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 colour reproduction, and quick response with virtually no motion blur. And yet it features a wide colour gamut, meeting ITU-R BT.709, EBU, and SMPTE-C broadcast standards, and conforming to the wider DCI-P3 colour gamut.*

Furthermore, the newly developed OLED processor with cutting-edge technology offers quality consistency, superb uniformity, and long-term reliability.

Sony optimizes the potential of the OLED panel using unique Super Top Emission OLED technology along with the dedicated OLED processor. The combination of these technological developments elevate the BVM-E, BVM-F, and PVM Series to a new level of next-generation master monitors and picture monitors, re-setting the industry’s ultimate reference point.

With Sony’s OLED fully unleashed, Sony starts a new and important chapter in professional monitor history.

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 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 colour 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 colour filters. This cavity structure uses an optical resonance effect to enhance colour purity and improve light-emission efficiency. In addition, the colour filter of each RGB also enhances the colour 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.

The OLED processor – Dedicated to eliciting full performance.

Accurate signal processing across all signal levels Accurate gamma control Superb uniformity control

Dedicated Sony’s OLED 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-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.

Advantages of Sony’s OLED Technology

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, 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, 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 Colour Reproduction

Sony’s Super Top Emission technology not only offers a wide colour gamut with its purity of the three primary colours, but also maintains this wide colour gamut throughout the entire luminance range. While all other display devices have limitations in reproducing accurate colours, 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 colours as well.

Advantages of Sony’s OLED Technology

Quick Response with Virtually No Motion Blur

The Sony’s OLED grey-to-grey 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.

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 colour management system.

Nonlinear Cubic Conversion colour management

The nonlinear cubic conversion colour management system of BVM-E and BVM-F Series master monitors use a unique 3D LUT (look-up table) to accurately reproduce the colour gamuts of each broadcast standard such as ITU-R BT.709, EBU, and SMPTE-C phosphor standards. In addition, the OLED’s wide colour gamut enables D-Cine emulation for digital intermediate work.*

* D-Cine is a colour gamut emulating the colour gamut described in SMPTE

RP 431-2-2007. The chromaticity of the green-red region is not covered in full; however, the colour shift is subtle in this region.

This feature is supported by the BVM-E Series only.
