Note: Lifetime at typical temperature is based on accelerated high-temperature operation. 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.
Controller Information
Built-in US2066 controller.
