RightLight Service
The RightLight service provides backlight stabilization, DICOM calibration, and auto and
manual conformance testing, and also reports current white and black levels. You can
complete these tasks on Dome Ex, Dome GX4MP, and Dome Sx displays:
• Set a target white level for displays
• Equalize the black level across displays
• Set a desired response function
• Specify ambient light in the viewing area
• Set alerts for auto and manual DICOM conformance and white level tests
• Perform manual conformance tests with the photometer
• View current conformance status and manual conformance test results
RightLight automatically calibrates the display at regular intervals. Calibration adjusts
the response of the display to conform to the function you specify. There are four calibration
response functions, one of which is a correction to the DICOM Grayscale Standard
Display Function.
DICOM calibration is based on the display’s unique characteristic curve, stored in the unit at
the time of manufacture. RightLight routinely checks how well each display conforms to
the DICOM standard and calculates a Luminance Uniformity Metric (LUM) value that
indicates the degree of conformance.
You can set your preference for the panel appearance of Dome Ex, Dome GX4MP, and
Dome Sx color displays. (Go to the Color tab of the RightLight Panel Configuration.) Use only
the LCD II photometer to perform color calibration on this set of Dome displays.
