The Evolution of TV Display Technology: OLED Bursts onto the Scene
There
have been four types of display technology in the history of
television: Cathode ray tube (CRT), plasma, LCD, and OLED. Each time
that the tech level increased, a massive increase in picture quality
standards followed. Just as there was a huge gap in picture quality
between CRT TV and plasma TVs, there’s an even larger gap between LCD
and OLED TVs. What makes this possible is the fact that OLED needs no
backlight. Each individual pixel can emit light on its own. This enables
OLED to create the perfect shades of black, and an infinite contrast
ratio, both of which would be impossible with a backlight. For these
reasons, the shift to OLED TV will be just as revolutionary for display
technology as the advent of the smartphone was for the mobile phone
industry.
The
difference of picture quality between LCD and OLED is evident in the
picture above. The image on the left is what you would see on an LCD TV.
The backlight panels bleed the image, creating light on pixels where
there should be none. But OLED renders each pixel as bright or as dark
as it should be, creating a strikingly crisp, smooth and clean picture
that is both pleasantly rich, yet achieves a convincing realism with
subtlety. You may say that the bad picture quality never took away your
enjoyment of the film before, but after watching it on OLED you’ll never
want to return to anything except OLED. Black level not only delivers
black we enjoy in a dark movies, but does color vibrancy its justice
What We Can Expect from LG’s New OLED Display Technology
Think
of an image of a night sky. How dark are the black parts of that black
sky? If you are a city-dweller, it’s quite possible you don’t know how
dark it should be. That’s because the night sky is polluted by
artificial light sources. It is only when we travel away from
civilization, out into the wilderness that we can truly appreciate the
majesty of the night sky. With no light pollution, the blackness of
space makes many more objects in the night sky visible.
The
graphics below are intended to show the effects of light pollution. On
the left side, we can easily see how city lights can make it harder to
see the stars in the night sky. On the right, we can see that LG OLED TV
is most similar to a night sky free of light pollution. An image of
bright dots on a black background looks far more crisp and clear on an
LG OLED TV, while it is rendered blurry and less visible on an LCD TV.
LG Electronics – the world’s leading OLED TV provider – recently released a short video clip (Link)
titled ‘Colorful Sensation in Black’. The clip depicts a number of men
running and jumping while wearing black clothing, helping to emphasize
the importance of effective black rendering in determining the accuracy
of today’s advanced displays. In fact, a display’s precision in
depicting pure black images is one of the major elements that home
entertainment experts use when appraising TVs.

See Your Favorite Films Like You’ve Never Seen Them Before with OLED, the Next Step in the Evolution of TV Technology
Over
the past few years, 4K (ultra HD, 3840 x 2160 pixels) TVs have become
more and more common in the average home. As the new technology becomes
more and more affordable, it too becomes widespread. People have thus
become more used to higher quality, clear sound, and a better overall
viewing experience. The leap forward in TV technology makes older
technology (such as CRT television) seem archaic. But it is through this
archaic technology that we have seen many of the films and movies that
we love. But what would the classic Tim Burton Batman films, or the
original Star Wars trilogy look like in 4K? What if you’ve been seeing
both of these series in sub-par quality all your life?
How would
one describe the visuals in both Batman and Star Wars? In a word, dark.
But whether it is Batman’s flowing black cape, or X-Wings flying toward
the Death Star from their base on Yavin IV, the color black is
extremely essential to both films. In fact, experts judge a TV’s ability
to portray black as one of the major elements that make up their
ratings of TV technology. Along with contrast ratio, black level is one
of the two most important factors in picture quality in today’s TV
technology market. One technology has been developed that doesn’t just
render black well, it does it to perfection.
