High density pixelated LED and devices and methods thereof

A method for fabricating a solid-state lighting device, the method comprising:

• defining a plurality of LEDs on a single substrate, wherein each LED of the plurality of LEDs comprises an active layer on a substrate portion and an anode and a cathode that form an anode-cathode pair in conductive electrical communication with the active layer, each LED of the plurality of LEDs comprises a front side and a back side that opposes the front side, the substrate portion of each LED is closer to the front side than to the back side, the anode-cathode pair of each LED is arranged along the back side, the plurality of LEDs defines a plurality of pixels, and the plurality of LEDs is configured to generate LED emissions;
• providing a plurality of recesses registered with boundaries between at least some LEDs of the plurality of LEDs;
• providing a light-reflective first material in the plurality of recesses;
• providing a light-scattering-second material on the light reflective first material in the plurality of recesses;
• applying a lumiphoric material over the plurality of LEDs and over the light-scattering second material, wherein the lumiphoric material is arranged to receive at least a portion of the LED emissions and responsively generate lumiphor emissions, and wherein the light-scattering second material is arranged between the light-reflective first material and the lumiphoric material.
