Refer to FIG. 1, which is a schematic structural diagram of an embodiment of an LED display screen of the present application. The LED display screen 100 includes a substrate 30, a light-shielding frame 10 and an optical film 20.

The substrate 30 is provided with LED light-emitting units distributed in an array, the optical film 20 is fixed on a surface of the light-shielding frame 10, and the light-shielding frame 10 is arranged on the light emitting path of the LED light-emitting unit. The light-shielding frame 10 includes a plurality of grids 11 distributed in an array. To accommodate the corresponding LED lighting unit. In other words, the light-shielding frame 10 is located between the substrate 30 and the optical film 20, and the LED light-emitting units distributed in an array on the substrate 30 are accommodated in the grids 11 of the light-shielding frame 10, so that each grid 11 contains LED light-emitting units. Form a pixel of the LED display screen. A plurality of first fixing members are provided on the side adjacent to the base plate 30 of the grid 11, and the first fixing members may be fasteners, fasteners, or fixing holes. The area of the base plate 30 corresponding to the first fixing member is provided with a second fixing member, and the second fixing member may be a through fixing hole or a fastener. The first fixing member and the second fixing member cooperate to fix the light shielding frame 10 and the base plate 30. The substrate 30 may be a metal plate or a printed circuit board (Printed Circuit Board), etc., and an LED light emitting unit may be provided on the substrate 30 through surface mounting or COB (Chips on Board) packaging. The multiple grids 11 distributed in the array of the light-shielding frame 10 are used for accommodating the LED light-emitting units, so that the array-distributed LED light-emitting units can be separated to prevent optical crosstalk between the LED light-emitting units. The material of the light-shielding frame 10 may be one or more of plastic, plastic, metal, or metal alloy. The shape of the light-shielding frame 10 may be rectangular, square, circular, etc., which can be specifically set according to actual conditions, and is not limited here. The optical film 20 may be one of a diffusion film, a polarizing film, or a protective film. The fixing method of the optical film 20 may be bonding, clamping, or using a clamp, which is not limited here.

By fixing the optical film 20 on one surface of the light-shielding frame 10, the other surface of the light-shielding frame 10 is fixed on the substrate 30 to separate the LED light-emitting units distributed in the array. Therefore, the optical crosstalk between the LED light-emitting units on the substrate 30 can be reduced, and the display effect of the LED display screen 100 can be improved through the optical film 20. In addition, the method of assembling the inner surface of the shading frame 10 with the substrate 30 further reduces the installation traces of the assembly, so that when the LED display screen 100 is viewed from the front, the appearance of the appearance is not affected by the installation traces.

Optionally, referring to FIG. 2, the thickness of the shading frame 10 is 0.1-10 mm. It can be understood that when the substrate 30, the light-shielding frame 10 and the optical film 20 are fixed, the distance between the optical film 20 and the substrate 30 is the thickness of the light-shielding frame 10, thereby leaving space for accommodating the LED light-emitting unit. It is avoided that the optical film 20 is pressed against the LED light-emitting unit, causing damage to the LED light-emitting unit.

Referring to FIG. 3, the light shielding frame 10 may include a first grid 12 and a second grid 13. The first grid 12 and the second grid 13 are staggered to form a plurality of grids 11 distributed in an array on the light shielding frame 10. Among them, the space of each grid 11 can accommodate one or two or three LED light-emitting units, so that each space corresponds to one pixel of the LED display screen 100. The shape and number of the grid 11 are not limited here. For example, it may be a seamlessly spliced quadrilateral or a seamlessly spliced hexagon, and the number may be 64, 81, or 255. The thickness of the first grid 12 and the second grid 13 of the light shielding frame 10 are the same. That is, the width W1 of the first grid 12 and the width W2 of the second grid 13 are equal, and the thickness value may be 0.2-5 mm.

Optionally, with reference to FIGS. 4 and 5, the first fixing member may include a fastener 40 integrally formed with the light-shielding frame 10, and the second fixing member is a through hole corresponding to the fastener 40, and the fastener 40 is connected to the base plate. The through holes of 30 are assembled by interference. The fastener 40 may be a polyhedron (such as a rectangular parallelepiped, etc.) or a rotating body (such as a truncated cone or a cone) composed of elastic materials such as plastic or plastic. The number of fasteners 40 may be 4, 5, 9, etc. The plurality of fasteners 40 may be evenly distributed in the center, the four corners, and the center positions of the four sides of the light-shielding frame 10 and face one side of the substrate 30. Specifically, the fastener 40 may be arranged on the first grid 12 or the second grid 13 or at the intersection of the first grid 12 and the second grid 13, preferably at the intersection.

Continuing to refer to FIG. 4, the fastener 40 may include a first structure 41 and a second structure 42. One end of the first structure 41 is connected to the light shielding frame 10, and the second structure 42 is stacked on the other end of the first structure 41. Optionally, the first structure 41 is one of a frustum, a cylinder, or a cone, and the second structure 42 is one of a frustum, a cone, or a cylinder. For example, the fastener 40 may be integrally formed and the first structure 41 located at the intersection of the first grid 12 and the second grid 13 is a combined structure of a cylinder and the second structure 42 is a truncated cone. The height h1 of the cylinder can be 0.1-3 mm. The diameter D1 of the cylinder may be 0.2-5 mm. The diameter of the cylinder may be greater than the width W1 of the first grid 12 or the width W2 of the second grid 13. The height h2 of the truncated cone can be less than or equal to the height h1 of the cylinder, and the diameter D2 of the truncated cone can be less than the diameter D1 of the cylinder. As shown in (a) and (b) of FIG. 5, the second fixing member in the corresponding area on the substrate 30 may be a through hole, the diameter of the through hole may be D3, and the second structure 42 is that the diameter D2 of the truncated cone is smaller than the through hole. The diameter D3 of the hole facilitates the insertion of the fastener 40 into the through hole. Since the tolerance zone of the cylinder of the first structure 41 is larger than the tolerance zone of the through hole, and the fastener 40 is usually made of elastic materials such as plastics, plastics, etc., a slight force during installation can press the fastener 40 into the through hole of the substrate 30. In the hole, the elastic deformation of the fastener 40 will increase the friction force between the fastener 40 and the substrate 30, so that the light shielding frame 10 can be fixed on the substrate 30. The fastener 40 can be completely inserted into the through hole of the substrate 30, so that the fastener 40 can prevent the fastener 40 from affecting the light shielding effect of the light shielding frame 10. In other embodiments, the second fixing member provided on the base plate 30 is an integrally formed fastener 40, and the first fixing member provided on the shading frame 10 is a fixing hole, and the two are fixed by interference fit.

The height and diameter of the cylinder 41a and the cone 42a may be similar to those of the previous embodiments, and will not be repeated here. Since the cone 42a will be provided on the cylinder 41a, it is advantageous for the fastener 40 to penetrate into the through hole of the base plate 30, and the assembly efficiency of the light shielding frame 10 and the base plate 30 is improved. Referring to FIG. 7, the fastener 40 may be a stepped body formed by the combination of the structure 41b and the structure 42b. The structure 41b and the structure 42b may both be polyhedrons (such as cuboid) or rotating bodies (such as cylinders). The heights of the

structures

41b and 42b Similar to the previous embodiment, the radial width of the structure 41b is greater than the radial width of the structure 42b.

Referring to FIG. 8, the outer surface of the first structure 41 c of the fastener 40 may be provided with a convex elastic body 43 to further increase the friction. The elastic body 43 may be made of the same material as the fastener 40, for example, rubber or elastic plastic. The fastener 40 can be a combination of a cylinder 41c and a truncated cone 42c. The difference from the previous embodiment is that in this embodiment, the outer surface of the cylinder 41c is circumferentially provided with a convex elastic body 43, so that when the cylinder 41c fits with the hole When fixing, the elastic body 43 further enhances the friction between the fastener 40 and the inner wall of the hole of the base plate 30, thereby making the assembly and fixing between the light shielding frame 10 and the base plate 30 stronger. Referring to Fig. 9, the fastener 40 may be an integral round table 41d. That is, the second structure 42 is removed and the first structure 41 is directly integrated. At this time, the height of the round table 41d is the sum of the height of the cylinder 41 and the round table 42 in the previous embodiment. In addition, a convex elastic body 43 is provided in the circumferential direction of the outer surface of the end of the round table 42. When the round table 41d is fitted and fixed with the through hole of the substrate 30, the elastic body 43 can further enhance the friction between the first fixing member and the inner wall of the through hole of the substrate 30, reduce the risk of the shading frame 10 falling off the substrate 30, and save The removal of the cylindrical part makes the production of the fastener 40 easier and saves the production cost. Of course, the fastener 40 can also be a separate cylindrical structure (not shown in the figure). At this time, the height of the cylinder is the sum of the heights of the cylinder 41 and the truncated cone 42 in the previous embodiment, and is arranged circumferentially on the outer surface of the end of the cylinder.

In this embodiment, the outer surface of the cylinder 41c may be provided with grooves to form a threaded structure. Corresponding threaded holes can be provided on the base plate 30. It can be understood that the fastener 40 and the base plate 30 are fixed by thread matching, so that the fixing of the fastener 40 and the base plate 30 is stronger.

In some embodiments, referring to FIG. 11, the first fixing member of the light-shielding frame 10 may include an integrally formed fastener 50, and the fastener 50 may be composed of plastic or elastic materials such as plastic. The second fixing member is a through hole corresponding to the buckle 50, and the buckle 50 and the through hole are assembled by a snap fit so that the light shielding frame 10 is fixed to the substrate 30. The plurality of fasteners 50 can be evenly distributed in the center, the four corners and the center positions of the four sides of the light-shielding frame 10 and face one side of the substrate 30. Specifically, the buckle 50 may be arranged on the first grille 12 or the second grille 13 or at the intersection of the first grille 12 and the second grille 13, preferably at the intersection. The buckle 50 may include a support portion 51 and a buckle portion 52 formed integrally, and the bottom diameter of the support portion 51 may be 0.2-8 mm. The buckle part 52 may be a hollow circular truncated cone structure, the bottom diameter of the truncated cone is larger than the bottom diameter of the support part 51, and the top diameter of the truncated cone can be between the bottom diameter of the support part 51 and the bottom diameter of itself, so as to facilitate the insertion of the buckle 50. Continuing to refer to (a) and (b) in Fig. 12, the base plate 30 may be provided with a through hole matching the fastener 50. When the fastener 50 is not subject to external force, the diameter of the bottom of the truncated cone of the fastener 52 is larger than The diameter of the through hole, when the buckle 50 receives an external force, the diameter of the bottom of the buckle part 52 is smaller than the diameter of the through hole. When the buckle part 52 completely penetrates the through hole, due to its own elasticity, the buckle part 52 The diameter is greater than the diameter of the through hole. At this time, the fastener 50 is locked on the side of the substrate 30 away from the light shielding frame 10. The height of the support portion 51 may be the same as the thickness of the substrate 30, so that the fastener 50 is firmly clamped in the through hole, and the fastener 50 is prevented from loosening.

Specifically, the first fixing hole 60 may be provided on the first grill 12 or the second grill 13 or at the intersection of the first grill 12 and the second grill 13, preferably at the intersection. The first fixing hole 60 can be used to receive the screw 61 and screw it to fix the light-shielding frame 10 and the substrate 30. When assembling, the screw 61 can pass through the second fixing hole of the substrate 30 from the side of the substrate 30 away from the light-shielding frame 10 to the first fixing hole 60 on the light-shielding frame 10, so as to realize the fixation. Refer to Figure 16. The above method can prevent the screw 61 from being exposed on the surface of the light-shielding frame 10, thereby ensuring the uniformity of the appearance of the light-shielding frame 10, and avoiding the screw from affecting the display of the LED display screen 100. Of course, other types of screws (bolts) can also be used to pass through the second fixing hole of the substrate 30 from the side of the substrate 30 away from the light-shielding frame 10 to the first fixing hole 60 on the light-shielding frame 10, and fix it by screwing. .
