Abstract (en)

[origin: EP0392918A1] The display screen comprises, on an insulating substrate, an electroluminescent layer and a photoconducting layer which are stacked, the assembly of these layers being interposed between transparent lower electrodes (12) pointing in a first direction (x) and upper electrodes (22) pointing in a second direction (y) perpendicular to the first, the upper and lower electrodes defining image points (26) at their intersection, the upper electrodes (22) comprising slabs (40) of dimension D in the first direction, in the region of the display points, and electrically interconnected by two access strips (42a, 42b) of width d with d<D/2, the access strips to a first slab being connected by a conductive passageway (46) parallel to the lower electrodes, the borders of these slabs (40) being situated inside the borders of the lower electrodes. <IMAGE>
