Sony releases first OLED field display.

Sony said it is bringing the "stunning technology that revolutionised" consumer displays to its line of professional monitors. The new PVM-740 is the first field display to use an organic lightemitting diode (OLED) display panel with Sony's own Super Top Emission technology to efficiently deliver superb high contrast and vibrant colour images, even in adverse lighting conditions.

Incorporating a 10-bit panel driver, the 7.4-inch high-resolution portable monitor creates life-like and smoother-than-ever gradation from dark to bright portions of a scene, such as during sunrise or sunset.

Its high-contrast imagery allows the deep black of a night scene to be accurately displayed without the black portion of the image being raised, even in a low-illumination edit suite. As the black colour is deep, peak brightness becomes more intense and can brilliantly express sparkling town lights and stars in the night sky.

Its blur-free, quick response to fast motion is perfect for sports or camera monitoring during panning and text scrolling. With its picture contrast greater than a CRT display, it is less affected by ambient light, allowing images to be viewed even in strong sunlight.


"Another breakthrough innovation from Sony, the PVM-740 is the industry's first OLED professional field monitor with Super Top Emission technology. With its excellent contrast, enhanced glare resistance, precisely vivid images and a full complement of functionalities, it sets the standard for critical field monitoring," said Paul Maroni, assistant general manager of Live Productions, Business Professional Products Asia Pacific, at Sony Asia Pacific.

Sony added that its ChromaTRU technologies and 10-bit panel driver work effectively to emulate colours and gammas of CRT monitors and to support broadcast standards (SMPTE-C, EBU and ITU-R BT.709). The PVM- 740 monitor is also equipped with Sony's feedback circuit, which works to monitor the light output and feedback information to ensure precise white balance. The system ensures consistent colour and gamma accuracy. Anti-reflection (AR) coating provides protection from scratches and enables a high transmission rate of the internal light source to keep the picture as bright as possible, while keeping reflection from ambient light to a minimum. As a result, when used in bright lighting conditions, high contrast is still maintained even in dark areas of the picture.

The versatile monitor can be used for a wide range of professional monitoring applications, including acquisition, field production, R&D, in outside broadcast trucks and even in 3D camera rigs with its flip mode. In the 3D rig, the monitor can flip a picture horizontally or vertically without frame delay. This feature is useful during 3D image acquisition using a 3D rig camera with a pair of 2D monitors. The monitor can be connected to the camera systems directly without the need for an external signal converter, making system integration simpler.

A unique native scan function reproduces images without changing the input signal's pixel count - mapping the pixel of the input signal on the panel pixel-to-pixel. For example, when an SD signal is input, the monitor reproduces the image at picture sizes of 646x487 pixels in 480i and 480p, and 768x540 pixels in 575i and 576p.

The PVM-740 is equipped with standard interface connectors: a composite video; a 3G/HD/SD SDI; and a HDMI interface. It accepts both SD and HD video formats. With the 3G-SDI interface, it accepts 1080/50p and 1080/60p formats, which is compliant with the SMPTE 425 standard, transmitting up to 4:2:2/10-bit 1080/60p and 1080/50p video data using one SDI cable. As sports and live production move towards a 1080p system, the single-link 3G-SDI system can be an ideal solution.

HDMI connectivity further expands the monitor's potential applications. For example, the PVM-740 monitor can connect with professional video systems such as Sony's XDCAM HD, XDCAM EX, NXCAM and HDV series. Consumer video products such as Blu-ray Disc and digital cameras can also be connected, ideal for Blu-ray video authoring or digital photo image previews.

With a simplistic design and rich in functionality, the new monitor also adds AC/DC operations, a convenient control panel with luminous and assignable buttons, a camera focus function, a waveform monitor, eight-channel audio-level meter, a variety of marker settings, and native scanning capabilities.

The PVM-740 monitor is available now.
