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.
