  • Converter fill for LED array
    Patent number: 11973169
    Abstract: 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.
    Type: Grant
