Sony is capable of extraordinary innovation in reference monitor development, as the
company builds on over 30 continuous years of BVM master monitor experience, and is the
world leader in OLED display devices and signal processing engines.
Sony has developed these 24.5-inch and 16.5-inch OLED display panels for critical
professional use. The OLED is a self-emitting device, and can deliver deep black, highcontrast, accurate color reproduction, and quick response with virtually no motion blur.
And yet it features a wide color gamut, meeting ITU-R BT.709, EBU, and SMPTE-C broadcast
standards, and conforming to the wider DCI-P3 color gamut.*

Sony’s OLED – Self-emitting Display Device
Sony’s OLED creates light by recombining an electron and a hole within certain organic materials. The process of emitting light
is extremely efcient 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 efcient 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 lters. This cavity structure
uses an optical resonance effect to enhance color purity and
improve light-emission efciency. In addition, the color lter of
each RGB also enhances the color purity of emitted light, and
reduces ambient light reection.
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.

Dedicated Sony’s OLED Processor*
The BVM-E 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-740 is equipped with a different processing technology (ChromaTRU™).
Accurate gamma control
Since Sony’s OLED panel can display a deeper black than
any other display device, the OLED processor controls
gamma accuracy (black reproduction) by increased signal
processing bit depth.
Superb uniformity control
Sony’s OLED processor offers superb uniformity across all signal levels at every point of the screen. At the factory, OLED-panel
uniformity is precisely measured and corrected using a proprietary RGB LUT (look-up table) adjustment system.

Accurate Black Reproduction
A key advantage of Sony’s OLED 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 (as shown in the following graph),
or reduces black luminance with articial 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, Sony’s OLED 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, Sony’s OLED 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 Sony’s OLED gray-to-gray switching speed (measured in microseconds, μs) is much faster than that of the LCD (measured
in milliseconds, ms).* This fast response benets 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 difcult to read on an LCD, OLED displays clear text, regardless of speed or direction.

High Contrast Performance
Sony’s OLED delivers the best contrast performance in all ambient light conditions compared to other display devices. From
dark environments to bright environments, black is black.
An LCD cannot display an accurate black in a dark environment due to intrinsic light leakage, and a CRT screen becomes
whitish in a bright environment where ambient light enters the thick glass on the surface, affecting the blacks of the image with
internal reection.

Professional Display Engine
The high-precision signal processing engine has been developed to fulll 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 master monitors uses 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.
Nonlinear Cubic Conversion color management system
Cutting-edge I/P conversion with low process delay
Sony’s original I/P conversion technology used in the BVM
Series minimizes processing artifacts found in typical upconversion processes. This has been improved in the BVM-E
Series so that an interlaced image is displayed accurately
and faithfully.
12-bit output accuracy signal processing
The BVM-E250 and BVM-E170 use a 12-bit display engine,
which allows images to be reproduced with high precision for
display accuracy.
