ABSTRACT:
An addressing scheme is provided for a display having an array of current driven pixels. An input voltage is used for generating a desired source-drain current using a transistor operated with low duty cycle. This source-drain current is then passed through a drive transistor and the resulting gate-source voltage is stored on a capacitor for subsequent driving of the display element.
