The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

Example one

The embodiment of the present disclosure discloses an LED display module 1, as shown in fig. 1 to 5, which includes a bottom case 11, a lamp panel 12, a first supporting portion 113, a second supporting portion 114, a first positioning portion 119, and a second positioning portion 115. The bottom case 11 includes a bottom plate 111 and side plates 112 surrounding the bottom plate 111 to form a hollow cylinder structure with one side open. The bottom plate 111 may be one of a rectangle, a square, or a circle, or may be another irregular shape, in the embodiment of the disclosure, the bottom plate 111 is a rectangle, and the side plates 112 are arranged around the outer edge of the bottom plate 111, so that the bottom case 11 is a rectangular column structure as a whole. Therefore, the finally assembled display screen is rectangular, the conventional appearance design of the display screen is met, and the universality is good.

Illustratively, the first supporting portion 113 is disposed on the bottom plate 111, the first supporting portion 113 is disposed in an annular shape, an outer annular surface of the first supporting portion 113 is attached to an inner wall surface of the side plate 112, the periphery of the lamp panel 12 is supported on the first supporting portion 113, when the lamp panel 12 is mounted on the bottom case 11, a mounting gap is formed between the lamp panel 12 and the first supporting portion 113 and between the lamp panel 12 and the side plate 112, and during pouring of the sealant, the sealant may leak from the mounting gap. Therefore, in consideration of the characteristics of the sealant, the sealant has a viscosity value of 1000 centipoise to 2500 centipoise, the larger the viscosity value is, the lower the fluidity is, the width L of the contact surface between the lamp panel 12 and the first supporting part 113 is at least 2mm in the application, in this case, even if the sealant with the viscosity value of 1000 centipoise is used for encapsulation, the flowing of the pouring sealant between the contact surfaces of the lamp panel 12 and the first supporting part is also seriously hindered, the fluidity is greatly reduced, even if a small amount of pouring sealant leaks, the design requirement can be met, and the pouring sealant deposited between the contact surfaces also plays a role of the sealant, so that the waterproof performance is further improved, the process of plugging the leaking sealant is not needed, the working efficiency and the product quality are improved, and the cost is reduced. In the embodiment of the present disclosure, in order to save the cost, the width L of the contact surface between the lamp panel 12 and the first supporting portion 113 may reach 2 mm.

For this reason, this application is when the design is made, can select to inwards extend first supporting part 113 and/or outwards extend lamp plate 12, thereby enlarge the contact surface width between first supporting part 113 and lamp plate 12, make the contact surface width be 2mm at least between lamp plate 12 and the first supporting part 113, thereby make the gluey mobility of the contact surface that flows into between lamp plate 12 and first supporting part 113 seriously reduce, so that can not continue to reveal to bottom plate 111 direction, thereby the leakage quantity of gluing has been reduced, avoid taking the process of gluing the stifled leakage to mend, the cost is practiced thrift and work efficiency has been improved. It is understood that the contact surface width L may be equal to the length and width of the lamp panel 12 minus half of the length and width of the inner ring of the first support portion 113.

Further, lamp plate 12 is the time of when the installation, and curb plate 112 is the protrusion setting in order to constitute first location portion 119 in the top of first supporting part 113 relatively, and first location portion 119 fixes a position lamp plate 12 all around, makes lamp plate 12 install inside drain pan 11. Simultaneously, the inner wall of first locating part 119 is relative with the lateral wall of lamp plate 12, and clearance H between the two is no more than 0.15 mm. Also considering the characteristics of the sealant, even if the sealant with a viscosity value of 1000 cp is used for encapsulation, the flow of the sealant in the gap H between the lamp panel 12 and the first positioning portion 119 of not more than 0.15mmd is seriously hindered, and the flow is greatly reduced. Even if a small amount of sealing glue flows out, the design requirement can be met, and the sealing glue deposited at the gap H also plays a role in sealing, so that the waterproof effect is further improved. In the embodiment of the present disclosure, for convenient positioning and installation, the gap H between the lamp panel 12 and the first positioning portion 119 may reach 0.15 mm.

It can be understood that the gap between the outer side wall of the lamp panel 12 and the inner wall of the first positioning portion 119 is equal to the value obtained by subtracting the value corresponding to the outer dimension of the lamp panel 12 from the inner dimension of the side panel 112. During manufacturing, the thickness of the wall of the first positioning portion 119 may be increased by extending the first positioning portion 119 inward, so that the gap between the first positioning portion 119 and the lamp panel 12 is not more than 0.15 mm. It is better to the reduction of gluing with the area of contact combined action that enlarges lamp plate 12 and first supporting part 113.

For example, as shown in fig. 3, when the lamp panel 12 is mounted on the bottom housing 11, in order to facilitate mounting, a positioning hole 121 is formed in the lamp panel 12, the bottom housing 11 is provided with a second positioning portion 115, the second positioning portion 115 is a column, and the positioning hole 121 is used for the second positioning portion 115 to pass through, so that when the lamp panel 12 is mounted, the second positioning portion 115 may be aligned with the positioning hole 121, and then the lamp panel 12 is mounted on the bottom housing 11 along the directions of the first positioning portion 119 and the second positioning portion 115.
