Title:
電子ビーム誘導チャンネルを有する表示装置
Document Type and Number:
Japanese Patent JP2006512720
Kind Code:
A
Abstract:
A display device is provided with electron beam guiding channels ( 10 ). A channel ( 10 ) receives an electron beam (EB) and guides the beam (EB) parallel to a luminescent display screen ( 40 ). The electron beam (EB) is extractable from the channel ( 10 ), after which the beam (EB) impinges on the display screen ( 40 ). Electrode means ( 11, 12, 13 ) defining an electric potential in the channel ( 10 ) are provided for guiding and extracting the electron beam (EB). The electrode means ( 11, 12, 13 ) are arranged in such a way that in the channel ( 10 ), the electron beam (EB) is focused in a transverse direction being perpendicular to the channel ( 10 ) and parallel to the display screen ( 40 ). Thus, the electron transmission of the beam guiding channel ( 10 ) can be particularly high.
