Life Expectancy of Constituent Parts
This section describes the life expectancy of constituent parts (backlight,
power supply, internal cooling fan and touch screen) which make up to
BES1200-CD1.
■
TFT
Display
Backlight
Display brightness decreases over time with use. The expected operating
lifetime of the backlight time to reach 50% initial brightness) is 30,000 hours
(assuming continuous lit state at 25 degrees C). Actual lifetime before
replacement is about 30,000 hours, although this depends on operating
conditions.
■
Touch
Screen
The operating lifetime of the touch screen is approximately 1 million
operations (as tested by mechanical manipulation under 100g of force at a
rate of two presses per second)
