Eg1.
• A display is used at 8 hours/day; ie. +/-2.920hours/year
• The display system is covered with a warranty period of 5 year
• The Guaranteed Backlight Lifetime of that model is 17.000hours.
• The Factory Calibrated Luminance cannot be achieved anymore after 4 year, thus
corresponding to +/-11.680hours
• Result: the backlight replacement is performed under warranty
Eg2.
• A display is used at 24 hours/day; ie. 8.760hours/year
• The display system is covered with a warranty program of 5 year
• The Guaranteed Backlight Lifetime of that model is 17.000hours.
• The Factory Calibrated Luminance cannot be achieved anymore after 2.5years, thus
corresponding to +/-21.900hours
• Result: the backlight replacement does not make part of the warranty coverage.
