Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, an LED display panel mainly includes a panel body 11, a display module 12 provided on the panel body, and a plug panel 13 provided on the back of the panel body.

The panel body 11 includes an integrally formed aluminum plate 111, and a sealing member 112 inserted into the aluminum plate 111 and penetrating through the two openings.

As shown in fig. 3, the aluminum plate 111 further includes a mounting plate 1111 and a heat insulation plate 1112 arranged at intervals, two end plates 1113 connecting the mounting plate 1111 and the end of the heat insulation plate 1112, and three support ribs 1114 connecting the mounting plate 1111 and the interior of the heat insulation plate 1112. Further, the both ends and the middle part on mounting panel 1111 surface are provided with a spacing groove 1115 respectively, be used for setting up mounting such as plastic strip in the spacing groove 1115 for the cooperation screw is fixed in display module 12 on mounting panel 1111, in order to avoid additionally punching on the mounting panel, and because the mounting panel is thinner, will come direct fixation screw through punching, stability is not good. The limiting groove 1115 has a structure with a narrow opening and a wide inner portion, so as to ensure the position stability of the plastic strip inside the limiting groove. Two sides of the surface of the mounting plate 1111 are further respectively provided with an avoidance groove 1117 for avoiding elements such as a capacitor in the display module 12, so as to reduce the thickness of the whole LED display panel as much as possible.

The arrangement of the heat insulation plate 1112 enables a heat insulation and flow guide cavity 1118 to be formed between the heat insulation plate 1112 and the mounting plate 1111, on one hand, the mounting plate 1111 absorbs heat generated by the display assembly 12 and discharges the heat into the heat insulation and flow guide cavity 1118, and efficient heat dissipation is performed through convection action formed among a plurality of heat dissipation holes arranged on the opposite side surfaces of the panel main body; on the other hand, when the display screen is used outdoors, due to the direct radiation of sunlight, the temperature of the heat insulation plate 1112 is too high, and the heat insulation diversion cavity 1118 effectively prevents the heat on the heat insulation plate 1112 from directly acting on the mounting plate 1111 and the display component 12, that is, the heat insulation diversion cavity 1118 is also utilized for efficient heat dissipation.

Three brace bars 1114 locate two grooves 1117 of dodging respectively, and a spacing groove 1115 department at middle part, on the one hand directly utilize the structural strength who dodges groove 1117 and spacing groove 1115, on the other hand has shortened the length of brace bar 1114 on mounting panel 1111 and heat insulating board 1112 connected direction to improve the structural strength of brace bar self, thereby improved the support strength between mounting panel 1111 and heat insulating board 1112, ensure the stability of distance between the two, prevent to warp.
