In the past two years, naked-eye 3D LED displays have appeared frequently to attract everyone’s attention with shocking and realistic picture effects. In fact, naked eye 3D LED display technology has been launched as early as 2012, but there are not many actual application cases, the lack of relevant technology and the lack of resources and application layout is the biggest problem that hinders the popularity of this technology. Today, we will follow the editor of Hengcai Optoelectronics to explore the principle of naked eye 3D large screen to achieve visual 3D effects.
However, at present, as the application of LED display is more and more extensive, people’s demand for creative display is getting higher and higher, two-dimensional flat display can no longer meet the growing demand, people prefer to truly restore the real world of three-dimensional information, therefore, the application of 3D display technology on LED transparent screen has become a hot spot and direction of research in recent years.
Then we will be more concerned about how to achieve such a realistic 3D effect?
It is known that our human brain is an extremely complex nervous system, the human eye usually see anything is three-dimensional, this is because the two human eyeballs through the small distance between the human eye interval, see two pictures with subtle differences, this subtle difference so that the brain can be in the direction of the disappearance of sight to convert the object between a spatial coordinates, we can also be able to distinguish the object through this sense of distance and size, that is, three-dimensional sense, that is, three-dimensional sense of space.
Display screen to achieve the effect of naked eye 3D, the cost is much larger than the theater to wear 3D glasses. At this stage of the LED screen to achieve naked eye 3D is in fact most of the two-dimensional picture with the object’s distance, size, shadow effects, perspective relationship to build a three-dimensional effect. As if we look at sketching, painters can use a pencil to draw on the plane to create a false three-dimensional image.
How to make a flat motion picture produce a 3D effect? Simply by using a good reference. We divide the ordinary picture into several layers by white lines, and then make the animation part can “break” the white lines and cover the other elements of the layers, so that we can use the parallax of the eyes to form the illusion of 3D.
