Abstract
A display is disclosed. The display includes a plurality of pixels configured to emit light. The display also includes a plurality of pixel control circuits that are each configured to regulate emission of light from a pixel. The pixel control circuits each include one or more two-terminal switching devices that include an organic semiconductor.
Claims55
A method of forming an active matrix display, comprising:
- obtaining a substrate for use in a back plane of the display;
- and
- forming a plurality of pixel control circuits on the substrate, each pixel control circuit comprising at least one three-layer two-terminal switching device and being configured to regulate light from a pixel;
- wherein forming at least one three-layer two-terminal switching device comprises
- forming a first electrode of the switching devices;
- depositing a single layer of semiconductor from a solution over at least a portion of the first electrode, wherein said depositing comprises forming a patterned layer of the semiconductor;
- and
- forming a second electrode over at least a portion of the semiconductor and overlying at least a portion of the first electrode.
