  • Image display apparatus
    Patent number: 7626324
    Abstract: An image display apparatus of smaller beam deviation is provided by making smaller the absolute value of an angle formed by an initial velocity vector of an electron emitted from the first electron-emitting devices closest to a spacer 100 and a line parallel to the longitudinal direction of a spacer 100, rather than the absolute value of an angle formed by an initial velocity vector of an electron emitted from the second electron-emitting devices secondary closer to the spacer 100 and the line parallel to the longitudinal direction of the spacer 100.
    Type: Grant
    Filed: December 6, 2007
    Date of Patent: December 1, 2009
    Assignees: Canon Kabushiki Kaisha, Kabushiki Kaisha Toshiba
    Inventors: Takeshi Yamatoda, Akihiko Yamano
  • Compensation of warping in display apparatus substrate
    Patent number: 7592743
    Abstract: A miss landing measure on a face plate of electrons emitted from electron-emitting devices by the warping of a rear plate and the face plate accompanying heat processes, such as seal bonding, is provided. Initial velocity vectors of electrons emitted from an electron-emitting area of an electron-emitting device formed on the rear plate has a distributed tendency according to an in-plane distribution of normal line directions of the rear plate so that the electrons emitted from each of the plurality of electron-emitting devices may irradiate each of the plurality of light emitting portions, corresponding to each of the electron-emitting devices, formed on the face plate.
