The main advantage of OLEDs
is that they make the displays
much thinner to a range of
0.2mm-0.3mm (or 1/8000
inches). LCDs are 10 times
thicker than this.
OLEDs are also much
brighter and more flexible.
Since they are brighter, they
don’t need a backlight.
Thus, the power consumption
is less in OLEDs. Therefore,
using them in mobile devices
where batteries are used,
will give more battery life.
When fast moving pictures are
displayed, OLEDs respond up
to 200 times faster.
They can produce more realistic
colours through a much
bigger viewing angle, unlike in
LCDs, where colours are darker
and tend to disappear when
observed from various angles.
OLEDs are already used in
many types of companies
such as Samsung, Google,
Apple, Sony, PANASONIC,
Lenovo, HP, Fujifilm and
Toshiba to produce mobile
phones, tablets, computer
monitors, TVs, cameras,
laptops,
car radios,
lamps,
etc.
But
OLEDs
also have
drawbacks.
One of
the major
drawbacks
is
Experts are working on figuring
out solutions for these
problems of OLEDs. With the
technology they have, solutions
will be found in the near
future and it is just a matter of
time for OLEDs to start a new
era in electronic displays.
that they do not exist for a long time. The degradation of
the organic molecules tends to wear out around four times
faster than conventional LCD or LED display. Other than
that, the organic molecules in OLEDs are very sensitive to
water. That can be a major problem specially in manufacturing
products like mobile phones.
