Abstract
A cathode ray tube (CRT) display includes a display panel having a matrix of addressable carbon nanotubes, in which each individual nanotube can be selected to help draw a corresponding electron beam from a red, green, or blue electron gun to the desired portion of the display panel, thereby creating the desired image on through the display panel.
Claims13
A cathode ray tube (CRT) display system, comprising:
- an addressable nanotube matrix having a first face and a second face;
- a plurality of electron guns directed toward the first face of the addressable nanotube matrix;
- an addressing circuit coupled to the nanotube matrix and the plurality of electron guns;
- and
- an enclosure containing the addressable nanotube matrix and at least a portion of the plurality of electron guns,
- wherein the addressable nanotube matrix comprises phosphor formed over nanotubes of the nanotube matrix, wherein the phosphor is located between the plurality of electron guns and the nanotubes.
3 more elements
A method of displaying an image in a cathode ray tube (CRT) system, comprising:
- scanning a first face of a phosphor pattern with electron beams;
- turning on carbon nanotubes located on a second face of the phosphor pattern, corresponding to the scanning of the phosphor pattern;
- wherein the addressable nanotube matrix comprises phosphor formed over nanotubes of the nanotube matrix, wherein the phosphor is located between the plurality of electron guns and the nanotubes;
- and
- displaying an image resulting from the electron beams impinging on the first face of the phosphor pattern.
