PureDepth bought a patent for Multi-Layer 3D OLED displays

PureDepth announced today that they have acquired a patent for Multi-Layer 3D OLED displays. PureDepth Multi-Layer-Displays (MLD) use two or more displays that are placed one in front of the other to create 3D effects. These 3D displays do not require glasses and provide real depth.

One of the markets the PureDepth are targeting are mobile devices, and OLEDs are becoming more and more popular in that market. Up until now PureDepth had only LCD related patents, but now they can work on 3D OLEDs, too.
