The Decade of 3D Technology


2010 continues to introduce an increasing array of 3D devices as we all know it. The technology constantly enhances as companies rush to deliver better and affordable products. The likes of the 3D Nintendo DS made most of the headlines because of their no-glasses-required strategy – which most people prefer than wearing – well, stupid glasses. You do remember the red and blue glasses that come in cereal boxes, right? Those things are history. Here, you’ll know how we get to enjoy the much-hyped 3D technologies of the decade.The BasicsWhen we’re watching a 3D movie at the cinema (and wearing the glasses of course), both of our eyes perceive different variations of images which our brains process to produce depth on what we see. This is the basic principle of 3D. We use different technologies on the glasses too but all of which supports the same principle. Polarized and Active Shutter GlassesPolarized glasses are usually the cheap-looking ones in black we wear in the cinema. They essential filter different light to each lens from the two or one projectors. This 3D technology is arguably expensive. Special silver screens are required to make it work and sometimes it affects the color accuracy of the images. The ones we use in 3D-enabled TVs today are active shutter glasses. The two lenses open and close rapidly in sync with a particular frame on the screen. Our eyes see different images then the brain does the hard work of combining them into one 3D image. Most of these cost more than $100 bucks – really expensive but if you want 3D in the comfort of your home, you have to settle buying one at the end of the day. 3D Devices TodayCurrently, there is no standard for any devices that supports 3D. It’s up to you what 3D technology you’ll buy once you decide to get one. Sony released LCD 3D-enabled TVs this year as well as plasma 3DTV from Panasonic. Both of which have their own strength in their displays. Recently, Toshiba announced a no-glasses TV; we’ll have to wait if it really is better than today’s 3D. 3D technology has really evolved so much since its primitive days. From cinemas and now to our very own televisions, so what’s next? – a 3D enabled tablet computer maybe(hello Apple!)? 3D cellphones?  So for now, we have to plod with those geeky glasses.Source: Free Articles from
