There are five kinds of LED display screens used in the Spring Festival Evening. The large display screen of rear projection has low resolution, but it is expensive. The two sides are better than the rear projection, although small, but not cheap. The most expensive is the floor, and the effect is comparable to that of a professional color discrimination display. In addition, the screen is protected by tempered glass (to prevent being trampled by actors), and the three-dimensional technology is even more scary. These lines need to be assembled separately. Estimate a ground screen12 ~140,000. If it is a top-level configuration, it is impossible to say 200,000 to 250,000, so the whole screen of the Spring Festival Evening will be 65,438.
