1. What is a holographic stage?
The holographic 단계 is actually like a super powerful “magic stage”, which allows you to see the effect that seems to have come out of a science fiction movie.
In short, it uses a very magical technology to make virtual things seem to be really on the stage, and can also interact with real people.
Imagine that you have a mirror, but this mirror is not an ordinary mirror. It can record the shadow of an object, and it is a 3D shadow.
The holographic stage uses lasers as “brushes” to draw the shadow of an object (that is, the image) on a special film.
This process is a bit like taking a photo, but it is much more powerful than taking a photo because it can record the three-dimensional information of the object.
Then, when you shine a laser on the film again, you can see a three-dimensional virtual object floating in the air as if it is really there.
The performance on the holographic stage looks very cool. For example, on a stage, you can see a virtual singer singing, who seems to be on the stage but not really there.
He can dance and sing with real people and even interact with the audience. The audience will feel as if there are really two singers performing on the stage.
But in fact, there is only one real person, and the other is a virtual image projected by holographic projection.
Holographic stages are now used very frequently. For example, in some large concerts or evening parties, singers will use holographic projection to create surprises.
For example, a singer is singing on the stage, and suddenly, a virtual self appears next to him, and the two sing together.
In some activities with a strong sense of technology, the holographic stage can show virtual scenes, such as turning the stage into a starry sky or a mysterious forest.
The audience sitting in the audience will feel particularly shocked as if they have really entered another world.
In short, the holographic stage is like moving the scenes in science fiction movies into reality, allowing the audience to see things that they can’t see normally, which feels very fresh and magical!
2. Basic requirements of the holographic stage for LED display screens
1). Display effect requirements
The visual effect of the holographic stage must be very powerful. The LED display screen is like the “eyes” of the stage.
If the eyes are not good, the effect seen by the audience will be greatly reduced.
First of all, the screen must be clear enough. Just like watching a high-definition movie, every detail can be seen clearly, which requires high 해결.
Secondly, the lights on the stage are colorful, and the display screen must be bright enough to be seen clearly under strong light, and the contrast must be high, with clear black and white and bright colors, so that the picture can be more layered.
Furthermore, the screen 재생률 must be fast enough. Otherwise, the picture will be smeared when it moves; just like watching an old TV, the picture is blurred, and the audience will definitely not be able to stand it.
Finally, the audience may watch the stage from all angles, so the 시야각 of the screen must be wide enough, no matter where they are, they can see the complete picture, and there will be no limited viewing angle.
2). Environmental adaptability requirements
The performance environment of the holographic stage is not as comfortable as at home. Sometimes, it is outdoors, and sometimes, it is in a humid place, so the LED display screen must be “tough” enough.
First of all, waterproof and dustproof are necessary, otherwise the screen may be scrapped after a rain.
Secondly, the screen must be able to withstand high and low temperatures, otherwise it is easy to have problems in summer or winter.
Finally, if the stage environment is relatively humid or there are corrosive gases, the screen must have a certain degree of corrosion resistance so that it can be used for a long time.
3). Functional integrity requirements
The performance forms of the holographic stage are varied, and the LED display screen must be able to “master all kinds of skills”.
First of all, it must be able to play various content, such as high-definition video, pictures, text, and synchronize with music, otherwise the picture and sound will not match, and the audience will feel awkward.
Secondly, the screen should be remotely controlled, such as by adjusting the 명도 and switching the screen so that it is very convenient to operate on the stage.
If the screen can also detect faults by itself and automatically alarm when problems are found, it will be even more perfect.
These functions make the screen not only usable but also convenient and intelligent to use.
4). Stability and reliability requirements
The performance on the holographic stage cannot go wrong, and the audience is waiting to see the wonderful performance, so the LED display screen must be “reliable” enough.
First, the power supply system must be stable and cannot go on strike due to unstable voltage or overheating.
Secondly, the screen must have a good heat dissipation system. Otherwise, it will easily overheat after long-term operation, just like a computer will jam after being used for a long time.
Finally, it is best to have a backup system. In case of problems with the main system, the backup system can immediately take over, so that the performance will not be interrupted.
These requirements are to ensure that the screen can run stably on the stage without any accidents.
3. Which LED displays are suitable for use on the holographic stage?
1). LED 투명 스크린
This screen is like a transparent screen that can present a super-realistic three-dimensional scene.
It can perfectly integrate the virtual scene with the real stage background, and the audience is like being in a fantasy world.
For example, on the stage, it can project virtual characters or scenes and perform with real actors, and the effect is particularly shocking.
This type of screen has a particularly good display effect, high clarity, and strong stability.
It is particularly suitable for large-scale concerts, stage plays, or immersive exhibitions and can give the audience an immersive feeling.
2). LED curved screen
This screen is specially designed for stages that require curved surfaces, and it can present a more realistic holographic effect.
Its installation method is very flexible, and it can be bent at will according to the shape of the stage, and it can also be displayed clearly in places with strong light.
For example, on a circular stage, this curved screen can create a surround visual effect, allowing the audience to see super cool pictures no matter where they sit.
This screen is particularly suitable for commercial displays, stage decorations, or any holographic stage that requires an immersive experience.
3). Special-shaped LED display screen
This screen is like a “Transformer” on the stage and can be transformed into various shapes according to the needs of the stage design.
For example, curved screens, ring screens, cylindrical screens, spherical screens, and even stranger shapes are all possible.
This screen can bring super unique visual effects to the stage. For example, on a stage, a huge cylinder can be made of a special-shaped screen, and a holographic image can be played inside, which will be particularly shocking to the audience.
This screen is particularly suitable for performances that require creativity and visual impact, such as large concerts, stage plays, or immersive exhibitions.
4). 풀컬러 LED 디스플레이
This screen is like a “color master” on the stage, which can present colorful images and animation effects.
It has high contrast and brightness, can display 16.77 million colors, and the picture is particularly gorgeous and natural.
For example, on a stage, a full-color LED display can play ultra-high-definition videos with rich colors and clear pictures, which the audience will find particularly beautiful.
This screen is particularly suitable for various stage performances, such as concerts, music festivals, drama performances, corporate annual meetings, award ceremonies, exhibitions, etc., which can add a lot of color and vitality to the stage.
5). LED 렌탈 스크린
This screen is like a “temporary actor” on the stage. It is very flexible and can be quickly installed and disassembled as needed.
It has high brightness and can be seen clearly even in strong outdoor light. And it can be customized according to the needs of tenants, such as size, shape, and resolution.
For example, at a music festival, you can quickly build a super-large stage background with a rental LED screen, and it can be quickly disassembled after the performance, which is very convenient.
This screen is particularly suitable for temporary or short-term stage activities, such as concerts, music festivals, corporate activities, etc. It can provide high-quality visual effects and is relatively low in cost.
4. 주의사항
The holographic stage relies on visual effects. If the LED screen is blurry, the audience will definitely be dissatisfied. The resolution must be high for a clear picture.
The brightness must be sufficient, otherwise you can’t see anything when the lights are on.
The refresh rate should not be too low, otherwise the picture will be smeared when it moves, and the audience will feel dizzy.
The viewing angle must also be wide; otherwise, the audience will not see anything when looking from the side.
In short, the screen must be clear for the audience to see clearly so that the holographic effect can come out.
The LED screen of the holographic stage is quite difficult to install, especially those with strange shapes.
When installing, it must be stable, otherwise the screen will shake and the effect will be poor.
During debugging, the brightness, color, and contrast must be adjusted a little bit; otherwise, the picture will look uncomfortable.
Also, the screen should not reflect too much light; otherwise, the picture seen by the audience will be distorted.
In short, you need to be patient during installation and debugging, and don’t be impatient, otherwise you will not achieve the desired effect after a long time.
The price of LED screens for holographic stages is not cheap, especially those high-end ones. If the budget is limited, don’t spend money blindly on expensive ones, otherwise it is easy to overspend.
But you can’t buy poor quality ones to save money, otherwise the effect will not be good and the equipment will break easily.
You can use better screens in key locations according to actual needs, and ordinary ones in other places, which can save a lot of money.
If the event is temporary, renting equipment is also a good way to save a lot of expenses.
The LED screen of the holographic stage will heat up after a long time. If the heat dissipation is not good, the screen may overheat or even burn out.
Therefore, the heat dissipation system must be good, such as a large fan or heat dissipation holes.
Moreover, the environment on the stage is complex and the equipment is easily disturbed, so the stability of the screen is also very important.
It is best to choose a screen with protection functions, such as overheating, overvoltage, and overcurrent protection so that the equipment is safer to use.
In short, heat dissipation and stability are very important; don’t be lazy in this regard.
The performance environment of the holographic stage is various, sometimes indoors, sometimes outdoors, and even in humid places.
Therefore, the LED screen must be “tough,” and waterproof and dustproof functions are necessary. Otherwise, the screen will be useless after rain.
Moreover, the screen must be able to withstand high and low temperatures. Otherwise, it is easy to have problems in summer or winter.
If the stage environment is humid or there are corrosive gases, the screen must have a certain degree of corrosion resistance.
In short, when choosing a screen, you must base it on the actual environment. Otherwise, the screen may be “unsuitable.”
The LED screen of the holographic stage will also have problems after a long time, so regular maintenance is very important.
For example, the surface of the screen should be cleaned regularly; otherwise, dust will affect the display effect.
The cooling system should be checked regularly, otherwise it may not dissipate heat well; the circuit connection should also be checked regularly, otherwise it may become loose.
Moreover, with the development of technology, the software and hardware of the screen also need to be updated in time; otherwise, it may not keep up with the pace of the times.
In short, don’t think that everything will be fine after buying the screen. Regular maintenance and updates can make the screen last longer and have better effects.
5. 결론
The charm of the holographic stage lies not only in its visual impact but also in the carefully designed LED display screens behind it.
From transparent screens to curved screens, from full-color screens to rental screens, each type of display screen contributes to the magical effects of the stage.
