Sony Bravia 3D LED TV
What sets Sony Bravia 3D and LED TV sets apart from the crowd. Well certainly they are known to be some of the most technically advanced TV sets around, but what have Sony got to say for themelves on this issue? Our friends in Vancouver had a chat with a Sony Canada representative to see what they had to say – this is what they found out!
Well, first of all it’s in full high definition, 1080p (the most detailed) high def these days and it’s also like stereo for your eyes, with one image for each eye to give the full 3D experience.
This is achieved by using what Sony call the “projector method” where they produce two distinct images, one for each eye. They then shift the frames so that every sixteenth of a second a different image is presented to each eye – left and right, alternating images. That’s the basis of how Sony create 3D. In effect it is an illusion that tricks your brain via your eyes.
But what about that age old chestnut of crosstalk – the blurring of the 3D image? Certainly this can and does happen on many 3D TV sets. Crosstalk is in actual fact the images for the left and right eyes getting a little bit “mixed up”. The timing of the image delivery goes awry and the left eye sees a little of the right eye image and vice versa. This causes a ghost or blur (mainly to the periphery of vision) that has come to be known as crosstalk.
Sony say that with their latest Bravia 240Hz screen panels they are now able to totally isolate each image for both eyes resulting in a crisp, sharp image when viewing even the most hectic of 3D scenes. Certainly in viewing the latest Somy Bravia 3D sets our Canadian friends did feel that crosstalk was “donw to a minimum or even dispelled all together”. This is a definite move forward for active shutter 3D technology.
Another issue in designing 3D TV (particularly active 3D) is how comfortable are the glasses? Personally, I have a vested interest here being a wearer of normal glasses.
Firstly Sony say you simply have to cut out all the ambient light from a room to get true 3D. Early 3D certainly suffered from flickering particularly in the area of vision outside of the actual screen. This is a particulart problem with European 50Hz 3D sets.
Sony say their Bravia 3D system is “flicker free”.
They can do this due to an advanced “screen blocking” system that amazingly blocks part of the screen image in order to give you a clearer, brighter version of the “overall” image that you do see. In essence there is a split second where you cannot see anything. But this happens so quickly you don’t notice it! Again this is the images (or lack thereof) causing the brain to create an illusion by blocking certain images so you see other images which go together to make the whole. This all happens at an incredibly fast speed in the active shutter glasses while you sit back and enjoy crystal clear 3D images! It’s really quite interesting how it works, but a little on the boring side to explain fine in detail – needless to say it works!
My only worry is that all this tech can go wrong in which case you have an expensive pair of 3D glasses to replace! Not so with the “Cinema” 3D glasses as they only cost a few bucks. However, purists would argue “Cinema” 3D has limitations and that active shutter is the only way to get “true” 3D on a TV. That however is an argument for another day!
Obviously the images produced are the main reason for buying a 3D TV, however, the physical design of the 3D glasses have a big impact on how much you enjoy your viewing experience.
Most people are going to have their 3D sets in the living room where there will inevitably be many different sources of light. Sony 3D glasses completely block out all extraneous light sources. Outside light would have a major impact on image quality by reflecting off the back of the lenses. This would cause uneven light on the viewed image and a complete loss of picture quality.
So, the glasses wrap around the eye to block out all external light sources. They also have to be ultimately adjutsable – in order to fit any family member. The arms of the glasses are flexible and can be moved to grip the side of the head as well as turned in to fit snugly. The nose piece is also fully adjustable so that you can set it to fit each individual viewer. Finally, the earpieces are also flexible so you can bend them to provide that custom fit and grip. Finally, (and most importantly for people who already wear glasses) they are large enough to fit over any pair of normal glasses.
So, these active shutter glasses have tinted lenses, doesn’t that mean the images will be darker and the brightness lost when viewing in 3D?
Not so, say Sony!
LED Boost technology actually bossts the power to the LED lights when watching in 3D. In this way, the brightness of the image you see through the glasses is the same as when watching normal 2D TV without the glasses. This ensures you see a beautiful, bright picture no matter where your set is – you won’t need to darken the room at all due to LED Boost.
The image processing is vital to Sony TV performance. With many years experience, Sony manufacture everything in the picture making process…from the cameras that film your movie or sport, to the actaul image engines in the TV sets through to the screens you finally view the picture on in your home. This means that Sony have quality control at every stage of the process.
When coupled with the Bravia Engine and Sony’s live color technology comes together to produce colors that are acurate and correct. Just as you remember seeing them in the cinema or indeed the live action – that’s how you’ll see them on your Bravia.
There is also an advanced contrast enhancer that works with your backlight to make sure that the contrast is optimized and looks as good as it can possibly look.
And, the last piece of the jig-saw is Sony’s image blur reduction which takes images where the source might actually be blurred and sharpens it up to give you a completely natural look on the television image. This is particularly effective when watching sport or action movies.
In short Sony say their aim is to make the best possible 3D viewing experience and our Canadian reviews agree, the images on today’s latest Sony Bravia 3D LED TV sets are outstanding. The only downside is the price compared to, say, an LG Cinema TV or a Vizio. Yes, active shutter does give a better, clearer, sharper 3D image and Sony offer one of the best crosstalk solutions…but, is it worth the extra $$$. Only you can decide that!
