The invention relates to a tiled circuit module for an LCD large screen and a control method thereof. The circuit comprises at least one signal input and S blocks; the S blocks can be divided into N horizontal blocks and M vertical blocks; every block comprises a master SCALER module with zoom function; signals are input to the master SCALER module of the first block, then transmitted to the second horizontal block, the last horizontal block and the second vertical block and then connected to the last block in sequence. The circuit module has the advantages of: making full use of the time sequence division technique of the LCD main control panel SCALER to realize the division of images and form a large screen, adding no cost on the basis of a display with a lowest cost in tiled displayed walls, flexible operation, and being capable of first installation and then combination.
Description
Technical field
The present invention relates to a kind of LCD giant-screen, relate in particular to this LCD large-screen splicing circuit module and control method thereof.
Background technology
In the LCD large-screen splicing, splicing system mainly is made up of three parts, large tiled display wall, projector array, control system.Wherein control system is a core.
Popular in the world splicing control system mainly contains three types, the splicing system that hardware splicing system, software splicing system, software combine with hardware at present.
The hardware splicing system is: showing an independently picture with any screen, is that Real time dynamic display is installed owing to adopt the hardware stitching image to handle fully, simple to operate; But shortcoming is the splicing small scale, the needs of incompatibility multi-screen splicing, and institute's windowing is fixed as a screen size.
The software splicing system is: the multi-screen display card is a kind of special display card, has another name called the large screen splicing card; It can realize that a plurality of screens show a big picture multihead display card, can make a PC support many display/TVs; On different screens, show different separately pictures, but several display/televisors big picture of the mutual group unification width of cloth again; Can on a computing machine polylith card be installed simultaneously in addition, number of screen is selected arbitrarily, and ScreenMode is arranged arbitrarily; But this mode must have PC support; And the broadcast program source is restricted; That realizes image cuts apart that at first cost is expensive, complicated operation, and wiring is many.The all direct line display wall controller of each display and PC is except having the CPU of test pattern workstation, storer, outside IO interface and the operating system, also has multi-channel video, the RGB IO interface, can be with multiple external video, behind the RGB analog signal digital, in the imaging device imaging, convert the single channel simulating signal again to and output to giant-screen, and can on giant-screen, arbitrarily move, amplify and dwindle, the seamless spliced of screen multiwindow arbitrary dimension striden in realization, as operating flexible at a big window, convenient, this process is also referred to as soft splicing, and the display wall controller also is soft assembly controller.This specialized equipment that belongs to costs an arm and a leg.
The splicing system that software combines with hardware is the advantage of above two kinds of methods comprehensively, overcomes its shortcoming.
As seen from Figure 1: the circuit module of each piece is made up of dedicated graphics processors; Outside vision signal at first is input to visual control system, matrix through visual control system switches, the vision signal that output needs, the special image processor that enters into each display again cuts demonstration (software is finished writing in advance, and the display opsition dependent is put) to image.
Dedicated graphics processors has two problems: the firstth, belong to specialized equipment, and maintenance and cost are more expensive; The secondth, must realize with visual control system if in the middle of large-size screen monitors, open wicket again, cause costing an arm and a leg, be unfavorable for applying of large-size screen monitors
Summary of the invention
The technical issues that need to address of the present invention have provided spliced circuit module in a kind of LCD giant-screen, are intended to solve the above problems;
The present invention also provides the joining method of foregoing circuit module;
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
Spliced circuit module of the present invention comprises: at least more than one signal input, S piece; A described S piece can be divided into N horizontal direction piece and M vertical direction piece; Described each piece comprises a master control SCALER module (liquid crystal display drive plate) that zoom function is arranged; Signal is input to the master control SCALER module in first; Master control SCALER module in described first is passed to second horizontal piece, last horizontal piece is input to second vertical piece again; Be connected to last piece successively.
Method of the present invention realizes by following steps:
Input signal enters the SCALER of master control borad, selects the signal of input by telepilot;
The image of input extracted by sampling according to the requirement of setting be put into image buffer;
Again by comprising that image quality processing, format conversion, scaled, sequential conversion sequential processing drive screen;
Compared with prior art, the invention has the beneficial effects as follows: the sequential isolation technique that makes full use of LCD master control borad SCALER, realize cutting apart of image, and be combined into a giant-screen, advantage is not increase cost on the basis of display, is that cost is minimum in the assembly wall, and flexible operation, the back combination can be installed earlier.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 2: spliced circuit module of the present invention comprises: at least more than one signal input, S piece; A described S piece can be divided into N horizontal direction piece and M vertical direction piece; Described each piece includes a master control SCALER module (liquid crystal display drive plate) of zoom function; Signal is input to the master control SCALER module in first; Master control SCALER module in described first is passed to second horizontal piece, last horizontal piece is input to second vertical piece again; Be connected to last piece successively;
As seen from Figure 3: the signal of importing in master control SCALER module at first passes through the sampling of liquid crystal display drive plate, and the image 1/MXN that needs are shown extracts on request, is put into SDRAM, through the processing of SCALER;
Described at least more than one signal input can be one or more among VGA, HDMI, the YpbPr.
As seen from Figure 4: method of the present invention realizes by following steps:
Input signal enters the SCALER of master control borad, selects the signal of input by telepilot;
The image of input extracted by sampling according to the requirement of setting be put into image buffer;
Again by comprising that sequential processings such as image quality processing, format conversion, scaled, sequential conversion drive screen;
The described signal of selecting to import by telepilot is: VGA YPbPr HDMI;
In menu, set the number of piecing together screen;
X/Y sets the number that will piece together screen, is up to 10 * 10;
Import the position that current screen will show in entire image.
The image of input is handled (mainly comprising image quality processing, format conversion, scaled, sequential conversion etc.) then through over-sampling in image processor.After inner a series of processing, digital video signal is transformed to and meets LCD flat panel data presented form and sequential, drives liquid crystal display and shows.
