Display Brightness Half-Life

An important characteristic of an LED backlight

is the brightness half-life, which is the time

measured in hours that the brightness output

will decrease by half after running the LED

backlight at full brightness. The decrease in

brightness will not substantially decrease after

the half-life time has elapsed. Most displays

have a half-life of around 50.000 hours (or 5.7

years). Some of the brighter displays can have

a half-life of 20.000 hours or less.

Bright Idea: The brightness life of the display

can be dramaticallyincreased and burn-in can

be mitigated by allowing the screen saver to

dim and/or turn off the display when not in use.
