Large Screen Display Wall System And Application

Along with the high speed increase of the social information, the requirement of information visibility is expanding sharply, simultaneously, the top level visibility is becoming more and more difficult Single-display-screen devices are far beyond the requirement of the market, especially for some Monitoring Centers, Directing Centers and scheduling Centers, the Patched Wide-Screen Display System that projecting from back has become the indispensable kernel basis of information visibility system.This dissertation is based on these phenomena The author firstly introduces the function and capability of the Wide-Screen Display System, and the development of this system is also described from domestic to abroad And then the author analyses the hardware component of this system, resulting the selection of DLP projector and data Gathering, Displaying card form DATAPATH as the hardware basis of the target system Finally the author makes the analysis and design in depth on the software of the Wide-Screen Display System which based on a serious of special hardware.This software suit is composed of Image Patch Process Software and Patch Controller The core is driving the processor and other hardware to cooperate through the Controller, to complete the image patch display work.The author researches three "seamlessness" in depth, that is, the seamless switch of the signal source of a single window, seamless switch of the entire screen and the seamless patching of the projecting areas Expatiate on the process of how the flow running, witch makes a characteristic of this system It engineers a serious of methods to deal with emergency, which add up to the usability and stability of the system.
