Nevermind 3D TV this or 3D Glasses TV that... This is What You Need to Know |
Today, a quality TV is about display quality, 3D ready TV, space to record saved programs and being able to get online. Skype is getting involved also so soon we will be able to make phone calls for free via our TVs. The market dominance of LED or light emitting diode TVs or backlit TVs, 3D TV and the ability to be on the internet with your TV are the most significant developments in the industry in 2010. 3D TV is a generic term for a display technology thats lets home viewers to experience TV programs, movies, games and other video content in a stereoscopic effect. It adds the illusion of a third dimension, depth. to current TV and HDTV display technology, which is typically limited to only height and width (2D). How can you get 3D from a 2D screen? A 3D TV or theatre screen showing 3D content displays two seperate images of the same scene simultainiously, one intended for the viewers right eye and one for the left eye. The two full-size images occupy the enture screen and appear intermixed with one another - objects in one image are often repeated or skewed slightly to the left (or right) of correspondingobjects in the other - when viewed with the aid of special 3D glasses. When viewers wear the glasses, they can percieve those two images as a single 3D image. How is the new 3D TV different from the older 3D? People are familiar with the old anaglyph method, where a pair of glasses with lenses tinted red and cyan is used to combine false colour images. The result seen by the viewer is discoloured and usually lower-resolution than the new method. The principal improvements afforded by the new 3D TV technologies are full colour and high resoultion - reportedly full 1080p HD resolution for both eyes in the Blu-ray 3D system, for example, and lower resolution 3D delivered by a TV network. The new 3D glasses being delivered by both Samsung and Panasonic work by very quickly bloching the left then the right eye in sequence (100 times per second). The glasses, in addition to the liquid-crystal lenses, contain electronics and rechargeable batteries (typically good for 80 or more hours), that sync to the TV via and infrared or Bluetooth signal. In Samsung's case, a button is located on the top right hand side of the glasses.
What is the difference between 3D in the cinema and at home? In the home, the image is generally much smaller, occupying a lower percentage of viewers' fields of vision. Among TV manufacturers, Panasonic is recomending a closer seating distance (of 3x the screen height awqay - about 3 meters from a 50 inch screen) for a better experience. I've heard 3D causes headaches. Is that true? Most viewers of 3D suffer no ill effects after a brief orentation period, but in others, 3D can cause disorientation or headaches after extended periods. Does everyone watching 3D TV need to wear 3D glasses? Yes. Every member of a familty sitting around the 3D TV must wear the glasses to see the 3D effect. If they don't, the image on the screen will appear doubled, distorted, and unwatchable. Yes. None of the TV manufacturers have a current model HDTV that can be upgraded to support the new 3D formats. We've heard that slow LCD response times, processing power, new phosphor requirements, and an inability to accept the necessary 100Hz input signal (not to be confused with 100Hz and higher display refresh rates) cited as reasons why existing sets are stuck in 2D. Do you need a Blu-ray player, set top box, game console, or AV reciever? With the noteable exception of the Sony PS3, the answer is for Blu-ray players is "yes". No Blu-ray player maker has said it will upgrade existing standalone players to work with Blu-ray 3D movies. Who has a 3D attachment advantage? sony has an advantage because it's PS3 will support 3D Blu-ray playback with full 1080p resolution to each eye via a simple software update, available later this year. On the other hand, other manufacturers, including Panasonic, have said HDMI 1.4 or simply HDMI as it is now called is required for full HD 3D, and as far as known the PS3 does not have HDMI 1.4. In addition, Sony Australia is advocating the use of a 3D dongle that looks like a Nintendo Wii sensor that sits on top of a TV. This will upscale a 2D TV to 3D. Right now we are skeptical of Sony's "full resolution" claim, although we are fairly certain the PS3 will support 3D for Blu-ray and for gaming. As for the Xbox 360 and the Wii, neither Microsoft nor Nintendo has outlined its planned for 3D gaming.
