In the past two years, the naked eye 3D LED display has frequently appeared, attracting everyone's attention with shocking and lifelike picture effects. In fact, the naked eye 3D LED display technology has been launched as early as 2012, but the actual application cases are not many, the lack of relevant technology and the lack of resources and application layout, is the biggest problem hindering the popularity of this technology. Today, follow Sunrise to explore the principle of naked eye 3D large screen to achieve visual 3D effects.

However, at present, with the application of LED display more and more widely, people's demand for creative display is getting higher and higher, two-dimensional flat display can no longer meet the growing demand, people want to be able to truly restore the real world of three-dimensional information, therefore, 3D display technology in the LED transparent screen application has become the focus and direction of research in recent years.

Then everyone will be more concerned about, how to achieve such a realistic 3D effect? As we all know, our human brain is an extremely complex nervous system, and anything that human eyes usually see is three-dimensional, which is because the two eyeballs see two pictures with subtle differences through the small distance between the human eyes, and this subtle difference allows the brain to convert the spatial coordinates between the objects in the direction of sight disappearance. We can also distinguish the distance and size of objects through this feeling, that is, three-dimensional sense, that is, three-dimensional sense of space.

To achieve the effect of naked eye 3D display, the cost is much larger than the theater wearing 3D glasses. At this stage, the LED large screen to achieve naked-eye 3D is actually mostly in the two-dimensional picture with the help of the object's distance, size, shadow effect, perspective relationship to build a three-dimensional effect. Just as we look at sketches, artists can use a pencil to create a three-dimensional image on a flat surface.

How to make a flat GIF 3D? Just make good use of the reference. We divide the ordinary image into layers by white lines, and then make the animation part "break" the white lines and cover the other elements of the layer, which can use the parallax of the eye to form a 3D illusion.
