<p>The invention relates to a display screen, addressing of which is provided by means of non linear elements formed by two diodes placed in series and in opposition. The invention provides non linear elements 51 formed such that the two diodes forming them have a common doped semi conductor material part, the characteristics of this common part being such that all the non linear elements have, for the same control voltage, the same operating point in the current-voltage characteristic. The desired characteristics are attained by providing the doping level of the common semiconductor material to be such that its conductivity is greater than a particular value. <IMAGE></p> |
