Embodiment
Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
referring to Fig. 1, the utility model is a kind of super large resolution LED splice displaying system, by master control set, several Gather and input devices, data bus, several splicing display devices, several LED send card and form, described master control set 102 by data bus respectively with several Gather and input devices, several splicing display devices connect, several splicing display devices and several LED send to link and connect, wherein, described splicing display device is responsible for being spliced to form one and is shown output and uniformly output be assigned to the DVI delivery outlet of some each and every one standards, then export to LED and send card, sending card by LED again converts displaying contents to dot matrix signal and is transferred to corresponding LED display and shows.The image data stream that the Gather and input device transmits is processed in the demonstration output of whole super large resolution and is shown by various images.And the control of whole system is to say the word to unify co-ordination by controlling software to master control set 102.Described splicing display device comprises display screen body, dead bolt button, register pin, web joint, bolt plate, anticreep spring card, C type web member, described register pin, dead bolt button are fixed on the back side of display screen body, bolt plate, anticreep spring card, C type web member are fixed on web joint, dead bolt button and register pin insert web joint, bolt plate is inserted the dead bolt button, be used for the display screen body is constantly tightened up to the web joint center at connection procedure, the anticreep spring card blocks bolt plate, is used for preventing that the display screen body from retreating and getting loose.
Principle of the present utility model is: utilize the Gather and input device that the signals collecting of various forms and the packet that converts specific format to are transferred to splicing display device Out1 by Ultrahigh speed data bus 103, and Out2 ..., Outx.Splicing display device Out1, Out2 ..., Outx is responsible for being spliced to form the demonstration output of a super large resolution and uniformly output being assigned to the DVI delivery outlet of several standards.Each DVI delivery outlet flows to corresponding LED and sends card.Take the layout of 2 row 4 row as example, if the resolution of single delivery outlet is 1920x1200, it is 1920*4=7680 pixel that so total resolution just can be supported wide, a high 1200*2=2400 pixel.Splicing display device Out1, Out2 ..., Outx also be responsible for to receive the image data stream that the Gather and input device transmits and processes in the demonstration of whole super large resolution and export and show by image scaling.And the control of whole system is to say the word to unify co-ordination by controlling software to master control set 102.
The LED that sells on the market sends card L1, L2 ..., the pixel that Lx can be shown by technical limitation is all conditional, generally can not surpass 2048x640, just seems unable to do what one wishes when the image that will show larger resolution (such as 7680x2400).Thereby and can being assigned to a plurality of delivery outlets to the resolution of super large uniformly by splicing display device dexterously, the utility model solved this difficult problem.Can be spliced into a unified demonstration desktop, carry out resolution uniform distribution and configure generic display chip in logic in the mode of tiled display drive software and splice and show.
The utility model Gather and input device In1, In2 ..., Inx and splicing display device Out1, Out2 ..., the quantity of Outx can flexible configuration.Master control set 102 is sent out the control command detection and is plugged on Ultrahigh speed data bus 103 specifically the device of what type and quantity powering up after starting the form that can adopt broadcasting.So just can realize rapid configuration and use.
The utility model adopts visual control software to control, and user interface is simple and easy to use.Control between software and master control set a standardized control protocol of cover is arranged, control software and can send order by the requirement of control protocol to master control set by network or serial ports, receive orders resolve command afterwards and translate into order that hardware can identify and construct control command by drive software Gather and input device and splicing display device are controlled of master control set.What as shown in Figure 1, dotted arrow represented is exactly control command.
Master control set 102 described in the utility model is a kind of general in CPU, main memory, external storage and corresponding I/O port and and the responsible control of control port and coordinate the device of whole device work.
Various Gather and input device In1 described in the utility model, In2 ..., Inx is by various acquisition chips, pcb board, buffer memory RAM, interface chip, the device that analog-digital chip etc. form.Main being responsible for is transferred to splicing display device Out1 to the signals collecting of various forms and the packet that converts specific format to by Ultrahigh speed data bus 103, Out2 ..., Outx.
Bus described in the utility model is to transmit the common communication main line of information between the various functional parts of computing machine.Can be divided into pci bus by type, PCI-X bus, AGP bus, PCI-E bus.Wherein up-to-date PCI-E bus adopts point-to-point connected in series, the shared parallel architecture of relatively early stage computer bus, each equipment has the special use of oneself to connect, do not need to whole bus request bandwidth, and can bring up to a very high frequency to data transmission rate, can reach the bandwidth of superelevation.Can only realize one-way transmission with respect to traditional PCI bus within the single time cycle, PCI-E can be operated in full-duplex mode.Up-to-date PCI-E3.0 standard rises to 8GHz|8GT/s with data transmission rate, and based on this, the unidirectional bandwidth of PCI-E3.0 framework single channel (x1) can be near 1GB/s, and the two-way bandwidth of 16 channels (x16) can reach 32GB/s especially.PCI-E3.0 has also increased 128b/130b decoding mechanism simultaneously especially, can guarantee almost 100% transfer efficiency.
The splicing display device Out1 that the utility model is mentioned, Out2 ..., Outx is by picture processing chip GPU, pcb board, buffer memory RAM, the device that interface chip etc. form.Be responsible for being spliced to form the demonstration output of a super large resolution and uniformly output being assigned to the DVI delivery outlet of some each and every one standards.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
