  • Patent number: 12507520
    Abstract: Pixelated array light emitters are formed with closely-spaced pixels having ultra-smooth sidewalls. In methods for making such pixelated array light emitters, a converter layer of phosphor particles dispersed in a binder is disposed on a carrier, and then singulated by saw cuts or similar methods to form an array of phosphor pixels. The binder is fully cured prior to singulation of the converter layer. Further, the carrier is rigid rather than flexible. As a consequence of fully curing the binder and of using a rigid carrier to support the converter layer, singulation results in phosphor pixels having smooth side walls. The array of phosphor pixels is subsequently attached to a corresponding array of LEDs with an adhesive layer, separate from the binder used to form the converter layer. The pixel sidewalls may be formed with controlled morphology, for example at acute or obtuse angles with respect to the carrier.

  • Patent number: 11973167
    Abstract: A method is described for low temperature curing of silicone structures, including the steps of providing patterning photoresist structures on a substrate. The photoresist structures define at least one open region that can be at least partially filled with a condensation cure silicone system. Vapor phase catalyst deposition is used to accelerate the cure of the condensation cure silicone, and the photoresist structure is removed to leave free standing or layered silicone structures. Phosphor containing silicone structures that are coatable with a reflective metal or other material are enabled by the method.

  • Patent number: 11749786
    Abstract: An array of phosphor pixels is positioned on an array of semiconductor LED pixels with thermally curable adhesive between them. Selected LED pixels of the array are electrically activated; resulting heat cures the adhesive to attach the corresponding phosphor pixel to the activated LED pixel and to release the corresponding phosphor pixel from a carrier. Removal of the carrier removes unattached phosphor pixels, leaving behind phosphor pixels attached to the LED pixels that were activated. The process can be repeated for phosphor pixels of different colors.
