Appl. No.:

11/171070

Inventors:

Yu Huang - Los Angeles CA, US

Assignee:

Luminoz, Inc. - Tokyo

International Classification:

G03B 21/60
G03B 21/56

US Classification:

359457, 359459, 359460

Abstract:

An off-axis Fresnel lens is disclosed that, when combined with a rear projection screen (comprising, e. g. , a lenticular lens, a diffuser, or both), enables construction of rear-projection-type screen devices (e. g. , projection television systems) that are thinner and have improved contrast and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets. Each facet, in turn, comprises top and bottom sides, one or both of which may be flat or outwardly convex. Embodiments of the invention may also include concentric opaque sections that are disposed between successive prisms, between the prism base and the output surface of the Fresnel lens, and/or between the output surface of the Fresnel lens and the input surface of the projection screen in order to improve contrast. Contrast may also be enhanced by laminating the Fresnel lens to the projection screen.

Abstract:

Off-axis total internal reflection Fresnel lenses and projection screens are disclosed that, when combined, enable construction of projection assemblies for rear-projection-type screen devices (e. g. , projection television systems) that are thinner, provide easier handling and maintenance, and have improved contrast, focusing, and resolution when compared with conventional projection screen devices. The off-axis Fresnel lens comprises a plurality of concentric, outwardly-extending, total internal reflection-type prism facets, the top side of which may be aspherical. Embodiments of the invention also include projection screens having at least one diffuser and one lenticular lens. In addition, one or more opaque layers may be used to improve contrast. The various components, e. g. , the fresnel lens, the diffuser, the lenticular lens(es), the opaque layer(s), etc.

Abstract:

A graphene nanomesh includes a sheet of graphene having a plurality of periodically arranged apertures, wherein the plurality of apertures have a substantially uniform periodicity and substantially uniform neck width. The graphene nanomesh can open up a large band gap in a sheet of graphene to create a semiconducting thin film. The periodicity and neck width of the apertures formed in the graphene nanomesh may be tuned to alter the electrical properties of the graphene nanomesh. The graphene nanomesh is prepared with block copolymer lithography. Graphene nanomesh field-effect transistors (FETs) can support currents nearly 100 times greater than individual graphene nanoribbon devices and the on-off ratio, which is comparable with values achieved in nanoribbon devices, can be tuned by varying the neck width. The graphene nanomesh may also be incorporated into FET-type sensor devices.
