This topic firstly introduces the LED display of development and application situation. In the first chapter describes the LED display device of basic working principles and characteristics, introduces in detail the destem concrete circuit and parameters. The second chapter for wide application in the graphic display, introduced the basic component of it after part of the LED display circuit of the in-depth analysis, and presents the hardware circuit diagram and complete practical programming list all the assembly language. The third chapter of content is image display, focuses on analyzing the led screen gray control method, and introduces the integrated circuit TLC5902 the characteristic and application. The fourth chapter discusses the most advanced video screen at video signal, the organization, video LED display structure, main IC chip, and related application software etc, are introduced DS90C031 etc ZQL9701, the technology of microarray characteristics and LEDSHOW, & ldquo; LED management tools & rdquo software use method. Book was a I LED the industry standard. Book available to undertake various kinds of the led sign work of engineering and technical personnel, also can be used as reference to the relevant professional colleges and universities teaching reference or materials.

The LED display is using light-emitting diodes dot matrix modules or pixel unit composed of a flat display screen. Because of its high lighting rate is high, long service life, configure, flexible, rich color and for indoor and outdoor environment adaptiveness wait for an advantage, since the late 1980s LED manufacturing technology that starts with the continuous improvement in foreign been widely used. In our country, especially after the reform and opening to the national economy in the 1990s growth, for public release information demand increasingly intense, led screen appear precisely adapted to the market situation, thus in the LED display design and manufacturing technology and application level are obtained a rapid increase. The LED display experienced from monochrome, double-color graphic display, to image display, until today video display the full color the development process. Whether during performance (enhance brightness led sign and blue glow lights etc) and system composition (computerized all aspects of dynamic display system) has made much progress. At present already reached video display brightness full color, can say the level to meet requirements of various application conditions. Its application field has pervaded traffic, telecom, advertising, promotional and other aspects. Our country LED display development can say basically and world level synchronization, has already formed a fairly development potential of the industry. It should be noted that our country LED industry not only in application technology has been a huge success, and in the innovation ability well, such as Beijing ZhongQing data equipment company developed ZQL9701 vlsi chip, represents the current .
