2. Polarized 3D system - Wikipedia

   en.wikipedia.org/wiki/Polarized_3D_system

   In the case of RealD 3D a circularly polarizing liquid crystal filter which can switch polarity 144 times per second [3] is placed in front of the projector lens. Only one projector is needed, as the left and right eye images are displayed alternately. Sony features a new system called RealD XLS, which shows both circularly polarized images ...

   Shutter glasses mostly eliminate "ghosting" which is a problem with other 3D display technologies such as RealD 3D, or Dual projector setups. Moreover, unlike red/cyan colour filter 3D glasses , LC shutter glasses are colour neutral, enabling 3D viewing in the full colour spectrum, but the technology has problems such as twinkle, vertigo, and ...

6. Autostereoscopy - Wikipedia

   en.wikipedia.org/wiki/Autostereoscopy

   Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D".
