What is 3D digital signage?
Autostereoscopic 3D, or “without glasses” is created by interlacing two channels of the same content which are set slightly apart from each other. In the past, this was done by using the de facto red and blue glasses. Now, special barriers are being placed over screens that do the interlacing for the viewer, thus negating the need for glasses. PHOTO GALLERY: Provision 3D digital signage installations This can be done in one of two ways. The more primitive of the two is the parallax barrier, which is a fixed barrier with a foil mounted between two pieces of glass, and then paired up exactly with pixels. Lenticular is a barrier with edged grooves which split the light, magnifying different images when viewed from different angles. Zerega said that parallax barrier technology has been around for awhile, but increases in the use of LCD screens for digital signage is resulting in more use of lenticular technology. “Parallax barrier lens is like putting a screen door in front of the LCD scre
