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
Note3: By ambient temperature, the lifetime changes particularly. Especially, in case the product
elementary substance
elementary substance.
works under high temperature environment, the lifetime becomes short.
