THE
BENEFITS OF PLASMA TV
It is slim and
lightweight.
Plasma displays benefit from all the advantages of flat panel displays over
CRT displays. The picture tubes of traditional TVs are made of glass which
are of considerable weight and strength, where as the screens of flat screen
are made of light synthetic materials.
Glass
tube TVs have a great depth as a beam of electron has to travel a
considerable distance. As a result, the depths of the plasma TV is less and
hence can be hung from a wall.
They are
approximately one tenth the thickness of a CRT and one sixth the weight.
This becomes a major consideration as the display gets larger. A 40 inch
would easily weight more than 100 kilos and therefore be extremely unwieldy.
Philips
plasma TV has a depth of just 11.43 cm, (4.5 inches), one tenth of the depth
of a normal tube TV and weighs one-sixth of the normal tube
TV.
It provides a
wide viewing angle of 140o to 160o
The viewing angle of a wall hanging TV is very wide 140o to 160o.
Even in a
narrow passage, several persons can watch the TV up in the front.
Absolute flatness
Absolute flat surface means that the picture looks the same everywhere in a
room, whether you view it straight on or from the sides.
Traditional CRTs require an internal vacuum where an electron gun bombards
the phosphor on the interior of the glass screen with electron beam. Since the
CRT is essentially a vacuum tube its screen has to bear an atmospheric pressure
of about three tons. To enable it to sustain pressure, the display cannot but be
convex. But the image takes a bending due to the curvature of the glass.
One way of offering flat screen is by using thicker glass. However thicker
glass interferes with the transmission of sight, there by darkening the screen
and adding weight to CRT.
Wide screen
Flat TV manufacturers favour 9:16 aspect ratio, the standard aspect ratio 3:4
is also supported. The wide screen has the advantage that it could allow split
screen viewing. Two pictures can be viewed simultaneously, one on each half of
the screen. One big advantage of 9:16 aspect ratio is that the sides do not cut
off.
Reflections are reduced
Being that the number of reflections is reduced. Further the total glass from
any position is less. Glass tube TVs reflect much more light than the flat
surface because of the curvature of the glass. Conventional glass-tube TVs can
be made flat screened up to a certain size beyond 33 inches the curvature cannot
be eliminated.
Magnetic interference free reception.
When a speaker or any magnetic field is brought near the conventional TV
tubes, distortion is observed on the screen. This is because the path of the
electrons are deviated by the Magnetic fields. You can now position even the
largest speaker close to the plasma displays without the fear of picture
distortion as plasma technology is totally unaffected by magnetic fields.
The fact that plasma TV is not affected by magnetic fields make it ideal for
public displays.
Distortion free viewing
The flat surface eliminates distortion at the edges and gives a clearer, more
accurate picture. Since the entire plasma screen is illuminated at once, as
opposed to sequential scanning system in traditional TVs, image does not
flicker, making high quality picture more pleasing to the eye.
Future compatible
Plasma TVs are ready for the future. It is capable of receiving digital
broadcasts with the addition of an optional digital decoder.
High Resolution Picture
Triades of red, blue and green colours forming the plasma TV are made up of
over one million pixels. Advanced electronics control the individual chambers to
produce more than 16 million colours. The pixel combine to form a very high
resolution pictures, viewable from any angle under any lighting conditions.
Multimedia connectivity with its VGA capability
Plasma modules have a VGA level resolution (256 RGB
colours) created from
over two million colour palettes, making these excellent tools for the display
of computer graphics and effects .it can be the integrated to the multimedia
platform with high-tech, built in speakers using Dolby prologic surround
technology.
Combines high-end TV and monitor functions
The outstanding picture quality and dramatic impact of the set's large screen
format make it an unmatched display for advanced systems meeting the most
demanding home cinema expectations. In addition to its use for high-quality TV
viewing, the New Flat TV can also be used as a monitor to display computer
graphics and other images, with full VGA, S-VGA and X-VGA compatibility which
makes it an ideal tool for professional presentation and display purposes. Large
size and high quality of the display, together with the wide viewing angle, it
is ideal for multimedia and Internet applications, as well as for use with
larger audiences.
The New Flat TV has multi-standard reception, and is able to receive PAL,
SECAM and NTSC signals. It also has a VGA connector and supports VGA, S-VGA and
XGA display resolutions, making it an ideal solution for multimedia PC
presentations. This is implemented by the unique Philips-developed LIMESCO (LIne
MEmory Scan COnverter) integrated circuitry, which ensures full compatibility
with computer and video standards and provides optimum quality and full size
pictures without information loss. The LIMESCO technology provides an
intelligent, full-screen bit-mapping technique to automatically translates the
input resolution without loss of picture quality or brightness.
Advanced video signal processing circuits.
The numerous other picture enhancement technologies also include a gamma
circuit to compensate for the pre-correction introduced by the TV studio, and a
`feature box' containing advanced video signal processing circuits. These
include motion estimation compensation for smooth, natural reproduction of
movement in the picture, Philips' crystal Clear technology with Digital Noise
Reduction. In most cases these are proven signal-processing technologies, based
on the ICs and software algorithms which have already been developed for the
Philips range of CRT-based TV sets.
Separate electronics unit
Allowing the display unit of the New Flat TV to be kept as slim and compact
as possible, the set's main electronics are housed in a separate tuner unit .
This unit can be located in any convenient position within up to 15 metres of
the set. As well as contributing to a compact and attractive design, the use of
a separate electronics unit offers another important benefit: all the many
possible system connections are made at this unit, and only a single connecting
cable is needed to the set itself. The separate electronics unit will in most
cases be housed out of sight in a nearby cupboard, thereby eliminating the
profusion of untidy connecting cables which is a typical problem of high-end A/V
systems. The New Flat TV is also available as a stand-alone data and video
monitor without the separate electronics unit, for use in PC and multimedia
applications.
Real home cinema sound
A real home cinema viewing experience demands not just a large,
state-of-the-art picture, but also powerful, all-round sound to match. Meeting
this need, the New Flat TV has no less than six built-in loudspeakers which are
ingeniously integrated into the set's design. For users who want to create a
state-of-the-art home cinema system, Manufacturers offers a range of home cinema
components including digital A/V surround receivers able to decode multichannel
Dolby Digital or MPEG-encoded sources. When the New Flat TV is used as part of a
multi-loudspeaker home cinema system, all the set's built-in loudspeakers can be
switched into centre mode to handle the front centre sound channel. The tuner
box and the digital receivers have a matching design, ensuring a harmonised
appearance of the complete system.
Life-span of PDP
The
life-span of a PDP is estimated at about 30,000 viewing hours, the same as for a
CRT.
