Expat Show Tv

Archive for the ‘Tv 3d’ Category

WATCHING 3D movies has always been exciting. But how many of us have the gadgets to get a 3D experience at home? We wait for things like ‘Avatar’ to happen, grab a pair of black goggles and catch the best seats in the theatre to get that mind-blowing experience. But not anymore.

If Sony insiders are to be believed, the company is soon launching Plasma and LCD television sets which are capable of creating the same 3D experience in your very own living rooam.

Sony has come up with a first of its kind, 3-D-ready audio receiver.

The gadget called the STR-DN1010 would be available in the US markets by June 2010 and will cost about $500.

Add to it the video counterpart, HDMI 1.4 which has the capability to its feature 3D effect, allowing a full HD 3-D signal to be passed from a 3-D Blu-ray player. The receiver takes the signal and passes it into a 3-D-capable HDTV.

Sony Corp hopes 3D models will make up 10 percent of more than 25 million LCD TVs it aims to sell in the next fiscal year. The maker of the PlayStation 3 game console also plans to release 3D game software in time for its 3D TV launch in June.

Samsung Electronics Co Ltd, the industry leader for flat-screen TVs, will begin U.S. sales of 46- and 55-inch 3D TVs this month, with other models coming over the next several months.

Only the new version of HDMI, version 1.4, is capable of passing a full HD 3-D signal from a video source to a display.

Sony has previously announced its first 3-D-capable Blu-ray players, shipping now. The BDP-S470 ($200) and BDP-S570 ($250) will be able to transmit 3-D Blu-ray movies after a software download available this summer.

What is a LED TV

A led TV is an LCD TV that uses LEDs to illuminate the display. There are two ways to do this: either by placing LEDs across the entire back of the display, or by placing LEDs just around the perimeter, which is called an “edge lit” display. Both techniques use less power than plasma TVs and LCD TVs lit with fluorescent tubes.

History of LED TV

LED technology was first used as status and indicator lamps. Over the past six years though, it has been developed to meet general lighting application demands. Samsung is among the first to incorporate light-emitting diodes (LED) into television technology, it is called the LED TV which is now taking the technological world by storm. Samsung uses a term LED TV (light emitting diode television) for describing LCD (liquid crystal display) TVs which utilizes LED Backlighting. LED TV is a controversial term effectively used for the advertisements between Samsung and its competitors. But the complaint of the competitors is, LED TV produces a display of 100% LEDs and which is not compromised in this. LEDs in their current form are much too large to be individual pixels on a conventional television. In order to capture some of the hype around O-LED TVs, Samsung has chosen to brand their LED-lit range of LCD TVs but still except for the Sony XEL-1 they are not commercially available. LED-backlit LCD TVs do differ from conventional LCD TVs in some important areas: 1. LED televisions can produce bright image and deep blacks (doesn’t work for Edge-LED). 2. They can be extremely slim with Edge-LED lighting. 3. LED TV offers lower power consumption. 4. Especially when RGB-LED backlighting is used, LED TV also offers a wider colour gamut.

LED in Television Application

LED technology captures the natural colours of real life with the production of darker blacks, crisp whites, and strong contrast between dark and vivid colours. Samsung also enhanced its LED-powered products with Auto Motion Plus frame interpolation, which effectively reduces image judder and motion blur.

Also called stereoscopic semi rimless glasses, 3D (three dimensional) glasses are capable of recording three-dimensional visual information or creating the illusion of depth in an image. First invented by Charles Wheatstone in 1838, 3D glasses create the illusion of depth in photographs and movies by presenting a slightly different image to each eye. In other way, 3D glasses provide the eyes of the viewer with two different images that represent two perspectives of the same object so that the brain will receive a depth perception. This is the basic principle of 3D glasses.

Among the various 3D rimless glasses styles, polarized 3D glasses are special. They create the illusion of three-dimensional images by restricting the light received by the eyes. Using orthogonal polarizing filters, polarized 3D glasses project two images onto the same screen in order to show a stereoscopic vision. Through these filters, light that is similarly polarized can pass so that each eye receives only its separately polarized image, and then a three-dimension effect appears.

Currently, you can easily find 3D glasses online. There are some professional 3D glasses online stores, such as 3dglassesonline.com, 3dglasses.net, 3dglasses.com and berezin.com. Depending on your special event or purpose, a wide variety of 3D glasses applications and styles are available, such as Anaglyph plastic reading glasses, Pulfrich 3D glasses, hand held 3D glasses, Proview professional 3D glasses etc… You can also get 3D glasses in clip-on.

3D glasses are the indispensable device when watching 3D TVs, 3D movies and 3D videos.
