LCD Screens
Black Box Explains
Plasma vs. LCD screens.
When deciding whether to use plasma or (LCD) displays for your
applications, you need to consider many factors. Both provide brilliant
colour, sharp text contrast, and crystal-clear images, but the way in
which plasma and LCD screens process and display incoming
video/computer signals is markedly different.
Compare and contrast.
Both plasmas and LCDs provide stark enough contrasts to make
displays sharp and pleasing, but when it comes to contrast output,
plasma technology outperforms LCD. Some plasma displays have a
15000:1 contrast ratio, which is the measure of the blackest black
compared to the whitest white. LCDs use electric charges to untwist
liquid crystals, thereby blocking light and emitting darker pixels.
Despite this process, in general LCD displays don’t display as high a
contrast ratio as Plasma screens.
Clarity that’s light waves ahead.
Pixels contain enough information to produce every colour in the
spectrum. Because plasmas use each and every pixel on their screens,
colour information is reproduced more accurately. Plasma screens
display moving images with remarkable clarity, though burn-in can be
an issue. For displays with lots of light and dark imagery, plasma
panels provide excellent performance with their high-contrast levels,
colour saturation, and overall brightness.
LCD displays, on the other hand, manipulate light waves and
reproduce colours by subtracting colours from white light. Though this
makes it more difficult to maintain colour accuracy and vibrancy
compared to plasma screens, LCDs have an advantage with their
higher-than-average number of pixels per square inch. These
additional pixels make LCD technology better at displaying static
images from computers or VGA sources in full-colour detail. Plus,
there’s no flicker and very little screen burn-in. Applications with large
amounts of data—such as those found on spreadsheets—display
particularly well on LCD monitors.
Brilliant displays that go on and on.
With LCD screens, there are essentially no parts to wear out. LCD
screens last as long as their backlights do, with displays lasting, on
average, 50,000–75,000 hours. That’s why LCD screens are especially
good for long-term applications, such as digital signage or displays
that require around-the-clock use.
Plasma screens, however, use a combination of electric currents and
noble gases (argon, neon, and xenon) to produce a glow, which in
turn yields brilliant colour. The half-life of these gases, however, is only
around 25,000 hours. The glow they produce grows dimmer over time.
NEC MULTEOS Screens
