<p>A solid-state display device or indicator producing a luminous column is described. The device includes an elongated semiconductor electro-luminescent diode, an insulator on the surface, and a resistance layer on the insulator. The diode junction is forward biased to produce a luminous column. The voltage to be indicated is applied to the resistance layer to establish a gradient therein which tends to move carriers in the semiconductor from an area of radiative bulk recombination to an area of non-radiative recombination, thereby reducing or extinguishing the column end in relation to the magnitude of the applied voltage.</p> |
