It’s been suggested that customer bewilderment over and dislike to wearing 3D glasses have been among the most important inhibiters to 3D TV purc
That’s the question that was repeated by many observers walking the aisles of the big trade show.While some of the big studs, including Panasonic and Sony, stuck to their guns by introducing secondgeneration 3D TVs using active-shutter glasses, LG, Toshiba and Vizio introduced new 3D lines using passive glasses technology as well as new lines based mostly on the active-shutter glasses system. Samsung, in the meantime, in addition to showing second-generation active-shutter glasses sets, announced it is jointly developing with RealD ( the developer of 3D systems for film theaters ) a new compound system based primarily on RealD’s RDZ technology that for absence of a better term is active/passive.The new system also uses an active-shutter mechanism, but the shutter system is placed in the TV rather than the eye glasses.
Samsung and other manufacturers will choose the active- shutter-less 3D glasses approaches that produce better results and don’t halve the display resolution, because purchasers will select the best picture quality, Samsung executives said.The RDZ displays are also 2D compatible, and are said not to meddle with image-quality in 2D mode. RealD is focused on delivering a premium 3D experience on screens of whatever size, from motion picture theaters to consumer electronics, and we look forward to working with Samsung LCD to develop this new 3D display technology, Bob Mayson, RealD electronics president, recounted in a press release asserting the joint development plan. Patterned-retarder-based 3D televisions today reduce 3D video resolution by half for compatibility with passive 3D eyewear. Conversely, RDZ 3D displays deliver a full-resolution high-definition 3D experience through an active-switching LCD panel that can be viewed with the same eyewear employed in RealD-equipped theatres and do not compromise 2D image quality.
The active/passive concept is further said to pare down both the price and girth of active-shutter glasses, getting shot of the necessity for battery replacement or recharging, while avoiding the issues associated with synching glasses to the display emitter, so spectators can sit anywhere in the room without fear of losing the signal. Samsung asserted it is presently working on RDZ-compatible panels for forthcoming 3D HDTVs. Talking on a visible display products panel in the show, Bong-Ku Kang, Samsung Electronics product selling group senior VP, said competing passive 3D approaches couldn’t survive forever due to technical restrictions that scale back the viewing angle, introduce crosstalk interference with black and white, and reduce image lightness. He added that this year TV makers are moving 3D features deeper into their lines, manufacturing lower costs, which should increase demand and penetration of 3D equipment in the market.
Both LG and Toshiba, which is also introducing a passive 3D line this year, said the passive 3D approach enables longer viewing times without eye strain, and a lower total cost of ownership. Toshiba continues to also offer 3D models based primarily on active- shutter glasses, and is calling its new passive models Natural 3D and its active-shutter models Dynamic 3D. Toshiba also showed glasses-free 3D LCD displays in the 55-inch and 63-inch screen sizes, and is trying to establish whether or not to market them here. Similarly, Sony showed 3 glasses-free 3D TVs in three screen sizes as concepts of the future.
