Illustratively, the back cover 121 includes a first side wall 1213, a second side wall 1214, a top wall 1215, and a bottom wall 1216. The first side wall 1213, the second side wall 1214, the top wall 1215, and the bottom wall 1216 enclose a receiving slot 1211. The first side wall 1213 and the second side wall 1214 are disposed opposite each other, the top wall 1215 and the bottom wall 1216 are disposed opposite each other, and the top wall 1215 connects the first side wall 1213 and the second side wall 1214, and the bottom wall 1216 connects the first side wall 1213 and the second side wall 1214. The bottom wall 1216 is attached to the light board 11, for example, may be adhered to the light board 11 by using glue, but may also be attached by a manner such as a snap-fit connection, which is only illustrated herein, and should not be construed as limiting the connection relationship between the bottom wall 1216 and the light board 11.

For convenience of description, the display module 10 is limited to three directions, that is, the length direction X, the width direction Y, and the height direction Z of the display module 10, and the length direction X, the width direction Y, and the height direction Z are perpendicular to each other.

The bottom wall 1216 is provided with a mounting opening 1217 to expose the power connection terminal 110 on the lamp panel 11 after the bottom wall 1216 is connected with the lamp panel 11. It should be noted that, the power connection end 110 is a connection port for electrically connecting the LED lamp beads on the lamp panel 11 with the power supply 13, the power connection end 110 may have a plurality of power connection ends 110, and the plurality of power connection ends 110 may be arranged at intervals along the length direction X of the display module 10 so as to adapt to the electrical connection of the LED lamp beads in different areas. The rear cover 121 is disposed on the lamp panel 11, and can cover a plurality of power connection terminals 110, so that on one hand, the connection between the power supply 13 and the power connection terminals 110 can be facilitated, and on the other hand, the power connection terminals 110 can be protected from being affected by external water vapor, and the safety of the display module 10 is improved.

It is understood that the rear cover 121 or the power box 12 may have an elongated shape, that is, the rear cover 121 or the power box 12 extends along the length direction X of the display module 10 so as to cover the power connection terminal 110.

In the width direction Y of the display module 10, the width of the power box 12 formed by the rear cover 121 and the cover 122 is smaller than the width of the lamp panel 11, so that the size of the power box 12 can be reduced, and the material cost can be further saved. In addition, the power box 12 can be arranged in the middle area of the lamp panel 11, so that the lamp panel 11 is stressed uniformly, and the situation that the lamp panel 11 is crushed due to stress deflection is reduced. For example, the lamp panel 11 has a middle region 111, edge regions 112 disposed at opposite sides of the middle region 111 in the width direction Y of the display module 10, and the rear cover 121 is disposed at the middle region 111. Wherein the width of the edge regions 112 disposed at opposite sides of the middle region 111 in the width direction Y of the display module 10 may be equal, and the width of each edge region 112 is greater than the width of the middle region 111 to accommodate the installation of the rear cover 121 and to facilitate the arrangement of the power connection terminals 110.

The plurality of positions of the openings 1210 may be different from each other, and the relative positional relationship between the cover 122 and the rear cover 121 is different from each other.

In the first case, the opening 1210 is disposed on the first side wall 1213 or the second side wall 1214, that is, the opening 1210 faces the width direction Y of the display module 10, and the extending direction of the opening 1210 faces the length direction X of the display module 10. For example, the opening 1210 is provided in the first side wall 1213, that is, is perforated from the first side wall 1213, and the power source 13 abuts against the second side wall 1214 in a state where the cover 122 is connected to the rear cover 121. Thus, the power supply 13 has at least two heat dissipation surfaces of the cover 122 and the second side wall 1214, and the heat dissipation area and the heat dissipation efficiency can be increased compared to the prior art having only one contact surface. Similarly, the opening 1210 may be provided on the second side wall 1214, and the power source 13 may be in contact with the first side wall 1213 in a state where the cover 122 is connected to the rear cover 121. Thus, the power supply 13 has at least two heat radiating surfaces of the cover 122 and the first side wall 1213, and the heat radiating area and the heat radiating efficiency can be increased compared to the conventional art which has only one contact surface.

Referring to fig. 1 to 7 in combination with fig. 8 and 9, fig. 8 is a schematic diagram of an explosion structure of a power box and a power source provided in an embodiment of the present application, and fig. 9 is a schematic diagram of a cross-sectional structure of the power box and the power source provided in the embodiment of the present application. In this case, a first distance L1 is provided between the power supply 13 and the top wall 1215, and a second distance L2 is provided between the power supply 13 and the lamp panel 11, where the second distance L2 is greater than or equal to the first distance L1, so that the power supply 13 is as far away from the lamp panel 11 as possible, and the influence on the LED lamp beads on the lamp panel 11 is reduced; meanwhile, a first distance L1 is arranged between the power supply 13 and the top wall 1215, so that on one hand, the blocking of components in the installation process can be reduced, and the installation of the power supply 13 is convenient; on the other hand, space may be provided for the connection of the cover 122 to the rear cover 121.

In other words, in the height direction Z of the display module 10, the height of the power source 13 is smaller than or equal to the height of the cover 122, and the height of the cover 122 is smaller than the height of the side wall of the opening 1210, that is, the power source 13 is not affected to be placed in the rear cover 121, so that the power source 13 is convenient to be installed, and a space can be provided for connecting the cover 122 with the rear cover 121.

In the length direction X of the display module 10, the length of the power source 13 is smaller than the length of the cover 122, and the length of the cover 122 is smaller than the length of the sidewall of the opening 1210. Setting the length of the cover 122 to be greater than the length of the power supply 13 can improve the load bearing capacity of the cover 122 and improve the mounting fastness of the power supply 13. Positioning and connection with the rear cover 121 can be facilitated by setting the length of the cover 122 to be smaller than the length of the sidewall where the opening 1210 is located.

The power source 13 may be provided with a middle section 1220, and the edge section 1221 is used for connection, so that the stress of the cover 122 is balanced, and the connection stability and the firmness are improved.

The display module 10 further includes a first heat conducting member 14 and/or a second heat conducting member 15, where the first heat conducting member 14 is disposed between the power source 13 and the cover 122 to help transfer heat from the power source 13 to the cover 122 and dissipate heat through the cover 122. The second heat conductive member 15 is disposed between the power source 13 and a sidewall of the rear cover 121 abutting against the power source 13 to help transfer heat of the power source 13 to the rear cover 121 and then dissipate the heat through the rear cover 121. In actual use, it is optional to provide only the first heat conductive member 14, or only the second heat conductive member 15. In this embodiment, the first heat conducting member 14 and the second heat conducting member 15 are respectively disposed on two opposite sides of the power supply 13 for illustration, so that heat transfer efficiency can be improved, and heat dissipation efficiency can be further improved.

In some embodiments, a heat-conducting silica gel may be disposed between the power source 13 and the top wall 1215, so that heat of the power source 13 may be transferred and dissipated through three parts of the cover 122, the side wall of the rear cover 121, and the top wall 1215, and the heat dissipation area is large and the heat dissipation efficiency is high.

In the second case, the opening 1210 is provided on the top wall 1215 (not shown), the cover 122 is connected to the top wall 1215, the power source 13 is mounted on the cover 122, and the power source 13 is respectively abutted against the first side wall 1213 and the second side wall 1214, so that the power source 13 has three contact surfaces of the first side wall 1213, the second side wall 1214 and the cover 122, and the heat dissipation area of the power source 13 is increased, thereby increasing the heat dissipation efficiency.

Among them, the heat conductive silica gel may be disposed between the power source 13 and the rear cover 121 and the cover 122, and the description in the first case may be referred to specifically, which will not be repeated here.
