Display substrate edge patterning and metallization

A device comprising:

• a display panel comprising a substrate and a plurality of signal lines supported by the display substrate, the plurality of signal lines extending across a first side of the substrate to define an active area of the display panel;
• and
• a display control circuit configured to control the display panel and disposed along a second side of the substrate, the second side being opposite the first side;
• wherein:
• the substrate has a patterned edge;
• the patterned edge comprises a plurality of notches;
• and
• each signal line of the plurality of signal lines is disposed in a respective notch of the plurality of notches to traverse the edge to establish an electrical connection between the plurality of display signal lines and the display control circuit.

A method of fabricating a display, the method comprising:

• patterning a display substrate supported by a carrier substrate such that the display substrate has a patterned edge with a plurality of notches;
• forming display structures on a first side of the display substrate, the display structures comprising a plurality of signal lines to define an active area of the display, each signal line of the plurality of signal lines being disposed in a respective notch of the plurality of notches;
• removing the carrier substrate from a second side of the display substrate opposite the first side;
• and
• attaching a control circuit along the second side of the display substrate, the control circuit comprising a plurality of contacts, wherein attaching the control circuit comprises establishing, at the patterned edge, an electrical connection between each respective contact of the plurality of contacts and a respective signal line of the plurality of signal lines.
