What does the future of visualization technology hold for us?
The first time we tested the visualization technology was in
the 19th century, when the cathode ray tube made its debut. Now, approximately
150 years later, we have things like touch screens, LCD screens, OLED, Ultra HD
and many others that make one thing clear: the evolution of screen technology
continues.
From this evolution, the new visualization technologies of
today give us better viewing angles and improved color spectra with blacker
blacks and brighter colors. In addition, the technology of visualization is
literally everywhere and has permeated our daily life; It's in our televisions,
computers, phones, tablets, refrigerators and a lot of other devices.
As for the future, there continue to be developments in
screen technology that indicate that the screens of tomorrow will look and
function like the futuristic screens we have seen in countless movies and
science fiction programs.
Let us begin.
2018 screen technologies and next generation screen technologies
Living at the end of the decade of 2010 means that much of
the technology we use every day seemed like science fiction in the early 2000s.
For example, touch screens and screens that offer images so clear they seem
even more real than the real life.
We also have a great variation in terms of screens; if you
value the display relation on other characteristics, there is a screen for you;
If you prefer color quality over other features, there is a screen for you.
The point is that the world of the screen has evolved
rapidly since its inception, and now we have so many options ranging from LCD
and OLED to electronic ink:
LCD (liquid crystal display)
LCD screens, unlike OLED screens that produce their own
light, use a backlight or a reflector to illuminate the pixels: liquid crystals
do not emit light. As such, while OLEDs are called emissive because they
produce their own light, LCDs are called transmissive for the opposite reason.
Note that some LCD screens use LED as a light source and,
therefore, are called LEDs. In addition, some LED LCD screens use "edge
lighting" instead of a backlight, in which the LEDs are located on the
side.
And because they do not use phosphors, LCD screens are not
plagued with burns when an image is left on the screen for a long time.
Instead, they may suffer the persistence of the image, but this is only
temporary.
As for where you will find them, LCDs are commonly found in
televisions and consumer portable devices such as smart phones, smart watches
and digital cameras.
OLED (organic light emitting diode)
As we have just covered, OLEDs produce their own light and
do not require backlighting, which allows them to be very thin.
What we did not cover was that this is done with organic
materials that shine when they are introduced into an electric current, and
that individual pixel can be deactivated for darker blacks.
In addition, since each individual pixel can act as an OLED,
they come with a wide variety of colors and a high contrast that produces high
resolution images, which makes them the favorites of TVs.
Curved screens
Curved screens are gaining popularity because they enhance
immersion and add depth to whatever you're watching. For example, the curve
makes the images seem to wrap, functions that make you feel as if you are
seeing a larger image than a conventional screen.
Flexible screens
Flexible screens are similar to curved screens in the sense
that they are not exactly flat, but that's it. While curved screens are just
that, curved and flexible screens use malleable materials that can be reshaped
in different configurations.
Due to their malleability, these screens are also quite
shockproof, which makes them an attractive option for future use in
technologies such as smartphones and portable devices.
E-Ink (electronic ink)
Widely used for readers like the Amazon Kindle, electronic
ink technology was created to replicate the appearance of ink on paper through a
process called electrophoresis, which is a relatively new technology that uses
a transparent fluid combined with black pigments and White pigments with
positive charge to create the real ink screen readers around the world love.
Why do they love it? Because it produces high resolutions
with readability to sunlight and a very low energy consumption due to the fact
that readers that use electronic ink only consume energy.
