Title: DISPLAY DEVICE OF THE FLAT-PANEL TYPE COMPRISING AN ELECTRON TRANSPORT DUCT AND A SEGMENTED FILAMENT
Abstract:
A display device comprising electron-transport ducts having entrance apertures for electrons and means for generating electrons and injecting electrons into the transport ducts via said entrance apertures. Measures have been taken to improve the picture quality. For example, the location of the entrance aperture is not the same for each transport duct, but instead shows a variation. This enables an improved control of the electron flow in the transport ducts to be achieved; in particular crosstalk between the transport ducts can be reduced.
