  • 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

  • Phosphor converted LED with high color quality
    Patent number: 11233180
    Abstract: A light emitting diode (LED) device may include an LED die having a first surface on a substrate. A first phosphor layer may be formed on a second surface and sides of the LED die. The second surface may be opposite the first surface. A second phosphor layer may be formed on the first phosphor layer. The second phosphor layer may have a peak emission wavelength (Lpk2) located between a peak emission wavelength of the LED die (LpkD) and a peak emission wavelength of the first phosphor layer (Lpk2).
