5. ESTIMATED LUMINANCE LIFETIME
The luminance lifetime is the time from initial luminance to half-luminance.
This lifetime is the estimated value, and is not guarantee value.

Note1: Life time expectancy is mean time to half-luminance.
Note2: Estimated luminance lifetime is not the value for an LCD module but the value for LED
elementary substance.
Note3: By ambient temperature, the lifetime changes particularly. Especially in case the product
works under high temperature environment, the lifetime becomes short.
