ABSTRACT:
An electrooptical display comprises a matrix of display elements in combination with isolation elements providing a display element circuit for each display element. Compensative redundancy elements are also included in each of the display element circuits wherein circuits containing at least one defect in either or both of a isolation element or a compensative redundancy element are relieved of the defect by their removal, such as, by electrical insolation, from the defective display element circuit. At least one combination of an insolation element and a compensative redundancy element containing the defect are removed so that the resultant voltage characteristics for writing capability relative to relieved display element circuits in the display will remain substantially the same as the existing voltage characteristics provided for writing capability relative to normal functioning display element circuits whereby the overall intensity of the display will remain substantially uniform in spite of the removal of the pair of elements.
