A
lot has been said about OLED technology in Television, but what exactly is OLED
– or Organic Light-Emitting Diode – is a type of display technology that makes
it possible to create even slimmer TV sets than LCD or plasma, while at the
same time making them more efficient and eco-friendly too.
With
the recent digital migration in Kenya, OLED television is set to awaken a new
experience for viewers. In addition to the lighter and slimmer sets that come
with this new technology, the most important aspect of OLED technology is the
picture quality and the colour depth. OLED pixels emit light directly, viewing
angles are much wider, plus colour and contrast stay the same from as far as 90
degrees off Centre. Basically, in a typical Kenyan living room, every family
member should be able to enjoy the same television viewing experience.
And
because each pixel can be turned off individually, OLED TV’s can do their best
to deliver an absolute black and infinite contrast ratio – the Holy Grail for
picture purists everywhere. OLED pictures should also be brighter and can
achieve response times of less than 0.01ms, which practically eliminates motion
blur.
From
a technical perspective, here’s how the technology works: an organic,
carbon-based film is placed between two conductors and an electrical current is
passed through, which causes it to emit light. This differs from LCD TVs, which
require a backlight to create their brightness. OLED pixels are self-emissive
and generate their own light.
There
are two types of OLED technology, Passive-Matrix (PMOLED) and Active-Matrix
(AMOLED). Active-Matrix requires electronics to switch each pixel on or off
individually, which is better for displaying motion and therefore the type used
for OLED TVs.
So
far, only two manufacturers are thriving in the post-CRT Design era, LG and
Samsung have already launched OLED TVs globally. But there is a crucial
difference between the OLED technologies used by LG and Samsung, relating to
the sub-pixel structure. In its OLED TVs, Samsung uses a traditional red, green
and blue (RGB) pixel structure with no colour filters, just like you’d find on
a plasma.
By
comparison, LG OLED TVs use WRGB 4-colour pixel technology, which adds a fourth
white sub-pixel. White light is shone through a colour filter to create the
red, green and blue sub-pixels. LG says these cutting-edge results in a
brighter picture.
All
said and done, all you need is a future-proof bendable OLED screen from LG.
