设计并制作了一种使用电光调制的隐形透镜嵌入式显示器。使用客体-主体液晶配置，制造球形变形的液晶单元，其包含聚（3，4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）作为导电层和倾斜蒸发的SiO2作为取向层。在PEDOT：PSS的顶部蒸发额外的SiO2缓冲层，以克服与光刻限定的间隔物的图案化的兼容性问题。虽然对比度适中，但可以清楚地观察到图案化调制，这表明我们的方法和制造工艺最终可以导致完全像素化的接触透镜显示器。
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.
