Abstract
There is provided a circuit for driving a current mode light modulating device. The circuit includes (a) a capacitor for storing a data voltage, (b) a field effect transistor (FET) controlled by a signal on a scan line, for coupling the data voltage from a signal line to the capacitor, and (c) a current source, controlled by the stored data voltage, for driving the device with current provided from a power line. The power line is in a plane that is geometrically parallel to a plane within which the scan line is located.
