[0015] In some embodiments, in the first direction, the length of the fourth light-blocking plate is the same as the length of the second panel portion.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] LED displays are commonly found on the exterior walls or glass curtain walls of buildings, landmark structures, and large advertising screens. An LED display typically consists of LED modules and a cabinet. The LED modules are assembled onto the cabinet to form the LED display for easy combination and use. However, during use, the residual light emitted by the LED beads on the LED module's light board can cause interference, leading to problems such as white bars and screen distortion on the LED display.

[0037] Based on the above considerations, in order to solve the problem of mutual interference between the residual light emitted by the LED beads on the lamp board of the LED module in related technologies, which affects the display effect, a mask is designed. This mask has light holes in its main body for the LED beads on the lamp board to pass through. Simultaneously, multiple sets of first light-blocking components are used to correspondingly block multiple sets of socket groups. Two first light-blocking plates spaced apart along a second direction block the LED beads passing through the socket groups in the second direction, thereby reducing the residual light interference between the spaced-apart LED beads in the second direction. Furthermore, second light-blocking plates of the second light-blocking components are spaced apart along a first direction between the two first light-blocking plates of each set of first light-blocking components, thus enabling the second light-blocking plates to block the LED beads spaced apart along the first direction, further reducing the residual light interference between the spaced-apart LED beads in the first direction. Therefore, when the mask provided in this embodiment is applied to the lamp board of the LED module, the display effect of the LED module is superior.

[0038] The face mask provided in this application will now be described in detail according to specific embodiments.

[0039] Please refer to Figures 1 to 3 In a first aspect, embodiments of this application provide a face mask 1000, which is used to cover the light-emitting surface of a lamp panel. The face mask 1000 includes a face mask body 300, multiple sets of first light-blocking components 100, and multiple sets of second light-blocking components 200. The face mask body 300 has multiple lamp holes 301 for the lamp beads of the lamp panel to pass through. The multiple lamp holes 301 are arranged sequentially along a first direction X to form multiple sets of insertion hole groups 302, and the multiple sets of insertion hole groups 302 are arranged sequentially at intervals along a second direction Y. The first direction X is perpendicular to the second direction Y. The light-blocking component 100 is used to correspond to multiple sets of socket groups 302 of the enclosure. The first light-blocking component 100 includes two first light-blocking plates 110 arranged at intervals along the second direction Y. The socket group 302 is located between the two first light-blocking plates 110. A second light-blocking component 200 is arranged between the two first light-blocking plates 110 of each first light-blocking component 100. The second light-blocking component 200 includes multiple second light-blocking plates 210, which are arranged at intervals along the first direction X. At least one lamp hole 301 is arranged between two adjacent second light-blocking plates 210.

[0040] The mask 1000 refers to the cover structure used to cover the light-emitting surface of the lamp panel.

[0041] The mask 1000 includes a mask body 300, which refers to the main part of the mask 1000. For example, the mask body 300 can be used to connect with a lamp panel. The mask body 300 has a plurality of lamp holes 301, so that when the mask 1000 is placed on the lamp panel, the lamps on the lamp panel can be correspondingly inserted through the lamp holes 301 and exposed on the mask body 300 to achieve the effect of light emission display.

[0042] The lamp hole 301 can be a separate, independent through hole; or, the lamp hole 301 can be a row of holes, that is, two or more through holes connected to form a row of holes. For example, in some embodiments, the lamp hole 301 can be a group of three through holes connected to form a group of holes, so that every three lamp beads on the lamp board can be a group and simultaneously exposed from the above-mentioned group of holes to form a pixel.

[0043] Multiple lamp holes 301 are arranged sequentially along the first direction X to form multiple sets of socket groups 302; optionally, the number of socket groups 302 can be any number of two, three, or more. The multiple sets of socket groups 302 are arranged sequentially at intervals along the second direction Y; multiple sets of socket groups 302 are used to simultaneously insert multiple rows of lamp beads from the lamp board, so that the lamp beads can be exposed on the mask body 300 and emit light for display.

[0044] Wherein, the first direction X can be any direction parallel to the surface of the mask body 300, and the second direction Y is a direction perpendicular to the first direction X. For example, in some embodiments, the first direction X can be the length direction of the mask body 300, and the second direction Y can be the width direction of the mask body 300.

[0045] The first light-blocking component 100 is used to correspond to the enclosure socket group 302; it should be understood that the number of the first light-blocking components 100 is the same as the number of socket groups 302, and each group of first light-blocking components 100 corresponds to a row of socket groups 302 on the enclosure.

[0046] The first light-blocking assembly 100 includes two first light-blocking plates 110 spaced apart along the second direction Y. Thus, the two first light-blocking plates 110 can be respectively disposed on opposite sides of the socket assembly 302 along the second direction Y, i.e., the socket assembly 302 is located between the two first light-blocking plates 110. It should be understood that when the mask 1000 covers the light-emitting surface of the lamp panel, the height of the lamp beads passing through the lamp holes 301 and extending out of the mask body 300 should not be higher than the height of the first light-blocking plates 110. In this way, the first light-blocking plates 110 can sufficiently block the residual light emitted by the lamp beads along the second direction Y.

[0047] The second light-blocking assembly 200 includes a plurality of second light-blocking plates 210, which are spaced apart along the first direction X. The second light-blocking plates 210 can separate one or more lamp holes 301 along the first direction X, so that the second light-blocking plates 210 can fully block the residual light emitted by the lamp beads passing through the lamp holes 301 along the first direction X.

[0048] The face mask 1000 provided in this application embodiment provides a light hole 301 on the face mask body 300 for the light hole 301 to pass through on the light plate. Simultaneously, multiple sets of first light-blocking components 100 are used to correspondingly surround multiple sets of socket groups 302. Two first light-blocking plates 110 spaced apart along the second direction Y are used to surround the lamp beads passing through the socket groups 302 in the second direction Y, thereby reducing the residual light influence between the spaced-apart lamp beads in the second direction Y. At the same time, the second light-blocking plates 210 of the second light-blocking components 200 are spaced apart along the first direction X to block the light from each set of first light-blocking components 100. Between the two first light-blocking plates 110, the second light-blocking plate 210 can be used to surround the LED beads spaced apart along the first direction X, thereby reducing the residual light influence between the LED beads spaced apart along the first direction X. Thus, when the mask 1000 provided in this embodiment is placed on the light-emitting surface of the lamp panel, the first light-blocking component 100 and the second light-blocking component 200 can block the LED beads passing through the lamp hole 301 in the first direction X and the second direction Y. The residual light influence between the LED beads of the lamp panel is lower, the probability of white bars, screen distortion, etc. appearing when the lamp panel is displayed is lower, and the display effect of the lamp panel is better.

[0049] Please refer to Figures 1 to 3 In some embodiments, a plurality of first gaps 111 are provided on the first light-blocking plate 110, and the plurality of first gaps 111 are distributed sequentially on the first light-blocking plate 110 along the first direction X; in the second direction Y, the projection of the first gaps 111 is staggered with the lamp beads.

[0050] Understandably, the first gap 111 refers to the notch structure on the first light-blocking plate 110, through which the first light-blocking plate 110 can connect the left and right sides in the second direction Y.

[0051] It should be understood that when the first light-blocking plate 110 blocks the opposite sides of the lamp bead in the second direction Y, the residual light of the lamp bead will form diffuse reflection between the mask body 300 and the two spaced first light-blocking plates 110.

[0052] In order to reduce the impact of diffuse reflection on the display caused by light between the two first light-blocking plates 110 of the first light-blocking assembly 100 and the mask body 300, a first gap 111 can be opened on the first light-blocking plate 110, so that when light is diffusely reflected, it can be reflected outward from the first gap 111, thereby reducing the impact of diffuse reflection on the display.

[0053] Meanwhile, in the second direction Y, the projection of the first gap 111 is staggered with the lamp bead, so as to prevent the light emitted by the lamp bead from being directly projected outward through the first gap 111; thus, the first gap 111 can reduce the influence of diffuse reflection and have a low impact on the light blocking effect of the first light blocking plate 110.

[0054] Optionally, the number of first gaps 111 opened on the first light-blocking plate 110 can be any number.

[0055] Please refer to Figures 1 to 3 In some embodiments, the first light-blocking component 100 further includes two third light-blocking plates 120 spaced apart along the second direction Y, the two third light-blocking plates 120 being located on opposite sides of the two first light-blocking plates 110; a plurality of third gaps 121 are formed on the third light-blocking plates 120, the plurality of third gaps 121 being sequentially distributed on the third light-blocking plates 120 along the first direction X; in the second direction Y, the projections of the first gaps 111 and the projections of the third gaps 121 are separated.

[0056] The first light-blocking assembly 100 further includes a third light-blocking plate 120, which is disposed on the mask body 300 and located on the side opposite to the two first light-blocking plates 110. Thus, the third light-blocking plate 120 can enhance the light-blocking effect outside the first light-blocking plates 110, and can also block the light-blocking gap of the first light-blocking plates 110, thereby further reducing the impact caused by the light from the LEDs being projected outward through the first gap 111.

[0057] Meanwhile, a third gap 121 is provided on the third light-blocking plate 120. The third gap 121 refers to the notch structure on the third light-blocking plate 120, through which the third light-blocking plate 120 connects the left and right sides in the second direction Y. Thus, when light passes through the first gap 111 and is projected between the first light-blocking plate 110 and the third light-blocking plate 120, the light will undergo diffuse reflection between the first light-blocking plate 110 and the third light-blocking plate 120; the third gap 121 can refract the light to the outside, thereby reducing the impact of diffuse reflection between the first light-blocking plate 110 and the third light-blocking plate 120.

[0058] Furthermore, in the second direction Y, the projections of the first gap 111 and the third gap 121 are separated; that is, in the second direction Y, the first gap 111 and the third gap 121 cannot be set to face each other; this can effectively reduce the influence of residual light between adjacent lamp beads caused by light directly passing through the first gap 111 and the third gap 121 in sequence and projecting outward.

[0059] Please refer to Figures 1 to 3In some embodiments, the mask body 300 includes a plurality of first panel portions 310 and a plurality of second panel portions 320; the plurality of first panel portions 310 are distributed sequentially at intervals along a second direction Y, and the length direction of the first panel portions 310 faces the first direction X; the plurality of second panel portions 320 are distributed sequentially at intervals along the second direction Y; at least one first panel portion 310 has a second panel portion 320 disposed on opposite sides in the first direction X, and the second panel portion 320 connects two adjacent first panel portions 310; wherein, each first panel portion 310 is provided with a row of socket groups 302 along the first direction X, and each first panel portion 310 is respectively provided with a set of first light-blocking components 100 and a set of second light-blocking components 200.

[0060] The first panel portion 310 refers to a part that makes up the mask body 300. In some embodiments, the first panel portion 310 may be elongated, and the length direction of the first panel portion 310 is oriented toward the first direction X; thus, a plurality of lamp holes 301 may be formed on each first panel portion 310 along the first direction X, so that a row of socket groups 302 are formed on each first panel.

[0061] Meanwhile, each of the first panels is provided with a set of first light-blocking components 100 and a set of second light-blocking components 200, such that the two first light-blocking plates 110 of the first light-blocking component 100 are distributed at opposite ends of the first surface along the second direction Y and surround the socket group 302 between them, and the multiple second light-blocking plates 210 of the second light-blocking component 200 are sequentially and spaced apart between the two first light-blocking plates 110 along the first direction X, so that the first light-blocking plates 110 and the second light-blocking plates 210 separate the multiple lamp holes 301 in the socket group 302.

[0062] The second panel portion 320 refers to another part constituting the face mask 1000. A plurality of second panel portions 320 are sequentially spaced along a first direction X, and at least one first panel portion 310 has second panel portions 320 disposed on opposite sides in the second direction Y; exemplaryly, in some embodiments, each first panel portion 310 has a second panel portion 320 disposed on opposite sides, and the second panel portions 320 are respectively distributed along the first direction X at opposite ends and the middle of the first panel portion 310, such as... Figure 1 As shown, the first panel portion 310 and the second panel portion 320 can be combined to form a frame-type mask body 300.

[0063] Please refer to Figures 1 to 3In some embodiments, the mask 1000 further includes multiple sets of third light-blocking components 400, which are respectively disposed on corresponding second panel portions 320; the third light-blocking component 400 includes a fourth light-blocking plate 410, which is disposed along the first direction X in its length direction, and is connected to the second panel portion 320 and used to separate the third light-blocking plates 120 on adjacent first panel portions 310; multiple fourth gaps 411 are provided on the fourth light-blocking plate 410, and the multiple fourth gaps 411 are sequentially distributed on the fourth light-blocking plate 410 along the first direction X; in the second direction Y, the projection of the third gap 121 is separated from the projection of the fourth gap 411.

[0064] The mask 1000 also includes multiple sets of third light-blocking components 400; the third light-blocking components 400 are disposed on each of the second panel portions 320 and are used to separate the jack groups 302 at opposite ends of the second panel portions 320 along the second direction Y.

[0065] The third light-blocking component 400 includes a plurality of fourth light-blocking plates 410 spaced apart along the second direction Y; optionally, the number of fourth light-blocking plates 410 can be any number of one, two, three or more; multiple fourth light-blocking plates 410 are used to form multiple shielding protection between two adjacent groups of first light-blocking components 100.

[0066] Meanwhile, a fourth gap 411 is provided on the fourth light-blocking plate 410, and the projections of the fourth gaps 411 on two adjacent fourth light-blocking plates 410 in the second direction Y are separated; that is, the fourth gaps 411 on two adjacent fourth light-blocking plates 410 cannot be arranged opposite each other in the second direction Y. It should be understood that when the light projected by the lamp bead is refracted through the first gap 111 and the third gap 121 in sequence, the light will be diffusely reflected on the fourth light-blocking plate 410 and the second panel portion 320, thereby affecting the overall display effect of the lamp panel. By providing a fourth gap 411 on each fourth light-blocking plate 410, and the fourth gaps 411 of adjacent fourth light-blocking plates 410 are not directly opposite each other, the light will pass through the fourth gaps 411 of each fourth light-blocking plate 410 respectively during the refraction process, so that the light is refracted and weakened between the multiple layers of fourth light-blocking plates 410, thus effectively reducing the impact of diffuse reflection formed on the second panel portion 320 on the display effect of the lamp panel.

[0067] Please refer to Figures 1 to 3 In some embodiments, in the first direction X, the length of the fourth light-blocking plate 410 is the same as the length of the second panel portion 320.

[0068] In this embodiment, the length of the fourth light-blocking plate 410 is set to be the same as the length of the second panel portion 320, that is, the fourth light-blocking plate 410 can completely separate the second panel portion 320 on the second panel portion 320, so as to further improve the separation and weakening effect of the fourth light-blocking plate 410 on the light projected in the first gap 111 and the third gap 121, thereby further reducing the probability of diffuse reflection on the second panel portion 320 affecting the display effect.

[0069] Please refer to Figures 1 to 3 In some embodiments, when the lamp bead is inserted through the lamp hole 301 and located between the two first light-blocking plates 110, the height of the lamp hole 301 does not exceed the height of the first light-blocking plate 110; the height of the second light-blocking plate 210 is greater than the height of the first light-blocking plate 110.

[0070] In this embodiment, the exposed height of the lamp bead through the lamp hole 301 is set to not exceed the height of the first light-blocking plate 110, so that the first light-blocking plate 110 can completely enclose and cover the lamp bead in the second direction Y.

[0071] Meanwhile, the height of the second light-blocking plate 210 is set to be greater than the height of the first light-blocking plate 110. In this way, the second light-blocking plate 210 can be used to form a contact support, thereby reducing the probability of the lamp bead colliding with the external structure.

[0072] Please refer to Figures 1 to 3 Secondly, this application embodiment also provides an LED module, including a lamp board, a support member, and a mask 1000 as described above. The lamp board is connected to the support member, and the mask 1000 covers the lamp board so that the lamp beads of the lamp board pass through the lamp holes 301 of the mask body 300.

[0073] The LED module provided in this application embodiment includes the aforementioned mask 1000, thereby improving the display effect of the LED module.

[0074] Please refer to Figures 1 to 3 Thirdly, embodiments of this application also provide an LED display screen, including a housing and an LED module as described above, wherein the LED module is connected to the housing.

[0075] The LED display screen provided in this application embodiment includes the above-mentioned LED module, thereby improving the display effect of the LED display screen.

[0076] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
