Curved LCD could be used for displays in contact lenses
"Normally, flexible displays using liquid crystal cells are not designed to be formed into a new shape, especially not a spherical one,” explained Jelle De Smet, the main researcher on the project. “Thus, the main challenge was to create a very thin, spherically curved substrate with active layers that could withstand the extreme molding processes. Moreover, since we had to use very thin polymer films, their influence on the smoothness of the display had to be studied in detail. By using new kinds of conductive polymers and integrating them into a smooth spherical cell, we were able to fabricate a new LCD-based contact lens display"
