Abstract:
The pcLED pixels in a phosphor-converted LED array each comprise an optical element on the light-emitting surface above the phosphor layer. In methods for making such pixelated LED arrays, a thin layer of a sacrificial phosphor carrier substrate is retained as the optical element on the output surface of the phosphor pixels upon completion of the fabrication process.
