Ultra-smooth sidewall pixelated array LEDs

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