ULTRA -THIN TELEVISION

ULTRA -THIN TV
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. Tommorow it could be a folded television
set.Many of us are still agonizing over whether our next television
set should be a Plasma or a Liquid Crystal (LCD) screen, assuming
we can afford to buy either.
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 - defination display technology.
It is called Organic Light Emmiting 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 roll-up a portable TV and carry it in a pocket
or purse for viewing while ''on the go''.Recently, Sony announced that
it will be putting on sale, sometime in december this year.
The XEL -l has a 11 inch (28cm) screen;it is just 3mm thick and
weighs less than 2kg. 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, 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.
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 meter, much as textiles are
manufactured today.
