A lot of autostereo solutions based on LCDs use lenticular screens or parallax barriers to present left and right eye views concurrently (this necessarily reduces the horizontal resolution by half). Most also have a very small sweetspot within which you must be positioned to see in 3D and do tend to suffer from Ghosting or double images unless you are not EXACTLY in the right viewing zone. Suggest www.stereo3d.com for an overview of what's out there in relation to LCD solutions and www.iris3d.com for very high resolution (UXGA and above) professional kit. The sharp system you mention is based on the parallax barrier approach and so does enable 2D/3D switching, but does suffer from low horizontal resolution (half-SXGA from memory) and has stereo-cross talk........but as said previously, this could be OK if you are looking for a quick review tool or presentation system - IMHO not a serious worktool for very high end stereo visualisation. The PLANAR system gets round the resolution issue by using 2 LCD panels, but does still use polarising glasses and so will suffer from cross-talk - It delivers SXGA resolution on a 17" image size.
