3DTVs that do not require 3D glasses are on most peopleâ€™s lips these days. At IFA 2010 Philips has showcased a prototype of a 3D display that does not require 3D glasses. Here are our impressions.<br /><p align=center><i>FlatpanelsHD will be in Berlin to cover the worldâ€™s largest consumer electronics fair IFA 2010.

The manufacturers also exhibit future technology and in collaboration with Dimenco Philips has showcased a 3DTV prototype that does not require glasses.<br /> <br /><p align=center><a id="thumb" href="pictures/philips3dnoglasses-2l.jpg" class="highslide" rel="highslide"><img class="imgresponsive" src="pictures/philips3dnoglasses-2.jpg"alt="Philips 3D without glasses" title="Click to enlarge" /></a><br><i>Philips 3D without glasses</i></p><br />The technology is based on the so-called lenticular lens that we know from cornflakes boxes. The TV emits light in two divergent angles, in order to let the human eyes perceive two different images and thereby create an illusion of depth.<br /><br />The disadvantage is that you have to stand in the"sweet spotâ€ť to get a 3D effect. Philips says that the TV has 15 3D sweet spots but all other places just give us a blurry image. The TV is 56 inches large, based on LCD and has a resolution of 4Kx2K (four times higher than Full HD).<br /><br /><h3>Not really convincing</h3>So how did it work? Well, not very convincing. The picture is not in focus and picture detailing is not very good. You also have to stand in the sweet spot to see anything that resembles 3D. <br /><br />The 3D depth and 3D illusion is far from that you see on the 3DTV that require glasses today. Actually, I have to say that most of the clips had no or very little 3D to it. Other clips were better but not impressive.<br /><br /><p align=center><a id="thumb" href="pictures/philips3dnoglasses-1l.jpg" class="highslide" rel="highslide"><img class="imgresponsive" src="pictures/philips3dnoglasses-1.jpg" alt="Philips 3D – not in sweet sport" title="Click to enlarge" /></a><br><i>Philips 3D – not standing in sweet spot here</i></p><br />Dimenco - who developed this 3D prototype for Philips – says that theyâ€™ll have a working consumer model in the market by 2013.<br /><br />Until then I have to say that 3D without glasses is just not good enough. We hope to see it someday but if you expect this within a few years you should probably get your hopes down. The quality is far from convincing. The prototype has also been exhibited before an I donâ€™t see an improvement over previous yearâ€™s models.<br /><br />Philips has 3DTV in the market that require 3D glasses such as the <a href=http://www.flatpanelshd.com/news.php?subaction=showfull&id=1279200177 target=_blank><b>8605H series</b></a>.
