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.

Disclosed is a light emitting device (1) comprising a rectangular element (10) mounted upon a mounting substrate (20) via a heat-melted connecting material, wherein second substrate electrodes (3) are formed conforming to the recesses (2c) of a first substrate electrode (2) and a portion of the outer periphery of the first and second substrate electrodes (2,3) is provided with first extended sections (2b) that extend farther outward than the outer periphery (gs) of the aforementioned element (10). The aforementioned first extended sections (2b) are formed in at least one or more locations per one side of the outer periphery (gs) of the aforementioned rectangular element (10); the aforementioned first substrate electrode (2) is provided with second extended sections (2d) that are formed on at least one of both ends of the aforementioned recesses (2c) flanking the first extended sections (2b) of the aforementioned second substrate electrodes; and the aforementioned second extended sections (2b) extend farther outward than the outer periphery of the aforementioned element (gs).

A series spark gap is triggered such that in parallel with partial spark gaps (1, 2) of the series spark gap there are coupled first voltage distribution means. Further, at least in one partial spark gap (1, 2) there is arranged an additional electrode (10) whose voltage is set to a given level by means of second voltage distribution means. The voltage level of the additional electrode (10) is changed by disturbing the voltage distribution of the second voltage distribution means. Thus the spark gap between the main electrode (6a, 6b) of the partial spark gap (1) and the additional electrode (10) will be ignited. Capacity of the second voltage distribution means is lower than that of the first voltage distribution means and consequently the voltage acting over the first voltage distribution means does not change significantly. Thus the voltage determined by the first voltage distribution means acts over the spark gap that is between the additional electrode (10) and the second main electrode (6a, 6b) of the partial spark gap (1) and that will also ignite, which further results in the supply voltage (U) acting only over the second partial spark gap (2), whereby a spark-over will also occur therein.
