LG 3d TVs
LG have shown their commitment to producing the latest in viewing technology, launching their first passive viewing TV in 2010 and pushing this as one of their main attractions. Passive refers to the glasses used to give the 3d viewing experience. As opposed to the active shutter glasses the passive ones are far cheaper and do not require all the electronics which are inside the active glasses – just like the glasses handed out in the cinema. However, it has been noted that the use of these passive glasses does reduce the overall picture quality, so really its a trade off, but don’t worry if this isn’t your cup of tea, as LG has a range of active shutter 3d TVs also.
Most recently technology has been advancing and it appears that passive glasses may not lead to a reduction in picture quality, something which could help to propel the 3d TV into the mainstream public consumer market.
LG has also brought out a prototype autostereoscopic 3d TV, meaning that the 3d experience does not require the viewer to put on glasses. This technology works to a fair extent, however, only when viewing head on from a distance of around 12 – 16 feet, at other angles blurring will occur. The technology is there but will take some more time to become fully functional.
