Abstract
This invention discloses methods and apparatus to form organic semiconductor transistors upon three-dimensionally formed insert devices. In some embodiments, the present invention includes incorporating the three-dimensional surfaces with organic semiconductor-based thin film transistors, electrical interconnects, and energization elements into an insert for incorporation into ophthalmic lenses. In some embodiments, the formed insert may be directly used as an ophthalmic device or incorporated into an ophthalmic device.
Claims13
A method of forming an ophthalmic device comprising:
- attaching a first conductive trace to a thin film transistor;
- depositing an organic semiconductor layer fixedly attached the thin film transistor onto an ophthalmic insert device;
- forming an encapsulating layer around the ophthalmic lens insert;
- and
- forming an ophthalmic device encapsulating the ophthalmic insert device.
