Abstract
Drive apparatus for an array of organic LEDs including first switches connectable between a current source or a rest potential, second switches connectable to a power source, an array of LEDs with each LED having a first contact connected to one of the first switches and a second contact connected to one of the second switches, and control apparatus connecting selected switches of the first switches to the current source while retaining all remaining switches of the first switches connected to the rest potential, and periodically connecting selected switches of the second switches, one at a time, to the power source to generate a desired image on the array.
