– Evolution of Viewing Angles
Continuing enhancement to meet critical user expectations
Since their market debut, TRIMASTER EL™ OLED (organic light-emitting diode) monitors have
proved extremely popular, and are now recognized as a de facto standard. As well as offering
characteristics superior to CRT monitors, TRIMASTER EL monitors continually evolve to meet the
expectations of critical users who demand professional-quality picture performance.
These ongoing improvements include the innovation of wider viewing angles, featured in the
new TRIMASTER EL OLED A Series: BVM-E250A, BVM-E170A, BVM-F250A, BVM-F170A, PVM-2541A,
and PVM-1741A.
This improvement reduces color shift by half*1 when compared with their predecessor models,
offering the industry-leading wide viewing angles in the professional flat panel market.
And it enables group monitoring – for example, video engineers or colorists can view the
display properly from many different angles – and hence allows more efficient content
creation activities.
Two of these new models offer additional benefits. The PVM-2541A and PVM-1741A are
equipped with a variety of convenient new features including new waveform capabilities,
vector scope, closed caption display, and camera focus in color.
If you require a portable solution, consider the improved PVM-741 7-inch*2 OLED monitor which
includes the same additional benefits as the PVM-2541A and PVM-1741A in a highly mobile
unit.*3 Now you can bring PVM OLED quality imaging with you, anytime, anywhere.
Designed for every professional need, it’s time you experienced the immense value of new
TRIMASTER EL monitors.

TRIMASTER EL – Self-emitting Display Device
TRIMASTER EL creates light by recombining an electron and a hole within certain organic materials. The process of emitting light
is extremely efficient when compared to other technologies currently used for display.
Its organic materials react to the control of the electrical current immediately, and do not emit light in the absence of an
electrical current. In this way, the OLED display panel features superb black performance and quick response to fast-motion
pictures. In addition, Sony’s OLED display panel delivers a wider color gamut.
Super Top Emission Technology
Sony’s Super Top Emission OLED panel is designed to deliver
light emission with the TFT layer on the rear side of the panel.
Therefore, the top emission structure offers more efficient light
emission than is typical with bottom emission structures where
TFT layers are placed on the front side of the panel, limiting
the light-emission aperture.
This Super Top Emission technology has a micro-cavity
structure which incorporates color filters. This cavity structure
uses an optical resonance effect to enhance color purity and
improve light-emission efficiency. In addition, the color filter of
each RGB also enhances the color purity of emitted light, and
reduces ambient light reflection.
Sony’s Super Top Emission OLED panel is completely sealed
by a glass substrate, and the electroluminescent layer is fully
isolated from outside air and moisture. This contributes to
stability and reliability.

Accurate gamma control
Superb uniformity control
Dedicated TRIMASTER EL Processor*
The BVM-E, BVM-F, and PVM Series of OLED monitors incorporate newly developed OLED-dedicated signal processors to elicit and
maximize OLED panel performance. This technology allows these TRIMASTER EL™ monitors to provide the level of performance
required for critical imaging. These processors accurately control gamma and uniformity, and deliver precision stability control.
* The PVM-741 is equipped with a different processing technology (ChromaTRU™).
Accurate gamma control
Since TRIMASTER EL panel can display a deeper black than
any other display device, the TRIMASTER EL processor controls
gamma accuracy (black reproduction) by increased signal
processing bit depth.

Advantages of TRIMASTER EL Technology
Accurate Black Reproduction
A key advantage of TRIMASTER EL is the fact that each pixel
can be turned completely off. No other display technology
is able to offer this. LCD either raises black luminance due
to intrinsic light leakage, or reduces black luminance with
artificial local dimming technologies. CRT always applies a
bias voltage to place the gun at the proper operating level.
All of these display devices have some limitation in accuracy
of black reproduction. In comparison, TRIMASTER EL is
capable of reproducing accurate black with each individual
pixel, enabling users to evaluate each picture image faithfully
to the signal.

Accurate Color Reproduction
Sony’s Super Top Emission technology not only offers a wide
color gamut with its purity of the three primary colors, but
also maintains this wide color gamut throughout the entire
luminance range. While all other display devices have
limitations in reproducing accurate colors, especially in the
low signal levels, TRIMASTER EL system is truly an ideal display
device for picture evaluation. With OLED, users see the details
in the blacks, and see the colors as well.
Quick Response with Virtually No Motion Blur
The TRIMASTER EL gray-to-gray switching speed (measured
in microseconds, μs) is much faster than that of the LCD
(measured in milliseconds, ms).* This fast response benefits
a variety of applications and uses. For example, in sports
broadcasting, when camera pans would become blurred
with an LCD, they remain sharp and clear with OLED. And with
moving titles or graphics, when text can be difficult to read
on an LCD, OLED displays clear text, regardless of speed or
direction.

Precision Imaging without Artifact
TRIMASTER EL monitors* incorporate the motion adaptive I/P conversion
method, which detects information from multiple present and past fields.
This is superior to conventional technology, which generally uses motion
detection in fewer fields.
With this technology, TRIMASTER EL monitors reproduce video signals
accurately without artifacts. You’ll appreciate the difference immediately –
for example, when there’s zero tolerance for failure in shooting, you can be
confident of fine patterns or delicate commercial logos.

system and by professionally trained human eye at the final stage of
manufacture prior to shipping. This quality control process provides
substantial consistency and uniformity among TRIMASTER EL monitors.
In addition, color reproduction of BVM monitor can easily and accurately be
duplicated to other BVM monitors using the Memory Stick™ copy function.
Color reproduction of every monitor is matched to the extreme, regardless of

Professional Display Engine
The high-precision signal processing engine has been developed to fulfill the master monitor criteria and is optimized to
maximize OLED panel performance. This engine incorporates 12-bit output accuracy at each process, and provides both a
high quality I/P conversion algorithm and a highly accurate color management system.
Nonlinear Cubic Conversion color management
The nonlinear cubic conversion color management system
of BVM-E and BVM-F Series master monitors use a unique
3D LUT (look-up table) to accurately reproduce the color
gamuts of each broadcast standard such as ITU-R BT.709,
EBU, and SMPTE-C phosphor standards. In addition, the
OLED’s wide color gamut enables D-Cine emulation for digital
intermediate work.*
* D-Cine is a color gamut emulating the color gamut described in SMPTE RP
431-2-2007. The chromaticity of the green-red region is not covered in full;
however, the color shift is subtle in this region.
This feature is supported by the BVM-E Series only.
