Luminance stabilizing system to provide continuous stable display for medical images

A change in luminance affects gamma characteristics and therefore has adverse effects on diagnostic imaging. JVC medical monitors are equipped with a luminance stabilizing system that automatically compensates for luminance changes due to startup, temperature change, and aging.

Luminance stabilizing system λ-Sentinel

λ-Sentinel consists of a luminance sensor and a luminance control circuit. The luminance sensor attached in front of the screen constantly monitors and accurately stabilizes luminance on the screen surface by sending feedback to the control circuit.


  •  With luminance fluctuation caused by the LCD module taken into account, highly accurate luminance control is achieved.
  •  Actual luminance measurements including intermediate luminance are taken on the screen surface.
  •  Build-in luminance sensor enable calibration without attaching the calibration sensor.
