LED lights, driver ICs, power supplies, power signal connectors, and other materials are key factors that determine the quality of LED screens. Therefore, strict quality control must be applied when selecting materials, and relevant tests must be conducted with requirements higher than industry standards to verify the various functional requirements of LED screens.
Due to the special nature of stage LED rental display screens, high stability is required during operation. So every aspect of the system control scheme has a hot backup function, including video sending and receiving devices, signal transmission cables, etc. It can ensure that in the event of an unexpected situation in a certain part of the system, the system can automatically diagnose and switch to the backup device at an extremely fast speed, and the entire switching process will not affect the display effect on site. In terms of structural design, while ensuring the appearance and fashion of the box, it is also necessary to ensure good heat dissipation and fast splicing methods.
The previous section mainly discussed the design requirements for stage LED rental display screens. Now, let’s analyze the common usage misconceptions of stage LED rental display screens together.
1. The abuse of LED screens has disrupted the lighting effect that should be present in the stage performance area
The gradual reduction in production and usage costs of LED screens has led many creators to blindly pursue the concept of “panoramic video stage design”. LED rental display screens are widely used in stage design, and even replaced with LED rental display screens for all stage design scenes. However, many creators have overlooked the reality that LED screens can easily cause huge light pollution to the stage. By the time the stage is designed and produced, and the overall lighting is synthesized, they have already regretted it.
In the overall design of the program, lighting plays a huge role, as it can create a magical sense of space and hierarchy on the entire stage, making the overall visual presentation more rich and interesting. In traditional stage design, the only light source is the lighting system, and the director, lighting designer, and stage designer work together to create a unique stage space using lighting. But with the widespread use of LED screens, the situation underwent a huge change. In addition to the lighting system, various self luminous LED screens were also added to the lighting sources in the stage space. During the playback of various video materials, LED screens constantly change their luminous intensity and color due to changes in the picture. This characteristic makes the lighting control on the stage more complex, and the combination of light is also more challenging.
2. The abuse of real-life scenes leads to a huge conflict between video stage design and program content in terms of form
The continuous upgrading of LED screen manufacturing technology has made many production teams and organizers unable to put down the “high-definition” characteristics of LED screens, which can easily lead to the misconception of “losing the big for the small” in the creative process. In order to reflect the characteristics of high-definition screens as much as possible, the production team often likes to play specially shot real-life videos on the live video wall as background stage design. For example, in song and dance programs, a large number of urban landscape and cultural life scenes are played in order to achieve the combination of program art interpretation and screen reality presentation, but the result is counterproductive.
Stage performances pursue a high sense of form, with colors, lighting, and formations as the main focus. However, most live action videos have overly rich colors and use them as the main background of the stage, which can cause great damage to the formal interpretation of the stage program and create a sense of confusion for the audience, such as “not being able to see” and “not knowing where to look”. The design originally intended to enhance the program effect ultimately has a huge impact on the audience’s viewing and violates the basic principle of stage design and production serving the program.
