Abstract

A method for forming a pixel circuit includes forming transistors on a substrate; forming a passivation layer over the transistors; forming a contact hole to a source of a transistor; forming a transparent conductor that forms a contact in the contact hole and a resistor to control pixel current; and forming an organic light emitting diode (OLED) with an anode connecting to the resistor.
