Trends in Consumer Television
With technology changing and advancing at a rapid pace, it's easy it lose track of new
or improved consumer electronics. Television is a great example of this -- in the past
seven years, liquid crystal display (LCD) televisions have overtaken a market that was
dominated by cathode ray tube (CRT) televisions for almost eighty years. Today’s
television buyers are finding they get bewildered when the subject turns to upgrading
their favorite news/entertainment delivery device.
In fact, buying a new TV has quickly become one of the most confusing and
challenging purchase decisions that consumers now face. Between the transition to
digital TV and HDTV programming, and the overabundance of TV types,
technologies, and terminologies, it’s no wonder modern TV buyers draw a blank. A
trip to your local consumer electronics store yields a host of technologies and terms to
describe them: Plasma, LCD, LED, Flat Panel, HDTV, CRT, Contrast ratio, and the
list goes on….
Most consumer electronics vendors sell TVs using several display technologies so that
they’re able to offer consumers the widest variety of TV sizes, shapes and. most
importantly price points.
But what is the current state of the art of television and what are the driving forces
behind it?
The CRT TV
The cathode ray tube (CRT) was invented in 1897, the commercial CRT television developed in the 20s and 30s and until the late 1980s there was no commercial television based on any other technology. The CRT TV is a hot, heavy, power-hungry box that sat in the corner of the living room of American homes for almost four generations, and is still available. 60% of American homes still have them due to their advantages, they are:
inexpensive to buy,
inexpensive to fix
simple to hook up to peripherals (such as DVD players)
3
While CRTs are still available and can still be seen side-by-side with newer
technologies, and 60% of American homes still have them. [4], it is considered a
moribund technology. Why? Because of three main limitations:
1. CRT screens are curved glass, thus:
the picture is distorted when viewed at certain angles
the screen is prone to reflection or glare
there is a maximum of about 32” screen size as the screen then becomes
too fragile.
2. the cathode ray tubes themselves are large, CRT TVs are almost as deep as they
are high, this leads to an inescapably bulky TV (a typical 32” CRT TV is 21.8”
wide x 29.6” high x 25.9 deep; 116 pounds) [1].
3. it is an inherently analog technology; to take advantage of the digital
broadcasting a digital tuner is required.
These functional limitations were superseded by the innovations of flat panel display
technology: Liquid Crystal Display and plasma TVs.
HDTV
The initial growth of the flat panel display market coincided with a government
mandated switch of broadcasters from analog to HDTV signals in the US and Canada
[2]. With the introduction and standardization of HDTV in the late 1990s LCD and
Plasma TVs took precedence over CRT TVs because they were perfectly poised to
plug in to the digital market. These TV technologies also allowed much smaller and
lighter TVs than the CRT technologies, whetting the consumer appetite.
The current HDTV market currently offers two distinct choices in display
technologies: plasma, traditional LCD [3]. Choosing between them is complicated,
they are competing technologies both of which achieve similar features (i.e., bright,
crystal-clear images, super color saturated pictures) and come in similarly sized (up to
65” screen width and 3.5” depth) flat screen casings [4].
4
Plasma TV
Plasma display is a flat screen technology in which each pixel on the screen is
illuminated by a tiny bit of plasma (charged gas) and the whole encased between two
thin sheets of glass. It that uses hundreds of thousands of tiny cells lined with
phosphor that are full of inert neon gas. Charging the gas with an electrode causes it
to glow and produce light. The amount of charge determines the intensity, and the
combination of the different intensities of red, green and blue produce all the colors
required (see Figure 1).
Figure 1: A plasma pixel
Each pixel cell is essentially an individual microscopic florescent light bulb. Three
cells make up one pixel (one cell has red phosphor, one green, one blue), and each
plasma screen has millions of pixels.
A plasma screen is more like an old CRT screen, since the images are created by
excited phosphors. As a result, plasma TVs can generate more colours (billions as
opposed to 16.7 million for LCDs). They can also create darker blacks, simply by not
activating the phosphors in the dark part of the image [5].
5
Due to the nature of how the plasma TV illuminates the screen, there are some
technical limitations [6]:
1. screens are subject to image retention (commonly referred to as "burn in" or
“ghosting”), if the same image is displayed long enough. While this could be
permanent in the early plasmas, it will fade in time with modern plasma
displays.
2. plasma image generation is an active phenomenon, so the phosphoric elements
in plasma displays fade over time. A 20,000 hour half-life for the plasma screen
is common. There is no way to replace these screens the display simply
continues to grow dimmer with use.
3. large screen plasmas consume a lot of power, a 60” Panasonic plasma TV
consumes 675 watts.
What is an LCD?
Now, imagine a piece of material that can be clear as glass or completely black so that
no light can pass through. Also imagine that you can electronically control it to be
clear or black. That is the basic idea behind a LCD.
You sandwich a layer of liquid crystals (LC) – crystals which alter their shape in
response to an applied electric current, between two pieces of transparent material
along with some clear electrodes. The size of the current applied, and thus the degree
to which the liquid crystals change shape determines how much light each cell will
transmit to the viewer. Now you can control how much light passes through the
material.
Then take a flat panel containing a grid of millions of sandwiched tiny LC shutters, or
cells, together with their millions of tiny electrodes and cover it with a color light
filter. The filter contains tiny red, green and blue areas. Now you have a LC display, or
LCD and the millions of tiny cells are the pixels (see Figure 2).
6
Figure 2: An LCD pixel
Through this, array you shine a very bright light. The backlight initially used to shine
through the LCD was CCFL (Cold Cathode Fluorescent Lighting) technology.
Since LCD pixels can be made smaller than plasma pixels, this backlighting
characteristic makes LCD screens generally brighter and crisper than plasma screens.
Although blacks are not as dark as those generated by plasmas because even when the
liquid crystals are made to block the light, some still gets through [5].
CCFL-LCD TVs have natural advantages over Plasma TVs in the following areas:
no burn-in susceptibility
longer display life (CCFLs rated at 40 000 hours half-life) and if the CCFL
tubes can be replaced, the display is good as new
higher light output (brightness). The LCD looks better in brightly lit rooms due
to the ability to produce a naturally brighter image
about half the power consumption of a plasma TV, a 60” LCD consumes 330
watts
Limitations of CCFL-LCD in comparison with plasma TV [7]:
1. CCFLs have a limited color gamut, 16.7 million as opposed to the billions of a
plasma display, it is rated 75% of NTSC standards [8]
2. blacks are not as dark as those generated by plasmas, hence a lower contrast
ratio
7
The natural question to ask is “can the benefits of each of the two separate
technologies be combined”? The answer is yes, with the Samsung 60” 8000 Series
television.
Technical Overview: the 60” LED LCD 8000 Series
The Samsung 60” 8000 series television is an electronic display device that transmits
the light from an LED light source through an LCD (Liquid Crystal Display) to create
the final image that the viewer will see on the screen. A TV that enhances the natural
advantages of the LCD TV and uses LED technology to rival the image quality of
plasma TVs (see Figure 3).
Figure 3: the 60” LED LCD TV

What is LED Backlight?
A LED (Light Emitting Diode) light source is used to replace the CCFL technology
used previously. An LED is simply a device which emits visible light when an electric
current is applied to it. The use of an LED light source as backlighting in LCD is a
new innovation which differentiates this television from other technology, (see
Figure 4).
Figure 4: CCFL backlight vs. LED backlight
In a further innovation, the LED source is also placed around the edges of the display
(see Figure 5). While edge-lit is not that different. The advantage of edge-lit TVs is
that they are even more power efficient, and they can be very thin.
Figure 5: back lighting and edge-lighting

The edge lighting diminishes overall width of the display casing, the allowing the
technology to achieve 1.3” thickness and a weight of only 55 lbs. with the stand (see
Figure 6).

Features and Benefits of the LED LCD TV
The performance improvements by replacing the fluorescent CCFL with the LED
light source are primarily:
energy efficiency (the LED backlight is 30% better at converting electricity to
light than the CCFL)
reliability (LEDs are rated over 100,000 hours of life, CCFLs at 40,000 hours)
brighter pictures. This is important if you’re planning to use your LED LCD
TV in a room that is brightly lit.
improved color gamut, while not in the billions of the plasma range, the 8000
series is quantum improvement over the CCFL, it is rated 100% by NTSC
standards [8]
While table stands are a standard way to display LCD units, the edge lighting allows
such a slim, light-weight technology, you can mount your flat-panel display on almost
any wall in your home for a better aesthetic effect:
Flat Wall Mounts allow you to maximize the space-saving
Tilt Wall Mounts enable you to place your TV above eye level, readily viewable
from anywhere in the room.
Articulating Wall Mounts use swivel arms to render the LCD unit flush with
the wall-and out of the way-when not in use. Pulled out, this mounting allows
you to turn the display 120° to either side and up to 10° up or down.
LED backlighting improves dynamic contrast levels to plasma-topping levels.

Glossary Brightness – is a measurement of the amount of light the LCD display produces. It is
given in “nits” [one “nit” is one candela per square meter (cd/m2)].
CCFL (cold cathode fluorescent lights) – a light source for LCD screens similar to
the fluorescent tubes for home use but smaller. Also called a "cold cathode
fluorescent tube" (CCFT), it weighs more and uses more power than LEDs, which are
increasingly superseding them.
Color Gamut – The entire range of colors available on a particular device such as a
monitor or television. Televisions are generally rated on their color by the percentage
of colors out of a color gamut that are possible. Thus, a television that is rated at
100% NTSC can display all of the colors within the NTSC color gamut. A screen with
a 50% NTSC color gamut can only represent half of those colors.
Contrast ratio – the ratio of the luminance of the brightest white to the darkest black
that the display is capable of. A higher contrast ratio means a sharper picture. A ratio
of 500:1 is the bare minimum – the higher the better.
CRT (cathode ray tube) – is a specialized vacuum tube in which images are
produced when an electron beam strikes a phosphorescent surface.
CRT TV – an electronic image display device that uses the CRT to produce the final
image. Picture quality and color definition are good. Product lifespan is also regarded
as good although they are prone to screen burn issues. CRT TVs are cheap to make
but many larger manufacturers have ceased their production as a result of consumer
demand for newer alternatives.
Flat Panel – a thin display screen for computer and TV use that first flat panels
appeared on laptop computers in the mid-1980s.
Half-life – the time when the phosphors in a plasma screen will glow half as brightly
as they did when the set was new.
16
HDTV (high-definition television) – a TV display technology specifying an image
resolution of 1920 by 1080 pixels (progressive scan lines) for the highest, and 720 and
1080pixels for the lowest HD resolutions . It is a TV technology that enables picture
quality similar to 35 mm film and CD-level audio. Blu-ray discs are 1080p.
LCD (liquid crystal display) – a flat panel display technology that uses the light
modulating properties of liquid crystals. Liquid crystals do not emit light directly.
Since all the picture elements are enclosed in the flat LCD array, these televisions can
be made much more compact than the older CRT TVs.
LCD TV – a flat panel electronic display technology that uses the LCD to compose the picture elements. LCD TVs consume much less power than plasma displays because they work by blocking light rather than emitting it. All modern LCD TVs are wide screen high-definition TVs (HDTVs). LED LCD TV – is an electronic device that transmits the light from an LED light
source through an LCD (Liquid Crystal Display) to create the final image that the
viewer will see on the screen. It uses LED backlighting instead of the CCFLs used in
other LCD televisions. The correct name for LED TV is LED-backlight LCD
television.
NTSC (National Television Standards Committee) – an organization responsible
for developing, in 1953, a set of standard protocol for TV broadcast transmission and
reception in the United States.
Pixel – the basic unit of illumination on a display screen such as a television screen or
computer monitor, one of many from which an image is composed.
Plasma TV – a flat screen display technology in which each pixel on the screen is
illuminated by a tiny bit of plasma (charged gas) and the whole encased between two
thin sheets of glass, also called "gas discharge display". It that uses tiny cells lined with
phosphor that are full of inert ionized gas (typically a mix of xenon and neon). Three
cells make up one pixel (one cell has red phosphor, one green, one blue). Charging the
gas with an electrode causes it to emit ultraviolet light, which causes the phosphor to
emit color. The amount of charge determines the intensity, and the combination of
17
the different intensities of red, green and blue produce all the colors required.
Reflection – (or glare) the light reflects back at the viewer from the glass of a
traditional CRT TV. The same is true of a plasma TV. LCD TVs, on the other hand,
are not reflective
