A flexible display device has one or more flexible electrode assemblies.
Each of the electrode assemblies includes a hierarchical control
arrangement for selectively activating electrodes of the display device.
The hierarchical control arrangement includes high-level control elements
and low-level control elements, each of the high-level control elements
being operatively coupled to respective subsets of the low-level control
elements, which in turn are coupled to respective groups of the
electrodes. Exemplary control elements are microstructure elements
containing imbedded microprocessors or integrated circuits. The use of a
hierarchical control arrangement results in data signals having to pass
through fewer control elements when compared with single-level
arrangements. This increases operation speed and reduces power losses due
to voltage drops across control elements. In addition, the number of
connections to device(s) external to the display may thereby be reduced.
