Abstract
An array of OEDs is arranged in rows and columns with a plurality of row buses and a plurality of column buses. Each of the OEDs has a first terminal coupled to an associated row bus and a second terminal coupled to an associated column bus. A switching circuit is connected to a shadow canceling row bus of the plurality of row buses. The switching circuit is constructed to receive a shadow canceling signal on a terminal thereof and to connect the shadow canceling row bus to a pull down potential in response to the shadow canceling signal, whereby all of the OEDs in the array, other than those associated with the shadow canceling row bus, are coupled to the pull down potential and discharged.
