Interleaving drive circuit and electro-luminescent display system utilizing a multiplexer

An EL display system, comprising:

• a. an array of EL devices, each EL device emitting light in response to a control signal;
• b. an array of drive circuits for providing control signals, each drive circuit having a multiplexer for receiving a plurality of image data signals and, in response to a selection signal, selecting one of the plurality of image data signals to provide the control signal;
• c. a signal source for providing the plurality of image data signals, each image data signal being provided for a specified load period;
• and
• d. a controller for causing interleaving of the image data during multiple display periods, wherein each display period is 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.
