An optical isolation material may be applied to walls of a first cavity and a second cavity in a wafer mesh. A wavelength converting layer may be deposited into the first cavity to create a first segment and into the second cavity to create a second segment. The first segment may be attached to a first light emitting device to create a first pixel and the second segment to a second light emitting device to create a second pixel. The wafer mesh may be removed.

Converter fill for LED array

A method includes mounting a ceramic phosphor on an acrylic-free and metal-containing catalyst-free tacky layer of a dicing tape, dicing the ceramic phosphor from the dicing tape into ceramic phosphor plates, removing the ceramic phosphor plates from the dicing tape, and attaching the ceramic phosphor plates on light-emitting device (LED) dies.
