  • Patent number: 10192478
    Abstract: Pixel locations in an addressable display are defined by metal landings on a top surface of a flexible substrate, such as by depositing a metal film and etching the film. 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.

  • Patent number: 9231210
    Abstract: A vapor deposition source (60), a plurality of limiting plates (81) and a vapor deposition mask (70) are disposed in this order. A substrate spaced apart from the vapor deposition mask at a fixed interval is moved relative to the vapor deposition mask. Vapor deposition particles (91) discharged from vapor deposition source openings (61) of the vapor deposition source pass through between neighboring limiting plates, pass through mask openings (71) formed in the vapor deposition mask, and adhere to the substrate, whereby coating films (90) are formed. The limiting plates limit the incidence angle of the vapor deposition particles that enter the mask openings, as viewed in the relative movement direction of the substrate. In this way, an organic EL element can be formed on a large-sized substrate without increasing the pixel pitch or reducing the aperture ratio.

  • Patent number: 9040969
    Abstract: The organic electroluminescence display device has a laminated portion on a base substrate. The device may have a cavernous portion formed by exploding a part of the laminated portion in a screening processing. A protective layer is formed to cover a whole surface of a wall defining the cavernous portion. Therefore, substances contained in the air are prevented from contacting to an organic electroluminescence layer at least partially defining the cavernous portion. Therefore, even if moisture is contained in the air, it is possible to prevent moisture from being absorbed by the organic electroluminescence layer. Moreover, since moisture is not absorbed by the organic electroluminescence layer, it is possible to reduce irregular spot on the device. In addition, it is possible to reduce a short circuit at an open defective portion.
