Abstract
The invention relates to a jointed screen system, in particular to a method and a device for jointing display screens. The method forms a serial bus of video data and makes the display screens connected with the bus in series. The data bandwidth of the serial bus does not increase with the increase in the number of the display screens, so the system may comprise an almost infinite number of screens. Thus, a problem of the prior is solved successfully. The method and the device have the advantages of allowing an infinite number of screens to be added in the system without increasing the load of the system nor reducing the quality of video frequency, and making the time differences between the arrivals of video data at the screens extremely small at the same time. When the method is used, the problem of limited number of screens of the jointed screen system is solved, so that the jointed screen system has a larger display area and more display contents.
Description
Technical field
The present invention relates to the mosaic screen system, relate in particular to a kind of method and device thereof that is used for jointing display screens.
Background technology
At present, the liquid crystal-spliced screen that is used to enlarge the area of display image or increases content displayed, with the high definition that it was possessed, wide visible angle, high brightness, advantage such as long-life and be user's favor gradually, at control and command, fields such as video conferencing and advertisement displaying are extensive use of, but at present the mosaic screen system adopts is that data are duplicated and the mode of distributing is come the establishment system, make in this way and can be subjected to the data distributor signal quality, the influence of factors such as bandwidth and the quantity of mosaic screen can't being increased to a lot, further lifting performance to the mosaic screen system has caused obstacle, as shown in Figure 1.Up to now, yet there are no the open report that in the mosaic screen system, has good solution to further expand display screen quantity.
Summary of the invention
The present invention is for overcoming the deficiencies in the prior art part, purpose is to provide a kind of method that is used for jointing display screens, this method forms universal serial bus with video data, and display screen is serially connected on this bus, owing to the data bandwidth on the universal serial bus can not increase because of the increase of display screen quantity, therefore the increasable number of screen of this system is almost unrestricted, has successfully solved problems of the prior art.
Another object of the present invention is to provide a kind of device that is used for jointing display screens, this device aims at and is used to realize the preceding method hardware device.
The present invention achieves the above object by the following technical programs: a kind of method that is used for jointing display screens comprises the steps: 1) serial data bus of design, the video source transmitter is connected on this bus; 2) each digital indicator with whole digital display screen is connected on this bus by its corresponding display node strings;
3) pass through the stitching image positional parameter that each display node is set the corresponding required demonstration of digital indicator;
4) the video source transmitter sends to video data on this bus;
5) the display node obtains video data and is used for tiled display according to the digital indicator video data that the parameter that step 3) is set sends to this display node correspondence;
6) the display node carries out the quality recovery to the video data on the bus, and sends downwards;
7) next display node receives video data and repeats the operation of step 4), step 5), step 6).
As preferably, this bus can be designed to open loop or closed loop.
As preferably, when bus design was closed loop, the video source transmitter can be arranged on the bus optional position.
Adopt a kind of device that is used for jointing display screens as above-mentioned method, comprise video source transmitter, serial data bus, any a plurality of display nodes, any a plurality of digital indicators, wherein: the video source transmitter links to each other with serial data bus, each display node is arranged on the serial data bus, and the digital display screen that each display node is corresponding with it links to each other.
As preferably, described display node is the Video processing integrated circuit board.
As preferably, the display node also can be set directly in the display screen.
As preferably, any a plurality of display nodes are 16 display nodes, and any a plurality of digital indicators are 16 digital indicators.
Beneficial effect of the present invention: the present invention can be increased to number of screen in the system unlimited many, and can not increase the load of system, reduces the quality of vision signal, and the time difference that the while video data arrives each screen is also very little.The use of this method can the mosaic screen system in the limited problem of number of screen, make the mosaic screen system have bigger display area and more displaying contents.
Description of drawings
Fig. 1 is the synoptic diagram of mosaic screen system data transmission in the prior art;
Fig. 2 is to use the structural representation of the device that is used for jointing display screens of serial video data bus.
Embodiment
Embodiment 1: the present invention is described further below in conjunction with specific embodiment, but protection scope of the present invention is not limited in this:
A kind of device that is used for jointing display screens, as shown in Figure 2, form by video source transmitter 2, serial data bus, 16 display nodes, 16 digital indicators 1, wherein: the video source transmitter links to each other with serial data bus, each display node is arranged on the serial data bus, and the digital display screen that each display node is corresponding with it links to each other; Described serial node is a Video processing integrated circuit board 3, each digital display screen of mosaic screen is linked to each other with this integrated circuit board 3, configuration integrated circuit board 3 needs content displayed to digital display screen, thereby make whole mosaic screen can demonstrate the image of requirement, according to the needs of system, can increase the quantity of screen arbitrarily by adding a plurality of these processing integrated circuit boards 3.Video processing integrated circuit board 3 also can be set directly in the digital display screen 2.
The main effect of this integrated circuit board is to receive the data that the upper level integrated circuit board sends, and can be wherein partly or entirely data be sent to the digital display screen demonstration, simultaneously total data is sent to the next stage integrated circuit board, form a serial data bus like this.
Concrete workflow:
1) serial data bus of design, this bus design is open loop, and the video source transmitter is connected on this bus;
2) each digital indicator with whole digital display screen is connected on this bus by its corresponding display node strings;
3) pass through the stitching image positional parameter that each display node is set the corresponding required demonstration of digital indicator;
4) the video source transmitter sends to video data on this bus;
5) the display node obtains video data and is used for tiled display according to the digital indicator video data that the parameter that step 3) is set sends to this display node correspondence;
