Half-life is the amount of time before the LED (LED backlight) will be half or 50% as bright as when it was first turned on. This is not the amount of time for it to burn out. Standard half-lilfes for LEDs range from 50K hours to 70K hours. The lower the current, the longer the half-life.

EL backlights aka: Electroluminescence (not recomened for new designs) has a half-life of 3K hours.
