Well, soon it will be. Although, Plasma and LCD panels look the same,
the technology behind them is different. Plasma is a phosphor-based
technology where tiny gas plasma cells are charged by electrical voltage
to create a picture. LCD or liquid crystal display screens, on the
other hand, are more of a transmissive device and are made up of liquid
crystal sandwiched between two glass plates. By changing the amount of
electrical charges that are passed through the crystals, an image is
produced.
One of the original differences really was screen sizes. Plasma
TV boasts of screen sizes ranging from 32 inches to 60 inches. And they
can even create larger than that. Meanwhile, LCD TV displays seem to be
within the 13 inch to 46 inch range. But due to recent technologies,
manufacturing bigger LCD screens have become more affordable. Soon this
difference will no longer exist, but for now, let’s say that Plasma can
come in bigger sizes than LCDs.
Again, another difference that is slowly being changed is the viewing
angles. Plasma displays used to have better viewing angle, while LCD
screens will often show some color shift when viewed too far of an
angle. However, with regards to display, Plasma has better contrast
because it shows deeper blacks and has brighter colors since LCD usually
have some light leakages which affects the color saturation of the
display.
The costs of owning an LCD screen has gone down to the level or very
close to the market price of Plasma display units. LCD screens were used
to be more expensive than Plasma, but today are becoming very
competitive in price, size and resolution.
I mentioned resolution, although LCD used to brag before that it has
more resolution than Plasma displays of the same size. However, high end
Plasma units can practically display the same number of pixels on a
screen than LCDs. Plus, the quality of the image in a Plasma seems
better than in an LCD’s.
LCD screens are thinner and lighter than similar sized Plasmas. The
LCDs have an edge in that aspect. Also, LCDs are generally more energy
efficient, since they are able to consume less power than Plasma
screens. On the average, LCDs use almost half of the power from Plasma
TVs.
The issue of Plasma screen’s total lifespan is also worth mentioning.
Today, Plasma models will be able to lose half of its brightness
between 30,000 and 60,000 hours of viewing. But LCDs have a guaranteed
60,000 hours of viewing before noticeable lose of brightness is
observed.
Another problem with Plasma TVs are the so-called burn-in image which
happens when the screen stays too long on a static image. This problem
is non-existent with LCDs. Moreover, Plasma screens are affected when
brought in higher altitudes. The reason is the gas inside the unit is
being stressed by atmospheric pressure affecting its performance. LCDs
do not have this problem.
So, which one will you choose? Personally, I will choose an LCD
screen over the Plasma simply because of the less power consumption and
the fact that I won’t be using big screens anyways. But for huge
screens, Plasma seems to be a better choice.
