Utility model content
For the deficiency in structure in the prior art, the utility model provides one kind, and there is multiway images signal to access simultaneously
Ability and with the multi-picture splicing display of a variety of image display modes such as single-image, picture-in-picture, four pictures.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：The utility model provides a kind of multi-picture splicing
Display, including mainboard and it is respectively connecting to the video input module of the mainboard, power transfer module, key-press module, control
Molding block and driver module；
The driver module is connected with LCDs, and it is defeated that the video input module includes 6 pieces of DVI/VGA videos
Enter plate and 1 block of AV/HDMI video input plate；
The power transfer module is connected with the mainboard and institute's LCDs and provides electric power respectively, the power supply
Modular converter is connected to the external power supply.
The beneficial effects of the utility model are：Multiway images signal can be realized while access and there is single-image, in picture
A variety of images such as picture, four pictures show that resolution ratio is big, and disposal ability is strong.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement.
Further, the electric power that the external power supply provides is converted into needed for multi-picture splicing display apparatus internal circuit
The various operating voltages wanted, ensure the steady operation of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：100th, mainboard；110th, power transfer module；
120th, key-press module；130th, driver module；140th, external power supply；150th, LCDs；160th, video input module；
170th, control module.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in figure 1, including mainboard 100 and it is respectively connecting to video input module 160, the power supply of the mainboard 100
Modular converter 110, key-press module 120, control module 170 and driver module 130；
The driver module 130 is connected with LCDs 150, and the video input module 160 includes 6 pieces of DVI/
VGA video inputs plate and 1 block of AV/HDMI video input plate；

Number carry out, mainboard is designed from the fpga chip EP2C8T144I8N of ALTERA companies, is passed through and is configured
The soft nucleus CPU of EP2C8T144I8N chips realizes multi-channel serial port, there is provided the conversion of the control configuration information of device interior；
Video input module is the important component of display, mainly realizes access and the splicing of vision signal, video
Input module includes 6 blocks of DVI/VGA video inputs plates and 1 block of AV/HDMI video input plate, and video input module can be according to need
The vision signal input for being configured to need is asked, and splicing can be carried out to the image of input as needed.Video input module
The design of board is carried out using the STDP9320 of ST companies as master chip；
Control module is the control configuration center of equipment, it receive come self-configuring interface RS232 interface/network interface or by
The user configuration order of keypad, the mode of operation or parameter of the other each modules of control device, realizes functions of the equipments；
Key-press module is user's operative configuration window that equipment provides, and user can realize equipment input letter by key-press module
Number selection and display pattern configuration；
Power transfer module, the unit of power output, it is direct current 12V by external alternating current 220V or direct current 24V power conversions
With 5V voltages, by mainboard by being worked to the other modules of equipment, function of supplying power is realized.
Driver module is the signal switching station of equipment, realizes and the image for completing processing and splicing is converted to and can connect
The LVDS signals for entering LCDs are shown；
LCDs is the critical piece of equipment, realizes the display to handling picture signal.LCDs selects platform
