Local Dimming Technology revolutionizes surgical imaging: Brighter, clearer and more accurate image reproduction

Sony’s unique Local Dimming Technology provides precise control over LED lighting sources for backlights in both light and dark areas. The outcome is exceptional clarity for surgical procedures, providing accurate reproduction of original images.

How does it work?

The reproducibility of black is improved thanks to an individual drive of different areas of the backlight. An excellent “peak brightness” of up to 1750 cd/m² and a contrast ratio of 1.000.000:1 is achieved by adding the power that is saved in the dark area to be put on top of the bright area.

Wide Color Gamut for accurate color reproduction

The Local Dimming technology allows for exceeding the boundaries of illumination, whereas conventional LCD monitors have a constant global backlight.

With Sony’s Local Dimming technology, colors can be clearly seen, even in dark areas, while conventional monitors without Local Dimming may not reproduce the colors correctly.

Benefits for medical applications

The following image shows the difference between the three types of displays. One with a regular backlight (left), another with Local Dimming technology in regular mode (middle), and the third one when changing to HLG (Hybrid Log Gamma), which is part of the BT.2100 standard for HDR signal reproduction.

A more accurate view

The excellent color and high contrast of original images help surgeons and OR staff see more details of complex surgical procedures and make it perfectly suited for surgical microscopy, endoscopy, hospital imaging, and more.
