外文资料原文 Large screen display system's research Led development Along with computer technology's high speed development, LED (Light Emitting Diode) the screen display system takes after the television, the broadcast, the newspaper, the magazine “the fifth big media” marches into the social life fast each aspect. Its collection microelectronic technology, the computer technology, the information processing and management technology in a body, may the information through the writing, the design, the animation and the video frequency four forms demonstrates. With media and so on bank of television monitors, magnetism vane compares, the LED large screen display system has the design to be artistic, the color is sharp; The design, the color change are rich, are fast; The low power loss, the long life, the use cost low, work stably reliable and so on characteristics. It demonstrated the chart article angle of view is big, the apparent distance is far, thus has widely applied in the large-scale square, the commercial advertizing, the sports complexes, the information dissemination, the news issue, the securities trading; It also applies in the industrial control and the industry reassignment system, is advantageous each kind of parameter, the alarm point, the technical process demonstrates clearly perfect, may satisfy the different environment the need. The LED display monitor is one kind of use computer and the complex digital signal processing electron advertisements propaganda screen. Its screen body part by the microprocessor (is mainly monolithic integrated circuit) and the driving circuit control movement, demonstrated the image or the writing obtain by the computer edition software editor. Because the LE...
