Patent ID: 8264482

Claim:
A drive circuit for rapidly interleaving image data displayed on an EL device, the drive circuit comprising: a. a signal source that provides a plurality of image data signals, each image data signal being provided during a specified load period; b. a multiplexer for receiving the plurality of image data signals, and in response to a selection signal selecting one of the plurality of image data signals to provide a control signal that directs the EL device to emit light; and c. a controller causing interleaving of the image data during multiple display periods, each display period shorter than the load period; wherein the signal source provides the plurality of image data signals sequentially, the controller provides a succession of values of the selection signal in a selected phase relationship with the plurality of sequential image data signals for each EL light-emitting diode in the EL device, and the multiplexer comprises a drive transistor connected to a first power supply and a plurality of current control circuits; each current control circuit connected to a gate electrode of the drive transistor, and comprising a write transistor, a storage element and a read transistor.
