In recent years, LED display technology has developed rapidly, and the technical level and maturity of LED display devices are getting higher and higher, and the fields and contents involved are more and more extensive. Put on the stage of today's TV art show, represented by CCTV Spring Festival Evening, the most dazzling is a variety of LED display , based on elaborate holographic pictures and dynamic video pictures, from the stage The left and right directions and positions are nearly seamlessly stitched together to form a nearly perfect enclosed space, complemented by hundreds of mechanical lifting stages, showing an unprecedented picture for the audience in front of the TV. The dynamic and realistic picture brings great impact and enjoyment to the audience visually. The development of LED display technology has brought great convenience and change to today's beauty designers: on the one hand, it has greatly changed the creative concept and creative habits of designers, and has become the most expressive and most eye-catching on the stage. On the other hand, it extends the design field of the creative staff from the original stage top to all directions. The real point, line and face are filled with artistic cells, with advanced AR technology creates an artistic atmosphere between the real and the illusory. As a TV worker who grew up from the stage of the "Original and Simple" in the Spring Festival Evening in the 83rd Spring Festival to the colorful holographic LED space of the Spring Festival Evening in 2013, personally, it is no exaggeration to say that the performance of the LED screen is CCTV Spring Festival Evening. The most gorgeous and successful technological advancement on the stage of the 30th Spring Festival Gala. (Figure 1) 
The LED picture design represented by "Spring Blossoms" is quite perfect.
In the face of such a luxurious and spectacular scene, the person who works as a grass-roots TV station is really confused. It’s a joke, maybe the attitude of the fox who can’t eat the grapes is blaming. After watching the Spring Festival Evening in 2012 and 2013, I suddenly had a disapproval of the use of LED screens on such a large scale. As for the stage of the Spring Festival Evening in the past two years, the use of LED screens is slightly excessive. Why do you say this? It is mainly based on the following reasons:
First, the use of LED screens is suspected of taking the initiative
Looking back at the history of LED screen used in CCTV Spring Festival Evening, the first use of LED screen was in 1993, limited by the technical conditions at that time, its existence is more of a technical means of displaying video materials and image data, LED screen and dance beauty The degree of integration is almost zero, basically free from the beauty design and program, just like a solitary propaganda bar on the street. In fact, the use of LED screens in the art programs of most TV stations (especially local stations) is still this model. Since the 2008 Olympic Games, CCTV has used a large number of new LED multimedia displays, and hired a three-dimensional animated background design with the Olympic opening stage background design, which truly integrates the LED screen into the beauty and program content; from 2012 At the beginning, the LED screens, which were originally in the form of sheets and walls, were installed in a multi-dimensional manner, and a so-called holographic LED screen was formed with holograms and stage machinery. Computer CG creation and stage mechanical movements were compiled according to the program content. The entire stage is beautiful, just like a fairyland, so that the LED screen has reached an unprecedented level and height in the production of the program. As a result, this brings the first question. What is the relationship between the LED screen and the content of the program? Is it subordinate to program content or higher than program content? First of all, we can't cover up some of the content of the program because of its super expressive power. After all, the LED screen is only a part of the beauty of the dance. Its role is to set off the program instead of robbing the movie. It is like the over-packaging of mooncakes for the Mid-Autumn Festival. This kind of problem is especially prominent in song and dance programs. For example, in the spring of 2013, Na Ying’s "Spring Blossoms", to tell the truth, I really didn't hear how good this song was, but I felt it when I listened later. It was a very good song. The reason for this is that I was attracted by the pictures at the time and distracted the attention of the song. In recent years, it has been said that there is no good song in the Spring Festival Evening, and the lack of creativity is one aspect. On the other hand, there are too many distractions on the stage, which makes it impossible for people to concentrate on enjoying the program. impression. The entire Spring Festival Evening Song and Dance program is more like Hollywood's sci-fi blockbusters. It is easier for people to remember the wonderful action pictures and the attention to the content is significantly reduced. Therefore, the author believes that although the picture brought by the LED screen is so desirable, it must not be inverted. Otherwise, the final result of the whole program is like buying a bead.

This picture gives me much more impression than the song itself. Sometimes too prominent details often affect people's subjective choices.
