Ever since the introduction of the first flat panel TV in the market,
TV sets continually become thinner, brighter and clearer. It’s only
natural that television companies set their sights on OLED technology. OLED TV
is the next big thing in television today. Here’s a breakdown of how
OLED TV could change the way we watch in the comfort of our homes for
What is an OLED TV?
An OLED TV uses a new display technology called OLED or organic light emitting diode.
Unlike LCD/LED and plasma televisions, OLED TV is thinner, lighter and
more energy efficient. It works like this: when electricity passes
through an OLED material, the material emits light, thus a whole panel
of OLEDs create an image through this process.
What is OLED technology?
is made from organic (or carbon-based) components that are placed
between two conductors. It emits light when electricity is applied. It
does not require a backlight thus it is more energy efficient. The two
most common OLED displays today are the PMOLED (Passive-Matrix OLED )
and the AMOLED (Active-Matrix OLED). PMOLED is cheaper and easier to
produce but is limited in size and resolution compared to AMOLED. While
AMOLED displays are more efficient and can be made larger, they are
also expensive and complicated to manufacture.
these types of OLED displays are now commonly used. PMOLED is used on
mp3 players and secondary displays on cell phones. Smartphones and
digital cameras commonly used AMOLED displays since these electronic
devices require higher resolutions in their display panels.
While OLED displays offer better viewing experience and aesthetic designs of devices, this technology still lags behind LCD and plasma
display in terms of panel lifetime and production scaling. Larger OLED
display panels are expensive and difficult to manufacture.
to these current limitations that manufacturers are facing, OLED
displays are more commonly used in phones, cameras and MP3 players.
Since OLED displays require less energy, they are ideal to use in
battery-operated electronic devices like smartphones, digital cameras,
A/V players and lamps.
The difference between LED and OLED TVs
what’s the difference? OLED TVs are just LED TVs with "organic”
materials in them, right? Well, no. LED TVs are actually LED backlit
only, essentially being an LCD TV with LED backlights. These backlights
may be placed at the edges of the panel or a full array placed behind a
screen. OLED TVs by contrast are electroluminescent, meaning they do not
need a backlight as each pixel is a light emitting diode in itself. The
elimination of backlighting offers a vast potential for future OLED TVS
that can be as thin as a paper and flexible too.
The pros and cons of OLED TVs
makes an OLED TV better? First, its cost will be cheaper eventually,
due to the fact that OLEDs can be printed on any suitable substrate,
theoretically making them cheaper to produce. They are also lightweight
and thinner than panel made from older LCD technology. Another advantage
is its wider viewing angles and improved brightness, so more people can
watch a show more clearly. Plus, better contrast and color reproduction
ensures that it creates a great image from any angle.
earth? Well OLED is greener since power efficiency is greatly improved
since an inactive OLED does not consume power or emit light and no
harmful metals are used in production.
Now we go to the bad parts of OLED.
now, an OLED display is very expensive to produce. Plus, its lifespan
is short especially for the blue diode which averages at 14,000 hours
compared to LED TVs which range around 25,000-40,000 hours. Since the
blue diode degrades faster than other diodes, it wrecks the color
balance of the TV. Power consumption for white backgrounds is also three
times as much as LCD does.
When will OLED TVs become mainstream
there are already available OLED TVs but still expensive for your
average consumer. However giant electronic companies such as Samsung, LG
and Sony are now preparing for mass production of OLED televisions. At
the recently held CES 2012, these companies gave us a glimpse of the
future of OLED TV. It was announced by Samsung that mass production of
Gen 5.5 OLED displays starts this year in its new factory.
electronics also unveiled its full HD OLED TV 55EM9600 at the same CES
2012. This TV carries all the current features of LG TV including smart
TV with streaming and social media and passive 3D capability. It is
expected to be released by July 2012 at a price average consumers will
find too steep. According to LG price-competitive OLED TV sets is
possible by 2016.
The offering of several TV
display technologies in the market can make a consumer’s head into a
tailspin, wondering whether to jump into the new technology that is
currently the talk of the town. So do we buy now or wait until later?
have to carefully weigh the pros and cons before making a decision. It
really depends on one’s preference. If you have the extra cash and like
to have the latest technology in town then buy it and for sure you
wouldn’t regret it as it’s the best a consumer can get.
is an issue for you, OLED is simply not the best bet, at least for the
time being. It’s best to wait it out until they are produced by more
manufacturers. If value for your money and quality is what you are
looking for, LED TV still rules.
