Displays
3D displays often utilizes special technology to present an image in 3D which requires no viewing glasses (called auto-stereoscopic). The dynamic approach utilizes a specialized 3d digital monitor to permit video, animation or slides shows. Alternate
approaches, such as lenticular or holographic, yield static, single 3D picture.
Some small consumer products/novelties have successfully incorporated
some 3D techniques for their markets. this might be used as an add-on to 3D
presentations.
Specialized Monitor - glasses free
Lenticular - A lens array covers the surface of an LCD screen to separate and direct left/right views for each viewer's eye. 3D view is free of any viewing glasses but has limited resolution and image depth (appearing as shallow images)
Twin LCD - Monitor is composed of two LCD panels, one over the other. In stereo mode the top panel is switched to a barrier screen or to act as a separate image depth. Monitor will as a regular screen with top LCD switched off.
Other - Some technological approaches, such as volumetric, have found limited markets
Specialized Monitor - viewer wearing glasses
Polarized - Some available technologies are twin LCD monitors with an overlaying splitter or using an active window covering the monitor screen to switch polarization for image view presented or polarizing individual LCD pixels separately. Simple polarized (sometimes circular polarized) glasses are use to view the 3D image.
Flicker - Viewer wears LCD glasses that actively opens left/right eye views with the image flipped between left/right view shown on the monitor. Common with virtual reality type applications. Can also be used with projection.
Static Displays
Printed lenticular have been used in poster size displays, back lit for most dramatic appearance.
Holograms have had limited success in presentation displays. Holograms are expensive to produce, limited size and color with severe lighting constraints on display.
