Do you wanna know abt "POCKET TELEVISION"?...then go through this article:

If your daily trip to work involves commuting for long spells, by bus or train, you might, today, be carrying a folded newspaper to while away the tedium. Tomorrow it could well be a folded television set.
Still agonising ....
Many of us are still agonising over whether our next television set should be a Plasma or a Liquid Crystal (LCD) screen, assuming we can afford to buy either. Yet these competing technologies are already being challenged by a brash, ultra slim and amazingly sharp newcomer, that might well push us into the next era of high-definition display technology. It’s called Organic Light Emitting Diode or OLED — and among other characteristics, it can be rolled out as a flexible, rather than a rigid sheet.Which means, that some time in the coming decade, we can expect to fold or roll up a portable TV and carry it in a pocket or a purse, for viewing while ‘on the go.’
Right now, OLED TV monitors are thin — but not that thin. Recently, Sony announced that it will be putting on sale, sometime in December this year — and initially only in Japan — the world’s first OLED-based TV set. The XEL-1 has a 11 inch (28 cm) screen; it is just 3 mm thick and weighs less than 2 kg. Its high definition (1920 by 1080 pixel) screen has an amazing and hitherto unachievable ratio of 1,000,000:1. It will cost 200,000 yen, that is, around Rs. 67,000. That might sound like a lot of money for a small hand-held TV panel but the situation is poised to change dramatically, price and availability-wise. Toshiba has already announced that it will forsake these small screens and come out with its own OLED offering — a 30 inch TV model — by 2009.
Less power overhead
To put it in simple terms, since an OLED emits light, it does not, unlike an LCD panel, require additional back lighting to create a bright image. That, straight way reduces the power overhead and allows manufacturers to reduce the effective thickness of the monitor screen.
An OLED is created by placing a series of carbon-based organic thin films, sandwiched between two conductors.
Fabrication innovations :
When a current is passed, bright light is emitted by the organic film layers. Most of the early patents in OLEDs were obtained by Kodak in the early 1980s, while fabrication innovations have been made by many other companies. In 1999 Kodak and Sanyo jointly developed the first full colour 2.4 inch OLED display panel. Indeed, many of us might be using OLED panels today, without realising it. They are already to be found in many small screen devices like high-end, graphic mobile phones, portable video players and the like.
Consumers’ hunger :
Worldwide, consumers’ hunger for better, sharper, brighter television and video screens, fuelled by the imminent availability of high definition media like Bluray and HD-DVD, may be just the stimulus that will kick start the OLED business and make it a mass consumer contender. In many countries, governments are also doing their bit by mandating cut off dates for the analogue TV transmission as we know it today, after which all TV will be high-definition and digital.
Compelling attraction :
Even without these market-driven factors, OLED technology has a compelling attraction for the display industry: It can be manufactured in the form of flexible or near-flexible sheets — holding out the hope that some time in the future, TV makers will roll out television screens by the metre, much as textiles are manufactured today.
Reference models :
Sharp, Epson, Samsung are all known to have perfected their own OLED technologies for large screens like TVs and PC monitors — indeed most of them showcased reference models earlier this year at the Consumer Electronics Show in Las Vegas, that went up to 40 inch diagonal.
One of key advantages of the Sony 11 inch OLED TV, after the extreme fidelity of the picture, is its frugal power requirement — less than 45 watts.
The reason lies in one of the core design features that distinguishes OLED panels: its property of electroluminescence, when excited with an electric current.
