The substrate surface may be hydrophobic so that the hydrophobic surface is exposed between the metal landings. The substrate has conductive vias that connect the metal landings to traces on a bottom surface of the substrate for connection to addressing circuitry. LED ink is then blanket-printed over the top surface and cured to electrically connect bottom electrodes of the LEDs to the metal landings. LEDs that fall between the landings are ineffective. A dielectric layer is blanket-printed which exposes the top electrodes, and a transparent conductor layer is blanket-printed over the LEDs to connect all LEDs associated with an individual pixel location in parallel. Accordingly, all printed steps can be performed without any alignment.

  • Patent number: 9961782
    Abstract: A printer deposits material onto a substrate as part of a manufacturing process for an electronic product. At least one mechanical component experiences mechanical error, which is mitigated using transducers that equalize position of a transported thing, e.g., to provide an “ideal” conveyance path; a substrate conveyance system and/or a printhead conveyance system can each use transducers in this manner to improve precise droplet placement. In one embodiment, errors are measured in advance, with corrections being “played back” during production runs to mitigate repeatable transport path error. In a still more detailed embodiment, the transducers can be predicated on voice coils, which cooperate with a floatation table and floating, mechanical pivot assembly to provide frictionless, but mechanically-supported error correction.
