[0049] As shown in FIG. 1, Figures 1 to 13 The display module provided by the embodiments of the present application extends the brim 122 away from the lamp panel 110, and the brim 122 can shield the light emitted upward by the lamp beads 113 on the lamp panel 110, that is, the upward viewing angle of the lamp panel 110 can be shielded. In this way, the upward light emission of the lamp panel 110 can be shielded without affecting the crowd below the lamp panel 110 to view the lamp panel 110, and the application scenarios of the lamp panel 110 can be increased, and the display module can be conveniently used as an outdoor display in an airport or other specific places.

[0050] The display module provided by the embodiments of the present application extends the brim 122 away from the lamp panel 110, and the brim 122 can shield the light emitted upward by the lamp beads 113 on the lamp panel 110, that is, the upward viewing angle of the lamp panel 110 can be shielded. In this way, the upward light emission of the lamp panel 110 can be shielded without affecting the crowd below the lamp panel 110 to view the lamp panel 110, and the application scenarios of the lamp panel 110 can be increased, and the display module can be conveniently used as an outdoor display in an airport or other specific places.

[0051] The display module provided in the embodiment of the present application comprises a lamp panel 110 and a mask 120, the mask 120 comprises a cover body 121 and a brim 122, the cover body 121 and the brim 122 are integrated, in use, the lamp panel 110 is used for displaying pictures or videos, and the cover body 121 is connected to the lamp panel 110, in the first aspect, the cover body 121 can protect the lamp panel 110, especially the lamp beads 113 on the lamp panel 110, in the second aspect, the cover body 121 can shield the gap on the lamp panel 110, when the lamp panel 110 is turned on, the light leakage of the display module can be reduced, the display brightness and contrast can be improved, when the lamp panel 110 is turned off, the appearance of the lamp panel 110 as a whole can be black, the light leakage is eliminated, and the display module can be more beautiful.

[0052] The display module provided in the embodiment of the present application is integrated by the brim 122 and the cover body 121, when the cover body 121 is assembled on the lamp panel 110, the installation of the brim 122 can be completed synchronously, the assembly efficiency is higher, the cover body 121 and the brim 122 can be prepared synchronously by the injection molding process, the preparation and assembly costs can be reduced, the mechanical strength of the cover body 121 and the brim 122 can be guaranteed, and the service life of the display module can be improved.

[0053] The display module provided in the embodiment of the present application is integrated by the brim 122 and the cover body 121, when the cover body 121 is assembled on the lamp panel 110, the installation of the brim 122 can be completed synchronously, the assembly efficiency is higher, the cover body 121 and the brim 122 can be prepared synchronously by the injection molding process, the preparation and assembly costs can be reduced, the mechanical strength of the cover body 121 and the brim 122 can be guaranteed, and the service life of the display module can be improved.

[0054] It can be understood that the lamp panel 110 can emit light through the lamp beads 113, such as emitting light through the LED lamp beads 113, and the brim 122 at least shields the upper viewing angle of the lamp panel 110, that is, the light emitted upward by the lamp beads 113 can be shielded.

[0055] As shown in Figure 3 In a feasible implementation, the lamp panel 110 comprises: a circuit board 112, the circuit board 112 is connected to the cover body 121; a plurality of lamp beads 113, the lamp beads 113 are connected to the circuit board 112, a gap is formed between two adjacent rows of lamp beads 113, and the cover body 121 is used for covering the gap.

[0056] In the technical solution, the structure of the lamp panel 110 is further provided, and the lamp panel 110 can include a circuit board 112 and lamp beads 113. The circuit board 112 provides a mounting position for the lamp beads 113. The lamp beads 113 can be arranged in an array on the circuit board 112. By controlling the light emission of each lamp bead 113, the lamp panel 110 can display the expected image. By covering the gap between the adjacent two rows of lamp beads 113 by the cover 121, in the first aspect, the cover 121 can protect the lamp beads 113. In the second aspect, the cover 121 can cover the gap above the lamp panel 110. When the lamp panel 110 is turned on, the light leakage of the display module can be reduced. When the lamp panel 110 is turned off, the overall appearance of the lamp panel 110 can be black, thereby improving the display brightness and contrast.

[0057] As shown in Figures 1 to 11 In a feasible implementation, the shortest distance from the free end of the brim 122 to the lamp panel 110 is 12 cm to 20 cm.

[0058] In the technical solution, the relationship between the brim 122 and the lamp panel 110 is further provided. The shortest distance from the free end of the brim 122 to the lamp panel 110 is 12 cm to 20 cm, that is, the vertical distance between the free end of the brim 122 and the lamp panel 110 can be 12 cm to 20 cm. Based on this, the shielding range of the brim 122 to the upward viewing angle can be controlled. The user located below the display module can watch the display range of the lamp panel 110 while shielding the upward viewing angle as much as possible to increase the applicable scenarios of the display module. It can be understood that the longer the brim 122 is, the greater the shielding range to the upward viewing angle will be. Conversely, the shorter the brim 122 is, the smaller the shielding angle to the upward viewing angle will be. When the shortest distance between the brim 122 and the lamp panel 110 is less than 12 cm, the angle shielding to the upward viewing angle will be small. In this case, when the display module emits light, the light will still affect the normal work of the aircraft. When the shortest distance between the brim 122 and the display module is greater than 20 cm, the brim 122 will shield the light emission of the lamp panel 110 too much, and the visible range of the lamp panel 110 will be reduced.

[0059] As shown in Figures 1 to 11 In a feasible implementation, the shortest distance from the free end of the brim 122 to the lamp panel 110 is determined by the following formula:

[0060] Hm=(d / 2)tan(Sθ)

[0061] Wherein, Hm is the shortest distance from the free end of the brim 122 to the lamp panel 110, d is the height of the light-emitting area of the lamp bead, and Sθ is the upward viewing angle of the lamp bead.

[0062] In the technical solution, the specific relationship between the effective length of the brim 122 and other parameters of the screen module is further provided, the shortest distance between the brim 122 and the lamp panel 110 can be determined based on the height of the light-emitting area and the upper viewing angle, and the height of the light-emitting area is determined by the properties of the lamp beads 113. After the size and internal structure of the lamp beads 113 are determined, the height of the light-emitting area is a known quantity, and the upper viewing angle can be determined based on the actual use scenario of the display module. For example, in the use scenario of an airport, the upper viewing angle of the display module generally does not exceed 3°. Based on this, the style of the brim 122 can be determined based on the user's requirements and the selection of the lamp beads 113, which facilitates the preparation of the brim 122 and ensures that the brim 122 can achieve the expected shielding effect.

[0063] As shown in Figures 1 to 11 In a possible implementation, the included angle between the central axis of the brim 122 and the side surface 114 of the lamp panel 110 is 7° to 12°. Specifically, the included angle can be 7°, 8°, 9°, 10°, 11°, or 12°, or a non-integer value in the range.

[0064] In a possible implementation, the included angle between the central axis of the brim 122 and the side surface 114 of the lamp panel 110 is determined by the following formula:

[0065] tan(Cθ)=Mj / Hm

[0066] Wherein, Cθ is the included angle between the central axis of the brim 122 and the side surface 114 of the lamp panel 110, Mj is the distance between the intersection point and the center of the lamp bead 113, the intersection point is the lowest point of the free end of the brim 122 along the straight line parallel to the central axis and the intersection point formed with the lamp panel 110, and Hm is the shortest distance from the free end of the brim 122 to the lamp panel 110.

[0067] In the technical solution, the relationship between the structure parameters of the brim 122 and the lamp panel 110 is further provided, and the included angle between the central axis of the brim 122 and the side surface 114 of the lamp panel 110 can be determined based on Mj and Hm, so that the brim 122 can better shield the upper viewing angle.

[0068] In some examples, the distance Mj between the intersection point and the center of the lamp bead 113 is determined by the following formula: Mj=M / 2+A, wherein M is the distance from the side surface of the lamp panel 110 to the center of the first row of lamp beads 113, and A is an offset constant. The value of the offset constant A can be -5mm to 5mm, for example, -5mm, -4mm, -3mm, -2mm, -1mm, 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, and preferably 1mm. Based on this, the included angle between the central axis of the brim 122 and the side surface of the lamp panel 110 can be determined, so that the preparation of the display module is more convenient.

[0069] In some examples, at least one of the profile lines on the upper and lower sides of the brim 122 has an included angle with the central axis of the brim 122, and the included angle is the draft angle of the brim 122, which can be 1° to 5°, for example, 1°, 2°, 3°, 4°, or 5°. In this technical solution, considering that in order to make the display module applicable to some special use scenarios, the brim 122 usually has a certain length, and in this case, there will be a certain demolding difficulty when the brim 122 and the cover 121 are prepared by the injection molding process. Based on the fact that at least one of the profile lines on the upper and lower sides of the brim 122 has an included angle with the central axis of the brim 122, and the included angle is 1° to 5°, the brim 122 has a certain demolding angle, which can make the brim 122 demold better and facilitate the preparation of the integrated structure of the brim 122 and the cover 121.

[0070] As shown in Figures 1 to 11 In a feasible implementation, the display module further includes a lower viewing angle shielding piece 130, and the lower viewing angle shielding piece 130 is in an integrated structure with the cover 121.

[0071] In this technical solution, in addition to the brim 122 for shielding the upper viewing angle, the display module can further include the lower viewing angle shielding piece 130. Based on this, the lower viewing angle shielding piece 130 can shield the lower viewing angle of the lamp panel 110, which can make the image light of the lamp panel 110 observed by the user more uniform, can avoid excessive gathering of light, and can improve the viewing effect.

[0072] In a feasible implementation, the lamp panel further includes a shell 111, and the shell 111 is installed on the surface of the lamp panel 110 away from the cover 121. In this way, the shell 111 provides a mounting position for the circuit board 112, and the circuit board 112 can be included through the shell 111.

[0073] In a feasible implementation, the cover 121 and the brim 122 are an integrally formed structure prepared by an injection molding process.

[0074] In this technical solution, a specific preparation process of the cover 121 and the brim 122 is further provided, and the cover 121 and the brim 122 are an integrally formed structure prepared by an injection molding process, which can further reduce the cost of the display module while ensuring the processing precision of the cover 121 and the brim 122.

[0075] In a feasible implementation, a groove is formed on the lamp panel 110, a hook is formed on the cover 121, and the cover 121 is connected to the lamp panel 110 through the hook and the groove.

[0076] In the technical scheme, a hook is arranged on the cover body 121, a groove is reserved on the circuit board 112 of the lamp panel 110, and the cover body 121 is connected to the lamp panel 110 by the hooking manner, so that the connection of the cover body 121 and the brim 122 is more convenient.

[0077] In an available embodiment, the mask 120 is connected to the lamp panel 110 by a fastener.

[0078] In the technical scheme, another connection manner of the mask 120 and the lamp panel 110 is provided, the mask 120 can be locked on the lamp panel 110 by a fastener, for example, a screw hole is reserved on the circuit board 112, and the cover body 121 is fixed by screwing a screw through the cover body 121 into the screw hole.

[0079] Embodiment

[0080] As shown in Figures 1 to 11 , the embodiment of the present application provides a display module, which comprises a lamp panel 110 having a side surface 114, and a mask 120 comprising a cover body 121 and a brim 122, the cover body 121 being connected to the lamp panel 110, the brim 122 being an integral structure with the cover body 121, the brim 122 extending away from the lamp panel 110, the brim 122 being arranged at an acute angle with the side surface of the lamp panel 110, so as to shield the upward viewing angle of the lamp panel 110.

[0081] As shown in Figure 12 and Figure 13 , the parameters of the brim 122 and the lamp panel 110 satisfy the following formula:

[0082] Hm=(d / 2)tan(Sθ)

[0083] tan(Cθ)=Mj / Hm

[0084] tan(Xθ)=P / Hm

[0085] Lmin=Hp / tan(Xθ)

[0086] Lmax=Hp / tan(Sθ)

[0087] Wherein, Hm is the shortest distance from the free end of the brim 122 to the lamp panel 110, d is the height of the light-emitting area of the lamp bead, Sθ is the upper viewing angle of the lamp bead, Cθ is the angle between the central axis of the brim 122 and the side surface 114 of the lamp panel 110, Mj is the distance between the intersection and the center of the lamp bead, the intersection is the lowest point of the free end of the brim, and the intersection is formed along a straight line parallel to the central axis and the lamp panel, Lmin is the distance from the imageless area to the display module, Hp is the distance between the display module and the ground, Xθ is the lower viewing angle, Lmax is the distance from the image area to the imageless area, and P is the pitch of the lamp bead 113. It can be understood that in actual production, d, Xθ, Sθ, P, Hp and Mj are known parameters, Xθ and Sθ are the lower viewing angle and the upper viewing angle, which are determined by the use scene of the display module and customer demand, for example, the upper viewing angle of the display module in the airport is not more than 3°; P is the pitch of the lamp bead 113, also called point pitch, which is determined by the use scene, customer demand, etc.; Hp is the height of the screen body from the ground, which can be determined after the screen body is installed; Mj is the distance from the extension line of the brim 122 to the center of the LED lamp bead 113, which can be half of the distance from the side surface of the lamp panel 110 to the center of the first row of lamp beads 113, and can be offset by a certain value (for example, within 5mm, generally about 1mm) up and down.

[0088] The display module provided by the embodiments of the present application considers that the special scene of the outdoor display module in the prior art needs to use a high brim cover, and the high brim of the existing cover can only be used for shading, and the shielding is limited. For example, when the plane takes off at the airport, the light source needs to be shielded, and a higher high brim cover needs to be used to shield the upper viewing angle. In order to enable the outdoor display module in the prior art to be used in the airport, the brim needs to be additionally installed on the display module, and the disassembly and assembly structure needs higher price (two structure parts) and labor cost (installation time). The cooperation tolerance of the two structure parts affects the overall flatness, etc. In order to install the two structure parts, more processes need to be increased, such as the need to design a buckle fixing and increase screw fixing, which increases the design cost and labor cost.

[0089] Based on this, the display module provided by the embodiment of the present application includes the lamp panel 110 and the mask 120, the mask 120 includes the cover body 121 and the brim 122 in an integrated structure, in the use process, the lamp panel 110 is used to show pictures or videos, and the cover body 121 is connected to the lamp panel 110, first, the cover body 121 can protect the lamp panel 110, especially the lamp beads 113 above the lamp panel 110; second, the gap above the lamp panel 110 can be shielded through the cover body 121, when the lamp panel 110 is turned on, the light leakage of the display module can be reduced, the display brightness and contrast can be improved, when the lamp panel 110 is turned off, the appearance of the lamp panel 110 as a whole can be black, the light leakage can be eliminated, and the display module can be more beautiful; and the brim 122 extends away from the lamp panel 110, the brim 122 can shield the light scattered upward by the lamp beads 113 on the lamp panel 110, that is, the upward viewing angle of the lamp panel 110 can be shielded, the upward light emission of the lamp panel 110 can be shielded without affecting the crowd below the lamp panel 110 to watch the lamp panel 110, the application scenarios of the lamp panel 110 can be increased, especially the display module can be conveniently used as an outdoor display in an airport or other specific places. In addition, the brim 122 and the cover body 121 are in an integrated structure, when the cover body 121 is assembled on the lamp panel 110, the installation of the brim 122 can be completed synchronously, the assembly efficiency is higher, the cover body 121 and the brim 122 can be prepared synchronously through the injection molding process, the preparation and assembly costs can be reduced, the mechanical strength of the cover body 121 and the brim 122 can be guaranteed, and the service life of the display module can be improved.

[0090] Further, considering that the brim 122 has a certain length and is prone to breakage during preparation, based on this, the specific style of the brim 122 is designed through the above formula, so that at least one of the profile lines on the upper and lower sides of the brim 122 has an angle with the central axis of the brim 122, and the angle can be used as a mold exit angle, so that the brim 122 can have sufficient height to meet the upward viewing angle shielding requirement, and the draft angle is appropriately increased on the basis of the mold exit direction, so that the cover body 121 can be integrally formed and taken out from the mold without breaking the brim 122 during the taking-out process due to the excessive height of the brim 122.
