The utility model is connected with a universal computer output interface and is also connected with the LED electronic display. The utility model is characterized in that the synchronous controller is arranged inside a box and is provided with a USB interface line which is used for being connected with the USB interface of the universal computer. As the controller controls the LED electronic display through the USB interface, the controller with the USB interface is connected with a universal computer and the USB interface is common in the prior universal computer, the utility model is convenient to be connected with various universal computers and easily realizes the large screen output with low cost.
Description
Technical field
The utility model relates to the isochronous controller of a kind of light emitting diode (LED) electronic display, in particular a kind of improvement of LED electronic display isochronous controller interface.
Background technology
The LED electronic display of prior art is widely used at advertising sector and some public places, especially large-scale advertisement LED electronic display, and the broadcast of its video and demonstration need the interface transmission of special setting.
At present common LED electronic display connects a multi-purpose computer usually, and carries out the broadcast output demonstration of video by the DVI delivery outlet on the video card of this multi-purpose computer, and there are many deficiencies in this mode, mainly comprises:
Because used usually at present DVI output interface operated by rotary motion is on video card, dependence to video card is very strong, common computer comprises that notebook computer can not be used for controlling the LED electronic display usually, must use the work that is equipped with special-purpose video card could guarantee the LED electronic display, and the cost of these special-purpose video cards is higher.And use these video display systems must adopt desktop computer, and be inconvenient to carry, be not easy to operation and maintenance at the construction field (site).
In addition, the area of present LED electronic display is increasing, when the area size of LED electronic display surpasses the ultimate resolution of a display, must be by means of front end video source independently, video is carried out seamless spliced processing, be inconvenient to install and the volume of front end video source is heavy, and cost an arm and a leg, can't promote on a large scale.
Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide the isochronous controller that adopts USB interface control light emitting diode electronic display, by adopting the isochronous controller of USB interface, realize that any common computer comprises that notebook can export to vision signal the LED electronic display, and realize simple the seamless spliced output of large tracts of land video.
The technical solution of the utility model is as follows:
Adopt the isochronous controller of USB interface control light emitting diode electronic display, it connects the output interface of a multi-purpose computer, and is connected to a LED electronic display; Wherein, described isochronous controller is arranged in the box body, and is provided with a usb line, is used for being connected with the USB interface of described multi-purpose computer, gathers the vision signal of this multi-purpose computer.
Described isochronous controller, wherein, described isochronous controller also connects the receiving card of a control system by optical fiber or CAT5E UTP cable, connects winding displacement by this receiving card and at least one data and is connected on the described LED electronic display.
Described isochronous controller wherein, also connects a plurality of isochronous controllers on the described multi-purpose computer, be used to carry out the seamless spliced processing of picture.
The isochronous controller of employing USB interface control light emitting diode electronic display provided by the utility model, owing to adopted the isochronous controller of USB interface to connect multi-purpose computer, be used for the vision signal of collecting computer, and USB interface setting on existing multi-purpose computer is comparatively general, made things convenient for and being connected of any style multi-purpose computer, and it realizes that when giant-screen is exported simply cost is low.
Description of drawings
Fig. 1 is a circuit function block diagram of the present utility model;
Fig. 2 is a USB interface structural representation of the present utility model.
Embodiment
Below preferred embodiment of the present utility model is described in detail.
The isochronous controller 100 of employing USB interface control light emitting diode electronic display of the present utility model, as depicted in figs. 1 and 2, be arranged in the box body 110, and be connected on the USB interface of a multi-purpose computer 200 by a usb line 120, because the USB interface of multi-purpose computer is comparatively common at present, interface standard is USB2.0 usually at present.
LED electronic display of the present utility model is by above-mentioned isochronous controller, can gather the required video signal displayed of display screen from described multi-purpose computer, need to be provided with a driver on this multi-purpose computer, this driver is that prior art is known, therefore, repeat no more.With described isochronous controller by usb line with after multi-purpose computer is connected, driver to isochronous controller can be installed, gather vision signal by USB interface from this multi-purpose computer then, and by subsequent treatment formation network data, connect and send on the system's receiving card 130 after the described LED electronic display, as shown in Figure 1 by common five class netting twines or the optical fiber of surpassing.This receiving card 130 is handled received network video signal, make it to become described LED electronic display cell board and show needed signal, connect each cell board that winding displacement is connected to the LED electronic display by data then, can realize the output and the demonstration of video.
Same multi-purpose computer of the present utility model can have a plurality of USB interface, perhaps also can adopt the USB divider to expand a plurality of USB interface, therefore, can on same multi-purpose computer, connect a plurality of isochronous controllers of the present utility model at an easy rate, software processes by multi-purpose computer realizes many cover systems are carried out seamless spliced output, like this, the isochronous controller of USB interface of the present utility model just can expand easily, be particularly suited for large LED electronic display, to realize of the seamless spliced outputs of many cover isochronous controllers more than the much lower cost of prior art to the big screen LED electronic display in stadiums or the setting of buildings eminence.
The mode of the isochronous controller acquired signal of the utility model employing USB interface control light emitting diode electronic display is owing to adopted the mode of USB interface, especially present USB2.0 interface, broken away from dependence, can comprise the control system of notebook computer realization with common computer as the LED electronic display to video card DVI interface; And the expansion of USB interface is very easy, can realize carrying out seamless spliced demonstration and output from the screen signal of a plurality of USB interface outputs by the software on the multi-purpose computer.
The particularly important is, isochronous controller of the present utility model separates independent the setting with multi-purpose computer, and its connecting line is by usb line, The whole control system can be made external set top box, thereby convenient to carrying of site operation personnel.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
