Abstract
Techniques, devices, and systems are provided that allow for driving a device such as an OLED in various pulsed modes in which a momentary luminance greater than an apparent luminance at which the OLED is to be driven is used. The use of one or more pulsed modes allows for the lifetime of the OLED to be extended and reduces image sticking. Pulsed modes are also provided that allow for color tuning of the device by activating different portions of one or more emissive areas of the device.
