Optionally, the internal input cable and the external output cord are interior equipped with power supply line and signal wire.
Optionally, the wire length of the internal input cable is greater than the wire length or described externally defeated of the external output cord
The wire length of cable is greater than the wire length of the internal input cable out.
Optionally, the LED box side be arranged a cable interface, with simultaneously draw the internal input cable and
The external output cord.
LED display provided by the utility model, the side of each LED box are equipped with internally input cable and right simultaneously
Outer output cord, internally input cable corresponding LED box is powered by branched line, current LED box it is internal
The external output cord that cable docks a upper LED box is inputted, the external output cord of current LED box docks next LED case
The internal input cable of body, to complete the cascade connection of each LED box in this LED display.As it can be seen that the technical program, each
The cascade connection of LED box is reduced interface quantity, is reduced cost, reduced in cabinet using the single-ended form for drawing both-end outlet
Portion's space hold.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the partial structural diagram of prior art LED display.
Fig. 2 is the partial structural diagram of LED display provided by the embodiment of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Fig. 2, the utility model embodiment provides a kind of LED display, which, which includes several, is in
The LED box 110 of matrix distribution, the side of each LED box 110 are equipped with internally input cable 120 and external output line simultaneously
Cable 130 internally inputs cable 120 and is powered by branched line 121 to corresponding LED box 110, current LED box 110
Internal input cable 120 to the external output cord 130 for connecting a LED box 110, the external output of current LED box 110
Cable 130 docks the internal input cable 120 of next LED box 110, to complete each LED box 110 in this LED display 100
Cascade connection.
In the present embodiment, as shown in Fig. 2, due to same LED box 110 internal input cable 120 and externally output
Cable 130 is set to the same side of LED box 110, as long as so that LED box 110 is arranged a cable interface and can draw simultaneously
