Abstract
A method is provided for fabricating an emissive display substrate with a light management system. The method provides a transparent first substrate with a top surface and forms a plurality of emissive element wells. The well sidewalls are formed from a light absorbing material or a light reflector material. In one aspect, a light blocking material film layer is formed overlying the first substrate top surface, and the emissive element sidewalls are formed in the light blocking material film layer. In another aspect, a transparent second substrate is formed overlying the first substrate top surface. Then, the emissive element wells are formed in the second substrate with via surfaces, and the light blocking material is deposited overlying the well via surfaces. Additionally, the light blocking material may be formed on the bottom surface of each well. An emissive display substrate with light management system is provided below.
