The Story Behind Plasma Display
The concept for plasma display
panels was first conceived in July 1964 at the University of Illinois
(USA). The first displays were nothing more than points of light created
in laboratory experiments. From then on, the technology was developed
and improved and by the late 60's, it had become advanced enough to
allow the scientists to construct geometric shapes. Further development
was limited, scientists were restricted by the materials that were
available, so screens were small, and image quality was low. Today the
progression in high speed digital processing, materials and advance
manufacturing technology, has made full colour, bright plasma displays
possible. Once what was only thought of as Science Fiction is now
available and ready to use in a host of new and exciting ways.
What is a Plasma Display Panel and How Does it Work
| Plasma
technology is very different from that used in other display
systems in that red, green and blue lights are created in every
pixel, reducing the need for space. Charged electrodes
sandwiched between two glass panels react with tiny pockets of
inert gas that change to a state of plasma. This process results
in the production of UV light, which in turn reacts with red,
green and blue phosphor in each pixel to emit visible light.
Unlike traditional displays, where the image is scanned across
the screen, plasma technology uses pixels that are all
"lit" at once. Therefore, having no electron beam,
back lighting or light polarization, the image is inherently
sharper, brighter and perfect from edge to edge. |

Screen-to-Chassis Ratio
| Unlike
traditional monitors or projection displays, plasma boasts
extraordinarily slim dimensions relative to its generous screen
size. Which means, screens can be installed almost anywhere. |
 |
Lightweight and Installer-Friendly
| In
addition to their slender proportions, screens are also light in
weight when compared with a conventional monitor, making them
installation-friendly in either wall or ceiling-mounted
applications. |
 |
Wider Viewing Angle
| Another
important characteristic of plasma, is its effective visual
field angle, which is in excess of 160 degrees (both
horizontally and vertically). This enables spectators, for the
first time, to enjoy sharp, on-screen images from virtually any
viewing point, rather than simply front-on. |
 |
Accurate Display Characteristics
| The
use of a true flat-panel screen ensures images displayed are
always perfect and distortion-free. Instant set-up with
convergence-free operation assures the image quality will always
be the same every time the plasma is switched on. |
 |
Free From Magnetic Interference
| As
plasma screens are not affected by magnetic fields, the
PDP-502MXE can be sited close to loudspeakers without the fear
of screen distortion, generally caused by magnetic interference. |
