PCB and used for carrying electronic components such as the light emitting module 300, and the light emitting module 300 is electrically connected to the substrate 200 to transmit electrical signals for the light emitting module 300 through the substrate 200. The substrate 200 includes a first surface 210 and a second surface 220, and further includes a side circumferential surface connecting the first surface 210 and the second surface 220, the first surface 210 of the substrate 200 is disposed toward the bottom case 100, and the light emitting module 300 is disposed on the second surface 220 of the substrate 200.

The light emitting module 300 may be an LED module, and LEDs are LEDs arranged together according to a certain rule and packaged together. The substrate 200 is provided with a printed circuit, the light emitting module 300 is electrically connected to the printed circuit on the substrate 200, and the printed circuit provides an electrical signal to the light emitting module 300, so that the light emitting module 300 can be turned on or off. As shown in fig. 3, fig. 3 is a perspective view of a partial structure of a display screen in an embodiment of the present application, in which a plurality of light emitting modules 300 are arranged on a substrate 200, and various information such as characters, images, and videos is displayed by turning on or off different light emitting modules 300.

The cover 400 generally serves as a protection function to protect the light emitting module 300 from dust and moisture. The mask 400 has a light-transmitting property, and in popular terms, a user can see the scenery on one side of the mask 400 through the mask 400 and then the scenery on the other side of the mask 400, so that the light emitted by the light-emitting module 300 can be transmitted through the mask 400.

That is, as shown in fig. 1, the bottom chassis 100 and the cover 400 enclose a space for accommodating the light emitting module 300 and the substrate 200, and the cover 400 is connected to the bottom chassis 100 by the fastening assembly 500. Fig. 2 is a schematic structural diagram of the bottom chassis 100 in an embodiment of the present application, the bottom chassis 100 includes a housing main body 110 and a mounting post 130 disposed on the housing main body 110, and with reference to fig. 1 and 2, a second mounting hole 230 is disposed on the substrate 200, a first mounting hole 430 is disposed on the cover 400, the mounting post 130 can be inserted into the second mounting hole 230, and the fastening assembly 500 can be inserted into the first mounting hole 430 and then locked with the mounting post 130, so as to achieve a fixed connection between the cover 400 and the bottom chassis 100. For example, as shown in fig. 2, the mounting post 130 may be provided with a threaded connection hole 133, the fastening assembly 500 may be a bolt or a screw having a threaded section, and the threaded section of the fastening assembly 500 is threaded into the threaded connection hole 133 of the mounting post 130 after passing through the first mounting hole 430. For another example, the mounting post 130 may be provided with a first snap structure, the fastener may be provided with a second snap structure, and after the fastening assembly 500 passes through the first mounting hole 430, the first snap structure is locked to the second snap structure on the mounting post 130.

It should be understood that, since the mounting posts 130 are used for locking with the fastening assemblies 500, so as to fixedly connect the cover 400 and the bottom case 100, the mounting posts 130 are required to bear a large locking force, the bottom case 100 is usually made of plastic materials, the bottom case 100 has a certain bending resistance, but when the locking force between the fastening assemblies 500 and the mounting posts 130 is large, the mounting posts 130 are still easy to break. In order to prevent the mounting post 130 from being broken, i.e., to increase the structural strength of the mounting post 130, the mounting post 130 may include a main cylinder 131 and a rib 132 connected to the main cylinder 131, the main cylinder 131 and the rib 132 are both connected to the case main body 110, and the rib 132 is disposed on the outer circumferential surface of the main cylinder 131 along the extending direction of the main cylinder 131. Here, the extending direction may be understood as an extending direction of the main column 131 being an axial direction thereof when the main column 131 is a cylinder, or may be understood as a height direction of the mounting column 130. The convex ribs 132 are arranged on the main column 131, so that the structural strength of the main column 131 is increased, and compared with the single thin main column 131, the mounting column 130 has stronger tensile and bending resistance, can bear larger locking force, and is not easy to break.

In one embodiment, as shown in fig. 2, the mounting post 130 includes a main column 131 and at least two ribs 132, the two ribs 132 and the main column 131 are both connected to the housing main body 110, the two ribs 132 are disposed on the outer circumferential surface of the main column 131 along the extending direction of the main column 131, and the two ribs 132 are disposed opposite to each other in the circumferential direction of the main column 131, for example, the two ribs 132 are disposed on both sides of the main column 131 along the radial direction of the main column 131, that is, the two ribs 132 are disposed at an interval of 180 degrees in the circumferential direction of the main column 131. When the mounting post 130 is bent, one of the ribs 132 is under tensile stress, the other rib 132 is under compressive stress, and the two ribs 132 cooperate to reinforce the structural strength of the main column 131.

For another example, as shown in fig. 2, the mounting post 130 includes a main column 131 and at least two ribs 132, the two ribs 132 and the main column 131 are both connected to the casing main body 110, the two ribs 132 are disposed on the outer circumferential surface of the main column 131 along the extending direction of the main column 131, and the two ribs 132 are disposed at intervals of 90 degrees in the circumferential direction of the main column 131. When the mounting post 130 is bent, the two ribs 132 may both receive tensile stress, or the two ribs 132 may both receive compressive stress, and the two ribs 132 act together to reinforce the structural strength of the main column 131.

Of course, the relative position of the ribs 132 and the main column 131 is not limited to the structure in the above embodiment, for example, four ribs 132 may be provided, and the four ribs 132 are arranged at equal intervals along the circumferential direction of the main column 131. In the present application, the strength of the mounting post 130 is increased by disposing the ribs 132 at intervals around the outer circumference of the main column 131, rather than increasing the cross section of the main column 131 as a whole to increase the strength of the main column 131. As shown in fig. 1, the base plate 200 is provided with a second mounting hole 230, and the mounting post 130 needs to be inserted into the second mounting hole 230 to lock with the fastening assembly 500, which will increase the diameter of the second mounting hole 230 if the cross section of the main column 131 is increased to increase the strength of the main column 131. Since the substrate 200 may be a PCB on which the light emitting modules 300 and the printed circuits are disposed, when the light emitting modules 300 or the printed circuits are distributed densely, the second mounting holes 230 with a larger aperture interfere with the light emitting modules 300 and the printed circuits.

As shown in fig. 4, fig. 4 is a top view of a partial structure of a display screen in an embodiment of the present application, a bottom chassis 100 of the display screen includes a housing main body 110 and a frame 120, and the frame 120 is disposed on the housing main body 110. The bottom case 100 is generally manufactured by an injection molding process, for example, a molten plastic liquid is injected into a cavity of a molding die, and when the outer frame 120 has a thin-wall structure, the cavity of the molding die is also narrow, so that the molten plastic liquid may not sufficiently fill the whole cavity, and the outer frame 120 may have an uneven thickness or even be broken. Therefore, the plurality of protruding strips 121 are arranged on the outer frame 120, and the protruding strips 121 form a large space corresponding to the cavity of the molding die, so that the molten plastic liquid can be easily and sufficiently buffered, and the outer frame 120 formed by injection molding can not be broken. And the structural strength of the outer frame 120 of a thin-wall structure is also increased by providing the convex strips 121 on the housing.

The bottom case 100 has an inner cavity, and the protruding strips 121 on the outer frame 120 can be disposed on the surface of the outer frame 120 located in the inner cavity; the convex strips 121 on the outer frame 120 can also be arranged on the outer surface 410 of the outer frame 120; the ribs 121 on the frame 120 can also be disposed on both the inner cavity surface and the outer surface 410 of the frame 120. Of course, the ribs 121 may be hidden in the inner cavity of the bottom case 100 for aesthetic reasons.

As shown in fig. 4, the cross-sectional shape of the ridge 121 may be semicircular, triangular, rectangular, or the like.

In order to ensure that the mask 400 has good light transmittance, the mask 400 may be made of transparent materials such as polycarbonate material, transparent acrylic material, transparent glass, etc., so that the light transmittance of the mask 400 may reach 90% to 91%.

The mask 400 may be spaced apart from the substrate 200 such that a spacing gap is formed between the mask 400 and the substrate 200. The mask 400 is provided with a first mounting hole 430, the first mounting hole 430 is a through hole and extends along the thickness direction of the mask 400, that is, the first mounting hole 430 penetrates through two oppositely arranged surfaces of the mask 400, so that the first mounting hole 430 is communicated with the space and the outside. The fastening member 500 may be inserted into the first mounting hole 430.

Specifically, the two oppositely disposed surfaces of the face mask 400 are an inner surface 420 and an outer surface 410 of the face mask 400, the inner surface 420 of the face mask 400 defining part of the boundary of the spacing gap, and the outer surface 410 of the face mask 400 being in direct contact with the outside world. The inner surface 420 and the outer surface 410 are oriented in opposite directions, and the first mounting hole 430 can extend through the inner surface 420 and the outer surface 410 of the mask 400. The shape of the mask 400 may be a rectangular flat plate, the shape of the mask 400 may be a circular, oval, or flat surface that is distorted more or less, or the shape of the mask 400 may be a curved surface, for example, a curved surface in the shape of an arc or a curved surface in the shape of a wave.
