Lcd pj 3d fp??

The real 'issue' with LCD and LCoS front projectors comes down to the true time required for the display chips to completely switch between the two images (i.e., the true response time for 100% transition of a given pixel between any two values). LG with their announced 3D LCoS projector gets around this by using two complete light engines thus allowing each set of LCoS display chips to handle only the right or left video stream. Samsung attempts to get around the response time limitations of their flat panel 3D LCD HDTVs by refreshing at 240Hz and inserting black frames between each video frame. Even then these displays show some crosstalk (ghosting) between the right and left image streams this is probably being caused by inadaquate response time and the LCD flat panel 3D HDTV that Sony is displaying at their Sony Style store has even worse crosstalk. So the bottom line is it is not yet known, if the manufacturers can actually advance the technology such that they can build next generation LCD and LCoS display chips that have low enought response time to prevent crosstalk between the right and left images when displaying 1080p/60 (or higher refresh rates) to each eye. Epson in particular is the key manufacturer for LCD technology, since they also make the LCD display chips used by Panasonic, Mitsubishi and perhaps others. For LCoS it is Sony and JVC since they manufacturer the display chips used by all of the consumer LCoS projectors.

DLP on the other hand can easily switch between the right and left image streams without any response time isssues.

I really do expect to see moderately priced DLP 1080p 3D projectors available toward the end of 2010. In the case of DLP the additional cost to add 3D capability is quit modest (basically just upgrading the HDMI and video processing chips plus adding a IR emitter to sync. the shutter glasses and perhaps a higher wattage lamp). Today's mid-level 1080p DLP projectors with a street price in the range of $2.5K might evolve into 3D models with street prices in the $3K range, but some manufacturers may decide to first offer 3D only in their highest-end model(s). As for LCD projectors this year, there certainly could be models offered using dual light engines (but they would be expensive) using existing LCD display chips, but single light engine models that can actually project 3D without right/left crosstalk may still be a year or more away. You do need to remember to using alternating right/left images in combination with shutter glasses reduces the viewed image brightness by 70% to 85% and depending on the screen size and screen gain a much higher wattage bulb may be necessary to keep image brightness to an acceptable level for 3D viewing. For example my Epson 6500UB is considered a fairly bright HT projector, but once calibrated I find it doesn't have very many lumens to spare when projecting onto a 120" 16x9 screen with a gain of 1.1. Such a projector with its current light engine lumens would probably only provide adequate brightness for 3D viewing if used with a screen of less than 80" (and perhaps 60") or substantially higher gain. I suspect many future moderate priced 3D projectors may attempt to support 3D by essentially running the projector in a vivid or dynamic mode where then can produce higher lumens, but not achieve good color accuracy.

i just hope that the 1080p projectors can use the non mandatory formats in the new 1.4a specs- or even better just the old 1.3 format but in 1080p 120hz for the PC 3d. i was pretty bummed the new 3d tvs can only game at 720 on consuls and the PC! Nvidia hardware can run 1080p 3d but they are not even supporting it for the 1.4a 3d tvs because none of them come with 120hz 1080 3d PC gaming options. This is a step backwards for me.

its strange that everyone talks about the 3d darkening the colors- for me the only thing i notice with 3d on is how much better the colors look compared to 2d. colors have a better feel to them- like added depth. maybe i just don't have as discerning of a eye as most users. im using the Mitsubishi tv and nvidia 3d vision on a pc.

im really looking forward to a true 1080p 3d projector on a huge screen!
