Patent ID: 8558978

Claim:
An electronic device, comprising: one or more input structures; a storage structure encoding one or more executable routines; a processor capable of receiving inputs from the one or more input structures and of executing the one or more executable routines when loaded in a memory; and a liquid crystal display (LCD) capable of displaying an output of the processor, wherein the LCD includes: a first passivation layer disposed in contact with a second passivation layer, wherein the first passivation layer includes a refractive index less than that of the second passivation layer; a plurality of electrodes formed on a common surface of the first passivation layer; and a liquid crystal layer disposed over the plurality of electrodes, wherein the electrodes of the plurality of electrodes are spaced apart along the common surface such that portions of the liquid crystal layer are disposed between the electrodes and the first passivation layer, wherein the first passivation layer includes a plurality of regions having different refractive indices, wherein the plurality of regions includes a first region in contact with an electrode of the plurality of electrodes and a second region in contact with the liquid crystal layer, wherein the first region of the first passivation layer has a refractive index between those of the second passivation layer and the electrode, while the second region of the first passivation level has a refractive index between those of the second passivation layer and the liquid crystal layer.
