Abstract
Systems and methods for producing thin film transistor structures useful in controlling electronic displays. Thin film transistors are fabricated using all-additive methods including printing techniques, soft lithography and material deposition methods. The thin film transistors can be deposited with the gate on the bottom or on the top of the structure. The deposition methods include the possibility of isolating nearly completely the transistor structure from the electronic display devices, so as to minimize or eliminate deleterious interactions therebetween.
Claims26
A method of manufacturing an addressing device for an electronic display comprising:
- a) providing a substrate;
- and
- b) fabricating the addressing device adjacent a surface of the substrate by:
- (i) treating said surface to control one of a contact angle of a liquid with said surface, a surface roughness and a surface energy;
- and
- (ii) printing at least one circuit element of the addressing device.
A method of manufacturing an addressing device for an electronic display comprising:
- a) providing a substrate;
- and
- b) fabricating the addressing device adjacent a surface of the substrate by printing at least one circuit element by:
- (i) screen printing a gate structure;
- (ii) ink jet printing a dielectric material and a semiconductor;
- (iii) screen printing coarse features of a source structure and a drain structure;
- and
- (iv) printing by use of soft lithography high resolution features of the source structure and the drain structure.
