[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of the utility model.

[0022] The LED display board disclosed in the utility model includes at least one display board body and at least one protective mask arranged on the front side of the display board body, the protective mask is formed with a plurality of evenly distributed accommodating through holes, and a plurality of LED lamp beads of the display board body are correspondingly placed in the plurality of accommodating through holes. In this way, by setting the protective mask, the LED lamp beads on the display board body can be effectively prevented from falling off due to collision with foreign objects, thereby playing a role in protecting the LED display board.

[0023] See also Figure 1 and Figure 2 In some embodiments, the LED display board includes at least one display board body 10 and at least one protective mask 20, wherein the display board body 10 includes an LED substrate 11, a conductive circuit (not shown in the figure) arranged on the LED substrate 11, and a plurality of LED lamp beads 12 arranged on the LED substrate 11 and electrically connected to the conductive circuit 11, and a plurality of accommodating through holes 200 are formed on the protective mask 20. The protective mask 20 is attached and fixed to the front side of the display board body 10, and the plurality of LED lamp beads 12 are correspondingly placed in the plurality of accommodating through holes 200. The setting of the protective mask 20 plays a role in protecting the LED lamp beads 12 from collision with foreign objects.

[0024] In the preferred embodiment shown in the accompanying drawings, the LED display board is a grid-type LED display board, the LED substrate 11 is evenly distributed with a plurality of first transparent holes 110, the conductive circuit and the LED lamp beads 12 are installed in the non-first transparent hole area of ​​the LED substrate 11, and the protective mask 20 is formed with a plurality of second transparent holes 201 corresponding to the plurality of first transparent holes 110, so that the protective mask 20 is prevented from covering the first transparent holes 110 of the LED substrate 11, thereby ensuring the transparency of the LED display board.

[0025] Preferably, the depth of the accommodating through hole 200 is substantially equal to the protruding height of the LED lamp bead 12, that is, the ratio of the depth of the accommodating through hole 200 to the protruding height of the LED lamp bead 12 is 1:0.9-1.1, thereby preventing the LED lamp bead 12 from excessively protruding from the protective mask 20 or excessively recessed into the protective mask 20, thereby protecting the LED lamp bead 12 from collision with foreign objects and preventing the protective mask 20 from blocking the light of the LED lamp bead 12.

[0026] Combination Figure 3 As shown, in this embodiment, the protective mask 20 is fixed to the front side of the LED substrate 11 by means of a snap-fitting manner, a plurality of snap-fitting components 202 are formed on the back side of the protective mask 20, and a plurality of card interfaces 111 corresponding to the snap-fitting components 202 are formed on the LED substrate 11. The plurality of snap-fitting components 202 are correspondingly snapped into the plurality of card interfaces 111, thereby realizing the connection between the protective mask 20 and the LED substrate 11.

[0027] In the preferred embodiment shown in the accompanying drawings, the clamping component 202 includes a cylindrical portion 2020 surrounding the second transparent hole 201 and two hook portions 2021 relatively formed on the outer side of the front end of the cylindrical portion 2020. The clamping interface 111 is the first transparent hole 110 of the LED substrate 11. The clamping component 202 is inserted into the card interface 111 and the hook portion 2021 is hooked on the back side of the LED substrate 11.

[0028] Preferably, the cylindrical portion 2020 is recessed backward from its front end and has a plurality of cutouts 2022 formed on its wall. With the provision of the cutouts 2022, when the card connector 202 is inserted into the card interface 111, its front end is squeezed by the card interface 111 and radially contracts, thereby facilitating the insertion of the card connector 202.

[0029] See also Figure 3 In the embodiment shown in the accompanying drawings, at least one protrusion 203 protruding inward from the side wall of the accommodating through hole 200 is formed in at least part of the accommodating through hole 200 of the protective mask 20, and the protrusion 203 is pressed against the LED lamp bead 12 to fix the protective mask 20 on the front side of the LED substrate 11.

[0030] In other embodiments, the protection mask 20 may also be fixed to the front surface of the LED substrate 11 by other suitable means such as gluing.

[0031] Referring to the drawings, the first through hole 110 is designed as a circular hole, and correspondingly, the second through hole 201 is also designed as a circular hole.

[0032] In some embodiments, a conductive or insulating plate material such as a glass fiber substrate, a metal substrate, a phenolic paper substrate, a composite substrate, etc. can be selected as the LED substrate 11, and the first through hole 110 is formed on the LED substrate 11 by a suitable processing method such as drilling, punching, or laser drilling. When a conductive substrate is used, it is necessary to ensure that the conductive circuit disposed thereon is insulated from the LED substrate 11.

[0033] The LED lamp bead 12 can be a SMD LED, and the LED lamp bead 12 can be welded to the conductive circuit by existing welding methods such as reflow soldering. In some embodiments, the LED driver chip can also be welded and fixed to the conductive circuit at the same time. The arrangement of the conductive circuit and its connection with the LED lamp bead 12 and the LED driver chip can be carried out by using existing technologies, which will not be described in detail here.

[0034] The protective mask 20 can be made of a material such as polycarbonate (PC) plastic and the like by integral molding.

[0035] In some embodiments, the LED display panel includes a plurality of display panel bodies 10, and the plurality of display panel bodies 10 are connected by at least one protective mask 20 to form an LED display panel. Figure 4 As shown, in this embodiment, a protective mask 20 can be used to splice multiple display panel bodies 10 into a whole. Figure 5 As shown, in this embodiment, two protective masks 20 can be used to splice three display panel bodies 10 into a whole. It can be understood that in other embodiments, other splicing methods can also be used. It can be seen that through the protective mask 20, multiple display panel bodies 10 can be spliced ​​together to form a larger LED display panel, without the need for additional components such as brackets, which helps to maintain the aesthetics of the LED display panel.
