Abstract
A repairable matrix-addressed system includes a system substrate, an array of electrically conductive row lines, and an array of electrically conductive column lines disposed over the system substrate. The row lines extend over the system substrate in a row direction and the column lines extend over the system substrate in a column direction different from the row direction to define an array of non-electrically conductive intersections between the row lines and the column lines. An array of electrically conductive line segments is disposed over the system substrate. The line segments extend over the system substrate substantially parallel to the row direction and have a line segment length that is less than the distance between adjacent column lines. Each line segment is electrically connected to a column line. One or more devices are electrically connected to each row line and to each line segment adjacent to the row line.
