activatable sections each column section may be selectively activated or deactivated depending on whether defects are associated with a given section application_number US 45394503 A description referring to fig1 the backside of a display 11 may be made up of a plurality of cathode columns 10 12 14 and 16 that run in a first direction and a plurality of anode rows 22 which extend generally transversely thereto each set 23 of three rows 22 may form a pixel that emits three different colors to form an appropriate color gamut in the illustrated embodiment each color is produced by a light emitting device arranged at the intersection of a column 10 12 14 or 16 and a row 22 in other embodiments other layouts may be possible each pixel is formed in the region where a cathode column 10 12 14 or 16 overlays an anode row 22 when appropriate potentials are applied between the cathode 10 12 14 or 16 and an anode row 22 light is emitted into the page in fig1 in one embodiment of the present invention the cathode columns 10 12 14 and 16 may be formed of aluminum the rows 22 may be formed of indium tin oxide ito so that they are both conductive and substantially light transmissive referring to fig2 a pixel 32 of a passive matrix light emitting device includes a cathode column 10 and an anode row 22 that sandwich a light emitting layer 24 in one embodiment of the present invention the layer 24 may be an organic light emitting device oled when appropriate potentials are applied between the cathode column.
