LED 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 life, flexible configuration, rich color and the ability to adapt to indoor and outdoor environment, since the late 1980s, with the continuous improvement of LED manufacturing technology. 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.
LED display system composed of LED display system is a computer-specific equipment, display screen, video input port and system software and other components.
(1) computer and special equipment: computer and special equipment directly determines the function of the system, according to the user's different requirements of the system to choose a different type.
(2) display screen: the display of the control circuit to receive the display signal from the computer, driving LED light to produce the screen, and by increasing the amplifier, speaker output sound.
(3) video input port: to provide video input port, the signal source can be a video recorder, DVD player, camera, support NTSC, PAL, S Video and other standard.
(4) system software: to provide LED player dedicated software, PowerPoint or ES98 video playback software.
