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

BPC-6671.

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)
