Flat panel emissive display with redundant circuit

Claim 1

A flat panel emissive display comprising: a matrix of pixels arranged in rows and columns, each pixel comprising means for emitting light when pixel current is applied thereto; at leas tone row electrode of each row of pixels; a plurality of column electrodes for each column of pixels, each pixel having at least one corresponding row electrode and a plurality of corresponding column electrodes, the plurality of column electrodes for each column of pixels comprising a single conductor with sufficient resistance to localize a short circuit condition of one of the column electrodes; driver means for selectively energizing the row electrodes corresponding to selected rows of pixels and the pluralities of column electrodes corresponding to selected columns of pixels; and redundant sets of transistors means coupled to each pixel for jointly supplying pixel current, each set of transistor means being connected to at least the one row electrode and to one of the corresponding column electrodes such that each pixel is normally activated by signals from the one row electrode and at least one of the column electrodes.
