LED monochrome display is the use of light-emitting diode dot matrix module, or pixel unit composed of flat display screen. Because of its high luminous efficiency, long service life, flexible configuration, rich color and adaptability to indoor and outdoor environment, since the late 1980s, with the LED manufacturing technology continues to improve, has been widely in foreign countries Applications. After China's reform and opening up, especially in the 1990s, the rapid growth of the national economy, the public demand for information release increasingly strong, LED display just to adapt to the emergence of this market situation, and thus in the LED display design and manufacturing technology and application The level has been rapidly improved.
LED display has gone from monochrome, two-color graphic display, to the image display, until today's full-color video display development process. Regardless of the performance during the period (to improve the brightness of the LED display and blue light, etc.) and the composition of the system (computerized dynamic display system) and so have made considerable progress. Has now reached the level of ultra-high brightness full-color video display, can be said to meet the requirements of a variety of application conditions. Its application areas have been throughout the transportation, securities, telecommunications, advertising, publicity and other aspects. China's LED display development can be said that basically synchronized with the world level, has been formed with a considerable potential for development of the industry. It should be noted that China's LED industry not only in the application of technology has achieved great success, but also in the innovation capacity of outstanding performance. Compared with the rapid development of the domestic LED display industry, the current on the LED display of the book material is too small, not easy to design and manufacture of personnel and the use of maintenance personnel work, which germinated the preparation of a LED display technology with the idea , Coincides with the invitation of the University of Electronic Science and Technology Press, fighting the pen with grass on the book. The book on the LED display of the overview, LED display devices, graphic display, image display, video display and other related technical issues were described in order to engage in various types of LED display work readers from the book Get some useful material.
