1. A single metal layer display, comprising:

  • a display substrate having a display surface with a display area;

    a patterned metal layer disposed in or on the display substrate at least partially in the display area, the patterned metal layer at least partially exposed on the display surface,wherein the patterned metal layer forms a two-dimensional array of spatially separated column line segments in the display area, each column line segment extending only partially across the display area in a column direction;

    wherein the patterned metal layer forms a one-dimensional array of row lines extending across the display area in a row direction different from the column direction, andwherein the row lines and column line segments are electrically separate in the patterned metal layer;

    a plurality of spatially separated electrical jumpers disposed in the display area on the display surface, each electrical jumper electrically connected to two column line segments adjacent in the column direction to electrically connect the adjacent column line segments and form a one-dimensional array of electrically continuous column lines extending across the display area in the column direction, wherein each electrical jumper comprises an independent jumper substrate independent of and separate from the display substrate and independent of and separate from the jumper substrate of any other electrical jumper; and

    a plurality of spatially separated light-emitting pixel circuits disposed in the display area on the display surface, each pixel circuit electrically connected to at least one row line of the array of row lines and one column line of the array of electrically continuous column lines.
