LED screen application in stage art design

The abbreviation of the light emitting diode in English is LED, which means light emitting diode in Chinese, and its shape is capsule-shaped. The energy is released through the recombination of electrons and holes to form light-emitting points, and the light-emitting surface is obtained by the arrangement and combination of many light-emitting points, that is, the LED display screen. It can display characters, images, animations, and videos by controlling the brightness and color of the light-emitting points. The smaller the spacing between the light-emitting points, the higher the resolution of the LED screen. The large LED screens seen in daily life, such as TV parties, large-scale performances, etc., are giant display screens connected by many LED screens. Differences are based on the usage environment, display color, display performance, etc. The LED display is divided into indoor, outdoor, semi-outdoor, single primary color, dual primary color, full color, interactive screen, glass screen, transparent screen, and other categories.

The application of LED screens in stage art design can greatly expand or extend the visual space of the stage, break the restrictions of the closed stage, realize multi-scene and multi-level stage visual effects, broaden and enrich the stage performance, and how many things that cannot be actually presented on the stage. It creates a three-dimensional immersive stage environment that is both real and fantasy. The characteristics of LED screens are that they are easy to disassemble and assemble, and can be assembled into various shapes. Using LED screens during performances can save stage production costs and effectively avoid the disadvantages of traditional stage art design, which is time-consuming, labor-intensive, and difficult to recycle.

LED components appeared as early as 1962, with low luminosity in the early days, and were mostly used for indicator lights and display panels. In the mid-1980s, LED began to enter a stage of rapid development, and high-brightness, full-color LED screens came out one after another. LED screens are widely used in park squares, party scenes, stadiums, and other occasions. But initially limited by computer digital technology, the LED screen can only show simple advertisements and animations on the stage, and the stage visual effect is very limited. Entering the 21st century, with the development of computer information network technology, many fantastic and magnificent images can be implanted on the stage through LED screens, which has profoundly changed the way of traditional stage scenery. As an extension and supplement of the stage performance, the LED screen not only enriches the content of the performance. It provides the audience with information about the performance itself and uses virtual pictures to create a more atmospheric imagination space for the audience. LED screens have gradually become an indispensable part of modern stage design. Stage performance cooperates with traditional stage art techniques and complements each other, so that stage designers realize the importance of “artistic packaging” for performances.

Combination style of LED screen

According to the shape of the LED screen and the position on the stage, the LED screen can be divided into the main screen, the secondary screen, the ground screen, the ladder screen, the ring screen, the U-shaped screen, and the screen column. Usually, the main screen in the center of the stage should use a high-resolution LED display with clear imaging, and the screens in other positions can be appropriately reduced according to the cost and budget. The LED screen in the field of stage design can have a variety of combination styles, such as the large-screen shape with the highest frequency, which consists of the main screen supplemented by many sub-screens to build a panoramic performance space. At present, most of the theaters in our country are frame-type stages. Only a background screen is set at the back of the stage. The front audience can get an excellent viewing effect, but the audience on both sides may see the actors stray from the LED screen display background. The panoramic large-screen shape can effectively solve this problem and surround the audience as if entering the scene presented by the screen.

In order to fit the theme of the performance, the most typical image is the annual CCTV Spring Festival Gala. The theme of the 2017 CCTV Spring Festival Gala is “Symbiosis, Harmony and Inclusion”. The top of the stage is composed of auspicious clouds and a five-ring screen with multiple ring screens and screen pillars. ” the warm feeling that all Chinese are part of the Chinese nation. “Auspicious Clouds” symbolizes the luck of the country, family, and people. It perfectly interprets the theme and won unanimous praise from the audience. In addition, in order to pursue special stage visual effects, LED screens can also adopt repeated shapes, balanced shapes, irregular shapes, etc. For example, the stage background of the variety show “I want to sing with you” is composed of dozens of LED screens arranged in an arc. , each screen shows a person singing, with the cumulative effect of repeated modeling, giving the audience a strong visual impact. However, due to the overly complex and changeable way of use, blindly pursuing the grandeur of the scene and the unique elements of the stage art will make the audience dizzy, unable to concentrate on the performance of the actors, and it is easy to fall into the misunderstanding of “overwhelming the guest”, which requires stage designers In the early design, the overall effect of the performance is considered in all aspects, so as to delete or superimpose.

The combination of LED screen and light

The main task of traditional stage lighting design is to ensure that the stage has a suitable basic illuminance. On this basis, the brightness contrast of the lighting is used to control the level of contrast between the performers and the set props, as well as the harmony and unity of the overall color change of the stage. The empty and dark parts left by the traditional stage scenery need to play the role of lighting, or the bright or dark lighting and the bright scenery form a combination of true and false, mutually beneficial and complementary connection, from point and line to surface, space Full of feeling.

But nowadays, after LED screens are widely used in stage background design, many stage designers blindly pursue the splendor of visual stage beauty, thus abandoning the cooperation of traditional sets and only using LED screens for presentation. However, because the LED screen has its own light source, and the displayed digital image content is constantly changing with the progress of the program, the brightness and color are also constantly changing, which has a huge impact on the original lighting design. As a result, when the overall lighting integration rehearsal was finally carried out, it was found that it was easy to conflict with the lighting design on issues such as light and shade matching, color jump, actor lighting, and layer matching.

For example, when the light intensity of the LED screen is too high and the background is too prominent, it will cause insufficient illumination on the performer’s face, darkening and graying. When the LED screen fills every corner of the stage without leaving any empty black part, although the visual picture created is very beautiful, the arrangement of “full” will affect the effect of the lighting. If the brightness of the LED screen is too low, the audience will not be able to see the content of the screen clearly, resulting in unsatisfactory effects on the level, tone, and clarity of the screen, which in turn affects the overall stage design. It even affects the presentation of the program.

Therefore, stage designers should change the concept of stage lighting design. On the one hand, they should balance the light source of lamps and the illuminance and color temperature of LED screens. On the other hand, it is also necessary to control the brightness and color of the performers and the screen background and change the design concept of the dance video. The author believes that in practice, we can discuss and analyze the performance environment by integrating the rehearsal before the performance or even before the stage design through team cooperation. First of all, the LED screen should be considered as a part of the stage lighting, and the average brightness of the LED screen and the color of the screen should be inspected and adjusted as a whole. Furthermore, the brightness and color of the digital image content displayed on the LED screen are adjusted in combination with the arrangement of the program. Make appropriate adjustments to the stage lighting to ensure that the light ratio between the screen and the light is kept within a moderate range, without hindering the presentation of their respective artistic concepts. At the same time, it is also necessary to pay attention to the combination of the LED screen image and the color of the light and to deal with the fusion of the same color system and the contrast of different color systems. Avoid mixed colors on the stage and weaken the effect of the program. In addition, try to ensure that the change of the LED screen material picture is in line with the change of the light. Create a corresponding performance environment according to the specific emotions of the characters in the plot or the characteristics of the character image. Fully stimulate the audience’s imagination, and let the audience into the program.
