OLED is the future of
TV sets, At present it is LCD's reign,
though not for long. But in present Only four companies, Samsung and LG
have manufactured OLED TV sets. In 2012, Sony and Panasonic had announced
that they will jointly manufacture these.
Science behind it:
OLED screen previously were used in cellphone and digital camera, but their manufacturing cost kept them from being produced as big TV screens .
Why it is Better? (Here LG is used as example)
An LCD TV needs a backlight, but an OLED’s pixels emit their own light. So turning them off makes them go completely black, with none of the afterglow you’d get from phosphor-based technologies—like cathode ray tubes or plasma displays or even from an LED-backlit LCD, which can dim only regions of the screen, not individual pixels. Being able to create a really black, greatly improves picture quality
LG has announced that its first 55-inch OLED TV is just 4
millimeters thick and weigh 7.5 kilograms. A comparable 55-inch LCD TV from LG
is nearly 4 centimeters thick and weighs about 22 kg.
Prices:
LG uses a
technology known as WOLED (White OLED with colour filters), for which the
average price of one display comes to $3,600 (around £2,250). Whereas Samsung
uses a different technology, called RGB (Red, Green and Blue) OLED, for which
the average cost of manufacturing one unit becomes $7,300 (approximately
£4,550).
Prices are insanely high, it could be better if prices made low, What do you say ?
Neither technology is especially cheap, yet the difference in
production cost is evident, Samsung’s curved OLED TV is available for just €7,999 in Germany,
compared to €8,999 for LG’s.
