Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is the structural representation of existing a kind of LED display screen system.
Fig. 2 is the structural representation of a kind of LED display screen system that the embodiment of the present invention proposes.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
The following embodiment of the present invention proposes a kind of new LED display screen system structure, in identical LED box specification, use this system architecture, scanning card number can be increased flexibly in a LED box, reach the object that each LED lamp panel can carry out cascade flexibly, thus obtain different screen body performance parameters to adapt to different occasions.
Particularly, see Fig. 2, the LED display screen system that the embodiment of the present invention proposes comprises: sending card 21, Hub plate 23, main sweep card 25, LED lamp panel 26, subscan card 27 and LED lamp panel 28; Each LED lamp panel 26 and 28 of corresponding same Hub plate 23 is spliced into LED box by connection Hub plate 23 and this LED box is configured with main sweep card 25 and subscan card 27.Wherein, sending card 21 is connected with head end video source (not drawing in figure) typically via its video interface such as DVI interface or HDMI etc., the vision signal of video source is converted to gigabit network interface or other transmit the signal format that interface faster supports, the rear end of sending card 21 is such as connected with main sweep card 25 via netting twine by gigabit network interface; Be connected typically via netting twine between main sweep card 25 with main sweep card 25.Main sweep card 25 has high-speed transmission interface to export, main sweep card 25 is connected by high-speed transmission interface with subscan card 27, and high-speed transmission interface herein can be parallel interface, also can be serial line interface, and realize (also namely forming electrical connection by PCB cabling between main sweep card 25 and subscan card 27) with PCB (printedcircuitboard, printed circuit board (PCB)) cabling form.Hub plate 23 has and supports that the interface of multiple scanning card such as arranges pin/row's maternal interface; Moreover, Hub plate 23 is such as provided with one for connecting the interface of main sweep card and one or more interface for auxiliary connection scanning card, and can is connect in cascaded fashion between each scanning card interface; Therefore, the scanning card by connecting varying number on Hub plate 23 can change screen body performance parameter.In addition, Hub plate 23 there is abundant lamp plate interface such as winding displacement interface to connect LED lamp panel; As shown in Figure 2, eight LED lamp panel 26 are unified into four strings by the lamp plate interface level of four on Hub plate 23 and are electrically connected main sweep card 25, eight LED lamp panel 28 and are unified into four strings by other four the lamp plate interface level on Hub plate 23 and are electrically connected subscan card 27.
Hold above-mentioned, LED box performance parameter require minimum in, Hub plate 23 is such as only connected with main sweep card 25 and not auxiliary connection scanning card 27, also namely the same with the system architecture scheme of Fig. 1.And when the requirement of LED box performance parameter is higher, by subscan card 27 is connected to the progression that Hub plate 23 (also namely adding subscan card 27 on Hub plate 23) reduces LED lamp panel cascade, thus screen body performance parameter can be improved.
More specifically, a subscan card 27 can be added on Hub plate 23, the performance parameter before reaching 2 times; Also can add three subscan cards 27 on Hub plate 23 and improve performance parameter further, reach the performance parameter of original 4 times, to adapt to the scene of high request.
Whether major and minor scanning cartoon is crossed has netting twine connection to carry out Intelligent Recognition, if scanning card has detected that netting twine connects, then this scanning card is main sweep card.Main sweep card 25 receives according to the view data of the parameter issued by whole LED box, and needs the view data of display to deliver to corresponding LED lamp panel 26 and show oneself; Moreover, the data of other scanning cards in this LED box are transferred to subscan card 27 by high-speed interface according to configuration by main sweep card 25, subscan card 27 completes according to configuration information the image display that its band carries region, and other scanning cards non-self band being carried to view data continuation this LED box past in region transmit.
State bright and Fig. 2 can learn in the past, in the LED display screen system of the present embodiment, single led casing comprises a Hub plate 23 is connected Hub plate 23 cascade multiple LED lamp panel 26 and 28 with by winding displacement, wherein, Hub plate 23 is configured with two the scanning card interfaces of multiple scanning card interface such as shown in Fig. 2, one of them scanning card interface is for connecting main sweep card 25, another scanning card interface is used for auxiliary connection scanning card 27, and connect (being carry out signal transmission by PCB cabling between corresponding main sweep card 25 and subscan card 27) by PCB cabling between two scanning card interfaces.Certainly, the present invention is not limited to the scanning card interface of two shown in Fig. 2, also can be more scanning card interface, carries out cascade between each scanning card interface by PCB cabling.
In addition, be understandable that, in other embodiments, multiple scanning card interfaces on Hub plate such as two scanning card interfaces can separately use when architecture system, the different network interfaces of sending card 21 are such as all connected to by netting twine, two scanning card interfaces like this are all for connecting main sweep card, and be also that same Hub plate is configured with two main sweep cards, it can reach the object promoting screen body performance parameter equally.Certainly, all between two of main sweep card scanning card interfaces, PCB cabling can not be set connect for connecting; Also still can arrange PCB cabling to connect, if be not obtain view data by PCB cabling when just detecting and be connected with netting twine, but obtain view data by netting twine.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
