Lifetime is tested at average 50% pixels on and is rated as Hours until Half-Brightness. The Display OFF command can be used to extend the lifetime of the display. Luminance of active pixels will degrade faster than inactive pixels. Residual (burn-in) images may occur. To avoid this, every pixel should be illuminated uniformly.
