The large outdoor full-color LED display has become a new force in the media. The full-color LED large screen has always been an important part of the development of the LED field. It is an important part of the display of large-scale entertainment, sports events and squares. With the application of new technologies, new Outdoor advertising forms are constantly emerging, and outdoor advertising full-color LED display media is born.

At present, the world's demand for energy-saving, lightweight, miniaturized, high-reliability products is extremely urgent, and the LED display fully meets these conditions. LEDs are all-solid cold light sources that are smaller, lighter, and more rugged. They operate at only two volts and last for more than a decade. According to the usual definition of light efficiency, the luminous efficiency of LED is not high, but since the spectrum of LED is almost entirely concentrated in the visible light band, the efficiency can reach 80-90. LED display devices have been available for more than 20 years, due to the adoption and processing of raw materials. The upper limit is difficult to popularize in the first 10 years. After entering the 1990s, with the continuous improvement of the process and the development of raw materials, LED display devices have experienced rapid development in terms of lifetime and brightness indicators, and the cost has been greatly reduced.
