Patent ID: 7157928

Claim:
A method to detect leaky elements in a matrix-structured electronic device, wherein said device includes a plurality of elements, a plurality of first lines, and a plurality of second lines, wherein said plurality of first lines intersect said plurality of second lines, and said plurality of elements are at said intersections and are coupled to said plurality of first lines and said plurality of second lines, said method comprising: (a) selecting a particular one of said plurality of first lines; (b) applying a first voltage to said particular first line that is selected; (c) applying a second voltage to one or more of said plurality of first lines that are not selected; (d) floating said plurality of second lines; and (e) measuring a plurality of voltages on said plurality of second lines, each of said plural measured voltages identifying a particular one of said plural elements which is coupled to both a corresponding selected first line and the corresponding second line.
