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. JVCKENWOOD's medical image displays are equipped with a luminance stabilizing system that automatically compensates for luminance changes due to startup drift, temperature change, and aging.

Luminance stabilizing system λ-Sentinel

λ-Sentinel 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.

Newly developed luminance stabilizing system λ-SentinelLuminance sensor


  • 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 provided with i2 models enables even simpler calibration without attaching the calibration sensor.

Note: λ-Sentinel module is built into the the ME/CCL Series i model displays.
