ABSTRACT:
An image display apparatus includes a rear plate having a plurality of electron-emitting devices, a face plate having a plurality of pixels, each pixel having one or more phosphors that emit fluorescence in response to electrons emitted from the electron-emitting devices, and a drive circuit for driving the electron-emitting devices. At least one of the phosphors is CaAlSiN3:Eu2+; and the electrons are supplied to the pixels for 2 μs to 70 μs from the electron-emitting devices on a scan basis, each of which devices supplies current to one or more of the phosphors.
