Abstract:
Over a flexible substrate are formed column lines for a display. Over the substrate and column lines are formed a reflective hydrophobic mesh defining pixels. Over the mesh and column lines is printed an LED ink containing microscopic LED dies. The LED ink de-wets from the mesh. The ink is then cured to electrically connect the bottom electrodes of the LEDs to the column lines within the openings (cells) of the mesh. A dielectric then encapsulates the LEDs while exposing the top electrodes of the LEDs. Transparent row lines are then formed along the rows of the mesh to electrically contact the top electrodes in each row. The LEDs within any cell can be turned on by address in a pair of row and column lines. Phosphor dots may be printed to over blue-emitting LEDs to create red, green, and blue sub-pixels for a full color display.
