Embodiment
Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Referring to Fig. 1; The utility model is a kind of super large resolution LED splicing display device; By main control module; Several that can support DVI, VGA, video format signal are respectively gathered load modules, data bus, several splicing display modules, several LED and are sent card and form, said main control module 102 through data bus gather load modules with several respectively, several splicing display modules are connected, several splicing display modules and several LED transmission card connection; Wherein, Said splicing display module is responsible for being spliced to form a DVI delivery outlet that shows output and be assigned to output rxc standard uniformly, exports to LED then and sends card, sends card by LED again and converts displaying contents to LED display that dot matrix signal is transferred to correspondence and show.The image data stream that the collection load module transmits shows in the demonstration output of whole super large resolution through various Flame Image Process.And the control of total system is to say the word united and coordinating work for main control module 102 through Control Software.
The principle of the utility model is: utilize to gather load module and is transferred to the signals collecting of various forms and the packet that converts specific format to through hypervelocity data bus 103 and splices display module Out1, and Out2 ..., Outx.Splicing display module Out1, Out2 ..., the DVI delivery outlet that Outx then is responsible for being spliced to form the demonstration output of a super large resolution and is assigned to output rxc standard uniformly.Each DVI delivery outlet flows to corresponding LED and sends card.Layout with one 2 row 4 row is an example, if the resolution of single delivery outlet is 1920x1200, so total resolution just can be supported the wide 1920*4=7680 of a being pixel, a high 1200*2=2400 pixel.Splicing display module Out1, Out2 ..., the image data stream that the also responsible reception collection of Outx load module transmits is handled in the demonstration output of whole super large resolution through image zoom and is shown.And the control of total system is to say the word united and coordinating work for main control module 102 through Control Software.
The LED that sells on the market sends card L1, L2 ..., the pixel that Lx can be shown by technical limitation all is conditional, generally can not surpass 2048x640, just seems unable to do what one wishes when the image that will show bigger resolution (such as 7680x2400).And thereby the utility model can be assigned to a plurality of delivery outlets to the resolution of super large uniformly and solved this difficult problem through the splicing display module dexterously.Can be spliced into a unified demonstration desktop, carry out resolution uniform distribution and configure generic display chip in logic with the mode of splicing display driver software and splice and show.
The utility model is gathered load module In1, In2 ..., Inx and splicing display module Out1, Out2 ..., the quantity of Outx can flexible configuration.To send out that the control command detection is plugged on the hypervelocity data bus 103 specifically be the module and the quantity of what type to main control module 102 powering up the form that can adopt broadcasting after starting.So just can realize configuration fast and use.
The utility model adopts visual Control Software to control, and user interface is simple and easy to use.The standardized control protocol of one cover is arranged between Control Software and the main control module; Control Software can be sent order by the requirement of control protocol to main control module through network or serial ports, after main control module receives orders resolve command and translate into order that hardware can discern through drive software structure control command to the collection load module with splice display module and control.As shown in Figure 1, what dotted arrow was represented is exactly control command.
The described main control module 102 of the utility model is a kind of general CPU that have, main memory, external storage and corresponding I/O port and with the responsible control of control port with coordinate the module of whole device work.
The described various collection load module In1 of the utility model, In2 ..., Inx is by various acquisition chips, pcb board, buffer memory RAM, interface chip, the module that analog-digital chip etc. constitute.Main be responsible for being transferred to the signals collecting of various forms and the packet that converts specific format to through hypervelocity data bus 103 splice display module Out1, Out2 ..., Outx.
The described bus of 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 early stage relatively computer bus; Each equipment all has the special use of oneself to connect; Need be to whole bus request bandwidth, and can bring up to a very high frequency to data transmission rate, can reach the bandwidth of superelevation.In the single time cycle, can only realize one-way transmission with respect to traditional PCI bus, PCI-E can be operated in full-duplex mode.Up-to-date PCI-E 3.0 standards rise to 8GHz|8GT/s with data transmission rate, and based on this, the unidirectional bandwidth of PCI-E 3.0 framework single channels (x1) can be near 1GB/s, and the two-way bandwidth of 16 channels (x16) can reach 32GB/s especially.PCI-E 3.0 has also increased 128b/130b decoding mechanism simultaneously especially, can guarantee almost 100% transfer efficiency.
The splicing display module Out1 that the utility model is mentioned, Out2 ..., Outx is by picture processing chip GPU, pcb board, buffer memory RAM, the module that interface chip etc. constitute.The DVI delivery outlet of being responsible for being spliced to form the demonstration output of a super large resolution and being assigned to output rxc standard uniformly.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to the utility model is extended out or change still are in the row of the protection domain of the utility model.
