Fig. 2 is a kind of structural schematic diagram for LED display screen system that the embodiment of the present invention proposes.
Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Specific implementation mode be described in detail.
The following embodiments of the present invention propose a kind of new LED display screen system structure, in identical LED box specification,
Using this system structure, it can flexibly increase scanning card number in a LED box, reaching each LED lamp panel can be with
Cascade purpose is flexibly carried out, to obtain different screen body performance parameters to adapt to different occasions.
Specifically, referring to Fig. 2, the LED display screen system that the embodiment of the present invention proposes includes：Sending card 21, Hub plates 23,
Main scanning card 25, LED lamp panel 26, subscan card 27 and LED lamp panel 28；Each LED lamp panel 26 of the corresponding same Hub plates 23
And 28 be spliced into LED box and this LED box by connecting Hub plates 23 and be configured with main scanning card 25 and subscan card 27.Its
In, sending card 21 (is not painted such as DVI interface or HDMI interface typically via its video interface with head end video source in figure
Go out) connection, the vision signal of video source is converted into gigabit network interface or other transmit the signal format that faster interface supports,
The rear end of sending card 21 is for example connect via cable with main scanning card 25 by gigabit network interface；Main scanning card 25 and main scanning card 25
Between connected typically via cable.Main scanning card 25 has high-speed transmission interface output, main scanning card 25 and 27 energy of subscan card
It is connected by high-speed transmission interface, and high-speed transmission interface herein can be parallel interface, can also be serial line interface, and
And realize (namely main scanning card 25 and subscan in PCB (printed circuit board, printed circuit board) cabling form
It is formed and is electrically connected by PCB trace between card 27).Have on Hub plates 23 and the interface of multiple scanning cards is supported for example to arrange needle/mother row and connect
Mouthful；Furthermore there are one the interfaces for connecting main scanning card to be swept for auxiliary connection with one or more for such as setting on Hub plates 23
The interface of card is retouched, and can connect in cascaded fashion between each scanning card interface；Therefore, by connecting on Hub plates 23
Screen body performance parameter can be changed by connecing the scanning card of different number.In addition, there is enough lamp plate interfaces for example to arrange on Hub plates 23
Line interface is to connect LED lamp panel；As shown in Fig. 2, eight LED lamp panels 26 are cascaded by four lamp plate interfaces on Hub plates 23
Four go here and there and are electrically connected main scanning card 25, and eight LED lamp panels 28 are cascaded into four strings by the four additional lamp plate interface on Hub plates 23
And it is electrically connected subscan card 27.
It holds above-mentioned, when LED box performance parameter requires minimum, is for example only connected with main scanning card on Hub plates 23
25 without connecting subscan card 27, namely as the system structure scheme of Fig. 1.And it is more demanding in LED box performance parameter
When, it can be reduced by the way that subscan card 27 is connected to Hub plates 23 (namely adding subscan card 27 on Hub plates 23)
The cascade series of LED lamp panel, to improve screen body performance parameter.
More specifically, a subscan card 27 can be added on Hub plates 23, reach 2 times of pervious performance parameters；Also may be used
Performance parameter is further increased to add three subscan cards 27 on Hub plates 23, reaches original 4 times of performance parameter, with
Adapt to the scene of high request.
Major and minor scanning card is by whether have cable connection to carry out intelligent recognition, if scanning card has detected cable company
It connects, then the scanning card is main scanning card.Under main scanning card 25 receives the image data of entire LED box according to the parameter issued
Come, and is shown oneself needing image data to be shown to send to corresponding LED lamp panel 26；Furthermore 25, main scanning card
The data of other scanning cards in this LED box are transferred to subscan card 27, subscan card 27 by high-speed interface according to configuration
The image data that it shows with the image for carrying region, and carries non-self band in region is completed according to configuration information to continue toward this
Other scanning cards of LED box transmit.
From the foregoing description and Fig. 2 is it is known that in the LED display screen system of the present embodiment, and single led babinet includes one
A Hub plates 23 connect Hub plates 23 and cascade multiple LED lamp panels 26 and 28 with by winding displacement, wherein Hub plates 23 are configured with more
A scanning card interface two scanning card interface for example shown in Fig. 2, one of scanning card interface are used to connect main scanning card 25,
Another scanning card interface (is corresponded between two scanning card interfaces by PCB trace connection for connecting subscan card 27
It is that signal transmission is carried out by PCB trace between main scanning card 25 and subscan card 27).Certainly, the present invention is not limited to Fig. 2 institutes
The two scanning card interfaces shown can also be more scanning card interfaces, be carried out by PCB trace between each scanning card interface
Cascade.
Further it will be understood that in other embodiments, such as two scannings of multiple scanning card interfaces on Hub plates
Card interface can be used both independently of each in architecture system, such as the different network interfaces of sending card 21 are connected to by cable, such as
This two scanning card interfaces are used to configuration on connection main scanning card namely the same Hub plates, and there are two main scanning cards, same
The purpose for promoting screen body performance parameter can be reached.Certainly, being used to can between two of main scanning card scanning card interfaces of connection
To be not provided with PCB trace connection；PCB trace connection can also be still set, only if detecting that the when of being connected with cable is not
Image data is obtained by PCB trace, but image data is obtained by cable.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as be without departing from technical solution of the present invention content, it is right according to the technical essence of the invention
