Fabrication method for emissive display with light management system

A method for managing the direction of light emitted from an emissive display substrate, the method comprising:

• providing a transparent substrate and a plurality of emissive element wells;
• forming light blocking material well sidewalls;
• populating the wells with emissive elements using a fluidic assembly process;
• and,
• in response to the light blocking material sidewalls, preventing the propagation of light between adjacent wells.

A method for fabricating an emissive display substrate with a light management system, the method comprising:

• providing a transparent first substrate with a top surface;
• forming a light blocking material film layer overlying the first substrate top surface;
• forming a plurality of emissive element wells in the light blocking material film layer;
• and,
• using a fluidic assembly process, populating the emissive element wells with emissive elements.
