Claim 0:
1. A display device, comprising:
a display layer having a plurality of light-emitting diodes with each light-emitting diode comprising a light generating layer, the display layer having a capping layer that extends above all light emitting materials in the display device and over spaces between the plurality of light emitting diodes to provide substantially planar top surface that spans the plurality of light-emitting diodes and the spaces between the plurality of light emitting diodes; and
an encapsulation layer covering a light-emitting side of the display layer above the substantially planar top surface, the encapsulation layer including
a plurality of polymer projections on the display layer, wherein the plurality of polymer projections have spaces therebetween that expose the substantially planar top surface of the display layer, and wherein each polymer projection has an upper surface that is substantially parallel to the substantially planar top surface and sides extending from the substantially planar top surface to the upper surface, and
a first dielectric layer conformally covering the plurality of polymer projections and the substantially planar top surface of the display layer in the spaces between the polymer projections, wherein the first dielectric layer forms side walls along the sides of the polymer projections and defining wells extending into spaces between the side walls so that the wells extend below upper surfaces of the polymer projections.
