PVM-740
Professional Video Monitor
The PVM-740 is a new type of 7.4-inch* high-resolution (960 x 540 pixel) portable monitor which incorporates an Organic Light-Emitting Diode (OLED) display panel with Sony's unique Super Top EmissionTM technology. Thanks to the nature of the OLED display panel and Sony's Super Top Emission technology, the PVM-740 offers outstanding high-contrast images for example, the deep black of a night scene can be accurately displayed and the black portion of an image is not raised even in a low-illumination edit suite. As the black colour is deep, peak brightness becomes higher and can brilliantly express sparkling town lights and stars in the night sky. On the other hand, the high-contrast, low-reflection capabilities of the PVM-740 achieve monitoring in bright sunlight of delicate, clearer images during outside broadcasting and field production performance that is difficult to achieve with CRTs and LCDs. Incorporating a 10-bit panel driver, Sony's Super Top Emission OLED display panel creates lifelike and smoother-than-ever gradation from dark to bright portions of a scene, such as in a sunrise or sunset. Also, an excellent blur-free quick response to fast motion benefits a variety of applications and scenes, e.g., sports broadcasting, monitoring of camera panning, and text scrolling. In addition to the high-purity deep colour reproduction characteristics inherent in Sony's Super Top Emission OLED display panel, two other elements Sony's 10-bit panel driver and ChromaTRU technologies work effectively to emulate the colours and gammas of CRT monitors, and to support broadcast standards (SMPTE-C, EBU, and ITU-R BT.709). Incorporating a compact, lightweight, and robust aluminum die-cast body, the PVM-740 suits many different indoor and outdoor applications. The PVM-740 is equipped with standard interface connectors a composite video, 3G/HD/SD-SDI, and HDMI which accept a variety of video signal formats from PAL/NTSC up to 1080/50p and 60p. The attraction of the PVM-740 goes beyond these qualities to also include much smarter and more convenient features and functions: DC/AC operation, a convenient control panel with luminous and assignable buttons, a camera focus function, a wave form monitor and an 8-channel audio level meter, a variety of marker setting, a native scan, and a flip function. This PVM-740 is ideal for a wide range of professional monitoring applications including use in an editing studio, outside broadcast, acquisition, field production, and even research and development.

Superb Picture Performance with an Optimized Combination of Sony's Technology
The organic light-emitting diode (OLED) is a self light-emitting device. Sony's 7.4-inch high-resolution (960 x 540 pixel) Top Emission OLED display panel is designed to emit light efficiently and offers high-contrast, high-purity deep colour reproduction. Thanks to the nature of the OLED display panel and Sony's Super Top Emission technology, the PVM-740 offers superb picture performance: its deep black, in particular, is outstanding. The characteristics of high-contrast, high-purity deep colour reproduction can add impressive reality to an image. By optimally combining OLED display panel technology with 10-bit panel driver and Sony's unique ChromaTRU technologies, the PVM-740 monitor achieves superb picture quality and offers many user benefits. Deep Black and High-contrast
A feature of the OLED display panel is that it does not emit light when no electric current is applied or when a black signal is received. In this way, the deep black of a night scene can be accurately displayed and the black portion of an image is not raised even in a low-illumination edit suite. As the black colour is deep, peak brightness becomes higher and can brilliantly express sparkling town lights and stars in the night sky. On the other hand, the high-contrast, low-reflection capabilities achieve monitoring in bright sunlight of delicate, clearer images during outside broadcasting and field production performance that is difficult to achieve with CRTs and LCDs. Incorporating a 10-bit panel driver, Sony's Super Top Emission OLED display panel creates lifelike and smoother-than-ever gradation from dark to bright portions of a scene such as in a sunrise or sunset.
High-purity Deep Colour Reproduction
Sony's micro-cavity structure using an optical resonance effect reduces unnecessary ingredients and enhances the colour purity of each RGB colour. And, in this structure, each RGB colour filter has further functions to reduce unnecessary colour ingredients. Thanks to the combination of Sony's micro-cavity structure and the RGB colour filters of the Super Top Emission OLED panel, colour purity is dramatically enhanced and stunning deep colour can be reproduced. This combination is also effective in reducing ambient light reflection, and consequently deep colour reproduction can be achieved without colour degradation, particularly in bright environments.
Quick Response with Blur-free Motion
Because the OLED electroluminescent layer inherently responds to any electrical current input, it emits light immediately. By this mechanism, excellent quick response characteristics can be achieved in fast-motion images. This efficient blur-free, fast response benefits a variety of applications and scenes, e.g., in sports broadcasting, monitoring of camera panning, and text scrolling.
Extremely High Peak Brightness
Sony's Super Top Emission structure takes emitted light from the other side of the TFT circuit without limiting the circuit's aperture ratio. This method offers more efficient light emission. In addition, Sony's Super Top Emission is a micro-cavity structure and incorporates colour filters. The micro-cavity structure improves efficiency and increases the brightness of emitted light. Unlike a LCD, but similar to a CRT, the peak brightness is higher than that of an all-white image, and yet the black is deep. In this way, Sony's OLED display panel achieves extremely high peak brightness and can clearly display brilliant, sparkling images, giving reality to image texture.
Agile Motion in Low-temperature Climate
As Sony's OLED electroluminescent layer is a solid type of layer, performance is maintained in any climate, and the speed of response is unaffected by low temperatures*.

Sony's Super Top Emission (STE) Technology Offers Efficient Light Emission
The typical structure of an OLED display panel is a bottom emission structure. This type of structure employs a metal cathode and a chemical desiccant to protect the OLED layer from air and water. It takes light emission from the TFT layer and, due to the structural limitation of the TFT layer's aperture ratio, the amount of light emission is restricted. Sony's Super Top Emission takes light-emission from the other side of the TFT layer. This top emission structure offers more Top Emission Structure

Sony's Micro-cavity Structure Enhances Colour Purity
Sony's Super Top Emission technology is a micro-cavity structure and incorporates colour filters. Each RGB colour has a different wavelength. Sony's micro-cavity structure provides different emission layer thicknesses corresponding to the
wavelength of each RGB colour. The micro-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.
