Principle of Naked Eye 3D LED Display Technology

With the wider and wider application of Outdoor Led Display, people's demand for Creative LED Digital Signage is getting higher and higher, the 2D plane display can't satisfy the growing demand, and people would like to realistically restore the 3D information of the real world, therefore, the application of Naked Eye 3D Led Display on the LED transparent screen has become a hot research topic and direction in recent years. Therefore, the application of Naked Eye 3D LED Display in DOOH LED Display Screen has become the hot spot and direction in recent years.

Naked Eye 3D LED Display allows viewers to directly enjoy realistic 3D images without the use of 3D glasses. The basic principle of this technology lies in the precise projection of pixels corresponding to the left and right eyes into the viewer's left and right eyes respectively, a process made possible by the application of the parallax principle to create a three-dimensional visual image.

In fact, the origins of 3D technology can be traced back to the Renaissance concept of "optical illusion". Humans are able to perceive depth because of the difference in visual information received by our eyes. When we look at a picture or object, there is a difference in the content of the image received by the left eye and the right eye. This difference is even more pronounced when we close one eye, because the left and right eyes see things in different positions and at different angles.

Naked 3D technology takes advantage of this binocular parallax to produce a 3D stereoscopic effect by means of a technique known as the parallax barrier. This technique relies on the brain processing the different images received by the left and right eyes to create a sense of depth. In front of a large screen, a structure consisting of an opaque layer and precisely spaced slits projects pixel dots from the left and right eyes into the corresponding eyes. This process is realized by means of an elaborate parallax barrier, which enables the viewer to perceive the three-dimensional image clearly without the need for any auxiliary equipment. The use of this technology not only enhances the viewing experience, but also advances the development of display technology, opening up new possibilities for future visual entertainment and interaction.

Currently, the common Naked Eye 3D LED displays are Rounded corner Naked Eye 3D LED Display, Right-angle type Naked Eye 3D LED Display, XR virtual LED display backdrop, 3D Hologram Display Wall, and so on. Hologram Display Wall, Black leds Naked Eye 3D LED Display.
