to an operatively rear surface of the first electrode 58 the phosphor layer 60 is encapsulated in a dielectric layer 62 it is to be noted that the dielectric layer 62 overlies the phosphor layer 60 of each of the various elements 56 of the electroluminescent illuminating arrangement 54 finally a second operatively rear electrode 64 which once again is in the shape of the image on the panel 52 to be illuminated is applied to the dielectric layer 62 in register with its associated phosphor layer 60 the electrode 64 is of any suitable conductive material for example silver it will be appreciated that the electrodes 58 and 64 together with the dielectric layer 62 and phosphor layer 60 sandwiched between them form a structure having a capacitive impedance when an alternating electric field is applied to the electrodes 58 and 64 phosphorescence of the layer 60 occurs this occurs as a result of once the electric field has been removed atoms in the layer 60 returning to their ground state by releasing energy which is in the visible spectrum of light it is also to be noted that the connection to each of the electrodes 58 and 64 have been omitted from fig3 for the sake of clarity reference is made to australian patent no 741427 where the connections are described in greater detail the artwork 50 is driven by one or more driver circuits 66 fig4 each driver circuit 66 in turn is controlled by a controller board 68 the controller board 68 receives commands from the game controller 36 via a sequencer 70 the controller board 68 receives electrical power from a high voltage.
