The outdoor naked-eye 3D led screen has excellent pictures, which can quickly attract passers-by on the streets. Therefore, the 3D LED video walls in various places have attracted many tourists to take photos, which invisibly achieved the purpose of advertising.
Of course, any amazing display effect is inseparable from the support of technology. Next, we will reveal how this magical 3D display effect was born.
1. The Working Principle of Naked eye 3D LED Display
Essentially, the naked-eye 3D screen utilizes the parallax feature of the human body. There is a certain distance between human eyes. So when we look at an object, each eye has two viewpoints.
When the left and right eyes receive pictures from different positions, the brain defaults that they should overlap and merge. Therefore, the image has a three-dimensional effect and a sense of space.
Indoor/outdoor 3d led screen makes use of people’s visual illusions. With the help of a unique screen installation scheme, the audience can feel the virtual existence in real life.
A normal outdoor 3d LED display consists of two screens with a 90° angle. When the audience stands at the corner of the two screens, they can see the content of the two screens at the same time. With specific animation materials, it can create a strong sense of atmosphere.
2. Why is the naked-eye 3D LED Display popular?
Unlike VR and AR, which require additional equipment to achieve corresponding virtual effects, people do not need to use any equipment such as 3D glasses. The naked-eye 3D led screen allows people to see three-dimensional images with the naked eye.
Glass-free led display is not a new product, but it has gradually become popular in the past two years. In March 2020, an artwork named Wave was unveiled at the SM Building in South Korea. The curved display screen with creative 3d led content and the virtual and real visual effects make people feel novel about it. Subsequently, 3d outdoor led displays quickly became popular and appeared on the exterior walls of commercial buildings in major cities.
There are two reasons for the popularity of naked-eye 3D LED display: its shocking and realistic display effect and the increased marketing investment of advertisers.
Advanced 3D led technology, high-definition high refresh rate led display, customized creative 3D content. The birth of high-quality naked-eye 3D LED displays is inseparable from their help.
High-quality led display has more advantages than traditional banners and slogans in advertising. The naked eye 3d led video wall is more attractive than the traditional two-dimensional led display because of its unique 3D display effect. Therefore, more advertisers have seen its excellent advertising capabilities and increased investment costs. It also allows more people to see the charm of 3d display technology.
3. Analysis of 3d display technology
3D display technology makes the picture three-dimensional and realistic, allowing the audience to feel immersive. 3D technology is divided into two categories: glasses type and naked eye type.
Glasses-free 3D LED Video Wall
Glasses-free 3D technology currently has two major application fields. One is the naked eye 3D led display large screen. In busy streets and other places with large traffic, it is generally used for outdoor publicity to enhance the image of the city.
3d LED video wall is also an excellent advertising medium, which is sought after in major shopping malls, exhibition halls, museums, virtual productions, stage performances, and other fields.
3D LED hologram fan
3D led hologram fan is a product derived from holographic projection technology. From the outside, the holographic fan has two blades. This is a led light strip with a protective cover installed. It gradually forms a continuous and complete image through high-speed rotation, and the image has a three-dimensional effect.
At present, 3D LED hologram fans are working in product display and advertising media fields. It can satisfy the playback of 2D and 3D video. It is suitable for displaying individual items with rich details or internal structure, such as watches, jewelry, etc.
With the advancement of naked-eye 3D display technology, 3D led display screen will surely bring us more surprises.
Glasses-based 3D technology
In glasses-based 3D technology, there are three main types: chromatic aberration, polarized, and active shutter. The 3d anamorphic display technology has a simple imaging principle and has the longest history.
4. How to achieve a stunning 3D display effect?
How to get a perfect outdoor 3D LED billboard? To make a beautiful outdoor naked eye 3D LED video wall, you need to consider the following key factors:
High-quality 3D led display
From the aspect of picture quality, the picture of the led display panel with high-definition pixels, high contrast, and HDR is more realistic and delicate, and the video picture conversion is smoother. The naked-eye 3D LED screen with high grayscale and high refresh rate can achieve more realistic 3D effects.
In terms of safety performance, and high reliability, a thin and light outdoor led screen cabinet is necessary. Due to its large area, the load-bearing capacity of the building is crucial.
In addition, the outdoor giant led screen with efficient protection measures can better cope with bad weather. High waterproof, windproof, and shockproof ability will be necessary.
suitable viewing position
Firstly, considering the capital investment of display screens and creative materials, outdoor naked-eye 3D LED video walls are generally built in the center of business districts, intersections, squares, and other places. Its purpose is to expand the coverage of the display.
Secondly, the corners are the best viewing positions. Many solutions make the screen curved at the corners. Human eyes accept the content presented by two screens at the same time, and coupled with the visual difference, the most perfect naked-eye 3D effect can be presented.
Excellent creative 3D content
In addition to hardware equipment, video footage is also important. The video content is rich and colorful, including ocean waves, spaceships, animals, etc. If the video content has special effects such as smoke, water droplets, particles, etc., the price will be higher. The cost of video production is generally billed by the second.
