First, the system overview
DLP large-screen display system is guided by the theory of system engineering, information engineering, automation control, DLP display technology and equipment, projection wall splicing technology, multi-screen image processing technology, multi-channel signal switching technology, network technology, centralized control technology, etc. In one, it can display signals from a variety of different sources, such as computers, cameras, DVD-Videos, and networks, to meet the needs of users to display a variety of shared information and comprehensive information.
Second, the system composition
The DLP large-screen display system is mainly composed of the following parts:
(1) DLP display wall unit
(2) Image processor
(3) Large screen management software
(4) Signal switching system (optional)
(5) Control computer
Third, the system schematic
Fourth, the system function is realized
1. Full-screen display, high-definition, high-resolution applications can use the large-screen display wall as a unified logic screen to display high-definition, high-resolution images, to achieve full-screen display and resolution overlay, such as large ultra-high resolution display Network screens, etc.
2. Multiple video signal display
Support all-standard Video input signals, Video surveillance information, high-definition video images, high-definition cameras, video recorders, video players, color physical display devices and other video sources can access the graphics processor. After the multi-channel Video signal passes through the graphics processor, it can be enlarged, reduced, multi-screened, and full-screen displayed at any position on the display wall in the form of a window.
3. Display of network signals
The image processor can freely open multiple remote IP windows, dynamically display the remote computer screen on the large screen through the network, and the remote IP window can roam, drag and drop, resize, and superimpose with other windows without restriction.
4. Various types of signal mixed display
The image processor has the functions of processing computer graphics signals with ultra-high resolution stitching, multi-screen display of high-definition video signals and RGB signals, and superimposed display of different types of signals, and any of the signal windows can be arbitrarily reduced, enlarged, multi-screen or full screen. display.
5. Multi-channel RGB and Video signal real-time display support multi-channel RGB signal and Video signal real-time display function.
