Introduction
With the rapid development of technology, traditional two-dimensional advertising can no longer meet people’s growing visual and psychological needs. As a new advertising display method, 3D LED advertising screens are gradually changing our understanding and experience of advertising.
3D LED advertising screens can use special technical means to give advertising content a three-dimensional visual effect, greatly enhancing the attractiveness and appeal of advertising.
1. Working principle of 3D LED advertising screen
3D LED advertising screens mainly rely on the principle of visual difference of the human eye. It uses sophisticated algorithms and special display technology to enable each pixel on the screen to produce different light and shadow effects, thereby simulating a three-dimensional effect.
When a viewer stands at a specific angle and watches, the left and right eyes will receive slightly different light, and the brain will fuse these lights to finally present a 3D visual effect.
For example, consider a simple 3D LED advertising screen displaying a sphere. The pixels on the left side of the sphere create one light and shadow effect on the screen, while the pixels on the right side create another light and shadow effect.
When your left eye sees pixels on the left and your right eye sees pixels on the right, your brain combines the two images into a three-dimensional spherical image.
2. The difference between a 3D LED advertising screen and a 3D full-series projection
In today’s visual technology field, 3D LED advertising screens and 3D holographic projections are eye-catching display methods. They both provide an immersive visual experience, but their working principles and characteristics are very different.
- Technical principle:
3D LED advertising screen: Mainly relies on liquid crystal display technology. Through special liquid crystal arrangements and optical elements, each pixel of the screen produces different light refraction and reflection, simulating a three-dimensional effect.
3D holographic projection: Using the principles of interference and diffraction. By recording and reproducing the light wave information of objects, the suspended display of holographic images is achieved.
- Display effect:
3D LED advertising screen: usually has higher resolution and color saturation, and the picture is clearer and more stable.
3D holographic projection: Presents a suspended, transparent visual effect, giving the audience a sense of a real three-dimensional space.
- Flexibility and application scope:
3D LED advertising screen: relatively more flexible, easy to install and move, suitable for various indoor and outdoor environments. Widely used in advertising displays, exhibitions, store windows, etc.
3D holographic projection: Rquires specific holographic materials and a larger space, and installation and maintenance are more complicated. Usually used in large-scale events, museums, performances, and other occasions.
- Cost and maintenance:
3D LED advertising screen: relatively low cost and simple maintenance.
3D holographic projection: The equipment cost is high and requires special maintenance and operation.
- Content production:
3D LED advertising screen: Content production is relatively simple, and existing 2D video production tools can be used.
3D holographic projection: Requires professional holographic content production technology and higher requirements for the production team.
3. Where is the 3D LED advertising screen suitable for installation?
3D LED advertising screens are different from other LED advertising screens. In order to present a better 3D effect, you should consider three points when choosing an installation location:
- Viewing angle restrictions:
In order to obtain the best 3D effect, the viewer needs to stand within a specific angle range. Beyond this range, the three-dimensional effect will gradually disappear.
Therefore, when designing and placing 3D LED advertising screens, it is necessary to consider the coverage of its viewing angle.
- Distance and clarity:
The distance between the viewer and the 3D LED advertising screen will also affect the three-dimensional effect. Generally speaking, the three-dimensional effect is strongest when the distance is moderate.
In addition, in order to ensure the clarity of the image, it is necessary to choose a high-resolution screen and a suitable viewing distance.
- Environmental factors:
Light and environmental factors will also affect the effectiveness of 3D LED advertising screens. An environment that is too bright or complex may interfere with viewing.
Therefore, when choosing a placement location, you need to take into account surrounding light and environmental factors.
4. What should you pay attention to when using 3D LED advertising screens?
- Whether the video source is high-definition:
First, confirm that the video source being played is 3D, and second, ensure that the video source provided to the 3D advertising screen is of high quality to obtain the best display effect.
The video source can be HD, 4K, or higher resolution 3D video. If the video source is not high-definition, the playback effect will be greatly reduced.
- Playback software:
There are also requirements for playback software because some playback software cannot play 3D video sources.
If the installed playback software cannot play 3D video sources, then the playback will not be 3D. So be careful when installing and choose one that can play 3D video sources.
Conclusion
When using 3D LED advertising screens, it is necessary to ensure that the advertising content has both visual impact and practical value and take the audience’s perspective into consideration.
Only in this way can the advantages and potential of 3D LED advertising screens be truly unleashed.
