WHAT
IS LCD TELEVISION?
Liquid-crystal display televisions (LCD TV) are television sets that
use LCD display technology to produce images. LCD televisions are thinner and
lighter than cathode ray tube (CRTs)
of similar display size, and are available in much larger sizes. When
manufacturing costs fell, this combination of features made LCDs practical for
television receivers.
WHAT
IS LED TELEVISION?
It is similar to an LCD TV;
however, it uses LED as the source of backlight. A light-emitting diode (LED) is a semiconductor light
source.
BY WHO AND IN WHICH YEARS WERE THEY INVENTED?
LCD: - The
exact date and inventor are not known. LCD TVs came to be after a series of
various inventions based on research and development by various people and big
electronics MNCs. Combined efforts of researchers, scientists, universities,
electronic giants and industrialists led to the LCD TV. However, James Fergason
is commonly and widely accepted as the inventor though he is not the sole
individual involved in the process.
LED: - In the
case of both commercial LED screens and domestic versions, several companies
have adopted the technologies at similar times. It is safe to say that no one
person or company "invented" the LED television although credit must
be given to the engineering teams who first applied LED technology to
television and video displays.
LED
VS LCD:-
An LED TV uses less power, provides
a brighter display with better contrast, a thinner panel, and lesser heat
dissipation than a conventional LCD
TV. This is because an LED TV uses light-emitting diodes for
backlighting versus CCFLs used
by conventional LCD TVs. An LED TV offers more colors, especially ones that use
RGB-LED backlighting. On average, LED TVs are priced higher than traditional LCD TVs that use CCFLs for backlighting. LED
TVs use energy-efficient light emitting diodes (LED) for backlighting. These
consume less power than cold cathode fluorescent lamps (CCFL) used in
traditional LCD televisions. Power savings are typically 20-30%.
WHICH IS MORE POPULAR?
As of now, the LCD
technology is extremely popular as people have dumped the conventional bulky
cathode tube TVs for the better option. Although huge numbers of people,
especially in poorer nations like India still use the old box-type TVs they are
slowly going out of usage as even big companies have stopped manufacturing them
due to low demand. An important point to note however is that even LCD TV users
are slowly but steadily switching to LED TVs due to various benefits they offer
like better picture quality, thinner panel, substantial electricity consumption
reduction etc. One of the reasons that deter the “aam aadmi” from opting for
LED is due to its slightly higher costing.
FUTURE OF BOTH TECHNOLOGIES:-
Various studies and reports
show for sure that the conventional cathode TVs are not going to be prevalent
any longer than a decade. Populations the world over are shifting to modern
technologies like the LCD and LED to stay with the times. As of now, the LCD
market is stable but the LED demand is on the rise. Having said that, it is
hard to forecast in the world of technology- because as we all know, every
second of the day, there is a new discovery/invention/development taking place
and it is surely going to be hard to keep up!
