How does the 3D LED billboard work?

As we all know, our human brain is an extremely complex nervous system. Everything the human eye sees is three-dimensional. This is because a person\'s two eyeballs pass through a short distance between the human eyes, and they see two pictures with slight differences. This slight difference allows the brain to convert the spatial coordinates between objects into a straight line direction and the line of sight disappears. We can also use this feeling to distinguish the distance and size of objects, that is, the stereoscopic sense, that is, the stereoscopic sense.

The 3D LED screen takes the flexible LED screen that can be bent into a certain radian or 90 degrees as the hardware, and combines two images taken from different angles into one lens. When we view these images with the left and right eyes, parallax will occur, resulting in the depth observed in 3D technology.
