In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1 to 3, the LED mask of the present embodiment includes a first panel layer 10, a second panel layer 20, and a metal elastic sheet layer 30, wherein the metal elastic sheet layer 30 is embedded between the first panel layer 10 and the second panel layer 20, the first panel layer 10 and the second panel layer 20 are both provided with a bending groove 101, and the bending groove 101 of the first panel layer 10 is aligned with the bending groove 101 of the second panel layer 20.

Use this technical scheme's LED face guard, through covering first panel layer 10 and second panel layer 20 to metal bullet piece layer 30 and press from both sides tight assembly, and through set up corresponding groove 101 of buckling on first panel layer 10 and second panel layer 20, make the LED face guard buckle along bending groove 101 when buckling, at this moment, because metal bullet piece layer 30 self good elasticity and tensile strength, the LED face guard can freely be crooked along bending groove 101, and can reply the flat state under the effect of the elastic restoring force of metal bullet piece layer 30. When LED that will this LED face guard was used buckles in the screen product, the LED buckles the distance range of the interval of buckling between the LED module in the screen can guarantee within 5% of standard interval distance, ensures the good display effect of LED screen of buckling.

In the LED mask of this embodiment, the metal elastic sheet layer 30 is provided with light passing holes 31 for passing light, and each light passing hole 31 corresponds to each LED light emitting patch light source on the LED module one to one, so that the light emitted by the LED patch light source can be emitted through the light passing hole 31 for displaying.

In the process of stacking and assembling the first panel layer 10, the second panel layer 20 and the metal elastic sheet layer 30, the first panel layer 10 and the second panel layer 20 need to be stably connected, and the delamination of the first panel layer 10 and the second panel layer 20 is avoided in the process of bending along the bending groove 101, so that the metal elastic sheet layer 30 is provided with a connecting hole 32 for connecting the first panel layer 10 and the second panel layer 20. In the production process, in the pre-designed mold, the first panel layer 10 is firstly laid flat, then the metal elastic sheet layer 30 is placed on the first panel layer 10, and then the second panel layer 20 is covered on the metal elastic sheet layer 30, so that the molten materials of the first panel layer 10 and the second panel layer 20 flow through the connecting holes 32 to form effective connection. Moreover, the connection holes 32 are distributed in a rectangular array, so that the first panel layer 10 and the second panel layer 20 are stably connected through the connection points formed by the connection holes 32 distributed in the rectangular array, and thus, within the normal bending range of the bending groove 101, delamination between the first panel layer 10 and the second panel layer 20 does not occur, which affects the normal use of the LED mask.

In order to simplify the difficulty of the production process of the first panel layer 10 and the second panel layer 20 and improve the production efficiency, the bisector of the plane of the first panel layer 10 coincides with the central axis of the bending groove 101 thereon, and the bisector of the plane of the second panel layer 20 coincides with the central axis of the bending groove 101 thereon. Therefore, the design difficulty of the design die can be greatly reduced, the production cost of the die is reduced, and the forming efficiency of the bending groove 101 is facilitated.

The LED bent screen comprises a plurality of face masks 210 and a plurality of LED modules 220, wherein the face masks 210 are the LED face masks, the face masks 210 are formed by splicing and arranging in a straight shape, the LED modules 220 are installed on the face masks 210, the spacing gaps between every two adjacent LED modules 220 and the bent grooves 101 in the face masks 210 are arranged in a one-to-one correspondence mode, and the splicing positions 230 between every two adjacent face masks 210 are spanned by the LED modules 220. Thus, in the process of bending the LED bending screen, the LED mask can be bent along the designed bending groove 101, and a larger LED mask formed by splicing a plurality of LED masks cannot break at the splice 230, but the splice 230 is spanned by the LED module 220 to provide traction strength, so as to ensure the integrity of the LED mask.

Preferably, the area of each LED module 220 in the LED bending screen of the present embodiment is the same as the area of each mask 210, and since the bisector of the plane of the first panel layer 10 coincides with the central axis of the bending groove 101 thereon and the bisector of the plane of the second panel layer 20 coincides with the central axis of the bending groove 101 thereon, the alignment and assembly of the LED modules 220 and the LED masks is simplified, and the purpose of quick connection and assembly is achieved by quick alignment. Alternatively, in another possible embodiment, the length of each LED module 220 is equal to the length of each face mask 210, and the width of each LED module 220 is an integer multiple of the width of each face mask 210, such as 2 times, 3 times, 4 times, 5 times, and so on. In this way, the LED cover is joined in the width direction to form a large cover that can cover the entire LED module 220.

When utilizing LED to buckle the screen and show the figure content, through designing the LED light emitting component one-to-one setting on logical unthreaded hole 31 on the LED face guard and the LED module 220 to can all shine away and form the picture that shows the image simultaneously with the light that every LED paster light source of LED module 220 sent, make the demonstration of LED buckling the screen complete, the display effect is clear.

As shown in fig. 7, the LED bent panel with the display surface being a wave-shaped curved surface is obtained by bending the LED bent panel in a flat state along each of the bent grooves 101 in a wave-shaped curve. As shown in fig. 8, the LED bent panel having the display surface with the convex curved surface is obtained by bending the LED bent panel in the flat state toward one side of the LED module 220 along each of the bending grooves 101. In addition, the display surface of the LED bending screen in a flat state can be bent to form an inner circular shape, an outer circular shape and the like.

In this technical scheme, first panel layer 10, second panel layer 20 all adopts transparent plastic material to make, make the insulating properties of LED face guard good, and metal bullet lamella 30 then can adopt 65Mn material or the elasticity that the performance is close with 65Mn material is good, the material of tensile strength carries out the punching press and forms, good elasticity can be guaranteed to buckle the screen to LED and also can kick-back original planar state after buckling, high tensile strength can improve the LED by a wide margin and buckle the hoist and mount height and the hoist and mount security of screen in the integral hoisting in-process.

step S20: splicing a plurality of LED face covers adjacently, installing a plurality of LED modules 220 on the LED face covers, and enabling the interval gaps between two adjacent LED modules 220 to be arranged in one-to-one correspondence with the bending grooves 101 on the LED face covers, so as to form an LED screen;

step S30: and bending the assembled LED screen to form the LED bent screen in the target shape.

By applying the design method of the technical scheme to design the LED bending screen, each relative rotating shaft and the display surface of the LED bending screen in the bending process are positioned on the same surface, so that the problem that the distance between two adjacent LED modules 220 exceeds +/-5% of the standard distance due to the fact that the two adjacent LED modules 220 rotate relative to the rotating shaft to form the bending display surface can be solved to the greatest extent, and the display effect is influenced due to the fact that obvious dark lines or bright lines appear on an image displayed on the screen. Meanwhile, the designed LED mask is used for effectively protecting the LED module 220, and the LED mask using the metal elastic sheet layer 30 has better bending elasticity and tensile strength compared with the masks in the prior art.
