    Abstract: Methods and apparatus are described herein for measurement of droplets dispensed from a printhead of an inkjet printer onto a substrate. An inkjet printer described herein comprises a printhead assembly comprising a printhead and an imaging system, the imaging system comprising a camera and a strobed LED source; and a deposition unit for positioning a substrate to receive droplets dispensed from the printhead and for imaging the droplets using the imaging system and the strobed LED source. Methods described herein comprise dispensing droplets of a liquid from a printhead of a printhead assembly of an inkjet printer onto a substrate; positioning the substrate with respect to an imaging system coupled to the printhead assembly, the imaging system comprising a camera and an LED light source; and imaging the droplets on the substrate by relatively scanning the substrate and the imaging system and strobing the LED light source.

    Abstract: A display device that uses one or more light coupling layers is described herein, along with methods of making such devices. One device includes an array of blue light emitting elements formed on a substrate, a light coupling material formed over the array of blue light emitting elements, and a quantum dot light converting material disposed in a portion of a pixel structure formed over the array of blue light emitting elements. The light coupling material has a high refractive index and may be, or include, a polymer material.

    Abstract: A system comprises a floatation table comprising a plurality of ports to flow gas sufficient to produce a gas bearing to float a substrate over the floatation table; a fluidic network coupled to supply gas to the plurality of ports of the floatation table; and a controller configured to control the fluidic network to independently control flows of gas through ports of the plurality of ports disposed in each of a first zone, a second zone, and a third zone of the floatation table. The first, second, and third zones are defined by sections of the floatation table extending parallel to a direction the substrate is conveyed along the floatation table. The first zone is defined by a central section of the floatation table disposed between two sections defining the second zone, and the first and second zones are disposed between two sections defining the third zone.

    Abstract: A mechanism is described that features a body with three link points, each with a rigid adjustable length link member coupling the link point to a ground using biaxial rotary couplings giving rotation orientation to position the body in three dimensions relative to the three grounds. An inkjet printer is also described using the mechanism with a substrate support.

    Abstract: A system may include a support surface for supporting a substrate, a plurality of first passages arranged to distribute flows of a first gas to establish a gas bearing to float the substrate above the support surface, and a plurality of second passages arranged to distribute flows of a second gas to convey the substrate along the support surface. A method may include floating a substrate above a support surface of a substrate support apparatus via a gas bearing; and while floating the substrate, conveying the substrate along the support surface by flowing gas toward a surface of the substrate and in a non perpendicular direction relative to the surface of the substrate.
