摘要：

A contact lens embeddable display using electro-optic modulation was designed and fabricated. Using a guest-host liquid crystal configuration, a spherically deformed liquid crystal cell was fabricated comprising poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS) as a conductive layer and obliquely evaporated SiO2 as an alignment layer. An additional SiO2 buffer layer was evaporated on top of the PEDOT: PSS to overcome compatibility problems with the patterning of the photolithographically defined spacers. Although the contrast is modest, a patterned modulation could clearly be observed, indicating that our approach and fabrication process could eventually lead to a fully pixelated contact lens display. © Copyright 2013 Society for Information Display.
