Fully digitized high-quality images elude all attempts
Digital AccuDevice, the unique signal-processing circuit
developed by NEC
Digital AccuDevice generates advanced vividness
using a fully digitized signal-processing circuit.
LSIs packaged on the circuit are integrated into
three circuits to achieve the full digital sampling
of all input signals without any omissions.
Furthermore, all processing steps for video input
signals are fully digitized. Since there is no analog conversion process
involved and original video images can be processed digitally as they
are, there is no deterioration of the signal, and the high-definition
progressive expression and clear resolution conversion suppress noise
and produce breathtaking images.
Mass Area Superior Sampling Technology achieves high-definition progressive expression
All input signals are displayed using progressive expression.
In ordinary processing, interlaced signals are converted into
progressive signals, and the sampling of interpolation lines
are processed on the basis of brightness signals. With the
newly developed Mass Area Superior Sampling Technology,
color signals are sampled and interpolated together with
the brightness signals. The new technology produces sharp
expression without jagged edges or colour bleeding.
Vivid, breathtaking colours
The highest contrast ratio in the industry at
200:1 under bright conditions
PX-50XM4 and PX-42XM3 achieve the highest contrast ratio in
bright conditions in the industry, as a result of efforts to pursue
higher visibility under bright lights or in sunlight. Obtain vivid,
sharp video images regardless of the environmental conditions of
the locations. (As of July 2004)
AccuCrimson reproduces accurate red colour
AccuCrimson, employed in the front filter, is a technology for attenuating
the orange colour included in the wavelength for red, which is particular
to the plasma display. AccuCrimson clearly expresses the delicate
difference between cinnabar and red colours and reproduces natural
skin tones-tasks which are difficult with ordinary plasma displays.

Insatiable desire for vivid colour reproduction
The CCF method, a unique NEC technology,
and black stripes reproduce vivid, accurate colour
With the CCF (Capsulated Colour Filter) method, each pixel is
capsulated and embedded with color filters for the three primary
colours (RGB); the results are that the red, blue, and green colors
are reproduced more accurately. By providing black stripes on
the barriers between cells, a sharp black colour is also expressed.
By employing NEC's unique technology, vivid colours are reproduced
and a pure white color is expressed to reduce screen deflection.

The CCF improves the purity of colors by filtering the three primary colors (RGB).
Removal of unwanted light
The CCF removes the orange color, particular to plasma displays, emitted by
neon gas.
Reduced screen deflection
The CCF and the black stripes reduce screen deflection to produce a high
contrast ratio under bright conditions.
Optimized red color
The CCF suppresses the wavelength of the orange colour included in red to
reproduce a pure red color.
The highest capability for colour expression in the industry with 4,096 steps equivalent to
68.7 billion colours
By introducing Gamma-12, rich and smooth
expressions with 4,096 steps - the highest number
Mode 1
in the industry - are achieved in the respective colours
of R, G, and B to provide the industry's highest
capability for color expression equivalent to 68.7
billion colours in the dark portion. The expression
reproduces accurate, more faithful details.

The newly designed Scan Converter dramatically improves character readability
The Scan Converter converts input signals in
accordance with the resolution of the display. Since
sampling accuracy for the interpolation of data has
been improved by approximately 4 times, and its
conversion accuracy has also been improved by
approximately 4 times (compared to NEC's ordinary
products), small characters can also be displayed
uniformly with a dramatic improvement in readability.
With the digital zooming function, enlarged characters Ordinary expression
will not bleed or become fuzzy.
The Colour Tuning function adjusts specific colours
The Colour Tuning function adjusts specific colours, such as red,
blue, or green, individually without influencing the white balance.
Since the white balance remains stable, specific colours can be adjusted
depending on the video source or the purpose of use. For instance,
deepen the blue colour of the sea or the green color of leaves.

Expression with the Scan Converter
The new module is employed for high brightness
and low power consumption
The plasma display expresses colours with the following mechanism.
Certain voltage is applied to rare gas sealed on the inside and then the
phosphors are irradiated with the UV rays generated at that time. In the
new module, the phosphors are improved and the gas composition rate
is reviewed to drastically improve its luminous efficiency. Since a new cell
structure is employed where the grid barrier between the cells prevents
interference from the electrical discharge, and a new electrode structure
expands the effective discharge area, low power consumption, high
brightness, high contrast, and a long lifetime are achieved at the same

Long life panel
A panel lifetime of 60,000 hours has been achieved for all models.
*60,000 hour panel life is an approximate time for the display panel to reach half of it's original brightness.
The panel life is based on motion video as the input source and all display settings at factory default. The
time given does not imply any warranty beyond the products standard warranty.
