1. Why does the stage like to use an LED display?

The reasons why the stage likes to use LED display can be summarized as follows:

1). High brightness and high contrast

Adapt to a strong light environment:

The light on the stage is usually very strong. The LED display, with its high brightness and high contrast characteristics, can ensure the clear visibility of images and text in this environment. This is an advantage that traditional projectors and LCD screens cannot match.

2). Free splicing and flexibility

Modular design:

The LED display adopts a modular design, which can be flexibly spliced according to the size, shape, and layout requirements of the stage to form display screens of various shapes and sizes. This flexibility enables LED displays to adapt to a variety of complex stage scenes and performance requirements.

Seamless splicing:

LED displays can achieve seamless splicing, presenting more vivid and lively visual effects and providing audiences with a more coherent and immersive viewing experience.

3). Energy saving and environmental protection

Low energy consumption

Compared with traditional display devices such as TV walls and projectors, LED displays have lower energy consumption, which helps reduce the operating costs of stage performances.

Environmentally friendly:

LED displays are pollution-free and environmentally friendly, in line with the modern stage performances’ pursuit of green and environmental protection.

4). Wide viewing angle

Large viewing angle range:

LED displays can achieve a larger viewing angle range, ensuring that the audience can clearly see the content on the screen no matter where they are on the stage. This is crucial to improving the audience’s viewing experience.

5). Long life and low maintenance cost

حياة طويلة:

LED displays have a long service life, reducing the frequency and cost of replacing equipment.

Low maintenance cost:

LED displays have relatively low maintenance costs and are easy to repair, reducing the downtime and operational risks of stage performances.

6). High fidelity and rich colors

High fidelity:

LED display screens can present more realistic and vivid colors and images, enhancing the visual effects and artistic appeal of performances.

Rich colors:

Through the combination of red, green, and blue primary color LEDs, LED display screens can present rich colors and delicate picture effects, meeting the high color requirements of stage performances.

7). Integration of creativity and new technologies

Creative design:

Experienced stage designers will combine the content of the script and the performance requirements and use the “creative” design of LED display screens to bring surprising stage performance effects.

Integration of new technologies:

The integration of LED display screens with emerging technologies such as stage machinery, robotic arms, and projection can better help the realization of “creativity”, making the stage more exciting, more explosive, and more impactful, bringing a shocking visual experience to the audience.

2. How do you design the stage LED display screen?

The design of the stage LED display screen needs to take into account multiple aspects to ensure that it performs best on the stage. The following is a clear design framework covering the main design points and reference information:

1). Size and resolution

Size selection:

Determine the appropriate size of the LED display screen according to the size and layout of the stage. Ensure that the audience can clearly see the content on the screen at different positions.

Considering the audience’s viewing angle and distance, choose the right screen size to provide the best visual experience.

دقة:

High resolution is the key to improving the fineness and clarity of the picture. Choose a resolution that suits the stage needs to ensure a clear display of images and text.

Common stage main screen resolution specifications include P2.97, P3.91, P4.81, P6.25, etc. The specific selection needs to be determined according to the stage size and audience distance.

2). Brightness و contrast

High brightness:

The light on the stage is usually strong, so the LED display needs to have sufficient brightness to ensure that the content is still clearly visible in a strong light environment.

High contrast:

High contrast can enhance the layering and detail expression of the image, making it easier for the audience to distinguish different elements in the image.

3). زاوية الرؤية

The LED display should have a wide viewing angle to ensure that the audience can clearly see the content on the screen no matter where they sit.

During the design process, it is necessary to test the visual effects at different angles to ensure that a high-quality visual experience can be obtained throughout the auditorium.

4). Installation location and structure

موقع التثبيت:

Choose a suitable installation location according to the layout and design requirements of the stage. Avoid blocking other important elements of the stage and ensure that the audience can see the screen content from all angles.

For large stages, multiple display screens may need to be set up to meet the needs of audiences in different areas.

Installation structure:

The stability of the installation structure is crucial. It is necessary to ensure that the bracket can withstand the weight of the display screen and external factors such as stage vibration and wind.

Taking safety factors into consideration, relevant safety regulations and standards should be followed during the installation process.

5). Modularity and flexibility

The modular design enables the LED display screen to be flexibly spliced into various shapes and sizes. This helps to adapt to changes in different stage scenes and performance requirements.

The modular design also facilitates the maintenance and replacement of faulty modules, reducing maintenance costs and downtime.

6). Intelligent control and interactive technology

Integrate intelligent control systems to realize functions such as real-time video processing and dynamic content mapping of LED display screens. Improve the visual effects and interactivity of the performance.

Consider integration and control with other stage equipment (such as lighting, sound, etc.) to ensure the coordination and consistency of the entire stage performance.

7). Content Creativity and Motion Effects

Make full use of the characteristics of LED display screens to design creative and dynamic images, videos, and animation effects. Match with the performance content to enhance the audience’s viewing experience.

Consider the audience’s interactive needs, design interactive links and interactive effects, and enhance the audience’s sense of participation and experience.
