Points for attention in the installation of LED screens on the stage

In the previous stage performances, the function of LED was relatively simple, mainly to display video data and synchronize video images. In the stage performance at that time, stage workers did not include it in the category of stage art, but just regarded it as a big TV on the stage. Now, as an extension and supplement of stage performance, LED enriches the content of the performance and provides the audience with information beyond the performance itself.

At the same time, the audience got rid of a single and fixed perspective through the large LED screen, and could even see their own reactions, which also formed a certain sense of freshness visually. Stage LED large screen The stage LED large screen can divide a screen into multiple video screens for broadcasting. The display screens can be used independently, in combination, and in any combination to play related large backgrounds. The large screen can be displayed in partitions according to performance needs, and can realize graphic Superposition of text, background picture is played by video signal processor or synthesized into the same picture, close-up play of characters, text scrolling play, or interstitial play, video screen screen can be moved horizontally, and it can also be raised and lowered to become text, personality Video screen, brightening, beautifying the stage background and stage ground, through software design and system control to meet other requirements and advantages required by the owner, frame structure design can be adopted, easy to disassemble, reliable, easy to maintain and apply to various large entertainment venues and large-scale Activities. However, convenient technical means does not really mean high efficiency, and the comprehensive utilization of high-tech means on the stage does not represent a real improvement in the level of stage performances.

Let's discuss the taboos of using LED screens on the stage. The LED screen that only cares about the whole and ignores the parts. While many large-scale evening parties are held on the spot, most of them will put forward the need for live broadcasting through TV. At this time, the creative team of the party should not only consider the effect of the live performance of the party, but also take into account the communication characteristics of TV.

In the traditional stage art production, TV cameramen can find the background with low brightness or the background with large color difference in the background video as the background of the subject to achieve the unique artistic effect of the TV screen, but it is widely used in LED screens. Today, if the needs of the TV lens are not considered at the beginning of the design, the final picture will lack three-dimensionality, the main body of the picture and the background will easily fit and overlap, and the effect of TV communication will be greatly reduced. The basic constituent units of a TV screen are shots of different scenes, which in simple terms are panoramas, mid-shots, and close-ups, while live performances take into account more of the "panoramic" effect. Many creative teams often only consider the "big effect" of panoramic presentation when performing stage design and production, and lack of consideration for the middle ground, especially the close-up, needed for TV broadcasting.

Abuse of live-action stage LED display screens With the continuous upgrading of manufacturing technology, many production teams and organizers are fond of the "high-definition" feature of the screen, and it is easy to fall into the misunderstanding of "small loses big" in the creative process. In order to reflect the characteristics of the high-definition screen as much as possible, the producer is often keen to play a specially shot live video on the live video wall as the background dance. For example, in song and dance programs, a large number of images of urban landscapes and human life are played, in an attempt to combine the artistic interpretation of the program with the reality on the screen, but the result is counterproductive.

Stage performances pursue a high sense of form, with color, light, and formation at their core. However, most live-action videos have too many colors in the film. Using it as the main background of the stage will actually deduce the form of the stage program. It caused great damage, and caused the audience to have a sense of confusion of "can't see it" and "don't know where to look". The basic principles of stage design and production serving the program. Abuse of LED screens destroys lighting effects. The gradual reduction in production and use costs of LED screens has led many creators to blindly pursue the concept of "panoramic video dance beauty". LEDs instead. However, many creators ignore the reality that LED screens are likely to bring huge light pollution to the stage. When the stage is designed and produced, and the overall lighting synthesis is carried out, it is too late to regret.

In the overall design of the show, lighting plays a huge role. It can make the whole stage present a magical sense of space and layering, making the overall visual presentation richer and more interesting. In traditional stage design, the only source of light is the lighting system. The director, lighting engineer, and stage artist work together to create a unique stage space with light. .
