Abstract
This invention discloses methods and apparatus to form Thin Film Nanocrystal Integrated Circuit transistors upon Three-dimensionally Formed Insert Pieces. In some embodiments, the present invention includes incorporating the Three-dimensional Surfaces with Thin Film Nanocrystal Integrated Circuit based thin film transistors, electrical interconnects, and energization elements into an Insert Piece for incorporation into Ophthalmic Device. In some embodiments, the Insert Piece may be directly used as a Media Insert or incorporated into an Ophthalmic Device.
Claims39
An ophthalmic device comprising:
- a first media insert comprising an active optical device, a first thin film nanocrystal transistor, a first energization element and a first conductive trace, wherein the first thin film nanocrystal transistor comprises an n-type nanocrystal layer, wherein the first energization element is proximate to the first conductive trace so that the first energization element is in electrical communication with the first thin film nanocrystal transistor, wherein the active optical device comprises a liquid meniscus lens element having two immiscible fluids forming a meniscus therebetween, wherein the active optical device is in electrical communication with the first energization element and the first thin film nanocrystal transistor, and wherein the active optical device is configured to change the focal characteristics of the ophthalmic device upon application of an electrical charge to change the shape of the meniscus;
- and
- a hydrogel material surrounding or encapsulating the first media insert.
An ophthalmic device comprising:
- a first media insert having a three-dimensional surface, wherein first the media insert comprises at least a first thin film nanocrystal transistor, a first energization element and a first conductive trace, wherein the first thin film nanocrystal transistor comprises a n-type nanocrystal layer, and wherein the first energization element is proximate to the first conductive trace so that it is in electrical communication with the first thin film nanocrystal transistor;
- and
- a hydrogel material surrounding or encapsulating the first media insert.
