Abstract:
1. A silicon-backed microdisplay structure formed on a silicon substrate, the structure comprising: a silicon-side conductive layer formed directly on the silicon substrate; a silicon-side passivation layer 2000-6000 angstroms thick formed directly on the silicon-side conductive layer; a cover glass sheet; a glass-side conductive layer formed directly on the cover glass sheet; a glass-side passivation layer formed directly on the glass-side conductive layer; and liquid crystal material disposed directly between the glass-side passivation layer and the silicon-side passivation layer; the glass-side passivation layer being about 300-900 angstroms thick and comprising a material selected from the group consisting of CeO such that the work function balance of said silicon-backed microdisplay structure is in the range of approximately 0.2 eV to 0.4 eV.
