The product of LCD TV splicing in the market, mainly still adopt DVI, even the signal such as VGA is realized the splicing of video wall, due to VGA or DVI, in signal transmission, decay can be larger, after being concatenated into the board of some, and the signal severity that still can decay, whole image quality can be affected, even due to signal excessively a little less than, cause normally display frame of system, be relatively difficult to realize the video wall splicing of large matrix.
Known technology disappearance:
One, the video wall that the analog signal such as VGA, DVI, Ypbpr forms, because analog signal attenuation ratio in transmitting procedure is more serious, video wall image quality can be affected, and is unfavorable for splicing large-size screen monitors video wall.
Two, signal serial connection requires harshness, and as supported VGA output serial connection, its input request signal is necessary for VGA signal, if same DVT or HDMI output serial connection, also the necessary corresponding DVI of signal or the HDMI that require input, higher to the equipment requirement of input signal, be unfavorable for that terminal use selects.
Three, for realizing multi-signal serial connection, must provide many groups serial connection loop and interface, as VGA in/out, DVI in/out, Ypbpr in/out etc., are unfavorable for cost.
Summary of the invention
It is a kind of simple in structure, with low cost that the purpose of this utility model is to provide, be easy to promote, and can realize large-scale LCD TV wall splicing based on DisplayPort, realize the control device of video wall splicing.
For achieving the above object, the technical solution of the utility model is: a kind of control device of realizing video wall splicing based on DisplayPort, comprises a signal source input module and N splicing control unit; Described N splicing control unit includes the DP signal conversion module, the image that connect successively and selects driver module and display module; Described signal source input module is connected to respectively the image of the first splicing control unit and selects driver module and DP signal conversion module, the image of m splicing control unit selects driver module to be also connected to the DP signal conversion module of m+1 splicing control unit, wherein, N, m are natural number, and N > 1,1≤m≤N-1.
In the utility model embodiment, described signal source input module is HDMI signal conversion module, and this HDMI signal conversion module adopts ADI ADV7630 IC chip, and its support converts the unification of four groups of DVI/HDMI input signals to HDMI signal.
In the utility model embodiment, described DP signal conversion module all adopts ST STDP4328 IC chip.
In the utility model embodiment, described image selects driver module to be Scalar IC processing module, and this Scalar IC processing module adopts ST STDP9320 chip.
In the utility model embodiment, described Scalar IC processing module also comprises Flash memory module and the DDR3 RAM being connected with described ST STDP9320 chip.
In the utility model embodiment, described display module all adopts LCD display.
Compared to prior art, the utlity model has following beneficial effect:
One, adopt DP signal to realize video wall splicing, support existing market main flow 1080P, 4K*2K liquid crystal panel shows demand, realizes video wall high definition image quality and shows;
Two, adopt DP signal serial connection, signal is decayed less in transmitting procedure, can realize large-size screen monitors video wall splicing;
Three, adopt digital signal conversion hardware loop design, by the input of the TMDS digital signals such as DVI/HDMI/DP, the unified DP that is converted to exports, and only needs one group of DP in/out connect product, can realize multi-signal serial connection video wall, reduces manufacture and maintenance cost.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is specifically described.
As shown in Figure 1, a kind of control device of realizing video wall splicing based on DisplayPort of the present utility model, comprises a signal source input module and N splicing control unit; Described N splicing control unit includes the DP signal conversion module (DP is DisplayPort), the image that connect successively and selects driver module and display module; Described signal source input module is connected to respectively the image of the first splicing control unit and selects driver module and DP signal conversion module, the image of m splicing control unit selects driver module to be also connected to the DP signal conversion module of m+1 splicing control unit, wherein, N, m are natural number, and N > 1,1≤m≤N-1.
Described signal source input module is HDMI signal conversion module, and this HDMI signal conversion module adopts ADI ADV7630 IC chip, and its support converts the unification of four groups of DVI/HDMI input signals to HDMI signal; Described DP signal conversion module all adopts ST STDP4328 IC chip; Described image selects driver module to be Scalar IC processing module, and this Scalar IC processing module adopts ST STDP9320 chip; Described Scalar IC processing module also comprises Flash memory module and the DDR3 RAM being connected with described ST STDP9320 chip; Described display module all adopts LCD display.
It is below specific embodiment of the utility model.
Hardware designs of the present utility model probably has several functional modules, first be HDMI signal conversion loop, adopt ADI ADV7630 IC, its support converts the unification of four groups of DVI/HDMI input signals to HDMI signal, secondly by the HDMI signal via after ADV7630 IC conversion, through ST STDP4328 IC, the conversion of DP signal is changed behind loop, directly change into DP signal, finally deliver to Scalar IC(ST STDP9320) process chip, and gain after amplification to DP signal in Scalar IC inside, two-way output, one tunnel outputs to LCD display, the DP out interface of separately leading up to is exported next board as input signal, thereby realize maximum and can reach 10 * 10 even larger matrix video wall splicings.
