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.

Conventionally, it was difficult to maintain parallelism between an optical filter and a PDP, and also the weight of the optical filter was put on the PDP.

With a PDP 10 and a frame 30 separately fixed to a bracket 20 connecting to a leg member 60, fix an optical filter 80 to the frame 30. As a result, the optical filter 80 is fixed with required parallelism maintained with the PDP 10, and also the optical filter 80 and the PDP 10 will not put their weight on each other, thus eliminating unnecessary loads on the optical filter 80 and the PDP 10. Also, unnecessary flaws and distortions in a casing 40 can be prevented during the product manufacturing.
