  • Publication number: 20200335672
    Abstract: A wavelength converting layer is partially diced to generate a first and second wavelength converting layer segment and to allow partial isolation between the first segment and the second segment such that the wavelength converting layer segments are connected by a connecting wavelength converting layer. The first and second wavelength converting layer segments are attached to a first and second light emitting device, respectively to create a first and second pixel. The connecting wavelength converting layer segment is removed to allow complete isolation between the first pixel and the second pixel. An optical isolation material is applied to exposed surfaces of the first and second pixel and a sacrificial portion of the wavelength converting layer segments and optical isolation material attached to the sacrificial portion is removed from a surface facing away from the first light emitting device, to expose a emitting surface of the first wavelength converting layer segment.
