In today’s stage performances, naked-eye 3D LED display screens have become a key tool to enhance visual effects.
But how can we ensure that these high-tech devices can play the best effect on stage? This article will reveal the key points to pay attention to when using naked-eye 3D LED display screens on stage.
جدول المحتويات
Item 1: Installation position and angle of naked-eye 3D LED display screens on stage
1). Reasonable layout of installation position
1.1). Select installation position according to منصة size and shape
For large stages, the main display screen is installed above the centre of the stage, about 5-8 meters high and about half the width of the stage, so that the audience can see clearly.
Auxiliary display screens are installed on both sides, with a 30-60-degree angle between the main display screen and the main display screen so that the audience on both sides can also enjoy the 3D effect.
For small stages, the main display screen is installed in the back background, 2-4 meters high and one-third to one-half the width of the stage.
Auxiliary display screens are small and can be installed on the pillars or walls on both sides.
If the stage is in an odd shape, such as a round stage, the main display screen is installed on the central upper bracket, and the auxiliary display screen is surrounded by a circle or arc along the edge to ensure that the audience can see the 3D effect from all angles.
1.2). Consider the coordination with other elements of the stage
When installing a naked-eye 3D LED display screen, avoid places where the light is directly shining.
Direct light will cause the display screen to reflect light, the picture will look blurry, and the colour will be inaccurate.
You can adjust the lighting angle or add an anti-reflective coating to the display screen.
At the same time, the سطوع of the display screen must match the brightness of the stage lighting; otherwise, it will be too bright and dazzling or too dim to see clearly.
During stage performances, the placement and movement of props must be coordinated with the position of the display screen.
For example, in a musical, if there is a large set of props moving on the stage, the display screen cannot be blocked by the props.
If the props must pass in front of the display screen, use a transparent display screen or a movable display screen.
When the props move, the display screen will adjust its position to ensure that the audience’s vision is not affected.
2). Determination of the best زاوية الرؤية
2.1). Determine the angle range according to the characteristics of naked-eye 3D technology
The naked-eye 3D LED display screen achieves a 3D effect based on the principle of parallax.
For the display screen with cylindrical lens technology, the best viewing angle is about 30-40 degrees in the horizontal direction and 20-30 degrees in the vertical direction.
For the display screen with light barrier technology, the best viewing angle in the horizontal direction is slightly narrower, about 20-30 degrees, and the vertical direction is similar.
Beyond these angles, the picture is prone to ghosting and colour distortion, and the 3D effect deteriorates.
2.2). Adjust the installation angle and position to expand the coverage range
The main display screen is tilted 10-20 degrees toward the auditorium so that audiences in different positions can see better 3D effects.
The auxiliary display screen can also adjust the tilt angle according to the installation position and the layout of the auditorium.
Changing the installation height and position of the display screen can also expand the coverage range of the best viewing angle.
For example, if the main display screen is appropriately lowered in height, both the front and back row audiences can see good effects.
The installation height and position of the auxiliary display screen are adjusted according to the slope of the auditorium and the distribution of seats so that the audience in different areas can be within the best viewing angle range.
Item 2: Hardware selection of naked-eye 3D LED display screen on stage
1). Display screen دقة و مساحة وحدة الصورة
High-resolution naked-eye 3D LED display, like the photos taken by a high-pixel camera, has a particularly clear and delicate picture.
However, the pixel pitch is also very important, which is like the distance between the “dots” on the screen.
The smaller the pixel pitch, the denser these “dots” are, and the clearer the picture is, just like the delicate pattern embroidered with fine stitches.
If the stage is large and the audience is far away, the pixel pitch can be slightly larger.
For example, P6 and P5 display screens are suitable for long-distance viewing, which can effectively control costs while ensuring the basic clarity of the picture.
If the stage is small and the audience is close, you have to choose models with a small pixel pitch, such as P2.5, P2, and P1.98.
The small pixel pitch makes the picture more delicate and allows the audience to see the details clearly.
2). سطوع and contrast of the display screen
The lights on the stage are varied, sometimes very bright and sometimes darker.
In such a complex environment, the display screen must be bright enough so that it can be seen clearly under various lighting conditions, and the details of the picture will not be unclear due to too strong light.
Imagine that if the picture is too dark, the audience will be looking at flowers in the fog and can’t see anything clearly. Therefore, a high-brightness display screen is very important.
Moreover, contrast is also critical. A display screen with high contrast can make the layering and depth of the picture more obvious.
For example, a high-contrast picture will make the black blacker, the white whiter, the transition in the middle will be more natural, and the 3D effect will be more realistic.
Choosing a display screen with high contrast can make the visual effect of the stage performance more shocking, leaving a deep impression on the audience and making them feel as if they are there.
Item 3: Video source selection for naked-eye 3D LED display screen on stage
1). Type of video source
There are many video sources to choose from for naked-eye 3D LED display screens used on stage.
If you want a good effect, a multi-viewpoint 3D video source is very good; it can be seen from different angles, and the three-dimensional sense is super strong.
There are also binocular 3D video sources that meet the BT.2160 specification, which are specially designed for 3D display and have great effects.
There are also (V+D) formats that can also be used on naked-eye 3D LED displays. Each has its own advantages.
2). Video source resolution
It is important to have a high-resolution video source, just like a photo with high pixels is clear.
High-resolution video sources can make the picture clearer and more delicate, and complex 3D scenes and details can be seen clearly.
If you can use a high-resolution video source of 4K or above, the clarity and immersion of the 3D effect will be greatly improved, and the audience will be more enjoyable to watch.
3). Video source compatibility
When choosing a video source, you also have to see if it is compatible with the naked-eye 3D LED display hardware.
Some video source formats are more special and may require special processing equipment to handle them.
These processing devices are compatible with video sources in multiple formats and can also be optimized according to the characteristics of the display screen.
So that the video source can present the best effect on the display screen.
4). Customization of video source
For specific scenes, such as stage performances, it is best to customize the video source.
You can plan the 3D effect of the video source in detail according to the theme, style and plot of the performance.
Item 4: Synchronous control of naked-eye 3D LED display on stage
1). Real-time synchronization with stage performances
When using a naked-eye 3D LED display on stage, the screen switching and animation effects must match the rhythm of the performance.
For example, when the music reaches the climax, the picture changes to a super shocking 3D scene or switches quickly to make the audience’s eyes light up.
If the music rhythm slows down, the picture becomes stable and soft, creating a corresponding atmosphere.
A professional synchronization control system can be used to connect the display screen with stage lighting and sound so that a perfect synchronization effect can be achieved.
For example, when an actor performs a certain action, the display screen can switch to the corresponding 3D scene synchronously, making the performance look more realistic.
2). Multi-screen linkage and coordination
If multiple naked-eye 3D LED displays are used on the stage, it is necessary to ensure that the images of these screens can be displayed and switched synchronously.
Use network communication technology to connect multiple displays to achieve multi-screen linkage.
When multiple screens are linked, pay attention to the splicing and transition effects of the images.
To make the entire stage image look coherent and natural, without obvious splicing marks, and without image delay, so as to ensure that the effect seen by the audience is perfect.
5. الخاتمة
Through the introduction of this article, I believe you have a clearer understanding of the key points of using naked-eye 3D LED displays on the stage.
Whether it is the careful layout of the installation location, the strict control of hardware selection, or the precise matching of video sources and the precise implementation of synchronous control, every detail affects the final stage effect.
