The half life of LED backlights. LEDs slowly dim over time; half life is the time, in hours, of how long the backlight can operate before its brightness is at 50% of what it originally was when first turned on. So if the half-life is rated at 50K hours, then the brightness of your backlight will be half as bright at 50K hours.

With different LED chip manufacturing materials, technologies and environment used, the LED life can vary from 20,000 hours to well over 100,000 hours. LED backlights have low power consumption and produce much less heat than other backlight technologies, which extends the durability and performance of the other display components.

Additionally, over the course of at most 24 days, backlight has supposedly been on for 540 hours, or 540/24=22.5 full days.
