    Abstract: A display device includes a display layer having a plurality of organic light-emitting diodes (OLEDs) and an encapsulation layer covering a light-emitting side of the display layer. The encapsulation layer includes a plurality of first polymer projections on display layer, the plurality of first polymer projections having spaces therebetween, and a first dielectric layer conformally covering the plurality of first polymer projections and any exposed underlying surface in the spaces between the first polymer projections, the dielectric layer forming side walls along sides of the first polymer projections and defining wells in spaces between the side walls.

    Abstract: An apparatus for positioning micro-devices on a destination substrate includes a first support to hold a destination substrate, a second support to provide or hold a transfer body having a surface to receive an adhesive layer, a light source to generate a light beam, a mirror configured to adjustably position the light beam on the adhesive layer on the transfer body, and a controller. The controller is configured to cause the light source to generate the light beam and adjust the mirror to position the light beam on the adhesive layer so as to selectively expose one or more portions of the adhesive layer to create one or more neutralized portions. The transfer body and the destination substrate are moved away from each other and one or more micro-devices corresponding to the one or more neutralized portions of the adhesive layer remain on the destination substrate.

    Abstract: Systems and methods for processing films on the surface of a substrate are described. The systems possess aerosol generators which form droplets from a condensed matter (liquid or solid) of one or more precursors. A carrier gas is flowed through the condensed matter and push the droplets toward a substrate placed in a substrate processing region. An inline pump connected with the aerosol generator can also be used to push the droplets towards the substrate. A direct current (DC) electric field is applied between two conducting plates configured to pass the droplets in-between. The size of the droplets is desirably reduced by application of the DC electric field. After passing through the DC electric field, the droplets pass into the substrate processing region and chemically react with the substrate to deposit or etch films.

    Abstract: Embodiments described herein relate to flat optical devices and methods of forming flat optical devices. One embodiment includes a substrate having a first arrangement of a first plurality of pillars formed thereon. The first arrangement of the first plurality of pillars includes pillars having a height h and a lateral distance d, and a gap g corresponding to a distance between adjacent pillars of the first plurality of pillars. An aspect ratio of the gap g to the height h is between about 1:1 and about 1:20. A first encapsulation layer is disposed over the first arrangement of the first plurality of pillars. The first encapsulation layer has a refractive index of about 1.0 to about 1.5. The first encapsulation layer, the substrate, and each of the pillars of the first arrangement define a first space therebetween. The first space has a refractive index of about 1.0 to about 1.5.
