Abstract
The EL device includes a first electrode which is a transparent electrically conducting layer, a dielectric layer overlying the first electrode and a plurality of electroluminescent block members disposed in spaced relationship on the dielectric layer, each EL block member having a first surface disposed in contact with the dielectric layer and a distal second surface. A second or counter electrode which is formed of an electrically conductive layer is positioned in spaced relationship to the distal second surfaces of the electroluminescent block members. The dimensions of the electroluminescent block provide for preselected sonic isolation so as to provide for reduction of phonon waves of varying energies and increase the output brightness of the device.
