ABSTRACT:
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.
