Abstract
There is provided a method for driving an organic light emitting diode (OLED) pixel circuit. The method includes applying a first signal to a terminal of the OLED when setting a state of the pixel circuit, and applying a second signal to the terminal when viewing the state. There is also provided a driver for an OLED pixel circuit, where the driver employs this method.
