Abstract
A single metal layer device, such as a display or sensor, comprises a substrate and a patterned metal layer. The patterned metal layer forms a two-dimensional array of spatially separated column line segments that each extend only partially across the display substrate in a column direction and forms a one-dimensional array of row lines extending across the display substrate in a row direction different from the column direction. The row lines and column line segments are electrically separate in the patterned metal layer. Spatially separated electrical jumpers are disposed on the display substrate and electrically connect pairs of column line segments adjacent in the column direction. Each electrical jumper has an independent jumper substrate independent of and separate from the display substrate. In certain embodiments, spatially separated light-emitting pixel circuits are disposed on a display substrate and are electrically connected to at least one row line and one column line.
