LED display in the current large-scale stage lighting design is almost irreplaceable, as more and more LED application and popularization of the LED screen is also put forward higher requirements. Then this article will discuss the urgent need to address the major technical problems, attributed to "three high and one low", that is, high-efficiency, high color, high reliability and low cost of technical problems, low cost and its essence is a technical issue. Of course, to solve these technical problems still need to take a series of measures on all aspects of the LED display industry chain. Such as the use of new technologies, new structures, new technology, new materials. A wide range of applications: LED display because of light, color and other characteristics of pure supply LED bar night games, is widely used in building body contour, step, stand Bar Night LED manufacturers, bridges, hotels, KTV decorative lighting, as well as the production of advertising signs a variety of large-scale animation, painting advertising design and other places. Along with the LED display technology matures, its scope of application will be more extensive. 2, a small amount of fever: LED display light-emitting element is LED, because the single LED power is low, usually 0.04 ~ 0.08W, therefore not high fever. Can be used as decorative aquarium lighting, but does not produce a lot of heat caused by rising water temperatures, affecting the growth of ornamental fish. 3, Green: LED display its material composition of the material is used in environmentally friendly materials, are recyclable type, not because of the extensive use of the environment caused by pollution and destruction. 4, pure colors: LED display with high brightness SMD LED bar night games installed, so has the strengths of LED light emitting element, light color pure, soft, no glare. Both can be used as decorative purposes, but also cater to lighting purposes.
