Backlight RunTime: This is time in hours that the back light has
been on. A common question is: How much longer will the
backlight last? The backlight will typically last a very long time,
but will only be able to hold a calibrated output of for 17000
hours, after which time it will become slowly dimmer. For
displays calibrated at, an estimate of how long it will be before a
backlight replacement is needed = 17000 hours – backlight age.
Firmware Revisions: This is the runtime firmware that is loaded
in the display. This information may be helpful when there is a
problem.
Internal Temperature: This is the temperature inside the display.
It starts out at about the ambient temperature when the display
backlight is first turned on, then rises slowly to a steady-state
temperature as the display warms up. Changes in light level due
to temperature variations are completely controlled by the I-
Guard sensor on the front of the display.
Current Luminance Value: This is the current luminance value of
the display. It may vary a bit from time to time, for the display
continuously calibrates itself to meet the target luminance value.
