Abstract

An active matrix OLED pixel driver circuit comprises: a power supply connection to receive a power supply; an OLED drive connection to drive an OLED; an OLED drive transistor having an input, output and control connection, wherein said input connection is coupled to said power supply connection and said output connection is coupled to said OLED drive connection; a gate capacitor having a first plate coupled to said control connection of said OLED drive transistor and a second plate coupled to a common capacitor connection; a first select transistor having an input connection, an output connection coupled to said first plate of said gate capacitor, and a control connection coupled to a first pixel select connection of said OLED pixel driver circuit; an input capacitor having a first plate coupled to said input connection of said first select transistor and a second plate coupled to said common capacitor connection; and a second select transistor having an input connection, an output connection coupled to said first plate of said input capacitor, and a control connection coupled to a second pixel select connection of said OLED pixel driver circuit.
